5996477a5e out-of-memory handling in packrat backend 2015-11-30 18:01:23 +01:00

3fc56a0dc3 add h_alloc() which calls errx() on failure and use it for all basic allocation
Rationale: "Basic allocation" refers to things outside of parsing proper,
mostly initialization. If such allocations fail, the system is globally
emory-starved from which it will likely not recover by returning failure.
In this case, terminating the process is in fact the most robust strategy as
it may mean the difference between a permanent hang and a temporary crash.

ca1d8df06c don't allocate a new arena in h_bind, use the existing one
Rationale: If memory allocation fails in the inner parse and we
longjump up the stack, the temporary arena will be missed and leak.

NB: This change means that any allocations done by the continuation
(in the form of new parsers, probably) will persist for the
lifetime of the parse result. Beware of wasting too much memory
this way! The bind continuation should generally keep dynamic
allocations to a minimum.
