Read a negative ref count as no limitBryce Kwon-4/+4
summary-branches, summary-tags and max-ref-count already listed every ref at 0, but a negative value reached qsort as a count and crashed the summary and refs pages, and emptied the branch switcher.
Add blame to the source filter and line number docsBryce Kwon-9/+9
Name every trailer link-trailers.lua linksBryce Kwon-3/+3
Say that js may be given more than onceBryce Kwon-2/+4
Add html serving to the scanned cgitrc trust listBryce Kwon-3/+4
1456483 gated the key and named it under trust-scan-config, but this section kept the list from before.
Describe root-readme as the site's about pageBryce Kwon-13/+15
Say which filters get the repository variablesBryce Kwon-1/+3
Leave readme out of what scan-path fixesBryce Kwon-3/+5
Name the log link that enable-index-links addsBryce Kwon-1/+1
The manual has named the commit page since it was written in 2008, a year after the index started linking the log instead.
Hand the about filter the tree url its links needBryce Kwon-11/+17
With nothing below the about page, a readme's relative links have to be written against the tree, and only cgit knows how this site spells the url of a tree page and which ref the readme was read from. Both reach the filter already escaped for a url, built by the same writer as cgit's own links.
Answer 404 for any path below the about pageBryce Kwon-4/+1
The about page served every file beside the readme as a page of its own, through the about filter, and answered 200 for directories and missing files alike. Images it passed through came from the root of the default branch whatever the readme's own directory and ref. A readme on disk exposed its whole directory this way.
Keep date-format=local-local from failing pagesBryce Kwon-6/+6
The guard took local as a name that may carry the -local suffix, but git reads local only as a whole alias of default-local and dies on anything after it, so that one value turned every page into a 500.
Keep clone files and oversized responses out of the cacheBryce Kwon-2/+11
The dumb transport reads files that already sit on the disk, so a pack copied into a slot cost that disk twice and the request a second write of every byte. A snapshot took a slot whatever its size, so a visitor naming distinct refs and ids could fill the cache root with archives. `cache-max-slot-size`, 64 MB unless set, now serves a larger response from the lock file and drops it, along with any expired copy it would have replaced.
Gate html serving behind trust-scan-configBryce Kwon-7/+10
`enable-html-serving` makes the plain page send a repository file as text/html on the site's own origin, with no nosniff and no policy, so a scanned repository could switch it on from its git config or cgitrc without `trust-scan-config` and run script against every visitor. The warning for a key read from git config also named a null repository, because `repo->path` was set only after that file had been read.
Keep the Lua-less build compilingBryce Kwon-1/+2
`cgit_abort_filters` unhooks the Lua write interposer under NO_LUA too, where neither the hook nor its state exists, so `make NO_LUA=1` and the default mode of `tools/release-build.sh` have not compiled since the die path learned to take stdout back from a filter. The suite now builds that variant into `build/nolua` and runs it, and a `lua:` filter in such a build is refused with a message naming the cause instead of an unknown filter type.
Rename enable-trailers to enable-commit-trailersBryce Kwon-22/+22
Unify the docs, samples and extensionsBryce Kwon-212/+201
Harden the request path, scan and error recoveryBryce Kwon-19/+22
Gate scanned filters with `trust-scan-filters`Bryce Kwon-26/+25
Apply the mailmap at HEAD to every identBryce Kwon-0/+13
Split trailers out of the commit messageBryce Kwon-0/+38
Trim the comments and dead code across the treeBryce Kwon-2/+2
Convert the manual page to plain `MANUAL.txt`Bryce Kwon-0/+903
Beyond the format change, the documented defaults and inheritance notes now match what the code does.
