iphone - NSXMLParser Memory Leak from Second Parse Call -

-

update: while leaks instrument points first call [parser parse];, have identified leak occurs when make call second time. don't see in nsxmlparser class reference or documentation indicates 1 can't re-parse. missing something? should create new nsxmlparser each time wish parse document?

i trying track down leak in xml parsing code iphone app. i've searched through other posts on leaks nsxmlparser, haven't found answers use, appreciate help.

the instruments leaks tool detecting leak in following code:

nsdata* data = [nsdata datawithcontentsoffile: [[nsbundle mainbundle] pathforresource: @"collisiongraph" oftype: @"graphml"]]; nsxmlparser* parser = [[[nsxmlparser alloc] initwithdata: data] autorelease]; [parser setdelegate:self]; [parser parse];    <<<<< leak here according leaks self.currentpass++;  ...  [parser parse]; self.currentpass++;

i removed of code delegate callback methods, didn't stop leak.

-(void)parser:(nsxmlparser *)parser didstartelement:(nsstring *)elementname   namespaceuri:(nsstring *)namespaceuri  qualifiedname:(nsstring *)qualifiedname     attributes:(nsdictionary *)attributedict { }  -(void)parser:(nsxmlparser *)parser foundcharacters:(nsstring *)string { }    -(void)parser:(nsxmlparser *)parser didendelement:(nsstring *)elementname  namespaceuri:(nsstring *)namespaceuri  qualifiedname:(nsstring *)qname { }

here view in instruments http://i22.photobucket.com/albums/b311/erithil/parserleak.png (linked because don't have rep post images).

i'm stumped this, suggestions appreciated. in advance.

it leak within nsxmlparser (if e.g. xmlcleanupparser() not called on underlying libxml) or reusable memory mistakenly flagged leak. think it's typically happens parsers due them reusing (and not releasing?) allocated memory.

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.
