dc14a68162 fix performance problem in expander 
For a term

 (lambda (arg-id ...) (define def-id _rhs) ... (arg-id def-id) ...)

the expander could take quadratic time in the number of `def-id`s
due to walking an environment to remove use-site scopes. (The
variant of the expander rewritten in Racket didn't have this
problem.)

ff26c2f29b fix complexity of type merging in bytecode optimizer 
Merge a smaller table into a larger one to avoid an overall
quadratic-time computation.

5c27f5550c Add mzrt_sema_trywait to the mzrt library. 
This commit add mzrt_sema_try_wait to the functions that operate
on semaphores. The existing ones are:

* int mzrt_sema_create(mzrt_sema **sema, int init);
* int mzrt_sema_post(mzrt_sema *sema);
* int mzrt_sema_wait(mzrt_sema *sema);
* int mzrt_sema_destroy(mzrt_sema *sema);

Add documentation for scheme_atexit 2017-06-04 18:52:09 -04:00
Leif Andersen
5510a76dca
scheme_add_atexit_closer now uses scheme_atexit. 
This is because calling atexit is not correct in all
situations, namely on old operating systems.

Add scheme_atexit c function. 
This way programs can actually call atexit. (Otherwise atexit
is frequently not provided in libc as a symbol.)

2f6c42f3c1 Add a #:make-c-id flag to define-ffi-definer 
This make-c-id allows an author to specify a convention for how
to connect and identifier defined with define-ffi-definer and
the actual symbol in the file.

* Adds docs.
* Adds tests.
* Adds history.

comparing it cblock->list.

restore/move tests in "file.rktl" test suite; and add docs for new
functions.

87c0ca84a8 add ffi/unsafe/global and switch openssl to use it 
Continues the move away from using the FFI to access unsafe Racket
functionality.

bf83d1126d add some unsafe operations as an alternative to FFI access 
Accessing unsafe functionality through the FFI seemed like a good way
to avoid writing C code, but it made things more complicated instead
of easier, and it interacts badly with a more agressive shift away
from C (such as porting to Chez Scheme). So, add functions to the
primitive `#%unsafe` module, instead.

ctype -> ctype? 
Also void -> void?

These two forms are now documented using contracts, which matches
with the rest of the FFI docs.

On Linux, munmap can fail when you run out of mappable regions.

If protect_pages fails, then you can't install a write barrier

f43234e1cb add prop:authentic and (struct .... #:authentic ....) 
An authentic structure type is one whose instances cannot be
impersonated or chaperoned. The intended use of `prop:authentic` is to
annotate a library-private data structure where impersonators are
never needed internally for the data structure, and the declaration
lets the compiler produce less code and fewer branches by omitting
impersonator support.
