* the solver no longer does look-ahead locking of names
(could be possibly optimized later); instead names are now
always ordered strictly to properly detect the package names
which are unsolveable
* basic error tests added, so we can see the most likely problem
in dependencies easily
* 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 indexer keep noise about errors that prevent index generation.
Detect certain errors in the APKs better. And also have the applet
return error in these scenarios.
commit 4e72075fba introduced a bug where package installation might happen
in wrong order (reminder for self to separate the package version deduction
to separate step from installation ordering). this restricts the earlier
commit to not mingle with the install order.
Our build infra does not yet handle properly noarch, so for the
time being we will rewrite them as native packages in index. This
allows the package to be fetched from the proper URL. This feature
will be removed once abuild and the build infra handle noarch
properly.
commit 4e72075fba introduced late locking for top level packages,
but used the wrong package's top level flag for the check. this
fixes a problem that dependencies might not get pulled in.
move all files therein to other places. this allows /var to be
mounted from harddisk, but rest of system be run from ramdisk.
this also removes support for historical version of the scripts
database which was obsoleted in 2.0_pre16 (in July 2009).
If GNU wget is available, then we want use it as it gives the user
possibility to set misc options, such as bandwidth limit in wgetrc.
It might also be that busybox is not available in case bootstrapping
alpine from other distros (think debian vserver host creating an
alpine guest)
In any case we, fall back to busybox wget in case wget libs are getting
upgraded. (see http://redmine.alpinelinux.org/issues/347)
