Pass empty file to p4merge where no base is suitable.Ciaran Jessup Sun, 1 May 2011 22:16:02 +0000 (23:16 +0100)

Pass empty file to p4merge where no base is suitable.

Modify the p4merge client command to pass a reference to an empty file
instead of the local file when no base revision available.

In the situation where a merge tries to add a file from one branch
into a branch that already contains that file (by name), p4merge
currently seems to have successfully automatically resolved the
'conflict' when it is opened (correctly if the files differed by
just whitespace for example) but leaves the save button disabled. This
means the user of the p4merge client cannot commit the resolved
changes back to disk and merely exits, leaving the original
(merge-conflicted) file intact on the disk.

Provide an empty base file to p4merge so that it leaves the save
button enabled. This will allow saving of the auto-resolution to
disk.

Look for password in both CVS and CVSNT password files.

In conn, if password is not passed on command line, look for a password
entry in both the CVS password file and the CVSNT password file. If only
one file is found and the requested repository is in that file, or if both
files are found but the requested repository is found in only one file, use
the password from the single file containing the repository entry. If both
files are found and the requested repository is found in both files, then
produce an error message.

The CVS password file separates tokens with a space character, while
the CVSNT password file separates tokens with an equal (=) character.
Add a sub find_password_entry that accepts the password file name
and a delimiter to eliminate code duplication.

merge-one-file: fix broken merges with alternate work... Jeff King Fri, 29 Apr 2011 22:24:32 +0000 (18:24 -0400)

merge-one-file: fix broken merges with alternate work trees

The merge-one-file tool predates the invention of
GIT_WORK_TREE. By the time GIT_WORK_TREE was invented, most
people were using the merge-recursive strategy, which
handles resolving internally. Therefore these features have
had very little testing together.

For the most part, merge-one-file just works with
GIT_WORK_TREE; most of its heavy lifting is done by plumbing
commands which do respect GIT_WORK_TREE properly. The one
exception is a shell redirection which touches the worktree
directly, writing results to the wrong place in the presence
of a GIT_WORK_TREE variable.

This means that merges won't even fail; they will silently
produce incorrect results, throwing out the entire "theirs"
side of files which need content-level merging!

This patch makes merge-one-file chdir to the toplevel of the
working tree (and exit if we don't have one). This most
closely matches the assumption made by the original script
(before separate work trees were invented), and matches what
happens when the script is called as part of a merge
strategy.

While we're at it, we'll also error-check the call to cat.
Merging a file in a subdirectory could in fact fail, as the
redirection relies on the "checkout-index" call just prior
to create leading directories. But we never noticed, since
we ignored the error return from running cat.

There were no tests for either, except a brief use in

These tools are not used much these days, as most people
use the merge-recursive strategy, which handles everything
internally. However, they are used by the "octopus" and
"resolve" strategies, as well as any custom strategies
or merge scripts people have built around them.

For example, together with read-tree, they are the simplest
way to do a basic content-level merge without checking out
the entire repository contents beforehand.

This script adds a basic test of the tools to perform one
content-level merge. It also shows a failure of the tools to
work properly in the face of GIT_WORK_TREE or core.worktree.

"add -p": work-around an old laziness that does not coalesce hunks

Since 0beee4c (git-add--interactive: remove hunk coalescing, 2008-07-02),
"git add--interactive" behaves lazily and passes overlapping hunks to the
underlying "git apply" without coalescing. This was partially corrected
by 7a26e65 (its partial revert, 2009-05-16), but overlapping hunks are
still passed when the patch is edited.

Teach "git apply" the --allow-overlap option that disables a safety
feature that avoids misapplication of patches by not applying patches
to overlapping hunks, and pass this option form "add -p" codepath.

Do not even advertise the option, as this is merely a workaround, and the
correct fix is to make "add -p" correctly coalesce adjacent patch hunks.

