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
number in the source code changes.

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.

This is defined for compatibility, warning about it is intended, but
only in places where it is actually used, rather than at the place we
declare it for compatability…

Setting CXXFLAGS like --coverage on the commandline fails if we set the
std too late, so if we set it with the compiler name we set it always
first. A bit hacky as it bends the expectation, but seems to work.

The tests usually run on amd64 boxes, but once in a while I run it on a
(slow) armel box as well, which has its fair share of problems with some
tests, but at least the low hanging fruits can be dealt with: Do not
assume that amd64 is the native dpkg architecture – instead use whatever
dpkg thinks is native as architecture for the test.

Our error reporting is historically grown into some kind of mess.
A while ago I implemented stacking for the global error which is used in
this commit now to wrap calls to functions which do not report (all)
errors via return, so that only failures in those calls cause a failure
to propergate down the chain rather than failing if anything
(potentially totally unrelated) has failed at some point in the past.
This way we can avoid stopping the entire acquire process just because a
single source produced an error for example. It also means that after
the acquire process the cache is generated – even if the acquire
process had failures – as we still have the old good data around we can and
should generate a cache for (again).
There are probably more instances of this hiding, but all these looked
like the easiest to work with and fix with reasonable (aka net-positive)
effects.

Figuring out after the fact what went wrong in the kernel hook is kinda
hart, also as the bugreports are usually very lacking on the details
front. Collecting the internal variables in the debug output we attach
to the generated file might help shine some light on the matter.
It's at least not going to hurt…

In private-install.cc we call MarkInstall with FromUser=true, which sets
the bit accordingly, but while applying the EDSP solution we call mark
install on all packages with FromUser=false, so MarkInstall believes
this install is an automatic one and sets it to auto – so that a new package
which is explicitely installed via an external solver is marked as auto
and is hence also up for garbage collection in a following call.
Ideally MarkInstall wouldn't reset it, but the detection is hard to do
without regressing in other cases – and ideally ideally MarkInstall
wouldn't deal with the autobit at all – so we work around this on the
calling side for now.

The parser creates a preferences as well as an extended states file
based on the EDSP scenario file, which isn't the most efficient way of
dealing with this as thes text files have to be parsed again by another
layer of the code, but it needs the least changes and works good enough
for now. The 'apt' solver is in the end just a test solver like dump.

These assumptions were once true, but they aren't anymore, so what is
supposed to be a speed up is effectively a slowdown [not that it would
be noticible].
Usage of SingleArchFindPkg was nuked in a stable update already as the
included assumption was actually harmful btw, which is why we should get
right of other 'non-harmful' but still untrue assumptions while we can.

This is basically a rewrite of the script with the general idea of
finding the Debian version of the installed kernels – as multiple
flavours will have the same Debian version – select the two newest of
them and translate them back to versions found in package names.
This way we avoid e.g. kernel and kernel-rt to use up the protected
slots even through they are basically the same kernel (just a different
flavour) so it is likely that if kernel doesn't work for some reason,
kernel-rt will not either.
This also deals with foreign kernel packages, kernels on hold and partly
installed kernels (in case multiple kernels are installed in the same
apt run) in a hopefully sensible way.

clang detects that fd isn't set in the ReadWrite case – just that this
is supposed to be catched earlier in this method already, but it doesn't
hurt to make it explicit here as well and clang is happy, too.

As said in the bugreport, this is hardly a serious problem on a security
front, but it was always on the list to have the filename configurable
somehow and the stable filename is a problem for parallel executions.
Using an environment variable (APT_EDSP_DUMP_FILENAME) for this is more
or less the best we can do here as solvers do not get told about our
configuration and such.
