How to add response headers to data-urls by Chrome.webRequest -


i according chrome.webrequest want change data-urls responseheaders.but can't capture data request in chrome.webrequest.onheadersreceived.

am wrong ?

chrome.webrequest.onbeforerequest.addlistener(   function (details) {     const url = details.url      if(url == 'http://www.example.com/api/getusers') {       return {         redirecturl: 'data:application/json; charset=utf-8,' +  json.stringify({"a":1, "b": 2})       }     }      return {cancel: false}    },   {urls: ["<all_urls>"]},   ["blocking"] )  chrome.webrequest.onheadersreceived.addlistener(   function (details) {     console.log(details)  // can't capture data-urls      return {responseheaders:details.responseheaders};   },   {urls: ["<all_urls>"]},   ["responseheaders","blocking"] )

you can't capture data: urls webrequest api, since data: not supported scheme host permissions.

as such, <all_urls> permission/filter won't events data:

documentation quote:

the webrequest api exposes requests extension has permission see, given host permissions. moreover, following schemes accessible: http://, https://, ftp://, file://, ws:// (since chrome 58), wss:// (since chrome 58), or chrome-extension://.

i'm pretty sure there's feature request this, can't find it.

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 ...
