Perforce repositories can contain large (binary) files. Migrating these

Perforce keeps the encoding of a path as given by the originating OS.
Git expects paths encoded as UTF-8. Add a config to tell git-p4 what

With --detect-labels enabled, git-p4 will try to create tags
using git fast-import by writing a "tag" clause to the

If the commit that the tag references has not yet actually
been processed by fast-import, then the tag can't be created
and git-p4 fails to import the P4 label.

Perforce depot may record paths in mixed cases, e.g. "p4 files" may
show that there are these two paths:
//depot/Path/to/file1
//depot/pATH/to/file2
and with "p4" or "p4v", these end up in the same directory, e.g.
//depot/Path/to/file1
//depot/Path/to/file2
which is the desired outcome on case insensitive systems.
If git-p4 is used with client spec "//depot/Path/...", however, then
all files not matching the case in the client spec are ignored (in
the example above "//depot/pATH/to/file2").
Fix this by using the path case that appears first in lexicographical
order when core.ignorecase is set to true. This behavior is consistent
with "p4" and "p4v".

More Perforce row number limit workaround for "git p4".
* ld/p4-changes-block-size:
git-p4: fixing --changes-block-size handling
git-p4: add tests for non-numeric revision range
git-p4: test with limited p4 server results
git-p4: additional testing of --changes-block-size
The --changes-block-size handling was intended to help when
a user has a limited "maxscanrows" (see "p4 group"). It used
"p4 changes -m $maxchanges" to limit the number of results.
Unfortunately, it turns out that the "maxscanrows" and "maxresults"
limits are actually applied *before* the "-m maxchanges" parameter
is considered (experimentally).
Fix the block-size handling so that it gets blocks of changes
limited by revision number ($Start..$Start+$N, etc). This limits
the number of results early enough that both sets of tests pass.
Note that many other Perforce operations can fail for the same
reason (p4 print, p4 files, etc) and it's probably not possible
to workaround this. In the real world, this is probably not
usually a problem.

git p4 attempts to better handle branches in Perforce.
* va/p4-client-path:
git-p4: improve client path detection when branches are used
t9801: check git-p4's branch detection with client spec enabled

git-p4: use -m when running p4 changes
Perforce allows client side file/directory remapping through
the use of the client view definition that is part of the
user's client spec.
To support this functionality while branch detection is
enabled it is important to determine the branch location in
the workspace such that the correct files are patched before
Perforce submission. Perforce provides a command that
facilitates this process: p4 where.
This patch does two things to fix improve file location
detection when git-p4 has branch detection and use of client
spec enabled:
1. Enable usage of "p4 where" when Perforce branches exist
in the git repository, even when client specification is
used. This makes use of the already existing function
p4Where.
2. Allow identifying partial matches of the branch's depot
path while processing the output of "p4 where". For
robustness, paths will only match if ending in "/...".

With --prepare-p4-only, git-p4 already tells the user it can use
p4 submit with the generated spec file. This fails because of the
diff being present in the file. Not including the diff fixes that.
Without --prepare-p4-only, keeping the diff makes sense for a

Generating the submit template for p4 uses tempfile.mkstemp(),
which by default puts files in /tmp. For a test that fails,
possibly on purpose, this is not cleaned up. Run with TMPDIR
pointing into the trash directory so the temp files go away
with the test results.
To do this required some other minor changes. First, the editor
is launched using system(editor + " " + template_file), using
shell expansion to build the command string. This doesn't work
if editor has a space in it. And is generally unwise as it's
easy to fool the shell into doing extra work. Exec the args
directly, without shell expansion.
Second, without shell expansion, the trick of "P4EDITOR=:" used
in the tests doesn't work. Use a real command, true, as the
non-interactive editor for testing.

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.

"git p4" does not support many of the view wildcards, such as * and
%%n. It only knows the common ... mapping, and exclusions.
Redo the entire wildcard code around the idea of directly querying
the p4 server for the mapping. For each commit, invoke "p4 where"
with committed file paths as args and use the client mapping to
decide where the file goes in git.
This simplifies a lot of code, and adds support for all wildcards
supported by p4. Downside is that there is probably a 20%-ish
slowdown with this approach.
