Merge branch 'jk/xdiff-interface'

2018-11-13T13:37:27Z

The interface into "xdiff" library used to discover the offset and size of a generated patch hunk by first formatting it into the textual hunk header "@@ -n,m +k,l @@" and then parsing the numbers out. A new interface has been introduced to allow callers a more direct access to them. * jk/xdiff-interface: xdiff-interface: drop parse_hunk_header() range-diff: use a hunk callback diff: convert --check to use a hunk callback combine-diff: use an xdiff hunk callback diff: use hunk callback for word-diff diff: discard hunk headers for patch-ids earlier diff: avoid generating unused hunk header lines xdiff-interface: provide a separate consume callback for hunks xdiff: provide a separate emit callback for hunks

combine-diff: use an xdiff hunk callback

2018-11-05T04:14:35Z

A combined diff has to line up the hunks for all of the individual pairwise diffs, and thus needs to know their line numbers and sizes. We get that now by parsing the hunk header line that xdiff generates. However, now that xdiff supports a hunk callback, we can just use the values directly.

xdiff-interface: provide a separate consume callback for hunks

2018-11-02T11:43:02Z

The previous commit taught xdiff to optionally provide the hunk header data to a specialized callback. But most users of xdiff actually use our more convenient xdi_diff_outf() helper, which ensures that our callbacks are always fed whole lines. Let's plumb the special hunk-callback through this interface, too. It will follow the same rule as xdiff when the hunk callback is NULL (i.e., continue to pass a stringified hunk header to the line callback). Since we add NULL to each caller, there should be no behavior change yet. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

convert "oidcmp() == 0" to oideq()

2018-08-29T18:32:49Z

Using the more restrictive oideq() should, in the long run, give the compiler more opportunities to optimize these callsites. For now, this conversion should be a complete noop with respect to the generated code. The result is also perhaps a little more readable, as it avoids the "zero is equal" idiom. Since it's so prevalent in C, I think seasoned programmers tend not to even notice it anymore, but it can sometimes make for awkward double negations (e.g., we can drop a few !!oidcmp() instances here). This patch was generated almost entirely by the included coccinelle patch. This mechanical conversion should be completely safe, because we check explicitly for cases where oidcmp() is compared to 0, which is what oideq() is doing under the hood. Note that we don't have to catch "!oidcmp()" separately; coccinelle's standard isomorphisms make sure the two are treated equivalently. I say "almost" because I did hand-edit the coccinelle output to fix up a few style violations (it mostly keeps the original formatting, but sometimes unwraps long lines).

object-store: move object access functions to object-store.h

2018-05-16T02:42:03Z

This should make these functions easier to find and cache.h less overwhelming to read. In particular, this moves: - read_object_file - oid_object_info - write_object_file As a result, most of the codebase needs to #include object-store.h. In this patch the #include is only added to files that would fail to compile otherwise. It would be better to #include wherever identifiers from the header are used. That can happen later when we have better tooling for it. Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano

sha1_file: convert read_sha1_file to struct object_id

2018-03-14T16:23:50Z

Convert read_sha1_file to take a pointer to struct object_id and rename it read_object_file. Do the same for read_sha1_file_extended. Convert one use in grep.c to use the new function without any other code change, since the pointer being passed is a void pointer that is already initialized with a pointer to struct object_id. Update the declaration and definitions of the modified functions, and apply the following semantic patch to convert the remaining callers: @@ expression E1, E2, E3; @@ - read_sha1_file(E1.hash, E2, E3) + read_object_file(&E1, E2, E3) @@ expression E1, E2, E3; @@ - read_sha1_file(E1->hash, E2, E3) + read_object_file(E1, E2, E3) @@ expression E1, E2, E3, E4; @@ - read_sha1_file_extended(E1.hash, E2, E3, E4) + read_object_file_extended(&E1, E2, E3, E4) @@ expression E1, E2, E3, E4; @@ - read_sha1_file_extended(E1->hash, E2, E3, E4) + read_object_file_extended(E1, E2, E3, E4) Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano
