Git-Dch: Ignore
|

As usual by now, not all containers wrapped by the cacheset containers
support all methods, like push_back now, but they fail on use of these
unusable methods only.
Would be nice to not expose these methods for unsupporting containers at
all, but that means either a lot of classes or a lot of std::enable_if
magic, which seems like too big work for this small wrapper for now.

Technically an abi-break as we change a template parameter to
std::iterator for this, but this class is empty in all instances and
just causes the right typedefs to be set – which were incorrect as
detected by std::stable_partition as its implementation uses ::pointer
and needs also a operator* implementation.
In practice CacheSets have no external users (yet) and the difference is
visible only at compile time (which was an error before and now works),
not while linking.
The changes to apt-mark are functionally identical to the code before,
just that we use a std:: algorithm now instead of trying hard on our
own.

Since gcc 4.9, the API for erase slightly changed. In
commit 3dddcdf2432e78f37c74d8c76c2c519a8d935ab2 the
existing checks for __cplusplus where changed to
check the gcc version, as the __cplusplus check
did nothing, because gcc 4.8 already provided the
standard value in there.
Fix the code to check for the gcc version in two
more places, and change the existing checks to
use a convenience macro.

With a bit of trickery and the Curiously recurring template pattern we
can free us from our use of virtual in the iterators were it is unneeded
bloat as we never deal with pointers to iterators and similar such.

Further abstracting our new ShowList allows to use it for containers of
strings as well giving us the option to implement an or-groups display
for the recommends and suggests lists which is a nice trick given that
it also helps with migrating the last remaining other cases of old
ShowList.
|

apt-get is displaying various lists of package names, which until now it
was building as a string before passing it to ShowList, which inserted
linebreaks at fitting points and showed a title if needed, but it never
really understood what it was working with. With the help of C++11 the
new generic knows not only what it works with, but generates the list on
the fly rather than asking for it and potentially discarding parts of
the input (= the non-default verbose display). It also doubles as a test
for how usable the CacheSets are with C++11.
(Not all callers are adapted yet.)

By further abstracting the iterator templates we can wrap the reverse
iterators of the wrapped containers and share code in a way that
iterator creating is now more template intensive, but shorter in code.

The "problem" is mostly in the erase() definitions as they slightly
conflict and in pre-c++11 are not uniformly in different containers.
By differenciating based on the standard we can provide erase() methods
for both standards – and as the method is in a template and inline we
don't need to worry about symbols here.
The rest is adding wrappings for the new forward_list and unordered_set
containers and correcting our iterators to use the same trait as the
iterator they are wrapping instead of having all of them be simple
forward iterators. This allows the use of specialized algorithms which
are picked based on iterator_traits and implementing them all is simple
to do as we can declare all methods easily and only if they are called
they will generate errors (if the underlying iterator doesn't support
these).

C++11 slightly changes the API again to const_iterator, but we are find
with iterators in the C++03 style for now as long as they look and
behave equally to the methods of the standard containers.

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.
Git-Dch: Ignore
|

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.

For compatibility we use/provide and fill quiet some deprecated methods
and fields, which subsequently earns us a warning for using them. These
warnings therefore have to be disabled for these codeparts and that is
what this change does now in a slightly more elegant way.

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.
Git-Dch: Ignore

The methods itself deal with the helper a lot, so it makes sense to move
them to the helper itself, which helps also if we want to override some
of these methods, the FromString mentioned in the bugreport being the
obvious example.
VCI is spared from this change for now as while it would fit with the
same reasoning it much heavier entangled with the previous
CacheSetHelper change, so moving it now would mean breaking the API.
The PCI change is worthwhile on its own though as it is used by VCI.
Closes: 686221

The introduction of Fnmatch showed that each new selector would require
multiple new virtual methods in the CacheSetHelper to work correctly,
which isn't that great. We now flip to a single virtual method which
handles all cases separated by an enum – as new enum values can be added
without an ABI break.
Great care was taken to make old code work with the new way of organisation,
which means in return that you might be bombarded with deprecation
warnings now if you don't adapt, but code should still compile and work
as before as can be seen in apt itself with this commit.

A version belongs to a section and has hence a section member of its
own. A package on the other hand can have multiple versions from
different sections. This was "solved" by using the section which was
parsed first as order of sources.list defines, but that is obviously a
horribly unpredictable thing.
We therefore directly remove this struct member to free some space and
mark the access method as deprecated, which is told to return the
section of the 'newest' known version, which is at least predictable,
but possible not what it returned before – but nobody knows.
Users are way better of with the Section() as returned by the version
they are dealing with. It is likely the same for all versions of a
package, but in the few cases it isn't, it is important (like packages
moving from main/* to contrib/* or into oldlibs …).

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

with g++-4.1 it complains about this so lets be extra clear

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

* cmdline/apt-{get,cache,mark}.cc:
- use Lists instead of Sets if input order should be preserved for
commands accepting lists of packages, e.g. policy (Closes: #625960)
|
|
- make the cachesets real containers which can embedding any container
to be able to use the same interface regardless of set or list usage

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
|
|
* cmdline/apt-cache.cc:
- use Notice instead of Error in the CacheSetHelper messages
for compat reasons. Otherwise tools like sbuild blow up
|
|
- move them back to the library as they look stable now
|
|
- doesn't include it in the library for now as it is too volatile
