add a test suite for gotd(8); check basic clone and send functionality

avoid incomplete writes of buffered pack file chunks in gotsh

avoid looping over SHA1Update() in got-fetch-pack; suggested by millert@

got-fetch-pack: fix wrong memmove length leading to dubious checksum failures ok millert tracey

portable: compat/sockaddr-linux: add licence header Add the standard header to this file to indicate its licence.

fix typo which caused a double-free in gotd repo_write_shutdown()

gotctl: simplify socket_path handling ok stsp@

remove umask TODO

respect umask when creating or changing files and directories This behaviour is already documented in got-worktree(5) but wasn't actually implemented. ok stsp@

man page fixes suggested by Josiah Frentsos

add gotctl(8); initially supported commands are 'info' and 'stop' This will be used by an upcoming regress test suite for gotd(8). ok tracey

fix syntax error in gotsh.1 sshd_config example

remove sendfd pledge promise from gotd repo_read process Have the parent process send one end of the pipe directly to gotsh(1), such that repo_write can run without "sendfd". Combining "sendfd" and "recvfd" in the same process is frowned upon. ok tracey

change add_delta to take an off_t instead of size_t. add_delta already calls got_delta_open casting the size_t to off_t, and all the add_delta callers pass an off_t anyway; fixes an implicit off_t truncation. ok stsp@

stop installing git-{receive,upload}-pack symlinks to gotsh in ~/bin Having those links in the user's PATH can make our send/fetch regression tests fail. We do want to talk to git-daemon during those tests, and these symlinks can get in the way of that.

convert got_pack' filesize to off_t; ok stsp@

plug a memory leak on error in got_gotconfig_read() ok op@

add missing check for errors from got_gotconfig_read() in open_worktree()

make got.conf(5) warn about remotes configured in locally-shared repositories

sort getopt() option lists and switch statements; patch by Josiah Frentsos

fix off_t type mismatch in gotd see e082ed67; ok stsp@

check size before calling mmap(2) It's only a preparatory step, as checking whether a size_t is less than SIZE_MAX is moot. In a follow-up commit, however, the `filesize' field of the struct got_pack will become off_t and these checks will kick in. This also makes consistent how we guard mmap(2) against empty files. ok and improvements stsp@

add bounds check when reading a delta offset from a packed object ok stsp@

add missing `goto done;' on error path; ok stsp@

fix spelling of "FastCGI"; patch by Josiah Frentsos; ok op@
