Changelog for packcheck-0.5.0

0.5.0

CI now fails if DISABLE_SDIST_BUILD is not set and the contents of the source distribution tar ball do not match the git repository contents. Either add any exceptions to .packcheck.ignore file or use DISABLE_SDIST_GIT_CHECK=y to disable this feature. Currently this check is done only if git and tar commands are available in the PATH.

cabal-v1 command now shows a deprecation message and is removed from help. This command will be removed in future.
ENABLE_INSTALL option now does nothing. This change is because of the new behavior in cabal-3. This option will be removed in future.

Added a feature to detect if any files in the git repo are missing from the source distribution tarball.
Add CABAL_PROJECT environment variable to support specifying a cabal project file.

When building from source distribution, it would not build again unless cleaned with packcheck clean if a file in the source has changed.

Deprecate and replace the cabal command with cabal-v1, in future cabal will be used for cabal-v2.
Deprecate and replace the cabal-new command with cabal-v2.
Deprecate and rename CABAL_NEWBUILD_OPTIONS to CABAL_BUILD_OPTIONS
Deprecate and rename CABAL_NEWBUILD_TARGETS to CABAL_BUILD_TARGETS
Use STACK_BUILD_OPTIONS envvar in the dependency install phase as well
Remove stack yaml creation using stack init/solver

Search for ghc among stack installed GHC binaries as well
Add GHCJS support. Use ENABLE_GHCJS=y option.
Add packcheck-safe.sh . The safe version does not trust or use any environment variables, all environment needs to be specified on the command line. It also catches any misspelled command line parameter names.
Allow boolean parameters to be specified with a lenient syntax allowing values y|Y|yes|Yes|YES|true|True|TRUE|on|On|ON|n|N|no|No|NO|false|False|FALSE|off|Off|OFF

Add a new environment var option DISABLE_DIST_CHECKS to disable source distribution checks. This can be used as a workaround for a bug in stack causing "stack sdist" to fail.
For stack builds, use the same options (STACK_BUILD_OPTIONS) for install test as for build so that an extra rebuild does not occur during install.
Workaround to avoid depending on cabal info command; in certain cases this command crashes cabal. See issue #13.

Add cabal new-build support. Use packcheck.sh cabal-new to use it.
Add knobs to disable tests or doc builds (DISABLE_TEST, DISABLE_DOCS)
Now you can specify multiple versions of GHC in PATH and packcheck automatically finds the right one based on GHCVER envvar.
Add TOOLS_DIR option to specify hvr-ghc style installation of ghc and cabal. A correct version of GHC is automatically picked from this directory.
GHCVER and CABALVER variables are now optional in travis config if you specify the cabal and ghc PPAs under apt sources.
Run autoreconf if there is a configure.ac in the package dir

Make STACK_BUILD_OPTIONS and CABAL_CONFIGURE_OPTIONS append to the existing build/configure options instead of overriding them.
Do not enforce specific stack version in CI configs - this is done to avoid failures due to github API limits when upgrading or downgrading.

Avoid build failures in cases when cabal-install has to be installed and its dependencies may conflict with the current project dependencies.

Enhancement: Nix support; fix bash location to make it work on NixOS and potentially on other systems.
