07bca1ad28 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.

* 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.

* 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).

* 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.

* 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.

* 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.

Sean WhalenandClaude Fable 5 eaeea4f53d 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.

* 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.

Sean WhalenandClaude Fable 5 0c456d44ed Declare backward-compatible method aliases inside class bodies (#797)
* Declare backward-compatible method aliases inside class bodies

Assigning the legacy save_forensic_* aliases onto the classes after the
class body (KafkaClient.save_forensic_reports_to_kafka = ...) is invisible
to static type checkers, so Pylance/Pyright flagged every assignment and
every use with reportAttributeAccessIssue. Declaring the alias inside the
class body is statically visible — the IDE errors disappear and the
aliases get autocomplete and proper typing. Runtime behavior is identical
(same function object bound as a method), guarded by the existing
assertIs alias tests, whose type-ignore comments are now unnecessary.

Also add a pyright ignore on the NoBrokersAvailable import in
kafkaclient.py: the import is guarded by try/except ImportError for
kafka-python 2.x, but Pyright resolves against the installed 3.x where
the name no longer exists.

Sean WhalenandClaude Opus 4.7 b7b8383fa4 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.

* 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.

* 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.

Patch coverage now 100% on the bug fix.

Sean WhalenandClaude Opus 4.7 5b08627eaa 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.

* 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.
