netrc: Restrict auth.conf data to https by default
See merge request apt-team/apt!84
|
|
This avoids downgrade attacks where an attacker could inject
Location: http://private.example/
and then (having access to raw data to private.example, for example,
by opening a port there, or sniffing network traffic) read the credentials
for the private repository.

While passing the combi Release and Release.gpg to the gpgv method for
verification the filename of Release is placed where usually Release.gpg
is assumed in the rest of the code. The "usual" cases like passing
verification and failing verification ending in an error are taking care
of this, but the code path dealing with a failed verification, but
ignoring said failure (e.g. due to trusted=yes) was not which results in
the wrong file being removed later on (in case the index happens to be
unmodified since the last update call) leading us into the abyss of
strange failures (fixed in the previous commit) were nothing should have
changed.
This is not a security issue in this form as the repository needs to fail
verification & the user forcing apt to ignore the failure and carry on
anyhow. It does show however how complicated the code and its various
interconnected paths can become.

If we have no old Release file, but old indices we can't compare
hashsums with the new Release file and hence must request the indices
again and have to react to IMS hits if they didn't change.
We used to symlink the old index file to the partial directory, but that
usually meant that we linked an uncompressed file to a compressed file,
which not all uncompressors can deal with transparently resulting in
strange failures.
We could do without the symlink, but that would require changes in the
codepaths dealing with failure as they would rename the file to FAILED.

Skipped tests do not age very well as changes to the infrastructure go
by unnoticied. In this case we are fetching Translation files now
differently meaning only if mentioned in Release file, which broke this
test. As it makes use of LC_ALL and utf8 locales it can't really be
reenabled, but it might be able to serve as an example for others and
hence at least deserves being fixed.
Gbp-Dch: Ignore

Unused variable, std::algorithms instead of raw for-loops.
There should be no observeable difference in behaviour.

This is pure syntactic sugar - ?narrow does not exist in the
abstract syntax.

Fix progress bar width for multibyte charsets
See merge request apt-team/apt!81
|
|
When using locale in which symbols occupy more than 1 byte (for example,
ru_RU.UTF-8), the progress bar width was calculated incorrectly because
std::string::size() returns the number of bytes rather than the number of
actual characters. Use the newly introduced APT::String::DisplayLength()
to calculate the width instead.
|
|
Returns string length, but unlike std::string::size() it honors
multibyte characters. This allows to properly calculate visible
sizes of console messages.

Search in all available description translations
See merge request apt-team/apt!79
|
|
When multiple translations of package descriptions are available,
perform search in all of them. It allows using search patterns in
any of the configured languages.
Previously, only the first available translation was searched. As
the result, patterns in e.g. English never matched packages which
had their descriptions translated into local language.

We recently made info an alias for show, but we did not change the
command-line parser to work around it.

GTest 1.9 uses a variable defined in the parent directory, thus
failing to configure. Configure the project in the parent directory
instead.

Using --force-depends causes dpkg to continue removing packages
a package depends upon even if that package fails to be removed,
because dpkg turns off all sanity checks. So we gotta tell dpkg
to stop immediately if there's an error removing stuff.

This should probably make those functions thread-safe, which
might be useful for some external users.

Commit 1d9e29c9e2a5591b42a99a721b901fc003ed9149 added support
for suffixes to to intervals, but did not adjust the code to
actually support them by replacing -eq with =.

In C++, this warns about not returning in a function not returning
void, which is undefined behavior and causes weird crashes. Make it
an error.

Package patterns
See merge request apt-team/apt!74
|
|
Only disallow ,() and on the start of a word also ~ and ?. Make
sure to include \0 as disallowed.
|
|
|
|
This matches any package that does not have versions.
|
|
The ?exact-name pattern matches the name exactly, there is
no substring matching going on, or any regular expression
or fnmatch magic.
|
|
This matches all packages where at least one of the versions
is marked essential; or well, whenver apt considers a package
essential.
|
|
This matches all packages that have broken dependencies in the
installed version or the version selected for install.
|
|
These two are mutually exclusive states of installed-ness. And
?installed package is fully unpacked and configured; a ?config-files
package only has config files left.
|
|
These match packages that have no version in a repository, or
where an upgrade is available. Notably,
?and(?obsolete,?upgradable) == ?false
because an upgradable package is by definition not obsolete.
|
|
These patterns allow you to identify automatically installed
packages, as well as automatically installed packages that are
no longer reachable from the manually installed ones.
|
|
This implements the basic logic patterns:
?and ?false ?not ?or ?true
and the basic package patterns:
?architecture ?name ?x-name-fnmatch
|
|
This adds a transformation from parse tree into a CacheFilter and
connects it with cachesets and the apt list command.
|
|
This does not describe much yet, as there's not much to talk
about.
|
|
Introduce a parser for patterns that generates a parse tree. The
language understood by the parser is:
pattern = '?'TERM
| '?'TERM '(' pattern (',' pattern)* ','? ')'
| WORD
| QUOTED-WORD
TERM = [0-9a-zA-Z-]
WORD = [0-9a-ZA-Z-.*^$\[\]_\\]
QUOTED_WORD = "..." # you know what I mean
This language is context free, which is a massive simplification
from aptitude's language, where ?foo(bar) could have two different
meanings depending on whether ?foo takes an argument or not.

Fix segfault in pkgAcquire::Enqueue() with Acquire::Queue-Mode=access
See merge request apt-team/apt!73
|
|
Unfortunately for us, apt update with Acquire::Queue-Mode=access
does not always crash on a real system, so run the whole thing
in valgrind.
