2f5dd42008-06-29Martin Nilsson This is a high level list of changes between Pike 7.6 and Pike 7.8. General bug fixes, build fixes and optimizations are not mentioned here. For a complete list of changes, please consult the CVS changelog either directly or through Code Librarian.
92c1842008-05-07Henrik Grubbström (Grubba) 
2f5dd42008-06-29Martin Nilsson  New / improved language functionality -------------------------------------
71ef5a2007-11-02Henrik Grubbström (Grubba) 
4d48e42004-10-30Martin Stjernholm o New syntax to index from the end in range operations.
92c1842008-05-07Henrik Grubbström (Grubba) 
4d48e42004-10-30Martin Stjernholm  A "<" can be added before an index in the [..] operator to count
e13e682008-09-21Martin Stjernholm  from the end instead, beginning with 0 for the last element. This is convenient to e.g. chop off the last element in an array: a[..<1].
4d48e42004-10-30Martin Stjernholm  o New `[..] operator function.
92c1842008-05-07Henrik Grubbström (Grubba) 
4d48e42004-10-30Martin Stjernholm  Range operations have been separated from the `[] operator function
bc2a632008-05-10Henrik Grubbström (Grubba)  and are now handled by the new `[..] which provides greater control
66f21a2008-05-10Henrik Grubbström (Grubba)  for how the range bounds are specified. For compatibility, if there is no `[..] then `[] is still called for range operations.
4d48e42004-10-30Martin Stjernholm 
d1c4332008-08-28Martin Nilsson  The `[..] callback will get four arguments, start value, start type, end value and end type. The type arguments is any of Pike.INDEX_FROM_BEG, Pike.INDEX_FROM_END or Pike.OPEN_BOUND. Here are a few examples of what input arguments different calls would generate. [..] 0 OPEN_BOUND 0 OPEN_BOUND [1..] 1 INDEX_FROM_BEG 0 OPEN_BOUND [..2] 0 OPEN_BOUND 2 INDEX_FROM_BEG [3..4] 3 INDEX_FROM_BEG 4 INDEX_FROM_BEG [<5..] 5 INDEX_FROM_END 0 OPEN_BOUND [6..<7] 6 INDEX_FROM_BEG 7 INDEX_FROM_END
e399bc2007-11-11Martin Nilsson 
85b3d32004-12-19Henrik Grubbström (Grubba) o Generalized this and this_program.
92c1842008-05-07Henrik Grubbström (Grubba) 
85b3d32004-12-19Henrik Grubbström (Grubba)  It is now possible to refer to inherits in objects. Example:
92c1842008-05-07Henrik Grubbström (Grubba) 
85b3d32004-12-19Henrik Grubbström (Grubba)  class A { int a; void foo() { werror("A\n"); } } class B { inherit A; int b; void foo() { werror("B\n"); } A::this_program get_a() { return A::this; } }
92c1842008-05-07Henrik Grubbström (Grubba) 
85b3d32004-12-19Henrik Grubbström (Grubba)  In the above B()->get_a() will return an object with two symbols, 'a' and 'foo', but B()->get_a()->foo() will still write "B\n".
71ef5a2007-11-02Henrik Grubbström (Grubba) o Added support for getters and setters.
92c1842008-05-07Henrik Grubbström (Grubba) 
71ef5a2007-11-02Henrik Grubbström (Grubba)  It is now possible to simulate variables with functions. Example:
92c1842008-05-07Henrik Grubbström (Grubba) 
71ef5a2007-11-02Henrik Grubbström (Grubba)  class A { private int a;
98c7e42007-11-15Martin Nilsson  int `b() { return a; } // Getter for the symbol b. void `b=(int c) { a = c; } // Setter for the symbol b.
71ef5a2007-11-02Henrik Grubbström (Grubba)  int c() {
98c7e42007-11-15Martin Nilsson  return b; // Calls `b().
71ef5a2007-11-02Henrik Grubbström (Grubba)  } } object a = A();
98c7e42007-11-15Martin Nilsson  a->b = 17; // Calls `b=(17). werror("%d\n", a->b); // Calls `b().
71ef5a2007-11-02Henrik Grubbström (Grubba) 
9056902008-05-10Henrik Grubbström (Grubba) o Casting to derived types. It is now possible to call a value of type type to perform the corresponding value cast. eg: typedef string MyString; return MyString(17); // Casts 17 to "17".
73fe402004-11-14Martin Stjernholm o Unicode escapes.
92c1842008-05-07Henrik Grubbström (Grubba) 
73fe402004-11-14Martin Stjernholm  Pike now understands the common way to escape unicode chars, using \uxxxx and \Uxxxxxxxx escapes. These escapes works both in string and character literals and in the preprocessor. The latter means that unicode escapes can be used in identifiers, which is useful if they contain characters that can't be represented raw in the source code charset.
482f8b2008-06-30Martin Nilsson o Stricter type checker for function calls.
92c1842008-05-07Henrik Grubbström (Grubba) 
2f5dd42008-06-29Martin Nilsson  The type checker for function calls is now based on the concept of currification. This should provide for error messages that are more easily understood. It also is much better att typechecking function calls utilizing the splice (@) operator. The mechanisms used by the typechecker are also made available as Pike.get_first_arg_type(), Pike.low_check_call() and Pike.get_return_type().
71ef5a2007-11-02Henrik Grubbström (Grubba)  o Stricter typing of strings.
92c1842008-05-07Henrik Grubbström (Grubba) 
482f8b2008-06-30Martin Nilsson  The string type may now have an optional value range.
