Previous implementation was somewhat working in the most) scenarios, but
was super slow to handle permissions. However, it is actually very
limited operations in which the application can do anything, so it is
much easier to just drop privileged user to normal one
It has been found that during cold start (e.g. in docker container),
some permissions are invalid. In order to handle that, some operations
are not guarded with RepositoryPaths.preserve_root guard
In addition, it has been also found that in some cases (e.g. web server
start) migrations are performed on empty repository identifier which may
lead to wrong data (see also 435375721d),
as well as some unexpected results during database operations. In order
to handle that, now all watcher instances have their own databases (and
configurations)
(#150)
Current implementation did it in wrong way. First of all, there was a
lookup through pkgbase instead of pkgname, which lead to errors, because
aur api doesn't allow to search by pkgbase (as well as provides is
basically pkgname instead)
It also was found that dependencies resolution lookup has been performed
by using raw packages array, which can include versions, descriptions
etc
This commit includes the following changes
* Bump github actions
* Update tests github action to check documentation and streamline
process
* Update test cases to use temporary directories as roots
* Simplify tox.ini
After the last updates, tests produce warnings that the connection to
database is leaked, which appears to be correct. This commit changes
behaviour to closing connection explicitly via contextlib
