In most cases apt was already skipping the (re)setting of packages as
to be removed/purged if dpkg had told us that it already did, but we
haven't dealt with it in the most obvious of the cases: Selections set
for packages we touched in this operation which either restores
selections even dpkg would have overridden or e.g. tries to restore a
purge selection for a package which was just purged – does not happen
with apt itself as it isn't using selections in this way, but higher
frontends like aptitude do.
The result in the later case is a warning printed by dpkg that we try to
set selections for an unknown package, which is harmless per se, but can
be confusing for users and we really shouldn't cause warnings in dpkg if
we can help it.

The bugreport shows a segfault caused by the code not doing the correct
magical dance to remove an item from inside a queue in all cases. We
could try hard to fix this, but it is actually better and also easier to
perform these checks (which cause instant failure) earlier so that they
haven't entered queue(s) yet, which in return makes cleanup trivial.
The result is that we actually end up failing "too early" as if we
wouldn't be careful download errors would be logged before that process
was even started. Not a problem for the acquire system, but likely to
confuse users and programs alike if they see the download process
producing errors before apt was technically allowed to do an acquire
(it didn't, so no violation, but it looks like it to the untrained eye).

Previously, we would have generated all the translations, but not
turn them on in the code. Instead, move the Translation crap into
po/ and disable po/ alltogether if USE_NLS if OFF.

Commit 7ec343309b7bc6001b465c870609b3c570026149 got us most of the way,
but the last mile was botched by having the pending calls in the wrong
order as this way we potentially 'force' dpkg to remove/purge a package
it doesn't want to as another package still depends on it and the
replacement isn't fully installed yet.
So what we do now is a configure before remove and purge (all with
--no-triggers) and finishing off with another configure pending call to
take care of the triggers.
Note that in the bugreport example our current planner is forcing dpkg
to remove the package earlier via --force-depends which we could do for
the pending calls as well and could be used as a workaround, but we want
to do less forcing eventually.

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.

This workaround is a bit more ugly, but does not use a

Manually clean up the apt.maintscript, it moved stuff from

The README.source is not usable anymore, and the Build-Conflicts

debhelper 10 is much nicer with the installation part from
a dirty tree, so you can just fix some stuff breaking the
install step and then continue building with debuild -b -nc
until you have fixed all your stuff.
It also has some other advantages, of course, like some
bug fixes in shell escaping for maintscript, or systemd
helper changes.

This gets rid of the special casing of etc/apt, various
example file installations handled by the upstream build
system, and of course the directory creation for all dirs
created by the upstream build system.
|
|
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...

Hardcoding gpgv1 and gnupg1 breaks Ubuntu, because on Ubuntu,
these packages do not exist yet. Instead allow gnupg (<< 2)
for gnupg1 and gnupg2 for gnupg (>= 2), so we cover all
potential combinations.
|
|
Our previous hack did not really support or groups and other
more advanced dependency types. This hack basically removes
build profiles, and the @-type depends for tests, and otherwise
converts the deps to a package which is then installed via
gdebi.

Instead of erroring out when receiving a SIGINT, let the
child deal with it - we'll error out anyway if the child
exits with an error or due to the signal. Also ignore
SIGQUIT, as system() ignores it.
This basically fixes Bug #832593, but: we are running
the hooks via sh -c. Some shells exit with a signal
error even if the command they are executing catches
the signal and exits successfully. So far, this has
been noticed on dash, which unfortunately, is our
default shell.
Example:
$ cat trap.sh
trap 'echo int' INT; sleep 10; exit 0
$ if dash -c ./trap.sh; then echo OK: $?; else echo FAIL: $?; fi
^Cint
FAIL: 130
$ if mksh -c ./trap.sh; then echo OK: $?; else echo FAIL: $?; fi
^Cint
OK: 0
$ if bash -c ./trap.sh; then echo OK: $?; else echo FAIL: $?; fi
^Cint
OK: 0

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.

On Ubuntu, cmake installs are vendor-specific apt.conf.d
snippet, causing the build to fail.

The implementation of the generic config fallback did the fallback in
the wrong order so that the least specific option wasn't the last value
picked but in fact the first one… doh!
So in the bugreports case http -> https -> http::<hostname> ->
https::<hostname> while it should have been the reverse as before.

We support "./foobar.deb" as a way to install a deb file directly.
Recently .changes files were added. This highlights a problem as you
can't add the changes file without also trying to install all of them.
Now, it could also be handy to add entire Packages/Sources files to
perhaps get a bunch of packages in without installing them all
implicitly.
This commit introduces --with-source which allows to add *.deb, *.changes,
*.dsc, source-dirs, Packages & Sources files (the later can also be
compressed) without also installing them.

Fingerprints tend to be displayed in space-separated octet pairs so be
nice and allow delete to remove a key based on such a string rather than
requiring that the user is deleting all the spaces manually.
|
|
We need to support partial upgrades anyhow, so we have to deal with the
different versions and your tests try to ensure that we do, so we
shouldn't make any explicit higher requirements.

gpg upstream committed "gpgv: Tweak default options for extra
security." applied on the 1.x and 2.x branches:
http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=commit;h=e32c575e0f3704e7563048eea6d26844bdfc494b
This commit includes "[…], but we should validate the key by its self
signature for primary key, and back signature for subkey."
Our testkeys are old and do not really considered best practices in the
last years, so their most recent self-signature is SHA1-only which with
this gpg commit and our testcases defaulting to --weak-digest sha1 are
refused.
So what we do here is just applying some of the recent best practices on
top of our testcase keys.

