3a6fd92013-10-08Per Hedbor Pike 8: Changes since Pike 7.8 (scratch area for future release notes)
2ac4992011-03-09Martin Stjernholm ----------------------------------------------------------------------
b61e1b2014-07-25Henrik Grubbström (Grubba) 
3521322013-11-02Per Hedbor New language features ---------------------
0d74632013-11-02Per Hedbor 
3521322013-11-02Per Hedbor o Added a way to access the local, and not the overloaded, implementation of a symbol.
10234d2013-11-08Henrik Grubbström (Grubba)  As an example, given the classes: | class Test | { | int a( ) { return 1; } | int b( ) { return local::a(); } // New | int c( ) { return a(); } | } | | class Test2 | { | int a() { return 42; } | } Both Test()->b() and Test2()->b() will return 1, but Test2()->a() and Test2()->c() will return 42.
3521322013-11-02Per Hedbor 
0492422013-11-03Per Hedbor o Added new syntax that can be used to return the current object as if it was a class it is inheriting The syntax is X::this, where X is the inherited class. The returned object will not include any symbols not available in the class X, but your overloaded methods (and other identifiers) will be the ones returned when the object is indexed.
3521322013-11-02Per Hedbor o Added a way to easily inherit the implementation of a subclass in an inheriting class. | inherit ::this_program
10234d2013-11-08Henrik Grubbström (Grubba)  The syntax refers to the previous definition of the current class in the inherited class, and is typically used with inherit like:
3521322013-11-02Per Hedbor  | inherit Foo; | | // Override the Bar inherited from Foo. | class Bar {
10234d2013-11-08Henrik Grubbström (Grubba)  | // The new Bar is based on the implementation of Bar in Foo.
3521322013-11-02Per Hedbor  | inherit ::this_program; | // ... | }
10234d2013-11-08Henrik Grubbström (Grubba) o Added new syntax for referring to and naming inherits. | inherit "foo.pike"; | inherit "foo/bar/baz.pike" : "foo/bar"; | // ... | "foo.pike"::foo(); | "foo/bar"::baz(); o Lookup of named inherits now also looks in indirect inherits. | class A { int fun() {} } | class B { inherit A; } | class C { | inherit B; | // ... | // The function fun may here be referred to as any of: | B::A::fun(); | B::fun(); | A::fun(); // New.
cb784a2013-11-02Per Hedbor o Implemented the variant keyword.
dbcab02013-11-03Per Hedbor  The keyword was present before, but did not actually do anything
cb784a2013-11-02Per Hedbor  useful.
3521322013-11-02Per Hedbor  This is used to do function overloading based on the argument types. As an example:
54fe982013-11-01Per Hedbor  | class Test1 { int b(); } | class Test2 { int a(); } | | class Foo | { | variant string foo( object q ){ return "Genericfoo"; } | variant string foo( Test1 x ) { return "Test 1"; } | variant string foo( Test2 x ) { return "Test 2"; } | | variant string bar( int(0..0) s ) { return "0"; } | variant float bar( int(1..1) s ) { return 1.0; } | variant int bar( int(2..2) s ) { return 2; } | }
10234d2013-11-08Henrik Grubbström (Grubba)  A common use-case is functions that return different types depending on the arguments, such as getenv:
54fe982013-11-01Per Hedbor 
10234d2013-11-08Henrik Grubbström (Grubba)  | string|mapping(string:string) getenv( string|void variable );
0492422013-11-03Per Hedbor 
10234d2013-11-08Henrik Grubbström (Grubba)  can now be rewritten as
3521322013-11-02Per Hedbor 
10234d2013-11-08Henrik Grubbström (Grubba)  | variant string getenv( string variable ); | variant mapping(string:string) getenv( );
3521322013-11-02Per Hedbor 
10234d2013-11-08Henrik Grubbström (Grubba)  which gives significantly better type-checking.
3521322013-11-02Per Hedbor 
dbcab02013-11-03Per Hedbor o The type-checker has been rewritten.
3521322013-11-02Per Hedbor  Mainly it is now much better at finding type errors, and most error messages are more readable.
54fe982013-11-01Per Hedbor 
0492422013-11-03Per Hedbor o Allow '.' to be used as an index operator in the few places it did
54fe982013-11-01Per Hedbor  not work before.
0d74632013-11-02Per Hedbor o "Safe" index
0492422013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  Copied from a popular extension to other C-like languages.
54fe982013-11-01Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  X[?ind] is equivalent to ((auto _ = X),(_ && _[ind])) while X?->ind is equivalent to ((auto _ = X),(_ && _->ind))
0492422013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  The main use is 'deep indexing' where some elements can be 0:
54fe982013-11-01Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  | request_id?->user?->misc?->x
0492422013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  vs | request_id && request_id->user && request_id->user->misc | && request_id->user->misc->x
54fe982013-11-01Per Hedbor 
0e166f2013-11-02Martin Nilsson o Added the '?:' operator for compatibility with other C-like
0492422013-11-03Per Hedbor  languages. It is identical to '||' in pike.
0d74632013-11-02Per Hedbor  o The && operator changed, when doing A && B, and A is false, keep A
cb784a2013-11-02Per Hedbor  instead of returning 0.
