* | shared.c: Only setenv() if value is non-nullLukas Fleischer2012-01-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some setenv() implementations (e.g. the one in OpenBSD's stdlib) segfault if we pass a NULL value. Only set environment variables if the corresponding settings are defined to avoid this. Note that this is a minor behaviour change as environment variables were supposed to be set to an empty string if a setting was undefined. Given that this feature isn't part of any official release yet, there's no need to worry about backwards compatibility, really. Change the documentation accordingly.

* cgit.c: add 'clone-url' setting with support for macro expansionLars Hjemli2011-06-131-0/+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.

* cgit.c: always setup cgit repo environment variablesLars Hjemli2011-06-131-4/+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.

* ui-log: Implement support for commit graphsJohan Herland2010-11-161-0/+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".

* ui-log: Fix filecount/linecount when path limit is in effectJohan Herland2010-11-091-2/+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.
