Calvin Rose b4ec168401 Address #950 - add defn suggestion on bad def. 
While generally we are not in the business of making a very chatty
compiler, this is a simple improvement that involves compiling
metadata before the binding, as well as adding a suggestion for `defn`
in case the compiler encounters an unexpected tuple.

 2022-03-06 13:11:08 -06:00
Ian Shehadeh bbb3e16fd1 int/to-bytes: return a buffer instead of a tuple 
Buffers make more sense for this function because one of their primary
use cases is working with bytes.
The tuple implementation was an array of floats,  which is less
performant and ergonomic for common operations. (i.e: bit manipulation)

Buffers also have the advantage they are mutable, meaning the user
can write ints to an existing buffer.

Ian Shehadeh 75845c0283 int/to-number: restrict input to JANET_INTMAX/MIN 
Previously int/to-number would fail if the input was outside
the range of an int32.
Because Janet numbers are doubles,
they can safely store larger ints than an int32.
This commit updates int/to-number to restrict the
value to the range of integers a double can hold, instead of an int32.

Ian Shehadeh 88db9751d7 add int/to-number: converts s64 and u64 to numbers 
(int/to-number value) converts an s64 or u64 to a number.
It restricts the value to the int32 range,
so that `int32?` will always suceeded when called on the result.

ev: Fix timeout pruning logic 2022-02-11 09:25:23 +02:00
Calvin Rose 2f068b91d8 Mark a fiber as a root fiber during scheduling, not resumption. 
This is more intuitive and avoids the possibilty of strange code
to resume or cancel a fiber after it was scheduled but before it was
entered for the first time.

Calvin Rose e64da8ede4 Update CHANGELOG.md 2022-02-09 22:31:27 -06:00
Calvin Rose a9f38dfce4 Address #920 - fiber cancellation can hang event loop. 
The main issue was cancellation of fiber using `cancel` rather than
`ev/cancel` could cause issues with the event loop internal ref count.
Since this is almost certainly bad usage (and is not something I want to
encourage or support), we will warn against trying to resume or error
fibers that have already been suspended or scheduled on the event loop.
The distinction between "task" fibers and normal fibers is now kept by a
flag that is set when a fiber is resumed - if it is the outermost fiber
on the stack, it is considered a root fiber. All fibers scheduled with
ev/go or by the event loop are root fibers, and thus cannot be cancelled
or resumed with `cancel` or `resume` - instead, use `ev/cancel` or
`ev/go`.

Calvin Rose a097537a03 Fix #919 - strange quasiquote behavior. 
Nested expression in the quasiquote were being compiled with the "hint"
flag passed to the expression compilation, essentially telling the
compiler to put intermediates into the final slot, possibly overwriting
other intermediate values. This fix removes that flags on any recursive
calls to quasiquote.

Ian Shehadeh 4118d581af error if '& is followed by 2+ items in destructure 
The current destructure pattern ends when '& is encountered.
This commit adds an error if it is followed by more than
a symbol to bind the array to.

Although its not critical since the extra items can be ignored,
they're a sign of some kind of mistake so its best to complain.

Ian Shehadeh 62608bec03 use janet_checktype over janet_type and == 
In destructure janet_type(_) == JANET_SYMBOL was used to check if a

This commit replaces that with the janet_checktype function,
because that function is used for the same purpose in other places.

3. Make sure the value following '& is a symbol

Ian Shehadeh cb5af974a4 POC "rest" pattern in destructuring 
Add support for using [& rest] to match the remaining values
in an array or tuple when destructuring.

the rest pattern is implemented by pushing remaining values in the
rhs to the stack once & is found on the lhs.
Then tuple is called and the result is assigned
to the next symbol on the lhs.

This commit DOES NOT implement handling for malformed patterns.

Ian Shehadeh 60378ff941 windows: fix ev/read hang when called on fs stream 
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.

Calvin Rose d543f8857b Fix #892 - Remove racy ref counts for channels 
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.
