Add pack-objects window memory usage limitBrian Downing Thu, 12 Jul 2007 13:07:46 +0000 (08:07 -0500)

Add pack-objects window memory usage limit

This adds an option (--window-memory=N) and configuration variable
(pack.windowMemory = N) to limit the memory size of the pack-objects
delta search window. This works by removing the oldest unpacked objects
whenever the total size goes above the limit. It will always leave
at least one object, though, so as not to completely eliminate the
possibility of computing deltas.

This is an extra limit on top of the normal window size (--window=N);
the window will not dynamically grow above the fixed number of entries
specified to fill the memory limit.

With this, repacking a repository with a mix of large and small objects
is possible even with a very large window.

Cleaner and correct circular buffer handling courtesy of Nicolas Pitre.

Support fetching the memory usage of a delta index

Delta indices, at least on 64-bit platforms, tend to be larger than
the actual uncompressed data. As such, keeping track of this storage
is important if you want to successfully limit the memory size of your
pack window.

Squirrel away the total allocation size inside the delta_index struct,
and add an accessor "sizeof_delta_index" to access it.

Don't try to delta if target is much smaller than sourceBrian Downing Thu, 12 Jul 2007 12:55:47 +0000 (07:55 -0500)

Don't try to delta if target is much smaller than source

Add a new try_delta heuristic. Don't bother trying to make a delta if
the target object size is much smaller (currently 1/32) than the source,
as it's very likely not going to get a match. Even if it does, you will
have to read at least 32x the size of the new file to reassemble it,
which isn't such a good deal. This leads to a considerable performance
improvement when deltifying a mix of small and large files with a very
large window, because you don't have to wait for the large files to
percolate out of the window before things start going fast again.

apply delta depth bias to already deltified objectsNicolas Pitre Thu, 12 Jul 2007 18:33:21 +0000 (14:33 -0400)

apply delta depth bias to already deltified objects

We already apply a bias on the initial delta attempt with max_size being
a function of the base object depth. This has the effect of favoring
shallower deltas even if deeper deltas could be smaller, and therefore
creating a wider delta tree (see commits 4e8da195 and c3b06a69).

This principle should also be applied to all delta attempts for the same
object and not only the first attempt. With this the criteria for the
best delta is not only its size but also its depth, so that a shallower
delta might be selected even if it is larger than a deeper one. Even if
some deltas get larger, they allow for wider delta trees making the
depth limit less quickly reached and therefore better deltas can be
subsequently found, keeping the resulting pack size even smaller.
Runtime access to the pack should also benefit from shallower deltas.

Testing on different repositories showed slighter faster repacks,
smaller resulting packs, and a much nicer curve for delta depth
distribution with no more peak at the maximum depth level.
Improvements are even more significant with smaller depth limits.

gitk: Improve handling of -- and ambiguous arguments

This makes gitk more consistent with git rev-list and git log in its
handling of arguments that could be either a revision or a filename;
now gitk displays an error message and quits, rather than treating it
as a revision and getting an error in the underlying git log. Now
gitk always passes "--" to git log even if no filenames are being
specified.

It also makes gitk display errors in invoking git log in a window
rather than on stderr, and makes gitk stop looking for a -d flag
when it sees a "--" argument.

Teach read-tree 2-way merge to ignore intermediate symlinks

Earlier in 16a4c61, we taught "read-tree -m -u" not to be
confused when switching from a branch that has a path frotz/filfre
to another branch that has a symlink frotz that points at xyzzy/
directory. The fix was incomplete in that it was still confused
when coming back (i.e. switching from a branch with frotz -> xyzzy/
to another branch with frotz/filfre).

This fix is rather expensive in that for a path that is created
we would need to see if any of the leading component of that
path exists as a symbolic link in the filesystem (in which case,
we know that path itself does not exist, and the fact we already
decided to check it out tells us that in the index we already
know that symbolic link is going away as there is no D/F
conflict).

This patch cleans up some complicated code, and replaces it with a
cleaner version, using code from remote.[ch], which got extended a
little in the process. This also enables us to fix two cases:

The earlier "fix" to setup tracking only when the original ref started
with "refs/remotes" is wrong. You are absolutely allowed to use a
separate layout for your tracking branches. The correct fix, of course,
is to set up tracking information only when there is a matching
remote.<nick>.fetch line containing a colon.

Another corner case was not handled properly. If two remotes write to
the original ref, just warn the user and do not set up tracking.

- It failed to replace git$X with git.o in the list of files that
record GIT_VERSION. This broke incorporation of a changed
GIT_VERSION into git$X because, when GIT_VERSION changes, git.o isn't

Support wholesale directory renames in fast-import

Some source material (e.g. Subversion dump files) perform directory
renames without telling us exactly which files in that subdirectory
were moved. This makes it hard for a frontend to convert such data
formats to a fast-import stream, as all the frontend has on hand
is "Rename a/ to b/" with no details about what files are in a/,
unless the frontend also kept track of all files.

