Rough steps:
```
mv cmd/restic/global* cmd/restic/secondary_repo* internal/global/
sed -i "s/package main/package global/" internal/global/*.go
Rename "GlobalOptions" to "Options" in internal/global/
Replace everywhere " GlobalOptions" -> " global.Options"
Replace everywhere "\*GlobalOptions" -> " *global.Options"
Make SecondaryRepoOptions public
Make create public
Make version public
```
The new functions much better convey the intent behind the lock
request. This allows cleanly integrating noLock (for read) and dryRun
(write/exclusive) handling.
There are only minor changes to existing behavior with two exceptions:
- `tag` no longer accepts the `--no-lock` flag. As it replaces files in
the repository, this always requires an exclusive lock.
- `debug examine` now returns an error if both `--extract-pack` and
`--no-lock` are given.
It was only used in two places:
- stats: apparently as a minor performance optimization, which is
unlikely to be important
- find: filtered directories would be ignored. However, this
optimization missed that it is possible that two directories have the
exact same content. Such directories would be incorrectly ignored too.
Example:
```
mkdir test test/a test/b
restic backup test
restic find latest test/b
-> incorrectly does not return anything
```
Thus, remove the functionality as it's apparently too complex to use
correctly.
inodes are only unique within a device. Use the HardlinkIndex from the
restorer instead of the custom (broken) hashmap to correctly account for
both inode and deviceID.
Fixes restic#719
If the option is passed, restic will wait the specified duration of time
and retry locking the repo every 10 seconds (or more often if the total
timeout is relatively small).
- Play nice with json output
- Reduce wait time in lock tests
- Rework timeout last attempt
- Reduce test wait time to 0.1s
- Use exponential back off for the retry lock
- Don't pass gopts to lockRepo functions
- Use global variable for retry sleep setup
- Exit retry lock on cancel
- Better wording for flag help
- Reorder debug statement
- Refactor tests
- Lower max sleep time to 1m
- Test that we cancel/timeout in time
- Use non blocking sleep function
- Refactor into minDuration func
