run the search for deltas to reuse in got-read-pack This significantly speeds up the deltification step of packing by avoiding imsg traffic. gotadmin no longer requests individual raw deltas from got-read-pack to check whether it can reuse them. Instead, got-read-pack obtains a list of objects we want to pack, and hands back the list of all deltas in its pack file which can be reused. Messages are now batched such that imsg buffers are filled as much as possible. Another advantage is that deltas we are not going to reuse will no longer be written to the delta cache file, saving disk space. Before this patch, any raw delta candidate was written to the delta cache file by got-read-pack, and the decision whether to reuse the delta happened afterwards in the gotadmin process. Code for reading individual raw deltas is now unused and could be removed at some point. ok op@

store deltas in compressed form while packing, both in memory and cache file This reduces memory and disk space consumption during packing. with tweaks + memleak on error fix from op@ ok op@

inline struct got_object_id in struct got_object_qid Saves us from doing a malloc/free call for every item on the list. ok op@

stop relying on commit cache for good performance of got_object_id_by_path() Instead of internally opening and closing the same commit object over and over again, require callers to pass an open commit object in. Avoids an inherent dependency on the commit object cache for reasonable performance. ok op@

reuse existing deltas when creating pack files tested by thomas, naddy, and myself

map raw object files into memory while packing if possible

avoid the creation of new temporary files whenever a packed object is read This speeds up the creation of pack files by about 30%.

add O_CLOEXEC (close-on-exec) flag to open(2) calls suggested by millert ok thomas_adam

portable: tree/queue header fixes sys/{tree,queue}.h are looked up via configure, and therefore are included via that mechanism.

Revert "cache raw objects in order to speed up gotadmin pack" This reverts commit c565dfd37a157bab9556aceac96ff27d64525fc9.

cache raw objects in order to speed up gotadmin pack

use RB_TREE instead of STAILQ to manage packindex bloom filters; much faster

portable: update to handle bloom, etc Update portable to support changes for bloom, etc.

raw object blocksize and read buffer were unused; remove them

remove unused internal raw object API functions

cache raw objects in order to speed up gotadmin pack

reuse temporary files which were not used by got_object_raw_open()

add missing error checks in got_object_raw_open()

use RB_TREE instead of STAILQ to manage packindex bloom filters; much faster

implement 'got diff -c' for diffing commits with optional filtering by path Need for filtering by path sugggested by kn@ ok naddy@

portable: add FreeBSD support This adds the capability to compile got-portable on FreeBSD.

portable: initial Linux compilation This commit modifies the GoT main branch to be able to compile it under linux.

verify object ID checksums while loose objects are being accessed

make got_packidx_get_packfile_path() usable for callers who only have a path

implement 'gotadmin cleanup'
