Hi,
If my understanding is correct, current gdb checkpoint/restart is using
fork() and does not support multi-threading.
I am interested to know if someone has done some work to integrate BLCR
(Berkely Lab Checkpoint/Restart ,
https://ftg.lbl.gov/CheckpointRestart/CheckpointRestart.shtml) into gdb?
As a standalone, BLCR is quite helpful in certain debugging scenarios. But
it is a bit hard to use with gdb , i.e. breakpoints can not be saved and
restart is not convienent to stop at certain point etc.
BLCR's limitation is it is only for Linux x86 and x86_64. It also needs to
load kernel modules which may or may not be an issue. It is not targeting
debugging but rather process management/fault tolerance.
Thanks,
Zhiyong
