Simon Tatham	4262ce45ca	gdb.py: support functions for container_of and tree234. The gdb version of container_of can do better than the C function, because you don't have to specify the structure field name if it can be inferred from the type of the input expression. And $list234 can be made to automatically list the contents of each tree element, not just a pointer to it - just the thing for looking quickly through sktree or s->channels to find the one you're after.	2018-11-16 19:22:43 +00:00
Simon Tatham	734ada9b57	gdb.py: add a 'memdump' command. This makes it easier for me to examine the contents of binary memory buffers, while debugging through code that does crypto or packet marshalling.	2018-06-09 14:20:33 +01:00
Simon Tatham	10a4f1156c	Add a GDB Python script to pretty-print Bignum. I've been playing around with GDB's Python scripting system recently, and this is a thing I've always thought it would be nice to be able to do: if you load this script (which, on Ubuntu 18.04's gdb, is as simple as 'source contrib/gdb.py' at the gdb prompt, or similar), then variables of type Bignum will be printed as (e.g.) 'Bignum(0x12345)', or 'Bignum(NULL)' if they're null pointers, or a fallback representation if they're non-null pointers but gdb can't read anything sensible from them.	2018-06-04 19:10:57 +01:00

The gdb version of container_of can do better than the C function,
because you don't have to specify the structure field name if it can
be inferred from the type of the input expression.

And $list234 can be made to automatically list the contents of each
tree element, not just a pointer to it - just the thing for looking
quickly through sktree or s->channels to find the one you're after.

gdb.py: add a 'memdump' command.

This makes it easier for me to examine the contents of binary memory
buffers, while debugging through code that does crypto or packet
marshalling.

Add a GDB Python script to pretty-print Bignum.

I've been playing around with GDB's Python scripting system recently,
and this is a thing I've always thought it would be nice to be able to
do: if you load this script (which, on Ubuntu 18.04's gdb, is as
simple as 'source contrib/gdb.py' at the gdb prompt, or similar), then
variables of type Bignum will be printed as (e.g.) 'Bignum(0x12345)',
or 'Bignum(NULL)' if they're null pointers, or a fallback
representation if they're non-null pointers but gdb can't read
anything sensible from them.
