* Support Git over HTTP by proxying git-http-backend(1)git-http-backendWolfgang Müller2021-05-28-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cgit lacks an easy way to support the "smart" HTTP protocol out of the box. A patch [1] has been proposed in the past, but was never merged. A few years later there was a short discussion at [2] which did not go anywhere. The majority of users who want to support the "smart" HTTP protocol right now seem to conditionally point their web server to git-http-backend(1) directly. This relies on proper path-matching and regular expression support in the web server as seen in the EXMAPLES section of git-http-backend(1). As proposed in [3], it is possible to have cgit interface with the necessary functionality in Git directly, but that would require more work. It does not seem that this is something forthcoming in cgit. Instead, for now, use a modified version of the patch suggested in [1], which simply executes git-http-backend(1) when needed. This removes the need for any additional plumbing in the web server. Notable changes to the original patch: * Remove automatic handling of GIT_PROJECT_ROOT in favour of having the user set the variable correctly themselves. This reduces complexity. * Use the correct function to generate error pages. The original patch used html_status(), which does not exist anymore. * In cmd.c, adjust the struct entries to fit. Sadly we cannot use the def_cmd() macro directly, as the endpoints "git-upload-pack" and "git-receive-pack" contain dashes.

* git: update to v2.25.0Christian Hesse2020-01-13-1/+1
| | | | | | | | | | Update to git version v2.25.0. Upstream renamed 'init_display_notes()' to 'load_display_notes()' in commit 1e6ed5441a61b5085978e0429691e2e2425f6846 ("notes: rename to load_display_notes()"). Signed-off-by: Christian Hesse <mail@eworm.de>

* filter: avoid integer overflow in authenticate_postJason A. Donenfeld2015-11-24-1/+1
| | | | | | | | | | | | ctx.env.content_length is an unsigned int, coming from the CONTENT_LENGTH environment variable, which is parsed by strtoul. The HTTP/1.1 spec says that "any Content-Length greater than or equal to zero is a valid value." By storing this into an int, we potentially overflow it, resulting in the following bounding check failing, leading to a buffer overflow.

* log: allow users to follow a fileJohn Keeping2015-08-12-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach the "log" UI to behave in the same way as "git log --follow", when given a suitable instruction by the user. The default behaviour remains to show the log without following renames, but the follow behaviour can be activated by following a link in the page header. Follow is not the default because outputting merges in follow mode is tricky ("git log --follow" will not show merges). We also disable the graph in follow mode because the commit graph is not simplified so we end up with frequent gaps in the graph and many lines that do not connect with any commits we're actually showing. We also teach the "diff" and "commit" UIs to respect the follow flag on URLs, causing the single-file version of these UIs to detect renames. This feature is needed only for commits that rename the path we're interested in. For commits before the file has been renamed (i.e. that appear later in the log list) we change the file path in the links from the log to point to the old name; this means that links to commits always limit by the path known to that commit. If we didn't do this we would need to walk down the log diff'ing every commit whenever we want to show a commit. The drawback is that the "Log" link in the top bar of such a page links to the log limited by the old name, so it will only show pre-rename commits. I consider this a reasonable trade-off since the "Back" button still works and the log matches the path displayed in the top bar. Since following renames requires running diff on every commit we consider, I've added a knob to the configuration file to globally enable/disable this feature. Note that we may consider a large number of commits the revision walking machinery no longer performs any path limitation so we have to examine every commit until we find a page full of commits that affect the target path or something related to it.

* Always check if README exists in choose_readme()Lukas Fleischer2014-08-07-6/+0
| | | | | | | | | | | | | Specifying a nonexistent README file via the readme option is sometimes useful, e.g. when using scan-path and setting a global default. Currently, we check whether there is only one option in the readme option and, if so, we choose that file without checking whether it exists. As a consequence, all repositories are equipped with an about link in the aforementioned scenario, even if there is no about file. Remove the early check for the number of keys and always check whether the file exists instead. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>

* Add a cache-snapshot-ttl configuration variableLukas Fleischer2014-02-20-0/+6
| | | | | | | | | | | | | This can be used to specify the TTL for snapshots. Snapshots are usually static and do not ever change. On the other hand, tarball generation is CPU intensive. One use case of this setting (apart from increasing the lifetime of snapshot cache slots) is caching of snapshots while disabling the cache for static/dynamic HTML pages (by setting TTL to zero for everything except for snapshot requests).
