2009-05-16gitk: Make more options easily accessible from Edit View dialogLibravatar Elijah Newren1-37/+94
Commit 218a900bd8efd0d49f8a0d9491aa4786a998d4f4 added a number of new individual fields for the Edit View dialog to make them more accessible to end users, while still allowing all options to be specified in the "arguments to git log" field. This extends the dialog further, to include refs, author, committer, commit message, and patch contents. As before everything still remains accessible from the "arguments to git log" input field. Additionally, this provides hints for the format of the various input fields (for example, listing some sample date strings in different formats), and puts related query items into subsections to make it easier to digest the number of options that exist.

2009-05-16gitk: Check git version before using --textconv flagLibravatar Paul Mackerras1-1/+7
Commit 785b7535 ("gitk: use --textconv to generate diff text") added the --textconv flag to the git diff commands used to display commit diffs. Since some people use newer gitk with older git installations, this adds a check on the git version to check that it understands --textconv before using it.

2009-05-16gitk: Use --textconv to generate diff textLibravatar Johannes Sixt1-1/+1
For the most part gitk's focus is on showing history and changes in a human readable form. For this reason, it makes sense to generate the patch text in the diff view using --textconv so that textconv drivers are used if they are defined. gitk can also generate patches, but we do not use --textconv because such patches could not be applied.

2009-04-21gitk: Fix compare-commits function when we have local changesLibravatar Paul Mackerras1-19/+47
This fixes a bug in the compare-commits function added in commit 010509f2 ("gitk: Add a command to compare two strings of commits") where gitk would show an error dialog if the comparison of commits got to a fake commit (one showing local changes). It extends getpatchid to handle these fake commits by using [diffcmd] to get the git diff command variant to use, and also handles the situation where an error occurs. Now that we can have the fake commit IDs showing up, which are 00..00 and 00..01, the short ID is ambiguous. To make sure the links point to the right commit, this adds a new [appendshortlink] procedure which takes the full link destination, and uses that rather than appendwithlinks.

2009-04-17gitk: Handle external diff tool with spaces in the pathLibravatar Pat Thoyts1-3/+2
This fixes the launching of external diff to handle a diff tool that has spaces in the path. This ensures a correctly formed tcl list is passed to the open command with a single pipe character prefixing the list (as per the tcl manual page for open). The specific fault observed was that selecting WinMerge as the diff tool from the default installed location in Program Files failed to be launched from the context menu.

2009-04-09gitk: Add a command to compare two strings of commitsLibravatar Paul Mackerras1-0/+89
This adds a row context menu command to compare this commit and its descendants with the marked commit and its descendants. The results are shown in the bottom-left pane. Commits are compared by checking whether their headlines are the same and their patches have the same patch ID as generated by git patch-id. Merges are ignored and skipped over (as long as they have one descendant). If two commits have the same patch ID then the process will continue and compare their descendants, as long as they both have exactly one descendant. If either commit has 0 or 2 or more descendants, the comparison stops there. There is currently a limit of 100 comparisons. This can be useful for checking whether one string of commits is just a rebased version of another string of commits. Mark the end of one string (i.e. the oldest commit in the string) and invoke "Compare with marked commit" on the end of the other string. As this is implemented, the UI will be unresponsive while the results are being generated. This should be fixed. Signed-off-by: Paul Mackerras <paulus@samba.org>
2009-04-09gitk: Add a way to mark a commit, plus a "find descendant" commandLibravatar Paul Mackerras1-4/+87
This adds a context-menu command to put a mark on this commit. There is at most one marked commit at any time, and it is indicated by a box drawn around the headline. Once a commit is marked, two other context-menu commands become available: one to select the marked commit, and another to find the closest common descendant of this commit and the marked commit. The "find common descendant" command uses the displayed parent/child relationships (i.e. the rewritten parent pointers produced by git log), not the real parent/child relationships. Currently the UI will be unresponsive while gitk is working out the nearest common descendant; this should be improved in future. Signed-off-by: Paul Mackerras <paulus@samba.org>

This recipe created a situation where git log would output a child commit after its parent. This meant that we called fix_reversal which called splitvarc, which should call modify_arc to note the fact that it has modified the arc that it has just split. It wasn't, which meant that displayorder and other variables got into an inconsistent state (a commit appearing twice in displayorder). This then meant that the targetrow/targetid logic in drawvisible thought it need to redraw each time. That, together with the fact that drawvisible called drawcommits which called drawvisible if a redraw was needed, led to the infinite loop. In fact drawvisible is now the only caller of drawcommits. Thus, the start and end row arguments to drawcommits always encompass the whole visible area, so drawcommits doesn't need to call drawvisible to redraw; it just needs to clear the screen and draw what it's been asked to. This fixes these two problems by adding a call to modify_arc in splitvarc and by taking out the call to drawvisible in drawcommits. It also removes an unrelated left-over debugging puts in external_blame. Signed-off-by: Paul Mackerras <paulus@samba.org>

2008-12-06gitk: Fix bugs in blaming codeLibravatar Paul Mackerras1-3/+29
The "show origin of this line" function wasn't working when gitk was run in a subdirectory, since it passed the path relative to the top-level directory to git blame. This fixes it by passing the absolute path to the file instead of the relative path. The same problem occurs when running git gui blame, except that git gui blame appears not to be able to accept an absolute path to the file, so we make a relative path using a new [make_relative] function. Finally, this fixes a bug in [show_line_source] where we weren't setting id, resulting in an error when trying to find the origin of a line in the fake commit for local changes not checked in, when its parent was a real commit (i.e. there were no changes checked in).

