done on the mirco-optimazation level, so lets fix them:
(performance) Possible inefficient checking for emptiness.
(performance) Prefer prefix ++/-- operators for non-primitive types.

broken policy state by the upgrade

use the internal resolver can now be used also with external
ones as the usage is hidden in between the old API
* provide two edsp solvers in apt-utils:
- 'dump' to quickly output a complete scenario and
- 'apt' to use the internal as an external resolver
|
|
for the three different dependencies
|
|
|
|
|
|
and instead rely on the Autoremove tagging to show us what could be done.
(apt-internal-solver doesn't support this currently as it doesn't load
the auto-information into the cache)
|
|
|
|
solver in this list of directories
|
|
|
|
The solution is NOT interpreted so far.
|
|
|
|
just writing stuff… it also reads and can work for both:
- APT talking to an external solver
- an external solver (understanding EDSP) talking to APT
|
|
|
|
|
|
based on a very early draft for EDSP by Stefano
APT can now write a scenario as well as load most stuff from it.

Multi-Arch; instead, Arch: all packages only satisfy dependencies for
the native arch, except where the Arch: all package is declared
Multi-Arch: foreign. (Closes: #613584)
This has the sideeffect that arch:all packages internally show up as
coming from the native arch - so packages with the architecture "all"
doesn't exist any longer in the pkgcache

* merged lp:~evfool/apt/fix418552:
- Grammar fix for bug LP: #418552, thanks to Robert Roth
|
|
- mark pseudo packages of installed all packages as configured
in the simulation as we don't call configure for these packages
|
|
- mark all installed packages first without auto installation in
a dist-upgrade to prefer upgrading packages instead of installing
new packages in versioned or-groups (Closes: #605394)
|
|
- if the package was explicitly marked as ToRemove don't
consider it as a candidate for FixByInstall
|
|
conflicts/breaks against virtual packages (LP: #614993)
|
|
|
|
|
|
DpkgBreaks, make sure to break in the loop (just like for a conflict)
|
|
Start.AllTarget() returns all non-canidates as well, we want to filter them out
|
|
|

- let the problem resolver install packages to fix or-groups
as a needed remove nuked another or-member (helps for #591882)
The resolver sometimes need to break or-groups because he need to
remove the previous satisfier as a result of a breaks/conflicts.
In such broken or-groups he now tries to install a non-installed
non-deleted member of the or-group to statisfy it again.
This move is dangerous as it introduces the possibility of a
bunch of "new" broken breaks/conflicts on the new statisfier or
its dependencies and we don't know about them beforehand.
We also don't have the infrastructure to undo the decision later,
so we just do it and pray!
For now a test option is provided to disable this behavior on the
fly to test if the situation is worse: pkgProblemResolver::FixByInstall

- change the debug outputs to display also arch of the
package and version dependencies information
|
|
- on gpg verification failure warn and restore the last known
good state
- on failure display the IP of the server (useful for servers
that use round robin DNS)
- support Original-Maintainer in RewritePackageOrder
- enable cdrom autodetection via libudev by default
- show messsage about Vcs in use when apt-get source is run for
packages maintained in a Vcs
- better support transitional packages with mark auto-installed.
when the transitional package is in "oldlibs" the new package
is not marked auto installed (same is true for section
metapackages)
- provide new "deb mirror://archive.foo/mirrors.list sid main"
method expects a list of mirrors (generated on the server e.g.
via geoip) and will use that, including cycle on failure
- write apport crash file on package failure (disabled by default
on debian until apport is available)
- support mirror failure reporting (disabled by default on debian)
|
|
- add a parent-guarded "mkdir -p" as CreateDirectory()
* apt-pkg/acquire.{cc,h}:
- add a delayed constructor with Setup() for success reporting
- check for and create directories in Setup if needed instead of
error out unfriendly in the Constructor (Closes: #523920, #525783)
- optional handle a lock file in Setup()
* cmdline/apt-get.cc:
- remove the lock file handling and let Acquire take care of it instead

Arch all packages are now represented by arch depending packages which
all depend on a package with the same name and the special arch "all".
This packages has NO dependencies, but beside this the same information.
It is the only package which has a size, the arch depending ones all
have a zero size. While the arch depending pseudo packages are used
for dependency resolution the arch "all" package is used for downloading
and ordering of the package.

* add hook for MarkInstall and MarkDelete (closes: #470035)
* add the various foldmarkers in apt-pkg & cmdline (no code change)
* versions with a pin of -1 shouldn't be a candidate (Closes: #355237)
* prefer mmap as memory allocator in MMap instead of a static char
array which can (at least in theory) grow dynamic
* eliminate (hopefully all) segfaults in pkgcachegen.cc and mmap.cc
which can arise if cache doesn't fit into the mmap (Closes: #535218)
* display warnings instead of errors if the parts dirs doesn't exist
* honor the dpkg hold state in new Marker hooks (closes: #64141)

- make the max pipeline depth of the acquire queue configurable
via Acquire::Max-Pipeline-Depth
* apt-pkg/deb/dpkgpm.cc:
- add Dpkg::UseIoNice boolean option to run dpkg with ionice -c3
(off by default)
- send "dpkg-exec" message on the status fd when dpkg is run
- provide DPkg::Chroot-Directory config option (useful for testing)
- fix potential hang when in a backgroud process group
* apt-pkg/algorithms.cc:
- consider recommends when making the scores for the problem
resolver
* apt-pkg/acquire-worker.cc:
- show error details of failed methods
* apt-pkg/contrib/fileutl.cc:
- if a process aborts with signal, show signal number
* methods/http.cc:
- ignore SIGPIPE, we deal with EPIPE from write in
HttpMethod::ServerDie() (LP: #385144)
* apt-pkg/indexcopy.cc:
- support having CDs with no Packages file (just a Packages.gz)
by not forcing a verification on non-existing files
(LP: #255545)
- remove the gettext from a string that consists entirely
of variables (LP: #56792)
* apt-pkg/cacheiterators.h:
- add missing checks for Owner == 0 in end()
* apt-pkg/indexrecords.cc:
- fix some i18n issues
* apt-pkg/contrib/strutl.h:
- add new strprintf() function to make i18n strings easier
- fix compiler warning
* apt-pkg/deb/debsystem.cc:
- make strings i18n able
* fix problematic use of tolower() when calculating the version
hash by using locale independant tolower_ascii() function.
Thanks to M. Vefa Bicakci (LP: #80248)
* build fixes for g++-4.4
* cmdline/apt-mark:

* document --install-recommends and --no-install-recommends
(thanks to Dereck Wonnacott, LP: #126180)
* Updated cron script to support backups by hardlinks and
verbose levels. All features turned off by default.
* Added more error handlings. Closes: #438803, #462734, #454989,
* Refactored condition structure to make download and upgrade performed
if only previous steps succeeded. Closes: #341970
* Documented all cron script related configuration items in
configure-index.
* apt-ftparchive might write corrupt Release files (LP: #46439)
* Apply --important option to apt-cache depends (LP: #16947)

* honor the dpkg hold state in new Marker hooks (closes: #64141)
Combine the proposed AutoInstOk and IsAutoInstallOk to more general hooks
for MarkInstall (and another one for MarkDelete) with the same parameters
as the call these hooks should check.
|
|
|
|
|
|
* honor the dpkg hold state in IsAutoInstallOk (closes: #64141)
|
|
* add Debug::pkgProblemResolver::ShowScores and make the scores
adjustable
|
|
- consider recommends when making the scores for the problem
resolver
