680f032001-09-14Henrik Grubbström (Grubba)  o Fixed tickets: 968, 1304, 1330, 1420, 1468, 1469, 1499, 1505, 1546, 1593, 1645, 1648, 1670, 1676, 1679, 1711, 1714, 1728, 1735, 1739, 1743, 1757, 1770, 1777, 1793, 1811, 1825, 1831, 1839, 1843, 1859, 1950, 1976, 2034, 2108, 2119, 2167, 2179, 2203, 2250
c242102001-07-27Johan Sundström  Changes since before then; Pike 7.0 ---------------------------------------------------------------------- o #pike Pike files can now be identified with which version of pike they where written for with the preprocessor directive #pike. The Pike interpreter can then use the apropriate compatibility features. Note that this can also be used for older versions of Pike; a Pike 7.0 or 0.6 script won't take offence just because you add a #pike line in the beginning of it but it will give 7.2 or later versions of pike a fair chance of running it witout complaining about incompatible changes to pike that were introduced later. By running the pike with a -V 7.0 (or 0.6 in the example given), you explicitly tell the compiler to assume compatibility mode of the given version, except where overridden by other #pike directives. o --features The pike binary can be started with the flag --features which will make it return a list of all "features" available. The subjective definition of a feature is something that depends on an external library, special features in the OS/hardware or extra compile options. o --info The --info flag shows, in addition to the feature list, some version and environment information about the pike binary. An example: Software......Pike Version.......Pike v7.2 release 30 WWW...........http://pike.idonex.se/ Main author...Fredrik Hübinette pike binary.../export/d1/nilsson/pike/7.2.30/bin/pike master.pike.../export/d1/nilsson/pike/7.2.30/lib/master.pike Module path.../export/d1/nilsson/pike/7.2.30/lib/modules Include path../export/d1/nilsson/pike/7.2.30/lib/include Program path.. Features......dynamic_modules threads out-of-band_data Crypto GL GTK Gdbm Gmp Gz Image.JPEG Image.GIF Image.TIFF Image.TTF Image.PNG Java Mird Mysql o All LFUNs may now be static. Callbacks used for overloading may now be declared as static. o Improved error diagnostics. The Pike compiler will now provide better error messages, i.e. more specific than "parse error" in many more cases than before. o Improved optimization of recursive functions. Tail recursion optimization is now applied in more cases. o Improved optimizer. The global optimizer now has a tree optimizer that performs parse tree transformations such as strength reduction optimization. o Improved support for 64bit platforms. The entire pike source has been audited and successfully compiled on 64 bit architectures. o Improved support for LFUNs in various efuns. Overloading is now taken into account in more places than before. o Improved type resolving. Pike can better derive the proper type of complex expressions. o Labeled break and continue. Loops can now be labeled and referenced to from break and continue. Example: int a, b; foo: for (int i = 1; i <= 4; i++) { a = i; switch (1) { case 1: if (i >= 3) break foo; if (i >= 2) continue foo; } b = i; } return ({a, b}); // Returns ({3, 1}) o Local variables at the same nesting depth may no longer overlap. This is a return to the behavior of Pike 0.6. (We promise not to change it again...) This may cause some compatibility problems with Pike 7.0 code. (See the #pike feature above) o More well-defined destruct order in the GC. Yep. Actually most of the GC has been rewritten from scratch. o New platforms supported. MacOS X (Darwin 1.2), Linux 2.4 IA64, MS Windows 2000, MS Windows XP, MS Windows XP 64bit. o Optimized compiler. The Pike compiler is now 50% faster than before. o Optimized the search algorithms some more. search() et al are now faster than before. o Several headerfiles renamed to improve portability. o Simulate is gone If you actually need Simulate, use #pike 7.0 and it will appear. o SQL sprintf style arguments It is now possible to make sprintf style SQL queries with automatic, database specific quoting. Example: db->query("SELECT * FROM things WHERE id > %d AND name LIKE %s", lowest, pattern); o Support for Unix system calls. Support for the Unix system calls setpgrp(), getsid() and setsid(), setrlimit(), getrlimit() (all in the system module, see below), support for setsid in Process.create_process(). o Support for cross-compilation. o Support for implicit create(). The following two class definitions are equivalent: class Foo { int a; string b; static void create(int _a, string _b) { a = _a; b = _b; } } class Foo(int a, string b) { } o Support for local constants. Constants can now be defined inside functions. o Support for the local::id syntax. Makes it possible to resolve symbols in the local scope. Example: class A { int foo() { return 1; } int bar() { return foo(); } int baz() { return local::foo(); } } class B { inherit A; int foo() { return 2; } } B()->bar() will return 2 while B()->baz() returns 1. o type_of() and _type_of() now return the type type. Example: constant boolean = typeof(0)|typeof(1); boolean flag = 1; int main( int argc, array(string) argv ) { flag = (argc>1)?