• Expose Rsync_store module (@MisterDA #114, reviewed by @talex5)
• Rsync hard-links to save space (@art-w #102, reviewed by @patricoferris)

v0.4

• Use GNU tar format instead of UStar for copy operations (@TheLortex #82, reviewed @dra27). This enables copying from sources containing long file names (>100 characters).
• Add support for secrets (@TheLortex #63, reviewed by @talex5). The obuilder spec's run command supports a new secrets fields, which allows to temporarily mount secret files in an user-specified location. The sandbox build context has an additional secrets parameter to provide values for the requested keys.
• Limit permissions on temporary directories (@talex5 #67)
• Check Linux kernel version support for btrfs (@kit-ty-kate #68)
• Generalise obuilder sandbox, removing runc/linux specifc pieces and making the S.SANDBOX interface more general (@patricoferris #58, reviewed by @talex5, @avsm, @MisterDA)
• Convert --fast-sync back to a flag (@talex5 #72)
• Support Fmt.cli and Logs.cli flags. (@MisterDA #74, reviewed by @talex5) For Fmt the new options are --color=always|never|auto For Log the new options are: -v, --verbose Increase verbosity --verbosity=LEVEL (absent=warning) Be more or less verbose. LEVEL must be one of quiet, error, warning, info or debug. Takes over -v.
• Minor cleanup changes (@talex5 #76)
• Fix deprecations in Fmt 0.8.10 (@tmcgilchrist #80)
• Remove travis-ci and replace with Github Actions (@MisterDA #84)
• Add RSync store backend for obuilder to support macOS builders (@patricoferris #88, reviewed @talex5)
• Fixes for ZFS tests in CI (@patricoferris #91)

v0.3

Security fix:

• resolv.conf file should be mounted read-only.

Other changes:

• Make Os and Db modules private. Move the env type to Config, as that is used externally.
• Fix license. It was copy-pasted from OCurrent, and still mentioned that project's lib_ansi library.
• Require obuilder-spec package to be same version.

v0.2

• Add support for nested / multi-stage builds (@talex5 #48 #49). This allows you to use a large build environment to create a binary and then copy that into a smaller runtime environment. It's also useful to get better caching if two things can change independently (e.g. you want to build your software and also a linting tool, and be able to update either without rebuilding the other).

• Add healthcheck feature (@talex5 #52).

  • Checks that Docker is running.
  • Does a test build using busybox.
• Clean up left-over runc containers on restart (@talex5 #53). If btrfs crashes and makes the filesystem read-only then after rebooting there will be stale runc directories. New jobs with the same IDs would then fail.
• Remove dependency on dockerfile (@talex5 #51). This also allows us more control over the formatting (e.g. putting a blank line between stages in multi-stage builds).
• Record log output from docker pull (@talex5 #46). Otherwise, it's not obvious why we've stopped at a pull step, or what is happening.
• Improve formatting of OBuilder specs (@talex5 #45).
• Use seccomp policy to avoid necessary sync operations (@talex5 #44). Sync operations are really slow on btrfs. They're also pointless, since if the computer crashes while we're doing a build then we'll just throw it away and start again anyway. Use a seccomp policy that causes all sync operations to "fail", with errno 0 ("success"). On my machine, this reduces the time to apt-get install -y shared-mime-info from 18.5s to 4.7s. Use --fast-sync to enable to new behaviour (it requires runc 1.0.0-rc92).
• Use a mutex to avoid concurrent btrfs operations (@talex5 #43). Btrfs deadlocks enough as it is. Don't stress it further by trying to do two things at once.

Internal changes:

• Improve handling of file redirections (@talex5 #46). Instead of making the caller do all the work of closing the file descriptors safely, add an FD_move_safely mode.
• Travis tests: ensure apt cache is up-to-date (@talex5 #50).

v0.1

Initial release.
