python - Jython and the SAX Parser: No more than 64000 entities allowed? -

-

i've done simple test of xml.sax parser in jython on large xml file (800 mb) , encountered following error:

traceback (most recent call last):   file "src/project/xmltools.py", line 92, in <module>     sys.exit(main())   file "src/project/xmltools.py", line 87, in main     parser.parse(open(argv[1], "r"))   file "/amd.home/home/user/workspace/jython-2.5.2/lib/xml/sax/drivers2/drv_javasax.py", line 146, in parse     self._parser.parse(jyinputsourcewrapper(source))   file "/amd.home/home/user/workspace/jython-2.5.2/lib/xml/sax/drivers2/drv_javasax.py", line 59, in fatalerror     self._err_handler.fatalerror(_wrap_sax_exception(exc))   file "/amd.home/home/user/workspace/jython-2.5.2/lib/xml/sax/handler.py", line 38, in fatalerror     raise exception xml.sax._exceptions.saxparseexception: <unknown>:1:1: parser has encountered more "64,000" entity expansions in document; limit imposed application.

what matter "limit imposed application" , how can override it?

i have tried use java xml library nu.xom , ran same error.

try setting entityexpansionlimit property higher value 64000. see http://download.oracle.com/javase/1.5.0/docs/guide/xml/jaxp/jaxp-compatibility_150.html#jaxp_security.

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.
