3a6fd92013-10-08Per Hedbor Pike 8: Changes since Pike 7.8 (scratch area for future release notes)
2ac4992011-03-09Martin Stjernholm ----------------------------------------------------------------------
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.
75d6562013-11-15Henrik 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 
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 
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 new instructions (x86-64) and opcodes (pike) to it.
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 
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 
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 
75d6562013-11-15Henrik 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
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'
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.
0d74632013-11-02Per Hedbor 
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)

4e5e002013-11-03Per Hedbor o Bz2.File added
75d6562013-11-15Henrik Grubbström (Grubba)  It implements a Stdio.File like API, including support for the same iterator API that Stdio.File has, allowing for convenient line iterations over BZ2 compressed files. | foreach( Bz2.File("log.bz2")->line_iterator(); int n; string line )
89a3182013-11-02Martin Nilsson 
0492422013-11-03Per Hedbor o Image.JPEG

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 
cb784a2013-11-02Per Hedbor o SDL.Music added to SDL.

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.

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

3a6fd92013-10-08Per Hedbor o String.levenshtein_distance()
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).

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)

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.
3033412013-11-03Per Hedbor o Unicode databases updated to 6.3.0 from 5.1.0

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)  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

74d6812013-11-03Per Hedbor  o Better IPv6 support.
75d6562013-11-15Henrik Grubbström (Grubba)  This includes detection of IPV6 mapped IPV4 addresses (::FFFF:i.p.v.4) and full support for IPv6 in the UDP code.
74d6812013-11-03Per Hedbor  o Asynchronous Protocols.SNMP client
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

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 
5c38332013-11-03Henrik Grubbström (Grubba) o Crypto.ARCTWO The 1-128 bit cipher ARCTWO is now provided as a block cipher in Crypto. This cipher is only intended for compatibility with OLD third party code, and should NOT be used for new development.
c8ae882013-11-03Per Hedbor o Crypto.CAMELLIA
dbcab02013-11-03Per Hedbor  The 128/256 bit cipher CAMELLIA is now available as block cipher in
c8ae882013-11-03Per Hedbor  Crypto. In addition the following cipher suites have been added to SSL: TLS_rsa_with_camellia_128_cbc_sha TLS_dhe_dss_with_camellia_128_cbc_sha TLS_dhe_rsa_with_camellia_128_cbc_sha TLS_rsa_with_camellia_256_cbc_sha TLS_dhe_dss_with_camellia_256_cbc_sha TLS_dhe_rsa_with_camellia_256_cbc_sha
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.
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 with new cipher and hash algorithms. A range of new algorithms are supported for both RSA and DSA: 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 Note that the API has changed compared with Tools.X509 and there is 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.
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)
