'git p4 rebase' fails with the following message if there is a file
named HEAD in the current directory:
fatal: ambiguous argument 'HEAD': both revision and filename
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
Take the suggestion above and explicitly state that HEAD should be
treated as a revision.

When "p4 where" fails, for whatever reason, the error message tries to
show an undefined variable. This minor bug applies only when using a
client spec, and was introduced recently in 9d57c4a (git p4: implement
view spec wildcards with "p4 where", 2013-08-30).

Commit 9d7d446 (git p4: submit files with wildcards, 2012-04-29)
fixed problems with handling files that had p4 wildcard
characters, like "@" and "*". But it missed one case, that of
RCS keyword scrubbing, which uses "p4 fstat" to extract type
information. Fix it by calling wildcard_encode() on the raw
filename.

Generating the submit template for p4 uses tempfile.mkstemp(),
which by default puts files in /tmp. For a test that fails,
possibly on purpose, this is not cleaned up. Run with TMPDIR
pointing into the trash directory so the temp files go away
with the test results.
To do this required some other minor changes. First, the editor
is launched using system(editor + " " + template_file), using
shell expansion to build the command string. This doesn't work
if editor has a space in it. And is generally unwise as it's
easy to fool the shell into doing extra work. Exec the args
directly, without shell expansion.
Second, without shell expansion, the trick of "P4EDITOR=:" used
in the tests doesn't work. Use a real command, true, as the
non-interactive editor for testing.

Damien Gérard highlights an interesting problem. Some p4
repositories end up with symlinks that have an empty target. It
is not possible to create this with current p4, but they do
indeed exist.
The effect in git p4 is that "p4 print" on the symlink returns an
empty string, confusing the curret symlink-handling code.
Such broken repositories cause problems in p4 as well, even with
no git involved. In p4, syncing to a change that includes a
bogus symlink causes errors:
//depot/empty-symlink - updating /home/me/p4/empty-symlink
rename: /home/me/p4/empty-symlink: No such file or directory
and leaves no symlink.
In git, replicate the p4 behavior by ignoring these bad symlinks.
If, in a later p4 revision, the symlink happens to point to
something non-null, the symlink will be replaced properly.
Add a big test for all this too.
This happens to be a regression introduced by 1292df1 (git-p4:
Fix occasional truncation of symlink contents., 2013-08-08) and
appeared first in 1.8.5. But it shows up only in p4 repositories
of dubious character, so can wait for a proper release.

git p4: implement view spec wildcards with "p4 where"
git p4 test: sanitize P4CHARSET
|
|
"git p4" does not support many of the view wildcards, such as * and
%%n. It only knows the common ... mapping, and exclusions.
Redo the entire wildcard code around the idea of directly querying
the p4 server for the mapping. For each commit, invoke "p4 where"
with committed file paths as args and use the client mapping to
decide where the file goes in git.
This simplifies a lot of code, and adds support for all wildcards
supported by p4. Downside is that there is probably a 20%-ish
slowdown with this approach.

The generic chdir() helper sets the PWD environment
variable, as that is what is used by p4 to know its
current working directory. Normally the shell would
do this, but in git-p4, we must do it by hand.
However, when the path contains a symbolic link,
os.getcwd() will return the physical location. If the
p4 client specification includes symlinks, setting PWD
to the physical location causes p4 to think it is not
inside the client workspace. It complains, e.g.
Path /vol/bar/projects/foo/... is not under client root /p/foo
One workaround is to use AltRoots in the p4 client specification,
but it is cleaner to handle it directly in git-p4.
Other uses of chdir still require setting PWD to an
absolute path so p4 features like P4CONFIG work. See
bf1d68f (git-p4: use absolute directory for PWD env
var, 2011-12-09).

On windows, p4 marks un-edited files as read-only. Not only are
they read-only, but also they cannot be deleted. Remove the
read-only attribute before deleting in both the copy and rename
cases.

to be deleted, but must first be edited to remove adjust the
keyword lines. Make sure it is editable before patching.

Files of type utf16 are handled with "p4 print" instead of the
normal "p4 -G print" interface due to how the latter does not
produce correct output. See 55aa571 (git-p4: handle utf16
filetype properly, 2011-09-17) for details.
On windows, though, "p4 print" can not be told which line
endings to use, as there is no underlying client, and always
chooses crlf, even for utf16 files. Convert the \r\n into \n
when importing utf16 files.
The fix for this is complex, in that the problem is a property
of the NT version of p4. There are old versions of p4 that
were compiled directly for cygwin that should not be subjected
to text replacement. The right check here, then, is to look
at the p4 version, not the OS version. Note also that on cygwin,
platform.system() is "CYGWIN_NT-5.1" or similar, not "Windows".
Add a function to memoize the p4 version string and use it to
check for "/NT", indicating the Windows build of p4.

Replacing \r\n with \n on windows was added in c1f9197 (Replace
\r\n with \n when importing from p4 on Windows, 2007-05-24), to
work around an oddity with "p4 print" on windows. Text files
are printed with "\r\r\n" endings, regardless of whether they
were created on unix or windows, and regardless of the client
LineEnd setting.
As of d2c6dd3 (use p4CmdList() to get file contents in Python
dicts. This is more robust., 2007-05-23), git-p4 uses "p4 -G
print", which generates files in a raw format. As the native
line ending format if p4 is \n, there will be no \r\n in the
raw text.
Actually, it is possible to generate a text file so that the
p4 representation includes embedded \r\n, even though this is not
normal on either windows or unix. In that case the code would
have mistakenly stripped them out, but now they will be left
intact.
More information on how p4 deals with line endings is here:

Commit fed2369 (git-p4: Search for parent commit on branch creation,
2012-01-25) uses temporary branches to help find the parent of a
new p4 branch. The temp branches are of the form "git-p4-tmp/%d"
for some p4 change number. Mistakenly, this string was made
using os.path.join() instead of just string concatenation. On
windows, this turns into a backslash (\), which is not allowed in
git branch names.

For a clone or sync, --branch says where the newly imported
branch should go, or which existing branch to sync up. It
takes an argument, which is currently either something that
starts with "refs/", or if not, "refs/heads/p4" is prepended.
Putting it in heads seems like a bad default; these should
go in remotes/p4/ in most situations. Make that the new default,
and be more liberal in the form of the branch name.

Error messages that arise during the "p4 print" phase of
generating commits were silently ignored. Catch them,
abort the fast-import, and exit.
Without this fix, the sync/clone appears to work, but files that

although without the proper contents. Instead the errant files
will contain a p4 error message, such as "Librarian checkout

But older versions of p4d may not handle the "-k" argument, and
newer p4d allow disabling "p4 move" with a configuration setting.
