2015-08-28git-p4: honor core.ignorecase when using P4 client specsLars Schneider
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".

2015-06-10git-p4: fixing --changes-block-size handlingLuke Diamand
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. Signed-off-by: Luke Diamand <luke@diamand.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2015-04-23git-p4: improve client path detection when branches are usedVitor Antunes
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 "/...".

The diff information render the spec file unusable as is by p4, do not include it when run with --prepare-p4-only so that the given file can be directly passed to p4. 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 quick review of the patch before submitting it. And does not cause problems with p4 as we remove it programmatically.

2014-01-22git p4 test: do not pollute /tmpPete Wyckoff
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.

2014-01-22git p4: work around p4 bug that causes empty symlinksPete Wyckoff
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.

2013-03-11git p4: avoid expanding client paths in chdirMiklós Fazekas
The generic chdir() helper sets the PWD environment variable, as that is what is used by p4 to know its current working directory. Normally the shell would do this, but in git-p4, we must do it by hand. However, when the path contains a symbolic link, os.getcwd() will return the physical location. If the p4 client specification includes symlinks, setting PWD to the physical location causes p4 to think it is not inside the client workspace. It complains, e.g. Path /vol/bar/projects/foo/... is not under client root /p/foo One workaround is to use AltRoots in the p4 client specification, but it is cleaner to handle it directly in git-p4. Other uses of chdir still require setting PWD to an absolute path so p4 features like P4CONFIG work. See bf1d68f (git-p4: use absolute directory for PWD env var, 2011-12-09).

2013-01-27git p4: scrub crlf for utf16 files on windowsPete Wyckoff
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.

2013-01-27git p4: remove unreachable windows \r\n conversion codePete Wyckoff
Replacing \r\n with \n on windows was added in c1f9197 (Replace \r\n with \n when importing from p4 on Windows, 2007-05-24), to work around an oddity with "p4 print" on windows. Text files are printed with "\r\r\n" endings, regardless of whether they were created on unix or windows, and regardless of the client LineEnd setting. As of d2c6dd3 (use p4CmdList() to get file contents in Python dicts. This is more robust., 2007-05-23), git-p4 uses "p4 -G print", which generates files in a raw format. As the native line ending format if p4 is \n, there will be no \r\n in the raw text. Actually, it is possible to generate a text file so that the p4 representation includes embedded \r\n, even though this is not normal on either windows or unix. In that case the code would have mistakenly stripped them out, but now they will be left intact.
