zstd is a compression algorithm developed by facebook. At level 19,
it is about 6% worse in size than xz -6, but decompression is multiple
times faster, saving about 40% install time, especially with eatmydata
on cloud instances.

We accidentally did not translate the entity file, but should
have. This makes apt.ent translatable again. This generates the
target multiple times, but surprisingly, that works just fine, so
let's just keep it that way, as it's clean code otherwise.

This fixes a regression introduced in
commit 43b9eb5bac15666fdc0346aca7031fab0fa5e064
CMake: methods: Cleanup link libraries, use OBJECT libraries
Gbp-Dch: ignore
|
|
Use OBJECT libraries for http and connect stuff, and move the
seccomp link expression into a global link_libraries() call.
This also fixes a bug where only the http target pulled in
the gnutls header arguments despite gnutls being used in
connect.cc, and thus by mirror and ftp as well.
Adjust translation support to ignore TARGET_OBJECTS sources
and add the OBJECT libraries to the translated files.
|
|
This reduces the number of syscalls to about 140 from about
350 or so, significantly reducing security risks.
Also change prepare-release to ignore the architecture lists
in the build dependencies when generating the build-depends
package for travis.
We might want to clean up things a bit more and/or move it
somewhere else.

We previously dlopen()ed it, but it seems painful to do that
without any real gain, except for possibly not having libudev
in the address space and not having code #ifdefed for Linux.
The latter means that we are a bit more likely to break stuff
for non-Linux systems now if we play with udev, but at least
we don't end up with it silently breaking because of a libudev
ABI break.
The existing function pointers in the struct were renamed and
kept for compat purposes.
Fixes Debian/apt#48
Also adjust prepare-release to strip [linux-any] from build-depends
for travis.

We have support for an netrc-like auth.conf file since 0.7.25 (closing
518473), but it was never documented in apt that it even exists and
netrc seems to have fallen out of usage as a manpage for it no longer
exists making the feature even more arcane.
On top of that the code was a bit of a mess (as it is written in c-style)
and as a result the matching of machine tokens to URIs also a bit
strange by checking for less specific matches (= without path) first.
We now do a single pass over the stanzas.
In practice early adopters of the undocumented implementation will not
really notice the differences and the 'new' behaviour is simpler to
document and more usual for an apt user.
Closes: #811181

This makes the code easier to read.

Most of them in (old) code comments. The two instances of user visible
string changes the po files of the manpages are fixed up as well.

Our implementation of wildcards was rudimentary. It worked for some
common ones, but it was also broken: For example, armel matched any-armel,
but should match any-arm.
With this commit, we load the correct tables from dpkg. Supported are
both triplets and quadruplet tables (the latter introduced in dpkg 1.18.11).
There are some odd things we have to deal with in the cache filter for
historical and API reasons:
* The character "*" must be accepted as an alternative to any - in fact
it may appear anywhere in the wildcard as we also allow fnmatch() style
wildcard matching on the commandline.
* The code might get passed an arch with a minus at the end, for example
the cmdline "install apt:any-arm-" will first try to check if any-arm-
is a valid architecture. We deal with this by rejecting any wildcard
ending in a minus.
* Triplets are actually implemented by extending them to faux quadruplets
- by prepending a "base" component for the architecture tuple, and "any"
if there is a wildcard component.
Once we have constructed a wildcard, it is transformed into an fnmatch()
expression for historical reasons. In the future, we should really get a
tuple class and implement matching in a better, more explicit way.
This does for now though - it passes all the test cases and accepts all
things it should accept.
Closes: #748936

FreeBSD has two iconv systems: It ships an iconv.h itself,
and symbols for that in the libc. But there's also the port
of GNU libiconv, which unfortunately for us, Doxygen depends
on.
This changes things to prefer a separate libiconv library
over the system one; that is, the port on FreeBSD.

This is needed on BSD where root's default group is wheel, not
root.

This allows other vendors to use different paths, or to build
your own APT in /opt for testing. Note that this uses + 1 in
some places, as the paths we receive are absolute, but we need
to strip of the initial /.
|
|
The BSD systems still ship their own db.h with a historical
BSD implementation, which is preferred by CMake, as it searches
its default path first. We thus have to disable the DEFAULT_PATH
for the search, unfortunately. We also need to pass the correct
include directory to the target.
Furthermore, on FreeBSD the library is called db-<VERSION>, so
let's add db-5 to the list of allowed names.

Distributions seem to install this stuff all over the place, so
let's add a common list of paths we know about.

This module should cover all sorts of large file supports, as long
as they either support the getconf LFS_CFLAGS command; or the
_FILE_OFFSET_BITS=64 or _LARGE_FILES macros.

This fixes some actual bugs for PROJECT and BZIP2_INCLUDE_DIR.

This can lead to an inconsistent state otherwise, with the
output being updated and the byproduct not; for example,
when the build was manually interrupted.
|
|
These directories are essential for apt to work, so we should
install them in the upstream build system and not just in the
debian packaging...

