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.

I didn't have a chance to test the off-by-default minimize-url
stuff enough before, but it's quite broken for people passing
the --trunk/-T, --tags/-t, --branches/-b switches to "init" or
"clone" commands.
Additionally, follow-parent functionality seems broken when we're
not connected to the root of the repository.
Default behavior for "traditional" git-svn users who only track
one directory (without needing follow-parent) should be
reasonable, as those users started using things before
minimize-url functionality existed.
Behavior for users more used to the git-svnimport-like command
line will also benefit from a more-flexible command-line than
svnimport given the assumption they're working with
non-restrictive read permissions on the repository.
I hope to properly fix these bugs when I get a chance to in the
next week or so, but I would like to get this stopgap measure of
reverting to the old behavior as soon as possible.

When sorting directory names by depth (slash ("/") count) and
closing the deepest directories first (as the protocol
requires), we failed to put the root baton (with an empty string
as its key "") after top-level directories (which did not have
any slashes).
This resulted in svnserve being in a situation it couldn't

The todo list at the end of the user manual says that something must be
said about .gitignore. Also, there seems to be a lack of documentation
on how to choose between the various types of ignore files (.gitignore
vs. .git/info/exclude, etc.).
This patch adds a section on ignoring files which try to introduce how
to tell git about ignored files, and how the different strategies
complement eachother.
The syntax of exclude patterns is explained in a simplified manner, with
a reference to git-ls-files(1) which already contains a more thorough
explanation.

The embarassing history of this tutorial is that I started it without
really understanding the index well, so I avoided mentioning it.
And we all got the idea that "index" was a word to avoid using around
newbies, but it was reluctantly mentioned that *something* had to be
said. The result is a little awkward: the discussion of the index never
actually uses that word, and isn't well-integrated into the surrounding
material.
Let's just go ahead and use the word "index" from the very start, and
try to demonstrate its use with a minimum of lecturing.
Also, remove discussion of using git-commit with explicit filenames.
We're already a bit slow here to get people to their first commit, and
I'm not convinced this is really so important.

Helping a couple people set up public repos recently, I wanted to point
them at this piece of the user manual, but found it wasn't as helpful as
it could be:
- It starts with a big explanation of why you'd want a public
repository, not necessary in their case since they already knew
why they wanted that. So, separate that out.
- It skimps on some of the git-daemon details, and puts the http
export information first. Fix that.
Also group all the public repo subsections into a single section, and do
some miscellaneous related editing.

the "sharing development" chapter. While we're at it, remove some
discussion that's covered in earlier chapters, modernize somewhat (use
separate-heads setup, remotes, replace "whatchanged" by "log", etc.),
and replace syntax we'd need to explain by syntax we've already covered
(e.g. old..new instead of new ^old).

little. The manual might be a more visible location for some of them,

Revise and expand some of the definitions in the glossary, based in part
on a recent thread started by a user looking for help with some of the

thread. (I'm assuming standing permission to plagiarize Linus's
email....)
Also start making a few changes to mitigate the appearance of
"circularity" mentioned in that thread:
- feel free to use somewhat longer definitions and to explain
some things more than once instead of relying purely on
cross-references
- don't use cross-references when they're redundant: eliminate
self-references and repeated references to the same entry.

When using git name-rev on my kernel tree I triggered a malloc()
corruption warning from glibc.
apw@pinky$ git log --pretty=one $N/base.. | git name-rev --stdin
*** glibc detected *** malloc(): memory corruption: 0x0bff8950 ***
Aborted
This comes from name_rev() which is building the name of the revision
in a malloc'd string, which it sprintf's into:
char *new_name = xmalloc(len + 8);
[...]
sprintf(new_name, "%.*s~%d^%d", len, tip_name,
generation, parent_number);
This allocation is only sufficient if the generation number is
less than 5 digits, in my case generation was 13432. In reality
parent_number can be up to 16 so that also can require two digits,
reducing us to 3 digits before we are at risk of blowing this
allocation.
This patch introduces a decimal_length() which approximates the
number of digits a type may hold, it produces the following:
Type Longest Value Len Est
---- ------------- --- ---
unsigned char 256 3 4
unsigned short 65536 5 6
unsigned long 4294967296 10 11
unsigned long long 18446744073709551616 20 21
char -128 4 4
short -32768 6 6
long -2147483648 11 11
long long -9223372036854775808 20 21
