d457aa5951 Deprecate file/popen. 
os/spawn is the prefered way of creating a subprocess and
communicating with it.

27b1f59aa9 Change Ctrl-C and move old behavior to Ctrl-Q 
This lets Janet be a better unix citizen and lets Ctrl-C
raise an interrupt. Trying to make Janet behave superficially
like a shell by overriding Ctrl-C is not helpful.

13d8d11011 Try new number hashing with frexp. 
This may be a bit slower in some cases but generally should
have much better hashing for numbers.

Merge pull request #540 from felixr/better-quicksort 
Improve quicksort to avoid worst case performance on sorted input
 2020-12-26 15:23:01 -06:00
Felix Riedel
3e742ffc4c Improve quicksort to avoid worst case performance. 
The current implementation will have quadratic behaviour for already
sorted arrays because it picks the last element as pivot. In an sorted
array this splits the array repeatedly into the biggest value and all
other values.

The implementation in this commit uses the *median of three* as pivot.

`janet -e "(sort (range 10000))"` to reproduce quadratic behaviour.

2ec12fe06f Improve hashing of numbers 
Using an integer hash (https://stackoverflow.com/a/12996028/60617) on
the number casted to int32 combined with lower bits of the number.

c76e0ae685 Use boost's way of combining hash values for arrays and kv pairs. 
`seed ^= hash_value(v) + 0x9e3779b9 + (seed << 6) + (seed >> 2);`
from https://www.boost.org/doc/libs/1_35_0/doc/html/boost/hash_combine_id241013.html

The current way of combining hashes peforms poorly on hash values of
numbers. Changing the way hashes are combined canlead to a significant speed up:

```
time janet_new -e '(def tbl @{}) (loop [x :in (range 1000) y :in (range 1000)] (put tbl {0 x 1 y} true))'
3.77s user 0.08s system 99% cpu 3.843 total

time janet_orig -e '(def tbl @{}) (loop [x :in (range 1000) y :in (range 1000)] (put tbl {0 x 1 y} true))'
48.98s user 0.15s system 99% cpu 49.136 total

a55354357c Make dofile error if source file errors. 
This should make dofile a bit easier to use.
It also means that import properly raises errors when
things go bad.

945cbcfad6 Tail recursive match implementation. 
This implementation uses multiple passes on patterns
to remove the need for a sentinel value to check if there was a match.
This also re-uses extracted subpatterns for complicated patterns.

9d23192614 Add ev/deadline and ev/with-deadline. 
This should be more useful than timeouts in real-world
use cases. The deadline system is based on fibers and is target
to much more coarse-grained (and therfor reliable) timeouts than things
like ev/sleep and timeout arguments.