92c1842008-05-07Henrik Grubbström (Grubba) 
71ef5a2007-11-02Henrik Grubbström (Grubba)  string(0..255) bytes;
43ec872008-06-29Henrik Grubbström (Grubba) o Support for having multiple different active backend implementations.
6de0ec2004-05-11Henrik Grubbström (Grubba) 
b5396c2008-09-21Henrik Grubbström (Grubba)  In Pike 7.6 and earlier, there could only be one active backend implementation at a time, which was the one selected for best performance with lots of files (cf Pike.Backend below). This led to problems when pike attempted to run poll device based backends on older versions of operating systems where poll devices aren't available, and with extra overhead when the backend was only used with a very small set of files. Basic backend implementations: - Pike.PollDeviceBackend This is a backend that is implemented based on keeping the state in the operating system kernel and thus eliminating the need to send the state in every system call. This is however not available on all operating systems. Currently supported are /dev/poll (Solaris, etc), epoll(2) (Linux) and kqueue(2) (FreeBSD, MacOS X). - Pike.PollBackend This is a backend that is implemented based on the poll(2) system call. This is typically available on all System V or Linux based systems. - Pike.SelectBackend This is a backend that is implmented based on the BSD select(2) system call. This is supported on all operating systems. Derived backend implementations: - Pike.Backend This is the backend selected among the basic backend implementations, which is likely to have the best performance when there are lots of files in the backend. - Pike.SmallBackend This is the backend selected among the basic backend implementations, which is likely to have the best performance when there are very few files in the backend. Note that there is also a default backend object: - Pike.DefaultBackend This is the Pike.Backend object that is used if no other backend object has been specified.
9228fd2008-09-19Martin Stjernholm 
71ef5a2007-11-02Henrik Grubbström (Grubba) o cpp
92c1842008-05-07Henrik Grubbström (Grubba) 
71ef5a2007-11-02Henrik Grubbström (Grubba)  The preprocessor now supports macro expansion in the #include and #string directives.
482f8b2008-06-30Martin Nilsson  #include USER_SETTINGS
9e891d2005-02-09Martin Stjernholm o Destruct reason passed to lfun::destroy.
92c1842008-05-07Henrik Grubbström (Grubba) 
9e891d2005-02-09Martin Stjernholm  lfun::destroy now receives an integer flag that tells why the object is being destructed, e.g. if it was an explicit call to destroy(), running out of references, or reaped by the garbage collector.
afa4822006-12-29Martin Nilsson  These integers are defined in the new Object module as
b5396c2008-09-21Henrik Grubbström (Grubba)  DESTRUCT_EXPLICIT, DESTRUCT_NO_REFS, DESTRUCT_GC and
afa4822006-12-29Martin Nilsson  DESTRUCT_CLEANUP.
71ef5a2007-11-02Henrik Grubbström (Grubba) o Improved support for mixin.
92c1842008-05-07Henrik Grubbström (Grubba) 
71ef5a2007-11-02Henrik Grubbström (Grubba)  The Pike compiler now supports mixin for symbols that have been declared static.
661bb72008-07-14Peter Bortas  FIXME: Explain in one or two sentences what a mixin is and what it's good for.
71ef5a2007-11-02Henrik Grubbström (Grubba) 
f2be742008-09-21Peter Bortas  FIXME: Should that be protected instead of static? FIXME: Is this really a change, and why are we talking about mixins instead of multiple inheritance variables?
71ef5a2007-11-02Henrik Grubbström (Grubba) o Implicit and explicit create().
92c1842008-05-07Henrik Grubbström (Grubba) 
71ef5a2007-11-02Henrik Grubbström (Grubba)  The compiler now supports defining classes with both an implicit and an explicit create(). o Warnings for unused private symbols.
92c1842008-05-07Henrik Grubbström (Grubba) 
71ef5a2007-11-02Henrik Grubbström (Grubba)  The compiler now checks that all symbols that have been declared private actually are used.
482f8b2008-06-30Martin Nilsson  class A (int i) { protected string j; protected void create(string j) { A::j = reverse(j); } }
43ec872008-06-29Henrik Grubbström (Grubba) o Warnings for unused local variables. The compiler now checks that all local variables are used.
afa4822006-12-29Martin Nilsson o Unicode
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  Case information and the Unicode module are updated to Unicode
70a6932008-05-29Martin Nilsson  5.1.0.
afa4822006-12-29Martin Nilsson 
2f5dd42008-06-29Martin Nilsson o The keyword protected
92c1842008-05-07Henrik Grubbström (Grubba) 
e399bc2007-11-11Martin Nilsson  The modifier protected is now an alias for the modifier static.
d1c4332008-08-28Martin Nilsson  NOTE: In the next release static will be deprecated.
e399bc2007-11-11Martin Nilsson 
2427442008-06-29Per Hedbor o extern declared variables Variables can now be declared as 'extern'. This means that inheriting classes must have them. They can be used like normal variables in the base class. Example: class A { extern int a; int dummy() { return ++a; } }
33f0672008-04-26Henrik Grubbström (Grubba) o __attribute__ and __deprecated__
92c1842008-05-07Henrik Grubbström (Grubba) 
78dfe32008-09-15Henrik Grubbström (Grubba)  It's now possible to set custom attributes on types, so that it is possible to make custom type checking. This is currently used to improve the argument checking for sprintf() and related functions, and for marking symbols as deprecated.
