Strictly speaking: no. The value doesn't matter -- the free(3) calls
above will be done with NULL regardless, due to the conditionals.
Setting bad_syn and good_syn to an invalid pointer would have calmed
the compiler just as well, and would have had no ill side effect (i.e.
no invalid free(3) call).
Initializing to NULL is still the correct thing to do, of course --
together with removing the conditionals (or at least the negations).
But back to the topic of why the compilers on OS X didn't optimize out
the free(3) calls with their conditionals. AFAICS no attributes are
set for the function in stdlib.h of in glibc[1] or Darwin[2]. And I
can't see any relevant option in config.mak.uname (e.g. -no-builtin).
It's not terribly important, but does anyone know what prevents the
elision of "if (!p) free(p);" on OS X?

I think this patch is probably correct in the current code, but I
say this only after following what quote_path_relative() and
relative_path() that is called from it. These warnings are preceded
by a call to a system library function, but it is not apparent that
they are immediately preceded without anything else that could have
failed in between.
Side note. There are many calls into strbuf API in these two
functions. Any calls to xmalloc() and friends made by strbuf
functions may see ENOMEM from underlying malloc() and recover by
releasing cached resources, by which time the original errno is
unrecoverable. So the above "probably correct" is not strictly
true.
If we care deeply enough that we want to reliably show the errno we
got from the preceding call to a system library function even after
whatever comes in between, I think you'd need the usual saved_errno
trick. Is that worth it?---I do not offhand have an opinion.

If you change the original definition of the "origin" to
[remote "origin"]
url = "c:\\repo\\"
fetch = +refs/heads/*:refs/remotes/origin/*
or
[remote "origin"]
url = c:\\repo\\ # ends with bs
fetch = +refs/heads/*:refs/remotes/origin/*
it seems to give me a better result. I didn't dig to determine
where things go wrong in "remote rename", and it is possible that
the problem is isolated to that command, or the same problem exists
with any value that ends with a backslash. If the latter, "git clone"
and anything that writes to configuration such a value needs to be
taught about this glitch and learn a workaround, I would think.

So, let's give Pranit a concrete "here is what we want to see
squashed in", while you guys discuss peculiarity with various
platforms and their system headers, which admittedly is a more
interesting tangent ;-)
There are early returns with "goto finish" even before _syn
variables are first assigned to, so they would need to be
initialized to NULL. The other two get their initial values
right at the beginning, so they are OK.

I wonder if xmalloc() should be the one doing the saved_errno trick.
After all, it has only two outcomes: we successfully allocated the
memory, or we called die().
And that would transitively make most of the strbuf calls errno-safe
(except for obvious syscall-related ones like strbuf_read_file). And in
turn that makes quote_path_relative() pretty safe (at least when writing
to a strbuf).

You are looking at builtin/log.c::make_cover_letter()? Patches
welcome, but I think you'd need a bit of preparatory refactoring
to allow gen_message_id() be called for all messages _before_ this
function is called, as currently we generate them as we emit each

Many people around here do not want to repeat the mistake of relying
too much on one provider. Listing Message-IDs may be a good idea,
listing URLs that are tied to one provider is less so.

Is it a --name-status, or is it your own custom format, that is
causing the above issue?
- What happens if you stop using --pretty=format:%h and replace it
with something like --oneline?
- What happens if you keep using --pretty=format:%h but replace
--name-status with something else, e.g. --raw or --stat?

Actually, I don't believe that is the case wrt decorations.
Why?
If you script the --oneline format and parse the output, you won't
have any decorations at all unless you are crazy (you can set
"log.decorations=true", but that will truly screw up any scripting).
And if you actually want decorations, and you're parsing them, you are
*not* going to script it with "--oneline --decorations", because the
end result is basically impossible to parse already (because it's
ambiguous - think about parentheses in the commit message).
So if you actually want decorations for parsing, you'd do something like
git log --pretty="%h '%D' %s"
which is at least parseable (because now the decoration separator is
unconditional.
Yeah, I guess you could use "--decorations --color=always" and then
use the color codes to parse the decorations, but that's so
complicated as to be unrealistic.
And I considered adding a format string explanation, something along
the lines of
- oneline used to mean "--pretty=%h%d %s", now it means "%h %s%d" instead
but that's actually not true. The "oneline" format was much more
complex than that, in that it has special rules for "-g", and it has
all those colorization ones too.

