user, that is, one that doesn't have the I{Administrator} or

not running with elevation.

This library is shipped with the Debugging Tools for Windows, and it's
required to load debug symbols.
Normally you don't need to call this method, as WinAppDbg already tries
to load the latest version automatically - but it may come in handy if
the Debugging Tools are installed in a non standard folder.
Example::
from winappdbg import Debug
def simple_debugger( argv ):
# Instance a Debug object, passing it the event handler callback
debug = Debug( my_event_handler )
try:
# Load a specific dbghelp.dll file
debug.system.load_dbghelp("C:\\Some folder\\dbghelp.dll")
# Start a new process for debugging
debug.execv( argv )
# Wait for the debugee to finish
debug.loop()
# Stop the debugger
finally:
debug.stop()

Microsoft WinDbg.

method will provide a default one.
@type symbol_store_path: str or None
@param symbol_store_path: (Optional) Symbol store path to set.
@type remote: bool
@param remote: (Optional) Defines the symbol store path to set when the
C{symbol_store_path} is C{None}.
If C{True} the default symbol store path is set to the Microsoft
symbol server. Debug symbols will be downloaded through HTTP.
This gives the best results but is also quite slow.
If C{False} the default symbol store path is set to the local
cache only. This prevents debug symbols from being downloaded and
is faster, but unless you've installed the debug symbols on this
machine or downloaded them in a previous debugging session, some
symbols may be missing.
If the C{symbol_store_path} argument is not C{None}, this argument
is ignored entirely.
@type force: bool
@param force: (Optional) If C{True} the new symbol store path is set
always. If C{False} the new symbol store path is only set if
missing.
This allows you to call this method preventively to ensure the
symbol server is always set up correctly when running your script,
but without messing up whatever configuration the user has.
Example::
from winappdbg import Debug, System
def simple_debugger( argv ):
# Instance a Debug object
debug = Debug( MyEventHandler() )
try:
# Make sure the remote symbol store is set
System.fix_symbol_store_path(remote = True,
force = False)
# Start a new process for debugging
debug.execv( argv )
# Wait for the debugee to finish
debug.loop()
# Stop the debugger
finally:
debug.stop()
@rtype: str or None
@return: The previously set symbol store path if any,
otherwise returns C{None}. | 3.311931 | 3.367624 | 0.983462 |
