gdb: Auto-loading

 
 22.8 Automatically loading associated files
 ===========================================
 
 GDB sometimes reads files with commands and settings automatically,
 without being explicitly told so by the user.  We call this feature
 "auto-loading".  While auto-loading is useful for automatically adapting
 GDB to the needs of your project, it can sometimes produce unexpected
 results or introduce security risks (e.g., if the file comes from
 untrusted sources).
 

Menu

 
· Init File in the Current Directory 'set/show/info auto-load local-gdbinit'
· libthread_db.so.1 file             'set/show/info auto-load libthread-db'
 
· Auto-loading safe path             'set/show/info auto-load safe-path'
· Auto-loading verbose mode          'set/show debug auto-load'
 
    There are various kinds of files GDB can automatically load.  In
 addition to these files, GDB supports auto-loading code written in
 various extension languages.  Auto-loading extensions.
 
    Note that loading of these associated files (including the local
 '.gdbinit' file) requires accordingly configured 'auto-load safe-path'
 (Auto-loading safe path).
 
    For these reasons, GDB includes commands and options to let you
 control when to auto-load files and which files should be auto-loaded.
 
 'set auto-load off'
      Globally disable loading of all auto-loaded files.  You may want to
      -init-eval-command::) such as:
           $ gdb -iex "set auto-load off" untrusted-executable corefile
 
      Be aware that system init file (System-wide configuration)
      File::) still get read (as they come from generally trusted
      directories).  To prevent GDB from auto-loading even those init
      files, use the '-nx' option (Mode Options), in addition to
      'set auto-load no'.
 
 'show auto-load'
      Show whether auto-loading of each specific 'auto-load' file(s) is
      enabled or disabled.
 
           (gdb) show auto-load
           gdb-scripts:  Auto-loading of canned sequences of commands scripts is on.
           libthread-db:  Auto-loading of inferior specific libthread_db is on.
           local-gdbinit:  Auto-loading of .gdbinit script from current directory
                           is on.
           python-scripts:  Auto-loading of Python scripts is on.
           safe-path:  List of directories from which it is safe to auto-load files
                       is $debugdir:$datadir/auto-load.
           scripts-directory:  List of directories from which to load auto-loaded scripts
                               is $debugdir:$datadir/auto-load.
 
 'info auto-load'
      Print whether each specific 'auto-load' file(s) have been
      auto-loaded or not.
 
           (gdb) info auto-load
           gdb-scripts:
           Loaded  Script
           Yes     /home/user/gdb/gdb-gdb.gdb
           libthread-db:  No auto-loaded libthread-db.
           local-gdbinit:  Local .gdbinit file "/home/user/gdb/.gdbinit" has been
                           loaded.
