2011-06-13cgit.c: add 'clone-url' setting with support for macro expansionLars Hjemli-0/+1
The current 'clone-prefix' setting has some known issues: * All repos get the same 'clone-prefix' value since the setting is not adopted during repo registration (in cgitrc, or during scan-path traversal), but only when the setting is used. * The generated clone-urls for a repo is a combination of 'clone-prefix', a slash and the repo url. This doesn't work well with e.g. ssh-style urls like 'git@example.org:repo.git', since the inserted slash will make the repo relative to the filesystem root. * If 'remove-suffix' is enabled, the generated clone-urls will not work for cloning (except for http-urls to cgit itself) since they miss the '.git' suffix. The new 'clone-url' setting is designed to avoid the mentioned issues: * Each repo adopts the default 'clone-url' when the repo is defined. This allows different groups of repos to adopt different values. * The clone-urls for a repo is generated by expanding environment variables in a string template without inserting arbitrary characters, hence any kind of clone-url can be generated. * Macro expansion also eases the 'remove-suffix' pain since it's now possible to define e.g. 'clone-url=git://foo.org/$CGIT_REPO_URL.git' for a set of repos. A furter improvement would be to define e.g. $CGIT_REPO_SUFFIX to '.git' for all repos which had their url prettified, or to store the original $CGIT_REPO_URL in e.g. $CGIT_REPO_REAL_URL before suffix removal.

2011-06-13cgit.c: always setup cgit repo environment variablesLars Hjemli-4/+3
When cgit learned to setup environment variables for certain repo settings before invoking a filter process, the setup occurred inside cgit_open_filter(). This patch moves the setup out of cgit_open_filter() and into prepare_repo_cmd() to prepare for additional uses of these variables.

2011-03-26shared.c: use execvp() to execute filter commandsLars Hjemli-57/+11
This reintroduces the use of execvp(), since the filter commands doesn't always contain an absolute path (i.e. snapshot compression filters). Signed-off-by: Lars Hjemli <hjemli@gmail.com>
2011-03-26cgit_open_filter: hand down repo configuration to scriptFerry Huberts-1/+77
The environment variables can be used to (for example) resolve the following situation: Suppose a server setup in which each repository has a trac instance; the commit filter needs to know with which repository it's dealing in order to be able to resolve the #123 ticket numbers in the commit messages into hyperlinks into the correct trac instance.

2010-11-16ui-log: Implement support for commit graphsJohan Herland-0/+1
Teach CGit to print an ASCII art commit graph to the left of the commit message, similar to 'git log --graph'. The graph adds extra lines (table rows) to the log when needed to add/remove/shuffle edges in the graph. When 'showmsg' is enabled, the graph is automatically padded to account for the extra lines added by the commit message/notes. This feature is controlled by a new config variable: "enable-commit-graph" (disabled by default), and individual repos can control it by setting "repo.enable-commit-graph".

2010-11-09ui-log: Fix filecount/linecount when path limit is in effectJohan Herland-2/+2
When using ui-log with path limits, the listing of commits enables parent rewriting in Git's internal log machinery. This did not work well together with cgit_diff_commit() which is used to generate the filecount and linecount numbers for each commit in the log view. cgit_diff_commit() would operate without any path limits, and would therefore process the full diff between the commits shown (which, because of parent rewriting, is not the same as processing the diff for the commit itself). Additionally, the bottom commit in the log view would (again, because of parent rewriting) have zero parents, causing us to process the entire diff between the empty tree and that commit. Since path limits were not in effect, this would (in large projects) reports thousands of files and millions of lines changed in that bottom commit. This patch fixes the issue by applying the same path limit to cgit_diff_commit() as is applied to the rest of the log view. The result is that the filecount/linecount now only reflects the diff as it pertains to the given path limit.

2010-03-22Add support for environment variable expansionLars Hjemli-0/+71
This patch teaches cgit to expand environment variables in certain cgitrc option values (cache_root, scan-path, include) plus when finding the location of cgitrc itself. One use case for this feature is virtual hosting - e.g. by setting $CGIT_CONFIG='/etc/cgitrc/$HTTP_HOST' in httpd.conf, all virtual hosts automatically gets their own cgitrc.

2008-12-07ui-stats: replace 'enable-stats' setting with 'max-stats'Lars Hjemli-1/+1
The new 'max-stats' and 'repo.max-stats' settings makes it possible to define the maximum statistics period, both globally and per repo. Hence, it is now feasible to allow statistics on repositories with a high commit frequency, like linux-2.6, by setting repo.max-stats to e.g. 'month'. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
2008-12-06Add a 'stats' page to each repoLars Hjemli-0/+1
This new page, which is disabled by default, can be used to print some statistics about the number of commits per period in the repository, where period can be either weeks, months, quarters or years. The function can be activated globally by setting 'enable-stats=1' in cgitrc and disabled for individual repos by setting 'repo.enable-stats=0'. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
2008-11-29ui-repolist: implement lazy caching of repo->mtimeLars Hjemli-0/+1
When sorting the list of repositories by their last modification time, cgit would (in the worst case) invoke fstat(3) four times and open(3) twice for each callback from qsort(3). This obviously scales very badly. Now, the calculated modtime for each repo is saved in repo->mtime, thus keeping the number of stat/open invocations identical for sorted and unsorted repo-listings.

2008-03-24Add struct cgit_page to cgit_contextLars Hjemli-0/+3

2008-03-18Introduce html.hLars Hjemli-2/+0

This adds support for two new parameters to cgitrc: clone-prefix and repo.clone-url. If clone-prefix is specified, all repos will get a clone url printed in the sidebar; the url is generated by clone-prefix + repo.url. Additionally, each repo can specify repo.clone-url which will override any such auto-generated url. Signed-off-by: Lars Hjemli <hjemli@gmail.com>

2007-11-08Support "/" as virtual-rootLars Hjemli-2/+4
When the virtual-root was a single "/", it would be normalized to NULL due to removal of trailing slashes, which in turn would fool us to belive that we shouldn't generate virtual urls. This makes the "/" normalize to "", effectively allowing virtual urls like http://example.com/projectname to be generated without specifying the full domain name as the virtual root.

This modifies and hopefully improves the layout of all cgit pages: * Remove the header from all pages and replace it with a sidebar; most pages have sufficient width but many needs more height. * Add a dropdown-box to switch between branches, using a one-liner javascript to reload the current page in context of the selected branch. * Include refs found below refs/archives in the sidebar, appearing as a set of menuitems below a 'download' heading. * Include the brand new cgit logo Signed-off-by: Lars Hjemli <hjemli@gmail.com>
