The width of unsigned long matching the width of a pointer isn't
guaranteed by any standard, though it is a requirement of the Linux
syscall API. Using uintptr_t directly is always correct.
This reverts commit be7d8cfaf1.
This commit missed some previous copyrights mentioned,
in general I think its better to have this per-file to
follow who wrote what and when.
This commit implements multiple performance improvements
to the transaction code:
- Don't process xbps_pkg_name() N times each time we access
its package dictionary (via pkgdb or rpool), just do it once
at xbps_pkgdb_init() time. At pkgdb init time, it just creates
a property in pkgdb, "pkgname". At rpool time, each time a
package is accessed, the "pkgname" string property is added.
- The package transaction dictionary contains the "transaction"
object to know what's the pkg type. This has been changed to an
uint8, this simplifies the logic and it's faster than checking
a string object. See xbps_trans_type_t and xbps_transaction_pkg_type().
- Fixed the issue that was marked with XXX in transaction shlibs
checking code. This has been fixed and improved and resources are
now just freed as expected.
- Simplified random code all over the place, avoiding unnecessary
allocations or operations.
- Rename some transaction files to have a better description.
This is my first rototill to the code in 2020.
`xbps_transaction_revdeps` will now try to add updates for packages to the
transaction if the dependency is not satisified anymore due to a package
install/update.
`xbps_transaction_prepare` will now check the return value of
`xbps_transaction_revdeps` and repeat the dependency resolution,
until `xbps_transaction_revdeps` returns 0, which means that it didn't
add any new packages to the transaction.
xbps_find_virtualpkg_in_conf() needs to look at the vpkgs set up in
configuration files, not from those set by pkgdb.
As a result of this the two test cases that were failing yesterday are now
fixed.
At the time we've been searching for the pkg in a repo, no repos
were registered resulting in EINVAL. While here, if there's no
declared repos return ENOENT instead.
These routines return a xbps_array_t with a full sorted dependency graph
for the target pkg, by querying pkgdb or rpool.
Update xbps-query(8) to use the new libxbps API.
- This mode prints to stdout the matching FILE stored in a binary package.
- ABI break: renamed xbps_get_pkg_plist_from_binpkg() xbps_binpkg_get_plist().
- Added xbps_binpkg_get_file() as a generic way to get pkg file contents.
- Removed useless comments from xbps_api_impl.h.
This effectively checks that all pkgs in a transaction to be installed
or updated, have not unmatched shared libraries, which might happen with
pkgs that had major soname bumps.
This implementation slow downs xbps_transaction_prepare() 2x, due to
the use of xbps_pkgdb_get_pkg_metadata(). A new pkgdb format is required
that adds the pkg shlib-provides objects to pkgdb, avoiding the need
to use xbps_pkgdb_get_pkg_metadata().
The variables to set cachedir, rootdir and metadir have been
changed to "array of chars", this way there are no extra allocations.
Update clients accordingly and bump API version.
