parse tree entries into an array instead of a pathlist
Avoids some extra malloc/free in a performance-critical path. ok op@
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@
got patch: allow to strip path components
Move some bits from the libexec helper to the main process so we know if the patch was generated by git or not and finally document the automatic stripping of a/ and b/ prefixes added by git-diff(1). ok stsp@
reuse existing deltas when creating pack files
tested by thomas, naddy, and myself
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@
add a 'reference' directive to remote repositories in got.conf(5)
Make use of this in 'got clone' to persist -R option arguments given on the command line in the cloned repository's got.conf(5) file.
add a 'fetch-all-branches' configuration setting to got.conf(5)
Set fetch-all-branches in the got.conf(5) file created by 'got clone -a' in order to make a future 'got fetch' act like 'got fetch -a' by default.
add got.conf(5) configuration file
