The default buffer size for pkgTagFile is 32kb which should be big
enough for everything… expect for enormous lists of provides,
resulting in:
$ apt show librust-winapi-dev
E: Unable to parse package file /var/lib/apt/lists/ftp.br.debian.org_debian_dists_unstable_main_binary-amd64_Packages (2)
E: Internal Error, Unable to parse a package record
The "apt-cache show" codepath uses instead a max size for all files,
which seems a bit excessive, but works – using the max size for the file
in question seems most appropriate.
The patch is written for the 1.6.y series as a rewrite of the related
code in the 1.7.y series (commit bf53f39c9a0221b670ffff74053ed36fc502d5a0)
removed this problem before it was reported.
Closes: #905527
LP: #1787120

Installed-Size for linux-image-4.13.0-1-amd64-dbg and friends
are larger than 4 GB, but read as a signed integer - that's
fine so far, as the value is in KB, but it's multiplied with
1024 which overflows. So let's read it as unsigned long long
instead.
While we're at it, also use unsigned long long for Size, in
case that is bigger than 2 GB.

This doesn't allow all tests to run cleanly, but it at least allows to
write tests which could run successfully in such environments.

We do not show the architecture as a dedicated field as this is rather
technical information, but as packagename it makes sense to show the
architecture as other part of apt will refer to it in this way.

Based on a discussion with Niels Thykier who asked for Contents-all this
implements apt trying for all architecture dependent files to get a file
for the architecture all, which is treated internally now as an official
architecture which is always around (like native). This way arch:all
data can be shared instead of duplicated for each architecture requiring
the user to download the same information again and again.
There is one problem however: In Debian there is already a binary-all/
Packages file, but the binary-any files still include arch:all packages,
so that downloading this file now would be a waste of time, bandwidth
and diskspace. We therefore need a way to decide if it makes sense to
download the all file for Packages in Debian or not. The obvious answer
would be a special flag in the Release file indicating this, which would
need to default to 'no' and every reasonable repository would override
it to 'yes' in a few years time, but the flag would be there "forever".
Looking closer at a Release file we see the field "Architectures", which
doesn't include 'all' at the moment. With the idea outlined above that
'all' is a "proper" architecture now, we interpret this field as being
authoritative in declaring which architectures are supported by this
repository. If it says 'all', apt will try to get all, if not it will be
skipped. This gives us another interesting feature: If I configure a
source to download armel and mips, but it declares it supports only
armel apt will now print a notice saying as much. Previously this was a
very cryptic failure. If on the other hand the repository supports mips,
too, but for some reason doesn't ship mips packages at the moment, this
'missing' file is silently ignored (= that is the same as the repository
including an empty file).
The Architectures field isn't mandatory through, so if it isn't there,
we assume that every architecture is supported by this repository, which
skips the arch:all if not listed in the release file.

It is a rather strange sight that index items use SiteOnly which strips
the Path, while e.g. deb files are downloaded with NoUserPassword which
does not. Important to note here is that for the file transport Path is
pretty important as there is no Host which would be displayed by Site,
which always resulted in "interesting" unspecific errors for "file:".
Adding a 'middle' ground between the two which does show the Path but
potentially modifies it (it strips a pending / at the end if existing)
solves this "file:" issue, syncs the output and in the end helps to
identify which file is meant exactly in progress output and co as a
single site can have multiple repositories in different paths.

While it is mostly busywork to rewrite all instances it actually fixes
bugs as the data storage used by the new method is std::string rather
than a char*, the later mostly created by c_str() from a std::string
which the caller has to ensure keeps in scope – something apt-ftparchive
actually didn't ensure and relied on copy-on-write behavior instead
which c++11 forbids and hence the new default gcc abi doesn't use it.

We use test{success,failure} now all over the place in the framework, so
its only consequencial to do this in the situations in which we test for
a specific output as well.

Usually they don't provide a lot in terms of what they test, but they
help in covering many lines from strictly anecdotal commands (stats,
moo) and error messages, so that stuff which really needs to be tested,
but isn't is better visible in coverage reports.

Hide the Hashes,Filename,Multi-Arch,Architecture by default from
"apt show". The information is still available via apt-cache show.
Also improve the output of the Size-
|
|
|
|
|
|
The size/installed-size is displayed via SizeToStr() and Size
is rewriten to "Download-Size" to make clear what size is refered
to here.
