fix diff and log diffstat tests broken in 65dedee0a2cd I failed to update regress when changing the diffstat summary line in the previous commit to use a singular noun after 1. ok op@ and stsp@

update gotd TODO items

don't use plural noun after 1 in diffstat total Use singular form when appropriate; for example, turn the top into the bottom: 1 file changed, 1 insertions(+), 1 deletions(-) 1 file changed, 1 insertion(+), 1 deletion(-) ok op@

gotwebd: delete now unused code gotweb_escape_html and gotweb_link are now completely unused. ok jamsek

gotwebd: inline got_output_file_blob into gotweb_process_request ok jamsek

gotwebd: templateify gotweb_render_blame ok and tweak from jamsek

zap empty line

gotwebd: templateify gotweb_render_summary ok jamsek

gotwebd: bubble up got_get_repo_tags This bubbles up the call to got_get_repo_tags from gotweb_render_tags to its caller, gotweb_process_request and gotweb_render_summary. It helps simplifying gotweb_render_summary and making it easier to templateify, but also helps in untangling a bit the code. At this point gotweb_render_tags becomes just a wrapper to gotweb_render_tags_tmpl so switch completely to it. ok jamsek

gotwebd: templateify gotweb_render_branches no functional change intended. Bubble up the allocation of the reflist from gotweb_render_branches to gotweb_render_summary (its only caller) and rewrite it as a template. ok tracey@

got: style(9) and cleanup failure leaks lib/diff.c Spotted while implementing diffstat plus one introduced with diffstat code. Don't leak 'change' on got_pathlist_append() error. And don't leak modestr{1,2} and l{1,2} char pointers in diff_blobs() and got_diff_tree(), respecitvely. Regarding modestr leaks, rather than free at all error return points, use op's suggestion to lift modestr vars to function scope. ok op@

got: set error on asprintf() failure ok op@

replace malloc+memcpy with strndup. no functional change intended ok stsp@

got.1: Add example which lists recently modified branches. I use this a lot.

use just one pointer variable to keep track of a client's repo process ok op@

update client state tracking in the gotd parent process The session process takes over the old state definitions under a new name ("session state"). The parent only needs to keep track of whether a client has been granted access, so it only uses two states: NEW, and ACCCESS_GRANTED which is set as soon as the auth process has granted repository access and before the session and repo_read/repo_write children are started. Because 'gotctl info' can no longer observe the session state remove support code for printing it. ok op@

gotd: delete trailing blanks spotted while re-reading

gotwebd: show committer instead of author in BRIEFS

gotwebd: use from/via in gotweb_render_commits too like the previous, show also the committer if different from the author.

gotwebd: make commit page more like `got log' / tog - drop the "diff commit1 commit2" header; it's already showed in the body of the diff. - hide the tree id (not that useful to show.) - show the committer if different from the author. - use From/Via for Committer/Author. discussed with jamsek, stsp, tracey ok jamsek tracey

remove support for showing client capabilities in 'gotctl info' The gotd parent process has lost access to client capabilities. Take the easy way out and remove related code. If needed, client capabilities can still be found in the debug log with 'gotd -v'. ok op, jamsek

tog: fix {first,last}_displayed_line dead store Both are already assigned just above in open_diff_view() ok op@

typo: pass rejectfile--not outfile--to got_ferror() ok stsp@

catch a few missed got_pathlist_append() error checks ok stsp@

typo: zap double semi-colon