2a73e02008-05-30Henrik Grubbström (Grubba)  eg: __deprecated__ mixed obsolete_function(); __deprecated__(mixed) obsolete_return_value(); mixed fun(__deprecated__(mixed) obsolete_arg); __deprecated__(mixed) obsolete_variable;
33f0672008-04-26Henrik Grubbström (Grubba) 
d53f302008-08-29Martin Nilsson  The deprecated type flag using __deprecated__ is a convenience syntax to use instead of e.g.
d1c4332008-08-28Martin Nilsson 
d53f302008-08-29Martin Nilsson  void f(void|__attribute__("deprecated",int) timeout) Other uses of __attribute__ in type declarations can be seen in e.g. the type for werror(): > typeof(werror); (1) Result: scope(0,function(string : int) | function(__attribute__("sprintf_format", string), __attribute__("sprintf_args", mixed) ... : int) | function(array(string), mixed ... : int))
0d73d72008-06-29Martin Nilsson 
92c1842008-05-07Henrik Grubbström (Grubba) o __func__ The symbol __func__ now evaluates to the name of the current function. Note that this name currently can differ from the
e13e682008-09-21Martin Stjernholm  declared name in case of local functions (i.e. lambdas). Note
b5396c2008-09-21Henrik Grubbström (Grubba)  also that __func__ behaves like a literal string, so implicit
92c1842008-05-07Henrik Grubbström (Grubba)  string concatenation is supported. eg: error("Error in " __func__ ".\n");
d1c4332008-08-28Martin Nilsson o __DIR__
661bb72008-07-14Peter Bortas 
d1c4332008-08-28Martin Nilsson  __DIR__ is a new preprocessor symbol that resolves to the directory that the current file is placed in. Similar to how __FILE__ points out the file the code is placed in.
661bb72008-07-14Peter Bortas 
2a73e02008-05-30Henrik Grubbström (Grubba) o #pragma {no_,}deprecation_warnings Warnings for use of deprecated symbols can be turned off for a segment of code with #pragma no_deprecation_warnings and turned on again with #pragma deprecation_warnings
d1c4332008-08-28Martin Nilsson o Compatibility name spaces Older versions of a function can be reached through its version name space. For example the 7.4 version of the hash function can be called through 7.4::hash(). o Iterator API
482f8b2008-06-30Martin Nilsson 
d1c4332008-08-28Martin Nilsson  The iterator API method Iterator->next() is no longer optional.
482f8b2008-06-30Martin Nilsson 
2f5dd42008-06-29Martin Nilsson  Extensions and New Functions ----------------------------
482f8b2008-06-30Martin Nilsson o exit() Exit now takes optional arguments to act as a werror in addition to exiting the process. exit(1, "Error while opening file %s: %s\n", path, strerror(errno())); o getenv()/putenv() getenv() and putenv() are now accessing and modifying the real
56398b2008-06-29Per Hedbor  environment.
b28e2e2008-09-21Martin Nilsson o get_dir() Calling get_dir() with no arguments will now return the directory listing for the current directory.
482f8b2008-06-30Martin Nilsson o undefinedp()/destructedp() undefinedp() and destructedp() have been added as more readable
56398b2008-06-29Per Hedbor  alternatives to zero_type().
431ebd2008-05-09Martin Nilsson o limit() The new toplevel function limit(a, x, b) is a convenience function that works like min(max(a,x),b).
b28e2e2008-09-21Martin Nilsson o listxattr(), getxattr(), setxattr(), removexattr() The new xattr functions listxattr(), getxattr(), setxattr and removexattr() allows extended file attributes to be modified from within Pike.
187e1f2008-05-18Henrik Grubbström (Grubba) o sprintf() and sscanf()
2427442008-06-29Per Hedbor  - sprintf() now attempts to lookup the name of the program when formatting types of objects and programs. - The new formatting directive %H can be used to format a string as
661bb72008-07-14Peter Bortas  a binary hollerith string.
2427442008-06-29Per Hedbor  > sprintf("%2H", "Hello"); (1) Result: "\0\5Hello" - The new formatting directive %q can be used to format a atring as a quoted string, quoting all control character and non-8-bit characters as well as quote characters. Like %O but always on one line. > sprintf("%q", "abc \x00 \" \' \12345"); (1) Result: "\"abc \\0 \\\" ' \\u14e5\""
d53f302008-08-29Martin Nilsson  - Ranges in sscanf sets can now start with ^, even at the beginning of the set specifier. Example: %[^-^] matches a set with only ^ in it. To negate a set with - in it, the - character must now be the last character in the set specifier.
2427442008-06-29Per Hedbor o encode/decode value and programs --with-portable-bytecode is now the default. Pike programs that have been dumped on one architecture now can be decoded on another.
187e1f2008-05-18Henrik Grubbström (Grubba) 
482f8b2008-06-30Martin Nilsson o gethrtime, gethrvtime, gauge Added support for POSIX style timers using clock_gettime(3). Notably this fixes nice high resolution thread local cpu time and monotonic real time on reasonably modern Linux systems. There are new constants CPU_TIME_* and REAL_TIME_* in the System module to allow pike code to query various properties of the CPU and real time clocks in use.
326a9d2007-02-23Martin Nilsson o ADT.BitBuffer
e399bc2007-11-11Martin Nilsson  Added read() method that reads whole bytes from the buffer and returns as a string.
326a9d2007-02-23Martin Nilsson  o ADT.Queue
e399bc2007-11-11Martin Nilsson 
482f8b2008-06-30Martin Nilsson  It is now possible to use sizeof() and values() on a Queue object to get the size of the queue and all elements in the queue as an array.
e399bc2007-11-11Martin Nilsson  o ADT.Stack
482f8b2008-06-30Martin Nilsson  Stack objects can now be cast to arrays to get all elements on the stack.
