* chore: update IPinfo Lite MMDB (#941) Co-authored-by: seanthegeek <44679+seanthegeek@users.noreply.github.com> * Cap report date range and indexes created per report A report whose <date_range> spans millions of days was normalized into one record per day, exhausting memory, and with Elasticsearch or OpenSearch output created one dated index (one shard) per day, exhausting the cluster's shard budget. Reject a range longer than MAX_REPORT_SPAN_DAYS (366) or negative with InvalidAggregateReport. In both save functions, once a report has used MAX_INDEXES_PER_REPORT (31) distinct dated indexes, route further records to the report's first index, keeping their own dates, and log one warning. Refs GHSA-p85v-578x-3wcf Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com> * Catch output-stage exceptions and validate SMTP TLS report types One report sent to a monitored mailbox could make a configured output raise an exception that process_reports() did not catch. It escaped through the mailbox save callback, _main logged "Mailbox Error" and exited 1, and the batch stayed in the mailbox, so every one-shot run died on the same message and duplicated the legitimate reports in non-deduplicating outputs. Three sender-controlled inputs did it: - A failure report whose sample has an empty From:, To: or Reply-To: (To: undisclosed-recipients:; included): mail-parser gives an empty address list, and the Elasticsearch and OpenSearch saves indexed [0] (IndexError). - An SMTP TLS report with a wrong-typed field: "policy-string": [1] made the CSV writer raise TypeError; "start-datetime": 5 made the Elasticsearch, OpenSearch and Splunk saves raise AttributeError and _ensure_utc_suffix() in the PostgreSQL save raise TypeError. - An aggregate report whose <reason> has no <type> (KeyError in the CSV writer) or a <type> that xmltodict parses to a dict or a list (TypeError in its join). Fix: - Every output destination block in process_reports() now ends with the catch-all the aggregate Elasticsearch block had: the failure and SMTP TLS Elasticsearch/OpenSearch blocks, every PostgreSQL and Splunk HEC block, and the file output (its OSError/ValueError branch is kept). The error goes through log_output_error(), so the batch is reported unsaved and fail_on_output_error still raises ParserError. - parse_smtp_tls_report_json() and its helpers check each field against the type RFC 8460 section 4.4 gives it and raise InvalidSMTPTLSReport otherwise: strings for organization-name, report-id, policy-domain, policy-type, result-type and the optional failure-details fields; contact-info a string or a list of strings; policy-string and a list mx-host-pattern lists of strings; the session counts integers or null; failure-details a list of objects; start-datetime and end-datetime strings of at most 64 characters that the outputs' own conversions accept. dateutil took 12.4 s to fail on a 1,000,000-digit date, hence the length bound. - _parse_report_record() makes a reason's type and comment a string or None (a dict unwrapped with _text(), a list as its str()), and the aggregate CSV writer reads both with .get(). - The Elasticsearch and OpenSearch failure saves flatten From, To and Reply-To with a helper that returns None for an empty list, and leave such a header out of the document and the duplicate query. - The Splunk SMTP TLS save converts begin_date inside its try, so a bad value raises SplunkError; _ensure_utc_suffix() returns a non-string unchanged. Refs GHSA-4272-4r8g-6c5h Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Limit XML nesting depth and node count in aggregate reports parse_aggregate_report_xml() gave the decompressed report (up to the 100 MiB decompression cap) to xmltodict with no limit on depth or element count. xmltodict keeps one stack entry per open element and expat reports missing end tags only at the end of the input, so a few KB of gzipped unclosed <a> tags grew to gigabytes of RSS and the kernel OOM killer ended the process before the message was moved; a wide document of millions of siblings did the same at a smaller scale. A failed first parse also re-parsed the document through lxml recovery, which has no node limit, and a second xmltodict pass. _NoDoctypeExpat.ParserCreate() now returns a proxy around the expat parser. pyexpat parsers cannot be subclassed and xmltodict assigns its handlers after ParserCreate() returns, so the proxy's __setattr__ wraps StartElementHandler to count depth and nodes (elements plus attributes) and EndElementHandler to decrement depth, and forwards every other attribute. Over MAX_XML_DEPTH (100) or MAX_XML_NODES (5,000,000) it raises before xmltodict's handler runs. Both xmltodict.parse() call sites turn that into InvalidAggregateReport naming the limit; the first does so instead of trying lxml recovery. The lxml recovery path now runs a counting pass first, with a parser target that builds no tree and counts elements, attributes and namespace declarations against MAX_XML_NODES; the tree is built only for a document within the limit. Depth there is bounded by libxml2's own limit of 256 (huge_tree stays off) and then by the second xmltodict pass. A 22 MiB wide document behind a malformed XML declaration peaked at +1532 MiB before this pass and +23 MiB after. The largest aggregate sample (909 KB) has 32,019 nodes, so a legitimate report at the 100 MiB cap stays near 3.6 million. Refs GHSA-q7gm-8cj9-94hr Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Create Elasticsearch/OpenSearch indexes with mapping guards create_indexes() and create_data_streams() created indexes and the data stream template with settings only, so the cluster typed every report field from the first document that held it, with date_detection on. A sender could be first into a day's index (its name comes from the report) and poison it: a report_id of "2026-11-09" mapped report_id as a date, a failure sample header named "Subject.x" mapped sample.headers.subject as an object, and samples with invented header names used up index.mapping.total_fields.limit. Every later legitimate report for that index was then rejected and ended up in Unsaved; in data stream mode this lasted until a rollover. Both functions now take a mappings body, and the three save functions pass one per report type. Each turns date_detection off and declares the fields that hold dates (@timestamp, date_range, date_begin, date_end, arrival_date, sample.date) as dates, the type date detection gave them before; on the sample reports every other field keeps its old type. The failure mapping maps sample.headers as an object with dynamic: false and declares, as text with a keyword sub-field (the dynamic string default), every header the shipped dashboards reference plus date, message-id and cc; all headers still stay in _source. A "." in a header name is replaced with "_" before the header is stored. The index is now created through the client's indices.create with the settings and mappings body, because opensearch-py's Index.create cannot take a mappings argument; the data stream template merges the mappings with its @timestamp date mapping. Existing indexes are not changed. The other report fields stay dynamic and object-mapped (no nested), which the dashboards need (issue #169). Refs GHSA-qpcg-29vr-jwm3 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Read the RFC 8460 mx-host key in SMTP TLS reports RFC 8460 section 4.4 keys a policy's MX host patterns "mx-host"; its schema line is "mx-host": mx-host-pattern, where mx-host-pattern is the value type, described as "a JSON array of strings", and the RFC's Appendix B example gives the value as a plain string. The parser read only "mx-host-pattern", so every RFC-conformant report lost the field (samples/smtp_tls/rfc8460.json, the Appendix B example, among them). _parse_smtp_tls_report_policy() now reads "mx-host" as a string or a list of strings, a string becoming a one-element list, and falls back to "mx-host-pattern" (same rules) when "mx-host" is absent, null or empty. Any other type raises InvalidSMTPTLSReport. The output key is still mx_host_patterns, so the PostgreSQL TEXT[] column, the Elasticsearch/OpenSearch field and the CSV column are unchanged. Refs #942 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Reject over-limit messages with the mailsuite guard parse_report_email() and parse_email() handed every message to mail-parser and the email package with no bound on blank lines, header lines, header field size, MIME parts or nested multiparts, so a small crafted message took seconds to minutes and gigabytes to parse while the rest of the mailbox waited. Both now call mailsuite.utils.check_message_limits() first, one linear pass. parse_report_email() turns MessageLimitExceeded into InvalidDMARCReport so the mailbox loop files the message under Invalid; parse_failure_report() turns one from the sample into InvalidFailureReport. The mailsuite floor rises to 2.3.5, which adds the guard. Messages nested deeper than 100 multiparts are now rejected by the guard instead of reaching the recursion handler; the tests that used the 400-level message expect the new message. Refs GHSA-qcc2-4x3v-v4g7 Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com> * Cite RFC 7489 §6.3 for the daily report interval The comment on MAX_REPORT_SPAN_DAYS cited RFC 7489 Appendix A for the one-day aggregate report. The daily interval comes from §6.3: the "ri" tag requests the interval between aggregate reports, and its default is 86400 seconds. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add the 11.2.2 changelog: five advisories and #942 One Security bullet per advisory (GHSA-qcc2, GHSA-q7gm, GHSA-p85v, GHSA-4272, GHSA-qpcg) and a Bug fixes bullet for the RFC 8460 mx-host key. The version in constants.py is bumped by the release pull request. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Keep the date range rejection message and pyright's analysis With the XML limits and the date range limit merged, parse_aggregate_report_xml() became too complex for pyright to analyze ("Code is too complex to analyze"), and the date range rejection, raised inside the function's catch-all, reached the caller as "Unexpected error: Report date range spans ...". The date range check moves to _check_report_span() and the second xmltodict pass to _parse_limited_xml(), which raises the XML limit breach as InvalidAggregateReport; the catch-all now re-raises an InvalidAggregateReport as it is. The tests assert the message is not re-wrapped. Refs GHSA-p85v-578x-3wcf Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Put the over-limit failure samples in a delivery-status body mailsuite 2.3.5's check_message_limits() follows the MIME structure and counts blank lines only inside message/delivery-status bodies, the shape whose parse cost is per blank line; blank lines elsewhere in a body are not limited. The two failure-sample tests used blank lines in a plain body, which the final check accepts, so they now put them in a delivery-status body. parsedmarc's call with the default limits is unchanged. Refs GHSA-qcc2-4x3v-v4g7 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Describe the final mailsuite check and the index cap in the docs The GHSA-qcc2 changelog bullet now describes check_message_limits() as mailsuite 2.3.5 ships it: limits follow the MIME structure, and body lines outside message/delivery-status bodies are not limited. The changelog section moves to Unreleased, as parsedmarc's AGENTS.md has fix pull requests write it; the release pull request names the version. The Elasticsearch and OpenSearch pages now say that an address header with no address is left out of the failure document, and that a report spanning more than 31 days saves its later records to its first dated index. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Bound records times days in normalization and fix the span message The date range limit bounds how far one record is split, but not how many records are split: 10,000 records over 366 days, each with a count of 1,000,000 (3.3 MB of XML), produced 3,670,000 records in 13.5 s and 1.7 GB, and 30,000 of them (a 44 KB gzip) ran out of memory and reached the caller as "Unexpected error: ". A report whose split would exceed MAX_NORMALIZED_RECORDS (250,000) now keeps its records whole over its own range, with timespan_requires_normalization false and one warning; a large legitimate multi-day report is kept rather than rejected. The record loop moves to _parse_report_records() so pyright can still analyze parse_aggregate_report_xml(). The span message used float division, which raises OverflowError for an <end> of 4,001 digits; it now uses integer division. The index-routing warning escapes the sender's report ID with sanitize_for_log(). The changelog and the Elasticsearch and OpenSearch pages say the index cap is per report, that dated index names still come from report dates, and that data streams are affected by neither. Refs GHSA-p85v-578x-3wcf Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Drop XML attributes from aggregate reports before they are used xmltodict turns an element with an attribute, such as <p a="1">none</p>, into {"@a": "1", "#text": "none"}. Such objects passed through the parser into Elasticsearch and OpenSearch documents for version, p, fo, disposition, envelope_to and other scalar fields, so the first one mapped the field as an object and every later report to that index failed, and hundreds of attributes on one element used up total_fields.limit. The parsed report now goes through one linear pass that replaces an element with only attributes and text by its text and drops attributes from the others; the existing _text() calls now receive strings. The changelog and the Elasticsearch and OpenSearch pages also say that an existing data stream's next backing index gets the guarded mappings, since parsedmarc puts the template again in every process, and the indexed-header comment and changelog name cc as the one header added to those the dashboards reference. Refs GHSA-qpcg-29vr-jwm3 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Reject lone surrogates in SMTP TLS reports and guard the stdout print An SMTP TLS string field holding a lone surrogate (JSON "\ud800") passed every type check and survived json.dumps(ensure_ascii=False), and print(output_str) in process_reports(), outside every try, raised UnicodeEncodeError: parsedmarc exited 1, and in mailbox mode the error escaped the save callback. RFC 8460 section 4 reports are I-JSON, whose RFC 7493 section 2.1 forbids surrogate code points, so the string and string-list checks now reject one as InvalidSMTPTLSReport, and the print records a UnicodeEncodeError as a "Standard output" output error. The _smtp_tls_datetime() docstring no longer says a parsed date cannot fail in any output: dateutil accepts partial dates that PostgreSQL may reject, which is contained as PostgreSQLError. The _reason_text() docstring says a dict with child elements gives None. Refs GHSA-4272-4r8g-6c5h Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Describe mailsuite 2.3.5's address group handling in the changelog The final mailsuite 2.3.5 no longer rejects an address header by its comma count; its parse_email() removes RFC 5322 group syntax from address header values over 8 KiB before parsing them. The boundary limit counts lines that are the boundary of an open multipart. parsedmarc's call with the default limits is unchanged. Refs GHSA-qcc2-4x3v-v4g7 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test the keep-alive call of the extracted record loop _parse_report_records() holds the record loop moved out of parse_aggregate_report_xml(); its keep-alive branch had no test. Refs GHSA-p85v-578x-3wcf Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test a policy override type with child elements With XML attributes dropped at parse time, a dict reaches _reason_text() only for an element with child elements; the test pins its None result and the CSV's "none". Refs GHSA-4272-4r8g-6c5h Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Check plain-string contact-info and mx-host for lone surrogates The surrogate check covered the string fields and string lists, but a contact-info or mx-host given as one string took a branch that skipped it, and a lone surrogate there still made the stdout print raise. Refs GHSA-4272-4r8g-6c5h Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Say which sample headers the failure document leaves out The GHSA-qpcg changelog bullet said every sample header stays in _source, but the failure save leaves out a From, To or Reply-To header that holds no address, as the Elasticsearch and OpenSearch pages say. Refs GHSA-qpcg-29vr-jwm3 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Keep sender-derived numbers out of the date range message The rejection message printed the report's span in days, so an <end> of thousands of digits put a number of thousands of digits into the exception text and the log. It now says only that the range is negative or longer than MAX_REPORT_SPAN_DAYS. Refs GHSA-p85v-578x-3wcf Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Store every string-typed aggregate field as a string or null Dropping attributes did not cover child elements: <version><x>1</x></version>, <p><x>1</x></p> or <p>none<x/></p> still reached the parsed report, and the Elasticsearch and OpenSearch documents, as a dict, and the first such document mapped the field as an object. _scalar() now makes each field the schema types as a string a string (an element's own text) or None, applied by _scalarize_report() to version, the report_metadata strings and every policy_published child, and by _parse_report_record() to source_ip, disposition, dkim, spf, the identifiers and every auth_results string. A <count> with no text of its own takes the ValueError path of a non-numeric count. _drop_xml_attributes() stays, so a field missed here still loses its attribute keys. The <email> dict unwrap is gone, since the field can no longer be a dict; a text-only report_metadata still raises the AttributeError that reports a missing section. Comments that described attribute dicts now say the dict shape comes only from child elements. The namespace test, which the new code could not fail, is replaced by one that detects RFC 9990 through an attributed np field. Tests walk the to_dict() of a mocked Elasticsearch and OpenSearch save and allow lists and objects only in the known object fields, so a scalar field added later is covered too. Refs GHSA-qpcg-29vr-jwm3 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Record a closed stdout pipe as an output error