We use a wild mixture of C and C++ ways of generating output, so having
a consistent world-view in both styles sounds like a good idea and
should help in preventing regressions.
|
|
|

Using C++ here avoids calling setlocale here which never really was that
ideal, but needed to avoid locale specific weekday/month names.
|

HTTP/1.1 hardcodes GMT (RFC 7231 §7.1.1.1) and what is good enough for the
internet must be good enough for us™ as we reuse the implementation
internally to parse (most) dates we encounter in various places like the
Release files with their Date and Valid-Until header fields.
Implementing a fully timezone aware parser just feels too hard for no
effective benefit as it would take 5+ years (= until LTS's are out of
fashion) until a repository could use non-UTC dates and expect it to
work. Not counting non-apt implementations which might or might not
only want to encounter UTC here as well.
As a bonus, this eliminates the use of an instance of setlocale in
libapt.

Setting the C++ locale via std::locale::global(std::locale("")); which
would otherwise default to the default C locale (aka: unaffected by
setlocale) effects the formatting of numeric types in IO streams, which
for output for humans is perfectly sensible, but breaks our many text
interfaces used and parsed by us and others without expecting the
numbers to be formatted.

libapt allows to configure compressors to be used by its system via
configuration implemented in 03bef78461c6f443187b60799402624326843396,
but that was never really documented and also only partly working, which
also explains why the tests weren't using it…

The debian/rules file tries to guess in which directory it is supposed
to be building, but that guess is always ./build – if it wasn't it
would fail later as not all rules take alternatives into acount.
So, as this is clearly not used lets remove this complexity instead of
fixing it up.

The embedding is done completely automatic by doxygen and documented to
be that way for reasons: /usr/share/doc/doxygen/README.jquery
As we can't do anything about it, it is pointless to keep the warning.

The code moving in eb1f04dda07c2b69549ad9fd793cca0e91841b3e
moved the acquire stuff above the simulation exit, so before getting
locks (and creating/chmod directories) we should be checking if we
should actually really do it…

No real code change, just moving code around heavily to decouple the
EDSP specific parts from those we can reuse for EDSP-like protocols.

Its more space and runtime efficient to use a boolean set instead of a
CacheSet-based implementation.

This allows to differentiate properly between 'apt-get upgrade', 'apt

Using a std::array to silence gcc as well as as a code improvement feels right here.

The &= introduced in the EDSP-FileFd conversion isn't working to full
satisfaction for multiple && clauses as the && has a higher binding than
&= has, so that the methods were called even through they shouldn't
have because of previous errors. Using variadic functions we can solve
this in a slightly cleaner way bringing down the amount of 'broken pipe'
errors for the error case of the dump resolver substantially.

I doubt there is any non-src:apt usage of these interfaces.

The report mentions "apt list --upgradable", but there are others which
have inconsistent behavior ranging from segfaulting to doing something
with the partial (and hence incomplete) data. We had a recent report
about sources.list (#818628), this one mentions prefences, the obvious
next step is conf files… so the testcase is adapted to check for all
three in file and directory versions and run a bunch of commands each
time which should all have more or less the same behavior in such a case
(aka error out).

--show-upgraded is the default since
906fbf8886926eeb302332d997c9bd861291e155 so documenting it as if it
would be an option having an effect as is feels wrong and we do the same
for other options like install-recomends, download, …, too.
This commit also removes -u from the documentation, but still supports
it in the commandline parsing. Eventually we should deprecate the short
option, but for now lets just stop documenting it.

This commit moves the creation of the fetcher and with it the
calculation of the filenames before the code generation the various
lists detailing the solution. This means that simulation comes even so
slightly closer to a real run as it will require and parse the package
indexes for filenames and queuing of URIs, so that a simulation "using"
an unavailable download method actually fails now.
The real benefit of this change is through that the rather special but
nontheless handy --no-download --fix-missing mode now actually shows
what the solution is it will apply to the system rather than the
solution it would if it could download all not-downloaded packages.

Errors cause a kind of automatic no already, but warnings and notices
are only displayed at the end of the apt execution even through they
could effect the choice of saying yes/no to questions: E.g. if a
configuration (file) was ignored you wanted to have an effect or if an
external solver you used generated warnings suggesting that the solution
might be valid, but bogus non-the-less and similar things.
Note that this only moves those messages up to the question if the
answer is interactive – not if e.g. -y is used or no question is asked at
all so this has an effect only on interactive usage of apt(-get), not
script who might be parsing apt output.

