* [PATCH 1/4] Add raw tree buffer info to "struct tree"
From: Linus Torvalds @ 2006-05-28 22:07 UTC (permalink / raw)
To: Junio C Hamano, Git Mailing List
In-Reply-To: <Pine.LNX.4.64.0605281453460.5623@g5.osdl.org>
This allows us to avoid allocating information for names etc, because
we can just use the information from the tree buffer directly.
We still keep the old "tree_entry_list" in struct tree as well, so old
users aren't affected, apart from the fact that the allocations are
different (if you free a tree entry, you should no longer free the name
allocation for it, since it's allocated as part of "tree->buffer")

* [PATCH 2/4] Make "tree_entry" have a SHA1 instead of a union of object pointers
From: Linus Torvalds @ 2006-05-28 22:10 UTC (permalink / raw)
To: Junio C Hamano, Git Mailing List
In-Reply-To: <Pine.LNX.4.64.0605281453460.5623@g5.osdl.org>
This is preparatory work for further cleanups, where we try to make
tree_entry look more like the more efficient tree-walk descriptor.
Instead of having a union of pointers to blob/tree/objects, this just
makes "struct tree_entry" have the raw SHA1, and makes all the users use
that instead (often that implies adding a "lookup_tree(..)" on the sha1,
but sometimes the user just wanted the SHA1 in the first place, and it
just avoids an unnecessary indirection).

* [PATCH 4/4] Remove "tree->entries" tree-entry list from tree parser
From: Linus Torvalds @ 2006-05-28 22:13 UTC (permalink / raw)
To: Junio C Hamano, Git Mailing List
In-Reply-To: <Pine.LNX.4.64.0605281453460.5623@g5.osdl.org>
This finally removes the tree-entry list from "struct tree", since most of
the users can just use the tree-walk infrastructure to walk the raw tree
buffers instead of the tree-entry list.
The tree-entry list is inefficient, and generates tons of small
allocations for no good reason. The tree-walk infrastructure is generally
no harder to use than following a linked list, and allows us to do most
tree parsing in-place.
Some programs still use the old tree-entry lists, and are a bit painful to
convert without major surgery. For them we have a helper function that
creates a temporary tree-entry list on demand. We can convert those too
eventually, but with this they no longer affect any users who don't need
the explicit lists.

Hi,
Dear diary, on Fri, May 26, 2006 at 05:28:37PM CEST, I got a letter
where Anand Kumria <wildfire@progsoc.uts.edu.au> said that...

hmm, might it be as simple as this?
---
This command makes Git read configuration from ~/.gitrc in addition
to the per-repository .git/config configuration file, and updates
the documentation accordingly (and also expands it a little).
Idea by Anand Kumria.

Well, if [alias] would be used also for giving default options for git
commands, e.g.
[alias]
log = log --pretty
(from what Petr "Pasky" Baudis said on IRC, currently on the right side
there should be only true git commands, which eliminates nicely problems
with recursion ;-), it would be better to ensure that aliases are checked
*only* for interactive sessions - otherwise using aliases for default
arguments would/could mess the scripts.

* Don't use "sscanf()" for tree mode scanning
From: Linus Torvalds @ 2006-05-28 23:16 UTC (permalink / raw)
To: Junio C Hamano, Git Mailing List
Doing an oprofile run on the result of my git rev-list memory leak fixes
and tree parsing cleanups, I was surprised by the third-highest entry
being
samples % image name app name symbol name
179751 2.7163 libc-2.4.so libc-2.4.so _IO_vfscanf@@GLIBC_2.4
where that 2.7% is actually more than 5% of one CPU, because this was run
on a dual CPU setup with the other CPU just being idle.
That seems to all be from the use of 'sscanf(tree, "%o", &mode)' for the
tree buffer parsing.
So do the trivial octal parsing by hand, which also gives us where the
first space in the string is (and thus where the pathname starts) so we
can get rid of the "strchr(tree, ' ')" call too.
This brings the "git rev-list --all --objects" time down from 63 seconds
to 55 seconds on the historical kernel archive for me, so it's quite
noticeable - tree parsing is a lot of what we end up doing when following
all the objects.
[ I also see a 5% speedup on a full "git fsck-objects" on the current
kernel archive, so that sscanf() really does seem to have hurt our
performance by a surprising amount ]

* [PATCH] git-send-email.perl extract_valid_address issue
From: Nicolas Troncoso Carrere @ 2006-05-29 4:00 UTC (permalink / raw)
To: git
The third fallback was returning if the match was done or not instead of
returning the actual email address that was matched. This prevented sending
the mail to the people included in the CC. This bug only affect those that
dont have Email::Valid.
I initialized $valid_email as undef so it would mimic the behavior of
Email::Verify->address(), which returns undef if no valid address was found.

A funny side effect of that would be that "git log" and "git-log" would
now have completely different defaults (unless the alias mechanism
starts intercepting direct calls to git-*, which seems invasive). I
wonder if it might be simpler to just add
core.defaults.log = "--pretty"
or similar.

Cool. Hmm... pdksh seems to support it here (Debian sid). I'm pretty
sure local is not part of the POSIX spec, though; and I have seen
/bin/sh that don't support it.

No problem. I think these dash bugs should be fixed in dash, but
continue to be worked around in git as old versions of dash will
probably continue to exist for a long time.

Concurred. There are things Herbert said are clearly dash bugs,

Actually, in properly installed git both versions should work,
and 'git command' is preferred version, at least for the ordinary
user level commands; "plumbing" commands are usually spelled 'git-command'.
Usually 'git command' is just a wrapper calling git-command.

Seth: how does this work?
Ick, I just found out keyword killing tests don't pass with
svn 1.1, though...

svn has trouble parsing files with embedded '@' characters. For
example,
svn propget svn:keywords foo@bar.c
svn: Syntax error parsing revision 'bar.c'
I asked about this on #svn and the workaround suggested was to append
an explicit revision specifier:
svn propget svn:keywords foo@bar.c@BASE
This patch appends '@BASE' to the filename in all calls to 'svn
propget'.

The essence of the thread: If you want to do anything useful in a non-bare
repository, you are likely using other tools than git, which do not
interpret core.umask or $GIT_DIR/umask.
If you use a bare repository, just make it shared. No need for an umask.
