ios5 - Unable to download data in Background after 10 minutes? -


i working app in want download data in background. per apple multitasking guidelines, allowed download data 10 minutes.

in case, take more 10 minutes downloading file , downloading failed.

initial downloading request downloadviewcontroller below.

- (ibaction)performlargeupload:(id)sender {  [request cancel]; [self setrequest:[asiformdatarequest requestwithurl:[nsurl urlwithstring:@"http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_stereo.avi"]]];  // 149mb  [request setdownloaddestinationpath:[[nshomedirectory() stringbyappendingpathcomponent:@"documents"] stringbyappendingpathcomponent:@"big_buck_bunny_480p_stereo.avi"]];  [request settimeoutseconds:20]; [request setdownloadprogressdelegate:progressindicator]; [request setuserinfo:[nsdictionary dictionarywithobject:@"request1" forkey:@"name"]];  #if __iphone_os_version_max_allowed >= __iphone_4_0 [request setshouldcontinuewhenappentersbackground:yes]; #endif [request setdelegate:self]; [request setdidfailselector:@selector(uploadfailed:)]; [request setdidfinishselector:@selector(uploadfinished:)]; [request setallowresumeforfiledownloads:yes];  [request startasynchronous]; [resultview settext:@"downloading data..."];  }

in appdelegate, have put code when applicationdidenterbackground

- (void)applicationdidenterbackground:(uiapplication *)application  {  uiapplication  *app = [uiapplication sharedapplication]; uibackgroundtaskidentifier bgtask;  bgtask = [app beginbackgroundtaskwithexpirationhandler:^{     [app endbackgroundtask:bgtask];  }];  backgroundtimer=nil; backgroundtimer = [nstimer scheduledtimerwithtimeinterval:10 target:self  selector:@selector(keepalive) userinfo:nil repeats:yes]; }

how extend time background downloading??

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...
