Deprectate buggy/incorrect Rls/PkgFile::IsOk methods

2018-05-11T15:58:46Z

With the advent of compressed files and especially with in-memory post-processed files the simple assumptions made in IsOk are no longer true. Worse, they are at best duplicates of checks performed by the cache generation (and validation) earlier and isn't used in too many places. It is hence best to simply get right of these calls instead of trying to fix them.

Bump cache major version to allow different 1.5 and 1.6 updates

2018-03-19T13:56:31Z

Shipping 1.6 with major 12 would not allow us to update 1.5.y in a different way than 1.6.y if we have to without resorting to minor version hacks. Let's just bump the major instead.

Reformat and sort all includes with clang-format

2017-07-12T11:57:51Z

This makes it easier to see which headers includes what. The changes were done by running git grep -l '#\s*include' \ | grep -E '.(cc|h)$' \ | xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/' To modify all include lines by adding a space, and then running ./git-clang-format.sh.

pkgcache: Bump major version to 12

2017-06-26T16:57:30Z

We need to be able to update 1.4.y in different ways than later apt versions, and thus need to bump the major version so there is no collision in the minor version at some point.

fix various typos reported by spellintian

Most of them in (old) code comments. The two instances of user visible string changes the po files of the manpages are fixed up as well. Gbp-Dch: Ignore Reported-By: spellintian

Compare size before data when ordering cache bucket entries

2016-11-22T21:58:19Z

This has the effect of significantly reducing actual string comparisons, and should improve the performance of FindGrp a bit, although it's hardly measureable (callgrind says it uses 10% instructions less now).

Introduce tolower_ascii_unsafe() and use it for hashing

2016-11-22T21:58:18Z

This one has some obvious collisions for non-alphabetical characters, like some control characters also hashing to numbers, but we don't really have those, and these are hash functions which are not collision free to begin with.

Bump the cache major version for non-backportable changes

2016-11-22T21:58:18Z

We already have two stable series with major version 10, and the next commits will introduce non-backportable performance changes that affect the cache algorithms, so we need to bump the major version now to prevent future problems.

VersionHash: Do not skip too long dependency lines

2016-09-18T12:17:17Z

If the dependency line does not contain spaces in the repository but does in the dpkg status file (because dpkg normalized the dependency list), the dpkg line might be longer than the line in the repository. If it now happens to be longer than 1024 characters, it would be skipped, causing the hashes to be out of date. Note that we have to bump the minor cache version again as this changes the format slightly, and we might get mismatches with an older src cache otherwise. Fixes Debian/apt#23
