Detect function multiversioning and sse4.2/crc32, enables i386

2019-02-04T14:21:32Z

This fixes the build on kfreebsd-amd64, and due to the detection of sse4.2, should also enable the sse4.2 on i386.

hash32: Tighten to multiversion to x86-64 ELF and use uint32_t

cache hash: Use sse4.2 CRC32c on x86-64 where available

2018-12-26T20:22:37Z

This is more than twice as fast as adler32, but could be made another 50% faster by calculating crcs for 8 byte blocks in "parallel" (without data dependency) and then combining them. But that's complicated code. Reference measurements for hashing the cache 100 times: adler32=2.46s xxhash64=0.64 xxhash32=1.12 crc32c(this)=1.10 crc32c(opt)=0.44s

Fix typo reported by codespell in code comments

No user visible change expect for some years old changelog entries, so we don't really need to add a new one for this… Reported-By: codespell Gbp-Dch: Ignore

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.