and fix two comments The standard-output guard in process_reports() caught only UnicodeEncodeError, so a closed pipe (BrokenPipeError, an OSError) still ended the run; it now records both as a "Standard output" output error. _reason_text()'s docstring said a dict gives None because the element has no text of its own, but mixed content (<type>forwarded<x/></type>) gives the text beside the children; the docstring now says what the code does, and a test pins it. The comment above the reason normalization no longer describes attribute dicts, which no longer reach it. Refs GHSA-4272-4r8g-6c5h Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test the normalization limit at its boundary and reword the index cap The suite passed with the limit's <= changed to < and with _days_touched()'s ceiling changed to a floor. New tests: 1,000 records over 250 days (exactly MAX_NORMALIZED_RECORDS) are split; 683 records over 366 days (249,978) are split and 684 (250,344) are not; 682 records over 366 days starting 1 s after midnight touch 367 days (250,294) and are not split. Each mutant was run against these tests and fails: the < mutant fails the exact-limit test, the floor mutant the after-midnight test. The Elasticsearch and OpenSearch pages now say the index cap applies when a report's records would use more than 31 dated indexes, which is what it counts (with monthly_indexes the span limit keeps a report under it). Refs GHSA-p85v-578x-3wcf Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Match the tests and changelog to mailsuite 2.3.5's final check mailsuite 2.3.5's check_message_limits() now parses the message with the email package's own feed parser under compat32 and counts the parts it creates (each message/delivery-status block among them), their nesting depth and its boundary tests, then limits header field length and count on the parsed tree; the limit names changed. The over-limit failure samples now trip max_parts, and the deeply nested poison message max_depth; the tests assert those texts. The GHSA-qcc2 changelog bullet describes the final check, the epilogue mail-parser parses again, and the changes that affect only mailsuite's own parse_email(). Refs GHSA-qcc2-4x3v-v4g7 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test a repeated policy_published and note mixed-content behaviour No test failed when _scalarize_report() stopped coercing the fields of a repeated <policy_published> (the list case): with that mutant, a report with two policy_published elements and <p><x>1</x></p> puts a dict into published_policy.p. The parse test and the Elasticsearch and OpenSearch document-walk tests now include that report; each fails on the mutant. The changelog says that an element with text and a stray child element now yields its text (samples/aggregate/invalid_xml.xml gives header_from "bad" where it gave ""). AGENTS.md and the _normalize_result_word() and _scalarize_report() docstrings describe what runs now: attributes are dropped as soon as the XML is parsed, and _scalar() coerces the string fields, among them the RFC 7489 and RFC 9990 policy_published fields. Refs GHSA-qpcg-29vr-jwm3 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Coerce policy override reasons with the same rule as other strings _reason_text() turned a repeated <type> or <comment> into the str() of the list, while _scalar() turns every other repeated string field into None. One class of input now has one rule: the reason's type and comment go through _scalar(), so a repeated one is None ("none" in CSV), and _reason_text() is removed. The test and the GHSA-4272 changelog bullet say so. Refs GHSA-4272-4r8g-6c5h Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Test an aggregate <error> with a child element With attributes dropped and reasons coerced by _scalar(), only <error>, which may repeat, still reaches _text() with a dict; its branch had no test. An <error> with text beside a child element keeps the text, and one with no text is dropped. Refs GHSA-qpcg-29vr-jwm3 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Describe mailsuite's six message limits in the changelog mailsuite 2.3.5's check now counts every line of every header block (folded lines and lines the parser keeps only as defects included) and stops the parse early, and limits the total length of the address headers mail-parser parses to 262,144 characters. The GHSA-qcc2 bullet names the six limits. Refs GHSA-qcc2-4x3v-v4g7 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Render a report email's parts only where their text is read parse_report_email() did str(payload_obj[0]) for every part walk() visits, before the multipart/ continue. str() of a composite part renders its whole subtree, and walk() visits every level, so a nesting within mailsuite's limits rendered its leaf once per level: 98 nested multiparts around a 20 MiB one-line leaf took 26.6 s, and a chain of 99 message/rfc822 parts around a 10 MiB leaf 11.3 s. A part is now rendered only in the branches that read it; other message/* bodies are skipped, since walk() visits their parts. Both shapes now take under 0.5 s, and every sample under samples/failure/ parses to the same output. A feedback report's sample is taken from the first sample part only: a message/rfc822 nested inside the sample used to replace it, but a feedback report has one sample (RFC 6591 section 3.1). Multipart nesting alone no longer reaches the recursion limit, so the GHSA-qxwv test now reaches the recursion guard through a deeply nested sample, which is still rendered. The changelog describes this and the address headers mailsuite 2.3.5 counts (From, Sender, Reply-To, To, Cc, Bcc, Delivered-To, in every part; mail-parser parses all but Sender). Refs GHSA-qcc2-4x3v-v4g7 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parse aggregate XML without attributes and lower the node limit _drop_xml_attributes() rebuilt the parsed tree while the original was alive, and the counting wrappers of _LimitedExpatParser referred to the proxy, closing a reference cycle through the expat parser that kept xmltodict's tree alive until the cyclic garbage collector ran. Both xmltodict passes now use xml_attribs=False, so no attribute key is ever built (expat still hands the attributes to the start handler, so they are still counted: a test shows one element with 1,000 attributes is 1,001 nodes), _drop_xml_attributes() is removed, and the counts live in an _XMLCounts object the wrappers share, so a parse leaves no cycle (a test asserts gc.collect() finds nothing after one). Peak extra memory for 2,000,000 distinct sibling elements: +999 MiB before, +386 MiB after (master +391 MiB); for one element with 2,000,000 attributes: +1,274 MiB before, +445 MiB after (master +734 MiB). At the old limit of 5,000,000 nodes a report could still need about 3 GB. Measured after the change, the worst shape is distinct elements with text behind a malformed XML declaration (the lxml recovery path): 559 bytes per node, +533 MiB for 999,000 nodes and +1,023 MiB for 2,000,000; on the expat path about 220 bytes per node. MAX_XML_NODES is now 1,000,000, so a report at the limit needs at most about 550 MiB; the largest sample has 32,019 nodes (909 KB), and the limit is a report of about 28 MB. The constant's comment and the changelog state the bound. AGENTS.md describes the attribute handling as it now is, and says that <error>, which may repeat, goes through _text() and stays a list. Refs GHSA-q7gm-8cj9-94hr Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Qualify the mixed-content compatibility note to string fields An element with text beside a stray child element yields its text only for the fields the schema types as strings; a <begin> or <end> with mixed content is still rejected, as before. Refs GHSA-qpcg-29vr-jwm3 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Reject over-long XML tags before any parser reads them expat and libxml2 build a start tag's whole attribute list before they report the element, so the node counter only sees the attributes after they cost memory: one element with 4,999,000 attributes (56 MiB) took 5.25 s and +767 MiB before the node limit rejected it, and a single element is bounded only by the 100 MiB decompression cap. parse_aggregate_report_xml() now scans the decoded text once, before the first parse and so before the lxml recovery path too, and rejects a document in which any text between a "<" and the next ">" (or the end of the text) is longer than MAX_XML_TAG_LENGTH (65,536 characters). The scan uses no regex. It splits the text on ">" one 64 KiB chunk at a time, carrying the unfinished piece from its last "<": a single split of the whole text makes one string per tag, which peaked at +1,318 MiB (1.9 s) for 100 MiB of "<a/>"; the chunked scan needs about 2 MiB and takes 0.6 s on that text, and a test bounds its memory and covers a tag across a chunk boundary. The longest tag in the samples is 108 characters. The same shape is now rejected in under 0.1 s, with a tracemalloc peak under 200 MB in the test, behind a well-formed or a malformed declaration. Refs GHSA-q7gm-8cj9-94hr Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Render a report email's feedback-report part only once The message/* skip exempted message/feedback-report, which was rendered with str() every time walk() reached one: a chain of 99 nested message/feedback-report parts around a 10 MiB leaf passed mailsuite's check in 0.02 s and then took 11.6 s. A feedback report has one message/feedback-report part (RFC 6591 section 3), so, as with the sample, only the first is read and rendered; the chain now takes 0.56 s. The failure samples parse to byte-identical output. Refs GHSA-qcc2-4x3v-v4g7 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Bound attribute counts by their = signs and cap reports at 32 MiB XML allows a raw > inside a quoted attribute value, so attributes such as x=">" cut a tag into short pieces that pass the tag scan: 4,999,000 of them cost 5.61 s and +781 MiB, and 8,000,000 (98 MiB) 8.9 s and +1,215 MiB, before the node limit fired. Every attribute needs an =, so a document with more = characters than MAX_XML_NODES is now rejected in one str.count() pass, before the tag scan; the samples hold at most 3. The tag scan stays for long tags, and its docstring says it does not bound attribute counts. The stated memory bound was false: text per node is bounded only by the size of the report, so at the node limit with 80 characters per element (94 MiB) the recovery path reached +827 MiB. MAX_DECOMPRESSED_REPORT_SIZE falls from 100 MiB to 32 MiB (the node limit already means a legitimate report is at most about 28 MB, at the samples' 35 nodes per KB, and the largest sample is 909 KB), and parse_aggregate_report_xml() holds an uncompressed report to the same length, so the bound holds for every input. Measured at the cap, 999,000 distinct elements with 14 characters of text (31 MiB) need +587 MiB on the recovery path and +302 MiB on the expat path; the constant comment and the changelog state it. When the first parse fails, the exception's traceback kept the partial xmltodict tree alive while the recovery parse ran; it is cleared first (+603 to +587 MiB, and +263 to +241 MiB for 330,000 elements of 80 characters). A test shows the recovery path leaves the same 18 lxml helper objects for a document ten times larger, so no tree survives a parse there either. Refs GHSA-q7gm-8cj9-94hr Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Let the RFC 6591 feedback part win over legacy report text The guard that reads only the first message/feedback-report part tested feedback_report, which the legacy text/plain branch ("A message claiming to be from you has failed ... detected.") also sets, so a legacy text part followed by a real feedback-report part and sample now took the legacy part and never read the ARF, where master read the ARF. The guard now tests is_feedback_report, and reading the feedback-report part discards a sample a legacy part set before it. The same rule closes an older gap: a text/plain part inside the sample, which is the spoofed message's own text, could hold the legacy phrase and replace the report's Source-IP and its sample. Once a feedback-report part is read, the legacy branch is skipped; a legacy report has no such part. Tests cover both orders and the in-sample case; the failure samples parse to byte-identical output. Refs GHSA-qcc2-4x3v-v4g7 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Hold every report input to the size cap and free failed parses parse_report_file() kept the aggregate parser's exception, whose traceback holds the parser's frames and the parsed tree, while it tried SMTP TLS and then the email parser: a 31 MiB file at the cap cost +1,046 MiB there against +587 MiB parsing it directly. It now keeps only each failure's text and raises from a fresh exception of the relevant format, so the chain survives without the tree. A file that begins with "<" is not tried as JSON (json.loads() decoded it all) or as an email, one that begins with "{" is not tried as an email (an RFC 822 message begins with a header line), and text over the size cap is never handed to the email parser, which has none: a 200 MiB <x/> file reached +2,801 MiB in 4.6 s and now costs +232 MiB (reading the file) in 0.05 s. extract_report() reads an uncompressed report at most one byte past the cap instead of decoding it whole. The cap counted characters for text and bytes for compressed reports, so a non-ASCII report could be four times the cap in bytes: 999,000 elements of 14 emoji (31.2 Mi characters, 71 MiB of UTF-8) cost +649 MiB. _exceeds_size_cap() measures text as UTF-8 (ASCII by length, other text 1 MiB of characters at a time, without a full copy), and bytes are checked before they are decoded. Clearing e.__traceback__ inside the except block did nothing on Python 3.10, which keeps the handled exception's traceback while the handler runs. The lxml recovery now runs after the except block, in _recover_xml(), so the first parse's frames and partial tree are unreachable when it starts on every supported Python; a test holds a weak reference to the first parse's counter and fails on the old code under Python 3.10.19 and, with the clearing removed, under 3.14. The changelog's examples are re-measured under the 32 MiB cap, and the test docstrings cite the same figures. Refs GHSA-q7gm-8cj9-94hr Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Skip the parts inside a failure report's sample Once the sample part was taken, walk() still visited its descendants, and they reached the SMTP TLS and base64 attachment branches: a sample whose spoofed message carried an SVG or zipped HTML attachment made the email rejected ("Missing field: 'feedback'", "Unable to parse"), and a gzipped aggregate report or a tlsrpt+json attachment inside it was returned as that report instead of the failure report. The sample is the reported message, so after it is taken every part inside it is skipped (by the id() of each part its walk() yields). Tests cover SVG, zipped HTML, JSON, gzipped aggregate XML, tlsrpt+json and PDF attachments; the failure samples parse to byte-identical output. The Bug fixes bullet also says that a legacy text part followed by a feedback-report part with no sample after it is now invalid, with a test. Refs GHSA-qcc2-4x3v-v4g7 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Cap SMTP TLS reports and test the format skips parse_smtp_tls_report_json() decoded and json.loads()-ed a report of any size; only the gzipped path was capped, and 60 MiB of "[]," cost +1,565 MiB. It now rejects bytes or text over MAX_DECOMPRESSED_REPORT_SIZE first, as InvalidSMTPTLSReport, so every report type is held to the cap. parse_report_file() names the actual reason it skips the email parser (the leading "<" or "{", or the size cap) rather than a combined one, and a size message for bytes no longer says "of UTF-8". New tests kill the mutants the review found surviving: removing the "<" skip for JSON, narrowing the email skip to "<", the bytes check >= for >, and removing the SMTP TLS cap. The constant comment and the changelog state the memory at the cap as measured on the current code: +345 MiB on the lxml recovery path and +302 MiB on expat parsing the text directly, +500 MiB and +452 MiB through parse_report_file(). The changelog says only the exception's cause changed for files skipped by format, not the message. Refs GHSA-q7gm-8cj9-94hr Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Skip every sample candidate and correct the stated measurements sample_parts held only the first sample candidate's parts, so a later message/rfc822 (or one after a text/rfc822-headers sample) was dropped as a sample but its parts were still walked, and a gzipped aggregate report inside it was returned in place of the failure report. Every candidate's parts are now skipped. Tests cover both shapes, and a test that a gzipped aggregate report beside the sample is still returned pins the rule (inside the sample: skipped; beside it: read) and fails when the set is built from the whole message. parse_report_file() no longer builds email reasons for content that begins with "<" or "{", which its message never shows, and the size reason reads "Invalid report email: the report is larger than 32 MiB". The memory figures are re-measured in a fresh process with the input read from disk before the baseline: +399 MiB on the recovery path and +338 to +355 MiB on expat for the 31 MiB shape, +1,505 MiB for 60 MiB of JSON before the SMTP TLS cap; the constant comment, the changelog and the test docstrings state them. RFC 6591 section 3.1 is cited for the sample's place, and application/json is named among the attachments that made a failure report invalid. Refs GHSA-qcc2-4x3v-v4g7 Refs GHSA-q7gm-8cj9-94hr Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Scale the timed tests' bounds to the machine running them The mailsuite fix's first CI run on GitHub's shared runners failed six timed tests: the suite ran four to six times slower there than on a workstation, and checks doing real work took longer than their fixed bounds. Several bounds here have far less margin (0.2 s on a test that takes 0.18 s whole), so they would fail the same way. tests/timing.py adds budget(seconds), which measures a fixed reference parse twice just before the timed call and multiplies the bound by the slowdown against a reference machine; a faster machine keeps the written bound. Every timed assert now compares against budget(<written seconds>) computed before the timer starts. No written bound changed and no assert was removed.