The new 'R' subcommand within a commit allows the frontend to
rename either a file or an entire subdirectory, without needing to
know the object's SHA-1 or the specific files contained within it.
The rename is performed as efficiently as possible internally,
making it cheaper than a 'D'/'M' pair for a file rename.

big and `ls-tree -z` was generally fast enough that all data was ready

took a couple of pipe buffers for `ls-tree -z` to complete its dump.

gitk: Use git log and add support for --left-right

This is based on patches from Linus Torvalds and Junio Hamano, so the
ideas here are theirs.

This makes gitk use "git log -z --pretty=raw" instead of "git rev-list"
to generate the list of commits, and also makes it grok the "<" and ">"
markers that git log (and git rev-list) output with the --left-right
flag to indicate which side of a symmetric diff a commit is reachable
from. Left-side commits are drawn with a triangle pointing leftwards
instead of a circle, and right-side commits are drawn with a triangle
pointing rightwards. The commitlisted list is used to store the
left/right information as well as the information about whether each
commit is on the boundary.

git-gui: Perform our own magic shbang detection on Windows

If we cannot locate a .exe for a git tool that we want to run than
it may just be a Bourne shell script as these are popular in Git.
In such a case the first line of the file will say "#!/bin/sh" so
a UNIX kernel knows what program to start to parse and run that.
But Windows doesn't support shbang lines, and neither does the Tcl
that comes with Cygwin.

We can pass control off to the git wrapper as that is a real Cygwin
program and can therefore start the Bourne shell script, but that is
at least two fork+exec calls to get the program running. One to do
the fork+exec of the git wrapper and another to start the Bourne shell
script. If the program is run multiple times it is rather expensive
as the magic shbang detection won't be cached across executions.

On MinGW/MSYS we don't have the luxury of such magic detection. The
MSYS team has taught some of this magic to the git wrapper, but again
its slower than it needs to be as the git wrapper must still go and
run the Bourne shell after it is called.

We now attempt to guess the shbang line on Windows by reading the
first line of the file and building our own command line path from
it. Currently we support Bourne shell (sh), Perl and Python. That
is the entire set of shbang lines that appear in git.git today.

While I was working on this change I also converted all of our
existing pipes ([open "| git ..."]) to use two new pipe wrapper
functions. These functions take additional options like --nice
and --stderr which instructs Tcl to take special action, like
running the underlying git program through `nice` (if available)
or redirect stderr to stdout for capture in Tcl.

git-gui: Refactor branch switch to support detached head

This is a major rewrite of the way we perform switching between
branches and the subsequent update of the working directory. Like
core Git we now use a single code path to perform all changes: our
new checkout_op class. We also use it for branch creation/update
as it integrates the tracking branch fetch process along with a
very basic merge (fast-forward and reset only currently).

Because some users have literally hundreds of local branches we
use the standard revision picker (with its branch filtering tool)
to select the local branch, rather than keeping all of the local
branches in the Branch menu. The branch menu listing out all of
the available branches is simply not sane for those types of huge
repositories.

Users can now checkout a detached head by ticking off the option
in the checkout dialog. This option is off by default for the
obvious reason, but it can be easily enabled for any local branch
by simply checking it. We also detach the head if any non local
branch was selected, or if a revision expression was entered.

If you still want that "new" behavior, you can switch

with this message once we are done processing a block of work and
want the user to know we have completed it.

One of my production repositories has hundreds of remote tracking
branches. Trying to navigate these through a popup menu is just
not possible. The list is far larger than the screen and it does
not scroll fast enough to efficiently select a branch name when
trying to create a branch or delete a branch.

This is major rewrite of the revision chooser mega-widget. We
now use a single listbox for all three major types of named refs
(heads, tracking branches, tags) and a radio button group to pick
which of those namespaces should be shown in the listbox. A filter
field is shown to the right allowing the end-user to key in a glob
specification to filter the list they are viewing. The filter is
always taken as substring, so we assume * both starts and ends the
pattern the user wanted but otherwise treat it as a glob pattern.

This new picker works out really nicely. What used to take me at
least a minute to find and select a branch now takes mere seconds.

git-gui: Fast-forward existing branch in branch create dialog

If the user elects to create a local branch that has the same name
as an existing branch and we can fast-forward the local branch to
the selected revision we might as well do the fast-forward for the
user, rather than making them first switch to the branch then merge
the selected revision into it. After all, its really just a fast
forward. No history is lost. The resulting branch checkout may
also be faster if the branch we are switching from is closer to
the new revision.