326a9d2007-02-23Martin Nilsson  o ADT.Struct
e399bc2007-11-11Martin Nilsson  - New Item class SByte, SWord and SLong represents a signed byte, word and longword respectively. - The Item classes int8, uint8, int16, uint16, int32, uint32, int64
612ad42008-06-29Martin Nilsson  and uint64 are aliases for already existing Item classes.
e399bc2007-11-11Martin Nilsson  - sizeof() now works for empty Struct objects. - sizeof() can be used on individual Item objects. - Struct objects can now be used as Items in other Structs.
612ad42008-06-29Martin Nilsson  class Pair { inherit ADT.Struct; Item id = uint8(); Item val = uint64(); } class File { inherit ADT.Struct; Item magic = Chars(4); Item one = Pair(); Item two = Pair(); }
326a9d2007-02-23Martin Nilsson  o Array
e399bc2007-11-11Martin Nilsson  - New function combinations() returns all combinations of a specified length with elements from a given array. - Added push(), pop(), shift() and unshift() functions for Perl weirdos.
326a9d2007-02-23Martin Nilsson  o Calendar
e399bc2007-11-11Martin Nilsson  - Added new calendar Badi, used in the Baha'i religion. - Fixed bugs in discordian, where the year() was off by 1166 and now() was off 5 month per year. - Time objects now handle * and / with floats. A split() method has
b217b32008-09-21Martin Nilsson  been added for more advanced splitting where the preferred time quanta can be given as an argument.
e399bc2007-11-11Martin Nilsson  - A new formatting method format_ext_time_short() has been added to Time objects. - Timezones are now read from /etc/localtime, if available.
326a9d2007-02-23Martin Nilsson 
80e2fe2008-09-08Martin Stjernholm  - Cleaned up year-day (yd) handling so that it never goes below 1. Instead be careful to use either year (y) or week-year (wy) depending on context. - Fixed inconsistent range handling in year() and years() that made them almost but not quite zero-based. Now they are one-based just like day()/days(), month()/months() etc. - Cleaned up conversion between weeks and years: E.g. if a week has days in two years then converting it to years will produce a range of both years. The attempt to always map a week to a single year is gone since it's inconsistent with how other overlapping time ranges are handled. If the user wants to convert a week to the year it "unambiguously" belongs to, (s)he can do Calendar.ISO.Year(week->year_no()). - Did away with the attempt to map leap days between February 24th and 29th before and after year 2000, since doing so break date arithmetic. - The last four changes above are not entirely compatible. Compatibility with 7.6 and older is retained with #pike 7.6.
92c1842008-05-07Henrik Grubbström (Grubba) o CompilerEnvironment & CompilerEnvironment()->PikeCompiler
d1c4332008-08-28Martin Nilsson  The Pike compiler has been refactored to be more object-oriented and more transparent. It is now possible to customize the compiler by overloading functions in the above two classes. The compiler object used by Pike internally is available through DefaultCompilerEnvironment.
92c1842008-05-07Henrik Grubbström (Grubba) 
326a9d2007-02-23Martin Nilsson o Debug
e399bc2007-11-11Martin Nilsson  The new function count_objects() will return the different kinds of objects existing within the Pike process. Useful when trying to pinpoint a leak of Pike objects. o Error The new function mkerror() will normalize any thrown value into a proper error object (or 0).
326a9d2007-02-23Martin Nilsson  o Filesystem
e399bc2007-11-11Martin Nilsson  Traversion has been extended with two new create arguments. The first one is a flag to supress errors and the other is a sorting function which will be applied to the entries in every directory. This callback can also be used to filter the directory entries.
326a9d2007-02-23Martin Nilsson  o Float
e399bc2007-11-11Martin Nilsson  The function isnan() can be used to check if a float is Not a Number.
92c1842008-05-07Henrik Grubbström (Grubba)  > Float.isnan(Math.inf/Math.inf); (1) Result: 1
326a9d2007-02-23Martin Nilsson 
35c4b12008-05-09Martin Nilsson o Gdbm Gdbm databases can be opened in synchronous mode or locking mode by adding "s" or "l" respectively in the mode parameter to the create method.
326a9d2007-02-23Martin Nilsson o Geography.Position
e399bc2007-11-11Martin Nilsson  It is now possible to encode Position objects with encode_value().
326a9d2007-02-23Martin Nilsson  o GLUE
e399bc2007-11-11Martin Nilsson  - The default event callback will now exit both on Exit and Escape events. - The texture, list and light id generators will now be created after we are sure that GL has been initialized, to prevent crashes on several systems. - BaseTexture and BaseDWIM now supports clamped textures.
b28e2e2008-09-21Martin Nilsson o Gmp
4c12f22008-09-21Martin Nilsson  Many small changes to fix Gmp build issues on different platforms.
b28e2e2008-09-21Martin Nilsson  The most visible being that the Gmp module now is statically linked to work around Mac OS X 10.5 linker issues.
35c4b12008-05-09Martin Nilsson o Gz - Added compress() and uncompress() functions as an simpler and more efficient but non-streaming interface. - Support for RLE And FIXED compression method, if supported by
b28e2e2008-09-21Martin Nilsson  zlib. Give Gz.RLE or Gz.FIXED to the strategy argument of compress() or the deflate constructor.
35c4b12008-05-09Martin Nilsson 
b28e2e2008-09-21Martin Nilsson  - Added support for configurable compression window size. This is the last argument to compress() and the constructor for inflate/deflate.