With [smtp] ssl = False (the default) or [imap] ssl = False, mailsuite upgraded the connection only if the server's plain-text EHLO/CAPABILITY reply advertised STARTTLS, and otherwise authenticated in plain text. An on-path attacker who stripped STARTTLS received the credentials and the emailed results (CWE-319). - Require mailsuite >= 2.3.4 (GHSA-2x4j-7g3q-wr6f), whose default refuses to authenticate over a connection that was not upgraded. - Add [imap] and [smtp] starttls (unset = require STARTTLS; false = explicit plain-text opt-out, for loopback servers such as DavMail), with a startup warning when the opt-out is set and ssl is False. - Add a starttls argument to email_results(). - Document both options; set starttls = False in the DavMail example.

Fix aggregate report deduplication across policy domains (#934)
* Fix aggregate report deduplication across policy domains Scope aggregate-report identity to the reporting organization, Report-ID, and policy domain, matching RFC 9990 section 3.5.1. Encode the fields as a JSON array and compare ASCII domain letters without changing returned report data. Preserve accepted empty-domain reports and save-confirmed cache semantics. Add real MIME/mbox and dry-run Maildir regressions for distinct domains, same-domain repeats, shared configurations, boundary collisions, parallel parsing, and false/raising save callbacks. The implementation and tests were prepared with AI assistance, including a separate review of the scoped changes and test evidence. * Share the domain-scoped dedup key with the CLI direct-file path Responds to Copilot review on #934: the CLI's direct-file path still wrote `{org_name}_{report_id}` keys into the same seen-aggregate-report cache that the mbox/mailbox classifier now reads with a JSON [org, report_id, policy_domain] key, so a report passed both as a file and inside an mbox in one run was saved twice, and direct files from one reporter sharing a Report-ID for different domains (RFC 9990 §3.5.1) were still collapsed. Extract the key into `_aggregate_report_dedup_key()` and use it from both paths; the direct-file path now writes through `parser_config.seen_aggregate_report_ids` like the mbox path. Adds end-to-end `_main()` regression tests for mixed file+mbox input and for domain-scoped direct-file dedup.

* Fix three security advisories (DOCTYPE amplification, poison mailbox message, byte-length filenames) GHSA-m47j-wp78-fqjg: reject any DOCTYPE in aggregate report XML. An internal subset's <!ATTLIST> default attributes are applied by expat to every matching element, so 64 KB of XML (K=1000, N=10000) took 4.0 s and 1.4 GB here. xmltodict now gets an expat shim whose parsers raise on StartDoctypeDecl; the lxml recovery path checks docinfo and serializes only the root element. GHSA-qxwv-2vwj-v828: parse_report_email() now raises only ParserError subclasses (HeaderWriteError / RecursionError from re-serializing a part used to escape). Content errors raised while fetching a message (email.errors.MessageError, RecursionError) are returned as ParserError and the message is disposed of as invalid; transport errors still propagate. A failed invalid-message move/delete is logged instead of aborting the batch, because mailsuite's Maildir move_message() re-serializes the message too. mbox reads use get_bytes() instead of the re-serializing get_string(). GHSA-j53g-34vj-g25q: get_filename_safe_string() bounds names to 100 UTF-8 bytes as well as 100 characters; filesystems limit a name to 255 bytes, so 84 CJK characters + ".eml" failed with ENAMETOOLONG. Reported by helixnebulatech. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Address review: recursion margins, mbox wording, DOCTYPE check order - Nest the RecursionError poison 400 levels deep (POISON_NESTING_LEVELS) instead of 250: the smallest failing depth is ~247 from a shallow stack, 245 in a fork worker and ~222 at +100 frames, so 250 left a margin of a few levels. The shallow case uses 50 levels and now asserts InvalidDMARCReport ("is not a valid report"); the deep case asserts "recursion" in the message. - Poison-loop tests skip a benign poison per message (continue) and assert at least one poison was exercised, so they cannot pass vacuously. - lxml recovery: check for a DOCTYPE before serializing the root, and comment why the str() around tostring(encoding="unicode") stays (pyright, no lxml stubs). - CHANGELOG: describe what the walk actually serializes, drop the depth-dependent 245 figure, and say plainly that an mbox run still stops at such a message, now with a ParserError naming it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Make the Maildir poison-message test interpreter-independent Whether MaildirConnection.move_message() can store the control-character message depends on the interpreter: upstream CPython (3.12.9) runs the CVE-2024-6923 generated-header check only in the text Generator used by as_string(), so mailbox.Maildir.add()'s BytesGenerator stores it, while Ubuntu's patched 3.12.3 also checks in BytesGenerator._write_headers and the move fails. The deeply nested message fails the move everywhere. The test now decides per message, by trying the same Maildir round trip, whether the message lands in Archive/Invalid with no mailbox error logged or stays in INBOX with the move error logged; both branches assert the batch completed with the aggregate archived. CHANGELOG and the _dispose_invalid_message docstring now say which messages stay put.

