I'm very interested in developing a module for lua (or io), mostly for testing the best possible integration with the Nginx event module.
I'd like to see Lua as a replacement/alternative for Nginx's Perl module. Unlike most dynamic languages, Lua was originally designed to be embedded. I find its syntax much cleaner than Perl and it undoubtedly has a much smaller memory footprint.
I prefer nekovm (http://www.nekovm.org/) for this ;-)
Look:
http://lists.motion-twin.com/pipermail/neko/2008-April/thread.html
=> NGinx and NekoVM
It seems that Neko as well as Lua, perl, etc do the same in memory allocation failure case: exit() or nothing, i.e., segfault.
From what I can see, Lua (as Python) throws an exception in case of
memory allocation failure.
Python uses a statically allocated object for the Memory Error exception.
Lua uses _longjmp/_setjmp, with integer representing error codes. It only calls exit if no exception handler is installed.
Well, but what can I do in exception handler ? Destroy a whole interpreter, leaving various leaks ?
With Lua you can supply you allocator function.
It does not resolve the problem. The interpreter internally must test result of EVERY function that may fail on memory allocations:
void * interpreter_function0() { p = interpreter_function1(); if (p == NULL) { some rollback operations return NULL; } }
