Raise minimum stack size in ndb code to be a uniform 32K (64K on 64-bit
|
|
platforms). This is in response to an episode where glibc needed 8K of
|
|
stack to run malloc(), resulting in ndbd crashing at launch. While that
|
|
was acknowledged to be a glibc bug (see bz #494631), byte-shaving here
|
|
isn't any better an idea than it is in the main mysql server.
|
|
|
|
Note: the request gets rounded up to at least PTHREAD_STACK_MIN, which
|
|
is 128K on PPC; otherwise we would need to do something about including
|
|
the stack guard size explicitly, since it's so much larger on PPC than
|
|
elsewhere. At some point we might want to use our my_setstacksize()
|
|
hack in NdbThread_Create().
