2015-07-04index-pack: fix allocation of sorted_by_pos arrayLibravatar Junio C Hamano1-8/+8
When c6458e60 (index-pack: kill union delta_base to save memory, 2015-04-18) attempted to reduce the memory footprint of index-pack, one of the key thing it did was to keep track of ref-deltas and ofs-deltas separately. In fix_unresolved_deltas(), however it forgot that it now wants to look only at ref deltas in one place. The code allocated an array for nr_unresolved, which is sum of number of ref- and ofs-deltas minus nr_resolved, which may be larger or smaller than the number ref-deltas. Depending on nr_resolved, this was either under or over allocating. Also, the old code before this change had to use 'i' and 'n' because some of the things we see in the (old) deltas[] array we scanned with 'i' would not make it into the sorted_by_pos[] array in the old world order, but now because you have only ref delta in a separate ref_deltas[] array, they increment lock&step. We no longer need separate variables. And most importantly, we shouldn't pass the nr_unresolved parameter, as this number does not play a role in the working of this helper function.

2015-07-01rev-list: disable --use-bitmap-index when pruning commitsLibravatar Jeff King1-1/+1
The reachability bitmaps do not have enough information to tell us which commits might have changed path "foo", so the current code produces wrong answers for: git rev-list --use-bitmap-index --count HEAD -- foo (it silently ignores the "foo" limiter). Instead, we should fall back to doing a normal traversal (it is OK to fall back rather than complain, because --use-bitmap-index is a pure optimization, and might not kick in for other reasons, such as there being no bitmaps in the repository).

2015-06-23Revert "diff-lib.c: adjust position of i-t-a entries in diff"Libravatar Junio C Hamano1-1/+0
This reverts commit d95d728aba06a34394d15466045cbdabdada58a2. It turns out that many other commands that need to interact with the result of running diff-files and diff-index, e.g. "git apply", "git rm", etc., need to be adjusted to the new world order it brings in. For example, it would break this sequence to correct a whitespace breakage in the parts you changed: git add -N file git diff --cached file | git apply --cached --whitespace=fix git checkout file In the old world order, "diff" showed a patch to modify an existing empty file by adding its full contents, and "apply" updated the index by modifying the existing empty blob (which is what an Intent-to-Add entry records in the index) with that patch. In the new world order, "diff" shows a patch to create a new file with its full contents, but because "apply" thinks that the i-t-a entry already exists in the index, it refused to accept a creation. Adjusting "apply" to this new world order is easy, but we need to assess the extent of the damage to the rest of the system the new world order brought in before going forward and adjust them all, after which we can resurrect the commit being reverted here.

2015-06-09index-pack: avoid excessive re-reading of pack directoryLibravatar Jeff King1-1/+1
Since 45e8a74 (has_sha1_file: re-check pack directory before giving up, 2013-08-30), we spend extra effort for has_sha1_file to give the right answer when somebody else is repacking. Usually this effort does not matter, because after finding that the object does not exist, the next step is usually to die(). However, some code paths make a large number of has_sha1_file checks which are _not_ expected to return 1. The collision test in index-pack.c is such a case. On a local system, this can cause a performance slowdown of around 5%. But on a system with high-latency system calls (like NFS), it can be much worse. This patch introduces a "quick" flag to has_sha1_file which callers can use when they would prefer high performance at the cost of false negatives during repacks. There may be other code paths that can use this, but the index-pack one is the most obviously critical, so we'll start with switching that one.

2015-06-04index-pack: fix truncation of off_t in comparisonLibravatar Jeff King1-2/+6
Commit c6458e6 (index-pack: kill union delta_base to save memory, 2015-04-18) refactored the comparison functions used in sorting and binary searching our delta list. The resulting code does something like: int cmp_offsets(off_t a, off_t b) { return a - b; } This works most of the time, but produces nonsensical results when the difference between the two offsets is larger than what can be stored in an "int". This can lead to unresolved deltas if the packsize is larger than 2G (even on 64-bit systems, an int is still typically 32 bits): $ git clone git://github.com/mozilla/gecko-dev Cloning into 'gecko-dev'... remote: Counting objects: 4800161, done. remote: Compressing objects: 100% (178/178), done. remote: Total 4800161 (delta 88), reused 0 (delta 0), pack-reused 4799978 Receiving objects: 100% (4800161/4800161), 2.21 GiB | 3.26 MiB/s, done.

2015-06-02for-each-ref: report broken references correctlyLibravatar Michael Haggerty1-0/+5
If there is a loose reference file with invalid contents, "git for-each-ref" incorrectly reports the problem as being a missing object with name NULL_SHA1: $ echo '12345678' >.git/refs/heads/nonsense $ git for-each-ref fatal: missing object 0000000000000000000000000000000000000000 for refs/heads/nonsense With an explicit "--format" string, it can even report that the reference validly points at NULL_SHA1: $ git for-each-ref --format='%(objectname) %(refname)' 0000000000000000000000000000000000000000 refs/heads/nonsense $ echo $? 0 This has been broken since b7dd2d2 for-each-ref: Do not lookup objects when they will not be used (2009-05-27) , which changed for-each-ref from using for_each_ref() to using git_for_each_rawref() in order to avoid looking up the referred-to objects unnecessarily. (When "git for-each-ref" is given a "--format" string that doesn't include information about the pointed-to object, it does not look up the object at all, which makes it considerably faster. Iterating with DO_FOR_EACH_INCLUDE_BROKEN is essential to this optimization because otherwise for_each_ref() would itself need to check whether the object exists as part of its brokenness test.) But for_each_rawref() includes broken references in the iteration, and "git for-each-ref" doesn't itself reject references with REF_ISBROKEN. The result is that broken references are processed *as if* they had the value NULL_SHA1, which is the value stored in entries for broken references. Change "git for-each-ref" to emit warnings for references that are REF_ISBROKEN but to otherwise skip them.

2015-06-01format-patch: do not feed tags to clear_commit_marks()Libravatar Junio C Hamano1-6/+6
"git format-patch --ignore-if-in-upstream A..B", when either A or B is a tag, failed miserably. This is because the code passes the tips it used for traversal to clear_commit_marks(), after running a temporary revision traversal to enumerate the commits on both branches to find if they have commits that make equivalent changes. The revision traversal machinery knows how to enumerate commits reachable starting from a tag, but clear_commit_marks() wants to take nothing but a commit. In the longer term, it might be a more correct fix to teach clear_commit_marks() to do the same "committish to commit" dereferencing that is done in the revision traversal machinery, but for now this fix should suffice.