Seen in cme #833656 if Dir isn't set (yet) we end up later absoluting a
path which was supposed to be absolute already, so if Dir is empty we
assume it to be '/' instead. In practice this is a bug in the software
using libapt, but for maxium compatibility lets explicitly set the
default value here to be safe.

In af81ab9030229b4ce6cbe28f0f0831d4896fda01 by-hash got implemented as a
special compression type for our usual index files like Packages.
Missing in this scheme was the special .diff/Index index file containing
the info about individual patches for this index file. Deriving from the
index file class directly we inherent the compression handling
infrastructure and in this way also by-hash nearly for free.
Closes: #824926
|
|
The URI we later want to modify to get the file via by-hash was unset in
case a file was only available uncompressed (which is usually not the
case) causing an acquire error.

In af81ab9030229b4ce6cbe28f0f0831d4896fda01 we implement by-hash as a
special compression type, which breaks this filesize setting as the code
is looking for a foobar.by-hash file then. Dealing this slightly gets
us the intended value. Note that this has no direct effect as this value
will be set in other ways, too, and could only effect progress reporting.

If 9b8034a9fd40b4d05075fda719e61f6eb4c45678 serves the Release files
from a partial mirror we will end up getting 404 for some of the
indexes. Instead of giving up, we will instead ignore our same
redirection mirror constrain and ask the redirection service as a
potential hashsum mismatch is better than keeping the certain 404 error.
|
|
Now that we have the redirections loopchecker centrally in our items we
can use it also to prevent internal redirections to loop caused by
bugs as in a few instances we get into the business of rewriting the URI
we will query by ourself as we predict we would see such a redirect
anyway. Our code has no bugs of course, hence no practical difference. ;)

The failure handling frequently changes URI & Description of the failed
item to try a slightly different combination which might work, but the
logging of the failure happens only afterwards as the same failure
handling decides if this is a critical error or not so we need a backup
here instead of potentially new content.
A purely cosmetic issue, but can still be confusing for humans.

If a server closes a connection after sending us a file that tends to
mean that its a type of server who always closes the connection – it is
therefore relatively pointless to try pipelining with it even if it
isn't a problem by itself: apt is just restarting the pipeline each
time after it got served one file and the connection is closed.
The problem starts if one or more proxies are between the server and apt
and they disagree about how the connection should be as in the
bugreporters case where the responses apt gets contain both Keep-Alive
and Proxy-Connection headers (which apt both ignores) indicating a
proxy is trying to keep a connection open while the response also
contains "Connection: close" indicating the opposite which apt
understands and respects as it is required to do.
We avoid stepping into this abyss by not performing pipelining anymore
if we got a respond with the indication to close connection if the
response was otherwise a success – error messages are sent by some
servers via this method as their pages tend to be created dynamically
and hence their size isn't known a priori to them.
Closes: #832113

If the server told us in a previous request that it isn't supporting
Ranges with bytes via an Accept-Ranges header missing bytes, we don't
try to formulate requests using Ranges.
|
|
We keep various information bits about the server around, some only
effecting the currently handled file (like sizes) while others
should be persistent (like pipeline detections). http used to reset all
file-related manually, which is a bit silly if we already have a Reset()
method – which does reset all through –, so extending it with a
parameter for reuse and calling it from https too (as this was
previously resetting by just creating a new state struct – it uses no
value of the persistent state-keeping yet as it supports no pipelining).

This also fixes Debian/apt#20, but is slightly more complete. I

It seems completely pointless from a server-POV to sent empty header
fields, so most of them don't do it (simply proven by this limitation
existing since day one) – but it is technically allowed by the RFC as
the surounding whitespaces are optional and Github seems to like sending
"X-Geo-Block-List:\r\n" since recently (bug reports in other http
clients indicate July) at least sometimes as the reporter claims to have
seen it on https only even through it can happen with both.

Since its existence in 2010 DirectoryExists was always marked with this
attribute, but for no real reason. Arguably a check for the existence of
the file is not modifying global state, so theoretically this shouldn't
be a problem. It is wrong from a logical point of view through as
between two calls the directory could be created so the promise we made
to the compiler that it could remove the second call would be wrong, so
API wise it is wrong.
It's a bit mysterious that this is only observeable on ppc64el and can be
fixed by reordering code ever so slightly, but in the end its more our
fault for adding this attribute than the compilers fault for doing
something silly based on the attribute.

We use clock() as a very cheap way of getting a "random" value, but the
manpage warns that this could return -1, so we should be dealing with
this. Additionally, e.g. on hurd-i386 the value increases only slowly –
to slow for our fast running tests for randomness hence producing the
same range in both samples, so we introduce a simple busy-wait loop (as
clock is counting processor time used by the program) in the test which
delays the second sample just enough making our randomness a bit more
predictable.
