12 years agoAvoid unnecessary 'lstat()' calls in 'get_stat_data()'
Linus Torvalds [Sat, 9 May 2009 21:57:30 +0000 (14:57 -0700)]
Avoid unnecessary 'lstat()' calls in 'get_stat_data()'

When we ask get_stat_data() to get the mode and size of an index entry,
we can avoid the lstat() call if we have marked the index entry as being
uptodate due to earlier lstat() calls.

This avoids a lot of unnecessary lstat() calls in eg 'git checkout',
where the last phase shows the differences to the working tree
(requiring a diff), but earlier phases have already verified the index.

On the kernel repo (with a fast machine and everything cached), this
changes timings of a nul 'git checkout' from

 - Before (best of ten):

0.14user 0.05system 0:00.19elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+13237minor)pagefaults 0swaps

 - After
0.11user 0.03system 0:00.15elapsed 98%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+13235minor)pagefaults 0swaps

so it can obviously be noticeable, although equally obviously it's not a
show-stopper on this particular machine. The difference is likely larger
on slower machines, or with operating systems that don't do as good a job
of name caching.

Ack, ack.

There's another easy 5% or so for the built-in object walker: once we've
created the hash from the name, the name isn't interesting any more, and
so something trivial like this can help a bit.

Does it matter? Probably not on its own. But a few more memory saving
tricks and it might all make a difference.

avoid possible overflow in delta size filtering computation

On a 32-bit system, the maximum possible size for an object is less than
4GB, while 64-bit systems may cope with larger objects.  Due to this
limitation, variables holding object sizes are using an unsigned long

When large objects are encountered, and/or people play with large delta
depth values, it is possible for the maximum allowed delta size
computation to overflow, especially on a 32-bit system.  When this
occurs, surviving result bits may represent a value much smaller than
what it is supposed to be, or even zero.  This prevents some objects
from being deltified although they do get deltified when a smaller depth

When the "bad" commit was also "skip"ped and when more than one
commit was skipped, the "filter_skipped" function would have
printed something like:

    bisect_rev=<hash1>|<hash2>

(where <hash1> and <hash2> are hexadecimal sha1 hashes)

and this would have been evaled later as piping "bisect_rev=<hash1>"
into "<hash2>", which would have failed.

So this patch makes the "filter_skipped" function properly quote
what it outputs, so that it will print something like:

bisect_rev='<hash1>|<hash2>'

which will be properly evaled later.  The caller was not stopping
properly because the scriptlet this function returned to be evaled
was not strung together with && and because of this, an error in
an earlier part of the output was simply ignored.

A test case is added to the test suite.

And while at it, we also initialize the VARS, FOUND and TRIED
variables, so that we protect ourselves from environment variables
the user may have with these names.

Make sure objects/pack exists before creating a new pack

In a repository created with git older than f49fb35 (git-init-db: create
"pack" subdirectory under objects, 2005-06-27), objects/pack/ directory is
not created upon initialization.  It was Ok because subdirectories are
created as needed inside directories init-db creates, and back then,
packfiles were recent invention.

After the said commit, new codepaths started relying on the presense of
objects/pack/ directory in the repository.  This was exacerbated with
8b4eb6b (Do not perform cross-directory renames when creating packs,
2008-09-22) that moved the location temporary pack files are created from
objects/ directory to objects/pack/ directory, because moving temporary to
the final location was done carefully with lazy leading directory creation.

Many packfile related operations in such an old repository can fail
mysteriously because of this.

This commit introduces two helper functions to make things work better.

 - odb_mkstemp() is a specialized version of mkstemp() to refactor the
   code and teach it to create leading directories as needed;

 - odb_pack_keep() refactors the code to create a ".keep" file while
