* basic code for a backtracking, forward checking dependency satisfier
* works better when there are tricky dependencies to solve
(when can't just upgrade everything to most preferred versions)
* the new code always evaluates all of 'world' constraints
(old code just does incremental updates based on heuristics)
* is probably somewhat slower than old code (probably unnoticeable
difference in most cases)
* makes easier to write support for provides and repository pinning
* test applet and a bunch of test cases added which uses the new code
* from the old feature set install_if is not yet implemented
This applet can be used to generate data for graphviz tools.
Useful to visualize package dependencies, and possible errors
in the repository.
Usage examples:
apk dot gnome-desktop | tred | dot -Tpng gnome-desktop.png
-- to generate simplified dependency chart of gnome-desktop
apk dot --errors | dot -Tpng index-errors.png
-- to generate chart visualizing dependency errors in index
Make the libapk and lua module optional at buildtime and off by default.
This is because enabling libapk requires that mkinitfs also copies the
libapk.so or the initramfs will not work.
To build libapk:
make LIBAPK=yes
To build lua module (will enable LIBAPK=yes):
make LUAAPK
To link apk to libapk (will enable LIBAPK=yes):
make SHARED_LIBAPK=yes
All the above applies to make install target as well.
Instead of having a null pointer, use a dummy array which just
says the array is empty. This helps in multiple places of the code
which would otherwise need explicitly need to check first if the
array exists. This has been cause of multiple seg.faults in the
past as the array check is easily omitted.
This also removes (or fixes) all existing checks accordingly.
this way we never change cwd, and relative filenames are always
parsed consistently. this also helps filename construction in many
places. this patch also changes '--root' to override location of
all configuration to be in the new root. previously it depended
on the file which one was used.
use pkgconfig of zlib instead of hard requiring it. and link in
the pkg-config libs with --as-needed as not all of the openssl
libs are really required.
Tracks now probler header file dependencies and command line parameters
used to build files. E.g. changing CFLAGS rebuild all C-files. And changing
version rebuild now the files where it's used.
Currently only implement --backup to get list of (config) files in
protected directories to backup.
This also fixes a database corruption bug in database.c.
