| * t7810-*.sh: Remove redundant testRamsay Jones2012-07-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit bbc09c22 ("grep: rip out support for external grep", 12-01-2010), test number 60 ("grep -C1 hunk mark between files") is essentially the same as test number 59. Test 59 was intended to verify the behaviour of git-grep resulting from multiple invocations of an external grep. As part of the test, it creates and adds 1024 files to the index, which is now wasted effort. Remove test 59, since it is now redundant.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pfxlen can be longer than the path in objdir when relative_base contains the path to gits object directory. Here we are interested in checking if ent->base[] (the part that corresponds to .git/objects) is the same string as objdir, and the code NUL-terminated ent->base[] to LEADING PATH\0XX/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX\0 in preparation for these "duplicate check" step (before we return from the function, the first NUL is turned into '/' so that we can fill XX when probing for loose objects). All we need to do is to compare the string with the path to our object directory. Signed-off-by: Heiko Voigt <hvoigt@hvoigt.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * | Makefile: BLK_SHA1 does not require fast htonl() and unaligned loadsJonathan Nieder2012-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | block-sha1/ is fast on most known platforms. Clarify the Makefile to be less misleading about that. Early versions of block-sha1/ explicitly relied on fast htonl() and fast 32-bit loads with arbitrary alignment. Now it uses those on some arches but the default behavior is byte-at-a-time access for the sake of arches like ARM, Alpha, and their kin and it is still pretty fast on these arches (fast enough to supersede the mozilla SHA1 implementation and the hand-written ARM assembler implementation that were bundled before).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With 660231aa (block-sha1: support for architectures with memory alignment restrictions, 2009-08-12), blk_SHA1_Update was modified to access 32-bit chunks of memory one byte at a time on arches that prefer that: #define get_be32(p) ( \ (*((unsigned char *)(p) + 0) << 24) | \ (*((unsigned char *)(p) + 1) << 16) | \ (*((unsigned char *)(p) + 2) << 8) | \ (*((unsigned char *)(p) + 3) << 0) ) The code previously accessed these values by just using htonl(*p). Unfortunately, Michael noticed on an Alpha machine that git was using plain 32-bit reads anyway. As soon as we convert a pointer to int *, the compiler can assume that the object pointed to is correctly aligned as an int (C99 section 6.3.2.3 "pointer conversions" paragraph 7), and gcc takes full advantage by using a single 32-bit load, resulting in a whole bunch of unaligned access traps. So we need to obey the alignment constraints even when only dealing with pointers instead of actual values. Do so by changing the type of 'data' to void *. This patch renames 'data' to 'block' at the same time to make sure all references are updated to reflect the new type.

Prior to commit 468224e5, we did so by calling for_each_ref, and feeding each resulting refname to setup_revisions. Commit 468224e5 refactored this to simply mark the pending objects, saving an extra lookup. However, it confused the "flags" parameter to the each_ref_fn clalback, which is about the flags we found while looking up the ref with the object flag. Because REF_ISSYMREF ("this ref is a symbolic ref, e.g. refs/remotes/origin/HEAD") happens to be the same bit pattern as SEEN ("we have picked this object up from the pending list and moved it to revs.commits list"), we incorrectly reported that a commit previously at the detached HEAD will become unreachable if the only ref that can reach the commit happens to be pointed at by a symbolic ref.

The current order of precedence is: 1. gitattribute 2. GIT_EXTERNAL_DIFF 3. diff.external Usually our rule is that environment variables should take precedence over on-disk config (i.e., option 2 should come before option 1). However, this situation is trickier than some, because option 1 is more specific to the individual file than option 2 (which affects all files), so it might be preferable. So the current behavior can be seen as implementing "do the specific thing if we can, but fall back to this general thing". This is probably not what we would do if we were writing git from scratch, but it has been this way for several years, and is not worth changing. So let's at least document that this is the way it's supposed to work with a test. While we're there, let's also make sure that diff.external (which was not previously tested at all) works by running it through the same tests as GIT_EXTERNAL_DIFF.

This is because the logic to disable external diff was placed at a wrong level in the callchain. run_diff_cmd() decides to show the split patch only when external diff driver is not configured or specified via GIT_EXTERNAL_DIFF environment, but this is done before checking if --no-ext-diff was given. To make things worse, run_diff_cmd() checks --no-ext-diff and disables the output for such a filepair completely, as the callchain below it (e.g. builtin_diff) does not want to handle typechange filepairs.

Also introduce advice.amworkdir configuration to allow people who learned where to look to squelch this message.

This happens when module_clone() tries to find the relative paths between the work tree and the git dir. When a symbolic link in current $PWD points to a directory that is at a different level, then determining the number of "../" needed to traverse to the superproject's work tree leads to a wrong result. As there is no portable way to say "pwd -P", use cd_to_toplevel to remove the link from $PWD, which fixes this problem. A test for this issue has been added to t7406.