Fix ReDoS in failure-report, schema-tag, and timestamp regexes (11.0.4) (#921)
Three regular expressions that run on attacker-controlled input backtracked super-linearly (CWE-1333): GHSA-7grx-mj6g-qxmc (affects 8.2.0 through 11.0.3, reported by mjatin2007): text_report_regex, used by the Exim/cPanel plain-text failure-report fallback, was \s*([a-zA-Z\s]+):\s(.+). The leading \s* and the \s inside the class overlap and the pattern is unanchored, so a whitespace run is retried from every offset and every split: cubic, about 8x per doubling (400 spaces 0.06 s, 1600 spaces 3.3 s on CPython 3.12). A ~100 KB message would stall the watch loop for days and be re-parsed after every restart. The pattern is now anchored to a line start with disjoint classes. GHSA-4h9r-c435-j834 (affects 4.1.7 through 11.0.3, found while auditing every regex in the package): xml_schema_regex was </??xs:schema.*>, whose greedy .*> rescans to end of line for every <xs:schema occurrence: quadratic, 1 MB in 19 s. It runs on every attachment that decodes to "<" after extract_report() has inflated it up to the 100 MiB cap, which 194 KB of gzip reaches. Now </?xs:schema[^<>]*>. This also fixes the greedy match deleting a minified single-line report from the schema tag to the last ">" on the line. human_timestamp_to_datetime() stripped RFC 5322 comments with \s*\(.*\)\s*, quadratic on whitespace (200,000 spaces 18.6 s) and reached through every Date header; filed as a bug fix because MTAs cap header size. Comments are now removed by a depth-counting scan, which is linear and handles the nested comments and quoted-pairs RFC 5322 section 3.2.2 allows (a character-class regex would have regressed them). Adds regression tests sized so the old patterns fail the time bound in minutes rather than hanging CI, a "Regular expressions on untrusted input" section in AGENTS.md, and the 11.0.4 changelog and version bump.

Fix blank SMTP TLS failure-detail fields crashing saves; read RFC 8460 additional-information (11.0.3) (#916)
* Treat blank SMTP TLS failure-detail fields as absent; read RFC 8460 additional-information
Some reporters send optional failure-details fields as empty strings
(e.g. "sending-mta-ip": "" on sts-policy-fetch-error). The parser copied
them verbatim, so the PostgreSQL save failed on the INET columns
("invalid input syntax for type inet") and the Elasticsearch/OpenSearch
saves failed Ip() validation, discarding the whole report. Blank or
whitespace-only optional values are now omitted.
RFC 8460 section 4.4 names the URI key "additional-information"; the
parser only read "additional-info-uri" (the schema's value placeholder),
so conformant reports lost the URI. The RFC key is now read, with the old
key kept as a fallback.
Bump version to 11.0.3.
Closes #915

fix: never close a caller-supplied file object in parse_report_file/extract_report (#909)
parse_report_file() and extract_report() both closed a file-like object the caller passed in once they finished reading it (on the success path only). A function must not close a handle it did not open: the caller may still want to seek(0) and retry, log tell(), or reuse the handle. - parse_report_file(): the caller-supplied-object branch no longer calls .close(). A path is still opened and closed via `with`; bytes are still wrapped in a function-owned BytesIO that the function closes. - extract_report(): the seekable-stream branch previously aliased the caller's stream into `file_object` and then unconditionally closed it in `finally`, on the success path and on the exception path alike. An `owns_file_object` flag now tracks whether `file_object` is a buffer this function created (str/bytes input, or a copy made from a non-seekable caller stream) versus an alias of the caller's own seekable stream; only the former is closed. - parse_aggregate_report_file() forwards its input straight to extract_report() and does no closing of its own, so it inherits the fix; its docstring now says so and points to extract_report()'s for the exact post-call position. Both extract_report()'s and parse_report_file()'s docstrings now state the contract explicitly. extract_report()'s docstring initially claimed a successful call leaves a seekable caller stream "positioned at 0" and described the seek(0) as seeking "back" to the caller's prior position; neither is true. The unconditional stream.seek(0) after reading the 6-byte header runs regardless of where the caller's stream was positioned, and the subsequent content read (member/gzip/text) advances the stream again, so a successful call typically leaves it at EOF, not 0 (measured: XML 866, gzip 428, zip 901/974). The docstring now matches parse_report_file()'s wording: left open, positioned wherever the function's own reads left it. Added testParseReportFileLeavesCallerHandleOpenOnSuccess, testExtractReportLeavesSeekableCallerStreamOpen (success path), and testExtractReportLeavesSeekableCallerStreamOpenOnError (exception path, completing the "never closed on success or failure" claim, which had gone untested on its exception half) -- asserting real BytesIO `.closed` state and, for the success cases, that the handle is still readable after seek(0). All three fail against the pre-fix code; verified with `parsedmarc.__file__` that the import resolved to this worktree's package, not a stale venv install, before trusting the failure/pass results. Updated testParseReportFileLeavesCallerHandleOpenOnReadError's docstring, which described the old "closed on success" behavior as intentional. Also added testParseAggregateReportFileLeavesCallerStreamOpen: the contract paragraph added to parse_aggregate_report_file()'s docstring was previously untested through that entry point -- its existing stream-based tests only exercise extract_report() and parse_report_file() directly, while parse_aggregate_report_file() itself was only ever called with bytes. The new test passes a caller-owned BytesIO through parse_aggregate_report_file() and asserts it is still open after both a successful parse and an InvalidAggregateReport raised on garbage content. It fails against the pre-fix code (AssertionError: True is not false on the success-path assertion); verified via `parsedmarc.__file__` that the import resolved to this worktree's package before trusting the result. CHANGELOG: added an Unreleased/Changes entry (behavior change for library callers, naming all three affected functions) and corrected the existing Unreleased/Bug fixes entry for parse_report_file's path-close fix, whose closing sentence about caller-supplied objects this PR makes false and whose cross-reference to "the Changes section below" pointed the wrong direction (Changes is above Bug fixes).

chore: address CodeQL code-quality findings (no behavior change) (#900)
- py/empty-except: add a short comment to each of the 10 flagged
`except <Type>: pass` blocks explaining why swallowing the
exception is correct there (best-effort cleanup/close, or
intentional fall-through to the next report format).
- py/unnecessary-lambda: replace `map(lambda x: parse_email_address(x), ...)`
with `map(parse_email_address, ...)` at the 5 flagged sites in
parsedmarc/utils.py; parse_email_address takes exactly one
positional argument, so this is behavior-preserving. Ran
`ruff format` afterward, which collapsed 3 of the now-shorter
calls onto single lines.
- py/imprecise-assert: replace `assertTrue(a > b)` / `assertTrue(a >= b)`
with `assertGreater(a, b)` / `assertGreaterEqual(a, b)` at the 9
flagged test sites; none carried a custom assertion message.
- .vscode/settings.json: drop three cSpell whitelist entries that are
pure misspellings ("passsword", "httpasswd", "unparasable") and
appear nowhere else in the tracked tree, so a recurrence of the typo
they used to hide (see #888) would be caught again. The correctly
spelled "htpasswd" and "unparseable" entries are untouched.
Verified clean: ruff check, ruff format --check, pyright (0
errors/warnings), and pytest tests/ (989 tests collected and passing
before and after, GITHUB_ACTIONS=true).

Fix file descriptor leak in parse_report_file (CodeQL py/file-not-closed) (#899)
parse_report_file's path branch opened the file with open(file_path, "rb") and then, on a later line, called file_object.read() followed by file_object.close() with no exception handling between them. An exception from read() (e.g. an OSError from the underlying storage) skipped close() and left the descriptor to be released only when Python's garbage collector eventually finalized the object, rather than closed deterministically (CPython's io.IOBase.__del__ closes an unclosed file on finalization: https://docs.python.org/3/library/io.html). This is the pattern CodeQL's py/file-not-closed query flags, found in a local code-quality scan. The path branch now opens the file with a `with` block, so the handle is closed on both the success and exception paths. The fix is scoped to only that branch: a BytesIO created internally from bytes/bytearray/memoryview input, and a file-like object supplied by the caller, are both closed only after a successful read and left open if read() raises, exactly as before this commit. Widening that to close a caller-supplied handle on the exception path too would be a behavior change outside this fix's scope. Also closes tests/test_init.py's TestGetDmarcReportsFromMailboxMaildir ._deliver, which did open(source, "rb").read() with no close() at all; it now uses a `with` block. Two regression tests cover the narrowed contract: - testParseReportFileClosesHandleOnReadError patches builtins.open (the SDK boundary) with a fake handle implementing the context-manager protocol, and asserts close() is called when read() raises. Verified against origin/master's version of parsedmarc/__init__.py: the test fails with "AssertionError: False is not true" (close was never called), confirming it catches the leak. - testParseReportFileLeavesCallerHandleOpenOnReadError passes a caller-supplied fake handle directly as input_ and asserts close() is NOT called when read() raises. Verified against a naive whole-block try/finally (wrapping close() around all three branches instead of only the path branch): the test fails with "AssertionError: True is not false" (close was called), confirming it catches the scope widening this PR must avoid.

11.0.1 release: harden failure-report sample filenames and cap decompressed report size (#895)
* Harden failure-report sample filenames and cap decompressed report size Fixes the two open security advisories. GHSA-c284-w5m6-jhjm (path traversal, affects 9.0.6 through 11.0.0): save_output() named each failure report's message sample after the sample's Subject header, falling back to the raw subject whenever sanitizing it produced an empty string. A subject of only path separators and dots -- "../../../" or "/" -- sanitizes to "", so the raw value reached os.path.join() and the .eml landed outside the samples directory or at an absolute path. That subject comes from a message that failed authentication, so any sender a monitored mailbox accepts controls it. The name is now sanitized at write time and falls back to "sample", and the caller-supplied filename_safe_subject key is no longer trusted. get_filename_safe_string() also strips NUL (which would otherwise make open() raise ValueError: embedded null byte and hold back the whole mailbox batch), truncates before stripping trailing characters, and strips trailing spaces along with trailing dots, since Windows drops both when creating a file; its docstring now states the guarantees callers depend on. GHSA-43qf-f35w-2x4r (unbounded decompression, affects all versions through 11.0.0): extract_report() inflated gzip with one unbounded zlib.decompress() and read zip members with an unbounded .read(). The attachment's content is chosen by its sender, and deflate reaches about 1000:1 on degenerate input, so a 100 KB attachment inflated to 100 MB with a ~209 MiB peak. Extraction now stops at MAX_DECOMPRESSED_REPORT_SIZE (100 MiB) and raises ParserError. The gzip path moves to a zlib.decompressobj() bounded by max_length, which does not raise on a stream that ends early the way the one-shot call did, so the helper checks decompressor.eof itself; a stream with trailing bytes after the gzip member still extracts, matching the old behavior. Both behaviors were observed against the unmodified code first and are pinned by tests. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * Strip NUL from CSV fields so Python 3.10's csv writer accepts them Python 3.10's csv writer raises _csv.Error: need to escape, but no escapechar set on any field containing NUL (CPython issue 97503, a 3.10 regression fixed in 3.11+). Failure report text fields (subject, user agent, authentication results, addresses, etc.) come from untrusted mail, so a NUL byte in one made parsed_failure_reports_to_csv() -- and therefore save_output() -- raise on 3.10, which the CLI's except (OSError, ValueError) around save_output does not catch. NUL is now stripped from every CSV field on all Python versions via a shared _csv_safe() helper, applied in all three CSV writers, so output is identical regardless of interpreter version.

Make the output and mailbox integrations optional extras (#888)
* Make the output and mailbox integrations optional extras (#883) Breaking change for the next major release: pip install parsedmarc now installs the parsing core plus a working core CLI (file, IMAP, Maildir, and mbox input; CSV/JSON, Splunk HEC, webhook, and syslog output). Everything else moves behind an extra: elastic, opensearch, kafka, s3, gelf, loganalytics, msgraph, and gmail, joining the existing postgresql extra, with an umbrella [all] that deliberately excludes postgresql (psycopg's binary wheels do not exist on every platform, so parsedmarc[all] must never fail to install there). cli.py imports the six SDK-dependent output modules behind the #884 TYPE_CHECKING/try-except guard; a configured section whose extra is missing fails fast with a ConfigurationError naming the section and the exact pip install command — including the msgraph and gmail_api mailbox sections (detected via parsedmarc.mail's placeholder classes) and postgresql (checked before the constructor so the startup retry loop does not retry a missing dependency for a minute). The Azure/kiota Graph error types fall back to never-raised sentinel classes. The Docker image installs [all,postgresql], so container users see no change. CI lint installs [build,all,postgresql]; the unit-test job installs [build,all], deliberately without postgresql so test_postgres.py's absent-psycopg arm stays exercised. The never-imported dateparser dependency is dropped in favor of declaring python-dateutil, which utils.py actually imports; pytz moves to the build extra for the one test that uses it. Verified live: a no-extras wheel install imports, parses samples, and reports the install hint for each gated section; a [all] install restores every integration; the Docker image builds with every SDK importable. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Patch psycopg presence in the PostgreSQL CLI wiring tests CI's unit-test job deliberately installs [build,all] without the postgresql extra, so parsedmarc.cli.postgres.psycopg is None there and the new missing-extra presence check correctly made _main exit 1 before the wiring under test ran. The tests simulate the SDK being available (PostgreSQLClient is mocked at the SDK boundary), so the module-level psycopg handle is now patched present in setUp. Verified against a simulated psycopg-absent environment as well as the local full install. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Address Copilot review: narrow guards to ModuleNotFoundError, fix docs - The optional-integration and Graph error-type import guards now catch ModuleNotFoundError instead of ImportError, so only a genuinely absent package reads as a missing extra; a broken-but-present SDK fails loudly with its real error instead of masquerading as one. The test blocker raises ModuleNotFoundError accordingly — the exact exception a missing package produces. - _missing_extra_hint docstring no longer calls every gated integration an output module (it also serves the msgraph/gmail_api mailbox sections). - Fix the pre-existing passsword typo in usage.md's kafka section; the INI key the code reads is password (cli.py _parse_config). Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Quote extras specs in copy-paste install commands From Copilot's second review round: zsh treats an unquoted .[build,all] as a glob and fails with 'no matches found', so the commands shown in AGENTS.md, CONTRIBUTING.md, dashboards/README.md, and the bootstrap script's comment are now quoted. The CI workflows keep the unquoted form: they run under bash, which passes unmatched globs through literally. The suggestion to change the 'Choosing what to install' heading level was rejected — it is a subsection of 'Installing parsedmarc', matching the file's existing hierarchy. Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix upgrade command in the changelog * Documentation review: accuracy, spelling, grammar, and clarity pass A full prose review of docs/source, README, CONTRIBUTING, and the dashboards README, with every accuracy claim verified against the code before changing it. Highlights: - usage.md: documented six missing [general] options (the CSV/JSON filename options, prettify_json, normalize_timespan_threshold_hours), the required kafka smtp_tls_topic, [imap] timeout/max_retries, and the postgresql env-var prefix; corrected the maildir_path default (None, not INBOX — cli.py Namespace defaults), the mailbox check_timeout option name, the systemd restart interval (RestartSec is 5m), and merged the duplicate silent entry; quoted every copy-paste extras spec for zsh safety. - elasticsearch.md: fixed an invalid openssl command (rsa:4096 -nodes), the dashboards filename (opensearch_dashboards.ndjson, matching the file the link serves), and assorted grammar. - davmail.md: the service-enable command now enables davmail.service (was parsedmarc.service — a copy-paste error that left DavMail unenabled), plus a view typo and DavMail capitalization. - output.md: the example schema reference is RFC 7489 Appendix C (7480 is RDAP). kibana.md: SPF relies on the SMTP envelope, not session headers (RFC 7208). dmarc.md: DKM -> DKIM. - README: the intro now also names the OpenSearch/Grafana stack, matching the feature list. CONTRIBUTING: pre-PR checks now include ruff format --check and pyright, matching CI's lint job. - dashboards/README: the service table and seed description now include the PostgreSQL backend the compose stack runs. Sample data blocks, the CLI-help mirror block, and released CHANGELOG entries were deliberately left untouched. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Docstring review: accuracy, spelling, grammar, and clarity pass Every docstring in parsedmarc/, parsedmarc/mail/, the maps maintainer scripts, and the test suite reviewed with each claim verified against the code it documents. Text-only — no behavior changes. Highlights: - Copy-paste errors corrected: parsed_smtp_tls_reports_to_csv and splunk/loganalytics save functions described aggregate or failure reports they do not handle; LogAnalyticsException claimed to be an Elasticsearch error. - Docstring/behavior mismatches: parse_report_email's report_type enumeration omitted smtp_tls; parse_failure_report typed msg_date as str (it is datetime); strip_attachment_payloads claimed payloads are replaced with None (the key is deleted); kafkaclient's failure and SMTP TLS savers claimed per-record slicing while sending the whole list in one message (docstrings now describe reality — whether slicing was intended is flagged for follow-up); the postgres savers claimed to take parse_report_file's return value but receive the inner report dict; elastic/opensearch save functions' Raises listed only AlreadySaved. - None-as-semantic-state documented where missing (get_base_domain, get_ip_address_country), enumeration completeness fixed (get_ip_address_info's 9 result keys, maps script outputs, TSV columns), and the stale 44-industry-types count corrected to the 46 the authoritative README list defines. - Test docstrings aligned with what the tests actually assert, including two that overstated coverage of the elastic/opensearch address-list tests. - Two argparse help strings fixed: file_path now names SMTP TLS report files alongside aggregate and failure, mirrored into usage.md's CLI-help block; --offline's doubled spaces removed (rendered help unchanged). - elasticsearch.md's security claim corrected against Elastic's docs: security is enabled and auto-configured on first startup since 8.0 (not "8.7 secure mode"), so the settings are verified, not hand-written.

Decode failure report MIME parts per their Content-Transfer-Encoding (#885)
* Decode failure report MIME parts per their Content-Transfer-Encoding Fixes #882. parse_report_email() read every MIME part's payload without asking the standard library to decode it, leaving any transfer encoding in place: - A quoted-printable text/rfc822-headers sample part kept its RFC 2045 §6.7 soft line breaks, which split long headers without RFC 5322 folding whitespace. The sample's From header became unparseable and, with no Reported-Domain field in the report, the whole failure report was discarded with "TypeError: 'NoneType' object is not subscriptable". - A quoted-printable message/feedback-report part parsed "successfully" with silently corrupted values (e.g. "dmarc=3Dfail"). A new _decode_mime_payload() helper decodes quoted-printable and base64 parts only, applied to the message/feedback-report and sample branches; all other branches still receive the raw payload because they do their own base64/magic-byte handling. Parts with a 7bit/8bit/absent CTE are returned as-is: the message is parsed from a str, so compat32's get_payload(decode=True) would round-trip the already-correct text through raw-unicode-escape and corrupt non-ASCII characters. For nested message/* parts (the stdlib nests every message/* subtype, so decode=True returns None), the encoding is undone by hand, including removing the header/body separator the Generator inserts when the still-encoded text stops looking like headers mid-block (MissingHeaderBodySeparatorDefect) — without that, values were truncated at the first soft line break. Also fixed in the process, per the same-PR rule for bugs found while writing tests: - feedback_report_regex captured the CR of CRLF line endings (RFC 5322 §2.1 mandates CRLF; re.MULTILINE's "$" matches before the LF, not the CR). Previously masked because the base64 branch decoded through a bytes repr and stripped literal "\r" escapes. - A report with no Reported-Domain field and no parseable sample From domain now raises InvalidFailureReport with a clear message instead of the opaque TypeError; reported_domain is a required str in the FailureReport contract (types.py) consumed unconditionally by the Elasticsearch/OpenSearch outputs, so defaulting it to None is not an option. InvalidFailureReport raised inside parse_failure_report() now propagates without the "Unexpected error:" re-wrap. CLI output over the whole sample corpus is byte-identical before and after (PYTHONHASHSEED=0, n_procs=1). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Use RFC 5322 header folding instead of implicit string concatenation The hand-built test message's long Content-Type header was split across two adjacent string literals inside a list, which reads like a missing comma (flagged by code review). Fold the header with a tab continuation line instead — truer to the wire format the builder exists to produce. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Reword test builder docstring to claim only what it does Copilot review: the builder joins lines with "\n" and embeds CRLF inside the feedback-report block, so it does not preserve on-the-wire bytes exactly. What matters for the test is only that the non-ASCII sample text stays unencoded; say that instead.

Don't archive/delete mailbox messages until output destinations confirm the save (#863)
* Don't archive/delete mailbox messages until output destinations confirm the save (#242) get_dmarc_reports_from_mailbox() gains a keyword-only save_callback, invoked once per fetched batch before any message is deleted or moved. A False return (or an exception) marks the batch unsaved: its messages stay in the reports folder for retry, and the aggregate-report dedup keys staged for that batch are dropped so the retry reparses instead of skipping. watch_inbox() passes its callback through as save_callback, so watch mode gets the same protection. To bound duplicate delivery to destinations that don't deduplicate, a new [mailbox] max_unsaved_retries option (default 2) caps retries: a message whose batch has failed the initial attempt plus that many retries moves to {archive_folder}/Unsaved -- never deleted, whatever the delete options say. Counts are process-local, so the cap applies across watch-mode checks; one-shot runs retry indefinitely, which is the safe direction. A raising callback (the CLI's, under fail_on_output_error) is counted against the cap the same way before the exception is re-raised, since mailsuite's IMAP and Maildir watch loops swallow exceptions and keep checking. CLI: process_reports() now returns its output-error list and the mailbox_save_callback adapter feeds that verdict to the library; save_output() failures (the one uncaught destination) are recorded like every other sink's; file/mbox-derived reports are saved in a separate pass from mailbox batches so nothing is saved twice; the combined results fed to email_results() are filtered by index_prefix_domain_map explicitly, restoring the SMTP TLS filtering the emailed summary lost when saving moved into per-batch callbacks. Credit to @mkilijanek for the original approach in #823. Fixes #242 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Address automated review feedback on #863 - Keep a message's failure counter until its move to Unsaved actually succeeds. The counter was popped when the message was classified over-cap, before the move was attempted, so a failed move handed the still-in-place message a fresh set of under-cap retries and duplicate deliveries; now the next failed save classifies it over-cap again and re-attempts the move. Regression-tested at cap 1, where the reset would observably leave the message in the INBOX instead of moving it. - Use sys.exit(1) instead of the site-dependent exit() built-in in the two new ParserError handlers. - Close the sample files opened by the new Maildir tests via context managers. - Keep the docs' section-link text on one line and fix the adjacent pre-existing "a IMAP" typo. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Address Copilot re-review feedback on #863 - Document mailbox_save_callback's raise path: with fail_on_output_error it raises ParserError via process_reports() instead of returning False, and the library counts that as an unsaved batch too. - Use str(error_) instead of error_.__str__() in the new File output handler. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Reject negative max_unsaved_retries with a ValueError The option is user-configurable (INI/env/kwarg); a negative value silently behaved like 0. Both get_dmarc_reports_from_mailbox() and watch_inbox() now validate it at the door alongside the existing test/delete guard. watch_inbox() validates before entering the watch loop, because a ValueError raised inside a check would be swallowed and endlessly retried by the IMAP and Maildir backends' per-check exception handling instead of surfacing. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix two pre-existing bugs surfaced by review of #863 - MAGIC_JSON was b"\7b" -- the octal escape \7 (BEL) plus a literal "b", not 0x7B, the "{" every RFC 8259 JSON object begins with -- so extract_report() rejected plain uncompressed JSON. Every in-tree caller pre-guarded with its own zip/gzip or "{" check, masking the dead branch; the practical impact was extract_report() as a public API and application/tlsrpt+gzip attachments whose payload is really uncompressed JSON. Now b"\x7b". - get_index_prefix() unconditionally indexed policies[0], while parse_smtp_tls_report_json() accepts a report whose policies list is empty -- an IndexError crash whenever index_prefix_domain_map was configured. An empty-policies report has no domain to map, so it is now treated as unmappable and excluded from prefix-mapped output. This code was moved into filter_smtp_tls_reports_for_index_prefix() by this PR, which widened its exposure to the email_results() path. Both regression tests were verified to fail against the unfixed code. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Rewrap the max_unsaved_retries docstring paragraph The ValueError sentence was inserted without reflowing, leaving a 112-character line in a docstring wrapped at ~76; ruff formats code, not docstring prose, so it slipped through lint.

Add per-report-type mailbox delete options (#858)
* Add per-report-type mailbox delete options (#256) Add four new [mailbox] options — delete_aggregate, delete_failure, delete_smtp_tls, and delete_invalid — each defaulting to the value of the overall delete option and individually overridable, so e.g. delete = True with delete_failure = False deletes processed aggregate and SMTP TLS report messages while archiving failure reports, and delete_invalid = False keeps unparseable messages in the Invalid archive subfolder for debugging. get_dmarc_reports_from_mailbox() and watch_inbox() gained matching bool | None keyword arguments (None = inherit from delete), resolved once up front; the delete/test mutual-exclusion guard now checks the effective per-type flags. The Gmail deletion-scope guard covers any effective flag and forces all five options off when the scope is missing. PARSEDMARC_MAILBOX_DELETE_* env vars work automatically. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Document per-type delete kwargs as bool | None with explicit inheritance Copilot review: the docstrings typed the four per-report-type delete parameters as plain bool, but None (the default) is the inheritance mechanism — a library caller couldn't tell from the docs that None, not False, means "inherit delete". Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Cover disposal error branches; scope the config= docstring claim Codecov flagged the delete-error handler in the new per-type disposal loop as the one uncovered patch line. Add two Maildir tests driving a backend whose first delete/move call raises: the error is logged, the affected message stays in the INBOX, and disposal continues to the next report type. The move-error branch gets the symmetric test from the same harness. Copilot review: the config= docstring paragraph claimed all keyword arguments listed above it are ignored when config= is provided, which now falsely included the four per-type delete options. Scope the claim to the parsing/enrichment arguments ParserConfig actually carries and state that mailbox-handling arguments always apply.

