do not forget to free(cwd) at the end of cmd_rebase() and cmd_histedit()

fix wrong error return in cmd_commit()

We don't care about the length of the read line. Found by llvm's scan-build (dead store). OK stsp

Dot not ignore error from got_object_id_str(). Found by llvm's scan-build (dead store). OK stsp

typo in cat_commit otherwise prints the author instead of the committer

got commit: add flag to specify the author This adds a new flag, `got commit -A', that allows to specify the commit author but retains the "committer" (which is obtained as usual via GOT_AUTHOR, got.conf or git config.) with lots of help from and ok stsp

fix email address parsing we were both too strict and too lose. To avoid breaking got object parser (and to some extent ours too) we need to ensure that there aren't any line feeds, extra < or > and no trailing gibberish. The '@' is not actually required in the email. various tweaks and ok stsp

portable: add back sys/queue.h Now that the handling of including sys/queue.h is better, there's no need to remove those lines from the source. Copy the location of those original sys/queue.h lines from upstream at the same line number, so as to avoid any conflicts in the future.

histedit: make sure mesg is only used after pick or edit It doesn't really make sense to use mesg after a fold or drop, or after another mesg. it currently "works" as intended, but the behaviour is confusing and not useful, better abort the operation as it's probably not what the user intended.

got tag -V is like tag -l with verification, fix option-conflicts accordingly

add signer_id option to got.conf(5) Setting this option will cause 'got tag' to sign all created tags using the SSH key, unless overridden by the -s flag. ok stsp@

move 'got init' command to 'gotadmin init' This functionality is better suited for gotadmin because it is technically a server-side repository operation when we consider the 'got' tool as the client-side tool. I have plans to move 'got import' into gotadmin as well. ok op@

portable: remove sys/queue.h This is included portably.

include system headers required for got_date.h directly, not indirectly

add -V option to 'got tag' usage string, and replace underscore with a hyphen

add option-conflict handling for 'got tag' -s and -V options

add -v option to 'got tag' usage string

got tag -V is like tag -l with verification, fix option-conflicts accordingly

add -V option to 'got tag' usage string, and replace underscore with a hyphen

fix tag signing when the key file does not exist This should fail without creating any tag. Before, ssh-keygen(1) would print an error to stderr, but got would create an unsigned tag. ok op@

rename got.conf(5) mirror-references to mirror_references for consistency Existing configuration files will keep working for now since the old name with dashes is still recognized by the config parser.

rename got.conf(5) fetch-all-branches to fetch_all_branches for consistency Existing configuration files will keep working for now since the old name with dashes is still recognized by the config parser.

create and verify tags signed by SSH keys This adds a new -s flag to 'got tag' that specifies the signer identity (for example, a key file) of the tagger. The tag object will include a signature that validates each of the tag object headers and the tag message. Verifying these signed tags requires maintaining an allowed signers file which maps signer identities (i.e. the email address of the tagger) to SSH public keys. See ssh-keygen(1) for more details of the allowed signers file. After creating this file and providing the path to it in got.conf(5) using the allowed_signers option, tags may be verified using with 'got tag -V tag_name'. The return code will be non-zero if a signature fails to verify. ok stsp@
