gotwebd: fix some got_error_from_errno2/3 calls it's not printf-like so %s don't make sense. Tweak the order of the arguments to obtain the intended output.

gotwebd: avoid needless double fseek() got_gotweb_closefile() already takes care of rewinding before truncating and closing, so no need to replicate here. ok stsp@

gotwebd: lower log priority of unexpected disconnections no need to be so loud when a client disconnects earlier than expected, log it only in verbose mode. Don't log GOT_ERR_CANCELLED too since that is only used to communicate the callers that we need to stop. ok stsp@

oops, one was missing

got_operations.c: use consistently a space before labels makes diff prettier and easier to read; instead of the label we have the function name in the hunk line.

remove fsync() from got_gotweb_closefile() discussed with millert@

rename got_gotweb_flushfile -> got_gotweb_closefile suggested and ok millert@

make got_gotweb_flushfile always close the file ok millert@

rename some local fdN vars after previous change

simplify got_gotweb_openfile/flushfile Return only the FILE *, and require only that to close subsequently. Having to manage the file descriptor too makes using these functions unnecessary complex. millert@ agrees

include sha2.h too where sha1.h is included In preparation for wide sha256 support; stsp@ agrees. Change done mechanically with find . -iname \*.[cy] -exec sam {} + X ,x/<sha1\.h>/i/\n#include <sha2.h>

gotwebd: abort tree and blob as well

gotwebd: abort blame if the client disconnect midway thru Without setting err when the callback fails we continue the blame machinery.

fix mistaken instances returning NULL instead of err While here, for consistency, check dup() return value for -1 rather than < 0. ok stsp@

gotwebd: fix briefs/tags navigation overlap Introduces a separate field for the "next" button (now called "More") and adjusted the CSS/HTML so it's used. Finally, drops the old code used to handle the pagination for the BRIEFS/COMMITS cases. Needs a small hack for the time being, setting the action to TAGS. This is due how qs->action is changed in gotweb.c while handling the request. ok jamsek

gotwebd: delete always-true check ok stsp@

gotwebd: avoid full history traversal in briefs/commits This purposefully breaks the 'previous' button in the commits and briefs page. It's hard to find the parent of a commit since they can only be iterated forward. The way the previous button was generated was to walk the history from the HEAD down to the specified commit. This is costly but more importantly leads to issue when dealing with paths that were deleted from the repository. Discussed with stsp and tracey, ok jamsek.

gotwebd: don't got_ref_list per-commit in got_get_repo_commits It's wasteful since `refs' is already populated before the loop, and released after. It also leaks the content of `refs' the first time the loop is entered. ok jamsek

gotwebd: turn gotweb_get_time_str into gotweb_render_age ok jamsek

refactor got log -d and tog diffstat to compute diff once This eliminates the previous performance cost by making 'got log -d' and tog diff view compute the diffstat while building the diff in a temp file like we do with 'got diff -d'. Also, keep the current 'got log -d' UI as per stsp's suggestion. ok stsp@

gotwebd: inline got_output_file_blob into gotweb_process_request ok jamsek

gotwebd: templateify gotweb_render_blame ok and tweak from jamsek

gotwebd: templateify gotweb_render_diff ok tracey@; rebased after recent changes.

got: expand diffstat -d option to 'got diff' Like got log -d, add the switch to 'got diff' to display a diffstat of changes; as per stsp's suggestion, we always include diff output with the diffstat. Disabled in gotwebd (for now :) Includes tweaks from op@ ok stsp@