0492422013-11-03Per Hedbor 
0d74632013-11-02Per Hedbor  This is especially useful then A is not actually 0, but an object that evaluates to false, or UNDEFINED.
f8adc02013-11-16Henrik Grubbström (Grubba) o Fixed symbol resolution with deep inherits and mixins.
c391462014-05-06Per Hedbor o Added multi-character character constants. 'ILBM' is equivalent to (('I'<<24)|('L'<<16)|('B'<<8)|'M'). Unlike how it works in some C compilers the native byte order is never relevant.
f5b27e2014-07-21Per Hedbor o Added new syntax for literal-string constats #{, #( and #[ starts a literal string, and it is ended by the corresponding end marker: #}, #) and #] respectively. No character is modified at all inside the literal string, including newlines, \ " and '. So, the string #["\n\'##] will be equivalent to "\"\\n\\'#". The main usecase is to write code in code: | string code = #[ | void main(int c, array v) { | string x = ""; | foreach( v[1..], string elm ) | x += reverse(elm)+","; | write("Testing: %s\n", reverse( x )); | #]; The three different start/end markers might be useful if you write code in code in code, since there is no way to quote the start/end markers.
75d6562013-11-15Henrik Grubbström (Grubba) 
ec0bce2014-07-21Per Hedbor o Added a shorthand syntax for integer rages: xbit, where x is a number between 1 and 31. This can be used as an example to indicate that a string is 8 bits wide only: string(8bit) This is equivalent to the range (0..255) but can be easier to parse. Similarily int(1bit) is an alias for 'bool', and int(12bit) is the same as int(0..4095).
b61e1b2014-07-25Henrik Grubbström (Grubba) 
0492422013-11-03Per Hedbor New preprocessor features -------------------------
0d74632013-11-02Per Hedbor 
0492422013-11-03Per Hedbor o Support for the ", ##__VA_ARGS__" cpp feature.
3521322013-11-02Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  This makes the ‘##’ token paste operator have a special meaning when placed between a comma and a variable argument. If you write | #define err(format, ...) f(debug)werror("ERROR: "+format, ##__VA_ARGS__)
0492422013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  and the variable argument is left out when the err macro is used, then the comma before the ‘##’ will be deleted. This does not happen if you pass an empty argument, nor does it happen if the token preceding ‘##’ is anything other than a comma.
3521322013-11-02Per Hedbor 
ce261a2014-08-26Per Hedbor o The define __COUNTER__ has been added. It is a unique integer value, the first time the macro is expaded it will be 1, the next time 2 etc.
0492422013-11-03Per Hedbor o The preprocessor can now be run with a cpp prefix feature.
75d6562013-11-15Henrik Grubbström (Grubba)  This is currently used by the precompiler to avoid two levels of preprocessing, one using "#cmod_" as the prefix and the other "#".
3521322013-11-02Per Hedbor 
0d74632013-11-02Per Hedbor o Dynamic macros
75d6562013-11-15Henrik Grubbström (Grubba)  You can now add programatic macros. There is currently no syntax that can be used to define these while compiling code, but you can add them from one program before compiling plug-ins/modules. The main use is macros like DEBUG(...) and IFDEBUG() that would expand to something if a debug setting is enabled in the module but nothing otherwise, or, to take an actual example from the Opera Mini source code: | add_predefine( "METRIC()", | lambda( string name, string ... code ) | { | string type = type_of( code ); | string aggregate = aggregate_of( code ); | string format = format_of( code ); | code -= ({ 0 }); | return replace( base_metric_class, | (["ID":(string)next_metric_id++, | "NAME":stringify(name), | "TYPE":type, | "AGGREGATE":aggregate, | "FORMAT":format, | "CODE":make_value_function(code), | ])); | }); That is, a macro that needs does some calculations, and rewrite the code more than is possible in normal macros.. This one expands something along the lines of | METRIC("requests", Summarize, PerSecond, | floating_average_diff(requests)); into | class Metric_requests_01 | { | inherit Server.Metric; | constant name = "transcoder:requests"; | constant type = Float; | constant format = PerSecond; | constant aggregate = Summarize; | | float value() { | return floating_average_diff(requests); | } | }
54fe982013-11-01Per Hedbor 
5eb2d62014-02-17Martin Nilsson o Dependency declarations It is now possible to use the CPP directive #require to specify a condition that must be true for the file to be seen by the resolver. This would typically be the inherited C part of a module or a system call. | #require constant(__WebKit) | inherit __WebKit;
56d0052013-11-02Martin Nilsson 
0e166f2013-11-02Martin Nilsson Optimizations
56d0052013-11-02Martin Nilsson -------------
54fe982013-11-01Per Hedbor  o New significantly faster block allocator
75d6562013-11-15Henrik Grubbström (Grubba) 
0727862013-11-02Martin Nilsson  The free in the old one was O(n^2), which means that as an example
0d74632013-11-02Per Hedbor  creating a lot of objects and then free:ing them mainly used CPU in the block allocator. This fix changed the ordo of one of the tests that did that very
0727862013-11-02Martin Nilsson  thing (binarytrees) from O(n^2) to O(n), and as such is more than a
cb784a2013-11-02Per Hedbor  simple percentual speedup in some cases, but it always improves the performance some since the base speed is also faster.
0d74632013-11-02Per Hedbor 
54fe982013-11-01Per Hedbor o Power-of-two hashtables are now used for most hashtables
0d74632013-11-02Per Hedbor  This speeds up mappings and other hashtables a few percent, and also simplifies the code. o Significantly changed x86-32 and an entirely new AMD64/x86-64
dbcab02013-11-03Per Hedbor  machine-code compilation backend
0492422013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  The main feature with the x86-32 edition is that it is now using normal function call mechanics, which means that it now works with modern GCC:s.
