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.

git p4: scrub crlf for utf16 files on windows
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.

# Retrieve changes a block at a time, to prevent running
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.

git p4: gracefully fail if some commits could not be applied
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.

git p4: gracefully fail if some commits could not be applied
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.

git p4: gracefully fail if some commits could not be applied
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.

git p4: work around p4 bug that causes empty symlinks
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.

# But ascii text saved as -t utf16 is completely mangled.
# Invoke print -o to get the real contents.
git p4: scrub crlf for utf16 files on windows
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.
