As before, this patch is cut against 3.3.4 and not 3.4.x.

Hi Mike, is this issue in 3.3/3.4/3.5? Then typically we'd need patch(es) that apply to each cleanly. Would you mind creating such a patch? (3.4/3.5 may only require a single patch, not sure).

Patches cut against current branch-3.3, branch-3.4, and trunk

Examining the code, I have no reason to believe the problem is fixed in 3.4 or trunk. I haven't tested there, however; we're seeing this in production with 3.3.

shrug I can't reproduce the patch apply failure, I just cut those patches from the heads of the three branches and I can apply them without a hunk failure.

Sorry for the trouble Mike. I believe the issue is that you are using git without the "--no-prefix" option. I typically do

git diff --no-prefix HEAD^..HEAD

from the same directly you're currently using (toplevel, ie the one containing "src", as in src/contrib/..."). Notice the original patch has a/src/con.. or b/src/con... which svn/patch don't like. Could you give that a try?

Thanks!

Cut a -p0 patch instead of a -p1 patch (patch is the same for all three branches).

Patch is applying cleanly now, however would you mind adding a test that verifies this case? That will ensure we don't regress in future versions. Thanks!

In writing the test, I discovered the real problem: zookeeper-c treats the session password as a \0-terminated string, but the java generates the session password as a 16-byte binary blob, where \0 is data. Some ideas for fixing that are 1) break the c api and add a passwd_len to the clientid_t or 2) change ZooKeeperServer.generatePasswd to not make \0. Which is better is up to you, I think.

Currently everything that uses the C api and does not pass in a session password will randomly break if they expect session passwords to work (since the password will be truncated to the null every time it crosses the C<=>Python interface). I would expect the perl api has the same problem. With this patch, the password will not be truncated (though the tradeoff is you must pass a 16-byte string from python).