Thanks.
I need to ask an unrelated question at a bit higher level, though.
I have been operating under the assumption that everybody on Windows
who builds Git works off of Dscho's Git for Windows tree, and
patches that are specific to Windows from Dscho's are sent to me via
the list only after they have been in Git for Windows and proven to
help Windows users in the wild.
The consequence of these two assumptions is that I would feel safe
to treat Windows specific changes that do not touch generic part of
the codebase from Dscho just like updates from any other subsystem
maintainers (any git-svn thing from Eric, any gitk thing from Paul,
any p4 thing Luke and Lars are both happy with, etc.).
You seem to be saying that the first of the two assumptions does not
hold. Should I change my expectations while queuing Windows specific
patches from Dscho?

I didn't check the surrounding context to be sure, but I think this
"- to @{-1}" conversion cannot be delegated down to revision parsing
that eventually wants to return a 40-hex as the result.
We do want a branch _name_ sometimes when we say "@{-1}"; "checkout
master" (i.e. checkout by name) and "checkout master^0" (i.e. the
same commit object, but not by name) do different things.

I do not know about this one, but it smells like a branch name that
wants to be used before it gets turned into 40-hex.

FYI, the "@{-<number>} to branch name" translation happens in
interpret_branch_name(). I do not offhand recall if any callers
protect their calls to the function with conditionals that assume
the thing must begin with "@{" or cannot begin with "-" (the latter
of which is similar to the topic of patch 1/2 of this series), but I
suspect that teaching the function that "-" means the same as
"@{-1}" would bring us closer to where we want to go.

Yeah, I consider it a bug that we treat "-foo" as a message there.
Fortunately I think you really have to try hard to abuse it:
# doesn't work, because "save" complains about "-foo" as an option
git stash -foo
# does save stash with message "-foo"
git stash -- -foo
# doesn't work, because _any_ non-option argument is rejected
git stash -- use --foo option

Is it really that dangerous, though? The likely outcome is Git saying
"nope, you don't have any changes to the file named drop". Of course the
user may have meant something different, but I feel like "-p" is a good
indicator that they are interested in making an actual stash.
Think about this continuum of commands:
1. git stash droop
2. git stash -p drop
3. git stash -p -- drop
4. git stash push -p drop
I think we can all agree that (4) is reasonable and safe. And I suspect
we'd all agree that (1) is suspect (you probably meant "drop", not "push
droop").
But between (2) and (3), I don't see much difference. The interesting
difference between (1) and (2) is the addition of "-p", which tells us
that the user expects to save a stash.
Another way of thinking of it is that "-p" as a command name is an alias
for "push -p". If you wanted to err on the conservative side, you could
literally implement it that way (so "git stash -k -p foo" would not
work; you'd have to use "git stash -p -k foo").

The complexity is that right now, the first-level decision of "which
stash sub-command am I running?" doesn't know about any options. So "git
stash -m foo" would be rejected in the name of typo prevention, unless
that outer decision learns about "-m" as an option.

Why? I don't like adding forward declarations unless it
is absolutely necessary (ie mutually recursive functions),
and even in the current 'pu' branch (@c04899d50), the
definition of this function appears before all uses in
this file. (ie, just add static to the definition).
What am I missing?

Right. I view the removal of 'strip' as an accident when 'lstrip'

Good eyes. The fact that the two points at the same object means
that even if they were both annotated tags, they have the same
tagger dates.
If the code that compares the candidates and picks better tag to
describe the object with knows the refnames of these "tags", I'd
imagine that we could use the versioncmp() logic as the final tie
breaker, but I do not offhand remember if the original refname we
took the tag (or commit) from is propagated that deep down the
callchain. It probably does not, so some code refactoring may be
needed if somebody wants to go in that direction.

Each of these options is missing the closing single-quote on

It probably won't make too much difference, but the two code
sequences above are not similar in terms of side-effects when
'log' is false. In that case, the two calls to git_path() and
the call to rename() are not made in the original code. In the
new sequence, the two calls to strbuf_git_path() are always made
(but rename() is not).

I would be lying if I said I did not considered it when I wrote the
message you are responding to, but I rejected it because that would
be optimizing for a wrong case, in that most callers of xmalloc()
and friends do not do so in the error codepath, and we would be

I'm investigating now.
The warning text is being written to stderr and then main thread sleeps
for the 4 seconds.
However, stderr has been redirected to the pipe connected to the
console_thread that
handles the coloring/pager. It is in a blocking ReadFile on the pipe
and is thus stuck until
the main thread runs the corrected command and closes the pipe. It then
sees the EOF
and prints everything in the pipe buffer.
I'll look into fixing this now.
