Previously, the script would invoke subprocess functions setting the
shell argument True if the command argument was a string, setting it
False otherwise.
This patch replaces this implicit type-driven behaviour with explicit
shell arguments specified by the caller.
The apparent motive for the implict behaviour is that the subprocess
functions do not divide command strings into args. Invoking
subprocess.call("echo hello") will attempt to execute a program by the
name "echo hello". With subprocess.call("echo hello", shell=True), sh
-c "echo hello" will be executed instead, which will cause the command
and args to be divided by spaces.
Eventually, all usage of shell=True, that is not necessary for some
purpose beyond parsing command strings, should be removed. For now,
this patch makes the usage of shells explicit.

The "rollback" verb implements a simple algorithm which takes the set of
remote perforce tracker branches, or optionally, the complete collection
of local branches in a git repository, and deletes commits from these
branches until there are no commits left with a perforce change number
greater than than a user-specified change number. If the base of a git
branch has a newer change number than the user-specified maximum, then
the branch is deleted.
In future, there might be an argument for the addition of some kind of
"reset this branch back to a given perforce change number" verb for
git-p4. However, in its current form it is unlikely to be useful to
users for the following reasons:
* The verb is completely undocumented. The only description provided
contains the following text: "A tool to debug the multi-branch
import. Don't use :)".
* The verb has a very narrow purpose in that it applies the rollback
operation to fixed sets of branches - either all remote p4 branches,
or all local branches. There is no way for users to specify branches
with more granularity, for example, allowing users to specify a
single branch or a set of branches. The utility of the current
implementation is therefore a niche within a niche.
Given these shortcomings, this patch removes the verb from git-p4.

The git-p4 "debug" verb is described as "A tool to debug the output of
p4 -G".
The verb is not documented in any detail, but implements a function
which executes an arbitrary p4 command with the -G flag, which causes
perforce to format all output as marshalled Python dictionary objects.
The verb was implemented early in the history of git-p4, and may once
have served a useful purpose to the authors in the early stages of
development. However, the "debug" verb is no longer being used by the
current developers (and users) of git-p4, and whatever purpose the verb
previously offered is easily replaced by invoking p4 directly.
This patch therefore removes the verb from git-p4.

The git-p4 script reports file sizes in various log messages.
Previously, in each case the script would print them as the number of
bytes divided by 1048576 i.e. the size in mebibytes, rounded down to an
integer. This resulted in small files being described as having a size
of "0 MB".
This patch replaces the existing behaviour with a new helper function:
format_size_human_readable, which takes a number of bytes (or any other
quantity), and computes the appropriate prefix to use: none, Ki, Mi, Gi,
Ti, Pi, Ei, Zi, Yi.
For example, a size of 123456 will now be printed as "120.6 KiB" greatly
improving the readability of the log output.
Large valued prefixes such as pebi, exbi, zebi and yobi are included for
completeness, though they not expected to appear in any real-world

RCS keywords are strings that are replaced with information from
Perforce. Examples include $Date$, $Author$, $File$, $Change$ etc.
Perforce resolves these by expanding them with their expanded values
when files are synced, but Git's data model requires these expanded
values to be converted back into their unexpanded form.
Previously, git-p4.py would implement this behaviour through the use of
regular expressions. However, the regular expression substitution was
applied using decoded strings i.e. the content of incoming commit diffs
was first decoded from bytes into UTF-8, processed with regular
expressions, then converted back to bytes.
Not only is this behaviour inefficient, but it is also a cause of a
common issue caused by text files containing invalid UTF-8 data. For
files created in Windows, CP1252 Smart Quote Characters (0x93 and 0x94)
are seen fairly frequently. These codes are invalid in UTF-8, so if the
script encountered any file containing them, on Python 2 the symbols
will be corrupted, and on Python 3 the script will fail with an
exception.
This patch replaces this decoding/encoding with bytes object regular
expressions, so that the substitution is performed directly upon the
source data with no conversions.
A test for smart quote handling has been added to the
t9810-git-p4-rcs.sh test suite.

For every new branch that git-p4 imports, it needs to find the commit
where it branched off its parent branch. While p4 doesn't record this
information explicitly, the first changelist on a branch is usually an
identical copy of the parent branch.
The method searchParent() tries to find a commit in the history of the
given "parent" branch whose tree exactly matches the initial changelist
of the new branch, "target". The code iterates through the parent
commits and compares each of them to this initial changelist using
diff-tree.
Since we already know the tree object name we are looking for, spawning
diff-tree for each commit is wasteful.
Use the "--format" option of "rev-list" to find out the tree object name
of each commit in the history, and find the tree whose name is exactly
the same as the tree of the target commit to optimize this.
This results in a considerable speed-up, at least on Windows. On one
Windows machine with a fairly large repository of about 16000 commits in
the parent branch, the current code takes over 7 minutes, while the new
code only takes just over 10 seconds for the same changelist:

git-p4.py: fix --prepare-p4-only error with multiple commits
When using git p4 submit with the --prepare-p4-only option, the program
should prepare a single p4 changelist and notify the user that more
commits are pending and then stop processing.
A bug has been introduced by the p4-changelist hook feature that
causes the program to continue to try and process all pending
changelists at the same time.
The function applyCommit returns True when applying the commit
was successful and the program should continue. However, when the
optional flag --prepare-p4-only is set, the program should stop
after the first application.
Change the logic in the run method for P4Submit to check for the
flag --prepare-p4-only after successfully completing the applyCommit
method.
Be aware - this change will fix the existing test error in t9807.23
for --prepare-p4-only. However there is insufficent coverage for
this flag. If more than 1 commit is pending submission to P4, the
method will properly prepare the P4 changelist, however it will
still exit the application with an exitcode of 1.
The current documentation does not define what the exit code should be
in this condition.

