always start looking up objects in the last used pack first
Jon Smirl said:
| Once an object reference hits a pack file it is very likely that
| following references will hit the same pack file. So first place to
| look for an object is the same place the previous object was found.
This is indeed a good heuristic so here it is. The search always start
with the pack where the last object lookup succeeded. If the wanted
object is not available there then the search continues with the normal
pack ordering.
To test this I split the Linux repository into 66 packs and performed a
"time git-rev-list --objects --all > /dev/null". Best results are as
follows:
Pack Sort w/o this patch w/ this patch
-------------------------------------------------------------
recent objects last 26.4s 20.9s
recent objects first 24.9s 18.4s
This shows that the pack order based on object age has some influence,
but that the last-used-pack heuristic is even more significant in
reducing object lookup.

Most of this is a hack. We try to determine if the path of our master

improve delta long block matching with big files
Martin Koegler noted that create_delta() performs a new hash lookup
after every block copy encoding which are currently limited to 64KB.
In case of larger identical blocks, the next hash lookup would normally
point to the next 64KB block in the reference buffer and multiple block
copy operations will be consecutively encoded.
It is however possible that the reference buffer be sparsely indexed if
hash buckets have been trimmed down in create_delta_index() when hashing
of the reference buffer isn't well balanced. In that case the hash
lookup following a block copy might fail to match anything and the fact
that the reference buffer still matches beyond the previous 64KB block
will be missed.
Let's rework the code so that buffer comparison isn't bounded to 64KB
anymore. The match size should be as large as possible up front and
only then should multiple block copy be encoded to cover it all.
Also, fewer hash lookups will be performed in the end.
According to Martin, this patch should reduce his 92MB pack down to 75MB
with the dataset he has.
Tests performed on the Linux kernel repo show a slightly smaller pack and
a slightly faster repack.

It is therefore common to be able to complete an entire operation
by accessing only one packfile, even if there are 25 packfiles
available to the repository.
Rather than opening and mmaping the corresponding .idx file for
every pack found, we now only open and map the .idx when we suspect
there might be an object of interest in there.
Of course we cannot known in advance which packfile contains an
object, so we still need to scan the entire packed_git list to
locate anything. But odds are users want to access objects in the
most recently created packfiles first, and that may be all they
ever need for the current operation.
Junio observed in
b867092f that placing recent packfiles before
older ones can slightly improve access times for recent objects,
without degrading it for historical object access.
This change improves upon Junio's observations by trying even harder
to avoid the .idx files that we won't need.

Make the pack-refs interfaces usable from outside
This just basically creates a "pack_refs()" function that could be used by
anybody. You pass it in the flags you want as a bitmask (PACK_REFS_ALL and
PACK_REFS_PRUNE), and it will do all the heavy lifting.
Of course, it's still static, and it's all in the builtin-pack-refs.c
file, so it's not actually visible to the outside, but the next step would
be to just move it all to a library file (probably refs.c) and expose it.
Then we could easily make "git gc" do this too.
While I did it, I also made it check the return value of the fflush and
fsync stage, to make sure that we don't overwrite the old packed-refs file
with something that got truncated due to write errors!

Fix mishandling of $Id$ expanded in the repository copy in convert.c
If the repository contained an expanded ident keyword (i.e. $Id:XXXX$),
then the wrong bytes were discarded, and the Id keyword was not
expanded. The fault was in convert.c:ident_to_worktree().
Previously, when a "$Id:" was found in the repository version,
ident_to_worktree() would search for the next "$" after this, and
discarded everything it found until then. That was done with the loop:
do {
ch = *cp++;
if (ch == '$')
break;
rem--;
} while (rem);
The above loop left cp pointing one character _after_ the final "$"
(because of ch = *cp++). This was different from the non-expanded case,
were cp is left pointing at the "$", and was different from the comment
which stated "discard up to but not including the closing $". This
patch fixes that by making the loop:
do {
ch = *cp;
if (ch == '$')
break;
cp++;
rem--;
} while (rem);
That is, cp is tested _then_ incremented.
This loop exits if it finds a "$" or if it runs out of bytes in the
source. After this loop, if there was no closing "$" the expansion is
skipped, and the outer loop is allowed to continue leaving this
non-keyword as it was. However, when the "$" is found, size is
corrected, before running the expansion:
size -= (cp - src);
This is wrong; size is going to be corrected anyway after the expansion,
so there is no need to do it here. This patch removes that redundant
correction.
To help find this bug, I heavily commented the routine; those comments
are included here as a bonus.

Make "git gc" pack all refs by default
I've taught myself to use "git gc" instead of doing the repack explicitly,
but it doesn't actually do what I think it should do.
We've had packed refs for a long time now, and I think it just makes sense
to pack normal branches too. So I end up having to do
git pack-refs --all --prune
in order to get a nice git repo that doesn't have any unnecessary files.
So why not just do that in "git gc"? It's not as if there really is any
downside to packing branches, even if they end up changing later. Quite
often they don't, and even if they do, so what?
Also, make the default for refs packing just be an unambiguous "do it",
rather than "do it by default only for non-bare repositories". If you want
that behaviour, you can always just add a
[gc]
packrefs = notbare
in your ~/.gitconfig file, but I don't actually see why bare would be any
different (except for the broken reason that http-fetching used to be
totally broken, and not doing it just meant that it didn't even get
fixed in a timely manner!).

name-rev: tolerate clock skew in committer dates
In git.git repository, "git-name-rev v1.3.0~158" cannot name the
rev, while adjacent revs can be named.
This was because it gives up traversal from the tips of existing
refs as soon as it sees a commit that has older commit timestamp
than what is being named. This is usually a good heuristics,
but v1.3.0~158 has a slightly older commit timestamp than
v1.3.0~157 (i.e. it's child), as these two were made in a
separate repostiory (in fact, in a different continent).
This adds a hardcoded slop value (1 day) to the cut-off
heuristics to work this kind of problem around. The current
algorithm essentially runs around from the available tips down
to ancient commits and names every single rev available that are
newer than cut-off date, so a single day slop would not add that
much overhead in repositories with long enough history where the
performance of name-rev matters.
I think the algorithm could be made a bit smarter by deepening
the graph on demand as a new commit is asked to be named (this
would require rewriting of name_rev() function not to recurse
itself but use a traversal list like revision.c traverser does),
but that would be a separate issue.
