wcfs: _mntpt_4zurl: Fix it to accept strings.
Strings cannot be directly hashed without encoding them first, or an error will be raised: ```python ______________________________ test_zsync_resync _______________________________ @func def test_zsync_resync(): zstor = testdb.getZODBStorage() defer(zstor.close) > db, zconn, wconn = _zsync_setup(zstor) wcfs/client/_wczsync_test.py:112: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ../../venvs/wendelin.core/lib/python3.9/site-packages/decorator.py:232: in fun return caller(func, *(extras + args), **kw) ../pygolang/golang/__init__.py:125: in _ return f(*argv, **kw) wcfs/client/_wczsync_test.py:53: in _zsync_setup wc = wcfs.join(zurl) wcfs/__init__.py:201: in join mntpt = _mntpt_4zurl(zurl) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ zurl = 'file:///srv/slapgrid/slappart66/tmp/testdb_fs.xstpbg49/1.fs' def _mntpt_4zurl(zurl): # normalize zurl so that even if we have e.g. two neos:// urls coming # with different paths to ssl keys, or with different order in the list of # masters, we still have them associated with the same wcfs mountpoint. zurl = zurl_normalize_main(zurl) m = hashlib.sha1() > m.update(zurl) E TypeError: Strings must be encoded before hashing ``` We fix this error by encoding the string as UTF8 before hashing it. -------- kirr: Use b instead of doing if isinstance(zurl, six.text_type): zurl = zurl.encode("utf-8") wcfs already takes this approach of using b in other places - for example in tDB.change: # change schedules zf to be changed according to changeDelta at commit. # # changeDelta: {} blk -> data. # data can be both bytes and unicode. <-- NOTE def change(t, zf, changeDelta): assert isinstance(zf, ZBigFile) zfDelta = t._changed.setdefault(zf, {}) for blk, data in six.iteritems(changeDelta): data = b(data) <-- NOTE ... /reviewed-by @kirr /reviewed-on nexedi/wendelin.core!27