The names and e-mails are sanitized by fmt_ident() when creating commits,
so that they do not contain "<" nor ">", and the "committer" and "author"
lines in the commit object will always be in the form:

("author" | "committer") name SP "<" email ">" SP timestamp SP zone

When parsing the email part out, the current code looks for SP starting
from the end of the email part, but the author could obfuscate the address
as "author at example dot com".

We should instead look for SP followed by "<", to match the logic of the
side that formats these lines.

git-rebase--interactive.sh: preserve-merges fails on... Andrew Wong Thu, 28 Apr 2011 04:35:55 +0000 (00:35 -0400)

git-rebase--interactive.sh: preserve-merges fails on merges created with no-ff

'git rebase' uses 'git merge' to preserve merges (-p). This preserves
the original merge commit correctly, except when the original merge
commit was created by 'git merge --no-ff'. In this case, 'git rebase'
will fail to preserve the merge, because during 'git rebase', 'git
merge' will simply fast-forward and skip the commit. For example:

B
/ \
A---M
/
---o---O---P---Q

If we try to rebase M onto P, we lose the merge commit and this happens:

A---B
/
---o---O---P---Q

To correct this, we simply do a "no fast-forward" on all merge commits
when rebasing. Since by the time we decided to do a 'git merge' inside
'git rebase', it means there was a merge originally, so 'git merge'
should always create a merge commit regardless of what the merge
branches look like. This way, when rebase M onto P from the above
example, we get:

B
/ \
A---M
/
---o---O---P---Q

pretty: quote rfc822 specials in email addresses

If somebody has a name that includes an rfc822 special, we
will output it literally in the "From:" header. This is
usually OK, but certain characters (like ".") are supposed
to be enclosed in double-quotes in a mail header.

In practice, whether this matters may depend on your MUA.
Some MUAs will happily take in:

From: Foo B. Bar <author@example.com>

without quotes, and properly quote the "." when they send
the actual mail. Others may not, or may screw up harder
things like:

From: Foo "The Baz" Bar <author@example.com>

For example, mutt will strip the quotes, thinking they are
actual syntactic rfc822 quotes.

So let's quote properly, and then (if necessary) we still
apply rfc2047 encoding on top of that, which should make all
MUAs happy.

For projects that do not release official archives, gitweb's snapshot
feature would be an excellent alternative, and but without the '-n'
('--no-name') argument, gzip includes a timestamp in output which results
in different files. Because some systems hash/checksum downloaded files
to ensure integrity of the tarball (e.g FreeBSD), it is desirable to
produce tarballs in a reproducible way for that purpose.

Whilst '--no-name' is more descriptive, the long version of the flag is
not supported on all systems. In particular, OpenBSD does not appear to
support it.

Supply '-n' to gzip to exclude timestamp from output and produce idential
output every time.

send-pack: avoid deadlock when pack-object dies early

Send-pack deadlocks in two ways when pack-object dies early (for example,
because there is some repo corruption).

The first deadlock happens with the smart push protocol (--stateless-rpc).
After the initial rev-exchange, the remote is waiting for the pack data
to arrive, and the sideband demuxer at the local side continues trying to
stream data from the remote repository until it gets EOF. Meanwhile,
send-pack (in function pack_objects()) has noticed that pack-objects did
not produce output and died. Back in send_pack(), it now tries to clean
up the sideband demuxer using finish_async(). The demuxer, however, waits
for the remote end to close down, the remote waits for pack data, and
the reason that it still waits is that send-pack forgot to close the
outgoing channel. Add the missing close() in pack_objects().

The second deadlock happens in a similar constellation when the sideband
demuxer runs in a forked process (rather than in a thread). Again, the
remote end waits for pack data to arrive, the sideband demuxer waits for
the remote to shut down, and send-pack (in the regular clean-up) waits for
the demuxer to terminate. This time, the send-pack parent process closes
the writable end of the outgoing channel (in start_command() that spawned
pack-objects) so that after the death of the pack-objects process all
writable ends should have been closed and the remote repo should see EOF.
This does not happen, however, because when the sideband demuxer was forked
earlier, it also inherited a writable end; it remains open and keeps the
remote repo from seeing EOF. To break this deadlock, close the writable end
in the demuxer.

