java - How to override some classes in a jar in WEB-INF/lib with another jar in JBoss EAP? -


if class override called com.example.fooservlet , class inside jar web-inf/lib/foo.jar, how override class called com.example.fooservlet in jar, bar.jar?

or there way make sure 1 in bar.jar loaded first?

making bar.jar module no-go because fooservlet imports tons of classes many jars in web-inf/lib.

as stated above, tried contain bar.jar in module, got class not found or no class def error (can't remember clearly) fooservlet extends/implements classes/interfaces in 3rd party jars in web-inf/lib.

i'm not allowed touch foo.jar or of jars existing in web-inf/lib.

you said cannot touch existing jars, , seem imply can add jar of yours web-inf/lib.

according this:

  • there no specified order of precedence jars under web-inf/lib/*.jar.
    if add bar.jar in there, don't know if loaded before or after foo.jar.
  • the servlet spec says classes under web-inf/classes must loaded before under web-inf/lib/*.jar

assuming can add jar under web-inf/lib, should able add class (or several) under web-inf/classes, without touching ones in place.
so, if want classes bar.jar loaded first, can unzip contents of jar under web-inf/classes instead (or class want loaded in priority -- example web-inf/classes/com/example/fooservlet.class).

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 ...