(int)argv[1]:flag; write( "Type of flag is %O\n", typeof(flag) ); write( "Value of flag is %O\n", flag ); return 0; } o typedef syntex added. Example: typedef int(0..1) boolean; boolean flag = 1; int main( int argc, array(string) argv ) { flag = (argc>1)?(int)argv[1]:flag; write( "Type of flag is %O\n", typeof(flag) ); write( "Value of flag is %O\n", flag ); return 0; } o enum syntax added. Example: enum boolean { false, true } boolean flag = true; New modules ----------- o ADT.Stack Previously known as Stack. o Cache Plugin-based generic caching system, supporting chain-deletion of records. Currently supported storage areas are RAM, GDBM, Yabu or MySQL databases, removal policies are explicit remove, time-constrained, size-constrained, combined. o Calendar The new Calendar module. There is a big FAQ in its directory describing many of its capabilities. o Calendar_I The old Calendar module. Available as Calendar when #pike 7.0 is used. o Crypto.aes / Crypto.rijndael Rijndael is a block cipher, designed by Joan Daemen and Vincent Rijmen, which was the winning candidate algorithm for the AES (http://csrc.nist.gov/encryption/aes/). The cipher has a variable block length and key length. o Crypto.md2 The MD2 Message-Digest Algorithm, as defined in RFC 1319 (http://community.roxen.com/developers/idocs/rfc/rfc1319.html). o Geography Capable of converting between symbolic names for the countries to the actual country name. It can convert between differnet kinds of position systems such as longitude/latitude, UTM and Georef. The conversion can be done on any type of ellipsoid. 18 of the most common earth approximations are included. o Image.FreeType Support for FreeType 2.0. o Math.Angle For easy use of angles in computations. It can handle degrees, radians and gons and conversion between them. You can reference a degree angle with degrees, minutes and seconds. Includes methods for normalization, trigonometrical calculations etc. o Mird Glue module to libmird, a free simple database with transactions, see http://www.mirar.org/mird/ o PDF This is a glue module to pdflib,a "half-free" PDF generating library. o Parser.XML.DOM An implementation of DOM Level 1. See http://www.w3.org/DOM/. o Parser.XML.Tree An easy to use, lightweight module to traverse and manipulate XML trees. o Protocols.HTTP The API functions in Protocols.HTTP now take their URLs either as strings or Standards.URI objects. You also no longer need to set the authorization header on your own, if your URL contains user:password information, e.g. http://user:password@some.host.com/. o Protocols.IRC A client implementation of the IRC (Internet Relay Chat) protocol. o Protocols.SNMP Implements SNMP v1, according to RFC 1157: http://community.roxen.com/developers/idocs/rfc/rfc1157.html o Standards.ISO639_2 A module providing mapping from ISO-639-2 language codes to language names and vice versa. o Standards.URI Abstract class for URI:s (or URL:s) that both handles indexing out/altering the various individual components of a URI and correct resolving/reresolving of a URI with respect to another base URI, all according with RFC 2396: http://community.roxen.com/developers/idocs/rfc/rfc2396.html Protocols.HTTP now also accepts Standards.URI objects as input to all methods that previously used to accept only URL strings. o Stdio.Stat file_stat() now returns Stdio.Stat objects instead of arrays. These objects emulate the behaviour of the previously used arrays, but also provide an easier to use interface. (See the #pike feature above) o Tools.AutoDoc Extracts the new inline documentation format. We will post more information on this when this system has matured enough to build working pike reference manuals. Some information is available in files .autodoc_inlining and .autodoc_syntax in the top directory. o system A module housing various operating system calls made available to pike that previously used to be provided as efuns (hardlink, symlink, resolvepath, umask, chmod, chown, chroot stc.). Be prepared to see these efuns disappear to compat mode only in the future. They will, however, of course be available in the system module. o Added array Regexp match. Example: Regexp("[0-9]+")->match( ({ "hello", "12", "foo17" }) ); Returns ({ "12", "foo17" })
