Make amalgamtion the default when building. This way we can support fewer build configurations. Also, remove all undefined behavior due to use of memcpy with NULL pointers. GCC was exploiting this to remove NULL checks in some builds.

typedef struct JanetScratch JanetScratch;
Use make-image-dict and load-image-dict in thread/new Rather than messing with janet_core_dictionary, we instead cache the core enevironment, and pull out the needed tables from there. This is more flexible, more correct, and also exposes janet_resolve_core, which can be easily used from the C API.

extern JANET_THREAD_LOCAL JanetFiber *janet_vm_fiber;
Working TCP echo server and client. Required a few changes to APIs, namely janet_root_fiber() to get topmost fiber that is active in the current scheduler. This is distinct from janet_current_fiber(), which gets the bottom most fiber in the fiber stack - it might have a parent, and so cannot be reliably resumed. This is the kind of situation that makes symmetric coroutines more attractive.

2018-05-14 13:55:34 +00:00
Experimental changes to janet_call to make it faster. Remove setjmp and fiber creationg from janet_call. This adds the constraint to janet_call can only be called when there is already a current fiber.

Make janet_equals and janet_compare non recursive This makes these operatios use constant stack space rather than linear stackspace given the size of the inputs. This is important to prevent certain parser input from causing a stack overflow - in general, we try to avoid unbounded recursion.
