pre-push.sample: remove unnecessary and misleading IFS=' '

The sample hook explicitly sets IFS to SP and nothing else so that
the "read" used in the per-ref while loop that iterates over
"<localref> SP <localsha1> SP <remoteref> SP <remotesha>" records,
where we know refs and sha1s will not have SPs, would split them
correctly.

While this is not wrong per-se, it is not necessary; because we know
these fields do not contain HT or LF, either, we can simply leave
IFS the default.

This will also prevent those who cut and paste from this sample from
getting bitten when they write things in the per-ref loop that need
splitting with the default $IFS (e.g. use $(git rev-list ...) to
produce one-record-per-line output).

git-compat-util: suppress unavoidable Apple-specific deprecation warnings

With the release of Mac OS X 10.7 in July 2011, Apple deprecated all
openssl.h functionality due to OpenSSL ABI (application binary
interface) instability, resulting in an explosion of compilation
warnings about deprecated SSL, SHA1, and X509 functions (among others).

61067954ce (cache.h: eliminate SHA-1 deprecation warnings on Mac OS X;
2013-05-19) and be4c828b76 (imap-send: eliminate HMAC deprecation
warnings on Mac OS X; 2013-05-19) attempted to ameliorate the situation
by taking advantage of drop-in replacement functionality provided by
Apple's (ABI-stable) CommonCrypto facility, however CommonCrypto
supplies only a subset of deprecated OpenSSL functionality, thus a host
of warnings remain.

Despite this shortcoming, it was hoped that Apple would ultimately
provide CommonCrypto replacements for all deprecated OpenSSL
functionality, and that the effort started by 61067954ce and be4c828b76
would be continued and eventually eliminate all deprecation warnings.
However, now 3.5 years later, and with Mac OS X at 10.10, the hoped-for
CommonCrypto replacements have not yet materialized, nor is there any
indication that they will be forthcoming.

These Apple-specific warnings are pure noise: they don't tell us
anything useful and we have no control over them, nor is Apple likely to
provide replacements any time soon. Such noise may obscure other
legitimate warnings, therefore silence them.

fsck: complain about NTFS ".git" aliases in trees

Now that the index can block pathnames that can be mistaken
to mean ".git" on NTFS and FAT32, it would be helpful for
fsck to notice such problematic paths. This lets servers
which use receive.fsckObjects block them before the damage
spreads.

Note that the fsck check is always on, even for systems
without core.protectNTFS set. This is technically more
restrictive than we need to be, as a set of users on ext4
could happily use these odd filenames without caring about
NTFS.

However, on balance, it's helpful for all servers to block
these (because the paths can be used for mischief, and
servers which bother to fsck would want to stop the spread
whether they are on NTFS themselves or not), and hardly
anybody will be affected (because the blocked names are
variants of .git or git~1, meaning mischief is almost
certainly what the tree author had in mind).

Ideally these would be controlled by a separate
"fsck.protectNTFS" flag. However, it would be much nicer to
be able to enable/disable _any_ fsck flag individually, and
any scheme we choose should match such a system. Given the
likelihood of anybody using such a path in practice, it is
not unreasonable to wait until such a system materializes.

read-cache: optionally disallow NTFS .git variants

The point of disallowing ".git" in the index is that we
would never want to accidentally overwrite files in the
repository directory. But this means we need to respect the
filesystem's idea of when two paths are equal. The prior
commit added a helper to make such a comparison for NTFS
and FAT32; let's use it in verify_path().

We make this check optional for two reasons:

1. It restricts the set of allowable filenames, which is
unnecessary for people who are not on NTFS nor FAT32.
In practice this probably doesn't matter, though, as
the restricted names are rather obscure and almost
certainly would never come up in practice.

2. It has a minor performance penalty for every path we
insert into the index.

This patch ties the check to the core.protectNTFS config
option. Though this is expected to be most useful on Windows,
we allow it to be set everywhere, as NTFS may be mounted on
other platforms. The variable does default to on for Windows,
though.

path: add is_ntfs_dotgit() helper

We do not allow paths with a ".git" component to be added to
the index, as that would mean repository contents could
overwrite our repository files. However, asking "is this
path the same as .git" is not as simple as strcmp() on some
filesystems.

On NTFS (and FAT32), there exist so-called "short names" for
backwards-compatibility: 8.3 compliant names that refer to the same files
as their long names. As ".git" is not an 8.3 compliant name, a short name
is generated automatically, typically "git~1".