35c4b12008-05-09Martin Nilsson  o Image.Colortable
612ad42008-06-29Martin Nilsson  - The new method greyp() can be used to query if the color in the color object is grey.
35c4b12008-05-09Martin Nilsson 
612ad42008-06-29Martin Nilsson  - Partial support for serializing color objects. Dithering type and lookup mode is not currently saved.
35c4b12008-05-09Martin Nilsson 
326a9d2007-02-23Martin Nilsson o Image.Dims
e399bc2007-11-11Martin Nilsson  Support for parsing out the dimensions of TIFF files has been added.
326a9d2007-02-23Martin Nilsson 
35c4b12008-05-09Martin Nilsson o Image.FreeType
612ad42008-06-29Martin Nilsson  - Added support for handling monochrome (bitmap) fonts.
431ebd2008-05-09Martin Nilsson 
35c4b12008-05-09Martin Nilsson o Image.Image
612ad42008-06-29Martin Nilsson  - Image object can now be serialized and deserialized with encode_value() and decode_value().
35c4b12008-05-09Martin Nilsson 
612ad42008-06-29Martin Nilsson  - It is possible to convert the colors in an image object to and from YUV (YCrCb) with the new rgb_to_yuv() and yuv_to_rgb() methods.
35c4b12008-05-09Martin Nilsson  o Image.Layer
612ad42008-06-29Martin Nilsson  - It is now possible to get the raw bitmap data of a layer by casting the layer object to a string.
35c4b12008-05-09Martin Nilsson  o Image.PNG - Properly decode cHRM (chrome), sBIT (sbit), gAMA (gamma), pHYs
612ad42008-06-29Martin Nilsson  (physical), oFFs (offset), tIME (time) chunks. - The compression level and strategy when compressing PNG images can be controlled by passing "zlevel" and "zstrategy" options to the encode() method. Available strategies are filtered, huffman, rle and fixed.

b28e2e2008-09-21Martin Nilsson o Java
8ac0b82008-09-21Marcus Comstedt  - If possible, Pike now uses libffi instead of creating our own trampolines. Adding libffi as a bundle is supported. - Added built-in support for SPARC64 trampolines. - The method signature fuzzy-matcher now only considers Pike strings to match formal parameters of type String, Object, Comparable, CharSequence or java.io.Serializable. - When the fuzzy-matcher can not decide on a single method signature, all candidates are now listed in the error message.

92c1842008-05-07Henrik Grubbström (Grubba) 
80e2fe2008-09-08Martin Stjernholm  - Two functions set_charset() and get_charset() have been added to set and query the connection charset. The create() function also takes a "charset" setting in the options mapping. - Improved Unicode support. The MySQL driver now supports (possibly wide) Unicode queries and text return values, handling the connection charset and all encoding/decoding internally. This is enabled by setting the charset to "unicode", or through the new functions set_unicode_encode_mode() and set_unicode_decode_mode(). See their documentation for further details.
b28e2e2008-09-21Martin Nilsson  - Return correct UNDEFINED instead of 0 values for NULL values in

92c1842008-05-07Henrik Grubbström (Grubba) 
612ad42008-06-29Martin Nilsson  - The RCS parser has been rewritten to handle broken RCS data better.
326a9d2007-02-23Martin Nilsson 
e399bc2007-11-11Martin Nilsson o Parser.XML.NSTree - Added add_child_before() and add_child_after() methods to the NSNode object. - Fixed crash bug.
4232ab2008-06-27Martin Nilsson o Parser.XML.Simple
b217b32008-09-21Martin Nilsson  - The autoconvert() function, used to autodetect the character encoding of an XML file and decode it, has been moved from being a method of the Parser.XML.Simple object to being a function in the Parser.XML module.

326a9d2007-02-23Martin Nilsson  o Process
e399bc2007-11-11Martin Nilsson  - The new function spawn_pike() will spawn a Pike process similar to the current one, using the same binary file, master and module paths. - The new function run() is an easy interface that will run a process and return a mapping with all the outputs and exit code. - Process.popen is now able to run in nonblocking mode. If a second argument is provided a file object will be opened with that mode and return, enabling two way communication with the new process. - The system() function has been extended to be able to pass stdin, stdout and stderr arguments to the spawn() call it performs.
71ef5a2007-11-02Henrik Grubbström (Grubba)

43bb262007-11-11Martin Nilsson  o Protocols.HTTP - Added support for httpu and httpmu requests. - Queries will now throw an exception in case of an errno condition. - A new function, do_async_method(), has been added to allow access to low level asynchronous HTTP calls.
43ec872008-06-29Henrik Grubbström (Grubba)  - The http_encode_string() function now knows how to encode UCS-2
43bb262007-11-11Martin Nilsson  characters. o Protocols.HTTP.Server - If accept() fails on the open port, the Port object will continue trying, to support servers with high load.
