|
dca676 | 2014-11-03 | Martin Nilsson | | New language features
---------------------
o Unlimited character constant size.
There is no longer any limit to the size of character constants,
e.g. 'acdefghijk' creates the bignum 0x61636465666768696a6b.
|
a72ec6 | 2016-01-04 | Per Hedbor | | o 'auto' type added.
This is much like a strict typed mixed. The actual type is deduced
compile-time.
The main use case is as variables in foreach when looping over
complexly typed values, or as types in macro-defined functions and
such.
auto can be used as return type for a function, it will be the
logical or of all the types of the return statements in the
function.
o typeof(X) can now be used as a type.
The main use case is in macros, but it might be useful for other
things as well (as an example in a typedef).
typedef typeof(Val.true)|typeof(Val.false) bool;
typeof, when used like this, behaves very much like the C++
decltype() expression.

7a82ac | 2016-01-26 | Martin Nilsson | | o Random rewrite
The random functions have been rewritten to ensure security by
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | default. random_string() and random() now get their data directly
from the operating system random generator, i.e. /dev/urandom on
most unixen. This is about half the speed compared with the
random_string function in Pike 8.0, but is now as secure as the
system random generator.
|
7a82ac | 2016-01-26 | Martin Nilsson | |
For consumers of random data that have additional requirements,
different random generators are exposed in the new module
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | Random. The module has the following generators:
|
7a82ac | 2016-01-26 | Martin Nilsson | |
- Random.Interface
This is not actually a generator, but an interface class that is
inherited into all the other generators. It contains code that can
turn the output from the random_string method into random numbers
with different limits without introducing bias. It also contains
code for all the different variants of random() on different
types. This is currently not possible to implement in Pike code,
as the typing is too complicated and it is not possible to access
private/protected _random methods in objects.
- Random.System
This generator maps directly on top of the system random
generator. This is the default generator used for random() and
random_string().
- Random.Deterministic
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | This generator creates the same sequence of random numbers for a
|
7a82ac | 2016-01-26 | Martin Nilsson | | given seed, with good pseudo random properties.
- Random.Hardware
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | This generator accesses the hardware random generator, when
|
7a82ac | 2016-01-26 | Martin Nilsson | | available.
- Random.Fast
This generator takes entropy from the Random.System, but feeds
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | it into a cryptographic pseudo random number generator to be
|
7a82ac | 2016-01-26 | Martin Nilsson | | able to output data fast. This is not the default random number
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | generator to avoid loading crypto code all the time.
|
7a82ac | 2016-01-26 | Martin Nilsson | |
|
f8800b | 2016-01-26 | Henrik Grubbström (Grubba) | | Comparing the different generators with each other gives the
following approximate speeds on a Linux system with hardware
random support:
|
7a82ac | 2016-01-26 | Martin Nilsson | |
Random.System 1.0
Pike 8.0 random_string 0.45
Random.Hardware 0.25
Random.Fast 0.20
Random.Deterministic 0.20

o Gz.crc32 now only returns positive results.
|
dca676 | 2014-11-03 | Martin Nilsson | | Removed features and modules
----------------------------
o Compatibility for Pike versions before 7.8 is no longer available.
|
a72ec6 | 2016-01-04 | Per Hedbor | | o GTK1 library is deprecated, so glue code is removed.
|
951b44 | 2016-01-04 | Martin Nilsson | | New modules
-----------
o ADT.Scheduler
o ADT.TreeScheduler
o Filesystem.Zip
o Stdio.FakePipe
o Parser.Markdown

|
f5f00d | 2016-01-26 | Martin Nilsson | |
This module collect non-cryptographic checksums. Support for crc32,
adler32 and Castagnoli CRC (CRC32C).
|
951b44 | 2016-01-04 | Martin Nilsson | | o Protocols.HTTP2
o Bittorrent.DHT
|
4fd721 | 2016-01-04 | Martin Nilsson | | o MsgPack
|
951b44 | 2016-01-04 | Martin Nilsson | |
|
a72ec6 | 2016-01-04 | Per Hedbor | | New features
------------
|
be725d | 2016-01-04 | Martin Nilsson | | o Gmp.mpf is now implemented using gmpf if the library is available.
|
992e24 | 2015-08-24 | Martin Nilsson | |
|
83a8f5 | 2015-11-09 | Martin Nilsson | | C-level API changes
-------------------
o The contract for functions is now changed so that a function is no
longer required to clean the stack. The topmost value of the stack
will be regarded as the return value and the rest of the items on
the stack, compared to before the function arguments were pushed,
will be popped and discarded. Efuns still have to clean their stack
as previously.
|
dca676 | 2014-11-03 | Martin Nilsson | | Building and installing
-----------------------
o GMP 4.1 or later is now required.
|
9721ab | 2016-01-11 | Martin Nilsson | |
o C99 assumed
The configure tests will not check for functions defined in C99
anymore and C99 compiler support is assumed.
