handles returned by CreateFileA and FILE_FLAG_OVERLAPPED
support reading from arbitrary offsets.
The offset is passed to ReadFile in through the OVERLAPPED structure.
Since state->overlapped is zeroed ev_machine_read
ReadFile would always read from the start of the file and never finish
This commit changes ev_machine_read to update the offset to
the number of bytes read before calling ReadFile.
- Change the global binding name from :redefs to :redef
- Simplify internal representation of "redefinable bindings"
- Store "redefinable bindings in :ref rather than :value inside the
environment entries. This makes such bindings more like vars that
can't be set rather than defs.
Rather than manual reference counting for suspended fibers, we
automate the process by incrementing "extra_listeners" every time
we suspend a fiber in the event loop, and decrement when that fiber
is resumed. In this manner, we keep track of the number of suspending
fibers in a simpler, more correct way.
Try to have better behavior when mixing sub-hashes that are not uniform and
randomly distributed. Premultiply by a large prime before mixing to
"spread entropy" if it is concentrated in a certain subset of bits.
This doesn't destory the pid until the original thread decides to
call waitpid again. Since the pid is exposed in the C API and now
in the Janet API, we don't want to destroy it until we are ready.
This at least means users can use something like jsys
or the kill command to signal processes when they want
to send unsupported signals (like SIGTERM).
We were casting a pointer to the wrong type, which caused all sorts of
wonderful chaos, but only on windows and only when the garbage collector
ran after setting up a server in a specific configuration. We were
casting a closure pointer to an abstract type during the mark phase,
which resulted in memory corruption.
We did not allow arbitrary utf8 to be printed with %j, even though the parser
allows. Thos changes uses the existing built in utf8 detectiotion to
exclude only unprintable symbols from the docstring.
