From 93c3f2a0b4da77c0317496b8585192fb64ef400f Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Thu, 24 Oct 2024 11:59:32 +0200 Subject: [PATCH] MINOR: debug: place the post_mortem struct in its own section. Placing it in its own section will ease its finding, particularly in gdb which is too dumb to find anything in memory. Now it will be sufficient to issue this: $ gdb -ex "info files" -ex "quit" ./haproxy core 2>/dev/null |grep _post_mortem 0x0000000000cfd300 - 0x0000000000cfe780 is _post_mortem or this: $ objdump -h haproxy|grep post 34 _post_mortem 00001480 0000000000cfd300 0000000000cfd300 008fc300 2**8 to spot the symbol's address. Then it can be read this way: (gdb) p *(struct post_mortem *)0x0000000000cfd300 --- src/debug.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/debug.c b/src/debug.c index 6e5148e30..fb4d7847f 100644 --- a/src/debug.c +++ b/src/debug.c @@ -156,7 +156,7 @@ struct post_mortem { */ uint nb_components; // # of components below struct post_mortem_component *components; // NULL or array -} post_mortem ALIGNED(256) = { }; +} post_mortem ALIGNED(256) HA_SECTION("_post_mortem") = { }; unsigned int debug_commands_issued = 0;
