7df7b02014-10-03Per Hedbor Pike 8.1: Changes since Pike 8.0 (scratch area for future release notes)
2ac4992011-03-09Martin Stjernholm ----------------------------------------------------------------------
dca6762014-11-03Martin 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.
a72ec62016-01-04Per 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.
7a82ac2016-01-26Martin Nilsson o Random rewrite The random functions have been rewritten to ensure security by default. random_string() and random() now gets its data directly from the operating system random generator, e.g. /dev/urandom on unix. 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. For consumers of random data that have additional requirements, different random generators are exposed in the new module Random. The module have the following generators. - 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 This generator cretes the same sequence of random numbers for a given seed, with good pseudo random properties. - Random.Hardware This generator accesses he hardware random generator, when available. - Random.Fast This generator takes entropy from the Random.System, but feeds that into a cryptographic pseudo random number generator to be able to output data fast. This is not the default random number generator to avoid loading crypto code all the times. Comparing the different generators with eachother gives the following approximate speeds on a Linux system with hardware random support. Random.System 1.0 Pike 8.0 random_string 0.45 Random.Hardware 0.25 Random.Fast 0.20 Random.Deterministic 0.20
9654e02015-10-15Martin Nilsson Incompatible changes -------------------- o Gz.crc32 now only returns positive results.
dca6762014-11-03Martin Nilsson Removed features and modules ---------------------------- o Compatibility for Pike versions before 7.8 is no longer available.
a72ec62016-01-04Per Hedbor o GTK1 library is deprecated, so glue code is removed.
951b442016-01-04Martin Nilsson New modules ----------- o ADT.Scheduler o ADT.TreeScheduler o Filesystem.Zip o Stdio.FakePipe o Parser.Markdown
f5f00d2016-01-26Martin Nilsson 
951b442016-01-04Martin Nilsson o Crypto.Checksum
f5f00d2016-01-26Martin Nilsson  This module collect non-cryptographic checksums. Support for crc32, adler32 and Castagnoli CRC (CRC32C).
951b442016-01-04Martin Nilsson o Protocols.HTTP2 o Bittorrent.DHT
4fd7212016-01-04Martin Nilsson o MsgPack
951b442016-01-04Martin Nilsson 
a72ec62016-01-04Per Hedbor New features ------------
be725d2016-01-04Martin Nilsson o Gmp.mpf is now implemented using gmpf if the library is available.
992e242015-08-24Martin Nilsson 
83a8f52015-11-09Martin 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.
dca6762014-11-03Martin Nilsson Building and installing ----------------------- o GMP 4.1 or later is now required.
9721ab2016-01-11Martin Nilsson  o C99 assumed The configure tests will not check for functions defined in C99 anymore and C99 compiler support is assumed.