Likewise we also now allow the user to reset the local branch if
it already exists but would not fast-forward. However before we
do the actual reset we tell the user what commits they are going to
lose by showing the oneline subject and abbreviated sha1, and we also
let them inspect the range of commits in gitk.

git-gui: Allow users to match remote branch names locally

Some workflows have users create a local branch that matches a remote
branch they have fetched from another repository. If the user wants
to push their changes back to that remote repository then they probably
want to use the same branch name locally so that git-gui's push dialog
can setup the push refspec automatically.

To prevent typos with the local branch name we now offer an option to
use the remote tracking branch name as the new local branch name.

git-gui: Maintain remote and source ref for tracking branches

In the next change I want to let the user create their local branch
name to match the remote branch name, so that the existing push
dialog can push the branch back up to the remote repository without
needing to do any sort of remapping. To do that we need to know
exactly what branch name the remote system is using.

So all_tracking_branches returns a list of specifications, where
each specification is itself a list of:

- local ref name (destination we fetch into)
- remote name (repository we fetch from)
- remote ref name (source ref we fetch from)

git-gui: Optimize for newstyle refs/remotes layoutShawn O. Pearce Wed, 4 Jul 2007 04:15:41 +0000 (00:15 -0400)

git-gui: Optimize for newstyle refs/remotes layout

Most people using Git 1.5.x and later are using the newer style
of remotes layout where all of their tracking branches are in
refs/remotes and refs/heads contains only the user's own local
branches.

In such a situation we can avoid calling is_tracking_branch
for each head we are considering because we know that all of
the heads must be local branches if no fetch option or Pull:
line maps a branch into that namespace.

If however any remote maps a remote branch into a local
tracking branch that resides in refs/heads we do exactly
what we did before, which requires scanning through all
fetch lines in case any patterns are matched.

I also switched some regexp/regsub calls to string match
as this can be a faster operation for prefix matching.

git-gui: Abstract the revision picker into a mega widget

This rather large change pulls the "Starting Revision" part of the
new branch dialog into a mega widget that we can use anytime we
need to select a commit SHA-1. To make use of the mega widget I
have also refactored the branch dialog to use the class system,
much like the delete remote branch dialog already does.

git-gui: Teach class system to support [$this cmd] syntax

Its handy to be able to ask an object to do something for you by
handing it a subcommand. For example if we want to get the value
of an object's private field the object could expose a method that
would return that value. Application level code can then invoke
"$inst get" to perform the method call.

Tk uses this pattern for all of its widgets, so we'd certainly
like to use it for our own mega-widgets that we might develop.
Up until now we haven't needed such functionality, but I'm working
on a new revision picker mega-widget that would benefit from it.

To make this work we have to change the definition of $this to
actually be a procedure within the namespace. By making $this a
procedure any caller that has $this can call subcommands by passing
them as the first argument to $this. That subcommand then needs
to call the proper subroutine.

Placing the dispatch procedure into the object's variable namespace
ensures that it will always be deleted when the object is deleted.

git-gui: Skip nicknames when selecting author initials

Our blame viewer only grabbed the first initial of the git.git
author string "Simon 'corecode' Schubert". Here the problem was we
looked at Simon, pulled the S into the author initials, then saw
the single quote as the start of the next name and did not like
this character as it was not an uppercase letter.

We now skip over single quoted nicknames placed within the author
name field and grab the initials following it. So the above name
will get the initials SS, rather than just S.

The blame window shows "who wrote the piece originally" and "who
moved it there" in two columns. In order to identify the former
more correctly, it helps to use the new -w option.

git-gui: New Git version check support routineShawn O. Pearce Sun, 8 Jul 2007 22:48:08 +0000 (18:48 -0400)

git-gui: New Git version check support routine

Some newer features of git-gui want to rely on features that are
new to Git 1.5.3. Since they were added as part of the 1.5.3
development series we cannot use those features with versions of
Git that are older than 1.5.3, such as from the stable 1.5.2 series.

We introduce [git-version >= 1.5.3] to allow the caller to get a
response of 0 if the current version of git is < 1.5.3 and 1 if
the current version of git is >= 1.5.3. This makes it easy to
setup conditional code based upon the version of Git available to
us at runtime.

Instead of parsing the version text by hand we now use the Tcl
[package vcompare] subcommand to compare the two version strings.
This works nicely, as Tcl as already done all of the hard work
of doing version comparsions. But we do have to remove the Git
specific components such as the Git commit SHA-1, commit count and
release candidate suffix (rc) as we want only the final release
version number.

user-manual: more explanation of push and pull usage

Recently a user on the mailing list complained that they'd read the
manual but couldn't figure out how to keep a couple private repositories
in sync. They'd tried using push, and were surprised by the effect.

Add a little text in an attempt to make it clear that:
- Pushing to a branch that is checked out will have odd results.
- It's OK to synchronize just using pull if that's simpler.
