| * userdiff: add xdiff_clear_find_func()René Scharfe2009-07-01
| | | | | | | | | | | | | | | | | | | | | | | | xdiff_set_find_func() is used to set user defined regular expressions for finding function signatures. Add xdiff_clear_find_func(), which frees the memory allocated by the former, making the API complete. Also, use the new function in diff.c (the only call site of xdiff_set_find_func()) to clean up after ourselves.

* Allow users to un-configure rename detectionLinus Torvalds2009-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I told people on the kernel mailing list to please use "-M" when sending me rename patches, so that I can see what they do while reading email rather than having to apply the patch and then look at the end result. I also told them that if they want to make it the default, they can just add [diff] renames to their ~/.gitconfig file. And while I was thinking about that, I wanted to also check whether you can then mark individual projects to _not_ have that default in the per-repository .git/config file. And you can't. Currently you cannot have a global "enable renames by default" and then a local ".. but not for _this_ project". Why? Because if somebody writes [diff] renames = no we simply ignore it, rather than resetting "diff_detect_rename_default" back to zero. Fixed thusly.

However, the code reused the single set of metainfo lines. As the blob object names recorded on the index lines are usually not used nor validated on the receiving end, this is not an issue with normal use of the resulting patch. However, when accepting a binary patch to delete a blob, git-apply verified that the postimage blob object name on the index line is 0{40}, hence a patch that deletes a regular file blob that records binary contents to create a blob with different filetype (e.g. a symbolic link) failed to apply. "git am -3" also uses the blob object names recorded on the index line, so it would also misbehave when synthesizing a preimage tree. This moves the code to generate metainfo lines around, so that two independent sets of metainfo lines are used for the split halves. Additional tests by Jeff King.

However, if we want to clean up two _different_ things, we run into a problem. The most recently installed handler will run, but when it removes itself as a handler, it doesn't put back the first handler. This patch introduces sigchain, a tiny library for handling a stack of signal handlers. You sigchain_push each handler, and use sigchain_pop to restore whoever was before you in the stack.

The former cleans up its tempfiles in the face of premature death (i.e., by die() or by signal), but the latter does not. After this patch, they will both use the same cleanup routines. To make clear what the change is, let me first explain what happens now: - run_external_diff uses a static global array of 2 diff_tempfile structs (since it knows it will always need exactly 2 tempfiles). It calls prepare_temp_file (which doesn't know anything about the global array) on each of the structs, creating the tempfiles that need to be cleaned up. It then registers atexit and signal handlers to look through the global array and remove the tempfiles. If it succeeds, it calls the handler manually (which marks the tempfile structs as unused). - textconv has its own tempfile struct, which it allocates using prepare_temp_file and cleans up manually. No signal or atexit handlers. The new code moves the installation of cleanup handlers into the prepare_temp_file function. Which means that that function now has to understand that there is static tempfile storage. So what happens now is: - run_external_diff calls prepare_temp_file - prepare_temp_file calls claim_diff_tempfile, which allocates an unused slot from our global array - prepare_temp_file installs (if they have not already been installed) atexit and signal handlers for cleanup - prepare_temp_file sets up the tempfile as usual - prepare_temp_file returns a pointer to the allocated tempfile The advantage being that run_external_diff no longer has to care about setting up cleanup handlers. Now by virtue of calling prepare_temp_file, run_textconv gets the same benefit, as will any future users of prepare_temp_file. There are also a few side benefits to the specific implementation: - we now install cleanup handlers _before_ allocating the tempfile, closing a race which could leave temp cruft - when allocating a slot in the global array, we will now detect a situation where the old slots were not properly vacated (i.e., somebody forgot to call remove upon leaving the function). In the old code, such a situation would silently overwrite the tempfile names, meaning we would forget to clean them up. The new code dies with a bug warning. - we make sure only to install the signal handler once. This isn't a big deal, since we are just overwriting the old handler, but will become an issue when a later patch converts the code to use sigchain Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

To allow for that, you can specify a regular expression describing what makes a word with git diff --color-words='[A-Za-z0-9]+' Note that words cannot contain newline characters. As suggested by Thomas Rast, the words are the exact matches of the regular expression. Note that a regular expression beginning with a '^' will match only a word at the beginning of the hunk, not a word at the beginning of a line, and is probably not what you want.

Therefore, it could get away with a very simple scheme: it copied the hunks, substituted newlines for each white space character, called libxdiff with the processed text, and then identified the text to output by the offsets (which agreed since the original text had the same length). This code was ugly, for a number of reasons: - it was impossible to introduce 0-character word boundaries, - we had to print everything word by word, and - the code needed extra special handling of newlines in the removed part. Fix all of these issues by processing the text such that - we build word lists, separated by newlines, - we remember the original offsets for every word, and - after calling libxdiff on the wordlists, we parse the hunk headers, and find the corresponding offsets, and then - we print the removed/added parts in one go. The pre and post samples in the test were provided by Santi Béjar. Note that there is some strange special handling of hunk headers where one line range is 0 due to POSIX: in this case, the start is one too low. In other words a hunk header '@@ -1,0 +2 @@' actually means that the line must be added after the _second_ line of the pre text, _not_ the first.

For --inter-hunk-context=1, the resulting patch has the same number of lines but shows uninterrupted context instead of a context header line in between. Patches generated with this option are easier to read but are also more likely to conflict if the file to be patched contains other changes. This patch keeps the default for this option at 0. It is intended to just make the feature available in order to see its advantages and downsides.