2008-11-18gitk: Fix context menu items for generating diffs when in tree modeLibravatar Paul Mackerras1-1/+1
Currently, if you invoke the "diff this -> selected" or "diff selected -> this" and gitk is in "Tree" mode rather than "Patch" mode, the diff display pane will just show the header but not the actual diff, unless gitk has done the diff before and thus has the list of files that differ. This was because the logic in gettreediffline that checked whether we had moved on to doing something else checked the mode (Tree or Patch) before checking whether the ids we're diffing had changed. This fixes it. The new logic in gettreediffline is slightly hacky and relies on the fact that the Tree/Patch mode only applies when we're looking at a single commit, not at the diff between two commits.

A similar change was made as part of commit 76f15947af7, that added bindings to all dialogs, and this duplication causes mkbrgo to be called twice, the second time after the window has been destroyed.

2008-11-18gitk: Show local changes properly when we have a path limitLibravatar Paul Mackerras1-22/+88
Since gitk looks for the HEAD commit to attach the fake commits for local changes to, we can miss out on seeing the fake commits if we have a path limit and the HEAD commit doesn't alter any of the files in the path limit. This fixes it by running git rev-list -1 $head -- $paths if we have a path limit, and taking the result of that as the commit to attach the fake commits to. This means that we can be attaching the fake commits to a different commit in each view, so we use a new $viewmainhead($view) for that. This also fixes a buglet where updatecommits would only fix up the fake commits if the HEAD changed since the last call to updatecommits, whereas it should fix them up if the HEAD has changed since this view was last created or updated.

2008-11-13gitk: Fix linehtag undefined error with file highlightingLibravatar Paul Mackerras1-2/+5
Occasionally gitk will throw a Tcl error complaining that linehtag(n) is undefined when. It happens when the commit list is still growing (e.g. when updating the commit list) and gitk is set to highlight commits that affect certain file(s). What happens is that the changes to the commit list set need_redisplay to indicate that the display needs to be redrawn. That causes the next call to drawcommits to call clear_display, which unsets iddrawn and thus ensures that readfhighlight won't call bolden on any rows that have moved. However, it is possible for readfhighlight to be called after the commit list has changed but before drawcommits has run, meaning that readfhighlight will potentially think that rows have been drawn when they haven't, because of the change in the id -> row mapping (and the fact that iddrawn is indexed by id but line[hnd]tag are indexed by row number). This fixes it (and also optimizes things a little) by making bolden and bolden_name check need_redisplay before doing anything. If need_redisplay is set, then there is no point doing anything because the whole display is about to get cleared and redrawn, and it avoids looking up line[hn]tag using stale row numbers.

2008-11-13gitk: Fix commit encoding supportLibravatar Alexander Gavrilov1-2/+23
This commit fixes two problems with commit encodings: 1) git-log actually uses i18n.logoutputencoding to generate its output, and falls back to i18n.commitencoding only when that option is not set. Thus, gitk should use its value to read the results, if available. 2) The readcommit function did not process encodings at all. This led to randomly appearing misconverted commits if the commit encoding differed from the current locale. Now commit messages should be displayed correctly, except when logoutputencoding is set to an encoding that cannot represent charecters in the message. For example, it is impossible to convert Japanese characters from Shift-JIS to CP-1251 (although the reverse conversion works). The reason for using git log to read the commit and then getting Tcl to convert its output is that is essentially what happens in the normal path through getcommitlines, hence there is less chance for unintended differences in how commits are processed in getcommitlines and do_readcommit.

The changes include a workaround for handling Shift-F4 on systems where XKB binds special XF86_Switch_VT_* symbols to Ctrl-Alt-F* combinations.

2008-11-08gitk: Implement a user-friendly Edit View dialogLibravatar Alexander Gavrilov1-44/+163
Originally gitk required the user to specify all limiting options manually in the same field with the list of commits. It is rather unfriendly for new users, who may not know which options can be used, or, indeed, that it is possible to specify them at all. This commit modifies the dialog to present the most useful options as individual fields. Note that options that may be useful to an extent, but produce a severely broken view, are deliberately not included. It is still possible to specify options in the commit list field, but when the dialog is reopened, they will be extracted into their own separate fields.

Transient windows are always kept above their parent, and don't occupy any space in the taskbar, which is useful for dialogs. Also, when transient is used, it is important to bind windows to the correct parent.

This modifies gettreediffline so that it when we get both a "U" line and an "M" line for the same file in the output from git diff-files or git diff-index --cached (used when the user clicks on a fake commit) we don't add the same filename to the treediff list twice.

2008-11-04gitk: Make "show origin of this line" work on fake commitsLibravatar Paul Mackerras1-3/+61
This makes the "Show origin of this line" menu item work correctly on the fake commits that gitk shows for local uncommitted changes. With the fake commit for changes that aren't checked in to the index, we can actually get a 3-way diff shown, which means we might have to blame either the parent or the commit being merged in (which we get from .git/MERGE_HEAD). If the parent is the fake commit which shows the changes that have been checked in to the index, then we need to get the SHA1 of the blob for the version of the file that is in the index, then use git cat-file blob to get the contents of the blob, and give that to git blame with --contents - so that git blame will do the blame on the index version of the file. In that case, we might get the all-zeroes SHA1 back from git blame, meaning that the line is new in the index version of the file, so then we have to use $nullid2 (the pseudo-SHA1 of the fake commit for the checked-in changes).
