bf01bf631d More work on windows networking code. 
Remove use of WSARecv and WSASend since for whatever reason
they seem suspect. We may want to revisit this later.
 2021-01-11 18:00:31 -06:00
Calvin Rose
80c5ba32b5 Remove wait from CI testing for networking tests. 
We want to expose any existing race conditions.

bcba0c0279 Fix #548 - string/split bug.

behavior that was documented only applies to to string/replace-all.

0f16f21677 Make builds deterministic again. 
Also prevent marshal from creating multiple copies of
a function - (marshal function pointer before function def pointer).

cbdea8f331 Make os/execute cooperate with ev module. 
os/execute, os/proc-wait do not block (currently posix only).
This uses the self-pipe trick to turn signals into a pollable entity.
 2020-11-29 15:36:21 -06:00
Calvin Rose
7aa4241662 Add testing for the new reindent behavior. 
This also provides a reference function to reimplement
the behavior in Janet.
 2020-11-28 12:18:36 -06:00
Calvin Rose
776ce586bc Add line and column combinators to peg. 
These capture the line and column number of the current position
in the matched text. This is useful for error reporting as well
as indentation checking.

This works by lazily creating an index on first use that stores all
newline character indices in order. We can then do a binary search on
this to get both line number and column number in log(n) time.
This is good enough for most use cases and doesn't slow down the common case at all
- these will not be commonly used patterns in a hot loop so it is not worth to try and
optimize this at all. Constant time look up should be possible but at
the cost of complicating code and slowing down all matching to check for
new lines.

a3e812b86d Fix #505 - bat int64 parsing. 
Fixes an off-by-1 error.

Also makes windows testing hopefully a bit less flaky.

a3f98091c4 Fix #509

continuing.

cdcb774dc8 Add os/pipe and os/open. 
ev/pipe -> os/pipe, and os/open is a wrapper
around the open system call.

dc51bd09f7 Make sure all test logs go to the same stream. 2020-11-14 15:56:48 -06:00
Calvin Rose
12f09ad2d7 Add ev/pipe and move stream code into ev.c 
Also adds a lot to the C API and changes things up.
 2020-11-14 14:29:11 -06:00
Calvin Rose
d6391f2d70 Get windows IOCP working for accept. 
This also changes the api of servers slightly -
in light of having support for ev tasks, it is probably better
to remove the "simple" server code and replace it with some Janet
or remove it all together. While convenient, it has issues with error
handling and rigidity.

7e7498350f Fix #463 
Fix outdated code in macex1, such as checking for unquote-splicing,
    which no longer exists. Also fix macex1 for quasiquoted tables and
    structs. macex1 is not the macro expander used by the compiler, so
    these bugs only affected code which called macex manually, such as
    the short-fn macro.

ba08e487cb Disable PRF by default. 
Since it is not any better by default without initializing the key, we
disable it by default. It can be turned on with JANET_PRF in
janetconf.h.

6d096551f0 Add Peg combinators 'to' and 'thru'. 
Inpsired by the REBOL operators of the same name, these
combinators match bytes up to or inculding a given pattern.
(to patt) is (almost) equalivalent to (any (if-not patt 1)), and
(thru patt) is equivalent to (* (to patt) patt). The one difference
is that if the end of the input is reached and patt is not
matched, the entire pattern does not match.

a87015598c 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.

72beeeeaaa Move funcenv verification to runtime. 
Lazy verification makes it easier to not leave funcenvs
in an invalid state, as well as be more precise with the validation.
We needed to verify the FuncEnvs actually pointed to a stack frame if
they were of the "on-stack" variant. There was some minor checking
before, but it was not enough to prevent func envs from pointing to
memory that was off of the fiber stack, overlapping stack frames, etc.

3d40c95e80 Add ability to Janet signal from C functions. 
While C functions are not re-entrant, signaling from a C function
can be used to implement async returns. When resuming a fiber that
signalled from within a C function, the fiber is started after the
instruction that emitted the signal. The resume argument is used
as the return result from the c function.

022be217a2 Remove ==, not==, and order[<,<=,>,>=]. 
This unifies equality and comparison checking. Before, we had
separate functions and vm opcodes for comparing general values vs.
for comparing numbers, where the numberic functions were polymorphic and
had special cases for handling NaNs. By unfiying them, abstract types
can now better integrate with other number types and behave as keys.

For now, the old functions are aliased but will eventually be removed.

f1afc5b0b4 Address #214 
This adds several common patterns, which are defined in
boot.janet. This essentially gives more primitive patterns
to work with out of the box.

Fix build when JANET_REDUCED_OS is defined.

49954c7a30 Remove top-level unquote for comptime macro 
True top level unquote currently requires basically double compilation
as it currently stands. Also, implementing such double compilation
looses all source mapping information. This is a compromise
implementation that makes it clear that this works differently than
a true top-level unquote.

5ae520a2c9 Integers convert to plain number strings. 
A user can use (type n) to find the true type, the old behavior did not
seem useful for most uses of the string function.

aee1687215 Add RNG functionality to the math/ module. 
The new RNG wraps up state for random number generation, so
one can have many rngs and even marshal and unmarshal them.
Adds math/rng, math/rng-uniform, and math/rng-int.

Also introduce `in` and change semantics for
indexing out of range. This commit enforces stricter
invariants on keys when indexing via a function call
on the data structure, or the new `in` function.

The `get` function is now more lax about keys, and will
not throw an error when a bad key is used for a data structure, instead
returning the default value.

6ceaf9d28d Add with-vars 
This helps for temporarily setting vars in a safe
manner that is guaranteed not to leave vars in a bad state
(assuming that a fiber does not emit debug or use signal and
 is never resumed).

d47804d222 Add prin, eprint, and eprin functions. 
The print family of functions now writes output
to an optional buffer instead of a file bound to :out.
This means output can be more easily captured an redirected.