When updating our .po files, pass --previous to msgmerge
to make it easier for translators to translate fuzzy
strings.
Thanks: Guillem Jover for the suggestion.
|
|
If only the line numbers changed in a file without any of the
translatable strings changing, the .po and .mo files were
rebuilt, making building simple code changes somewhat annoying.
We can work around this by passing --add-location=file to msgcomm
when we are creating the temporary .pot file used for building
the .mo files.

I don't know what happened back in 2009 when I wrote this,
but it seems I used the wrong option. These files should
not have any variable substitution done to them.

This can now build all documentation. It should also be fairly
reusable for other projects, as long as they follow the same
naming scheme for the po4a output files and set the PACKAGE_*
variables used here.
We could have done all translations in a single call to po4a
like the makefile based buildsystem does. While that would
have made the output slightly nicer, this solution offers a
huge performance gain because it can translate the documents
in parallel, which also means that the xsltproc stage does not
have to wait for all translations to be done first.
You might think that the add_custom_command() should list the
actual output files as BYPRODUCTS. This is not true however:
Because the files are not always generated, Ninja will think
missing byproducts mean that the target is out of date - which
is not what we want.
Finally, also add the missing doxygen support. Note that the
packaging script cleans up some md5 and map files created by
doxygen, otherwise it is fairly boring.

This abstracts the joining of paths a bit better than having
basically the same code twice in the Translations module.

This was dropped in autotools as I found no use of the HAVE_PTSNAME_R
macro. Turns out it was typoed as HAVE_PTS_NAME_R. Fix the #ifdef and
add checks to CMake for it.

This seems to be needed for the hebrew translations.

Use the witness/byproducts approach to build the translations. A
byproduct of a command is like an output, but may be older than the
input.
Here, we generate a normal template with headers in the normal way
as a witness (and for Launchpad translations), but we also generate
a .pot-tmp0 template file without a header that gets copied to a
.pot-tmp byproduct only if it changed. This way, the .pot-tmp is
only updated if an actual string translation changed. We also
create a custom target for the .pot file that we'll depend on
later in the overall target creating the mo files to ensure that
the template is build before we try to build mo files.
Then we make the msgmerge depend on the .pot-tmp instead of the .pot
file, which means that msgmerge and msgfmt only get re-run if a string
change occured.

This is really useful stuff to have.

Merge all the per-domain templates into one template file using
msgcomm, stripping any line numbers in the input files, and sorting
the output per file.
This should create reasonably stable .pot and .po files that do not
change just because files move around. It should also be resilient
against some line changes, as long as one translated line is not
moved before/after another translated line.

Rework the arguments to apt_add_translation_domain so a user
can specify TARGETS and SCRIPTS, the latter being Shell scripts.
For each language (TARGETS being C++, SCRIPTS being Shell), a separate
template is generated via xgettext. Those templates are then merged
together by using msgcomm. In case there are no Shell scripts in
the translation domain, msgcomm will receive /dev/null instead of
a shell translation template.
This also reintroduces line numbers, as msgcomm would otherwise
re-order the merged files not only by filename, but also by message
string. It's unclear why it does that, it could just leave strings
within a file alone.
In contrast to the old build system, we use xgettext for shell scripts
instead of bash --dump-strings, as it's just easier to use the same
tool for everything. We also create valid headers.

This makes debugging things easier.

This gets rid of the line numbers, adds the plural keyword,
and makes msgfmt print statistics, so we know how well translated
we are.

I wondered why the template was not rebuilt after I changed a file,
now I have the answer.

This is needed in a lot of places. Also adjust config.h.in to use
it instead of the bare email address.

First of all, instead of creating the files at configure time,
generate the files using normal target. This has the huge advantage
that they are rebuilt if their input changes. While we are at it,
also add dependencies on the vendor entity files.
This also fixes the path to the vendor script, which was given
relatively before, which obviously won't work when running from
inside a deeper subdirectory.
To speed things up, pass the --vendor option to getinfo, so we
do not have to find out the current vendor in getinfo all over
again.

Build HTML docbook guides (untranslated) and manual pages
(including translations). Also install the examples in the
example subdirectory.
Translation of docbook guides has not been implemented yet,
but should be easy to do. The code also needs some cleanup
to automatically detect the available translations.
|
|
Introduce support for building translation domain-specific
templates, merging them with the translations, and building
a language-specific .mo file.
The invocation of xgettext is done in the project source
directory, not in the current source directory, and all paths
are made relative to the project root, in order to have clean
templates.
This only supports the C++ source code for now, it unfortunately
does not handle the shell scripts of deselect yet.
|
|
Introduce an initial CMake buildsystem. This build system can build
a fully working apt system without translation or documentation.
The FindBerkelyDB module is from kdelibs, with some small adjustements
to also look in db5 directories.
Initial work on this CMake build system started in 2009, and was
resumed in August 2016.