Centralize configuration handling with ParserConfig (#503) (#851)
* Centralize configuration handling with ParserConfig (#503) Add parsedmarc/config.py with ParserConfig, a frozen dataclass carrying every parsing/enrichment option plus the three shared caches (IP address info, seen aggregate report IDs, reverse DNS map). All eight public parsing/mailbox functions accept a keyword-only config= argument; when provided, the individual option keyword arguments are ignored in favor of the config's values, and every existing per-option keyword argument keeps working unchanged. The three hand-copied parse_kwargs dicts and the dns_timeout<->timeout rename chain are gone; the CLI builds one ParserConfig per run (rebuilt on SIGHUP) and passes it everywhere. Explicitly constructed configs own fresh isolated caches; dataclasses.replace() shares them; pickling drops cache contents and rebinds the unpickling process's module defaults, preserving the per-worker cache behavior of n_procs parallel parsing. The module globals IP_ADDRESS_CACHE / SEEN_AGGREGATE_REPORT_IDS / REVERSE_DNS_MAP remain, identity-preserved, as re-exports of the default caches. Bug fixes that ride along, each with a regression test: - One-shot mailbox runs now honor [general] dns_timeout/dns_retries; the CLI call site never forwarded dns_timeout, so the library's stray 6.0 default silently applied. - Lazily-triggered reverse DNS map loads (get_ip_address_info / get_service_from_reverse_dns_base_domain, including in n_procs workers) now thread psl_overrides_path/psl_overrides_url through to load_reverse_dns_map instead of clobbering operator-configured PSL overrides with the bundled defaults. - get_dmarc_reports_from_mailbox() and watch_inbox() dns_timeout defaults unified to DEFAULT_DNS_TIMEOUT (2.0s) from a stray 6.0, and normalize_timespan_threshold_hours to the float 24.0 used everywhere else. Closes #503 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Address CI and review feedback on #851 - Wrap the IMAPConnection example in usage.md so ruff format is clean over the docs code blocks (CI runs ruff format --check on the whole repo; the local runs were scoped to parsedmarc/ and tests/ and missed it). - Fix the pre-existing "URL ro a reverse DNS map" docstring typo in get_service_from_reverse_dns_base_domain, caught by Copilot on the adjacent hunk. - Import parsedmarc.config once, as an aliased plain import, in tests/test_config.py instead of mixing import and import-from of the same module (flagged by code quality scanning); the aliased module import also keeps pyright able to resolve the submodule attribute access. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Address second Copilot review round on #851 - Add parse_aggregate_report_file() to the library entry-point list in usage.md; the following paragraph describes the config= contract for "each of these functions", so the list must name all eight config-accepting entry points. - ParserConfig.__setstate__ now initializes every non-cache field to its class default before applying the pickled state, so a config serialized by an older parsedmarc version (whose state predates fields added later) unpickles with the newer fields at their defaults instead of unset entirely (__init__ never runs during unpickling, so an absent field would raise AttributeError on first access). Covered by a regression test that feeds __setstate__ a partial state dict. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com> |

Extend n_procs parallel parsing to mbox and mailbox sources (#147) (#849)
* Extend n_procs parallel parsing to mbox and mailbox sources (#147) n_procs previously applied only to report files passed directly as CLI arguments; messages from mbox files and mailbox connections (IMAP, Microsoft Graph, Gmail API, Maildir) were always parsed sequentially. A new parsedmarc.parallel module provides a shared bounded-window ProcessPoolExecutor helper (parallel_map) used by all three input paths. Only parsing fans out to a reused worker pool; message fetching, report deduplication, mailbox archiving/deletion, and output stay sequential in the main process. The submission window keeps at most ~2*n_procs messages in flight, so memory stays bounded even for huge mboxes, and the mailbox path fetches messages lazily on the connection-owning main thread. keep_alive never crosses the process boundary - the main process sends periodic IMAP keepalives while workers parse - and with n_procs > 1, invalid-message disposition happens after the parse phase, mirroring the existing deferred bulk archive moves. get_dmarc_reports_from_mbox, get_dmarc_reports_from_mailbox (including its tail-recursive re-check), and watch_inbox gain an n_procs keyword argument (default 1); sequential behavior at the default is unchanged. Replacing the CLI's hand-rolled Pipe/Process batching also fixes two defects in the direct-file path: a child process that died from a non-ParserError exception left the parent blocked forever on conn.recv(), and the hard batch barrier let one slow file idle every other worker slot. Workers are now a reused pool (no fresh interpreter per file), with worker logging reconstructed via a spawn-safe pool initializer instead of fork inheritance. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Address Copilot and code-quality review feedback on #849 - parallel_map now validates n_procs >= 1 itself with a clear error instead of surfacing ProcessPoolExecutor's max_workers error later. The check raises eagerly at the call (the generator body moved into an inner function) rather than on first iteration, with a regression test. - Aligned parallel_map's should_stop docstring with the implementation: queued-but-unstarted jobs are cancelled, while in-flight jobs are waited on and their results yielded, so the stop can block briefly but never discards completed work. - The parallel mailbox path keeps fetched message ids in a deque popped as each in-order result arrives, so the id queue stays bounded by the submission window instead of growing to message_limit. - Closed the three sample-file handles the new tests opened without a context manager. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Address second round of Copilot feedback on #849 - configure_logging no longer stacks duplicate FileHandlers when called again with the same log_file (compared by FileHandler.baseFilename, which stores the absolute path): a duplicate wrote every record twice and leaked a file descriptor per call, e.g. across SIGHUP config reloads. Latent in the pre-extraction cli._configure_logging too. Regression tests in the new tests/test_log.py. - Renamed the CHANGELOG's premature "10.4.0" heading to "Unreleased", matching the project convention where in-progress entries accumulate under Unreleased and the release PR renames the section and bumps parsedmarc/constants.py together (as in the 10.3.0 release).

Upgrade ruff to 0.16.0 and pyright to 1.1.411; convert to f-strings (#847)
* Upgrade ruff to 0.16.0 and pyright to 1.1.411; convert to f-strings ruff 0.16.0 expanded the default lint rule selection well beyond the long-standing E4/E7/E9/F, so [tool.ruff.lint] now selects the rule set explicitly: the pre-0.16 defaults plus the modern-type-hint UP rules and the two f-string rules (UP030/UP032). All 352 UP030/UP032 findings were auto-fixed; conversions requiring Python 3.12 f-string quote reuse were conservatively left as .format() by ruff (verified: the whole package and test suite byte-compile under CPython 3.10.20, the oldest CI version). Adopting the other newly-default rule families (BLE, SIM, C4, DTZ, I, ...) is deferred as a deliberate per-family decision. ruff format with 0.16.0 also now formats Python code fences in Markdown, which reformatted one block in parsedmarc/resources/maps/AGENTS.md. ruff check, ruff format --check, pyright (0 errors/warnings), and the full test suite (775 passed) are green on the new versions. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Address Copilot review findings on the f-string conversion - Rewrite messages that used backslash line continuations inside string literals, which embedded the source indentation as literal whitespace in the logged/raised text: the duplicate search-error messages in the Elasticsearch and OpenSearch outputs, the 'since'-option warning (which also implicitly concatenated "24hrs" and "SMTP" with no separator) and the IMAP 'since' debug line, and the missing-org_name KeyError message. - Build the Splunk HEC newline-delimited payloads by appending to a list and joining once instead of quadratic string concatenation in a loop. Declined: switching the webhook output's logger.error to logger.exception — the single-line ERROR without a traceback is the deliberate house pattern for batch-resilient sinks, and changing log verbosity is out of scope for this refactor PR. ruff check/format, pyright (0 errors/warnings), 775 tests, and a CPython 3.10 compileall all pass.

Normalize aggregate result words to lowercase (#835)
* fix: normalize aggregate result words Normalize policy-evaluated and authentication result values so mixed-case reporter output does not create duplicate categories. Add a regression covering the existing uppercase sample. * Move changelog entry to the Unreleased section The entry landed in the released 10.2.4 section because the branch was cut before the Unreleased heading existed on master; merged master and moved it under Unreleased -> Bug fixes, matching the house entry style. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Apply review feedback: normalize disposition, share a guarded helper - policy_evaluated disposition gets the same lowercase normalization as dkim/spf and the auth result words; the RFC 7489 Appendix C / RFC 9990 disposition enum is lowercase (none/quarantine/reject), and mixed-case values split the Message Disposition categories in every dashboard the same way Pass/pass did. - All four normalization sites now share _normalize_result_word(), which guards with isinstance(str): xmltodict returns a dict for attribute-bearing elements, so the previously unguarded .lower() calls on auth results could raise AttributeError on malformed input that used to pass through. - The #520 fixture's disposition is now mixed-case (None) and the test asserts it parses as "none"; verified the assertion fails against the pre-fix parser. Test docstring cites the RFC authority per the project's testing standards.

Some Exim/cPanel-based gateways send DMARC failure reports without a machine-readable message/feedback-report part. parse_report_email()'s plain-text fallback synthesizes a minimal feedback report with only Arrival-Date and Source-IP, but the Elasticsearch/OpenSearch outputs access feedback_type and authentication_results with hard key lookups, so every such report was archived but never indexed, failing with "Failure report missing required field: 'feedback_type'". parse_failure_report() now defaults feedback_type to auth-failure (RFC 5965 3.1) and authentication_results to None (RFC 6591 3.1) with logged warnings, matching the existing handling of the REQUIRED Auth-Failure and Identity-Alignment fields. Adds a sanitized sample and a regression test asserting the sink-required keys are present. |

Refresh Microsoft Graph docs: national clouds, examples, troubleshooting (#826)
* Send report summary via Microsoft Graph; make Graph failures observable
Two related fixes shipped together:
Send via Graph: the periodic DMARC summary email can now be sent
through the already-authenticated Microsoft Graph mailbox connection
(MSGraphConnection.send_message(), /users/{mailbox}/sendMail) instead
of only SMTP. Triggered when [msgraph] is configured and [smtp] has a
`to` value but no `host` -- SMTP is always preferred when `host` is
set, with no automatic fallback to Graph on SMTP failure. Reuses the
same connection used for reading; no new send-only config mode.
email_results()'s SMTP behavior is unchanged; a new
email_results_via_msgraph() shares its content-building logic via a
new _build_report_email_content() helper. Graph's sendMail always
sends as the authenticated mailbox, so [smtp] from is ignored on this
path -- documented, along with the required Mail.Send permissions and
a caveat that delegated auth flows (UsernamePassword/DeviceCode) don't
currently request that scope, so app-only auth is the supported path
for sending. Tracks #472.
Observable Graph failures: MSGraphConnection construction, mailbox
fetch, message send, and --watch failures now catch
ClientAuthenticationError/APIError/httpx.HTTPError specifically and
log one clear ERROR line naming the mailbox, tenant, auth method, and
the Graph request-id/client-request-id when available, instead of a
bare "MS Graph Error"/"Mailbox Error" with no context. Full traceback
still preserved at --debug. --watch previously had no Graph-specific
error handling at all -- a Graph error there crashed with a raw
uncaught traceback; it now exits the same way as the other three
sites. No new config options.

