batch up tree entries in imsg instead of sending one imsg per tree entry
This speeds up loading of trees significantly. ok op@
parse tree entries into an array instead of a pathlist
Avoids some extra malloc/free in a performance-critical path. ok op@
rework logic in got_privsep_recv_tree() to avoid an ugly 'goto'
no functional change
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@
factorize imsg_clear calls after imsg_flush failures
imsg_clear frees and closes resources allocated as part of enqueueing imsgs so it's a no-op after reads. discussed with and ok stsp@
reuse existing deltas when creating pack files
tested by thomas, naddy, and myself
ignore the return value of closefrom(2); patch by Anna a.k.a. CyberTailor
millert@ suggests that this check is not needed, and that ideally we should be using close-on-exec instead. I will look into this, but in the meantime this change will help -portable: https://bugs.gentoo.org/828003
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.
provide separate send {} and fetch {} configuration blocks in got.conf
Feature requested by naddy. ok naddy, who also suggested some tweaks that will arrive shortly
add 'got send' command for sending changes to remote repositories
Known to work against git-daemon and github Git server implementations. Tests by abieber, naddy, jrick, and myself. Man page additions reviewed by Lucas.
don't scan pack index offsets for large values if pack file is < 2GB
This saves an iteration over the entire h->offsets array when opening a pack index which should not contain large offsets in the first place. ok millert@
switch from SIMPLEQ to equivalent STAILQ macros
The singly-linked tail queue macros were added to OpenBSD 6.9 and are more widely available on other systems. ok stsp
raw object size should not include the length of the object's header
This way, the size of a raw object is the same regardless of whether the object was found in a loose object file or in a pack file.
