This is to better allow configuration on various, unknown compilers.
Previously, we hardcoded how thread local storage was specified for a
few different compilers, but we were not following and C standard. In
C11, there is a standardized storage specifier _Thread_local for this
storage class, however this is now deprecated in various C++ compilers
for a new keyword, confusingly. Janet also does not claim to require the
C11 standard, so for maximum flexibilty, the storage specifier must be
specified at configure time.
The function has more problems than initially expected, both on Posix
systems and on Windows. Given all the caveats, it is probably best not
to include. Any function that can obtain files can use os/open instead.
The standard FILE objects also will not work anyway, and different
operating systems have different work arounds.
Mutable keys are a minefield for comparisons, as resolving
equality require re-implementing a lot of the internal structures, as
well as dealing with multiple mutable keys that are in the same
equivalency class by deep=.
Simplifying the implementation to not resole mutable keys is much
simpler, faster, and has the benefit that deep= and deep-not= do not
need to allocate.
In the cross compilation case, we need to resolve our
dependencies on libc twice, once for the build machine and once for the
target machine. This includes pthreads, -libc, and android-spawn.
net/* API documentation was not consistent with the implementation. The
`ev/*` module documentation was, however. On timeout, all networking
function calls raise an error and do not return nil. That was the old
behavior.
Weak containers did not preserve their weakness when marshalled. This
fixes that for tables and arrays, as well as adds some tests for this.
Also exposes functions for creating weak tables in janet.h
This allows importing only selected bindings.
For example,
(import foo :only [bar baz])
(foo/bar) # works
(foo/buzz) # doesn't work, even if the foo module has a buzz
function.
