c# - Autofac how to update registration? -


from autofac documentation:

autofac overrides component registrations default. means application can register of default components, read associated configuration file override have been customized deployment environment.

how can override registration, firstly make assebly scan,

builder    .registerassemblytypes(assembly)                  .propertiesautowired(propertywiringoptions.allowcirculardependencies)    .asimplementedinterfaces()    .asself()    .instanceperrequest();

then try update registration without scope tag

builder     .registertype<notperrequesttype>()     .asimplementedinterfaces();

but there still 2 registrations , still getting no matching tag error wher resolve notperrequesttype.

you can't change registration post-facto. you'd need exclude stuff don't want registered during assembly scanning using linq.

builder.registerassemblytypes(assembly)        .where(t => t != typeof(notperrequesttype))        ...

then you'll have 1 registration - 1 manually register later.

this is, unfortunately, "two-edged sword" of trying automatically just register everything , realizing have exceptions. need use blanket assembly scanning great care.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
