android - OSError: [Errno 2] No such file or directory when running systrace.py -

-

i'm trying run systrace python script included in platform-tools folder , i'm getting following error:

file "systrace.py", line 274, in <module>  main() file "systrace.py", line 60, in main  device_sdk_version = get_device_sdk_version() file "systrace.py", line 44, in get_device_sdk_version  stderr=subprocess.pipe) file "/usr/lib/python2.7/subprocess.py", line 679, in __init__  errread, errwrite) file "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child  raise child_exception oserror: [errno 2] no such file or directory

i'm running on ubuntu 12.04 lts. here command i'm using run systrace:

sudo python systrace.py -o output.html

note: sudo in order avoid following error:

file "systrace.py", line 274, in <module>  main() file "systrace.py", line 63, in main  os.execv(legacy_script, sys.argv) oserror: [errno 13] permission denied

after doing searching around web found 1 solution add adb path variable. added platform-tools directory path , i'm still getting same error. went ahead check code causing problem , apparently snippet:

adb = subprocess.popen(getprop_args, stdout=subprocess.pipe,                      stderr=subprocess.pipe)

where getprop_args defined follows:

getprop_args = ['adb', 'shell', 'getprop', 'ro.build.version.sdk']

from understand code trying run following command:

adb shell getprop ro.build.version.sdk

i ran command in console , work no problem. copied both lines of code , ran them in python interpreter , ran without problem. don't know how solve issue. know of possible solution?

ok found out problem was. problem sudo putting right before python systrace.py -o output.html didn't know guess path variable different when using sudo, when not using it. path in sudo didn't have platform-tools directory. removed sudo , getting following error: 

file "systrace.py", line 274, in <module>  main() file "systrace.py", line 63, in main  os.execv(legacy_script, sys.argv) oserror: [errno 13] permission denied

to solve problem ran following command on legacy_script:

$chmod +x ./systrace-legacy.py

and able run systrace script without problem :p

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