This fixes comparisons where either the stored or the input string
have a trailing comma.

This hopefully makes debugging things easier.

The rest is also on the same line, so let's go consistent here
now that we have a bug report about it.

This fixes Debian/apt#13 and the launchpad bug listed below,
but is far more advanced. I went through private-cmndline.cc
and looked at the supported options.

Unexpected are for examples removal requests for versions which aren't
installed, installations of already installed versions & requests to
install and remove a package at the same time.
|
|
Document that package identifiers must be unique (apt only uses the last
action for a given identifier) and that install requests do also imply
upgrades and downgrades (and thus removal of the old version). This is
to prevent that solvers express an upgrade or downgrade instruction as
two stanzas: a removal of the old version and an installation of the new
version. Instead, a single install stanza is sufficient to express
upgrade or downgrade requests.

The spec was slightly inconsistent if the preferences setting is
available only as generic or specific setting & the code only supported
the specific one, while for the strict-pinning was only generic…
As the usual pattern for apt is to have both options we adapt the spec
and code to support both as well.
This also adds a purely informal "Solver" field so in case the request
is saved in a file, we know to which solver the sent preferences apply.
Closes: 823918

Failures can happen and APT regardless will do a partial cache
update anyway. Because APT ensures that the list directory is
in a sane state, it makes sense to also call success hooks if
success was only partial - otherwise it loses sync with APT.
Most importantly, this causes the appstream cache to be empty,
see launchpad bug #1562733.
This is somewhat overly optimistic though: As soon as any repository
has nonexisting optional files, the missing optional files are also
treated as success, which means a single broken repository without an
InRelease file still runs Success hooks, even though it really should
not.

This prevented some sources.list entries from working, an example
of which can be found in the test.

Improve GetLocalitySortedVersionSet, speeds up apt search by 30%

Versions which are only available in dpkg/status aren't installable and
apt doesn't pick them as candidate for this reason – for the same reason
such packages shouldn't be sent to an external solver via EDSP. The
packages are pinned to -1, but if the solver has strict pinning disabled
it could end up picking this version anyhow – which is a request apt can
not satisfy.

gpg doesn't give use a UID on NODATA, which we were "expecting" (but not
using for anything), but just an error number. Instead of collecting
these as badsigners which will trigger a "invald signature" error with
remarks like "NODATA 1" we instead adapt a message similar to the NODATA
error of a clearsigned file (which is actually not reached anymore as we
split them up, which fails with a NOSPLIT error, which uses the same
general error message).
In other words: Not a security relevant change, just a user experience
improvement as we now point them to the most likely cause of the
problem instead of saying "invalid signature" which would point them in
the direction of the archive being broken (for everyone) instead.

A frontend like apt-file is only interested in a specific set of files
and selects those easily via "Created-By". If it supports two locations
for those files through it would need to select both and a user would
need to know that implementation detail for sources.list configuration.
The "Identifier" field is hence introduced which by default has the same
value as "Created-By", but can be freely configured – especially it can
be used to give two indexes the same identifier.

Sometimes index files are in different locations in a repository as it
is currently the case for Contents files which are per-component in
Debian, but aren't in Ubuntu. This has historic reasons and is perhaps
changed soon, but such cases of transitions can always happen in the
future again, so we should prepare:
Introduced is a new field declaring that the current item should only be
downloaded if the mentioned item wasn't allowing for transitions without
a flagday in clients and archives.
This isn't implemented 'simpler' with multiple MetaKeys as items (could)
change their descriptions and perhaps also other configuration bits with
their location.

It looks a bit strange on the outside to have multiple "native
architecture", but all is considered an implementation detail and e.g.
packages of arch:all are in dependency resolution equal to native
packages.

We don't have to initialize the Release files with a set of IndexTargets
to acquire, but instead wait for the Release file to be acquired and
only then ask which IndexTargets to get.

Progress reporting used an "upper bound" on files we might get, expect
that this wasn't correct in case pdiff entered the picture. So instead
of calculating a value which is perhaps incorrect, we just accept that
we can't tell how many files we are going to download and just keep at
0% until we know. Additionally, if we have pdiffs we wait until we got
these (sub)index files, too.
That could all be done better by downloading all Release files first and
planing with them in hand accordingly, but one step at a time.

The code naturally evolved from a TransactionManager optional to a
required setup which resulted in various places doing unneeded checks
suggesting a more complicated setup than is actually needed.