0d74632013-11-02Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  The x86-64 backends has been rewritten so that it is easier to add
22755e2014-08-16Per Hedbor  new instructions (x86-64) and opcodes (pike) to it, and it is significantly more complete than the x86-32 one.
0d74632013-11-02Per Hedbor  o Svalue type renumbering
75d6562013-11-15Henrik Grubbström (Grubba)  PIKE_T_INT is now type #0, which makes certain things significantly faster.
0d74632013-11-02Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  As an example, clearing of object variables is now done automatically when the object is created since all object memory is set to 0.
0d74632013-11-02Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  The same thing happens when clearing values on the stack.
0d74632013-11-02Per Hedbor 
ec0bce2014-07-21Per Hedbor o Svalue type/subtype setting changed This halves the number of instructions used to push a value on the stack in most cases. The speedup is not large, but noticeable. o And on a related note, we now lie to the compiler about the const:ness of the Pike_interpreter_pointer variable. This significantly simplifies the code generated by the C-compiler for stack manipulation functions, the stack pointer is now only loaded once per code block, instead of once per stack operation. This saves a lot of code when using the stack multiple times in a function, and should be safe enough, albeit somewhat unconventional. If nothing else the binary size shrunk by about 5%.
54fe982013-11-01Per Hedbor o string(x..y) (constant) types
75d6562013-11-15Henrik Grubbström (Grubba)  The strings now keep track of the min/max values in addition to two new flags: all-uppercase and all-lowercase.
0d74632013-11-02Per Hedbor 
cb784a2013-11-02Per Hedbor  | > typeof("foo"); | (1) Result: string(102..111)
75d6562013-11-15Henrik Grubbström (Grubba)  This is used to optimize certain operations, lower_case, upper_case, search and string_has_null for now. It could be added to other places in the future as well.
cb784a2013-11-02Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  The fairly common case where you are doing lower_case or upper_case on an already lower or uppercase strings is now significantly faster.
0d74632013-11-02Per Hedbor 
54fe982013-11-01Per Hedbor o Several other optimizations to execution speed has been done
75d6562013-11-15Henrik Grubbström (Grubba) 
0d74632013-11-02Per Hedbor  + object indexing (cache, generic speedups)
75d6562013-11-15Henrik Grubbström (Grubba) 
0d74632013-11-02Per Hedbor  + lower_apply, changes to apply in general
dbcab02013-11-03Per Hedbor  Taken together these individually small optimizations speeds up at
0e166f2013-11-02Martin Nilsson  least pike -x benchmark more than 5%.
75d6562013-11-15Henrik Grubbström (Grubba) 
dbcab02013-11-03Per Hedbor  + A lot of opcodes implemented in machine-code for x86-64
0d74632013-11-02Per Hedbor  This speed up the loop benchmarks close to a factor of 3. But then again, most real code is nothing like that benchmark.
75d6562013-11-15Henrik Grubbström (Grubba) 
0d74632013-11-02Per Hedbor  + Several new opcodes added As an example an observation was that most branch_if_zero is followed by an is_eq, is_lt or is_gt or similar. Those opcodes
cb784a2013-11-02Per Hedbor  always return 1 or 0. So, two new opcodes, quick_branch_if_zero and quick_branch_if_non_zero were added that map directly to three
0e166f2013-11-02Martin Nilsson  x86-64 opcodes, there is no need to check the types, do a real pop_stack etc.
54fe982013-11-01Per Hedbor 
ec0bce2014-07-21Per Hedbor  + Demacroified some code, resulting in smaller code-size This makes things faster, it is often better to branch to a small block of code than to have it inlined in a lot of different locations on modern architectures.
04ecc62013-11-02Per Hedbor o Faster hash-function for strings
75d6562013-11-15Henrik Grubbström (Grubba) 
97b3fe2013-11-02Arne Goedeke  + Also siphash24 was added and is used in case the string hash table becomes inefficient
04ecc62013-11-02Per Hedbor 
b61e1b2014-07-25Henrik Grubbström (Grubba) 
240fea2013-11-02Per Hedbor Deprecated features and modules -------------------------------
0492422013-11-03Per Hedbor o Tools.PEM and Tools.X409 deprecated
75d6562013-11-15Henrik Grubbström (Grubba)  Use the corresponding modules in Standards.
240fea2013-11-02Per Hedbor  o The built in sandbox is now deprecated
75d6562013-11-15Henrik Grubbström (Grubba)  Unless somebody wants to take ownership of the feature and keep it up to date the security system will be removed in the next stable release.
f8adc02013-11-16Henrik Grubbström (Grubba) o The compiler now warns about switch statements where the cases aren't enumerable, since these will generate random failures if the code is read from a dump.
44ca4b2013-11-17Per Hedbor o strlen() now only accepts strings
22755e2014-08-16Per Hedbor o Gdbm.gdbm is now known as Gdbm.DB o Yabu.db and Yabu.table renamed to Yabu.DB and Yabu.Table o The keyword 'static' will now generate deprecation warnings.
240fea2013-11-02Per Hedbor 
cb784a2013-11-02Per Hedbor Removed features and modules ----------------------------
0d74632013-11-02Per Hedbor 
54fe982013-11-01Per Hedbor o Removed facets
75d6562013-11-15Henrik Grubbström (Grubba)  The optional (and not enabled by default) support for facet classes has been removed, since it was only partially done and not really used.
3521322013-11-02Per Hedbor  o It is no longer possible to compile pike without libgmp.
