i have large long-running server, and, on weeks memory usage steadily climbs. generally, pointed out below, unlikely leaks problem; however, have not got lot go on want see if there leaks. getting @ console output tricky i'm not running gc.set_debug() . not big problem though, have added api run gc.collect() , iterate through gc.garbage , send results out me on http. my problem running locally short time gc.garbage empty. can't test bit of code lists leaks before deploy it. is there trivial recipe creating uncollectable bit of garbage can test code lists garbage? any cycle of finalizable objects (that is, objects __del__ method) uncollectable (because garbage collector not know order run finalizers in): >>> class finalizable: ... def __del__(self): pass ... >>> = finalizable() >>> b = finalizable() >>> a.x = b >>> b.x = >>> del >>> del b >>> import gc >>> gc.collect...

if have used collection in class may instantiated many times, may resort following "idiom" in order save unnecessary object creations: list<object> list = null; void add(object object) { if (list == null) list = new arraylist<object>(); list.add(object); } // somewhere else if (list != null) (object object : list) ; now wondering if couldn't eliminate null checks using collections.emptylist() , have alter if check in add() so: if (list == collections.<object>emptylist()) list = new arraylist<object>(); is there better way handle other allocating new empty collection every time? edit: clear, would like use collections.emptylist(), above check in add() really ugly... wondering if there's better way or whole other way of handling this. in order save unnecessary object creations that's bad idea litter code == null checks , other handling of corner cases (and presumably end in ...

i changing applications tooltips use balloonhints. test using single line , displayed nicely. when hint text multi-line (i.e existing hints ... 'this test' + #13 + 'hello'+ #13 + 'hello'+ #13 + 'hello'+ #13 + 'hello' when displayed in balloonhint, size wrong , whole list of entries offset disappear. anyone got helpful suggestions ? update: seems title messes display up. i'll report in qc. so knew if put #13#10 properties inspector that's putting characters literally string. way instead: procedure tform2.formcreate(sender: tobject); begin button1.hint := 'this test' + #13 + 'hello'+ #13 + 'hello'+ #13 + 'hello'+ #13 + 'hello'; end; when try in delphi xe, looks fine me. tms's hint component nicer -- if can switch else, try that. try tjvballoonhint in jvcl.

i use windows. example have website structure smth this: site/ engine/ modelclass.php www/ index.php tests/ modelcalsstest.php phpunit.bat where should store phpunit.bat run test modelclasstest.php? you should not need store phpunit.bat @ all. should in path . just install via pear , done. if don't want , have locally on system or want phpunit sources in version control (some people want that) doesn't matter phpunit.bat really. project root fine, somewhere in vendor/phpunit/phpunit.bat fine if have ant or phing or .bat file in project root lets "run tests now" . what observe "best-practice" put phpunit.xml.dist (the config file) in application root people can just: get source type phpunit see works see: a sample project made phpunit author what i've seen people put config file in "tests" folder have "clean project root". works out nicely. references: documentation...

i need write application takes string input. after processing, should print out string reversed, , characters switched lower uppercase , vise versa. want achieve using stringbuilder . sample run: input: hello human output: namuh olleh here straight forward , simple way of solving problem: read user input using instance scanner class. , nextline() method. (construct scanner giving system.in argument.) create stringbuilder . fetch array of characters input string, using instance input.tochararray() reverse array arrays.aslist , collections.reverse collections.reverse(arrays.aslist(yourchararray)); loop through list using instance for-each loop. for (character c : yourchararray) { ... } for each character, check if c.isuppercase (if append c.tolowercase() ) else append c.touppercase() . (an alternative approach give stringbuilder input-string argument, , manipulate string in-place using reverse , charat , setcharat methods.)

i've got setup use doxygen describe set on unit tests (i use qttest run tests). output tests parsed little python snippet produces nice , tidy report. now, i'd love link report each test case, i.e. private slot member method, in doxygen material. however, anchors defined doxygen looks this: <a class="anchor" id="a2a0e066d4dad8e0dff6c9231bf65fd65"></a> <!-- doxytag: member="pradiotunertst::scanfm" ref="a2a0e066d4dad8e0dff6c9231bf65fd65" args="()" --> sure, parse doxygen html , match method reference key, i'd rather have readable links. not overload unit test case methods, having them enumerated not issue - i'd able pick first , only. i'd happy calculate id hash myself. need know how to. so, basically, questions is: does know how tune doxygen generate readable anchors if not, how calculate hash? instead of trying reconstruct hash (which md5 checksum on method's definition ...

i'm building application recording audio microphone, whenever audio reaches threshold perform action. however how should calc appropriate volume threshold ? i've static volume coded works across devices not devices (in somes cases sensitive or vice versa). i'm using audiorecord, here's part of code: int buffersize = audiorecord.getminbuffersize(constants.recording_frequency,constants.channelconfiguration,constants.audioencoding); audiorecord audiorecord = new audiorecord( mediarecorder.audiosource.mic,constants.recording_frequency,constants.channelconfiguration,constants.audioencoding, buffersize); short[] buffer = new short[buffersize]; while(true) { int bufferreadresult = audiorecord.read(buffer, 0, buffersize); (int = 0; < bufferreadresult; i++) { currentvolume = java.lang.math.abs(buffer[i]); if (currentvolume > constants.no_volume_amplitude) // alright ! i'm looking :d } } so, question is: how calculate consta...
