add59c4708 Merge branch 'mm/p4-unshelve-windows-fix'
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.

c3f2358de3 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.

0108f47eb3 git-p4: allow unshelving of branched files
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.

d15068a650 git-p4: respect excluded paths when detecting branches
Currently, excluded paths are only handled in the following cases:
 * no branch detection;
 * branch detection with using clientspec.

However, excluded paths are not respected in case of
branch detection without using clientspec.

Fix this by consulting the list of excluded paths
when splitting files across branches.

a2bee10ad9 git-p4: don't exclude other files with same prefix
Make sure not to exclude files unintentionally
if exclude paths are specified without a trailing /.
I.e., don't exclude "//depot/file_dont_exclude" if run with "-//depot/file".

Do this by ensuring that paths without a trailing "/" are only matched completely.

Also, abort path search on the first match as a micro-optimization.

Currently, `cloneExclude` array is being groomed (by removing trailing "...")

(since `extractFilesFromCommit()` is called on every imported changeset)

As a micro-optimization, do it once while parsing arguments.

f2768cb343 git-p4: match branches case insensitively if configured
git-p4 knows how to handle case insensitivity in file paths
if core.ignorecase is set.
However, when determining a branch for a file,
it still does a case-sensitive prefix match.
This may result in some file changes to be lost on import.

For example, given the following commits
 1. add //depot/main/file1
 2. add //depot/DirA/file2
 3. add //depot/dira/file3
 4. add //depot/DirA/file4
and "branchList = main:DirA" branch mapping,
commit 3 will be lost.

So, do branch search case insensitively if running with core.ignorecase set.
Teach splitFilesIntoBranches() to use the p4PathStartsWith() function
for path prefix matches instead of always case-sensitive match.

2dda741279 git-p4: detect/prevent infinite loop in gitCommitByP4Change()
Under certain circumstances, gitCommitByP4Change() can enter an infinite
loop resulting in `git p4 sync` hanging forever.

The problem is that
`git rev-list --bisect <latest> ^<earliest>` can return `<latest>`,
which would result in reinspecting <latest> and potentially an infinite loop.

This can happen when importing just a subset of P4 repository
and/or with explicit "--changesfile" option.

A real-life example:

89143ac28a git-p4: fully support unshelving changelists
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.

3deed5e078 git-p4: auto-size the block
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

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.

f55b87c1c7 git-p4: add options --commit and --disable-rebase
On a daily work with multiple local git branches, the usual way to
submit only a specified commit was to cherry-pick the commit on
master then run git-p4 submit.  It can be very annoying to switch
between local branches and master, only to submit one commit.  The
proposed new way is to select directly the commit you want to
submit.

Add option --commit to command 'git-p4 submit' in order to submit
only specified commit(s) in p4.

On a daily work developping software with big compilation time, one
may not want to rebase on his local git tree, in order to avoid long
recompilation.

Add option --disable-rebase to command 'git-p4 submit' in order to
disable rebase after submission.

123f631761 git-p4: add unshelve command
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"

The change adds a new Unshelve command class. This just runs the
existing P4Sync code tweaked to handle a shelved changelist.

8cf422dbf1 git-p4: update multiple shelved change lists
--update-shelve can now be specified multiple times on the
command-line, to update multiple shelved changelists in a single
submit.

This then means that a git patch series can be mirrored to a
sequence of shelved changelists, and (relatively easily) kept in
sync as changes are made in git.

Note that Perforce does not really support overlapping shelved
changelists where one change touches the files modified by
another. Trying to do this will result in merge conflicts.

7560f547e6 treewide: correct several "up-to-date" to "up to date"
Follow the Oxford style, which says to use "up-to-date" before the noun,
but "up to date" after it. Don't change plumbing (specifically
send-pack.c, but transport.c (git push) also has the same string).

This was produced by grepping for "up-to-date" and "up to date". It
turned out we only had to edit in one direction, removing the hyphens.

Fix a typo in Documentation/git-diff-index.txt while we're there.

b596b3b920 git-p4: parse marshal output "p4 -G" in p4 changes
The option -G of p4 (python marshal output) gives more context about the
data being output. That's useful when using the command "change -o" as
we can distinguish between warning/error line and real change description.

This fixes the case where a p4 trigger for  "p4 change" is set and the command git-p4 submit is run.

eff451101d git-p4: don't use name-rev to get current branch
git-p4 was using "git name-rev" to find out the current branch.

That is not safe, since if multiple branches or tags point at
the same revision, the result obtained might not be what is
expected.

Instead use "git symbolic-ref".

78871bf46f git-p4: add read_pipe_text() internal function
The existing read_pipe() function returns an empty string on
error, but also returns an empty string if the command returns
an empty string.

This leads to ugly constructions trying to detect error cases.

Add read_pipe_text() which just returns None on error.

a8b05162e8 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.

c3c2b05776 git-p4: fix git-p4.mapUser on Windows
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
Git author name and email address", 2016-03-01)

This issue should be caught by the test introduced in 10d08a1, however
would require running on Windows to reproduce.

Using splitlines solves this issue, by splitting config on all
typical delimiters ('\n', '\r\n' etc.)

bc233524c9 git-p4: do not pass '-r 0' to p4 commands
git-p4 crashes when used with a very old p4 client version
that does not support the '-r <number>' option in its commands.

Allow making git-p4 work with old p4 clients by setting git-p4.retries to 0.

Alternatively git-p4.retries could be made opt-in.
But since only very old, barely maintained p4 versions don't support
the '-r' option, the setting-retries-to-0 workaround would do.

The "-r retries" option is present in Perforce 2012.2 Command Reference,
but absent from Perforce 2012.1 Command Reference.
