We drop it in decompressors, which are the natural next step, so if an
archive is used which isn't worldreadable (= not accessible by _apt) it
doesn't work anyway, so we just fail a bit earlier now and avoid all the
bad things which can happen over file (which could very well still be a
network resourc via NFS mounts or similar stuff, so hardly as safe as
the name might suggest at first).

As we have support for 'hold', we need support for undoing a hold which
in effect means that we implemented most other states as well, just that
they weren't exposed in the interface directly so far.
|
|
We had this code lying around in apt-mark for a while now, but other
frontends need this (and similar) functionality as well, so its high
time that we provide a public interface in libapt for this stuff.

We have a few places and there will be a few more still where we have to
call dpkg to detect/set certain features or settings. Centralizing the
calling infrastructure now seems like a good idea before we add another.

Users hold a package foo (at version X) or try to prevent the
installation of foo (usually based on the information they know about
version X), even if we say that we "hold a package". Conceptionally we
also need to know about which architecture we are talking and that is an
information bound to a version (as a package can change architecture
over time).
We internally did this lookup from Pkg to Ver already, we just move this
to a central place where the user has a change to influence it now.

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.

Some codepaths need to check if the system (in our case usually dpkg)
supports MultiArch or not. We had copy-pasted the check so far into
these paths, but having it as a system check is better for reusability.

This auto-collapses the output and doesn't run the tests

These scripts currently produce HTML output that is directly
piped into an HTML file on alioth.
There are three categories. The first two check external
library calls to use the ones specified by POSIX to be
thread-safe. The main profile excludes functions that are
thread-safe on Linux or glibc in general, while the portable
output strictly follows posix.
The internal.html output lists internal function calls, such
as configuration setting.
This is supposed to be automated further at some point, so
we can automatically check for regressions.

The former is not thread-safe, whereas the latter is.

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.

This makes non-C++11 reverse deps wishing to use it FTBFS.

This function only exists on a limited number of platforms, so
we add a configure check to make sure it exists.

This adds a vivid pinned to -1, cleans up the file a bit by
removing duplicate commands, and finally installs gettext
with a new apt-get run that is passed -t vivid.
The syntax for the pinning is some weird YAML stuff I don't
want to think about...

The acquire system actually uses usec pulse intervals, so the
previous value was correct (500ms) whereas the new value is
now 5s.
It's a bit unfortunate that the two systems use different units
for pulse intervals, but probably not much we can do about it.
This partially reverts commit eaf21c2144fa8dc4be8581dc69cf88cb38e30ce2.

This avoids churn in the po/pot files when just the location line

Now that tests can be run in parallel, lets actually do it… The mode has
some downsides like not collecting the failed tests, but it can be a lot
faster than a sequential run and is therefore a good alternative in
testing those "this shouldn't break anything" changes (which tend to
break everything if untested).

We uses a small trick to implement the fallback: We make it so, that
by-hash is a special compression algorithm and apt already knows how to
deal with fallback between compression algorithms.
The drawback with implementing this fallback is that a) we are guessing
again and more importantly b) by-hash is only tried for the first
compression algorithm we want to acquire, not for all as before – but
flipping between by-hash and well-known for each compression algorithm
seems to be not really worth it as it seems unlikely that there will
actually be mirrors who only mirror a subset of compressioned files, but
have by-hash enabled.
The user-experience is the usual fallback one: You see "Ign" lines in
the apt update output. The fallback is implemented as a transition
feature, so a (potentially huge) mirror network doesn't need a flagday.
It is not meant as a "someday we might" or "we don't, but some of our
mirrors might" option – we want to cut down on the 'Ign' lines front so
that they become meaningful – if we wanted to spam everyone with them, we
could enable by-hash by default for all repositories…
sources.list and config options are better suited for this.
Closes: 798919

This changes the semantics of the option (which is renamed too) to be a
yes/no value with the special additional value "force" as this allows
by-hash to be disabled even if the repository indicates it would be
supported and is more in line with our other yes/no options like pdiff
which disable themselves if no support can be detected.
The feature wasn't documented so far and hasn't reached a (un)stable
release yet, so changing it without trying too hard to keep
compatibility seems okay.

Not all tests work yet, most notable the cdrom tests, but those require
changes in libapt itself to have a proper fix and what we have fixed so
far is good enough progress for now.

Filenames we get could include spaces, but also the tmpdir we work in
and the failures we print in return a very generic and unhelpful…
Properly supporting spaces is a bit painful as we constructed gpg
command before, which is now moved to (multilevel) calls to temporary
scripts instead.
|

This is mostly a small speedup for the testcases, but it is also handy
to document which tests actually deal with a specific hash compared to
those which 'just' need some hash which can be important while adding
new hashes.

And of course, testing obscure things ends up showing obscure 'bugs' or
better shortcomings/inconsitencies, so lets fix them with the tests.

A bit unfair that only Bzr had this message. Lets at least print it for
git as well with the option of adding more later without string changes.

The previous implementation was still a bit unstable in terms of failing
at times. Lets try if we have more luck with this one.