Depending on the Windows version, any combination of trailing spaces and
periods are ignored, too, so that both "git~1." and ".git." still refer
to the Git directory. The reason is that 8.3 stores file names shorter
than 8 characters with trailing spaces. So literally, it does not matter
for the short name whether it is padded with spaces or whether it is
shorter than 8 characters, it is considered to be the exact same.

The period is the separator between file name and file extension, and
again, an empty extension consists just of spaces in 8.3 format. So
technically, we would need only take care of the equivalent of this
regex:
(\.git {0,4}|git~1 {0,3})\. {0,3}

However, there are indications that at least some Windows versions might
be more lenient and accept arbitrary combinations of trailing spaces and
periods and strip them out. So we're playing it real safe here. Besides,
there can be little doubt about the intention behind using file names
matching even the more lenient pattern specified above, therefore we
should be fine with disallowing such patterns.

Extra care is taken to catch names such as '.\\.git\\booh' because the
backslash is marked as a directory separator only on Windows, and we want
to use this new helper function also in fsck on other platforms.

A big thank you goes to Ed Thomson and an unnamed Microsoft engineer for
the detailed analysis performed to come up with the corresponding fixes
for libgit2.

fsck: complain about HFS+ ".git" aliases in treesJeff King Mon, 15 Dec 2014 23:21:57 +0000 (18:21 -0500)

fsck: complain about HFS+ ".git" aliases in trees

Now that the index can block pathnames that case-fold to
".git" on HFS+, it would be helpful for fsck to notice such
problematic paths. This lets servers which use
receive.fsckObjects block them before the damage spreads.

Note that the fsck check is always on, even for systems
without core.protectHFS set. This is technically more
restrictive than we need to be, as a set of users on ext4
could happily use these odd filenames without caring about
HFS+.

However, on balance, it's helpful for all servers to block
these (because the paths can be used for mischief, and
servers which bother to fsck would want to stop the spread
whether they are on HFS+ themselves or not), and hardly
anybody will be affected (because the blocked names are
variants of .git with invisible Unicode code-points mixed
in, meaning mischief is almost certainly what the tree
author had in mind).

Ideally these would be controlled by a separate
"fsck.protectHFS" flag. However, it would be much nicer to
be able to enable/disable _any_ fsck flag individually, and
any scheme we choose should match such a system. Given the
likelihood of anybody using such a path in practice, it is
not unreasonable to wait until such a system materializes.

read-cache: optionally disallow HFS+ .git variantsJeff King Mon, 15 Dec 2014 23:15:20 +0000 (18:15 -0500)

read-cache: optionally disallow HFS+ .git variants

The point of disallowing ".git" in the index is that we
would never want to accidentally overwrite files in the
repository directory. But this means we need to respect the
filesystem's idea of when two paths are equal. The prior
commit added a helper to make such a comparison for HFS+;
let's use it in verify_path.

We make this check optional for two reasons:

1. It restricts the set of allowable filenames, which is
unnecessary for people who are not on HFS+. In practice
this probably doesn't matter, though, as the restricted
names are rather obscure and almost certainly would
never come up in practice.

2. It has a minor performance penalty for every path we
insert into the index.

This patch ties the check to the core.protectHFS config
option. Though this is expected to be most useful on OS X,
we allow it to be set everywhere, as HFS+ may be mounted on
other platforms. The variable does default to on for OS X,
though.

utf8: add is_hfs_dotgit() helper

We do not allow paths with a ".git" component to be added to
the index, as that would mean repository contents could
overwrite our repository files. However, asking "is this
path the same as .git" is not as simple as strcmp() on some
filesystems.

HFS+'s case-folding does more than just fold uppercase into
lowercase (which we already handle with strcasecmp). It may
also skip past certain "ignored" Unicode code points, so
that (for example) ".gi\u200ct" is mapped ot ".git".

The full list of folds can be found in the tables at:

https://www.opensource.apple.com/source/xnu/xnu-1504.15.3/bsd/hfs/hfscommon/Unicode/UCStringCompareData.h

Implementing a full "is this path the same as that path"
comparison would require us importing the whole set of
tables. However, what we want to do is much simpler: we
only care about checking ".git". We know that 'G' is the
only thing that folds to 'g', and so on, so we really only
need to deal with the set of ignored code points, which is
much smaller.