75d6562013-11-15Henrik Grubbström (Grubba)  Bignums are now a required language feature
3521322013-11-02Per Hedbor 
02f8152013-11-02Henrik Grubbström (Grubba) o The old low-level 'files' module has been renamed to _Stdio
3521322013-11-02Per Hedbor  o 'GTK' is now GTK2, not GTK1 unless the system has no GTK2 support. o Locale.Charset
75d6562013-11-15Henrik Grubbström (Grubba)  The charset module is now available on the top level as 'Charset'
22755e2014-08-16Per Hedbor o The ancient syntax for arrays (string * was an alias for array(string)) has now been removed completely.
ec80082014-08-24Martin Nilsson o Compatibility for pike versions before 7.4 is no longer available.
22755e2014-08-16Per Hedbor  o decode_value can no longer decode programs using the 'old style' program encoding. Since the format has been deprecated since feb 2003, and those programs could not be decoded anyway due to other issues it is not much of a loss.
3521322013-11-02Per Hedbor 
0e166f2013-11-02Martin Nilsson New modules -----------
3521322013-11-02Per Hedbor  o Pike.Watchdog
75d6562013-11-15Henrik Grubbström (Grubba) 
3521322013-11-02Per Hedbor  A Watchdog that ensures that the process is not hung for an extended period of time. The definition of 'hung' is: Has not used the default backend.
0492422013-11-03Per Hedbor 
3521322013-11-02Per Hedbor  To use it simply keep an instance of the watchdog around in your application:
0492422013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  | Pike.Watchdog x = Pike.Watchdog( 5 ); // max 5s blocking
0492422013-11-03Per Hedbor 
3521322013-11-02Per Hedbor  An important and useful side-effect of this class is that the process will start to respond to kill -QUIT by printing a lot of debug information to stderr, including memory usage, and if pike is compiled with profiling, the CPU used since the last time kill -QUIT was called.
c8ae882013-11-03Per Hedbor o Crypto.Password
75d6562013-11-15Henrik Grubbström (Grubba)  A module that can be used to verify and create passwd/ldap style password hashes. It tries to support most common password hashing schemes.
c8ae882013-11-03Per Hedbor 
3521322013-11-02Per Hedbor o Debug.Profiling
75d6562013-11-15Henrik Grubbström (Grubba)  Tools useful for collecting and format for output the profiling information generated when pike is compiled --with-profiling.
3521322013-11-02Per Hedbor 
a4f7d92013-11-02Per Hedbor o NetUtils
75d6562013-11-15Henrik Grubbström (Grubba)  This module contains a lot of functions useful for the storage and processing of network addresses, it supports IPv4 and IPv6.
a4f7d92013-11-02Per Hedbor 
1447e72011-12-13Tobias S. Josefowitz o Added ADT.CritBit module
75d6562013-11-15Henrik Grubbström (Grubba)  Mapping-like key-sorted data structures for string, int and float-keys (ADT.CritBit.Tree, ADT.CritBit.IntTree, ADT.CritBit.FloatTree). Implemented in C.
225dd12013-11-01Per Hedbor 
54fe982013-11-01Per Hedbor o Standards.BSON
75d6562013-11-15Henrik Grubbström (Grubba)  A new module for working with BSON serialized data. See http://bsonspec.org/
54fe982013-11-01Per Hedbor 
225dd12013-11-01Per Hedbor o Geography.GeoIP
75d6562013-11-15Henrik Grubbström (Grubba)  Does geolocation of IPv4-numbers using databases from maxmind.com or software77.net
54fe982013-11-01Per Hedbor 
7876c92013-11-01Per Hedbor o Protocols.WebSocket
75d6562013-11-15Henrik Grubbström (Grubba)  An implementation of the WebSocket (RFC 6455) standard, both server and client
225dd12013-11-01Per Hedbor  o Image.WebP
75d6562013-11-15Henrik Grubbström (Grubba)  Encoder and decoder for the WEBP image format. More information about the format can be found on https://developers.google.com/speed/webp/
225dd12013-11-01Per Hedbor 
54fe982013-11-01Per Hedbor o Serializer
225dd12013-11-01Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  APIs useful to simplify serialization and deserialization of objects Mainly it allows you to easily iterate over the object variables, including the private ones. + Serializer.Encodable A class that can be inherit to make an object easily serializable using encode_value.

dbcab02013-11-03Per Hedbor o Filesystem.Monitor and the low level System.Inotify + System.FSEvents
0d74632013-11-02Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  Basic filesystem monitoring.
0d74632013-11-02Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  This module is intended to be used for incremental scanning of a filesystem. Supports FSEvents on MacOS X and Inotify on Linux to provide low overhead monitoring; other systems currently use a less efficient polling approach.
225dd12013-11-01Per Hedbor 
54fe982013-11-01Per Hedbor o Mysql.SqlTable
0492422013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  This class provides some abstractions on top of an SQL table. At the core it is generic for any SQL database, but the current implementation is MySQL specific on some points, notably the semantics of AUTO_INCREMENT, the quoting method, knowledge about column types, and some conversion functions. Hence the location in the Mysql module.
0492422013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  Among other things, this class handles some convenient conversions between SQL and pike data types
225dd12013-11-01Per Hedbor 
54fe982013-11-01Per Hedbor o Parser.CSV
75d6562013-11-15Henrik Grubbström (Grubba)  This is a parser for line oriented data that is either comma, semi-colon or tab separated. It extends the functionality of the Parser.Tabular with some specific functionality related to a header and record oriented parsing of huge datasets.
54fe982013-11-01Per Hedbor 
225dd12013-11-01Per Hedbor o ZXID
0492422013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  ZXID is a library that implements SAML 2.0, Liberty ID-WSF 2.0 and XACML 2.0. This module implements a wrapper for ZXID. The interface is similar to the C one, but using generally accepted Pike syntax.
