This uses triehash. 2016-11-22T21:56:46Z Julian Andres Klode jak@debian.org 2016-09-27T14:49:25Z urn:sha1:45ecab4458c4015b7635042064165c229e099c28 This allows us to add a perfect hash function to the tag file without having to reimplement the methods a second time. 2016-11-22T21:47:35Z Julian Andres Klode jak@debian.org 2016-09-27T13:24:24Z urn:sha1:3e633069c9c187dc51c12e59a7ddba4b68a76c4f Move the use of the AlphaHash to a new second hash table in preparation for the arrival of the new perfect hash function. With the new perfect hash function hashing most of the keys for us, having 128 slots for a fallback hash function seems enough and prevents us from wasting space. 2016-01-07T18:59:08Z Julian Andres Klode jak@debian.org 2016-01-07T18:16:23Z urn:sha1:eff0c22e59e65b6b63e854ff41eb091278e05714 This improves performance of the cache generation on my ARM platform (4x Cortex A15) by about 10% to 20% from 2.35-2.50 to 2.1 seconds. 2016-01-02T15:20:01Z David Kalnischkies david@kalnischkies.de 2016-01-02T12:27:02Z urn:sha1:f6459e646f6fa45c34d1f13f37173ea4b92ffd5f apt_preferences and deb822-style sources used the specialized class pkgUserTagSection to deal with comments before/after a given stanza, but it couldn't deal with comments in the stanza at all. codesearch suggests that nobody else does and a vastely superior way of working with potentially commented files is implemented now, so we can officially discourage the use of the old incomplete hack class. 2016-01-02T15:19:40Z David Kalnischkies david@kalnischkies.de 2016-01-02T11:25:29Z urn:sha1:55153bf94ff28a23318e79aa48242244c4d82b3c APT usually deals with perfectly formatted files generated automatically be other programs – and as it has to parse multiple MBs of such files it tries to be fast rather than forgiving. This was always a problem if we reused this parser for files with a deb822 syntax which are mostly written by hand however, like apt_preferences or the deb822-style sources as these can include stray newlines and more importantly comments all over the place. As a stopgap we had pkgUserTagSection which deals at least with comments before and after a given stanza, but comments in between weren't really supported and now that we support parsing debian/control for e.g. build-dep we face the full comment problem e.g. with comments inbetween multi-line fields (like Build-Depends). We can't easily deal with this on the pkgTagSection level as the interface gives access to 'raw' char-pointers for performance reasons so we would need to optionally add a buffer here on which we could remove comments to hand out pointers into this buffer instead. The interface is quite large already and supports writing stanzas as well, which does not support comments at all either. So while in future it might make sense to have a parser setup which deals with and keeps comments in this commit we opt for the simpler solution for now: We officially declare that pkgTagSection does not support comments and instead expect the caller to deal with them, which in our case is pkgTagFile: pkgTagFile is extended with an additional mode which can deal with comments by dropping them from the buffer which will later form the input of pkgTagSection. The actual implementation is slightly more complex than this sentence suggests at first on one hand to have good performance and on the other to allow jumping directly to stanzas with offsets collected in a previous run (like our cache generation does it for example). 2015-11-27T14:40:47Z David Kalnischkies david@kalnischkies.de 2015-11-27T14:40:47Z urn:sha1:5dd00edbcf702cac1ea22392796c65881a8ef6f9 Git-Dch: Ignore 2015-09-11T19:54:22Z Julian Andres Klode jak@debian.org 2015-09-11T19:54:22Z urn:sha1:f2adfc081dcadf57088d51479b9d5f012775334a 2015-08-10T15:27:58Z David Kalnischkies david@kalnischkies.de 2015-07-15T12:36:16Z urn:sha1:dfe66c72ffc010e019e96b35154e1ad4ab506a6e We store very few flags in the cache, so keeping storage space for 8 is enough for all of them and still leaves a few unused bits remaining for future extensions without wasting bytes for nothing.
