java - logback RollingFileAppender not rolling files -


i have logback config having rollingfileappender appender sizeandtimebasedrollingpolicy. however, seems whenever application runs logback doesn't roll files , keeps appending same file on , on again.

my application executes little time not more few seconds. thought issue used cleanhistoryonstart option not working. please me.

here's config

<?xml version="1.0" encoding="utf-8"?> <configuration scan="true" scanperiod="20 seconds">   <appender name="consoleappender" class="ch.qos.logback.core.consoleappender">     <encoder>       <pattern>[%d{yyyy-mm-dd hh:mm:ss}] :: %-5p :: %-10class{0}:%l - %m%n</pattern>     </encoder>   </appender>   <appender name="processlogfileappender"  class="ch.qos.logback.core.rolling.rollingfileappender">         <append>true</append>         <file>/home/elkapp/etl_logs/etllogsgenerator/logs/etllogsgenerator.log</file>         <rollingpolicy class="ch.qos.logback.core.rolling.sizeandtimebasedrollingpolicy">                 <filenamepattern>/home/elkapp/etl_logs/etllogsgenerator/logs/etllogsgenerator-%d{yyyy-mm-dd}.%i.log</filenamepattern>                 <maxhistory>30</maxhistory>                 <maxfilesize>10mb</maxfilesize>                 <totalsizecap>500mb</totalsizecap>                 <cleanhistoryonstart>true</cleanhistoryonstart>         </rollingpolicy>         <encoder>                 <pattern>[%d{yyyy-mm-dd hh:mm:ss}] :: %-5p :: %-10class{0}:%l - %m%n            </pattern>         </encoder>   </appender>    <logger name="com.ibm.etllogsgenerator" level="info">     <appender-ref ref="processlogfileappender"/>     <!--appender-ref ref="consoleappender"/-->   </logger>  </configuration>

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

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
