2015-04-19calculate only expected hashes in methodsDavid Kalnischkies
Methods get told which hashes are expected by the acquire system, which means we can use this list to restrict what we calculate in the methods as any extra we are calculating is wasted effort as we can't compare it with anything anyway. Adding support for a new hash algorithm is therefore 'free' now and if a algorithm is no longer provided in a repository for a file, we automatically stop calculating it. In practice this results in a speed-up in Debian as we don't have SHA512 here (so far), so we practically stop calculating it.
2014-11-08replace ignore-deprecated #pragma dance with _PragmaDavid Kalnischkies
For compatibility we use/provide and fill quiet some deprecated methods and fields, which subsequently earns us a warning for using them. These warnings therefore have to be disabled for these codeparts and that is what this change does now in a slightly more elegant way. Git-Dch: Ignore
2014-10-24promote filesize to a hashstringDavid Kalnischkies
It is a very simple hashstring, which is why it isn't contributing to the usability of a list of them, but it is also trivial to check and calculate, so it doesn't hurt checking it either as it can combined even with the simplest other hashes greatly complicate attacks on them as you suddenly need a same-size hash collision, which is usually a lot harder to achieve.
2014-09-30support parsing of all hashes for pdiffDavid Kalnischkies
The fileformat of a pdiff index stores currently only SHA1 hashes. With this change, we look for all other hashes we support as well and take what we get, so that we can work after the release of jessie to get right of SHA1 if we want to. Note that the completely patched file is and was checked against the hashes collected from the Release file, so this transition isn't mission critical.
2014-05-09use HashStringList in the acquire systemDavid Kalnischkies
It is not very extensible to have the supported Hashes hardcoded everywhere and especially if it is part of virtual method names. It is also possible that a method does not support the 'best' hash (yet), so we might end up not being able to verify a file even though we have a common subset of supported hashes. And those are just two of the cases in which it is handy to have a more dynamic selection. The downside is that this is a MAJOR API break, but the HashStringList has a string constructor for compatibility, so with a bit of luck the few frontends playing with the acquire system directly are okay.
2014-05-09add a simple container for HashStringsDavid Kalnischkies
APT supports more than just one HashString and even allows to enforce the usage of a specific hash. This class is intended to help with storage and passing around of the HashStrings. Git-Dch: Ignore
2014-04-04Implement CacheDB for source packages in apt-ftparchiveMichael Vogt

2014-03-13cleanup headers and especially #includes everywhereDavid Kalnischkies
Beside being a bit cleaner it hopefully also resolves oddball problems I have with high levels of parallel jobs. Git-Dch: Ignore Reported-By: iwyu (include-what-you-use)
2014-01-16correct some style/performance/warnings from cppcheckDavid Kalnischkies
The most "visible" change is from utime to utimensat/futimens as the first one isn't part of POSIX anymore. Reported-By: cppcheck Git-Dch: Ignore
2013-11-26add check when sources.list changedMichael Vogt
2011-12-17try to avoid direct usage of .Fd() if possible and do read()s and coDavid Kalnischkies
on the FileFd instead
2011-09-19do not pollute namespace in the headers with using (Closes: #500198)David Kalnischkies
2011-09-13Support large files in the complete toolset. Indexes of thisDavid Kalnischkies
size are pretty unlikely for now, but we need it for deb packages which could become bigger than 4GB now (LP: #815895)
2011-09-13reorder includes: add <config.h> if needed and include it at firstDavid Kalnischkies
2011-07-14fix sha512 calculation in Hashes::VerifyFiles()David Kalnischkies

2010-01-31merge r1966..1967 from lp:~donkult/apt/sidMichael Vogt
2009-07-21The 'not dead yet' releaseMichael Vogt
* add hook for MarkInstall and MarkDelete (closes: #470035) * add the various foldmarkers in apt-pkg & cmdline (no code change) * versions with a pin of -1 shouldn't be a candidate (Closes: #355237) * prefer mmap as memory allocator in MMap instead of a static char array which can (at least in theory) grow dynamic * eliminate (hopefully all) segfaults in pkgcachegen.cc and mmap.cc which can arise if cache doesn't fit into the mmap (Closes: #535218) * display warnings instead of errors if the parts dirs doesn't exist * honor the dpkg hold state in new Marker hooks (closes: #64141)
2009-07-16* apt-pkg/contrib/hashes.cc, apt-pkg/contrib/md5.cc:Julian Andres Klode
- Support reading until EOF if Size=0 to match behaviour of SHA1Summation and SHA256Summation
2009-06-30add the various foldmarkers in apt-pkg & cmdline (no code change)David Kalnischkies
2007-07-30* apt-pkg/acquire-item.{cc,h}:Michael Vogt
- rename "hash" into ExpectedHash in pkgAcqFile, pkgAcqIndex - add missing HashSum() call to class pkgAcqIndex - use the data provided by acquire-method (and send via the {SHA256,SHA1,MD5Sum}-Hash tag when comparing the hash, this avoids calculating the hash twice (just like old libapt) * apt-pkg/acquire-method.cc: - send MD5Sum-Hash tag to libapt to be consistant with HashString::SupportedHashes() * apt-pkg/acquire-worker.cc: - check with "Owner->HashSum().HashType()" what hash the frontend is expecting and pass it to pkgAcquireItem::Done() in the new HashString format - add some debugging output * apt-pkg/contrib/hashes.cc: - fix off-by-one error when constructing a HashString from a single input string * apt-pkg/contrib/hashes.h: - add "HashType()" method * apt-pkg/init.h, apt-pkg/makefile, methods/makefile: - break ABI