* Refresh Microsoft Graph docs: national clouds, examples, troubleshooting
The [msgraph] docs were accurate but missed guidance the community has
been asking for:
- graph_url now lists the actual national/sovereign-cloud endpoint
values (GCC High, DoD, China/21Vianet), with an explicit warning
that setting it alone is not sufficient -- the Entra ID auth
endpoint isn't independently configurable in parsedmarc or
mailsuite, so it always hits the global login.microsoftonline.com.
- A minimal working [msgraph] example for every auth method
(UsernamePassword, DeviceCode, ClientSecret, Certificate,
ClientAssertion) -- previously only Certificate had one, entangled
with the SMTP-sending example.
- A reading-permission matrix alongside the existing sending one, so
every auth method x own/shared-mailbox combination is explicit in
one place for both directions.
- An accurate note on the parsedmarc-named token cache: it's a
deliberate backward-compatibility choice from the 9.11.0 mailsuite
extraction (mailsuite's own default cache name differs), not a
migration users need to act on.
- A troubleshooting table for four error scenarios, verified against
source rather than assumed: admin consent and folder-resolution
failures are still live and documented with real fixes; the
event-loop and ISO-timestamp errors are historical, already fixed
below this project's dependency/version floor.

Raise test coverage: utils.py, elastic.py, and opensearch.py to 100% (#816)
* Raise test coverage: utils, elastic, and opensearch to 100%
Coverage of the shipped library rises from 88% to 90%, with
parsedmarc/utils.py 86% -> 100% and elastic.py / opensearch.py
99% -> 100%. All new tests assert on observable behaviour and mock
only at SDK boundaries (dnspython Resolver.resolve, requests.get,
subprocess.check_call, elasticsearch_dsl/opensearchpy Document.save).
New tests cover: query_dns transient-error retries, the load_ip_db
download/cache/bundled fallback chain, the IPinfo API token probe and
per-request MMDB fallbacks, _normalize_ip_record schema handling,
reverse-DNS-map invalid-CSV fallback, caller-provided reverse DNS
maps, Outlook MSG conversion (missing msgconvert and success paths),
parse_email Cc/Bcc/attachment-hash branches, aggregate-XML edge cases
(bytes input, repeated policy_published, unknown RFC 9990 override
types, missing org_name, attribute-only <email>), extract_report on
non-seekable streams, and the _AggregateReportDoc.save() override
that derives passed_dmarc.
Bugs found by the new tests, fixed in the same PR per the testing
standards:
- parse_email() crashed with KeyError: 'Headers' on messages whose
From header is present but unparseable (e.g. a bare "From:" line):
the fallback read parsed_email["Headers"], but the parsed headers
are stored under lowercase "headers" (assigned a few lines up in
the same function), so the key never exists. At the CLI surface
this made any failure report whose embedded sample had an empty
From: header fail to parse ("Missing value: 'Headers'").
- configure_ipinfo_api(probe=True) logged "IPinfo API configured"
when the probe could not reach the API, contradicting its own
docstring ("other errors are logged and the token is still
accepted"): _ipinfo_api_lookup() returns None on network errors
instead of raising, so the probe's exception handler was
unreachable. The probe now checks the lookup result and warns on
failure; 401/403 still raises InvalidIPinfoAPIKey.
Dead code deleted rather than padded with tests:
- _SMTPTLSReportDoc.add_policy() in elastic.py and opensearch.py
(the save paths construct _SMTPTLSPolicyDoc directly).
- The no-op "for failure_index in failure_indexes: pass" loop in
both migrate_indexes() implementations (parameter still accepted).
- The importlib.resources ImportError fallback in utils.py, which
re-imported the same module and is unreachable on Python >= 3.10.
- The "Invalid report content" guard in extract_report(): every
input branch assigns file_object or raises first (confirmed by
pyright narrowing with the guard removed).
Also widens parse_aggregate_report_xml's annotation to str | bytes
to match its existing runtime behaviour (bytes are decoded with
errors ignored).

* Use assertGreater for the reverse-DNS-map fallback size check
Addresses the github-code-quality bot finding on PR #816: assertTrue
with a comparison inside can't show the operands on failure, while
assertGreater reports both values and the failed relation. No change
to test behavior.

10.2.0 - Explain why a report is invalid instead of "Not a valid report" (#802)
* Explain why a report is invalid instead of "Not a valid report"
The parser catches broadly so one malformed report can't crash a batch,
but every failure surfaced as the generic ParserError("Not a valid
report"), telling operators nothing about the cause.
parse_report_file() now keeps each format parser's specific error as it
tries aggregate XML -> SMTP TLS JSON -> report email, and when all three
reject the input it content-sniffs the leading byte to surface the single
relevant reason (e.g. "Invalid aggregate report: Missing field:
'org_name'", or "Not a recognized report format (...)"). The CLI already
logs str(error), so this reaches the user with no cli.py change.
Every parser catch site also re-raises with `raise ... from <original>`,
preserving the underlying ExpatError / JSONDecodeError / KeyError /
archive errors on __cause__ for library callers and tracebacks. The same
exception *types* are still raised.
Finally, the catch-all "unexpected error" branches append
`(raised at <file>:<line>)` from the deepest traceback frame, but only
when the parsedmarc logger is at DEBUG level (e.g. the CLI's --debug);
normal-level output is unchanged.
Bumps the in-progress version to 10.2.0 and documents all three in the
CHANGELOG.

* Cover the failure-report path in parse_report_file error tests
The reason-surfacing tests covered the aggregate and SMTP TLS branches but
not failure reports, which reach parse_report_file only via the email
path. Add a malformed multipart/report failure email (missing the required
Source-IP) and assert the message names the failure format and the missing
field rather than collapsing to "Not a valid report".
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* Cover the new error-reporting lines; drop one unreachable catch
Bring the lines added by this PR to full test coverage:
- Test _exc_origin() with a never-raised exception (no __traceback__) so the
"no frames" guard is exercised.
- Test _parse_smtp_tls_failure_details() with a non-dict, which raises
TypeError (not KeyError) and exercises the generic catch-all.
- Test parse_report_email() with an unparseable Date header, which trips the
initial mail-parse catch-all and becomes a ParserError.
Two dead lines are removed rather than hidden, per the project's "delete
unreachable branches, no # pragma: no cover" rule:
- _looks_like_email() looped with a `continue` for blank lines, but every
caller passes lstrip()-ed text, so the first line is never blank. Simplified
to inspect the first line directly.
- parse_report_email()'s `except Exception` after `except InvalidFailureReport`
was unreachable: parse_failure_report wraps its entire body and provably
raises only InvalidFailureReport, which the preceding handler already catches.

* Fix IndexError when backfilling envelope_from from SPF results
_parse_report_record() backfills a missing/empty envelope_from from the
last SPF auth result's domain. The "envelope_from is None" branch gated on
the raw auth_results["spf"] list but indexed the filtered
new_record["auth_results"]["spf"] list, which only holds results that have
a domain. A reporter sending an SPF result with no domain made the filtered
list empty while the raw list was non-empty, so [-1] raised IndexError and
the whole record failed to parse.
The two near-identical envelope_from backfill branches (missing identifier
vs. empty identifier) drifted apart -- only one was updated when the
filtered new_record list was introduced -- which is what let them disagree
on which list to read. Merge them into a single path, keyed on
dict.get("envelope_from") is None, that gates and indexes the same raw list
with the "domain" membership guard the missing-identifier branch already
used.
Regression test: envelope_from=None with an SPF result carrying no domain
now parses to envelope_from=None instead of raising. This is the bug that
motivated the surrounding error-reporting work in this PR.

* Trim comment
* Cover the touched error branches; drop a dead UnicodeDecodeError catch
Codecov flagged the pre-existing error branches this PR touched (adding
`from e` / `_exc_origin`) as changed-and-uncovered. Most are real
malformed-report paths, so add honest tests that drive them with realistic
inputs:
- parse_smtp_tls_report_json: nested missing key (date-range without
start-datetime) -> InvalidSMTPTLSReport chaining a KeyError.
- parse_aggregate_report_xml: non-structured report_metadata -> the
AttributeError branch ("Report missing required section").
- parse_report_email: valid legacy text/plain failure report (success path),
a text report missing its fields, a base64 attachment of malformed
aggregate XML, and one of invalid SMTP TLS JSON.
- parse_report_file: gzipped junk -> the str branch of the content sniff.
The `except UnicodeDecodeError` in extract_report is removed as dead code
(no `# pragma: no cover`, per the repo rule): str-mode streams are already
rejected by explicit isinstance checks, and every decode() uses
errors="ignore", so it can never fire. str-mode still raises ParserError.
Also rename the two new failure-report tests from "Forensic" to "Failure"
and add an AGENTS.md rule: RUF reports are "failure reports"; "forensic" is
reserved for the literal backward-compat alias identifiers only.

* Fix pyright errors in the new error-branch tests
CI runs pyright over the whole repo (tests included); these slipped through
because the local check only covered parsedmarc/__init__.py:
- _parse_smtp_tls_failure_details("not a dict") is a deliberate wrong-type
test -> targeted `# pyright: ignore[reportArgumentType]`.
- result["report"]["source"]["ip_address"] on a ParsedReport TypedDict ->
cast(FailureReport, result["report"]) first, matching existing tests.
This is what failed lint-docs-build (and, since `test` needs it, skipped the
Codecov upload) on the prior commits.

Make the whole codebase pass pyright cleanly and enforce it in CI (#798)
* Make the whole codebase pass pyright cleanly and enforce it in CI Fix all 102 pyright (1.1.410, standard mode) errors across the library, tests, and maps scripts, then pin and enforce the zero-errors bar: - postgres.py: make the optional psycopg import TYPE_CHECKING-aware so the module is properly typed while keeping the runtime install-hint fallback; import psycopg.types.json explicitly as psycopg_json (the old psycopg_types.json attribute access only worked because psycopg imports the submodule eagerly); have _connect()/_ensure_connected() return the live connection so save methods use a non-Optional local; type the DDL list as list[LiteralString] to match psycopg's execute() overloads. - kafkaclient.py: resolve the kafka-python 2.x/3.x bootstrap-error fallback statically via TYPE_CHECKING (kafka-python 3.0 removed NoBrokersAvailable), which also fixes _BootstrapError's import resolution in tests. - syslog.py: go through getattr/setattr for SysLogHandler.socket (absent from typeshed); type the save_* methods with the report TypedDicts (single or list, matching cli.py call sites — gelf.py gets the same signatures); raise ValueError when retry_attempts < 1 instead of falling through and registering a None handler (bug fix, with a regression test and a CHANGELOG entry). - elastic.py / opensearch.py: human_result params are Optional[str]. - maps scripts: sort_csv declared a return type but never returned (now -> None); seen_sort_field_values was possibly unbound; convert_to_utf8's src_encoding is Optional[str]. - tests: cast sample-report dict helpers to their TypedDicts; mark deliberate wrong-type calls with targeted pyright ignores; add narrowing asserts for Optional results; access the mocked KafkaProducer through a cast helper; match the mailsuite fetch_message base signature (**kwargs); patch the renamed parsedmarc.postgres.psycopg_json in test_postgres's setUpModule. Enforcement: [tool.pyright] in pyproject.toml (include parsedmarc, tests, docs; standard mode), pyright==1.1.410 pinned in the [build] extra (pinned exactly so a new pyright release can't break CI without a code change), and a "Check types" step in the lint CI job — which now also runs ruff format --check and installs the [postgresql] extra so the optional psycopg import resolves. Documented in AGENTS.md. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Set session headers via update() instead of replacing the dict requests 2.34 ships inline type annotations, and Session.headers is a CaseInsensitiveDict[str] — assigning a plain dict fails pyright there (the CI runner resolved 2.34.2; the local venv's untyped 2.32.4 hid it). headers.update() is correctly typed against both versions, and is the documented requests idiom: it overrides User-Agent and the client-specific headers while keeping the session's defaults (Accept-Encoding, Connection) instead of wiping them.

test: cover parsedmarc's mailbox processing loop end-to-end on a real Maildir (#777)
AGENTS.md notes get_dmarc_reports_from_mailbox was halted at low coverage
because honest testing needed a live IMAP server or mocks so deep they test
the mock. mailsuite's MaildirConnection is a real on-disk backend with no
network or credentials, so the fetch -> parse/classify -> route loop can now be
exercised for real in CI.
TestGetDmarcReportsFromMailboxMaildir delivers real sample reports (one
aggregate, failure, and SMTP-TLS email) plus an unparseable message into a
Maildir INBOX, runs get_dmarc_reports_from_mailbox offline, and asserts on
observable results — parsed report counts and which archive subfolder each
message physically lands in:
- each report type routed to Archive/{Aggregate,Failure,SMTP-TLS}, the junk
message to Archive/Invalid, INBOX drained
- delete=True removes processed messages instead of archiving them
- test=True parses and returns reports but moves nothing and creates no folders
setUp resets the module-global SEEN_AGGREGATE_REPORT_IDS dedup cache so test
order can't drop an already-"seen" aggregate report, and the maildir lives at a
fresh subpath so mailbox.Maildir(create=True) actually builds cur/new/tmp.
Lifts parsedmarc/__init__.py from 76% to 82%, honestly.

