Why higher priority for my repository does not works in apt? -


according manual:

       note of caution: keyword used here "origin" can        used match hostname. following record assign high        priority versions available server identified        hostname "ftp.de.debian.org"             package: *            pin: origin "ftp.de.debian.org"            pin-priority: 999

source link: http://manpages.ubuntu.com/manpages/zesty/man5/apt_preferences.5.html

there outputs:

apt preference is:

# more /etc/apt/preferences.d/default_source_list.pref package: * pin: origin "ubuntu-repository.youseeu.com" pin-priority: 999

policy package mysql-server:

# apt-cache policy mysql-server mysql-server:   installed: (none)   candidate: 5.5.57-0ubuntu0.14.04.1   version table:      5.5.57-0ubuntu0.14.04.1 0         500 http://us-east-2.ec2.archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 packages         500 http://security.ubuntu.com/ubuntu/ trusty-security/main amd64 packages         999 https://ubuntu-repository.youseeu.com/ysu_ubuntu14/ trusty/main amd64 packages      5.5.35+dfsg-1ubuntu1 0         500 http://us-east-2.ec2.archive.ubuntu.com/ubuntu/ trusty/main amd64 packages

check how works:

check policies:

# apt-cache policy | head -n 20 package files:  100 /var/lib/dpkg/status      release a=now  999 https://ubuntu-repository.youseeu.com/ysu_ubuntu14/ trusty/main amd64 packages      release o=ysu_ubuntu14 trusty,a=trusty,n=trusty,l=ysu_ubuntu14 trusty,c=main      origin ubuntu-repository.youseeu.com  500 http://security.ubuntu.com/ubuntu/ trusty-security/universe translation-en  500 http://security.ubuntu.com/ubuntu/ trusty-security/main translation-en  500 http://security.ubuntu.com/ubuntu/ trusty-security/universe amd64 packages      release v=14.04,o=ubuntu,a=trusty-security,n=trusty,l=ubuntu,c=universe      origin security.ubuntu.com  500 http://security.ubuntu.com/ubuntu/ trusty-security/main amd64 packages      release v=14.04,o=ubuntu,a=trusty-security,n=trusty,l=ubuntu,c=main      origin security.ubuntu.com  500 http://us-east-2.ec2.archive.ubuntu.com/ubuntu/ trusty-updates/universe translation-en  500 http://us-east-2.ec2.archive.ubuntu.com/ubuntu/ trusty-updates/main translation-en  500 http://us-east-2.ec2.archive.ubuntu.com/ubuntu/ trusty-updates/universe amd64 packages      release v=14.04,o=ubuntu,a=trusty-updates,n=trusty,l=ubuntu,c=universe      origin us-east-2.ec2.archive.ubuntu.com  500 http://us-east-2.ec2.archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 packages

so, why package mysql-server downloaded host us-east-2.ec2.archive.ubuntu.com?

why higher priority repository ubuntu-repository.youseeu.com did not work?

several instances of same version of package may available when sources.list(5) file contains references more 1 source. in case apt-get downloads instance listed earliest in sources.list(5) file. apt preferences not affect choice of instance, choice of version. source link(your link): http://manpages.ubuntu.com/manpages/zesty/man5/apt_preferences.5.html

so first apt search available versions:

apt-cache policy mysql-server mysql-server: installed: (none) candidate: 5.5.57-0ubuntu0.14.04.1 version table:

 5.5.57-0ubuntu0.14.04.1 0     500 http://us-east-2.ec2.archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 packages     500 http://security.ubuntu.com/ubuntu/ trusty-security/main amd64 packages     999 https://ubuntu-repository.youseeu.com/ysu_ubuntu14/ trusty/main amd64 packages  5.5.35+dfsg-1ubuntu1 0     500 http://us-east-2.ec2.archive.ubuntu.com/ubuntu/ trusty/main amd64 packages

version 5.5.57 found in 3 sources, priority ignored according to:

in case apt-get downloads instance listed earliest in sources.list(5) file. apt preferences not affect choice of instance, choice of version.

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