326a9d2007-02-23Martin Nilsson  o Protocols.HTTP.Query

326a9d2007-02-23Martin Nilsson 
43bb262007-11-11Martin Nilsson  - Fixes for keep alive. o Protocols.LDAP
11b3102008-09-08Martin Stjernholm  - Enabled support for paged queries. - Added more resilience to UTF-8 encode errors. Locale.Charset.DecodeError is thrown for UTF-8 decode exceptions. - Added a connection pool for connection reuse. It is used through get_connection() and return_connection(). - Added some schema handling and use it to fix the UTF-8 conversion to only affect attributes that actually are UTF-8 encoded. - Added client.read(), client.read_attr(), client.get_root_dse_attr(), client.get_basedn(), client.get_scope(), client.get_attr_type_descr(), get_constant_name(), and a bunch of constants for various object oids, attributes, well-known object guids and other things. - Rewrote the search filter parser to handle LDAPv3 extensible matches. It now also throw errors on all syntactic errors (using a new FilterError object), instead of sending a partial filter to the server. It is also possible to compile filters separately through make_filter(), and there is a very simple cache for compiled filters through get_cached_filter(). - Added ldap_encode_string(), ldap_decode_string(), encode_dn_value(), canonicalize_dn(), parse_ldap_url(), client.get_parsed_url(), and client.get_bound_dn(). - Added client.result.fetch_all(). - Added new flag field to client.search() to control various aspects of how results are returned: SEARCH_LOWER_ATTRS lowercases all attribute names. SEARCH_MULTIVAL_ARRAYS_ONLY uses arrays for attribute values only for attributes that might return more than one value. SEARCH_RETURN_DECODE_ERRORS may be used to avoid throwing exceptions on decode errors. - Added client.get_protocol_version(), client.get_supported_controls(), and the possibility to specify controls in client.search(). - Made the result iterator somewhat more convenient: next() now advances one step past the end so the next fetch() returns zero.
12c2682007-11-13Martin Stjernholm 
11b3102008-09-08Martin Stjernholm  - Added client.error_number(), client.error_string(), and client.server_error_string() to make it possible to query errors when no result object is returned.
43bb262007-11-11Martin Nilsson  o Protocols.SNMP The readmsg() method in the protocol object now takes an optional timout argument. o Protocols.XMLRPC The new AsyncClient class implements an asynchronous XMLRPC client.

Sql.Sql db = Sql.Sql("dsn://user:pass@host/database"); - Support for the TDS protocol, used by Sybase and Microsoft SQL server. Sql.Sql db = Sql.Sql("tds://user:pass@host/database"); - Support for the SQLite database added. A raw interface is
b217b32008-09-21Martin Nilsson  available through the SQLite module. FIXME: Syntax?
4f24d62008-06-29Martin Nilsson  Sql.Sql db = Sql.Sql("sqlite://path/to/file");
a2014e2008-07-14Stephen R. van den Berg  - Sql.pgsql. New driver for native PostgreSQL network protocol support. It implements a superset of the existing Postgres driver.

17b7532008-07-30Stephen R. van den Berg  is around 21% faster than the old libpq based Postgres driver
488ce72008-07-24Stephen R. van den Berg  for smaller queries; for large bytea blobs and large texts, it
b212b52008-07-26Stephen R. van den Berg  speeds up even more.
488ce72008-07-24Stephen R. van den Berg 
191f232008-08-16Stephen R. van den Berg  Support for this driver is indicated by PostgresNative appearing in the featurelist, and since it has no library or OS dependencies, it will always be available.
55a93f2008-08-18Stephen R. van den Berg  This driver serves URLs of the form: pgsql:// (plain) and pgsqls:// (SSL). In case the old Postgres driver is disabled, this driver takes over postgres:// transparently as well.
43bb262007-11-11Martin Nilsson  FIXME: mysql o SSL FIXME: client certificates: examples? o Standards.IIM Some bugfixes in parsing Photoshop headers and DOS EPS Binary Headers. o Standards.ISO639_2 Updated with the latest ISO639-2 languages. o Standards.URI - Updated to conform to RFC 3986. - Added methods get_query_variables(), set_query_variables(), add_query_variable() and add_query_variables() to give a better API to to handle query variables. - The new method get_http_query() returns the query part and get_http_path_query() returns both the path and the query, both coded according to RFC 1738. o Standards.UUID - Added support for UUID version 5; name based with SHA hash, which can be generated from the make_version5 function. - An UUID object can now be used as namespace in the second argument to make_version3 as well as the new make_version5. o Standards.XML.Wix FIXME
2f5dd42008-06-29Martin Nilsson o Stdio - Stdio.cp can now work recursively in a directory tree. It will also keep the permissions of files it copies. - Added Stdio.recursive_mv which works on every OS and also when the destination isn't on the same filesystem as the source. - Added more symbolc default termcap/terminfo bindings to Stdio.Readline. - Improved support for Terminfo on NetBSD. - read_file(), read_bytes(), write_file() and append_file() will may now throw exceptions on uncommon errors such as when write_file is unable to write all its data.

afa4822006-12-29Martin Nilsson 
2f5dd42008-06-29Martin Nilsson New modules / classes / methods added -------------------------------------
afa4822006-12-29Martin Nilsson 
5a46c72008-06-29Per Hedbor o Fuse FUSE (Filesystem in USErspace) provides a simple interface for userspace programs to export a virtual filesystem to the Linux kernel (and some other OS:es). FUSE also aims to provide a secure method for non privileged users to create and mount their own filesystem implementations. This module implements the needed interfaces to make it possible to write a FUSE filesystem in Pike.
