let callers of got_pack_create() configure rate-limiting of progress reporting Needed by future gotd(8), where progress reports will be sent to a network socket, rather than a local terminal.

do not crash if no delta cache is present while parsing deltas

portable: sort makefile source lines For all key Makefile.am files in use, sort the files so that they're more easily identifiable -- especially when adding/removing source files.

portable: fixup portably-included headers Remove certain headers which are included portably.

portable: fix tests

move privsep code from pack_create.c into new file pack_create_privsep.c Needed by future gotd(8). ok op@

handle unlink(2) errors for mergepath, tmppath, and apath in apply_patch() ok op@

introduce got_path_move_file(); based on code from lib/patch.c ok op@

check for unlink(2) errors and don't try to unlink an already renamed file ok op@

check for unlink(2) errors in got_opentempfd() ok op@

check for unlink(2) errors with the == -1 idiom, rather than != 0 ok op@

move got_opentempfd() call out of got_pack_create() Future gotd(8) needs to run got_pack_create() in a chroot environment, so we can no longer open new temporary files inside got_pack_create(). ok op@

make got_pack_create() write to a file descriptor instead of a stdio FILE The old code required a seekable output file. This conflicts with requirements of future gotd(8), which will write pack file data to network sockets. ok op@

simplify the way 'got patch' opens a tempfile when reading from stdin Also add basic test coverage for reading patches from stdin, while here. ok op@

remove accidentally committed debug assertion

portable: handle sys/tree.h Unfortunately, MacOS doesn't provide sys/tree.h -- so the compat check for this must happen portably.

portable: regress: order lib files For those tests which rely on compilation files, order them alphabetically so it's easier when having to change the makefile stanzas.

portable: check for sys/tree.h more fully When checking for sys/tree.h on non-BSD systems, either it will be in the standard include path (such as on MacOS), or it won't be found, until libbsd is overlayed. In cases where we want to find sys/tree.h via libbsd, perform a AC_CHECK_DECL for a known #define in sys/tree.h -- which will still find sys/tree.h in either location, or uses compat/tree.h in all other cases.

portable: remove sha1.h include This is searched for portably.

move got_gotconfig_read() into new file read_gotconfig_privsep.c

remove unnecessary includes of got_lib_privsep.h

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.

move code for reading Git's config file into new file read_gitconfig_privsep.c The end goal here is to remove the dependency of repository.c on privsep.c during compilation.

move code which forks child processes into a subroutine, reducing copy-pasta

move functions which open objects into new file object_open_privsep.c For the future, this will make it possible to provide alternative implementations of functions now stored in object_open_privsep.c. This will probably be needed by future gotd(8) which runs inside a chroot(2) environment and without the "exec" pledge(2) promise, making it impossible to run libexec helpers on the fly. Details of this design are not yet settled, but moving functions into a separate compilation unit won't hurt in any case.