225dd12013-11-01Per Hedbor 
0e166f2013-11-02Martin Nilsson o Git
75d6562013-11-15Henrik Grubbström (Grubba)  A module for interacting with the Git distributed version control system.
225dd12013-11-01Per Hedbor  o Val
75d6562013-11-15Henrik Grubbström (Grubba)  This module contains special values used by various modules, e.g. a Val.null value used both by Sql and Standards.JSON. In many ways these values should be considered constant, but it is possible for a program to replace them with extended versions, provided they don't break the behavior of the base classes defined here. Since there is no good mechanism to handle such extending in several steps, pike libraries should preferably ensure that the base classes defined here provide required functionality directly.
54fe982013-11-01Per Hedbor 
5c38332013-11-03Henrik Grubbström (Grubba) o __builtin
75d6562013-11-15Henrik Grubbström (Grubba)  The __builtin module is now a directory module, so that it can provide a suitable namespace for code written in Pike intended for being inherited from modules written in C (cf precompile).
5c38332013-11-03Henrik Grubbström (Grubba) 
56d0052013-11-02Martin Nilsson

89a3182013-11-02Martin Nilsson 
ec0bce2014-07-21Per Hedbor o Both sscanf and sprintf can now handle binary floats in little endian format %-8F would be a 64 bit IEEE float binary value in little endian order.
0492422013-11-03Per Hedbor o Image.JPEG
75d6562013-11-15Henrik Grubbström (Grubba)

ec0bce2014-07-21Per Hedbor o Image.BMP now supports some more BMP:s. + Added support for vertical mirroring (images starting at the bottom left) + Added support for 32-bit (non-alpha) BMP:s.
89a3182013-11-02Martin Nilsson o String.Buffer
75d6562013-11-15Henrik Grubbström (Grubba)  String.Buffer can now add the storage from a different String.Buffer object with the add() method.
89a3182013-11-02Martin Nilsson 
75d6562013-11-15Henrik Grubbström (Grubba)  It is possible to add sprintf-formatted data to a String.Buffer object by calling the sprintf() method. This function works just as the normal sprintf(), but writes to the buffer instead. The new method addat() allows for writing into the buffer at any position.
89a3182013-11-02Martin Nilsson 
e8c88c2014-08-26Stephen R. van den Berg  It is possible to address (and update) single characters in a Buffer using []. It is possible to extract a new Buffer (copy) from an existing Buffer using the [..] range operator.
7234352014-08-27Stephen R. van den Berg  It is possible to compare two Buffers or a Buffer and a string directly using the == operator.
e8c88c2014-08-26Stephen R. van den Berg  A new method cut() allows you to cut and copy, or simply delete and contract data from an existing Buffer.
ec0bce2014-07-21Per Hedbor o String.range(str) This returns the minimum and maximum character value in the string. The precision is only 8 bits, so for wide strings only character blocks are known.
3bd5e22014-07-24Henrik Grubbström (Grubba) o String.filter_non_unicode(str)
ec0bce2014-07-21Per Hedbor  This function replaces all non-unicode characters in a pike string
3bd5e22014-07-24Henrik Grubbström (Grubba)  with 0xfffd.
ec0bce2014-07-21Per Hedbor 
cb784a2013-11-02Per Hedbor o SDL.Music added to SDL.
75d6562013-11-15Henrik Grubbström (Grubba)  Allows the playback of audio/music files. Requires the SDL_mixed library.
cb784a2013-11-02Per Hedbor 
225dd12013-11-01Per Hedbor o System.TM
75d6562013-11-15Henrik Grubbström (Grubba)  Low-level wrapper for struct tm. This can be used to do (very) simple calendar operations. It is, as it stands, not 100% correct unless the local time is set to GMT, and does mirror functionality already available in gmtime() and localtime() and friends, but in a (perhaps) easier to use API.
225dd12013-11-01Per Hedbor 
cb784a2013-11-02Per Hedbor o decode_value now throws the error object Error.DecodeError.
75d6562013-11-15Henrik Grubbström (Grubba)  Useful to catch format errors in the decode string.
56d0052013-11-02Martin Nilsson 
cb784a2013-11-02Per Hedbor o Process.daemon
75d6562013-11-15Henrik Grubbström (Grubba)  The daemon() function is for programs wishing to detach themselves from the controlling terminal and run in the background as system daemons.
54fe982013-11-01Per Hedbor  o Debug.pp_object_usage()
cb784a2013-11-02Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  Pretty-print debug information, useful to get debug information about object counts and memory usage in pike applications. Uses the new _object_size lfun, if present in objects, to account for RAM-usage in C-objects that allocate their own memory.
54fe982013-11-01Per Hedbor 
0492422013-11-03Per Hedbor o Mysql

2ac4992011-03-09Martin Stjernholm 
75d6562013-11-15Henrik Grubbström (Grubba)  The function calculates the Levenshtein distance between two strings. The Levenshtein distance describes the minimum number of edit operations (insert, delete or substitute a character) to get from one string to the other. This can be used in approximate string matching to find matches for a short string in many longer texts, when a small number of differences is expected.
0d74632013-11-02Per Hedbor 
cb784a2013-11-02Per Hedbor o System.sync()
75d6562013-11-15Henrik Grubbström (Grubba)  Synchronizes the filesystem on systems where this is possible (currently windows and UNIX-like systems).

44ca4b2013-11-17Per Hedbor o access() Check if a file exist and can also return if it is readable and or writeable for the current process.