326a9d2007-02-23Martin Nilsson o ADT.List
5a46c72008-06-29Per Hedbor  A simple linked list of values.
b28e2e2008-09-21Martin Nilsson  FIXME: Example
5a46c72008-06-29Per Hedbor 
71ef5a2007-11-02Henrik Grubbström (Grubba) o ADT.Trie
b28e2e2008-09-21Martin Nilsson  FIXME
afa4822006-12-29Martin Nilsson o ADT.Set
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  ADT.Set implements a datatype for sets. These sets behave much like multisets, except that they are restricted to containing only one instance of each member value. From a performance viewpoint, it is probably more efficient for a Pike program to use mappings to serve as sets, rather than using an
b28e2e2008-09-21Martin Nilsson  ADT.Set, so ADT.Set is mainly provided for the sake of completeness
afa4822006-12-29Martin Nilsson  and code readability.
e399bc2007-11-11Martin Nilsson o Arg
92c1842008-05-07Henrik Grubbström (Grubba) 
b28e2e2008-09-21Martin Nilsson  The new argument parser module allows for Getopt style argument
19a6f32008-05-03Martin Nilsson  parsing, but with a much simpler and object oriented API. class Parser { inherit Arg.Options; Opt verbose = NoOpt("-v")|NoOpt("--verbose")|Env("VERBOSE"); Opt name = HasOpt("-f")|HasOpt("--file")|Default("out"); Opt debug = MaybeOpt("-d")|MaybeOpt("--debug"); } void main(int argc, array(string) argv) { Parser p = Parser(argv); werror("name: %O, verbose: %O, debug: %O\n", p->name, p->verbose, p->debug); } A more simplistic interface is also available for smaller hacks and programs. void main(int argc, array(string) argv) { mapping opts = Arg.parse(argv); argv = opts[Arg.REST]; }
e399bc2007-11-11Martin Nilsson 
6b901e2008-07-22Martin Stjernholm o GSSAPI Implements Pike access to GSS-API v2 as specified in RFC 2743. This API is used to authenticate users and servers, and optionally also to encrypt communication between them. The API is generic and can be used without any knowledge of the actual implementation of these security services, which is typically provided by the operating system. The most common implementation is Kerberos, which means that the main benefit of this API is to allow clients and servers to authenticate each other using Kerberos, thereby making single sign-on possible in a Kerberized environment.
0d73d72008-06-29Martin Nilsson o GTK2
2427442008-06-29Per Hedbor  Wrapper for the GTK2 library. Not yet 100% completed, but usable.

afa4822006-12-29Martin Nilsson o Protocols.DNS_SD
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  This module provides an interface to DNS Service Discovery. The functionality of DNS-SD is described at <http://www.dns-sd.org/>. Using the Proctocols.DNS_SD.Service class a Pike program can announce services, for example a web site or a database server, to computers on the local network. When registering a service you need to provide the service name. service type, domain and port number. You can also optionally specify a TXT record. The contents of the TXT record varies between different services; for example, a web server can announce a path to a web page, and a printer spooler is able to list printer features such as color support or two-sided printing. The service is registered on the network for as long as the instance of the Service class is valid. o Bittorrent.Tracker
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  Bittorrent tracker with support for scraping and UDP extension. o Protocols.HTTP.Server.Proxy
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  A simple HTTP proxy. o Standards.TLD
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  Country domains and other TLDs according to IANA. Useful when parsing log information or providing live information about clients connecting to your server. o Tools.Shoot
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  Several new tests have been added to benchmark and improve on
66f21a2008-05-10Henrik Grubbström (Grubba)  various aspects of Pike. ReplaceParallel and ReplaceSerial measure the times it takes to replace multiple substrings of a string in a
afa4822006-12-29Martin Nilsson  single call to replace and with subsequent calls. TagRemoveArraySscanf, TagRemoveDivide, TagRemoveLoop, TagRemoveParserHTML, TagRemovePCRE, TagRemoveSearch and
66f21a2008-05-10Henrik Grubbström (Grubba)  TagRemoveSscanf measure different methods of completing the same task; to remove XML tags from a string.
afa4822006-12-29Martin Nilsson  o Web.CGI
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  Provides a CGI interface on the callee side. Retrieves information from environment variables and populates the variables in the Request object.

2f5dd42008-06-29Martin Nilsson 
afa4822006-12-29Martin Nilsson Incompatible changes
2f5dd42008-06-29Martin Nilsson --------------------
afa4822006-12-29Martin Nilsson  These incompatible changes can be solved by adding #pike 7.6 to your source file or starting Pike with -V7.6.
482f8b2008-06-30Martin Nilsson o main() environment The main() method will no longer be given the environment as a mapping as third argument. Use an explicit call to getenv() instead.
afa4822006-12-29Martin Nilsson o Array.transpose_old
92c1842008-05-07Henrik Grubbström (Grubba) 
66f21a2008-05-10Henrik Grubbström (Grubba)  This function has been removed.
afa4822006-12-29Martin Nilsson  o _Charset
92c1842008-05-07Henrik Grubbström (Grubba) 
66f21a2008-05-10Henrik Grubbström (Grubba)  The parts of this internal module that were written in Pike have moved to Locale.Charset.
92c1842008-05-07Henrik Grubbström (Grubba) 
e399bc2007-11-11Martin Nilsson o Crypto
92c1842008-05-07Henrik Grubbström (Grubba)  The old crypto functions from Pike 7.4 have been removed. These
e399bc2007-11-11Martin Nilsson  functions produced a warning when used in Pike 7.6.
afa4822006-12-29Martin Nilsson o Debug.describe_program
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  The API for this debug function has changed. o Image.Image
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  The functions select_colors(), map_closest(), map_fast() and map_fs() has been removed. Use Image.Colortable operations instead. o Parser.XML
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  The XML parsers are now stricter in verifying the correctness of the XML. The function compat_allow_errors can be called in the create method of the Parser.XML.Simple and Parser.XML.Validating (with "7.6" as argument for 7.6 compatibility). Parser.XML.Tree can be created with PARSE_COMPAT_ALLOW_ERRORS_7_6 as flag. o Protocols.LDAP.client
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  The "dn" field wasn't properly utf-8 decoded in 7.6 and earlier. If your application does it yourself, you need to use the compatibility version of this class. o spider.XML
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  The spider module no longer contains the XML parser. The functions isbasechar(), iscombiningchar(), isdigit(), isextender(), isfirstnamechar(), ishexchar(), isidiographic(), isletter(),
66f21a2008-05-10Henrik Grubbström (Grubba)  isnamechar() and isspace() have also been moved to the Parser module.
