combine-diff: refactor built-in xdiff interface. This refactors the line-by-line callback mechanism used in combine-diff so that other programs can reuse it more easily. Signed-off-by: Junio C Hamano <junkio@cox.net>

add xdi_diff_hunks() for callers that only need hunk lengths Based on a patch by Brian Downing, this uses the xdiff emit_func feature to implement xdi_diff_hunks(). It's a function that calls a callback for each hunk of a diff, passing its lengths. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>

xdl_diff: identify call sites. This inserts a new function xdi_diff() that currently does not do anything other than calling the underlying xdl_diff() to the callchain of current callers of xdl_diff() function. Signed-off-by: Junio C Hamano <gitster@pobox.com>

xdiff-interface: hide the whole "xdiff_emit_state" business from the caller This further enhances xdi_diff_outf() interface so that it takes two common parameters: the callback function that processes one line at a time, and a pointer to its application specific callback data structure. xdi_diff_outf() creates its own "xdiff_emit_state" structure and stashes these two away inside it, which is used by the lowest level output function in the xdiff_outf() callchain, consume_one(), to call back to the application layer. With this restructuring, we lift the requirement that the caller supplied callback data structure embeds xdiff_emit_state structure as its first member.

xdiff_emit_consume_fn fn, void *consume_callback_data,
remove ecb parameter from xdi_diff_outf() xdi_diff_outf() overrides the structure members of its last parameter, ignoring any value that callers pass in. It's no surprise then that all callers pass a pointer to an uninitialized structure. They also don't read it after the call, so the parameter is neither used for input nor for output. Turn it into a local variable of xdi_diff_outf(). Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Acked-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

userdiff: add xdiff_clear_find_func() 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.

Per-path attribute based hunk header selection. This makes"diff -p" hunk headers customizable via gitattributes mechanism. It is based on Johannes's earlier patch that allowed to define a single regexp to be used for everything. The mechanism to arrive at the regexp that is used to define hunk header is the same as other use of gitattributes. You assign an attribute, funcname (because "diff -p" typically uses the name of the function the patch is about as the hunk header), a simple string value. This can be one of the names of built-in pattern (currently, "java" is defined) or a custom pattern name, to be looked up from the configuration file. (in .gitattributes) *.java funcname=java *.perl funcname=perl (in .git/config) [funcname] java = ... # ugly and complicated regexp to override the built-in one. perl = ... # another ugly and complicated regexp to define a new one.