3033412013-11-03Per Hedbor o glob()
c8ae882013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  The glob function has been extended to accept an array of globs as the first (glob pattern) argument. In this case, if any of the given patterns match the function will return true, or, if the second argument is also an array, all entries that match any glob in the first array.
0492422013-11-03Per Hedbor 
c8ae882013-11-03Per Hedbor o Stdio.UDP():
75d6562013-11-15Henrik Grubbström (Grubba)

75d6562013-11-15Henrik Grubbström (Grubba) 
c8ae882013-11-03Per Hedbor  + send_fd and receive_fd
75d6562013-11-15Henrik Grubbström (Grubba)  These functions can be used to send and receive an open file-descriptor over another file-descriptor. The functions are only available on some systems, and they generally only work when the file the descriptors are sent over is a UNIX domain socket or a pipe.
0492422013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  + Changed internally to remove one level of indirection.
c8ae882013-11-03Per Hedbor  The Stdio.File object no longer has a _Stdio.Fd_ref in _fd. They are instead directly inheriting _Stdio.FD. _fd is still available for compatibility, but internally it is gone.
75d6562013-11-15Henrik Grubbström (Grubba)  + Fixed grantpt() on Solaris failing with EPERM.
ec0bce2014-07-21Per Hedbor o Unicode databases updated to 7.0.0 from 5.1.0

c8ae882013-11-03Per Hedbor o The Search search engine module has seen several fixes
75d6562013-11-15Henrik Grubbström (Grubba) 
c8ae882013-11-03Per Hedbor  + Added support for padded blobs. This improves performance when incrementally growing blobs. This feature is only enabled if Search.Process.Compactor says this is OK, see the documentation for more information. + Several locking optimizations, specifically, avoid locking and unlocking for every single iteration when merging and syncing blobs. + Charset conversion fixes + Fixes for queries where the same world occur multiple times ('foo and bar and foo')
0492422013-11-03Per Hedbor o pike -x benchmark

75d6562013-11-15Henrik Grubbström (Grubba) 
4e5e002013-11-03Per Hedbor  + Fixed two compares that were written as assignments (errno checks for EINTR for sockets)
3a6fd92013-10-08Per Hedbor o System.get_home + System.get_user
75d6562013-11-15Henrik Grubbström (Grubba)  (mostly) Cross-platform ways to get the user name and home directory.
3033412013-11-03Per Hedbor 
3a6fd92013-10-08Per Hedbor o System.AllocConsole, System.FreeConsole and System.AttachConsole for NT
75d6562013-11-15Henrik Grubbström (Grubba)  These are useful to create or close the console window that is shown for pike programs.
3033412013-11-03Per Hedbor 
3a6fd92013-10-08Per Hedbor o Process - forkd
3033412013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  Forkd can be used to more cheaply create new processes on UNIX like systems. This is done by first starting a sub-process that is then used to create new processes.
3033412013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba)  If your main process is large, this is significantly faster than using the normal create_process, and does not risk running out of memory for the forked (temporary) copy of the main process that is created.
3033412013-11-03Per Hedbor 
0492422013-11-03Per Hedbor o MacOSX CoreFoundation support in the backend

3a6fd92013-10-08Per Hedbor o Fixes to Process.run, Process.spawn_pike and friends.
75d6562013-11-15Henrik Grubbström (Grubba)  + Support OS/2 path conventions + Fixed multiple issues with search_path()/locate_binary() - locate_binary() is now more reliable on Windows - Now invalidates the cached path is PATH is changed - Uses locate_binary to scan the path - spawn_pike() now uses search_path() + You can now optionally have System.spawn_pike pass predefines, program and include path to the spawned pike, in addition to the module path.
74d6812013-11-03Per Hedbor 
0492422013-11-03Per Hedbor o Lots of autodoc fixes
75d6562013-11-15Henrik Grubbström (Grubba)  A lot more of the previously existing, but broken, documentation is now readable.
0492422013-11-03Per Hedbor  o predef::types
75d6562013-11-15Henrik Grubbström (Grubba)  This is equivalent to values and indices, but instead gives the types for each value. Basically only useful for objects.
c8ae882013-11-03Per Hedbor  o Builtin._get_setter
75d6562013-11-15Henrik Grubbström (Grubba)  This function returns a setter for a variable in an object. The setter, when called, will set the variable value to the passed argument.
c8ae882013-11-03Per Hedbor 
3a6fd92013-10-08Per Hedbor o Parser.XML.Tree fixes

b61e1b2014-07-25Henrik Grubbström (Grubba) o Multiple threads can now call the Backend `() function (the function that waits for events). The first thread will be the controlling thread, and all callbacks will be called in it, the other threads will wake when the controlling thread is done.
dbcab02013-11-03Per Hedbor o dtrace support (on MacOSX)
75d6562013-11-15Henrik Grubbström (Grubba)  Pike now supports dtrace events on function enter and leaving (and when stack frames are notionally popped, for functions doing tailrecursion). o sizeof() now supports ADT.struct.
ec0bce2014-07-21Per Hedbor o Standards.JSON.encode can now get the initial indentation level specified. This is rather useful for recursive calls encode in pretty print mode (common for objects with encode_json methods). o Added Pike.identify_cycle(x) Checks to see if x contains any circular structures. This can be useful while optimizing to identify reference cycles in Pike data structures, so that the need for garbage collection can be reduced. o Most math functions (log, pow, exp sin, cos etc) can now take integers as arguments in addition to a floating point number. The result will still be a float, the argument will be converted.