Fix "add -u" that sometimes fails to resolve unmerged... Junio C Hamano Thu, 21 Apr 2011 01:11:19 +0000 (18:11 -0700)

Fix "add -u" that sometimes fails to resolve unmerged paths

"git add -u" updates the index with the updated contents from the working
tree by internally running "diff-files" to grab the set of paths that are
different from the index. Then it updates the index entries for the paths
that are modified in the working tree, and deletes the index entries for
the paths that are deleted in the working tree.

It ignored the output from the diff-files that indicated that a path is
unmerged. For these paths, it instead relied on the fact that an unmerged
path is followed by the result of comparison between stage #2 (ours) and
the working tree, and used that to update or delete such a path when it is
used to record the resolution of a conflict.

As the result, when a path did not have stage #2 (e.g. "we deleted while
the other side added"), these unmerged stages were left behind, instead of
recording what the user resolved in the working tree.

Since we recently fixed "diff-files" to indicate if the corresponding path
exists on the working tree for an unmerged path, we do not have to rely on
the comparison with stage #2 anymore. We can instead tell the diff-files
not to compare with higher stages, and use the unmerged output to update
the index to reflect the state of the working tree.

The changes to the test vector in t2200 illustrates the nature of the bug
and the fix. The test expected stage #1 and #3 entries be left behind,
but it was codifying the buggy behaviour.

date: avoid "X years, 12 months" in relative dates

When relative dates are more than about a year ago, we start
writing them as "Y years, M months". At the point where we
calculate Y and M, we have the time delta specified as a
number of days. We calculate these integers as:

Y = days / 365
M = (days % 365 + 15) / 30

This rounds days in the latter half of a month up to the
nearest month, so that day 16 is "1 month" (or day 381 is "1
year, 1 month").

We don't round the year at all, though, meaning we can end
up with "1 year, 12 months", which is silly; it should just
be "2 years".

Implement this differently with months of size

onemonth = 365/12

so that

totalmonths = (long)( (days + onemonth/2)/onemonth )
years = totalmonths / 12
months = totalmonths % 12

In order to do this without floats, we write the first formula as

totalmonths = (days*12*2 + 365) / (365*2)

run-command: handle short writes and EINTR in die_child

If start_command fails after forking and before exec finishes, there
is not much use in noticing an I/O error on top of that.
finish_command will notice that the child exited with nonzero status
anyway. So as noted in v1.7.0.3~20^2 (run-command.c: fix build
warnings on Ubuntu, 2010-01-30) and v1.7.5-rc0~29^2 (2011-03-16), it
is safe to ignore errors from write in this codepath.

Even so, the result from write contains useful information: it tells
us if the write was cancelled by a signal (EINTR) or was only
partially completed (e.g., when writing to an almost-full pipe).
Let's use write_in_full to loop until the desired number of bytes have
been written (still ignoring errors if that fails).

As a happy side effect, the assignment to a dummy variable to appease
gcc -D_FORTIFY_SOURCE is no longer needed. xwrite and write_in_full
check the return value from write(2).

In git versions starting at v1.7.5-rc0~29^2 until v1.7.5-rc3~2 (Revert
"run-command: prettify -D_FORTIFY_SOURCE workaround", 2011-04-18)
fixed it, the run_command facility would write a truncated error
message when the command is present but cannot be executed for some
other reason. For example, if I add a 'hello' command to git:

$ echo 'echo hello' >git-hello
$ chmod +x git-hello
$ PATH=.:$PATH git hello
hello

and make it non-executable, this is what I normally get:

$ chmod -x git-hello
$ git hello
fatal: cannot exec 'git-hello': Permission denied

But with the problematic versions, we get disturbing output:

$ PATH=.:$PATH git hello
fatal: $

Add some tests to make sure it doesn't happen again.

The hello-script used in these tests uses cat instead of echo because
on Windows the bash spawned by git converts LF to CRLF in text written
by echo while the bash running tests does not, causing the test to
fail if "echo" is used. Thanks to Hannes for noticing.

