Log Message:
py-borgbackup: update to 1.2.0.

Version 1.2.0 (2022-02-22 22:02:22 :-)
--------------------------------------

Please note:

This is the first borg 1.2 release, so be careful and read the notes below.

Upgrade notes:

Strictly taken, nothing special is required for upgrading to 1.2, but some
things can be recommended:

- do you already want to upgrade? 1.1.x also will get fixes for a while.
- be careful, first upgrade your less critical / smaller repos.
- first upgrade to a recent 1.1.x release - especially if you run some older
  1.1.* or even 1.0.* borg release.
- using that, run at least one `borg create` (your normal backup), `prune`
  and especially a `check` to see everything is in a good state.
- check the output of `borg check` - if there is anything special, consider
  a `borg check --repair` followed by another `borg check`.
- if everything is fine so far (borg check reports no issues), you can consider
  upgrading to 1.2.0. if not, please first fix any already existing issue.
- if you want to play safer, first **create a backup of your borg repository**.
- upgrade to latest borg 1.2.x release (you could use the fat binary from
  github releases page)
- run `borg compact --cleanup-commits` to clean up a ton of 17 bytes long files
  in your repo caused by a borg 1.1 bug
- run `borg check` again (now with borg 1.2.x) and check if there is anything
  special.
- run `borg info` (with borg 1.2.x) to build the local pre12-meta cache (can
  take significant time, but after that it will be fast) - for more details
  see below.
- check the compatibility notes (see below) and adapt your scripts, if needed.
- if you run into any issues, please check the github issue tracker before
  posting new issues there or elsewhere.

If you follow this procedure, you can help avoiding that we get a lot of
"borg 1.2" issue reports that are not really 1.2 issues, but existed before
and maybe just were not noticed.

Compatibility notes:

- dropped support / testing for older Pythons, minimum requirement is 3.8.
  In case your OS does not provide Python >= 3.8, consider using our binary,
  which does not need an external Python interpreter. Or continue using
  borg 1.1.x, which is still supported.
- freeing repository space only happens when "borg compact" is invoked.
- mount: the default for --numeric-ids is False now (same as borg extract)
- borg create --noatime is deprecated. Not storing atime is the default behaviour
  now (use --atime if you want to store the atime).
- list: corrected mix-up of "isomtime" and "mtime" formats.
  Previously, "isomtime" was the default but produced a verbose human \ 
format,
  while "mtime" produced a ISO-8601-like format.
  The behaviours have been swapped (so "mtime" is human, \ 
"isomtime" is ISO-like),
  and the default is now "mtime".
  "isomtime" is now a real ISO-8601 format ("T" between date \ 
and time, not a space).
- create/recreate --list: file status for all files used to get announced *AFTER*
  the file (with borg < 1.2). Now, file status is announced *BEFORE* the file
  contents are processed. If the file status changes later (e.g. due to an error
  or a content change), the updated/final file status will be printed again.
- removed deprecated-since-long stuff (deprecated since):

  - command "borg change-passphrase" (2017-02), use "borg key \ 
..."
  - option "--keep-tag-files" (2017-01), use \ 
"--keep-exclude-tags"
  - option "--list-format" (2017-10), use "--format"
  - option "--ignore-inode" (2017-09), use "--files-cache" \ 
w/o "inode"
  - option "--no-files-cache" (2017-09), use \ 
"--files-cache=disabled"
- removed BORG_HOSTNAME_IS_UNIQUE env var.
  to use borg you must implement one of these 2 scenarios:

  - 1) the combination of FQDN and result of uuid.getnode() must be unique
       and stable (this should be the case for almost everybody, except when
       having duplicate FQDN *and* MAC address or all-zero MAC address)
  - 2) if you are aware that 1) is not the case for you, you must set
       BORG_HOST_ID env var to something unique.
- exit with 128 + signal number, #5161.
  if you have scripts expecting rc == 2 for a signal exit, you need to update
  them to check for >= 128.

