Using ActiveMQ fileQueueCursor and the temp store without enabling persistence -


i'm using activemq 5.7.0 , want filequeuecursor spill temp store if queue destination reaches memory threshold. don't want enable persistence.

i've configured destinationpolicy:

    <destinationpolicy>         <policymap>             <policyentries>                 <policyentry queue=">">                       <pendingqueuepolicy>                         <filequeuecursor />                     </pendingqueuepolicy>                 </policyentry>             </policyentries>         </policymap>     </destinationpolicy>

i've configured systemusage low memoryusage testing:

    <systemusage>         <systemusage>             <memoryusage>                 <memoryusage limit="5 mb" />             </memoryusage>             <tempusage>                 <tempusage limit="32 mb" />             </tempusage>         </systemusage>     </systemusage>

i have code running in debugger insert messages queue. while running can see messages increased memory usage:

2013-may-09 17:40:12.963 pdt debug [activemq transport: tcp:///127.0.0.1:63223@61616] [org.apache.activemq.usage.usage:fireevent] [usage.java:245] [] [] [] - default:memory:queue://testreq:memory: usage change from: 69% of available memory, to: 70% of available memory

i've noticed amq's filependingmessagecursor.flushtodisk() called @ around 70% memory usage because 'store' member null code not executed.

when enable persistence store not null , flushtodisk() completes.

is possible set temporary store without enabling persistence?

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