Documentation: describe the format of messages with inline patches

Add a DISCUSSION section to the "git format-patch" manual to encourage
people to send patches in a form that can be applied by "git am"
automatically. There are two such forms:

1. The default form in which most metadata goes in the mail header
and the message body starts with the patch description;

2. The snipsnip form in which a message starts with pertinent
discussion and ends with a patch after a "scissors" mark.

The example requires QP encoding in the "Subject:" header intended for
the mailer to give the reader a chance to reflect on that, rather than
being startled by it later. By contrast, in-body "From:" and
"Subject:" lines should be human-readable and not QP encoded.

On systems where the local time and file modification time may be out of
sync (e.g. test directory on NFS) t3306 and t5305 can fail because prune
compares times such as "now" (client time) with file modification times
(server times for remote file systems). I.e., these are spurious test

Avoid this by setting the relevant modification times to the local time.

Noticed on a system with as little as 2s time skew.

mergetool: Teach about submodules

When the index has conflicted submodules, mergetool used to mildly
clobber the module, renaming it to mymodule.BACKUP.nnnn, then failing to
copy it non-recursively.

Recognize submodules and offer a resolution instead:

Submodule merge conflict for 'Shared':
{local}: submodule commit ad9f12e3e6205381bf2163a793d1e596a9e211d0
{remote}: submodule commit f5893fb70ec5646efcd9aa643c5136753ac89253
Use (l)ocal or (r)emote, or (a)bort?

Selecting a commit will stage it, but not update the submodule (as git
does had there been no conflict). Type changes are also supported,
should the path be a submodule on one side, and a file, symlink,
directory, or deleted on the other.

Teach --dirstat not to completely ignore rearranged... Johan Herland Sun, 10 Apr 2011 22:48:52 +0000 (00:48 +0200)

Teach --dirstat not to completely ignore rearranged lines within a file

Currently, the --dirstat analysis ignores when lines within a file are
rearranged, because the "damage" calculated by show_dirstat() is 0.
However, if the object name has changed, we already know that there is
some damage, and it is unintuitive to claim there is _no_ damage.

Teach show_dirstat() to assign a minimum amount of damage (== 1) to
entries for which the analysis otherwise yields zero damage, to still
represent that these files are changed, instead of saying that there
is no change.

Also, skip --dirstat analysis when the object names are the same (e.g. for
a pure file rename).

--dirstat-by-file: Make it faster and more correctJohan Herland Sun, 10 Apr 2011 22:48:51 +0000 (00:48 +0200)

--dirstat-by-file: Make it faster and more correct

Currently, when using --dirstat-by-file, it first does the full --dirstat
analysis (using diffcore_count_changes()), and then resets 'damage' to 1,
if any damage was found by diffcore_count_changes().

But --dirstat-by-file is not interested in the file damage per se. It only
cares if the file changed at all. In that sense it only cares if the blob
object for a file has changed. We therefore only need to compare the
object names of each file pair in the diff queue and we can skip the
entire --dirstat analysis and simply set 'damage' to 1 for each entry
where the object name has changed.

This makes --dirstat-by-file faster, and also bypasses --dirstat's practice
of ignoring rearranged lines within a file.

The patch also contains an added testcase verifying that --dirstat-by-file
now detects changes that only rearrange lines within a file.

git-svn: Add a svn-remote.<name>.pushurl config key

Similar to the 'remote.<name>.pushurl' config key for git remotes,
'pushurl' is designed to be used in cases where 'url' points to an SVN
repository via a read-only transport, to provide an alternate
read/write transport. It is assumed that both keys point to the same
repository.

The 'pushurl' key is distinct from the 'commiturl' key in that
'commiturl' is a full svn path while 'pushurl' (like 'url') is a base
path. 'commiturl' takes precendece over 'pushurl' in cases where
either might be used.

The 'pushurl' is used by git-svn's dcommit and branch commands.

