OS X and umlauts in file names

OS X and umlauts in file names

[Thomas Singer]

I'm on an English OS X 10.6.2 and I created a sample file with umlauts in
its name (Überlänge.txt). When I try to stage the file in the terminal, I
can't complete the file name by typing the Ü and hitting the tab key, but I
can complete it by typing an U and hitting the tab key. Unfortunately, after
executing

 git stage Überlänge.txt

I invoked

 git status

and it still shows the file as new file. Should I set some environment
variable to be able to work with files containing umlauts in the name?

Thanks in advance,
Tom

This is because of OS X's unicode normalisation.  Try any of the
many threads on the topic, e.g.,

  http://thread.gmane.org/gmane.comp.version-control.git/70688

The short version is that this Ü is in fact decomposed into an
U-umlaut duo.

Considering that this leads to endless fun[*] not just with git, and
that we German speakers have an easy way out (Ueberlaenge), I can only
suggest that you avoid umlauts wherever possible to preserve
the sanity of your users.

Übungen.  Took me a while to figure out what was going on.

Hi Thomas,

Thanks for the feed-back. I know the problem from SVN, too, but I had the
hope, that Git was smarter than SVN for this topic. IIRC, one could get SVN
working "somehow" with umlauts on OS X by setting some environment variable.
Unfortunately, I don't remember the details any more.

Basically, getting it "somehow" to work on OS X is just one minor step. IMHO
Git should standardize on file names in the repository and do the
platform-specific conversion independent of any locale setting, if needed.
Then and only then it would be possible to get the same characters out of
the repository, no matter whether the file was added or checked out on OS X,
Linux or Windows.

At the moment we've got a problem report regarding our SmartGit GUI client:
the user says, on command line it[1] works (German OS X) but not with
SmartGit, for me it doesn't even work on the command line (English OS X). As
you may know, Java uses characters for file names, the Java runtime
internally converts from the platform-specific byte-representation on disk
to characters. I can't simply tunnel the file name as byte array to the
invoked Git command - I simply don't know how to transform the characters of
the file name to a representation the Git command line client will
understand[2].

Tom

[1] e.g. to stage or commit files with umlauts in the file name
[2] executing an external command in Java also "only" works with strings
(aka characters), not with byte sequences

That is contrary to the design of Git which honors content (byte-wise!) as 
much as possible, and treats file names very much as content.

There were beginnings of supporting OSX' brain-damaged filename mangling, 
but an obnoxious OSX fan worked very hard on trying to defend the OSX 
design and to decry Git's respect for the raw bytes on this list, so hard 
that even the nicest developers had no fun working on this issue anymore.

This little background may help you understand why there is no solution 
implemented in Git yet.  And maybe quite a few developers are reluctant to 
discuss the issue and possible solutions due to said sad story, too.

Ouch - so git is respecting whatever name the user and/or OS have
picked, but Java wants to canonicalize it,  and whatever scheme it
uses does not match OSX? That must hurt Java usage on OSX a lot. Sure
they have a workaround...?

Suggestions:

1 - Configure Java to canonicalize in the same style as OSX. Actually,
OSX's canonicalization is somewhat arbitrary so I think it exposes a
call to canonicalize a string "the right way".

2 - Many git calls accept filenames via STDIN - Java will surely write
binary there...

3 - xargs with its -z parameter can complement #2

You've already got a bug before involving git at all. You create a 
file "Überlänge.txt", but OS X writes "U:berla:nge.txt" (typing the 
combining character umlaut as : so that you can see the difference), and 
the directory listing doesn't contain any files that start with Ü, so the 
terminal already can't find the file you created. Obviously, git is going 
to have all the problems that the OS-provided readline library has, and 
you're not going to be able to get predictable results in any case where 
user-supplied filenames are compared with directory listings.

Part of the problem is that OS X does a canonicalization that is not what 
anybody else does, so you hit the problem every single time, but the 
fundamental issue is that there isn't any way to tell, when you create a 
file, what name that file will be listed under.

Note that this isn't a matter of characters to byte sequences. OS X 
actually uses different characters for the filename in its listings than 
you've used.

If there's a difference between German and English versions, I suspect 
that it's actually that you're not using a German keyboard with a key 
that, under OS X, produces the two-character sequence U:, but using some 
method that produces the single character Ü. I'd guess that your SmartGit 
problem is that Java is converting the U: that the user typed into Ü, and 
passing it to the OS, which turns it back into U: and then doesn't list 
the file that Java thinks the user asked for.

Re: OS X and umlauts in file names

[Thomas Singer]

I agree, that getting it done correctly could be a long and hard (maybe
incompatible) way. Neglecting the problem or blaming platform specific
"anomalies" does not help to solve that serious real-world problem for the
end-user. IMHO, telling a user to not use non-US-ASCII characters in file
names to stay platform-independent seems not to be state-of-the-art and
would exclude a lot of users world-wide. Finally, everyone would expect Git
to be better than CVS, also at this point.

