Our kernel autoremoval helper script protects the currently booted
kernel, but it only runs whenever we install or remove a kernel,
causing it to protect the kernel that was booted at that point in time,
which is not necessarily the same kernel as the one that is running
right now.
Reimplement the logic in C++ such that we can calculate it at run-time:
Provide a function to produce a regular expression that matches all
kernels that need protecting, and by changing the default root set
function in the DepCache to make use of that expression.
Note that the code groups the kernels by versions as before, and then
marks all kernel packages with the same version.
This optimized version inserts a virtual package $kernel into the cache
when building it to avoid having to iterate over all packages in the
cache to find the installed ones, significantly improving performance at
a minor cost when building the cache.

Also in old changelogs, but nothing really user visible
like error messages or alike so barely noteworthy.

This makes it easier to see which headers includes what.
The changes were done by running
git grep -l '#\s*include' \
| grep -E '.(cc|h)$' \
| xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/'
To modify all include lines by adding a space, and then running
./git-clang-format.sh.

Including cacheiterators.h before pkgcache.h fails because
pkgcache.h depends on cacheiterators.h.

If a planner lets actions to be figured out by dpkg in pending calls
these actions aren't mentioned in a simulation. While that might be
a good thing for debugging, it would be a change in behavior and
especially if a planner avoids explicit removals could be confusing for
users. As such we perform the same 'trick' as in the dpkg implementation
by performing explicitly what would be done by the pending calls.
To save us some work and avoid desyncs we perform a layer violation by
using deb/ code in the generic simulation – and further we perform ugly
dynamic_cast to avoid breaking the ABI for nothing; aptitude is the only
other user of the simulation class according to codesearch.d.n and for
that our little trick works. It just isn't working if you happen to
extend pkgSimulate or otherwise manage to call the protected Go methods
directly – which isn't very realistic/practical.

It wasn't noticeable before, but now with the (optional) logging it can
be observed that we decide in the internal path two times if an internal
or external solver should be used (and hence with logging, it is
attempted twice), so if we are in the internal path call the internal
resolver directly, which means those internal methods need to be public
– but we can hide them based on the symbol at least.

We aren't and we will not be really compatible again with the previous
stable abi, so lets drop these markers (which never made it into a
released version) for good as they have outlived their intend already.

C++11 adds the 'override' specifier to mark that a method is overriding
a base class method and error out if not. We hide it in the APT_OVERRIDE
macro to ensure that we keep compiling in pre-c++11 standards.

Doing this disables the implicit copy assignment operator (among others)
which would cause hovac if used on the classes as it would just copy the
pointer, not the data the d-pointer points to. For most of the classes
we don't need a copy assignment operator anyway and in many classes it
was broken before as many contain a pointer of some sort.
Only for our Cacheset Container interfaces we define an explicit copy
assignment operator which could later be implemented to copy the data
from one d-pointer to the other if we need it.

Some of them modify the ABI, but given that we prepare a big one
already, these few hardly count for much.

To have a chance to keep the ABI for a while we need all three to team
up. One of them missing and we might loose, so ensuring that they are
available is a very tedious but needed task once in a while.

Adding a new parameter (with a default) is an ABI break, but you can
overload a method, which is "just" an API break for everyone doing
references to this method (aka: nobody).

We are the only possible users of private methods, so we are also the
only users who can potentially export them via using them in inline
methods. The point is: We don't need these symbols exported if we don't
do this, so marking them as hidden removes some methods from the API
without breaking anything as nobody could have used them.

Previously, we had a start and a done of the calculation printed by
higher-level code, but this got intermixed by progress reporting from an
external solver or the output of autoremove code…
The higherlevel code is now only responsible for instantiating a
progress object of its choosing (if it wants progress after all) and the
rest will be handled by the upgrade code. Either it is used to show the
progress of the external solver or the internal solver will give some
hints about its overall progress. The later isn't really a proper
progress as it will jump forward after each substep, but that is at
least a bit better than before without any progress indication.
Fixes also the 'strange' non-display of this progress line in -q=1, while
all others are shown, which is reflected by all testcase changes.

Beside being a bit cleaner it hopefully also resolves oddball problems
I have with high levels of parallel jobs.

This moves the ListUpdate/AquireUpdate out of the "catch-all"
algorithm.{cc,h} file into its own update.{cc,h}
|
|
The upgrade releated code is moved into upgrade.{cc,h} and
all pkg*Upgrade* prototypes are included in algorihms.h to
avoid breaking API (unless build with APT_9_CLEANER_HEADERS).

In the past packages were flagged "Protected" so that install/
remove markings where issued before the ProblemResolver.
Nowadays, the marking methods check if they are allowed to modify
the marking of a package instead, so that markings set by FromUser
calls are not overwritten anymore by automatic calls which elimates
the need for InstallProtect which just eats CPU now.
The method itself is left untouched for now in case frontend needs it
still for some wierd usecase, but they should be eliminated.

- fix memory leak of Flags in pkgSimulate by a proper destructor
|
|
- factor out of ListUpdate a AcquireUpdate to be able to provide your
own pkgAcquire fetcher to the wrapper
|
|
- use a signed int instead of short for score calculation as upgrades
become so big now that it can overflow (Closes: #657732, LP: #917173)

The breakage is just to big for now, so guard the change with
#ifndef APT_8_CLEANER_HEADERS and be nice to library users

* [ABI-Break] merge lp:~mvo/apt/sha512-template to add support for sha512
* [ABI-Break] merge lp:~mvo/apt/dpointer to support easier extending
without breaking the ABI

- add another round of const& madness as the previous round accidently
NOT override the virtual GetCandidateVer() method (Closes: #587725)

- move the state file writting into the Go() implementation
of dpkgpm (closes: #498799)

- fix simulation performance drop (thanks to Ferenc Wagner
for reporting the issue)