7e027d2014-07-21Per Hedbor o The random(), random_string() and random_seed() might be more random On computers with a hardware pseudo random generator random() can return significantly more random numbers, however, this means that random_seed is a no-op on those machines. A side-effect of this is that random_string is now actually significantly faster on at least x86 cpu:s with rdrnd. Note: If you want cryptographically random data please use Crypto.Random.random_string unless you know for sure the random data returned by the RDRND instruction is random enough.
c8ae882013-11-03Per Hedbor 
b61e1b2014-07-25Henrik Grubbström (Grubba) SSL --- o SSL now supports TLS 1.0 (SSL 3.1), TLS 1.1 and TLS 1.2. o Several identifiers have changed names: SSL.alert -> SSL.Alert SSL.connection + SSL.handshake -> SSL.{Client,Server,}Connection SSL.context -> SSL.Context SSL.packet -> SSL.Packet SSL.session -> SSL.Session SSL.sslfile -> SSL.File SSL.sslport -> SSL.Port SSL.state -> SSL.State
ec0bce2014-07-21Per Hedbor  o SSL.File: Changed client/server selection API.
b61e1b2014-07-25Henrik Grubbström (Grubba)  Client and server operation is now selected by calling either connect() (client-side) or accept() (server-side) after creating the SSL.File object.
ec0bce2014-07-21Per Hedbor 
b61e1b2014-07-25Henrik Grubbström (Grubba)  Blocking handshaking mode is selected by calling set_blocking() before either of the above.
ec0bce2014-07-21Per Hedbor 
b61e1b2014-07-25Henrik Grubbström (Grubba) o SSL.File: Redesigned I/O state machine.
3033412013-11-03Per Hedbor 
b61e1b2014-07-25Henrik Grubbström (Grubba)  This reduces the complexity and risk of bugs in the I/O handling.
75d6562013-11-15Henrik Grubbström (Grubba) 
b61e1b2014-07-25Henrik Grubbström (Grubba) o SSL support for lots of new cipher suites added: + AEADs and modes: - CCM and CCM-8 - CHACH20-POLY1305 - GCM + Certificates - ECDSA + Ciphers - AES and AES-256 - CAMELLIA and CAMELLIA-256 + Key exchange methods - DH and DHE - ECDH and ECDHE + All suites currently defined consisting of combinations of the above (and earlier existing) have been added (~190 suites in total). o TLS Extensions added: + ALPN (Application Layer Protocol Negotiation) (RFC 7301). + EC Point Formats (RFC 4492). + Elliptic Curves (RFC 4492). + Encrypt then MAC. + Fallback SCSV. + Heartbeat (RFC 6520). + Max Fragment Length (RFC 6066). + Padding. + Renegotiation info (RFC 5746). + Signature Algorithms (RFC 5246). + SNI (Server Name Indicator) for both client and server (RFC 6066). + Truncated HMAC (RFC 6066). o Improved protection against various SSL/TLS attacks: + BEAST protection (aka 1/(n-1)). Improve resilience against the BEAST client-side attack, by splitting the first data packet into two, where the first only contains a single byte of payload. + Heartbleed protection. The protocol code now probes the peer for the Heartbleed vulnerability, and aborts the connection with ALERT_insufficient_protection if so. + Lucky 13 protection. Attempts to have HMAC calculation take the same amount of time regardless of padding size. o SSL.Context: Improved cipher suite selection: + Filtering of weak cipher suites. + Suite B (RFC 6460). o SSL.Context: Support multiple concurrent certificates. This allows a server to eg have both an RSA and an ECDSA certificate. Crypto and Nettle -----------------
c8ae882013-11-03Per Hedbor  o Nettle refactored
573f8f2013-12-04Martin Nilsson  CBC cipher mode is now twice as fast.
b61e1b2014-07-25Henrik Grubbström (Grubba) o Nettle 3.0 supported.
573f8f2013-12-04Martin Nilsson 
b61e1b2014-07-25Henrik Grubbström (Grubba)  The new APIs in Nettle 3.0 are now detected and utilized.
75d6562013-11-15Henrik Grubbström (Grubba) 
b61e1b2014-07-25Henrik Grubbström (Grubba) o Crypto.GCM
0492422013-11-03Per Hedbor 
b61e1b2014-07-25Henrik Grubbström (Grubba)  GCM (Galois Counter Mode) cipher mode added.
c8ae882013-11-03Per Hedbor 
3a6fd92013-10-08Per Hedbor o Blowfish and Serpent support fixed in Nettle
7876c92013-11-01Per Hedbor 
c8ae882013-11-03Per Hedbor o Crypto.PGP
75d6562013-11-15Henrik Grubbström (Grubba)  Added support for SHA256, SHA384 and SHA512 as hash functions. Expose the used hash and key types in the out data
c8ae882013-11-03Per Hedbor 
8b327e2013-12-02Martin Nilsson o Crypto.Arctwo
5c38332013-11-03Henrik Grubbström (Grubba) 
8b327e2013-12-02Martin Nilsson  The 1-128 bit cipher Arctwo is now provided as a block cipher in
5c38332013-11-03Henrik Grubbström (Grubba)  Crypto. This cipher is only intended for compatibility with OLD third party code, and should NOT be used for new development.