But what about getting it working "somehow" on OS X in a few minutes? What
should I do to be able to stage/commit/work with files containing umlauts in
their name on my English OS X (by specifying the file names) as it seems to
work magically on a German OS X? Is this topic already /documented/
somewhere (I couldn't find something)?

Thanks in advance,
Tom

To be more exact the problem is not that MacOS X uses denormalized
form (does file mangling).  This would be the problem only in
cross-platform development (where some developers would work from
different operating system).

The problem is that the name under which Git creates file is different
from the name MacOS X lists file (in readdir etc.).

Re: OS X and umlauts in file names

[Thomas Singer]

I've did following:

 toms-mac-mini:git-umlauts tom$ ls
 Überlänge.txt
 toms-mac-mini:git-umlauts tom$ git status
 # On branch master
 #
 # Initial commit
 #
 # Changes to be committed:
 #   (use "git rm --cached <file>..." to unstage)
 #
  #	new file:   "U\314\210berla\314\210nge.txt"
 #
 toms-mac-mini:git-umlauts tom$ git stage "U\314\210berla\314\210nge.txt"
 fatal: pathspec 'U\314\210berla\314\210nge.txt' did not match any files

Note, that I copy-pasted the file name which 'git status' showed to the
stage command. IMHO, this should work, especially, because different people
said Git would treat the file name as byte-array without interpreting it in
some kind.

From the user with the German OS X (for which the staging is said to work),
I've got the output of 'env' and hence also tried

 export LANG=de_DE.UTF-8

before doing the above steps, but with the same results. :(

The problem you are having is not because of the *encoding*, it's the
Normalization form that's messing things up. The fact is that in
Unicode there are two ways to represent many -- but not all --
accented characters.

- "composed": one code point for the accented character)
- "decomposed": two code points: one for the base letter, one or more
combining characters for the accents.

The composed code points are really just backward compatibility to
legacy encodings (like LATIN-1). If you want to actually support
(rather than just tolerate) unicode you have to know how to deal with
the decomposed form, and once you can do that there's little point
beyond backward compatibility in continuing to use composed form
internally.

The Subversion people have run into this same problem because they
made the same error of assuming that any given sequence of glyphs has
only one possible representation as unicode code points and thus only
one representation as UTF-8 bytes. Dionisos has done written up the
issues involved here:

Also, you can try with `find * -print0 | git-update-index --add
--stdin -z `. Find should report the exact filename that the OS has,
and git should add it as it is.

Background: git-add used to be a trivial shell script wrapping around
git-update-index. If you have a git checkout, try:

 git show f25933987f29070e9cd79dfddf03018010e82e80:git-add.sh

If git cannot track this file in a pure OSX world, there is a good
chance it's a bug in git.

In in this narrow test case (single machine, running OSX) git *must*
be able to do the right thing. If you work on multi-platform projects
however, there is a good chance a Windows or Linux user will commit a
file with a name that _when you checkout on OSX_, OSX will save with a
different (but "equivalent") name due to its funny decomposition
rules. And all sorts of "fun" will ensue.

cheers,

Try $'U\314\210berla\314\210nge.txt' instead.
"U\314\210berla\314\210nge.txt" is the same as
"U\\314\\210berla\\314\\210nge.txt" to the shell.

Hi Andreas,

Thank you for this hint. When trying

 toms-mac-mini:git-umlauts tom$ git stage $'U\314\210berla\314\210nge.txt'

git shows me no error or other output, but invoking 'git status' again shows
no difference, the file is still showing up as new file.

I've also tried to use double backslashes, but I could not enter a backslash
in the OS X Terminal (works fine in other applications). :(

Works for me on 10.6.2:

kore:~/foo (master)$ git stage Überlänge.txt
kore:~/foo (master)$ git st
# On branch master

 create mode 100644 "U\314\210berla\314\210nge.txt"
kore:~/foo (master)$ git st

nothing to commit (working directory clean)

Doesn't matter whether LANG and/or LC_* are set or not for me.

Wait, what's the problem here? It's staged according to the above,

OK, I've found it. This works (I have to complete the file name after having
typed an U):

toms-mac-mini:git-umlauts tom$ git rm --cached Überlänge.txt

Tom,

have you tried calling git-update-index --add
--stdin -z? Your original email stated

> we've got a problem report regarding our SmartGit GUI client

so it sounds like you are building a porcelain. In that case, the
sanest approach is to invoke git-update-index and write to its stdin.

cheers,

No, we don't do such a massive change immediately before a release.

We will try this out after release.

For those who are interested: I've got it working on OS X and Git was not
the problem, but Java. A longer time ago directory.list() or
directory.listFiles() returned the file names with decomposed characters (as
they are stored on OS X hard disk). Now (don't know which Java update
introduced this change) these methods return file names with composed
characters, so I had to decompose them before handing them to the git
executable call.

Nevertheless, the cross-platform-problem remains: if you add files with
umlauts in their names on non-OS X, you will not be able to use them on OS X.