2. We check "." and ".." together, so it is possible that

add--interactive: leave main loop on read errorJeff King Mon, 15 Dec 2014 16:35:27 +0000 (11:35 -0500)

add--interactive: leave main loop on read error

The main hunk loop for add--interactive will loop if it does
not get a known input. This is a good thing if the user
typed some invalid input. However, if we have an
uncorrectable read error, we'll end up looping infinitely.
We can fix this by noticing read errors (i.e., <STDIN>
returns undef) and breaking out of the loop.

One easy way to trigger this is if you have an editor that
does not take over the terminal (e.g., one that spawns a
window in an existing process and waits), start the editor
with the hunk-edit command, and hit ^C to send SIGINT. The
editor process dies due to SIGINT, but the perl
add--interactive process does not (perl suspends SIGINT for
the duration of our system() call).

We return to the main loop, but further reads from stdin
don't work. The SIGINT _also_ killed our parent git process,
which orphans our process group, meaning that further reads
from the terminal will always fail. We loop infinitely,
getting EIO on each read.

Note that there are several other spots where we read from
stdin, too. However, in each of those cases, we do something
sane when the read returns undef (breaking out of the loop,
taking the input as "no", etc). They don't need similar
treatment.

commit: always populate GIT_AUTHOR_* variablesJeff King Wed, 10 Dec 2014 15:43:42 +0000 (10:43 -0500)

commit: always populate GIT_AUTHOR_* variables

To figure out the author ident for a commit, we call
determine_author_info(). This function collects information
from the environment, other commits (in the case of
"--amend" or "-c/-C"), and the "--author" option. It then
uses fmt_ident to generate the final ident string that goes
into the commit object. fmt_ident is therefore responsible
for any quality or validation checks on what is allowed to
go into a commit.

Before returning, though, we call split_ident_line on the
result, and feed the individual components to hooks via the
GIT_AUTHOR_* variables. Furthermore, we do extra validation
by feeding the split to sane_ident_split(), which is pickier
than fmt_ident (in particular, it will complain about an empty
email field). If this parsing or validation fails, we skip
updating the environment variables.

This is bad, because it means that hooks may silently see a
different ident than what we are putting into the commit. We
should drop the extra sane_ident_split checks entirely, and
take whatever fmt_ident has fed us (and what will go into
the commit object).

If parsing fails, we should actually abort here rather than
continuing (and feeding the hooks bogus data). However,
split_ident_line should never fail here. The ident was just
generated by fmt_ident, so we know that it's sane. We can
use assert_split_ident to double-check this.

Note that we also teach that assertion to check that we
found a date (it always should, but until now, no caller
cared whether we found a date or not). Checking the return
value of sane_ident_split is enough to ensure we have the
name/email pointers set, and checking date_begin is enough
to know that all of the date/tz variables are set.

commit: loosen ident checks when generating templateJeff King Wed, 10 Dec 2014 15:42:10 +0000 (10:42 -0500)

commit: loosen ident checks when generating template

When we generate the commit-message template, we try to
report an author or committer ident that will be of interest
to the user: an author that does not match the committer, or
a committer that was auto-configured.

When doing so, if we encounter what we consider to be a
bogus ident, we immediately die. This is a bad idea, because
our use of the idents here is purely informational. Any
ident rules should be enforced elsewhere, because commits
that do not invoke the editor will not even hit this code
path (e.g., "git commit -mfoo" would work, but "git commit"
would not). So at best, we are redundant with other checks,
and at worse, we actively prevent commits that should
otherwise be allowed.

We should therefore do the minimal parsing we can to get a
value and not do any validation (i.e., drop the call to
sane_ident_split()).

In theory we could notice when even our minimal parsing
fails to work, and do the sane thing for each check (e.g.,
if we have an author but can't parse the committer, assume
they are different and print the author). But we can
actually simplify this even further.

We know that the author and committer strings we are parsing
have been generated by us earlier in the program, and
therefore they must be parseable. We could just call
split_ident_line without even checking its return value,
knowing that it will put _something_ in the name/mail
fields. Of course, to protect ourselves against future
changes to the code, it makes sense to turn this into an
assert, so we are not surprised if our assumption fails.

t: support clang/gcc AddressSanitizerJeff King Mon, 8 Dec 2014 07:47:06 +0000 (02:47 -0500)

t: support clang/gcc AddressSanitizer

When git is compiled with "-fsanitize=address" (using clang
or gcc >= 4.8), all invocations of git will check for buffer
overflows. This is similar to running with valgrind, except
that it is more thorough (because of the compiler support,
function-local buffers can be checked, too) and runs much
faster (making it much less painful to run the whole test
suite with the checks turned on).

