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.
This also happens in the RCS cleanup code, where a file is marked
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,

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

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
are inaccessible by the p4d server will still be imported to git,
although without the proper contents. Instead the errant files
will contain a p4 error message, such as "Librarian checkout

Support for the "p4 move" command was added in 8e9497c (git p4:
add support for 'p4 move' in P4Submit, 2012-07-12), which checks
to make sure that the client and server support the command.
But older versions of p4d may not handle the "-k" argument, and
newer p4d allow disabling "p4 move" with a configuration setting.
Check for both these cases by testing a p4 move command on bogus
filenames and looking for strings in the error messages.

When editing the submit template, if no change was made to it,
git p4 offers a prompt "Submit anyway?". Answering "no" cancels
the submit.
Previously, a "no" answer behaves like a "[s]kip" answer to the
failed-patch prompt, in that it proceeded to try to apply the
rest of the commits. Instead, put users back into the new
"[s]kip / [c]ontinue" loop so that they can decide. This makes
both cases of patch failure behave identically.

as that for a "skip" due to failed patch; update a test to

When a patch failed to apply, these interactive options offered
to:
1) apply the patch anyway, leaving reject (.rej) files around, or,
2) write the patch to a file (patch.txt)
In both cases it suggested to invoke "git p4 submit --continue",
an unimplemented option.
While manually fixing the rejects and submitting the result might
work, there are many steps that must be done to the job properly:
* apply patch
* invoke p4 add and delete
* change executable bits
* p4 sync -f renamed/copied files
* extract commit message into p4 change description and
move Jobs lines out of description section
* set changelist owner for --preserve-user
Plus the following manual sync/rebase will cause conflicts too,
which must be resolved once again.
Drop these workflows. Instead users should do a sync/rebase in
git, fix the conflicts there, and do a clean "git p4 submit".

If a commit fails to apply cleanly to the p4 tree, an interactive
prompt asks what to do next. In all cases (skip, apply, write),
the behavior after the prompt had a few problems.
Change it so that it does not claim erroneously that all commits
were applied. Instead list the set of the patches under
consideration, and mark with an asterisk those that were
applied successfully. Like this example:
Applying 592f1f9 line5 in file1 will conflict
...
Unfortunately applying the change failed!
What do you want to do?
[s]kip this patch / [a]pply the patch forcibly and with .rej files / [w]rite the patch to a file (patch.txt) s
Skipping! Good luck with the next patches...
//depot/file1#4 - was edit, reverted
Applying b8db1c6 okay_commit_after_skip
...
Change 6 submitted.
Applied only the commits marked with '*':
592f1f9 line5 in file1 will conflict
* b8db1c6 okay_commit_after_skip
Do not try to sync and rebase unless all patches were applied.
If there was a conflict during the submit, there is sure to be one
at the rebase. Let the user to do the sync and rebase manually.
This changes how a couple tets in t9810-git-p4-rcs.sh behave:
- git p4 now does not leave files open and edited in the
client
- If a git commit contains a change to a file that was
deleted in p4, the test used to check that the sync/rebase
loop happened after the failure to apply the change. Since
now sync/rebase does not happen after failure, do not test
this. Normal rebase machinery, outside of git p4, will let
rebase --skip work.