8b327e2013-12-02Martin Nilsson o Crypto.Camellia
c8ae882013-11-03Per Hedbor 
8b327e2013-12-02Martin Nilsson  The 128/256 bit cipher Camellia is now available as block cipher in
b61e1b2014-07-25Henrik Grubbström (Grubba)  Crypto. * Crypto.ECC Elliptic Curve operations are now supported when compiled with Nettle 3.0 or later.
c8ae882013-11-03Per Hedbor 
75d6562013-11-15Henrik Grubbström (Grubba) o Crypto.SALSA20 and Crypto.SALSA20R12 The 128/256 bit cipher SALSA20 is now available as a stream cipher in Crypto. SALSA20R12 is SALSA20 reduced to just 12 rounds. o Crypto.SHA3_224, Crypto.SHA3_256, Crypto.SHA3_384 and Crypto.SHA3_512 The SHA-3 secure hash algorithm has been added in multiple variants.
8b327e2013-12-02Martin Nilsson o Crypto.GOST94 and RIPEMD160 The lesser used hash functions GOST R 34.11-94 (RFC 4357) and RIPEMD160 have been added. o Crypto.RSA and Crypto.DSA The key generation for RSA and DSA are now done by Nettle. This
573f8f2013-12-04Martin Nilsson  results in 90% faster key generation for RSA. Key generation for DSA is 10 times slower, but produces better quality keys.
8b327e2013-12-02Martin Nilsson  o Crypto.Hash Added support for pbkdf1 from PKCS#5v1.5 and pbkdf2 from PKCS#5v2.0.
b61e1b2014-07-25Henrik Grubbström (Grubba) o Standards.PEM + Added some support for encrypted PEM files
85029a2013-11-24Martin Nilsson o Standards.X509 X509 was moved from Tools to Standards and has been refactored and bug fixed. It is now possible to extend both validation and creation
8b327e2013-12-02Martin Nilsson  of certificates with new cipher and hash algorithms. A range of new algorithms are supported for both RSA and DSA:
85029a2013-11-24Martin Nilsson  RSA MD2 RSA MD5 RSA SHA-1 RSA SHA-2-256 RSA SHA-2-384 RSA SHA-2-512 DSA SHA-1 DSA SHA-2-224 DSA SHA-2-256
b61e1b2014-07-25Henrik Grubbström (Grubba)  Note that the API has changed compared to Tools.X509 and there is
85029a2013-11-24Martin Nilsson  now a single make_selfsigned_certificate() method for both RSA and DSA, though it takes the same arguments. In addition a hash function and serial number can be supplied. The hash function defaults to SHA-2-256.
ec0bce2014-07-21Per Hedbor  Incompatible C-level API changes -------------------------------- o New svalue layout The most obvious change is that the macros TYPEOF() and SUBTYPEOF() are now actually needed to directly access the type and subtype of an svalue, the svalues no have 'type' and 'subtype' members. There are also a few additional macros used to set both the type and subtype of an svalue at the same time: SVAL_SET_TYPE_SUBTYPE(sval,type,subtype) and SVAL_SET_TYPE_DC(sval,type) (these are only neede if you do not use the usual push_* macros) They are useful because they (usually) compiles to significantly more compact code, especially if the type and subtype are compiletime constants. The _DC variant will either leave the subtype unchanged or set it to 0, useful when you do not care about the actual subtype (which is, really, most of the time). o get_storage() returns void* There is no need for casts in non-C++ code.
c8ae882013-11-03Per Hedbor 
3521322013-11-02Per Hedbor Building and installing ----------------------- o -fvisibility=hidden is now the default
75d6562013-11-15Henrik Grubbström (Grubba) 
3521322013-11-02Per Hedbor  This means that PMOD_EXPORT is now actually needed on systems like Linux and MacOSX. It also means that the binary is slightly smaller and faster. o clang compilation fixes (bignum overflow checks, misc)
75d6562013-11-15Henrik Grubbström (Grubba) 
3521322013-11-02Per Hedbor  It is now possible to compile pike using a modern clang compiler. o Removed bundles
75d6562013-11-15Henrik Grubbström (Grubba) 
0e166f2013-11-02Martin Nilsson  Pike no longer comes with copies of some libraries, and the support for that in the makefile has been removed.
3521322013-11-02Per Hedbor  o Several OS/2 and windows compilation fixes
44ca4b2013-11-17Per Hedbor Lots of bug fixes -----------------
7876c92013-11-01Per Hedbor 
44ca4b2013-11-17Per Hedbor o Fixed symbol resolution with deep inherits and mixins
7876c92013-11-01Per Hedbor 
44ca4b2013-11-17Per Hedbor o Fixed PNG 4bpl indexed mode with alpha
7876c92013-11-01Per Hedbor 
44ca4b2013-11-17Per Hedbor o The _sprintf LFUN now works with %F
7876c92013-11-01Per Hedbor 
ec0bce2014-07-21Per Hedbor o foreach( arr[-two()..], string x), where two() returns 2 will no longer iterate over the first element in the array three times or crash. o Fixed a typo from 2001-05-05 that caused a lot of countries to recide on the continent ',Europa' instead of "Europa" in Geography.Countries. Obviously the continent is not that often checked. o Fixed interresting bug in the constant number parsing for octal numbers in escapes. For whatever reason 8:s were accepted for every location except the first in octal numbers, so 078 was considered an alias for 0100. This could cause issues at times, and will result in string parsing being somewhat different: | Pike v7.8 release 700 running Hilfe v3.5 (Incremental Pike Frontend) | > "\078"; | (1) Result: "@" | Pike v8.0 release 3 running Hilfe v3.5 (Incremental Pike Frontend) | > "\078"; | (1) Result: "\a8"
44ca4b2013-11-17Per Hedbor o A lot more, see the (more or less) full changelog for more info:
