I wrote this patch to address two problems:
1. if I do `mach run` from a directory other than $topsrcdir, $objdir, or
$objdir/dist/bin, then .gdbinit will not be loaded.
2. Debugging the firefox binary will never load the JS prettyprinters in any
case.
I believe this patch fixes other problems as well, such as .gdbinit_python not being found, and the gdbpp pretty-printers not getting loaded in various situations.
The main changes of this patch are:
1. Move .gdbinit into build/ (and $objdir/build/) to delay it from getting
loaded until the search path is configured.
2. Move libxul.so-gdb.py into the correct directory.
3. Use either libxul.so-gdb.py or js-gdb.py to configure the correct
search path then load .gdbinit, and have .gdbinit load all of the
pretty-printers (Gecko and JS).
4. Use a single preprocessed file to configure the source directory. Use
relative paths within the objdir for everything else.

# loader for .gdbinit file
|
|
|
|
# This file provides a guard against multiple inclusion. GDB command syntax is
|
|
# rather limited in that you cannot have a `documentation` command inside of an
|
|
# `if`. So we use a separate loader file that sources `.gdbinit` within the
|
|
# `if`.
|
|
|
|
# You may need to put an 'add-auto-load-safe-path' command in your
|
|
# $HOME/.gdbinit file to get GDB to trust this file. If your builds are
|
|
# generally in $HOME/moz, then you can say:
|
|
#
|
|
# add-auto-load-safe-path ~/moz
|
|
|
|
# Multiple include guard
|
|
if $_moz_gdbinit_loaded
|
|
# already loaded
|
|
else
|
|
set $_moz_gdbinit_loaded=1
|
|
|
|
source -s build/.gdbinit
|
|
|
|
# This requires $objdir to have been added to gdb's source directory search
|
|
# path. Normally this will be done by libxul.so-gdb.py or js-gdb.py.
|
|
source -s build/.gdbinit.py
