Note: this is the default cache implementation in borg 1.x,
it worked well, but there were some issues:
- if the local chunks cache got out of sync with the repository,
it needed an expensive rebuild from the infos in all archives.
- to optimize that, a local chunks.archive.d cache was used to
speed that up, but at the price of quite significant space needs.
AdhocCacheWithFiles replaced this with a non-persistent chunks cache,
requesting all chunkids from the repository to initialize a simplified
non-persistent chunks index, that does not do real refcounting and also
initially does not have size information for pre-existing chunks.
We want to move away from precise refcounting, LocalCache needs to die.
Also: support a "cli" env var value, that does not determine
the implementation from the env var, but rather from cli options (similar to as it was before adding BORG_CACHE_IMPL).
- macOS: run on macos-14 (on Apple Silicon!)
- macOS: use OpenSSL 3.0 from brew
- macOS: run with Python 3.11
- pip install -e .: add -v
- use up-to-date github actions
- remove libb2 references - since borg 1.2, we use blake2 indirectly via python stdlib
borg init calls this. If there is a PermissionError, it is
usually fs permission issue at path or its parent directory.
Don't give a traceback, but rather an error msg and a specific exit code.
- implement updating exit code based on severity, including modern codes
- extend print_warning with kwargs wc (warning code) and wt (warning type)
- update a global warnings_list with warning_info elements
- create a class hierarchy below BorgWarning class similar to Error class
- diff: change harmless warnings about speed to rc == 0
- delete --force --force: change harmless warnings to rc == 0
Also:
- have BackupRaceConditionError as a more precise subclass of BackupError
