I am seeing apr_hash_set calls expand_array.
expand_array core dumps if memory can not be allocated.
Is this expected? Is there a way to get an error code for a failed
insert
to a table rather than a coredump?
This is definitely wrong, APR should return APR_ENOMEM if memory
cannot be allocated.
More specifically, the APR pools code gives the caller (you) the
choice of behaviour when the memory allocation fails. You can choose
to have APR call a function of your choice, or you can choose APR to
return APR_ENOMEM.
httpd chooses to call a function that terminates the server child when
out of memory, and as a result httpd makes no attempt to cater for out
of memory conditions, but other callers of APR don't have to, and APR
itself should definitely respect APR_ENOMEM.
