Jeff King	0508fe533d	combine-diff: respect textconv attributes When doing a combined diff, we did not respect textconv attributes at all. This generally lead to us printing "Binary files differ" when we could show a combined diff of the converted text. This patch converts file contents according to textconv attributes. The implementation is slightly ugly; because the textconv code is tightly linked with the diff_filespec code, we temporarily create a diff_filespec during conversion. In practice, though, this should not create a performance problem. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	14 years ago
Jeff King	4d5f347199	combine-diff: handle binary files as binary The combined diff code path is totally different from the regular diff code path, and didn't handle binary files at all. The results of a combined diff on a binary file could range from annoying (since we spewed binary garbage, possibly upsetting the user's terminal), to wrong (embedded NULs caused us to show incorrect diffs, with lines truncated at the NUL character), to potential security problems (embedded NULs could interfere with "-z" output, possibly defeating policy hooks which parse diff output). Instead, we consider a combined diff to be binary if any of the input blobs is binary. To show a binary combined diff, we indicate "Binary blobs differ"; the "index" meta line will show which parents had which blob.

combine-diff: respect textconv attributes

When doing a combined diff, we did not respect textconv attributes at
all. This generally lead to us printing "Binary files differ" when we
could show a combined diff of the converted text.

This patch converts file contents according to textconv attributes. The
implementation is slightly ugly; because the textconv code is tightly
linked with the diff_filespec code, we temporarily create a diff_filespec
during conversion. In practice, though, this should not create a
performance problem.

combine-diff: handle binary files as binary

The combined diff code path is totally different from the
regular diff code path, and didn't handle binary files at
all. The results of a combined diff on a binary file could
range from annoying (since we spewed binary garbage,
possibly upsetting the user's terminal), to wrong (embedded
NULs caused us to show incorrect diffs, with lines truncated
at the NUL character), to potential security problems
(embedded NULs could interfere with "-z" output, possibly
defeating policy hooks which parse diff output).

Instead, we consider a combined diff to be binary if any of
the input blobs is binary. To show a binary combined diff,
we indicate "Binary blobs differ"; the "index" meta line
will show which parents had which blob.
