2014-05-30without a filename we can't stat pipesDavid Kalnischkies
EDSP code uses pipes opened via an FD as sources and later for those files modification times and filesize are read - but never really used again. The result we get from FileFd is probably wrong, but as we don't use it anyway, we just don't fallback if we have nothing to fallback to Git-Dch: Ignore

2014-04-26fix FileFd::Size bitswap on big-endian architecturesAdam Conrad
gzip only gives us 32bit of size, storing it in a 64bit container and doing a 32bit flip on it has therefore unintended results. So we just go with a exact size container and let the flipping be handled by eglibc provided le32toh removing our #ifdef machinery. Closes: 745866
2014-04-16clear HitEof flag in FileFd::SeekDavid Kalnischkies
fseek and co do this to their eof-flags and it is more logic this way as we will usually seek away from the end (e.g. to re-read the file). The commit also improves the testcase further and adds a test for the binary compressor codepath (as gz, bzip2 and xz are handled by libraries) via the use of 'rev' as a 'compressor'.
2014-04-11deal with umask only if we really need to for mkstempDavid Kalnischkies
As the comment actually says: open() does the umask dance by itself, so we don't need to do it for it. We have to do it after mkstemp in Atomic though, so move it into the if. Also removes the "micro-optimisation" "FilePermissions == 600" as it doesn't trigger at the moment anyway as 600 != 0600.
2014-04-11don't double-count seeks in FileFd::Skip for bzip/xzDavid Kalnischkies
FileFd::Read already deals with the increase of the skipposition so that we as the caller in FileFd::Skip really shouldn't increase it, too.

2014-04-10Rename FileFd::Open() Perms to AccessModeMichael Vogt
Bug lp:#1304657 was caused by confusion around the name Perms. The new name AccessMode should make it clear that its not the literal file permissions but instead the AccessMode passed to open() (i.e. the umask needs to be applied)
2014-04-10Fix insecure file permissions when using FileFd with OpenMode::AtomicMichael Vogt
Commit 7335eebea6dd43581d4650a8818b06383ab89901 introduced a bug that caused FileFd to create insecure permissions when FileFd::Atomic is used. This commit fixes the permissions and adds a test. The bug is most likely caused by the confusing "Perm" parameter that is passed to Open() - its not the file permissions but intead the "mode" part of open/creat.

This debug option will display all scripts that are run by apts RunScripts and RunScriptsWithPkgs helpers.
2014-03-21continue reading in xz even if it outputs nothingDavid Kalnischkies
It can happen that content in our buffer is not enough to produce a meaningful output in which case no output is created by liblzma, but still reports that everything is okay and we should go on. The code assumes it has reached the end through if it encounters a null read, so this commit makes it so that it looks like this read was interrupted just like the lowlevel read() on uncompressed files could. It subsequently fixes the issue with that as well as until now our loop would still break even if we wanted it to continue on. (This bug triggers our usual "Hash sum mismatch" error) Reported-By: Stefan Lippers-Hollmann <s.L-H@gmx.de>
2014-03-15Fix handling of autoclosing for compressed files (Closes: #741685)Julian Andres Klode
AutoClose is both an argument in OpenDescriptor() and an enum. In commit 84baaae93badc2da7c1f4f356456762895cef278 code using the AutoClose parameter was moved to OpenDescriptorInternal(). In that function, AutoClose meant the enum value, so the check was always false.

They tend to be ugly to look at, so hide them. Git-Dch: Ignore
2014-03-13use liblzma-dev to provide xz/lzma supportDavid Kalnischkies
We have xz/lzma support for a while, but only via an external binary provided by xz-utils. Now that the Debian archive provides xz by default and dpkg pre-depends on the library provided by liblzma-dev we can switch now to use this library as well to avoid requiring an external binary. For now the binary is in a prio:required package, but this might change in the future. API wise it is quiet similar to bz2 code expect that it doesn't provide file I/O methods, so we piece this together on our own.

2014-02-14simplify code some more to make reddit happyDavid Kalnischkies
Commit 6008b79adf1d7ea5607fab87a355d664c8725026 should have been guarded by "Git-Dch: Ignore", but it wasn't and I only noticed it with the Close message via deity thinking "hehe, I wonder if someone is gonna notice". Looks like someone did: hats off to reddit user itisOmegakai! Good to know that what I do isn't only monitored by goverments. :) As there is another instance of basically the same code we just factor out the code a bit and reuse, so its even cleaner and not only simpler.

2013-11-30truncating /dev/null to zero is always successfulDavid Kalnischkies
Calling truncate on /dev/null can happen by the download methods if they are instructed to download a file to /dev/null (as testcases are only interested in the status code, but do not support HEAD requests yet) So just ignore truncate calls on the /dev/null file as it is always empty anyway, so truncating to zero isn't a problem.

2013-08-31fix typo (mkostemp->mkstemp)Michael Vogt
2013-08-27use mkstemp instead of mkostemp in FileFd::Open()David Kalnischkies
FileFd currently supports no fileflags which would make sense to provide via mkostemp, so we can just use mkstemp here which is a standard function compared to glib extension mkostemp. O_CREAT (Create) and O_TRUNC (Empty) are implied by O_EXCL, which is the mode mkstemp uses by default. The file description is opened ReadWrite, but that used to be the default for FileFd in the old times and not a problem as the difference is needed by FileFd to decide in which way the compressor pipeline needs to be created (if any). Git-Dch: Ignore
2013-08-27replace usage of potential dangerous mktemp with mkstempAngel Guzman Maeso
Avoid the warning "the use of `mktemp' is dangerous, better use `mkstemp' or `mkdtemp'". It is not strictly necessary to change the usage from a security point of view here, but mktemp is also removed from the standard since POSIX.1-2008. The mkostemp call returns a file descriptor the logic for TemporaryFileName has been changed accordingly to get the same results. The file permissions are corrected by using fchmod() as the default for FileFd is 666 while mkstemp creates files with 600 by default.
