SigInfoPDB class

class siginfo.siginfoclass.SigInfoPDB(info=True, usr1=True, usr2=False, output=None)[source]

Bases: SiginfoBasic

SigInfo class that starts the Python PDB Debugger

Instead of printing out the call stack, it allows to interactively inspect the current frame via PDB Debugger.

Local variables from current frame are avaialable via the _locals dict.

Example

foo = SigInfoPDB()
do_long_task()

# create executeable to send signal to Python script
foo.create_info_script('/usr/local/bin')

Now get access to PDB debugger in another terminal window:

# send signal via custom script
/usr/local/bin/siginfo-USR1
create_info_script(path=None, prefix='', overwrite=False)

Create an executable on the file system to send the appropiate signal.

For user convenience, create executable filess in the specified path that can be used to send corresponding signals to the parent’s script.

Parameters:

  • path (str) – path to executable files (default $HOME)

  • prefix (str) – Prefix of the executable file name (default ‘’)

  • overwrite (bool) – Overwrite existing executables (default False)

Return type:

None
