* ui-diff: make diffstat header a link to the full diffLars Hjemli2008-09-23
| | | | | | | | When printing a path-filtered diff it wasn't obvious how to get back to the full diff (clicking the 'diff' tab would do this). Making the diffstat heading into a link seems to improve the usability. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
* ui-diff: fix links from diffstatLars Hjemli2008-09-23
| | | | | | | | | | | The links in the diffstat is supposed to work as a filter for the diff, but this only worked when a single rev was supplied, i.e. the filtered diff was always against the parent of the specified rev. With this patch it is now possible to use the diffstat as a 'filter menu' for urls like http://hjemli.net/git/cgit/diff/?id=v0.7.2&id2=v0.7.1 Signed-off-by: Lars Hjemli <hjemli@gmail.com>

* ui-repolist: enable filtering of repos by pathLars Hjemli2008-09-15
| | | | | | | If a repo url is specified but no exact match is found in the list of repos the url will now be used as a prefix-filter. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
* Add support for --scan-tree=<path> option to cgitLars Hjemli2008-09-15
| | | | | | | This option makes cgit scan a directory tree looking for git repositories, generating suitable definitions for a cgitrc file on stdout. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
* Teach cgit how to use PATH_INFOLars Hjemli2008-09-15
| | | | | | | | | | | This commit makes cgit use the cgi variables SCRIPT_NAME and PATH_INFO when virtual-root is unspecified in cgitrc and no url-parameter is specified on the querystring. This has two nice effects: * Virtual urls works out of the box, no more need for rewrite-rules in httpd. * Virtual urls with special querystring characters are handled correctly.

| * parsing.c: be prepared for unexpected content in commit/tag objectsLars Hjemli2008-09-15
| | | | | | | | | | | | | | | | When parsing commits and tags cgit made too many assumptions about the formatting of said objects. This patch tries to make the code be more prepared to handle 'malformed' objects. Signed-off-by: Lars Hjemli <hjemli@gmail.com>

| * use Host: header to generate cgit_hosturlEric Wong2008-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I run an instance of lighttpd for cgit behind nginx (nginx doesn't execute CGI). So the port (SERVER_PORT=33333) that lighttpd runs on sends to cgit is different from the standard port 80 that public clients connect to (via nginx). This was causing the Atom feed URL to show the private port number that lighttpd was running on. Since the HTTP/1.1 "Host" header includes the port number if running on a non-standard port, it allows non-client-facing HTTP servers to transparently generate public URLs that clients can see. So use the "Host" header if it is available and fall back to SERVER_NAME/SERVER_PORT for some clients that don't set HTTP_HOST. Signed-off-by: Eric Wong <normalperson@yhbt.net>

| | | | | | | | | | | | | | | | | | | | | | The urls for plain view makes it possible to download blobs without knowing their SHA1, but the function needs to be promoted and the link from tree view seems like a perfect fit. PS: Although hidden, the blob view still is nice for direct blob access so there's no point in removing it. Signed-off-by: Lars Hjemli <hjemli@gmail.com>

* | Makefile: Git dependency, take 3Lars Hjemli2008-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | In commit a1266edfe the build instructions for the git libs where moved to their real targets, which in turn depended on the phony target `git`. But since `git` is an actual directory in cgit the git libs wouldn't be recompiled when needed. So with this patch (third time lucky), cgit is declared to depend on the really phony target `libgit` and the build instructions for `libgit` is to unconditionally rebuild git/libgit.a and git/xdiff/lib.a.

* Makefile: another take on git dependency rulesLars Hjemli2008-08-01
| | | | | | | | | | | | | | | When building cgit we depend on xdiff/lib.a and libgit.a in the git directory, but the previous attempt on describing this dependency failed since the build instructions for the libs was placed under the phony `git` target. This patch fixes the issue by moving the build instructions to their real targets. It also makes it clear that only the `cgit` target depends on the git binaries (since they're only used during linking). And while at it, the patch also cleans up the list of phony targets.

* Modify default value for a few cgitrc optionsLars Hjemli2008-07-27
| | | | | | | | | | | The default max-length used when printing commit messages and repo descriptions can be increased due to the new layout (no sidebar). Also, on the repo summary page I believe it makes sense to only show the ten most recent branches and tags by default, just as it makes sense to show the ten most recent commit messages for the active branch.
