This option is enabled via the APT::FTPArchive::DoByHash switch.
It will also honor the option APT::FTPArchive::By-Hash-Keep that
controls how many previous generation of by-hash files should be
kept (defaults to 3).
Merged from https://github.com/mvo5/apt/tree/feature/apt-ftparchive-by-hash

This is nicer

C++11 adds the 'override' specifier to mark that a method is overriding
a base class method and error out if not. We hide it in the APT_OVERRIDE
macro to ensure that we keep compiling in pre-c++11 standards.

Various small leaks here and there. Nothing particularily big, but still
good to fix. Found by the sanitizers while running our testcases.

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.

This rename with value is ordered by the 'old' name 'Source', but should
be ordered by the new name… by splitting the operation in a delete and a
new field we can easily fix this problem locally for now.

Methods get told which hashes are expected by the acquire system, which
means we can use this list to restrict what we calculate in the methods
as any extra we are calculating is wasted effort as we can't compare it
with anything anyway.
Adding support for a new hash algorithm is therefore 'free' now and if a
algorithm is no longer provided in a repository for a file, we
automatically stop calculating it.
In practice this results in a speed-up in Debian as we don't have SHA512
here (so far), so we practically stop calculating it.

Working with strings c-style is complicated and error-prune,
so by converting to c++ style we gain some simplicity and
avoid buffer overflows by later extensions.

As part of the “reproducible builds” effort [1], we have noticed that
apt could not be built reproducibly.
One issue is that it uses the __DATE__ and __TIME__ macros of the C
preprocessor to display the time of build in the online help. We believe
this information not to be really useful to users as they can always
look at the package data and metadata to figure it out.
The attached patch simply removes this information. All
non-documentation packages can then be built reproducibly with our
current experimental framework.
[David: changed the string slightly to be untranslateable as well]

Your mileage may vary, but don't worry: There is more than one way to
do it, but our one size fits all is not a bigger hammer, but an entire
roundhouse kick! So brace yourself for the tl;dr: The limit is gone.*
Beware: This fixes also the problem that a double newline is
unconditionally added 'later' which is an overcommitment in case
the dsc filesize is limit-2 <= x <= limit.
* limited to numbers fitting into an unsigned long long.

By convention, if I run a tool with --help or --version I expect it to
exit successfully with the usage, while if I do call it wrong (like
without any parameters) I expect the usage message shown with a non-zero
exit.

It is a very simple hashstring, which is why it isn't contributing to
the usability of a list of them, but it is also trivial to check and
calculate, so it doesn't hurt checking it either as it can combined even
with the simplest other hashes greatly complicate attacks on them as you
suddenly need a same-size hash collision, which is usually a lot harder
to achieve.

refactor a bit, extract code out of Generate() into
DoGenerate{PackagesAndSources,Contents}, add new
APT::FTPArchive::ContentsOnly option to allow skipping the generation
of Package/Source files (if they are generated e.g. by some db outside
of apt-ftparchives control)

ContentsExtract::~ContentsExtract() needs to use free() because
Data got allocated via realloc()
Reported-By: clang -fsanitize=address -fno-omit-frame-pointer

Now that libapts acquire system happily passes around hashes and can be
made to support new ones without an ABI break in the future, we can
free ftparchive from all the deprecation warnings the last commit
introduced for it.
The goal here isn't to preserve ABI as we have none to keep here, but to
help avoiding introduction problems of 'new' hashes later as bugs creep
into the copy&paste parts, so short/less of them is good.
|
|
Arrays with predefined lengths are very fragile as they are
likely forgotten in future changes and the size in this case
is dynamic making it even more dangerous.

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

cppcheck complains about the obsolete utime as it was removed in
POSIX1.2008 and recommends usage of utimensat/futimens instead
as those are in POSIX and so commit 9ce3cfc9 switched to them.
It is just that they aren't as portable as the standard suggests:
At least our kFreeBSD and Hurd ports stumble over it at runtime.
So to make both, the ports and cppcheck happy, we use utimes instead.
Closes: 738567

Copy from the bug description:
After we upgraded the Ubuntu master archive from lucid to precise, we
noticed that Translation-en.bz2 was being written with mode 0600 rather
than 0644, which broke our mirroring. This is no longer reproducible as
such in unstable because apt now links against libbz2, but it's still
reproducible with xz; it happens because multicompress fchmods one end
of the compression pipe in this case rather than the target file.
[Original testcase slightly modified to comply with house-style]
Closes: 737130

The most "visible" change is from utime to utimensat/futimens
as the first one isn't part of POSIX anymore.

skipping clearsigning metadata in dsc files

- handle the APT::FTPArchive::Packages::SHA512 option correctly instead
of overriding SHA256, thanks Christian Marillat! (Closes: #680252)
