* aptconfiguration: Set default compression level to 6Julian Andres Klode2015-12-281-5/+5
| | | | | | | | | | | | | | | | | | Since commit 7a68effcb904b4424b54a30e448b6f2560cd1078, the xz and lzma compressors read the level of compression they shall use. A default of -9 is too much for them, this will use 674 MB, according to the xz manual page. Level -6 on the other hand only needs 94 MB memory for compression. This causes autopkgtest failures in the test-compressed-indexes test, as not enough memory exists to proceed. Change the other compression levels to 6 as well: The gzip and bzip2 FileFd backends do not read them, and use their code's default level which is 6, so do the same for external methods.

* try xz instead of bz2 first for compressed filesDavid Kalnischkies2015-08-291-9/+9
| | | | | | | | | | | | | | | | | | xz has pretty much won "the compressor war" and e.g. the Debian archive doesn't even distribute bz2 anymore in favor of 'xz' and 'gz', so by changing the default order we have a more realistic --print-uris behavior as it will always show the first compressor. In practice this effects repositories without a Release file (very bad, we don't want to support them anymore anyhow) as xz will be tried before bz2 now [which is probably not available, but so might be bz2…] AND repositories which provide both, bz2 and xz (which isn't too common) in sofar as apt will now download xz instead of bz2. Users with special needs can stick with bz2 as first compressor tried with Acquire::CompressionTypes::Order:: "bz2"; (see man apt.conf) – but users with special needs usually prefer "gz" anyhow, so the realworld change is expected to be very low.
* use c++11 algorithms to avoid strange compiler warningsDavid Kalnischkies2015-08-291-10/+6
| | | | | | | | | | | | | Nobody knows what makes the 'unable to optimize loop' warning to appear in the sourceslist minus-options parsing, especially if we use a foreach loop, but we can replace it with some nice c++11 algorithm+lambda usage, which also helps in making even clearer what happens here. And as this would be a lonely change, lets do it for a few more loops as well where I might or might not have seen the warning at some point in time, too. Git-Dch: Ignore

* Make apt compile with clang++ againMichael Vogt2015-08-141-1/+1
| | | | | This allows us to run the clang static analyzer and to run the testsuite with the clang MemorySanitizer.
* mark private methods as hiddenDavid Kalnischkies2014-09-301-29/+29
| | | | | | | | | | We are the only possible users of private methods, so we are also the only users who can potentially export them via using them in inline methods. The point is: We don't need these symbols exported if we don't do this, so marking them as hidden removes some methods from the API without breaking anything as nobody could have used them. Git-Dch: Ignore
* invalid cache if architecture set doesn't matchDavid Kalnischkies2014-05-101-1/+1
| | | | | | | | | | | | | | The cache heavily depends on the architecture(s) it is build for, especially if you move from single- to multiarch. Adding a new architecture to dpkg therefore has to be detected and must invalidate the cache so that we don't operate on incorrect data. The incorrect data will prevent us from doing otherwise sensible actions (it doesn't allow bad things to happen) and the recovery is simple and automatic in most cases, so this hides pretty well and is also not as serious as it might sound at first. Closes: 745036
* do not create an (additional) empty compressorDavid Kalnischkies2014-04-111-1/+1
| | | | | | | | FileFd code knows how to deal with such a compressor, so it isn't a problem, but it is absolutely not needed as we already have an (matching) identity compressor with '.' earlier in the list. Git-Dch: Ignore
* use liblzma-dev to provide xz/lzma supportDavid Kalnischkies2014-03-131-0/+8
| | | | | | | | | | | | 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.
* cleanup headers and especially #includes everywhereDavid Kalnischkies2014-03-131-2/+7

* support DEB_BUILD_PROFILES and -P for build profilesDavid Kalnischkies2014-03-131-1/+25
| | | | | | | | | | Inspired by the rest of the patch in 661537, but abstract the parsing of various ways of setting the build profiles more so it can potentially be reused and all apt parts have the same behaviour. Especially config options, cmdline options and environment will not be combined as proposed as this isn't APTs usual behaviour and dpkg doesn't do it either, so one overrides the other as it normally does.
* add default and override handling for Cnf::FindVectorDavid Kalnischkies2014-03-131-61/+11
| | | | | | Automatically handle the override of list options via its parent value which can even be a comma-separated list of values. It also adds an easy way of providing a default for the list.

* fix lzma-support detection via xz binaryDavid Kalnischkies2013-10-031-1/+1
| | | | | | Clear() only clears a config option, not removing it and an empty setting still exists. Hence we set the option instead to the xz path so that the later existance check can find a binary for the test