Unlike valgrind, the magic happens at compile-time, so we
don't need the same infrastructure in the test suite that we
did to support --valgrind. But there are two things we can
help with:

1. On some platforms, the leak-detector is on by default,
and causes every invocation of "git init" (and thus
every test script) to fail. Since running git with
the leak detector is pointless, let's shut it off
automatically in the tests, unless the user has already
configured it.

2. When apache runs a CGI, it clears the environment of
unknown variables. This means that the $ASAN_OPTIONS
config doesn't make it to git-http-backend, and it
dies due to the leak detector. Let's mark the variable
as OK for apache to pass.

With these two changes, running

make CC=clang CFLAGS=-fsanitize=address test

works out of the box.

update-ref: fix "verify" command with missing <oldvalue>Michael Haggerty Wed, 10 Dec 2014 23:47:52 +0000 (00:47 +0100)

update-ref: fix "verify" command with missing <oldvalue>

If "git update-ref --stdin" was given a "verify" command with no
"<newvalue>" at all (not even zeros), the code was mistakenly setting
have_old=0 (and leaving old_sha1 uninitialized). But this is
incorrect: this command is supposed to verify that the reference
doesn't exist. So in this case we really need old_sha1 to be set to
null_sha1 and have_old to be set to 1.

Moreover, since have_old was being set to zero, *no* check of the old
value was being done, so the new value of the reference was being set
unconditionally to the value in new_sha1. new_sha1, in turn, was set
to null_sha1 in the expectation that that was the old value and it
shouldn't be changed. But because the precondition was not being
checked, the result was that the reference was being deleted
unconditionally.

So, if <oldvalue> is missing, set have_old unconditionally and set
old_sha1 to null_sha1.

pkt-line: allow writing of LARGE_PACKET_MAX buffersJeff King Wed, 10 Dec 2014 09:47:02 +0000 (04:47 -0500)

pkt-line: allow writing of LARGE_PACKET_MAX buffers

When we send out pkt-lines with refnames, we use a static
1000-byte buffer. This means that the maximum size of a ref
over the git protocol is around 950 bytes (the exact size
depends on the protocol line being written, but figure on a sha1
plus some boilerplate).

This is enough for any sane workflow, but occasionally odd
things happen (e.g., a bug may create a ref "foo/foo/foo/..."
accidentally). With the current code, you cannot even use
"push" to delete such a ref from a remote.

Let's switch to using a strbuf, with a hard-limit of
LARGE_PACKET_MAX (which is specified by the protocol). This
matches the size of the readers, as of 74543a0 (pkt-line:
provide a LARGE_PACKET_MAX static buffer, 2013-02-20).
Versions of git older than that will complain about our
large packets, but it's really no worse than the current
behavior. Right now the sender barfs with "impossibly long
line" trying to send the packet, and afterwards the reader
will barf with "protocol error: bad line length %d", which
is arguably better anyway.

Note that we're not really _solving_ the problem here, but
just bumping the limits. In theory, the length of a ref is
unbounded, and pkt-line can only represent sizes up to
65531 bytes. So we are just bumping the limit, not removing
it. But hopefully 64K should be enough for anyone.

As a bonus, by using a strbuf for the formatting we can
eliminate an unnecessary copy in format_buf_write.

read_packed_refs: use skip_prefix instead of static array

We want to recognize the packed-refs header and skip to the
"traits" part of the line. We currently do it by feeding
sizeof() a static const array to strncmp. However, it's a
bit simpler to just skip_prefix, which expresses the
intention more directly, and without remembering to account
for the NUL-terminator in each sizeof() call.

read_packed_refs: use a strbuf for reading linesJeff King Wed, 10 Dec 2014 10:40:07 +0000 (05:40 -0500)

read_packed_refs: use a strbuf for reading lines

Current code uses a fixed PATH_MAX-sized buffer for reading
packed-refs lines. This is a reasonable guess, in the sense
that git generally cannot work with refs larger than
PATH_MAX. However, there are a few cases where it is not
great:

1. Some systems may have a low value of PATH_MAX, but can
actually handle larger paths in practice. Fixing this
code path probably isn't enough to make them work
completely with long refs, but it is a step in the
right direction.

