Are Spring Batch 3 database structure changes compatible with Spring Batch 2? -


we migrated spring batch 2.1.7 spring batch 3.0.6, got jboss startup error:

org.springframework.jdbc.badsqlgrammarexception: preparedstatementcallback; bad sql grammar [select e.job_execution_id, e.start_time, e.end_time, e.status, e.exit_code, e.exit_message, e.create_time, e.last_updated, e.version, e.job_instance_id, e.job_configuration_location batch_job_execution e, batch_job_instance e.job_instance_id=i.job_instance_id , i.job_name=? , e.end_time null order e.job_execution_id desc]; nested exception java.sql.sqlsyntaxerrorexception: ora-00904: "e"."job_configuration_location": invalid identifier

...which apparently caused spring batch 3 auto-migration, in spring batch 3 has table structure changes spring batch 2.

to things moving forward, using create table script our developer team found in 1 of spring batch jars, our dba team wrote script update (instead of create) tables, since need job history. working far, here our issue:

we can't migrate our systems forward spring batch 3. have leave older ones in spring batch 2 while.

are these spring batch 3 table structure changes backward compatible spring batch 2?

they appear analysis our dba team , our batch run results far, i'm asking if intentional spring, i.e. when spring altered table structure purposes of spring batch 3, did intentionally make backward compatible?

so far appear compatible, want make sure there isn't subtle difference break our system badly down not-often-used logic path, i.e. @ statement execution time (vs jboss startup time).

they not backwards compatible. way job parameters stored different. migration scripts did not remove old columns (just added net new). doesn't mean couldn't come schema works both versions (it looks that's have), our intent, identified breaking change when added non-identifying parameters.

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

jquery - Responsive Navbar with Sub Navbar -

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
