On the previous commit we changed text and subject from unicode
to str. After a better solution from @cassiobotaro, we're using
unicode again, selecting the encoding as the one passed via encoding
parameter.
On PR #964 @matclab forced the encoding of both subject and
text variables to unicode.
After merging it, matclab realized that when we send Unicode
text to the method it raises an exception and asked if he should
change the commit. Unfortunately this thing was kept untouched.
This problem exists because we previously encode the unicode variables
to utf-8 (for instance here https://github.com/web2py/web2py/blob/master/gluon/tools.py#L478-L481) and then force again to unicode. This piece of code shows what happens:
```
>>> a = u'áéí'
>>> a
u'\xe1\xe9\xed'
>>> b = a.encode('utf-8')
>>> b
'\xc3\xa1\xc3\xa9\xc3\xad'
>>> unicode(a)
u'\xe1\xe9\xed'
>>> unicode(b)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)
```
If we force to str, just like @matclab suggested, we solve this issue.
This is a refactor of everything web2py uses with redis.
Specifically:
- a refactored redis_cache.py that fixes#958, allowing a "fail
gracefully" behaviour in case redis is not available
- a refactored redis_session.py that blocks less with with_lock=True
(although still not optimal)
- a new (and NEEDED) redis_utils.py that serves as the base for
everything else, allowing an RConn object that you can freely use as a
redis.StrictRedis connection, and that you can override in case you're
using a different library (or that web2py will use in case redis-py
won't be the de-facto standard around)
- a newly - and much anticipated - redis_scheduler.py. It's a slip-in
replacement for the standard scheduler that uses redis for workers
coordination. Feel free to dig in the code and improve it.
For redis_cache and redis_session changes are BREAKING. It means that
users will need to change the import locations and tune a bit the code.
Now every module depends on an gluon.contrib.redis_utils.RConn object
(or similar) that in turns is very similar to a redis.StrictRedis one.
The redis instance is EXTERNAL to the modules themselves (no more "host,
port, db, password" parameters in RedisCache or RedisSession)
See the relevant docstrings for usage examples
now elements with data-w2p_disable are not disabled.
in addition, for non-ajax forms, disabled submit buttons are reenabled
after 5 seconds
plus reindented, refactored AND jslinted
- if hmac.compare_digest is there, we should use it instead of our own
fallback.
- jwt handler has been updated to use utils.compare (reported in
#web2py-users)
- includes the same mods as https://github.com/web2py/web2py/pull/1146