2. We use fgets, which will happily give us half a line on
the first read, and then the rest of the line on the
second. This is probably OK in practice, because our
refline parser is careful enough to look for the
trailing newline on the first line. The second line may
look like a peeled line to us, but since "^" is illegal
in refnames, it is not likely to come up.

Still, it does not hurt to be more careful.

Make "-m -f" equivalent to "-M" and "-d -f" equivalent to" -D", i.e.
allow -f/--force to be used with -m/-d also.

For the list modes, "-f" is simply ignored.

parse_color: drop COLOR_BACKGROUND macro

Commit 695d95d (parse_color: refactor color storage,
2014-11-20) introduced two macros, COLOR_FOREGROUND and
COLOR_BACKGROUND. The latter conflicts with a system macro
defined on Windows, breaking compilation there.

The simplest solution is to just get rid of these macros
entirely. They are constants that are only used in one place
(since the whole point of 695d95d was to avoid repeating
ourselves). Their main function is to make the magic
character constants more readable, but we can do the same
thing with a comment.

doc: make clear --assume-unchanged's user contract

Many users misunderstand the --assume-unchanged contract, believing
it means Git won't look at the flagged file.

Be explicit that the --assume-unchanged contract is by the user that
they will NOT change the file so that Git does not need to look (and
expend, for example, lstat(2) cycles)

Mentioning "Git stops checking" does not help the reader, as it is
only one possible consequence of what that assumption allows Git to
do, but

(1) there are things other than "stop checking" that Git can do
based on that assumption; and
(2) Git is not obliged to stop checking; it merely is allowed to.

Also, this is a single flag bit, correct the plural to singular, and
the verb, accordingly.

Drop the stale and incorrect information about "poor-man's ignore",
which is not what this flag bit is about at all.

git-svn: support for git-svn propset

This change allows git-svn to support setting subversion properties.

It is useful for manually setting properties when committing to a
subversion repo that *requires* properties to be set without requiring
moving your changeset to separate subversion checkout in order to
set props.

This change is initially from David Fraser, appearing at:

http://mid.gmane.org/1927112650.1281253084529659.JavaMail.root@klofta.sjsoft.com>

They are now forward-ported to most recent git along with fixes to
deal with files in subdirectories.

Style and functional changes from Eric Wong have been taken
in their entirety from:

http://mid.gmane.org/20141201094911.GA13931@dcvr.yhbt.net

There is a nit to point out: the code does not support
adding props unless there are also content changes to the files as
well. This is demonstrated in the testcase.

[ew - simplify Git.pm usage for check-attr
- improve shell portability for tests
- minor phrasing changes in commit message]

test-hashmap: squelch gcc compiler warningJohannes Schindelin Tue, 9 Dec 2014 09:48:36 +0000 (10:48 +0100)

test-hashmap: squelch gcc compiler warning

At least on this developer's MacOSX (Snow Leopard, gcc-4.2.1), GCC
prints a warning that 'hash' may be used uninitialized when
compiling test-hashmap that 'hash' may be used uninitialized (but
GCC 4.6.3 on this developer's Ubuntu server does not report this
problem).

The old compiler is wrong, of course, as the switch (method & 3)
statement already handles all the possible cases, but that does not
help in a scenario where it is hard or impossible to upgrade to a
newer compiler (e.g. being stuck on an older MacOSX and having to
rely on Xcode).

So let's just initialize the variable and be done with it, it is
hardly a crucial part of the code because it is only used by the
test suite and invisible to the end users.

that only NUL-terminated buffers are passed around to begin with.

fsck: properly bound "invalid tag name" error messageJeff King Mon, 8 Dec 2014 05:48:13 +0000 (00:48 -0500)

fsck: properly bound "invalid tag name" error message

When we detect an invalid tag-name header in a tag object,
like, "tag foo bar\n", we feed the pointer starting at "foo
bar" to a printf "%s" formatter. This shows the name, as we
want, but then it keeps printing the rest of the tag buffer,
rather than stopping at the end of the line.

Our tests did not notice because they look only for the
matching line, but the bug is that we print much more than
we wanted to. So we also adjust the test to be more exact.

Note that when fscking tags with "index-pack --strict", this
is even worse. index-pack does not add a trailing
NUL-terminator after the object, so we may actually read
past the buffer and print uninitialized memory. Running
t5302 with valgrind does notice the bug for that reason.
