When determining the file mode from either ls-tree or diff-tree

$git_perms .= "w" if ( $mode & 2 );
$git_perms .= "x" if ( $mode & 1 );
which was already wrong, as (100644 & 4) is very different from
oct("100644") & 4. An earlier refactoring 2c3af7e7 (cvsserver:

git-config: always treat --int as 64-bit internally
When you run "git config --int", the maximum size of integer
you get depends on how git was compiled, and what it
considers to be an "int".
This is almost useful, because your scripts calling "git
config" will behave similarly to git internally. But relying
on this is dubious; you have to actually know how git treats
each value internally (e.g., int versus unsigned long),
which is not documented and is subject to change. And even
if you know it is "unsigned long", we do not have a
git-config option to match that behavior.
Furthermore, you may simply be asking git to store a value
on your behalf (e.g., configuration for a hook). In that
case, the relevant range check has nothing at all to do with
git, but rather with whatever scripting tools you are using
(and git has no way of knowing what the appropriate range is
there).
Not only is the range check useless, but it is actively
harmful, as there is no way at all for scripts to look
at config variables with large values. For instance, one
cannot reliably get the value of pack.packSizeLimit via
git-config. On an LP64 system, git happily uses a 64-bit
"unsigned long" internally to represent the value, but the
script cannot read any value over 2G.
Ideally, the "--int" option would simply represent an
arbitrarily large integer. For practical purposes, however,
a 64-bit integer is large enough, and is much easier to
implement (and if somebody overflows it, we will still
notice the problem, and not simply return garbage).

If we try to parse an integer config argument and get a
number outside of the representable range, we die with the
cryptic message: "bad config value for '%s'".
We can improve two things:
1. Show the value that produced the error (e.g., bad
config value '3g' for 'foo.bar').
2. Mention the reason the value was rejected (e.g.,
"invalid unit" versus "out of range").
A few tests need to be updated with the new output, but that
should not be representative of real-world breakage, as
scripts should not be depending on the exact text of our
stderr output, which is subject to i18n anyway.

config: set errno in numeric git_parse_* functions
When we are parsing an integer or unsigned long, we use
the strto*max functions, which properly set errno to ERANGE
if we get a large value. However, we also do further range
checks after applying our multiplication factor, but do not
set ERANGE. This means that a caller cannot tell if an error
was caused by ERANGE or if the input was simply not a valid
number.
This patch teaches git_parse_signed and git_parse_unsigned to set
ERANGE for range errors, and EINVAL for other errors, so that the
caller can reliably tell these cases apart.
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
When we look at a config value as an integer using the
git_config_int function, we carefully range-check the value
we get and complain if it is out of our range. But the range
we compare to is that of a "long", which we then cast to an
"int" in the function's return value. This means that on
systems where "int" and "long" have different sizes (e.g.,
LP64 systems), we may pass the range check, but then return
nonsense by truncating the value as we cast it to an int.
We can solve this by converting git_parse_long into
git_parse_int, and range-checking the "int" range. Nobody
actually cared that we used a "long" internally, since the
result was truncated anyway. And the only other caller of
git_parse_long is git_config_maybe_bool, which should be
fine to just use int (though we will now forbid out-of-range
nonsense like setting "merge.ff" to "10g" to mean "true",
which is probably a good thing).

config: factor out integer parsing from range checks
When we are parsing integers for config, we use an intmax_t
(or uintmax_t) internally, and then check against the size
of our result type at the end. We can parameterize the
maximum representable value, which will let us re-use the
parsing code for a variety of range checks.
Unfortunately, we cannot combine the signed and unsigned
parsing functions easily, as we have to rely on the signed
and unsigned C types internally.

git_remote_helpers: remove little used Python library
When it was originally added, the git_remote_helpers library was used as
part of the tests of the remote-helper interface, but since commit fc407f9 (Add new simplified git-remote-testgit, 2012-11-28) a simple
shell script is used for this.
A search on Ohloh [1] indicates that this library isn't used by any
external projects and even the Python remote helpers in contrib/ don't
use this library, so it is only used by its own test suite.
Since this is the only Python library in Git, removing it will make
packaging easier as the Python scripts only need to be installed for one
version of Python, whereas the library should be installed for all
available versions.
One of the first things git-pull.sh does is setting $curr_branch to
the target of HEAD and $curr_branch_short to the same but with the
leading "refs/heads/" removed. Simplify the code by using
$curr_branch_short instead of setting $curr_branch to the same
shortened value.
The only other use of $curr_branch in that function doesn't have to
be replaced with $curr_branch_short because it just checks if the
string is empty. That property is the same with or without the prefix
unless HEAD points to "refs/heads/" alone, which is invalid.

Pass a list of open bzrlib.transport.Transport objects to each bzrlib
function that might create a transport. This enables bzrlib to reuse
existing transports when possible, avoiding multiple concurrent
connections to the same remote server.
If the remote server is accessed via ssh, this fixes a couple of
problems:
* If the user does not have keys loaded into an ssh agent, the user
may be prompted for a password multiple times.
* If the user is using OpenSSH and the ControlMaster setting is set
to auto, git-remote-bzr might hang. This is because bzrlib closes
the multiple ssh sessions in an undefined order and might try to
close the master ssh session before the other sessions. The
master ssh process will not exit until the other sessions have
exited, causing a deadlock. (The ssh sessions are closed in an
undefined order because bzrlib relies on the Python garbage
collector to trigger ssh session termination.)