Perforce allows you commit files and directories with the same name,

the files recovers the repository.
When this happens we want git-p4 to recover in the same way as
perforce.
Note that Perforce has this change in their 2017.1 version:
Bugs fixed in 2017.1

will attempt to clear the expanded text from the files and re-apply
the patch. The current version of git-p4 does not tell the user the

The git command "commit" supports a number of hooks that support
changing the behavior of the commit command. The git-p4.py program only
has one existing hook, "p4-pre-submit". This command occurs early in
the process. There are no hooks in the process flow for modifying
the P4 changelist text programmatically.
Adds 3 new hooks to git-p4.py to the submit option.
The new hooks are:
* p4-prepare-changelist - Execute this hook after the changelist file
has been created. The hook will be executed even if the
--prepare-p4-only option is set. This hook ignores the --no-verify
option in keeping with the existing behavior of git commit.
* p4-changelist - Execute this hook after the user has edited the
changelist. Do not execute this hook if the user has selected the
--prepare-p4-only option. This hook will honor the --no-verify,
following the conventions of git commit.
* p4-post-changelist - Execute this hook after the P4 submission process
has completed successfully. This hook takes no parameters and is
executed regardless of the --no-verify option. It's return value will
not be checked.
The calls to the new hooks: p4-prepare-changelist, p4-changelist,
and p4-post-changelist should all be called inside the try-finally
block.

In preparation for adding new hooks to the submit method of git-p4,
restructure the applyCommit function in the P4Submit class. Make the
following changes:
* Move all the code after the definition of submitted = False into the
Try-Finally block. This ensures that any error that occurs will
properly recover. This is not necessary with the current code because
none of it should throw an exception, however the next set of changes
will introduce exceptional code.
Existing flow control can remain as defined - the if-block for
prepare-p4-only sets the local variable "submitted" to True and exits
the function. New early exits, leave submitted set to False so the
Finally block will undo changes to the P4 workspace.
* Make the small usability change of adding an empty string to the
print statements displayed to the user when the prepare-p4-only option
is selected. On Windows, the command print() may display a set of
parentheses "()" to the user when the print() function is called with
no parameters. By supplying an empty string, the intended blank line
will print as expected.
* Fix a small bug when the submittedTemplate is edited by the user
and all content in the file is removed. The existing code will throw
an exception if the separateLine is not found in the file. Change this
code to test for the separator line using a find() test first and only
split on the separator if it is found.
* Additionally, add the new behavior that if the changelist file has
been completely emptied that the Submit action for this changelist
will be aborted.

This commit is in preparation of introducing new p4 submit hooks.
The current code in the python script git-p4.py makes the assumption
that the git hooks can be executed by subprocess.call() function.
However, when git is run on Windows, this may not work as expected.
The subprocess.call() does not cover all the use cases for properly
executing the various types of executable files on Windows.
Prepare for remediation by adding a new function, run_git_hook, that
takes 2 parameters:
* the short filename of an optionally registered git hook
* an optional list of parameters
The run_git_hook function will honor the existing behavior seen in the
current code for executing the p4-pre-submit hook:
* Hooks are looked for in core.hooksPath directory.
* If core.hooksPath is not set, then the current .git/hooks directory
is checked.
* If the hook does not exist, the function returns True.
* If the hook file is not accessible, the function returns True.
* If the hook returns a zero exit code when executed, the function
return True.
* If the hook returns a non-zero exit code, the function returns False.
Add the following additional functionality if git-p4.py is run on
Windows.
* If hook file is not located without an extension, search for
any file in the associated hook directory (from the list above) that
has the same name but with an extension.
* If the file is still not found, return True (the hook is missing)
Add a new function run_hook_command() that wraps the OS dependent
functionality for actually running the subprocess.call() with OS
dependent behavior:
If a hook file exists on Windows:
* If there is no extension, set the launch executable to be SH.EXE
- Look for SH.EXE under the environmental variable EXEPATH in the
bin/ directory.
- If %EXEPATH%/bin/sh.exe exists, use this as the actual executable.
- If %EXEPATH%/bin/sh.exe does not exist, use sh.exe
- Execute subprocess.call() without the shell (shell=False)
* If there is an extension, execute subprocess.call() with teh shell
(shell=True) and consider the file to be the executable.
The return value from run_hook_command() is the subprocess.call()
return value.
These functions are added in this commit, but are only staged and not
