2015-08-12log: allow users to follow a fileJohn Keeping
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.

2014-12-30ui-diff: don't link to single file diff statJohn Keeping
Seeing the diff stat for a single file is pretty useless, so reset the diff type before generating the links to individual files in the diff stat so that the links will show a useful diff. Reported-by: Konstantin Ryabitsev <mricon@kernel.org> Signed-off-by: John Keeping <john@keeping.me.uk>
2014-12-13ui-diff: add "stat only" diff typeJohn Keeping
This prints the diffstat but stops before printing (or generating) any of the body of the diff. No cgitrc option is added here so that we can wait to see how useful this is before letting people set it as the default. Suggested-by: Konstantin Ryabitsev <mricon@kernel.org> Signed-off-by: John Keeping <john@keeping.me.uk>
2014-12-13Change "ss" diff flag to an enumJohn Keeping
This will allow us to introduce a new "stat only" diff mode without needing an explosion of mutually incompatible flags. The old "ss" query parameter is still accepted in order to avoid breaking saved links, but we no longer generate any URIs using it; instead the new "dt" (diff type) parameter is used. Signed-off-by: John Keeping <john@keeping.me.uk>
2014-12-13ui-shared: remove toggle_ssdiff arg to cgit_diff_link()John Keeping
This argument is never used with a value other than zero, so remove it and simplify the code. Signed-off-by: John Keeping <john@keeping.me.uk>
2014-01-16Switch to exclusively using global ctxLukas Fleischer
Drop the context parameter from the following functions (and all static helpers used by them) and use the global context instead: * cgit_print_http_headers() * cgit_print_docstart() * cgit_print_pageheader() Remove context parameter from all commands Drop the context parameter from the following functions (and all static helpers used by them) and use the global context instead: * cgit_get_cmd() * All cgit command functions. * cgit_clone_info() * cgit_clone_objects() * cgit_clone_head() * cgit_print_plain() * cgit_show_stats() In initialization routines, use the global context variable instead of passing a pointer around locally. Remove callback data parameter for cache slots This is no longer needed since the context is always read from the global context variable. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>

2013-09-14ui-diff: Use diff_tree_sha1() for raw diff formattingLukas Fleischer
Use Git's internal diff_tree_sha1() function for the /rawdiff/ command instead of trying to recreate this functionality. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
2013-08-20ui-diff: Check the return value of get_sha1()Lukas Fleischer
Sync with what we do everywhere else and check the return value of get_sha1() instead of calling sha1_object_info() to validate the object. Note that we later call lookup_commit_reference(), which checks that both SHA1 values refer to commits, anyway. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
2013-08-16Allow for creating raw diffs with cgit_print_diff()Lukas Fleischer
This adds a parameter to cgit_print_diff() to create raw diffs, using the same format as `git diff <commit>`. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
2013-04-08Convert cgit_print_error to a variadic functionJohn Keeping
This removes many uses of "fmt" which uses a fixed size static pool of fixed size buffers. Instead of relying on these, we now pass around argument lists for as long as possible before using a strbuf to render content of an arbitrary size. Signed-off-by: John Keeping <john@keeping.me.uk>
2013-04-08Always #include corresponding .h in .c filesJohn Keeping
While doing this, remove declarations from header files where the corresponding definition is declared "static" in order to avoid build errors. Also re-order existing headers in ui-*.c so that the file-specific header always comes immediately after "cgit.h", helping with future consistency. Signed-off-by: John Keeping <john@keeping.me.uk>

2012-11-14Format git diff headers correctly when adding or removing files.Michael Halstead
Copying the output of cgit and using it in patches now works when adding files to or removing files from the repository. This is helpful for people who use cgit in their patch workflow.
2012-01-03ui-ssdiff.c: set correct diffmode in "control panel"Tim Chen
When side-by-side-diffs=1 was set in cgitrc, specifying 'ss=0' in the querystring would not set the 'unified' option as active in the dropdown box used to select diffmode.

2012-01-03Fix diff mode switching when side-by-side-diffs=1Tim Chen
When side-by-side-diffs=1 was set in cgitrc, specyfing 'ss=0' in the query- string would not switch to unified diffs. This patch fixes the issue by introducing a separate variable to track the occurrence of "ss" in the querystring.

2011-05-23Avoid null pointer dereference in cgit_print_diff().Lukas Fleischer
When calling cgit_print_diff() with a bad new_rev and a NULL old_rev, checking for new_rev's parent commit will result in a null pointer dereference.

2010-09-04fix errors in printf-style format stringsMark Lodato
There were many places where the arguments to a printf-like function did not match the format string. Mostly, these were a missing 'l' flag, but there were three exceptions: - In ui-stats.c, a size_t argument must be printed. C99 has the "%zu" flag for this purpose, but not all compilers support this. Therefore, we mimic what git does - use a NO_C99_FORMAT Makefile variable. - In ui-stats.c, cgit_print_error() was called with a pointer instead of a character. - In ui-log.c, the "columns" argument was never used.

2010-07-18ui-diff: Add link to ignore/show whitespace changes in diffsJohan Herland

2010-07-18Add URL parameter 'ignorews' for optionally ignoring whitespace in diffsJohan Herland

2009-09-16Add possibility to switch between unidiff and side-by-side-diff.Ragnar Ouchterlony
A new config option side-by-side-diffs added, defaulting to 0, meaning unidiff. Also a query option (ss) is used toggle this. In the commit page you can switch between the two diff formats by clicking on the link on the "commit"-row, to the right of (patch). In the diff page you can switch by using the link at the start of the page. All commit-links and diff-links will remember the choice.

2008-09-23ui-diff: make diffstat header a link to the full diffLars Hjemli
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>
2008-09-23ui-diff: fix links from diffstatLars Hjemli
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>
