python - Jython and the xml.sax parser - strange error -

-

i getting started python/jython , sax parser (xml.sax). wrote simple content handler test.

from __future__ import with_statement   xml.sax import make_parser, handler xml.sax.handler import contenthandler  class countinghandler(contenthandler):      def __init__(self):         self.counter = 0      def startelement(self, name, attrs):         self.counter += 1  def main(argv=sys.argv):     parser = make_parser()     h = countinghandler()     parser.setcontenthandler(h)     open(argv[1], "r") input:         parser.parse(input)

when run on documents (not all), error:

traceback (most recent call last):   file "src/sciencenetworks/xmltools.py", line 93, in <module>     sys.exit(main())   file "src/sciencenetworks/xmltools.py", line 88, in main     parser.parse(input)   file "/amd.home/home/staudt/workspace/jython/lib/xml/sax/drivers2/drv_javasax.py", line 141, in parse     self._parser.parse(jyinputsourcewrapper(source))   file "/amd.home/home/staudt/workspace/jython/lib/xml/sax/drivers2/drv_javasax.py", line 90, in resolveentity     return jyinputsourcewrapper(self._resolver.resolveentity(pubid, sysid))   file "/amd.home/home/staudt/workspace/jython/lib/xml/sax/drivers2/drv_javasax.py", line 75, in __init__     if source.getbytestream(): attributeerror: 'unicode' object has no attribute 'getbytestream'

when source code of drv_javasax.py, seems input not recognized file object, is.
ideas on how fix this?

i think it's bug: http://bugs.jython.com/issue1488. fixed in jython 2.5.2-b1: http://www.jython.org/latest.html

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