afa4822006-12-29Martin Nilsson  o Sql.Sql
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  Pike will no longer create a .column entry in SQL query responses if there is no table name. o Standards.UUID
92c1842008-05-07Henrik Grubbström (Grubba)  Functions new() and new_string() have been removed. Use
afa4822006-12-29Martin Nilsson  make_version1(-1)->encode() and make_version1(-1)->str() instead. o Stdio
92c1842008-05-07Henrik Grubbström (Grubba) 
afa4822006-12-29Martin Nilsson  The functions read_file(), read_bytes(), write_file() and
92c1842008-05-07Henrik Grubbström (Grubba)  append_file() now always throw errors on error conditions, to allow easier use as errno doesn't have to be checked. read_file() and read_bytes() still return 0 if the file does not exist.
326a9d2007-02-23Martin Nilsson 
92c1842008-05-07Henrik Grubbström (Grubba) o The modules Mird, Perl and Ssleay have been removed.
e399bc2007-11-11Martin Nilsson 
2f5dd42008-06-29Martin Nilsson C level module API ------------------ o Improved support for embedding. Several declarations and definitions (most notably the debug and runtime flags) have moved from main.h to pike_embed.h, in an attempt to add support for embedding. o Major compiler API cleanups. The Pike compiler is now executing in a pike function context (rather than in an efun context), and it is possible to customize some of its behaviour via inherit (rather than via handler objects). As a consequence the compiler is now much closer to being thread-safe. o The global variable next_timeout is no more. It has been replaced by a backend-specific variable. Added backend_lower_timeout() for accessing the new variable. This fixes issues GTK, GTK2 and sendfile had with the new backend implementation. NOTE! C-API incompatibility! NOTE! Changed the argument for backend callbacks!
2427442008-06-29Per Hedbor  The argument is now a struct Backend_struct * when called at entry (was NULL). The argument is now NULL when called at exit (was 1).
2f5dd42008-06-29Martin Nilsson  o Pike_fp->context Pike_fp->context is now a pointer to the current struct inherit rather than a copy of it. This allows for easier access to inherited symbols in C-code. o Inherit level argument added to several object handling functions. In order to implement subtyping of objects, an extra argument "inherit_level" has been added to many object indexing related functions.
2427442008-06-29Per Hedbor o .cmod:
2f5dd42008-06-29Martin Nilsson  Voidable pointer types are no longer promoted to mixed. o Support for class symbols with storage in parent scope. Also added support for aliased symbols.
482f8b2008-06-30Martin Nilsson o Machine code backend for PPC64 FIXME o Objectiv-C embedding framwork FIXME
56398b2008-06-29Per Hedbor o Added %c and %C to get_all_args to get char * without NUL characters (no 0 valued characters inside the string). %c: char * Only narrow (8 bit) strings without NUL. This is identical to %s. %C: char * or NULL Only narrow (8 bit) strings without NUL, or 0

2427442008-06-29Per Hedbor Building and installing -----------------------
2f5dd42008-06-29Martin Nilsson 
e13e682008-09-21Martin Stjernholm o Dynamic modules now become DLLs on Windows. This means the homegrown module loader is no longer used, but it also means some DLL limitations: - PMOD_EXPORT is now required to allow access to an identifier in the pike core. - DLLs have to be recompiled too if pike.exe is recompiled. The primary motivation for this change is to work with the new library tracking (so-called "side-by-side assemblies") in Visual C++ 2005 and later.
2f5dd42008-06-29Martin Nilsson o Added ABI selection. It's now possible to select whether to compile in 32bit or 64bit mode at configure time by using the --with-abi option.
b28e2e2008-09-21Martin Nilsson o MinGW builds. It's now possible to build Pike in MinGW on windows computers from source distributions.

abfd1b2008-06-29Per Hedbor New simplified method to write external C/C++ modules
2f5dd42008-06-29Martin Nilsson -----------------------------------------------------
abfd1b2008-06-29Per Hedbor  It's now suggested that you do not use the fairly complex 'pike internal' style of external modules (configure.in with AC_MODULE_INIT etc). It's also no longer required that you have a configure script to use pike -x module. Instead simply locate the includefiles using 'pike -x cflags', and convert .cmod to .c files using 'pike -x precompile'. An example rather minimal 'pike -x module' compatible Makefile, without a configure script, using .cmod format files for a simple local module: | CC=gcc | CFLAGS := -O9 -fweb -shared -Wall $(CFLAGS) $(shell $(PIKE) -x cflags) -g | LD=$(CC) -shared -lGL | | all: Spike.so | | install: Spike.so | cp $< $(MODULE_INSTALL_DIR) | | Spike.so: Spike.o | $(LD) -o Spike.so Spike.o $(LDFLAGS) | | Spike.o: Spike.c | | Spike.c: Spike.cmod | $(PIKE) -x precompile $< > $@ It's usually OK not to use pike -x module at all, but it will pass on a few extra variables to your make (and configure script): PIKE: How to start the pike interpreter used running pike -x module MODULE_INSTALL_DIR: Where modules goes LOCAL_MODULE_PATH: Alternative (user local) module location
