The command line to invoke a "git cat-file" command from inside
"git p4" was not properly quoted to protect a caret and running a
broken command on Windows, which has been corrected.
* mm/p4-unshelve-windows-fix:
p4 unshelve: fix "Not a valid object name HEAD0" on Windows
git p4 unshelve was failing with these errors:
fatal: Not a valid object name HEAD0
Command failed: git cat-file commit HEAD^0
(git version 2.21.0.windows.1, python 2.7.16)
The pOpen call used by git-p4 to invoke the git command can take either a
string or an array as a first argument. The array form is preferred
because platform-specific escaping of special characters will be
handled automatically.(https://docs.python.org/2/library/subprocess.html)
The extractLogMessageFromGitCommit method was, however, using the string
form and so the caret (^) character in the HEAD^0 argument was not being
escaped on Windows. The caret happens to be the escape character, which
is why the git command was receiving HEAD0.
The behaviour can be confirmed by typing ECHO HEAD^0 at the command-
prompt, which emits HEAD0.
The solution is simply to use the array format of passing the command to
fOpen, which is recommended and used in other parts of this code anyway.

When unshelving a changelist, git-p4 tries to work out the appropriate
parent commit in a given branch (default: HEAD). To do this, it looks
at the state of any pre-existing files in the target Perforce branch,
omitting files added in the shelved changelist. Currently, only files
added (or move targets) are classed as new. However, files integrated
from other branches (i.e. a 'branch' action) also need to be considered
as added, for this purpose.

The previous git-p4 unshelve support would check for changes
in Perforce to the files being unshelved since the original
shelve, and would complain if any were found.
This was to ensure that the user wouldn't end up with both the
shelved change delta, and some deltas from other changes in their
git commit.
e.g. given fileA:
the
quick
brown
fox
change1: s/the/The/ <- p4 shelve this change
change2: s/fox/Fox/ <- p4 submit this change
git p4 unshelve 1 <- FAIL
This change teaches the P4Unshelve class to always create a parent
commit which matches the P4 tree (for the files being unshelved) at
the point prior to the P4 shelve being created (which is reported
in the p4 description for a shelved changelist).
That then means git-p4 can always create a git commit matching the
P4 shelve that was originally created, without any extra deltas.
The user might still need to use the --origin option though - there
is no way for git-p4 to work out the versions of all of the other
*unchanged* files in the shelve, since this information is not recorded
by Perforce.
Additionally this fixes handling of shelved 'move' operations.

"git p4" updates.
* ld/git-p4-updates:
git-p4: auto-size the block
git-p4: narrow the scope of exceptions caught when parsing an int
git-p4: raise exceptions from p4CmdList based on error from p4 server
git-p4: better error reporting when p4 fails
git-p4: add option to disable syncing of p4/master with p4
git-p4: disable-rebase: allow setting this via configuration
git-p4: add options --commit and --disable-rebase
git-p4 originally would fetch changes in one query. On large repos this
could fail because of the limits that Perforce imposes on the number of
items returned and the number of queries in the database.
To fix this, git-p4 learned to query changes in blocks of 512 changes,
However, this can be very slow - if you have a few million changes,
with each chunk taking about a second, it can be an hour or so.
Although it's possible to tune this value manually with the
"--changes-block-size" option, it's far from obvious to ordinary users
that this is what needs doing.
This change alters the block size dynamically by looking for the
specific error messages returned from the Perforce server, and reducing
the block size if the error is seen, either to the limit reported by the
server, or to half the current block size.
That means we can start out with a very large block size, and then let
it automatically drop down to a value that works without error, while
still failing correctly if some other error occurs.

This change lays some groundwork for better handling of rowcount errors
from the server, where it fails to send us results because we requested
too many.
It adds an option to p4CmdList() to return errors as a Python exception.
The exceptions are derived from P4Exception (something went wrong),
P4ServerException (the server sent us an error code) and
P4RequestSizeException (we requested too many rows/results from the
server database).
This makes the code that handles the errors a bit easier.

This can be used to "unshelve" a shelved P4 commit into
a git commit.
For example:
$ git p4 unshelve 12345
The resulting commit ends up in the branch:
refs/remotes/p4/unshelved/12345
If that branch already exists, it is renamed - for example
the above branch would be saved as p4/unshelved/12345.1.
git-p4 checks that the shelved changelist is based on files
which are at the same Perforce revision as the origin branch
being used for the unshelve (HEAD by default). If they are not,
it will refuse to unshelve. This is to ensure that the unshelved
change does not contain other changes mixed-in.
The reference branch can be changed manually with the "--origin"
option.
The change adds a new Unshelve command class. This just runs the
existing P4Sync code tweaked to handle a shelved changelist.

* ls/p4-path-encoding:
git-p4: fix git-p4.pathEncoding for removed files
In a9e38359e3 we taught git-p4 a way to re-encode path names from what
was used in Perforce to UTF-8. This path re-encoding worked properly for
"added" paths. "Removed" paths were not re-encoded and therefore
different from the "added" paths. Consequently, these files were not
removed in a git-p4 cloned Git repository because the path names did not
match.
Fix this by moving the re-encoding to a place that affects "added" and
"removed" paths. Add a test to demonstrate the issue.

When running git-p4 on Windows, with multiple git-p4.mapUser entries in
git config - no user mappings are applied to the generated repository.
Reproduction Steps:
1. Add multiple git-p4.mapUser entries to git config on a Windows
machine
2. Attempt to clone a p4 repository
None of the user mappings will be applied.
This issue is actually caused by gitConfigList, using split(os.linesep)
to convert the output of git config --get-all into a list. On Windows,
os.linesep is equal to '\r\n' - however git.exe returns configuration
with a line seperator of '\n'.
This leads to the list returned by gitConfigList containing only one
element - which contains the full output of git config --get-all in
string form, which causes problems for the code introduced to
getUserMapFromPerforceServer in 10d08a149d ("git-p4: map a P4 user to

typical delimiters ('\n', '\r\n' etc.)
