* mergetools/meld: improve compatibiilty with Meld on macOS XDavid Aguilar2017-06-18
| | | | | | | | | | | | | | | | | | | | | | | | The macOS X fork of Meld[1] requires a "=" in the "--output" argument, as it uses a wrapper[2] script that munges the "--output" argument before calling into the common "meld" script. The macOS X wrapper script[2] accepts "--output=<filename>" only, despite the fact that the underlying meld code accepts both "--output <filename" and "--output=<filename>"[3]. All versions of meld which accept "--output" accept it in the "--output=<filename>" form, so use "--output=<file>" for maximum compatibility.

* | mergetools/vimdiff: trust Vim's exit codeDavid Aguilar2016-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow vimdiff users to signal that they do not want to use the result of a merge by exiting with ":cquit", which tells Vim to exit with an error code. This is better than the current behavior because it allows users to directly flag that the merge is bad, using a standard Vim feature, rather than relying on a timestamp heuristic that is unforgiving to users that save in-progress merge files. The original behavior can be restored by configuring mergetool.vimdiff.trustExitCode to false.

* | mergetool: honor mergetool.$tool.trustExitCode for built-in toolsDavid Aguilar2016-11-29
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | Built-in merge tools contain a hard-coded assumption about whether or not a tool's exit code can be trusted to determine the success or failure of a merge. Tools whose exit codes are not trusted contain calls to check_unchanged() in their merge_cmd() functions. A problem with this is that the trustExitCode configuration is not honored for built-in tools. Teach built-in tools to honor the trustExitCode configuration. Extend run_merge_cmd() so that it is responsible for calling check_unchanged() when a tool's exit code cannot be trusted. Remove check_unchanged() calls from scriptlets since they are no longer responsible for calling it. When no configuration is present, exit_code_trustable() is checked to see whether the exit code should be trusted. The default implementation returns false. Tools whose exit codes can be trusted override exit_code_trustable() to true.

* mergetool: reorder vim/gvim buffers in three-way diffsDickson Wong2016-02-12
| | | | | | | | | | | | | | | | When invoking default (g)vimdiff three-way merge, the merged file is loaded as the first buffer but moved to the bottom as the fourth window. This causes a disconnect between vim commands that operate on window positions (e.g. CTRL-W_w) and those that operate on buffer index (e.g. do/dp). This change reorders the buffers to have the same index as windows while keeping the cursor default to the merged result as the bottom window.

* | mergetools/p4merge: create a base if none availableKevin Bracey2013-03-13

Unfortunately this approach produces much worse results on differing inputs. P4Merge really regards the blank file as the base, and once you have just a couple of differences between the two branches you end up with one a massive full-file conflict. The 3-way diff is not readable, and you have to invoke "difftool MERGE_HEAD HEAD" manually to get a useful view. The original approach appears to have invoked special 2-way merge behaviour in P4Merge that occurs only if the base filename is "" or equal to the left input. You get a good visual comparison, and it does not auto-resolve differences. (Normally if one branch matched the base, it would autoresolve to the other branch). But there appears to be no way of getting this 2-way behaviour and being able to reliably save. Having base==left appears to be triggering other assumptions. There are tricks the user can use to force the save icon on, but it's not intuitive. So we now follow a suggestion given in the original patch's discussion: generate a virtual base, consisting of the lines common to the two branches. This is the same as the technique used in resolve and octopus merges, so we relocate that code to a shared function. Note that if there are no differences at the same location, this technique can lead to automatic resolution without conflict, combining everything from the 2 files. As with the other merges using this technique, we assume the user will inspect the result before saving.

* | mergetools/p4merge: swap LOCAL and REMOTEKevin Bracey2013-03-13
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reverse LOCAL and REMOTE when invoking P4Merge as a mergetool, so that the incoming branch is now in the left-hand, blue triangle pane, and the current branch is in the right-hand, green circle pane. This change makes use of P4Merge consistent with its built-in help, its reference documentation, and Perforce itself. But most importantly, it makes merge results clearer. P4Merge is not totally symmetrical between left and right; despite changing a few text labels from "theirs/ours" to "left/right" when invoked manually, it still retains its original Perforce "theirs/ours" viewpoint. Most obviously, in the result pane P4Merge shows changes that are common to both branches in green. This is on the basis of the current branch being green, as it is when invoked from Perforce; it means that lines in the result are blue if and only if they are being changed by the merge, making the resulting diff clearer. Note that P4Merge now shows "ours" on the right for both diff and merge, unlike other diff/mergetools, which always have REMOTE on the right. But observe that REMOTE is the working tree (ie "ours") for a diff, while it's another branch (ie "theirs") for a merge. Ours and theirs are reversed for a rebase - see "git help rebase". However, this does produce the desired "show the results of this commit" effect in P4Merge - changes that remain in the rebased commit (in your branch, but not in the new base) appear in blue; changes that do not appear in the rebased commit (from the new base, or common to both) are in green. If Perforce had rebase, they'd probably not swap ours/theirs, but make P4Merge show common changes in blue, picking out our changes in green. We can't do that, so this is next best.

This change was necessary because of MSYS path mangling [1], the ":" after the "base" etc. arguments to TortoiseMerge caused the whole argument instead of just the file name to be quoted in case of file names with spaces. So TortoiseMerge was passed "-base:new file.txt" instead of -base:"new file.txt" (including the quotes). To work around this, TortoiseGitMerge does not require the ":" after the arguments anymore which fixes handling file names with spaces [2] (as written above).

Alas, it misdetects old versions (before 1.1.5, 2006-06-11) of meld as supporting the option, so on systems with such meld, instead of getting a nice merge helper, the operator gets a dialog box with the text "Wrong number of arguments (Got 5)". (Version 1.1.5 is when meld switched to using optparse. One consequence of that change was that errors in usage are detected and signalled through the exit status even when --help was passed.) Luckily there is a simpler check that is more reliable: the usage string printed by "meld --help" reliably reflects whether --output is supported in a given version. Use it.
