Multithreading use of python scripts in c++ -


i'm using code python multithreading scripts (got web):

class pymainguard { public: pymainguard() {     py_initialize();     pyeval_initthreads();     mgilstate = pygilstate_ensure();     mthreadstate = pyeval_savethread(); }  ~pymainguard() {     pyeval_restorethread( mthreadstate );     pygilstate_release( mgilstate );     py_finalize(); }  private: pygilstate_state mgilstate; pythreadstate* mthreadstate; };  class pythrguard { public: pythrguard() {     mmaingilstate = pygilstate_ensure();     moldthreadstate = pythreadstate_get();     mnewthreadstate = py_newinterpreter();     pythreadstate_swap( mnewthreadstate );     msubthreadstate = pyeval_savethread();     msubgilstate = pygilstate_ensure(); }  ~pythrguard() {     pygilstate_release( msubgilstate );     pyeval_restorethread( msubthreadstate );     py_endinterpreter( mnewthreadstate );     pythreadstate_swap( moldthreadstate );     pygilstate_release( mmaingilstate ); }  private: pygilstate_state mmaingilstate; pythreadstate* moldthreadstate; pythreadstate* mnewthreadstate; pythreadstate* msubthreadstate; pygilstate_state msubgilstate; };

in main thread need create pymainguard, , in every single thread have create pythrguard - creates there independent interpretator, allows me use threading without problem. still share same resources.

for example, if use scrypts:

import win32evtlog import time  server = "localhost" logtype = "testeventsource" archfile = "c:\test.txt"  eventlog_success = 0  hwritelog = win32evtlog.registereventsource(none, logtype.decode('unicode-escape'))  strings = []  x in range(0, 5):     del strings[:]     y in range(0, 3):         = "python run [%d] part %d" % (x, y)         strings.append(a.decode('unicode-escape'))         time.sleep(2)     win32evtlog.reportevent(hwritelog, eventlog_success, 0, 515, none, strings, none)  win32evtlog.deregistereventsource(hwritelog)

sometimes can crash, there can created events in windows log more or less 3 lines of text (i.e. different threads write 1 event, having same eventhandle, guess).

everything looks threads still works in same interpeter, not in different ones. or there chance win32evtlog thread unsafe, loads ones (not every interpreter, want) , creates such problems.

question is: how achieve different interpreters each thread?