Fixes:

- diff: reduce memory consumption, fix is_hardlink_master, #6295
- compact: fix / improve freeable / freed space log output

  - derive really freed space from quota use before/after, #5679
  - do not say "freeable", but "maybe freeable" (based on \ 
hint, unsure)
- fix race conditions in internal SaveFile function, #6306 #6028
- implement internal safe_unlink (was: truncate_and_unlink) function more safely:
  usually it does not truncate any more, only under "disk full" \ 
circumstances
  and only if there is only one hardlink.
  see: https://github.com/borgbackup/borg/discussions/6286

Other changes:

- info: use a pre12-meta cache to accelerate stats for borg < 1.2 archives.
  the first time borg info is invoked on a borg 1.1 repo, it can take a
  rather long time computing and caching some stats values for 1.1 archives,
  which borg 1.2 archives have in their archive metadata structure.
  be patient, esp. if you have lots of old archives.
  following invocations are much faster due to the cache.
  related change: add archive name to calc_stats progress display.

  - add borg 1.2 upgrade notes, #6217

- new BORG_WORKAROUNDS mechanism, basesyncfile, #4710
- remove WSL autodetection. if WSL still has this problem, you need to
  set BORG_WORKAROUNDS=basesyncfile in the borg process environment to
  work around it.
- support xxh64 checksum in addition to the hashlib hashes in borg list
- enable placeholder usage in all extra archive arguments
- enable placeholder usage in --comment, #4559
- enable placeholder usage in --glob-archives, #4495
- ability to use a system-provided version of "xxhash"
- create:

  - changed the default behaviour to not store the atime of fs items. atime is
    often rather not interesting and fragile - it easily changes even if nothing
    else has changed and, if stored into the archive, spoils deduplication of
    the archive metadata stream.
  - if you give the --noatime option, borg will output a deprecation warning
    because it is currently ignored / does nothing.
    Please remove the --noatime option when using borg 1.2.
  - added a --atime option for storing files' atime into an archive

- borg command shall terminate with rc 2 for ImportErrors, #4424
- make freebsd xattr platform code api compatible with linux, #3952

Other changes:

- major setup code refactoring (especially how libraries like openssl, liblz4,
  libzstd, libb2 are discovered and how it falls back to code bundled with
  borg), new: uses pkg-config now (and needs python "pkgconfig" package
  installed), #1925

- delete: timestamp for borg delete --info added, #4359

Version 1.2.0a2 and earlier (2019-02-24)
----------------------------------------

New features:

- compact: "borg compact" needs to be used to free repository space by
  compacting the segments (reading sparse segments, rewriting still needed
  data to new segments, deleting the sparse segments).
  Borg < 1.2 invoked compaction automatically at the end of each repository
  writing command.
  Borg >= 1.2 does not do that any more to give better speed, more control,
  more segment file stability (== less stuff moving to newer segments) and
  more robustness.
  See the docs about "borg compact" for more details.
- "borg compact --cleanup-commits" is to cleanup the tons of 17byte long
  commit-only segment files caused by borg 1.1.x issue #2850.
  Invoke this once after upgrading (the server side) borg to 1.2.
  Compaction now automatically removes unneeded commit-only segment files.
- prune: Show which rule was applied to keep archive, #2886
- add fixed blocksize chunker (see --chunker-params docs), #1086

Fixes:

- avoid stale filehandle issues, #3265
- use more FDs, avoid race conditions on active fs, #906, #908, #1038
- add O_NOFOLLOW to base flags, #908
- compact:

  - require >10% freeable space in a segment, #2985
  - repository compaction now automatically removes unneeded 17byte
    commit-only segments, #2850
- make swidth available on all posix platforms, #2667

Other changes:

- repository: better speed and less stuff moving around by using separate
  segment files for manifest DELETEs and PUTs, #3947
- use pyinstaller v3.3.1 to build binaries
- update bundled zstd code to 1.3.8, #4210
- update bundled lz4 code to 1.8.3, #4209

  - switch to recent "msgpack" pypi pkg name, #3890
  - wrap msgpack to avoid future compat complications, #3632, #2738
  - support msgpack 0.6.0 and 0.6.1, #4220, #4308
