Hi Robert,

Yeah, this error message is not so great.
The relevant code is in sha1_file.c.
fd = create_tmpfile(tmpfile, sizeof(tmpfile), filename);
while (fd < 0 && errno == EMFILE && unuse_one_window(packed_git, -1))
fd = create_tmpfile(tmpfile, sizeof(tmpfile), filename);
if (fd < 0) {
if (errno == EACCES)
return error("insufficient permission for adding an object to repository database %s\n", get_object_directory());
else
return error("unable to create temporary sha1 filename %s: %s\n", tmpfile, strerror(errno));
}
create_tmpfile() creates a filename of the form
./objects/e6/tmp_obj_<random letters> and tries to open that file.
The random value is based on the current time and the process ID of
the current process. If the file exists, it tries again with another
collection of random letters, up to 16384 times.
In your case, all 16384 trials yielded the same result: file already
existed. As a workaround, I’d suggest
rm -f .git/objects/??/tmp_obj_*
but it might be nice to get a listing with "ls -lR .git/objects" first
for post-mortem analysis.
And presumably the directory filled with temporary files that could
not be renamed to a proper name for some reason. Probably a permissions
problem, as Chris suggested.

Subject: write_loose_object(): improve error message for some mkstemp failures
If the .git/objects/ab/ directory fills up with tmp_obj_ files, the
result is a cryptic error:
error: unable to create temporary sha1 filename ./objects/e6: File exists
Replace it with the slightly less cryptic
error: cannot write temporary file under ./objects/e6: all the good filenames are taken

Here is an answer from the last time it came up[1]:
See http://thread.gmane.org/gmane.comp.version-control.git/136500
Short answer: the usual method is to report bugs to the list,
preferably with a patch for t/ or even better, a fix.