Finish forensic→failure rename: archive-folder migration + dashboard/doc cleanup (#776)
The forensic→failure rename (#659) left a few loose ends and one deliberate hold-back. This closes them. Leftover rename misses (broken paths / stale canonical names): - CONTRIBUTING.md, dashboard-dev-bootstrap.sh: samples/forensic/* → samples/failure/* - dashboard-dev-bootstrap.sh, dashboards/README.md: dmarc_forensic_dashboard.xml → dmarc_failure_dashboard.xml (the file was already renamed; the import path and view name were not) - docs/source/usage.md: PARSEDMARC_GENERAL_SAVE_FORENSIC → ..._SAVE_FAILURE example - samples/parsedmarc.ini: save_forensic → save_failure - pyproject.toml, README.md: canonical "failure" naming (ci.ini intentionally keeps save_forensic to smoke-test the deprecated alias.) Archive subfolder rename + on-startup migration: - New failure reports now archive to <archive>/Failure (was <archive>/Forensic). - _migrate_forensic_archive_folder() runs once on startup (best-effort): renames Forensic→Failure when no Failure folder exists yet, merges the two when both exist, no-ops when there's no legacy folder, and logs-and-skips a mailbox it can't reorganize (warn, don't crash). This consolidates pre- and post-rename failure reports into one folder, replacing the previously documented decision to keep the folder named Forensic to avoid a split archive. Uses the folder-management API (folder_exists / rename_folder / merge_folders) added in mailsuite 2.1.0; the pin is bumped to >=2.1.0. Grafana dashboard (the rename PR updated OSD/Splunk/ES-OS but not Grafana): - Forensic panel titles + the datasource label → Failure; the fo-column display label and its linked byName field-override matcher both → "Failure Policy" (changed together so the column-width override keeps matching). - dev-bootstrap Grafana ES datasource: dmarc_forensic* → dmarc_f* (matches both pre-rename dmarc_forensic* and post-rename dmarc_failure*, like the OSD/Kibana dashboards); RESEED wipe loop now also clears dmarc_failure* indices. - Removed dashboards/grafana/Grafana-DMARC_Reports.json-new_panel.json, an orphan export accidentally committed in #736 and referenced by nothing. Tests (tests/test_init.py): - TestMigrateForensicArchiveFolderMaildir: real on-disk Maildir round-trips via mailsuite's MaildirConnection (no mocks) — rename, merge, no-op, and the full get_dmarc_reports_from_mailbox orchestration. Runs in CI (no network/creds). - TestMigrateForensicArchiveFolderErrorHandling: the one path a real Maildir can't reproduce — a backend that raises mid-operation must warn, not crash.

Expand honest test coverage from 59% to 83%; fix two latent bugs (#775)
* Expand honest test coverage from 59% to 83%; fix two latent bugs 271 new tests across the output modules, ES/OS clients, CLI config parsing, and the top-level parsing surface. Coverage measured against shipped code only (see [tool.coverage.run] source = ["parsedmarc"] omit = ["*/parsedmarc/resources/maps/*.py"] in pyproject.toml). Per-module results: s3.py 38% → 100% (also fixes SMTP-TLS-to-S3 bug below) gelf.py 40% → 100% syslog.py 46% → 100% kafkaclient.py 34% → 100% splunk.py 24% → 100% loganalytics.py 56% → 100% webhook.py 78% → 100% (also removes redundant try/except) elastic.py 36% → 99% opensearch.py 40% → 99% cli.py 52% → 69% __init__.py 74% → 76% (also fixes append_json bug below) utils.py 84% (unchanged in this PR) TOTAL 59% → 83% The remaining 17% is honest. The biggest unreached blocks are _main() in cli.py and the watch-mode mailbox iteration in __init__.py, both of which would require either standing up live subsystems (real Elasticsearch, real IMAP) or mocking deep enough that the test would verify the mock rather than the code. The PR-A AGENTS.md guidance — "if 90% requires faking it, ship 85% honestly" — applies here. Bugs fixed while writing tests: 1. parsedmarc/s3.py — SMTP-TLS-to-S3 was completely broken. save_report_to_s3 unconditionally read report["report_metadata"] when building S3 object metadata, but RFC 8460 §4.3 SMTP TLS reports are flat (no report_metadata sub-object). The CLI's surrounding try/except silently swallowed the KeyError, so every SMTP-TLS report quietly failed to upload. Also fixes a related issue: parse_smtp_tls_report_json stores begin_date as the raw ISO-8601 string from the report (per the SMTPTLSReport TypedDict and RFC 8460 §4.3), but the S3 code path assumed a datetime with .year / .month / .day attributes. Both fixed; the broken metadata-extraction branch now uses the flat-report fields, and the date branch normalizes via human_timestamp_to_datetime. 2. parsedmarc/__init__.py — append_json corrupted JSON output files on the second write. The original implementation opened files in "a+" mode, then seek()ed backwards to overwrite the trailing "]" with ",\n" before appending more elements. Python's docs are explicit (https://docs.python.org/3/library/functions.html#open): on POSIX, writes in "a"/"a+" mode always go to EOF regardless of seek() position. The result was that the second call produced [...]\n],\n[...] -style corrupted output instead of a single merged array. Replaced with a read-merge-write pattern: load the existing array (if any), append the new elements, rewrite the whole file. The CSV cousin append_csv was not affected — it doesn't seek backwards. 3. parsedmarc/webhook.py — removed redundant try/except blocks in save_aggregate_report_to_webhook / save_failure_report_to_webhook / save_smtp_tls_report_to_webhook. _send_to_webhook already catches every Exception itself, so the outer except blocks were unreachable dead code (covered nothing, defended against nothing, and inflated the source-line count without testing value). Testing approach: mocks at SDK boundaries (boto3 resource, kafka producer, requests session, opensearch/elasticsearch Document/Search, azure LogsIngestionClient). Tests verify the parsedmarc-side transformation logic — document/event construction, index/topic naming, dedup queries, error wrapping — rather than asserting on mock invocations as a proxy for behaviour. Where a branch is defensive against a caller that doesn't exist in the codebase, the test is omitted (commented in code rather than hidden behind a pragma). 547 tests total (was 276), all passing. ruff check + format clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Document the two bug fixes from this PR in the 10.0.0 changelog Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Document testing standards in AGENTS.md Adds a "Testing standards" section covering the principles applied in PR-A (split) and PR-B (coverage expansion): - Coverage measures shipped code only — don't reintroduce tests/* to the scope, don't expand omit, don't use # pragma: no cover. - Honest tests assert on observable behaviour, not "the mock was called". Mock at SDK boundaries; parse the payload that gets sent. - "If 90% requires faking it, ship 85% honestly" — coverage is a tool, not a goal. PR-B's deliberate stops at cli.py 69% and __init__.py 76% are the documented precedent for when to halt. - Verify bug claims against the relevant RFC, internal types, installed SDK source, or upstream docs before changing code. Cite the source in the commit message and test docstring (RFC 8460 §4.3 and the Python open() docs for #775's two bug fixes are the pattern to follow). - Bugs found while writing tests are fixed in the same PR; the test doubles as the regression guard. - File layout (tests/test_<module>.py) is non-negotiable; module-level test loggers need fresh-handler setup so test ordering doesn't break assertLogs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Cover the corrupt-file fallback in append_json Codecov flagged 2 missing patch-coverage lines on PR #775: the except (json.JSONDecodeError, OSError) branch in append_json, which falls back to overwriting when the existing file isn't a parseable JSON array. Two new tests in tests/test_init.py:TestAppendJson exercise both paths: - test_corrupt_existing_file_is_overwritten_cleanly: existing file contains invalid JSON; append_json overwrites with the new array. - test_existing_file_with_non_list_root_is_overwritten: existing file parses as {"foo": ...} (dict, not list); the isinstance guard rejects it and we overwrite cleanly.

Split tests.py into per-module tests/test_<module>.py (#774)
* Split tests.py into per-module tests/test_<module>.py The 5174-line tests.py monolith is split into per-module files under tests/, mirroring the checkdmarc layout: tests/test_init.py parsedmarc/__init__.py parsing surface tests/test_cli.py parsedmarc/cli.py + config / env-vars / SIGHUP tests/test_utils.py parsedmarc/utils.py (DNS, IP info, PSL, etc.) tests/test_webhook.py parsedmarc/webhook.py tests/test_kafkaclient.py parsedmarc/kafkaclient.py tests/test_splunk.py parsedmarc/splunk.py tests/test_syslog.py parsedmarc/syslog.py tests/test_loganalytics.py parsedmarc/loganalytics.py tests/test_gelf.py parsedmarc/gelf.py tests/test_s3.py parsedmarc/s3.py tests/test_maps.py parsedmarc/resources/maps/ maintainer scripts The split is purely a redistribution — no test bodies changed, no tests added or removed. All 276 existing tests pass under the new layout. The current tests.py contains two kitchen-sink classes (`Test` at line 54 and `TestEnvVarConfig` at line 2360) holding tests that span many modules. Their methods are routed to the correct per-module file by name prefix; the wholly-thematic classes (TestExtractReport, TestUtilsXxx, TestSighupReload, etc.) move whole. Each target file gets its own `class Test(unittest.TestCase)` for the redistributed kitchen-sink methods, plus the thematic classes verbatim. Wiring updates: - `.github/workflows/python-tests.yml`: `pytest ... tests.py` → `python -m pytest ... tests/` (also switches to `python -m pytest` per the checkdmarc convention so cwd lands on the project root). - `pyproject.toml`: adds `[tool.pytest.ini_options] testpaths = ["tests"]` and `[tool.coverage.run] source = ["parsedmarc"]` with an `omit` for `parsedmarc/resources/maps/*.py`. The maps scripts are maintainer-only batch tooling that ships out of the wheel; excluding them from coverage makes the headline number reflect only installed library code. Runtime coverage on the new layout is 59% (was 45% with maps counted), and PR-B will push it to 90%+. - `AGENTS.md`: documents the new layout and how to run individual files / tests; tells future contributors not to reintroduce a monolithic tests.py. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Restore 66.9% coverage baseline (count tests/ + parsedmarc) Master's headline 66.9% number on Codecov includes the tests.py file itself (99.35% covered) being measured alongside parsedmarc/*. The original tests.py had no `[tool.coverage.run]` block, so coverage's default — "measure every file imported during the run" — counted the test code as if it were product code. The split commit added `source = ["parsedmarc"]` which suppressed measurement of the test files (correct in principle, since test files aren't shipped code), and that alone made the headline number drop by ~8 percentage points without any actual loss of testing. This commit swaps `source` for an explicit `include = ["parsedmarc/*", "tests/*"]` so both halves are measured the way they were on master. Verified: 276 tests, 66.96% line coverage (effectively unchanged from master's 66.90%). If you want the shipped-code-only number (was the headline that this commit overrides), run `pytest --cov=parsedmarc tests/`. That number is currently 59% and is the focus of the upcoming coverage-expansion PR. Also adds junit.xml to .gitignore so the CI artefact doesn't get accidentally committed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * Restrict coverage to shipped code (`source = ["parsedmarc"]`) Reverts the prior commit's `include = ["tests/*"]`. Counting the test files toward coverage was wrong — it conflates "shipped code exercised by tests" with "test code that pytest auto-runs", inflates the headline number, and rewards writing more tests rather than tests that verify more code. Master's apparent 66.9% was an artefact of the old monolithic tests.py having no [tool.coverage.run] block at all; coverage's default behaviour measured every imported file, including the test file itself at ~99% "covered", which added ~8 percentage points to the displayed number without any real testing signal. Restricting to `source = ["parsedmarc"]` plus the existing maps omit gives a meaningful baseline: 59% of shipped code is exercised by the test suite today. That's the number the next PR is targeting to lift to 90%+ before the 10.0.0 release; the Codecov "drop" here is a measurement correction, not a regression.
