change got_pack_parse_offset_delta tslen argument to size_t
The tslen argument is always in the (1..9) range so `int' is technically fine (even int8_t would be!) but all the callers are passing a size_t, so change the type accordingly. ok stsp@
move declaration of got_privsep_child out of got_lib_privsep.h
This declaration is the only reason why got_lib_privsep.h must be included in order to use got_lib_repository.h. Moving this declaration will allow for cleaning up unnecessary includes of got_lib_privsep.h.
open temporary files needed for delta application in got_repo_open()
This prepares for callers of got_repo_open() that cannot afford to open files in /tmp, such as gotwebd. In a follow-up change, we could ask such callers to pass in the required amount of open temporary files. One consequence is that got_repo_open() now requires the "cpath" pledge promise. Add the "cpath" promise to affected callers and remove it once the repository has been opened. ok tracey
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@
reuse existing deltas when creating pack files
tested by thomas, naddy, and myself
avoid the creation of new temporary files whenever a packed object is read
This speeds up the creation of pack files by about 30%.
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@
expose got_pack_parse_ref_delta() for library-internal use
This will be needed by a future 'gotadmin listpack' command.
expose got_packidx_get_object_offset() for library-internal use
This will be needed by a future 'gotadmin listpack' command.
add fd field to got_repository, modify got_packidx_open to use fds
These changes are intended to make got more compatible with FreeBSD's Capsicum. ok stsp
