Thread: Getting list of held lwlocks from debugger
Is there an easy way to get a list of held lwlocks out of gdb attached to a core dump (or for that matter attached to a live process)?
I can try manually walking the internal data structure, but I am hoping for something analogous to the way you get memory contexts:
Cheers,

There's the held_lwlocks array in lwlock.c, but that will just give you pointers. What I imagine you're wishing for is some symbolic display of which locks they are, and I see no code for that. The "lock tranche" infrastructure that Robert's been working on would allow for reasonably decent printout, but it's not complete yet ... regards, tom lane
