* pacman: rewrite with a cache to speed up execution
- Use a cache (or inventory) to speed up lookups of:
- installed packages and groups
- available packages and groups
- upgradable packages
- Call pacman with the list of pkgs instead of one call per package (for
installations, upgrades and removals)
- Use pacman [--sync|--upgrade] --print-format [...] to gather list of
changes. Parsing that instead of the regular output of pacman, which
is error prone and can be changed by user configuration.
This can introduce a TOCTOU problem but unless something else calls
pacman between the invocations, it shouldn't be a concern.
- Given the above, "check mode" code is within the function that would
carry out the actual operation. This should make it harder for the
check code and the "real code" to diverge.
- Support for specifying alternate package name formats is a bit more
robust. pacman is used to extract the name of the package when the
specified package is a file or a URL.
The "<repo>/<pkgname>" format is also supported.
For "state: latest" with a list of ~35 pkgs, this module is about 5
times faster than the original.
* Let fail() actually work
* all unhappy paths now end up calling fail()
* Update copyright
* Argument changes
update_cache_extra_args handled as a list like the others
moved the module setup to its own function for easier testing
update and upgrade have no defaults (None) to let required_one_of() do
its job properly
* update_cache exit path
Shift successful exit without name or upgrade under "update_cache".
It is an error if name or upgrade isn't specified and update_cache wasn't specified
either. (Caught by ansiblemodule required_one_of but still)
* Add pkgs to output on success only
Also align both format, only pkg name for now
* Multiple fixes
Move VersionTuple to top level for import from tests
Add removed pkgs to the exit json when removing packages
fixup list of upgraded pkgs reported on upgrades (was tuple of list for
no reason)
use list idiom for upgrades, like the rest
drop unused expand_package_groups function
skip empty lines when building inventory
* pacman: add tests
* python 2.x compat + pep8
* python 2.x some more
* Fix failure when pacman emits warnings
Add tests covering that failure case
* typo
* Whitespace
black failed me...
* Adjust documentation to fit implicit defaults
* fix test failures on older pythons
* remove file not intended for commit
* Test exception str with e.match
* Build inventory after cache update + adjust tests
* Apply suggestions from code review
