12 years agothin-pack: try harder to use preferred base objects as base
Jeff King [Thu, 12 Jan 2012 22:32:34 +0000 (17:32 -0500)]
thin-pack: try harder to use preferred base objects as base

When creating a pack using objects that reside in existing packs, we try
to avoid recomputing futile delta between an object (trg) and a candidate
for its base object (src) if they are stored in the same packfile, and trg
is not recorded as a delta already. This heuristics makes sense because it
is likely that we tried to express trg as a delta based on src but it did
not produce a good delta when we created the existing pack.

As the pack heuristics prefer producing delta to remove data, and Linus's
law dictates that the size of a file grows over time, we tend to record
the newest version of the file as inflated, and older ones as delta
against it.

When creating a thin-pack to transfer recent history, it is likely that we
will try to send an object that is recorded in full, as it is newer.  But
the heuristics to avoid recomputing futile delta effectively forbids us
from attempting to express such an object as a delta based on another
object. Sending an object in full is often more expensive than sending a
suboptimal delta based on other objects, and it is even more so if we
could use an object we know the receiving end already has (i.e. preferred
base object) as the delta base.

Tweak the recomputation avoidance logic, so that we do not punt on
computing delta against a preferred base object.

The effect of this change can be seen on two simulated upload-pack
workloads. The first is based on 44 reflog entries from my git.git
origin/master reflog, and represents the packs that kernel.org sent me git
updates for the past month or two. The second workload represents much
larger fetches, going from git's v1.0.0 tag to v1.1.0, then v1.1.0 to
v1.2.0, and so on.

The table below shows the average generated pack size and the average CPU
time consumed for each dataset, both before and after the patch:

                  dataset
            | reflog | tags
---------------------------------
     before | 53358  | 2750977
size  after | 32398  | 2668479
     change |   -39% |      -3%
---------------------------------
     before |  0.18  | 1.12
CPU   after |  0.18  | 1.15
     change |    +0% |      +3%

This patch makes a much bigger difference for packs with a shorter slice
of history (since its effect is seen at the boundaries of the pack) though
it has some benefit even for larger packs.

12 years agoattr: don't confuse prefixes with leading directories
Jeff King [Tue, 10 Jan 2012 18:08:21 +0000 (13:08 -0500)]
attr: don't confuse prefixes with leading directories

When we prepare the attribute stack for a lookup on a path,
we start with the cached stack from the previous lookup
(because it is common to do several lookups in the same
directory hierarchy). So the first thing we must do in
preparing the stack is to pop any entries that point to
directories we are no longer interested in.

For example, if our stack contains gitattributes for:

  foo/bar/baz
  foo/bar
  foo

but we want to do a lookup in "foo/bar/bleep", then we want
to pop the top element, but retain the others.

To do this we walk down the stack from the top, popping
elements that do not match our lookup directory. However,
the test do this simply checked strncmp, meaning we would
mistake "foo/bar/baz" as a leading directory of
"foo/bar/baz_plus". We must also check that the character
after our match is '/', meaning we matched the whole path
component.

There are two special cases to consider:

  1. The top of our attr stack has the empty path. So we
     must not check for '/', but rather special-case the
     empty path, which always matches.

  2. Typically when matching paths in this way, you would
     also need to check for a full string match (i.e., the
     character after is '\0'). We don't need to do so in
     this case, though, because our path string is actually
     just the directory component of the path to a file
     (i.e., we know that it terminates with "/", because the
     filename comes after that).

The fixLinks() function adds 'js=1' to each link that does not already

that the browser can actually do javascript when these links are used.

There are two problems with the existing code:

  1. URIs with fragment and 'js' query parameter, like e.g.

        ...foo?js=0#l199

     were not recognized as having 'js' query parameter already.

  2. The 'js' query parameter, in the form of either '?js=1' or ';js=1'
     was appended at the end of URI, even if it included a fragment
     (had a hash part).  This lead to the incorrect links like this

        ...foo#l199?js=1

     instead of adding query parameter as last part of query, but
     before the fragment part, i.e.

git-read-tree.txt: update sparse checkout examples

The negation example uses '*' to match everything. This used to work
before 9037026 (unpack-trees: fix sparse checkout's "unable to match
directories") because back then, the list of paths is used to match
sparse patterns, so with the patterns

    *
    !subdir/

subdir/ always matches any path that start with subdir/ and "*" has no
chance to get tested. The result is subdir is excluded.

After the said commit, a tree structure is dynamically created and
sparse pattern matching now follows closely how read_directory()
applies .gitignore. This solves one problem, but reveals another one.

With this new strategy, "!subdir/" rule will be only tested once when
"subdir" directory is examined. Entries inside subdir, when examined,
will match "*" and are (correctly) re-added again because any rules
without a slash will match at every directory level. In the end, "*"
can revert every negation rules.

In order to correctly exclude subdir, we must use

    /*
    !subdir

to limit "match all" rule at top level only.

"*" rule has no actual use in sparse checkout and can be confusing to
users. While we can automatically turn "*" to "/*", this violates
.gitignore definition. Instead, discourage "*" in favor of "/*" (in
the second example).

If a file matches a pattern in sparse-checkout, then (it is to be
checked out and therefore) skip-worktree is unset for that file;
otherwise, it is set (so that it is not checked out).

Currently, the opposite is documented, and (consistently) read-tree's
behavior with respect to bit flips is descibed incorrectly.

Fix it.

In hindsight, it would have been much better to have a "sparse-ignore"
or "sparse-skip" file so that an empty file would mean a full checkout,
and the file logic would be analogous to that of .gitignore, excludes

fetch: skip on-demand checking when no submodules are configured

<new-ref-sha1> --not --all" in check_for_new_submodule_commits() when

Leave check_for_new_submodule_commits() early when no name <-> path

reading the configuration had to be moved further up in cmd_fetch(), as
doing that after the actual fetch of the superproject was too late.

clone: clone from a repository with relative alternates

Cloning from a local repository blindly copies or hardlinks all the files
under objects/ hierarchy. This results in two issues:

 - If the repository cloned has an "objects/info/alternates" file, and the
   command line of clone specifies --reference, the ones specified on the
   command line get overwritten by the copy from the original repository.

 - An entry in a "objects/info/alternates" file can specify the object
   stores it borrows objects from as a path relative to the "objects/"
   directory. When cloning a repository with such an alternates file, if
   the new repository is not sitting next to the original repository, such
   relative paths needs to be adjusted so that they can be used in the new
   repository.

This updates add_to_alternates_file() to take the path to the alternate
object store, including the "/objects" part at the end (earlier, it was
taking the path to $GIT_DIR and was adding "/objects" itself), as it is
technically possible to specify in objects/info/alternates file the path
of a directory whose name does not end with "/objects".
