i attempting re-organize our test libraries automation , nose seems promising. question is, best strategy passing python objects nose tests? our tests organized in testlib bunch of modules exercise different types of request operations. this: testlib \-testmoda \-testmodb \-testmodc in cases test modules (i.e. testmoda) nothing test_something(), test_something2() functions while in cases have testmodb class in testmob test_anotherthing1(), test_anotherthing2() functions. cool thing nose finds both. most of test functions request factory stuff can share single connection our server farm. lot of test_something1(cnn), testmodb.test_anotherthing2(cnn), etc. currently don't use nose, instead have hodge-podge of homegrown driver scripts hard-coded lists of tests execute. each of driver scripts creates own connection object. maintaining scripts , connection minutia painful. i'd take free advantage of nose's beautiful discovery functionality, passing in connec...

after stripping down code minimum, still not work. alway hint: (hidden field id) select valid choice. choice not 1 of available choices. this forms looks like: class changeitemform(forms.modelform): def __init__(self, *args, **kwargs): super(changeitemform, self).__init__(*args, **kwargs) key in self.fields: self.fields[key].required = false class meta: model = item fields = ('name','tags','no') changeitemformset=modelformset_factory(item,extra=0,form=changeitemform) and view looks this: def manage_view(request): if request.method=='post': itemforms=changeitemformset(request.post, queryset=item.objects.filter(creator=request.user)) else: itemforms=changeitemformset(queryset=item.objects.filter(creator=request.user)) messages.info(request,str(itemforms.is_valid())) #always prints false context=requestcontext(request)...

in sl4 lob app, i’ve hit f5 1000x or more no problems. suddenly, hitting f5 can take 90 seconds before app’s startup event raised. i’ve tried clearing ie browsers cache, no there. i created new navigation app no code whatsoever, hit f5, started immediately, great. began adding same assembly references sl4 lob app newly created navigation app. after each reference added, hit f5 ensure app able startup immediately; far good. alas, came system.windows.controls.data.toolkit.dll caused same behavior original sl4 lob app. removed reference navigation app, , again, start immediately. it’s 33kb, can’t argue i’m having problems symbol cache. has else seen strange behavior? insight appreciated. the small size of app not matter how debugging sessions starts up. slowdown caused large number of dependencies in application. you did remove single reference improved things tremendously , chances single dll dependent on dozens of other libraries. if check process tool process...

i'm going building library processing , generating syncml messages (syncml = xml protocol syncing contacts , calendars), , i'd able port , use library on many devices possible (mac, pc, iphone, android, blackberry, windows phone 7), because logic going same, , don't want spend time on re-building native library each platform. my question is: technologies , programming languages should getting done? java, c , c++ spring mind, , colleague has suggested lua. i'd so's opinion on before start working on it. my background c#/.net, objective-c, , java. any information welcome. thank you! why reinvent wheel? java has runtime environment mac, pc, linux, android, blackberry, , windows mobile. unfortunately popular option, iphone, has propriatary coding platform , can't run java. java has done hard work in writing cross-platform runtime environment. careful version of java platform use though, mobile devices may not support newest se yet. with ob...

let's have 2 folders in php server root directory: "x" , "y". but, in "x" directory there 2 more directories: "a" , "b"! in "/x/a" directory have "index.php" file , in "/y" folder have "stuff.php" file. "/x/a/index.php" file, want include "/y/stuff.php" file! how do that? server doesn't allow including files other domains, adding full url doesn't work! also, i'd know how start path root in php. use "./blabla" index of root , "../blabla" directories in root, but, unfortunately, ".../blabla" doesn't work 2nd grade directories. to access root begin path "/". if want go 1 directory currently, e.g. /x/a/ /x/ use "../". if want go 2 directories (e.g. /x/a/ /) use "../../" (rather ".../" mentioned).

so have panel class. it's little window can resize, close, add buttons, sliders, etc. status screen in morrowind if of remember. behavior want when sprite outside of panel's bounds doesn't drawn , if it's partially outside part inside gets drawn. right first rectangle represents bounds of panel, , rectangle sprite, finds rectangle of intersection between 2 translates intersection local coordinates of sprite rectangle , uses that source rectangle. works , clever feel code can't shake feeling there's better way this. also, set cannot utilize global transformation matrix 2d camera, in "world" must passed camera argument draw. anyway, here's code have: intersection: public static rectangle? intersection(rectangle rectangle1, rectangle rectangle2) { if (rectangle1.intersects(rectangle2)) { if (rectangle1.contains(rectangle2)) { return rectangle2; } el...

assume have application, user can provide script written in javascript perform task in it. done using jint. however, badly written script can cause stack overflow exception in jintengine.run() , therefore crashing whole application. rather inform user error in script. i tried run jint on application domain, did not help, cause afaik default action on soe exiting process. changed other way using clr hosting? i know can run separate process , that's fallback, nevertheless not that. as suspected, it's not possible catch stackoverflowexception generated runtime unless you're hosting clr [1]. microsoft documentation suggests, best bet try , detect stack overflow before happens. in case of using jint, means finding way hook execution engine , attach own code arbitrary method calls. fortunately, brief overview of documentation reveals have debugging mode that! [2] no doubt running in debugging mode means slowing down script execution; it's decide if benef...

how resize (and change possition) of window of other application programically? code java, , want resize windows, not created jvm. i'm using windows xp. change other properties of windows if there more options. additional information after comments: q: why want that? a: windows lacks feature move window across multiple displays fast . have tried winsplit revolution 9.02? has great features move/position window few button presses. don't need grab mouse @ all. the way windows not own in pure java java.awt.robot class. not offer useful api goal, screenshot, analize results, , position, press, move , release mouse accordingly - thus, same human user do. if want more, have system-specific. think both windows api , x protocol (ant x client libraries) offer @ least ability informations other program windows, don't know changing them. (i suppose mac os has such capabilities, too.) this mean writing @ least basics of functionality in c (or other language acces...

let's you're transferring file of arbitrary length in chunks on tcp/ip: looping... read(buffer, length) send(mysocket, buffer, length, flags) my question is, optimal value of length? or not matter @ all? i've seen 256 bytes 8192 bytes being used. depends mean optimal. optimal usage of bandwidth, want maximize packet size send @ least network packet size (which on ethernet 1500 bytes). if reading disk 4096 or 8192 bytes value.

i implementing ios decryption code message originating on server on have no control. previous implementation on platform documents decryption requirements aes256, specifies key , initialization vector, , says: * cipher mode: cbc * padding: pkcs5padding the options creation of cccryptor object include kccoptionpkcs7padding , kccoptionecbmode, noting cbc default. what understand padding encryption, don't understand how 1 might use both; thought mutually exclusive. in creating cccryptor decryption, have tried using both 0 options , kccoptionpkcs7padding, both give me gibberish after decryption. i have compared dump of decryption dump of decoded byte buffer on other platform , confirmed different. there doing different in implementation different, don't know what... , don't have clue how handle on it. platforms different enough difficult infer previous implementation because based on different platform. , of course, author of previous implementation has since...