One of these passes just fine; the other one exposes a problem where
command line flag order matters for --no-keep-index and --patch
interaction.

git-p4: replace each tab with 8 spaces for consistency

Note that the majority of git-p4 uses spaces, not tabs, for indentation.
Consistent indentation is a good hygiene for Python scripts, and mixing
tabs and spaces in Python can lead to hard-to-find bugs.

It may be better to rename the "driver" in "diff.<driver>.*" to
something like "content type" or "file type", but for now, let's keep
it consistent across this part of the documentation and the original

upload-pack: start pack-objects before async rev-listJeff King Wed, 6 Apr 2011 21:33:33 +0000 (17:33 -0400)

upload-pack: start pack-objects before async rev-list

In a pthread-enabled version of upload-pack, there's a race condition
that can cause a deadlock on the fflush(NULL) we call from run-command.

What happens is this:

1. Upload-pack is informed we are doing a shallow clone.

2. We call start_async() to spawn a thread that will generate rev-list
results to feed to pack-objects. It gets a file descriptor to a
pipe which will eventually hook to pack-objects.

3. The rev-list thread uses fdopen to create a new output stream
around the fd we gave it, called pack_pipe.

4. The thread writes results to pack_pipe. Outside of our control,
libc is doing locking on the stream. We keep writing until the OS
pipe buffer is full, and then we block in write(), still holding
the lock.

5. The main thread now uses start_command to spawn pack-objects.
Before forking, it calls fflush(NULL) to flush every stdio output
buffer. It blocks trying to get the lock on pack_pipe.

And we have a deadlock. The thread will block until somebody starts
reading from the pipe. But nobody will read from the pipe until we
finish flushing to the pipe.

To fix this, we swap the start order: we start the
pack-objects reader first, and then the rev-list writer
after. Thus the problematic fflush(NULL) happens before we
even open the new file descriptor (and even if it didn't,
flushing should no longer block, as the reader at the end of
the pipe is now active).

stash: drop dirty worktree check on applyJeff King Tue, 5 Apr 2011 21:23:15 +0000 (17:23 -0400)

stash: drop dirty worktree check on apply

Before we apply a stash, we make sure there are no changes
in the worktree that are not in the index. This check dates
back to the original git-stash.sh, and is presumably
intended to prevent changes in the working tree from being
accidentally lost during the merge.

However, this check has two problems:

1. It is overly restrictive. If my stash changes only file
"foo", but "bar" is dirty in the working tree, it will
prevent us from applying the stash.

2. It is redundant. We don't touch the working tree at all
until we actually call merge-recursive. But it has its
own (much more accurate) checks to avoid losing working
tree data, and will abort the merge with a nicer
message telling us which paths were problems.

So we can simply drop the check entirely.

stash: fix false positive in the invalid ref test.

Jeff King reported a problem with git stash apply incorrectly
applying an invalid stash reference.

There is an existing test that should have caught this, but
the test itself was broken, resulting in a false positive.

stash: fix accidental apply of non-existent stashesJeff King Tue, 5 Apr 2011 21:20:25 +0000 (17:20 -0400)

stash: fix accidental apply of non-existent stashes

Once upon a time, "git rev-parse ref@{9999999}" did not
generate an error. Therefore when we got an invalid stash
reference in "stash apply", we could end up not noticing
until quite late. Commit b0f0ecd (detached-stash: work
around git rev-parse failure to detect bad log refs,
2010-08-21) handled this by checking for the "Log for stash
has only %d entries" warning on stderr when we validated the
ref.

A few days later, e6eedc3 (rev-parse: exit with non-zero
status if ref@{n} is not valid., 2010-08-24) fixed the
original issue. That made the extra stderr test superfluous,
but also introduced a new bug. Now the early call to:

git rev-parse --symbolic "$@"

fails, but we don't notice the exit code. Worse, its empty
output means we think the user didn't provide us a ref, and
we try to apply stash@{0}.

This patch checks the rev-parse exit code and fails early in
the revision parsing process. We can also get rid of the
stderr test; as a bonus, this means that "stash apply" can
now run under GIT_TRACE=1 properly.
