Changelog for B9

1.1.0

• Fix unintended deletion of images that are wrongly classified as obsolete.
• Add a configuration parameter for guarding operations, for which no timeout values was specified: default_timeout_seconds.
• Introduce a configuration parameter to specify an optional timeout factor. Since the introduction of SystemdNspawn support, most invokation of external system commands, e.g. mount, are guarded by short timeouts. During testing I discovered that some systems are just slower and might run into a timeout. To mitigate that, a user can now configure a timeout factor that is applied to the internal, hard-coded time values.
• Change NIX expressions to use haskellPackages instead of myHaskellPackages.

1.0.1

• Improve nix build expressions

0.5.69.0

• Add new ImageResize option ShrinkToMinimumAndIncrease
• Remove the byte unit from SizeUnit
• Add new utility functions to B9.DiskImages for image size calculations

0.5.68.3

• Fix issue #10: The CLI parameter --network host is ignored
• Flush the log output after every log message to stdout

0.5.68.2

• Fix a bug in the shared image Shake rule causing unnecessary rebuilds

• Remove Trying to load config file messages

• Fix #8 - resurrect the environment variable buildDirRoot.

0.5.68

• Allow version specific config file resolution

  B9 changes the config file format from time to time. To enable simultaneous use of different B9 versions with conflicting config file formats the user may provide version specific default config files, and B9 will prefer the file matching its own version most closely.

  When loading its config file, B9 will now look for, and prefer config files suffixed with the longest matching version.

  For example: If B9 has version 0.5.68 these config files will be tried:

  • ~/.b9/b9.conf.0.5.68
  • ~/.b9/b9.conf.0.5
  • ~/.b9/b9.conf.0
  • ~/.b9/b9.conf

  If custom config file path are passed to B9 they will be tried first, and also with the version appended. For example, when runing b9c -c other-config-path list these paths would be tried:

  • other-config-path.0.5.68
  • other-config-path.0.5
  • other-config-path.0
  • other-config-path
  • /home/sven/.b9/b9.conf.0.5.68
  • /home/sven/.b9/b9.conf.0.5
  • /home/sven/.b9/b9.conf.0
  • /home/sven/.b9/b9.conf

0.5.67

• Iron out UTF-8 decoding issues

  • Use Data.Text in more places

  • Remove ByteStringGenerator

  • Change ToContentGenerator to produce only (strict) Data.Text.Texts

• Add B9.Text a module with conversion functions for different string types.

• Add helper functions and type for Erlang parsing:

  • textToErlangAst,

  • stringToErlangAst and

  • ErlangAST

0.5.66

• Fix the Nix package:

  • Get rid of the virsh path configuration item

  • Allow setting the path to @/.../libexec/libvirt_lxc@ via environment variable

0.5.65

• Refactor the B9 Monad to use extensible-effects

0.5.64

• Refactor and prepare for more drastic changes

• Fix runtime errors due to undefined values in the environment

0.5.63

• Depend on shake-0.17.6 to fix build errors

0.5.62

• Rewrite B9.Shake.SharedImageRules in line with Shake's example for custom rules

• Replace ConcatableSyntax by using Binary instances, and also

  • Remove/Inline encodeSyntax by using Binary.encode

  • Rename decodeSyntax to decodeOrFail' and delegate to Binary.decodeOrFail.

• Add a newtype wrapper around YamlObject for cloud-init yaml documents CloudConfigYaml

  This new type serves the purpose of add the #cloud-config line to the top of the generated yaml document, as required by cloud-init.

  The Binary instance adds this header line and delegates the rendering of the yaml document to YamlObject.

• Remove the rendering of this header line in the YamlObject Binary instance.

• Rename RenderYaml to RenderYamlObject In order to prevent unexpected runtime behaviour in code that uses this library.

• Introduce the type Environment that replaces the ubiquotus [(String, String)] by a lazy Text based HashMap.

• Add addLocalPositionalArguments

• Rename the previous B9.Artifact.Content to B9.Artifact.Content

• Introduce ContentGenerator as an open, extensible alternative to Content, AST and CanRender in the module B9.Artifact.Content

• Rename-and-Split refactor B9.ArtifactSource{Impl} to B9.Artifact.Generator.{..}

• Move CanRender from B9.Artifact.Content.AST to B9.Artifact.Content

• Switch to lazy Texts and ByteStrings where possible, since B9 might read/generate large files.

• Rename CanRender to ToContentGenerator and change the method signatur to return the new ContentGenerator type

• Fix spelling: Rename B9Invokation to B9Invocation

• Rename FromAST to FromAST

• Rearrange modules for content generation:

  • Introduce Content.FromByteString

  • Remove deprecated Concatenation
