gotwebd: reply with non-200 HTTP status code on error ok tracey@

gotwebd: provide gotweb_render_page() entrypoint for all pages simplify gotweb_process_request more, handling all the pages inside the big switch. There's only one entrypoint for rendering the templates gotweb_render_page() that takes the page' content as argument. The only real difference is that gotweb_render_index() now skips directory entries which fails to handle. ok tracey@

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: turn gotweb_get_time_str into gotweb_render_age ok jamsek

gotwebd: refactor gotweb_render_content_type/_file Rework them so that they allow to set the Status header (the HTTP status code; only way since we're behind FastCGI) and optionally a Location. Since they're now unused outside of gotweb.c, mark them as static. They also used to always return NULL so the error is pointless; return the -1 on failure though. While here, rename to gotweb_reply and gotweb_reply_file. ok jamsek

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

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@

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

gotwebd: templateify gotweb_render_tag ok tracey@

gotwebd: templateify gotweb_render_tags ok tracey@

backout 169b163113a6db9878c9166aa05fbd30d05eb832 pushed by mistake, wasn't reviewed.

gotwebd: templateify gotweb_render_diff To avoid calling functions from got_operations.c directly from a template (which would hide the error), change got_output_repo_diff into got_open_diff_for_output that returns a file with the diff in it, to be then rendered by the template. got_gotweb_flushfile needs to be exposed then. It also bundles a smaller change: the `label' argument of got_repo_match_object_id is optional and not used, so just pass NULL there.

gotwebd: templateify gotweb_render_tree ok tracey@

gotwebd: render BLOB inline, add BLOBRAW for serving raw blobs binary blobs are automatically redirected to the BLOBRAW page (which is the old BLOB.) ok jamske

change gotweb_render_content_type argument type to const char * it's a string, `const char *' is fine (and what all the callers use anyway.)

gotwebd: use Content-Disposition for RSS; sets the filename Since gotwebd serves the RSS from a path without a file name component, browsers just make up a random string to give the file a name which can be confusing. Furthermore, since it's served as application/rss+xml they try to render the XML (failing.) Use gotweb_render_content_type_file (which sets the Content-Disposition HTTP header) to fix both: the feed is now called <repo-name>.rss and set as attachment (thus saved and not rendered.) Change the function to take an optional filename suffix for the occasion. ok jamsek

gotwebd: tweak gotweb_render_content_type_file parameters type `type' and `file' are strings so use `const char *' for both.

gotwebd: add an RSS feed for the tags ok tracey@

gotwebd: use DOCUMENT_URI rather than SCRIPT_NAME the latter is empty when serving from a directory-like path prefix with an httpd.conf(5) as per gotwebd(8). ok tracey@

gotwebd: templateify gotweb_render_commits ok tracey@

gotwebd: templateify gotweb_render_navs ok tracey@
