pike.git/CHANGES:106:
o The type-checker has been rewritten. Mainly it is now much better at finding type errors, and most error messages are more readable. o Allow '.' to be used as an index operator in the few places it did not work before. o "Safe" index
+
Copied from a popular extension to other C-like languages. X[?ind] is equivalent to ((auto _ = X),(_ && _[ind])) while X?->ind is equivalent to ((auto _ = X),(_ && _->ind)) The main use is 'deep indexing' where some elements can be 0: | request_id?->user?->misc?->x vs
pike.git/CHANGES:129:
o Added the '?:' operator for compatibility with other C-like languages. It is identical to '||' in pike. o The && operator changed, when doing A && B, and A is false, keep A instead of returning 0. This is especially useful then A is not actually 0, but an object that evaluates to false, or UNDEFINED.
+
New preprocessor features ------------------------- o Support for the ", ##__VA_ARGS__" cpp feature.
-
+
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__) 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. o The preprocessor can now be run with a cpp prefix feature.
-
+
This is currently used by the precompiler to avoid two levels of preprocessing, one using "#cmod_" as the prefix and the other "#". o Dynamic macros
-
+
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()",
pike.git/CHANGES:203:
| float value() { | return floating_average_diff(requests); | } | } Optimizations ------------- o New significantly faster block allocator
+
The free in the old one was O(n^2), which means that as an example 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 thing (binarytrees) from O(n^2) to O(n), and as such is more than a simple percentual speedup in some cases, but it always improves the performance some since the base speed is also faster. o Power-of-two hashtables are now used for most hashtables
pike.git/CHANGES:255:
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. The fairly common case where you are doing lower_case or upper_case on an already lower or uppercase strings is now significantly faster. o Several other optimizations to execution speed has been done
+
+ object indexing (cache, generic speedups)
-
+
+ lower_apply, changes to apply in general Taken together these individually small optimizations speeds up at least pike -x benchmark more than 5%.
-
+
+ A lot of opcodes implemented in machine-code for x86-64 This speed up the loop benchmarks close to a factor of 3. But then again, most real code is nothing like that benchmark.
-
+
+ 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 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 x86-64 opcodes, there is no need to check the types, do a real pop_stack etc. o Faster hash-function for strings
-
+
+ Also siphash24 was added and is used in case the string hash table becomes inefficient
-
+
Deprecated features and modules ------------------------------- o Tools.PEM and Tools.X409 deprecated
-
+
Use the corresponding modules in Standards. o The built in sandbox is now deprecated
-
+
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.
-
+
Removed features and modules ---------------------------- o Removed facets
-
+
The optional (and not enabled by default) support for facet classes has been removed, since it was only partially done and not really used. o It is no longer possible to compile pike without libgmp.
-
+
Bignums are now a required language feature o The old low-level 'files' module has been renamed to _Stdio o 'GTK' is now GTK2, not GTK1 unless the system has no GTK2 support. o Locale.Charset
-
+
The charset module is now available on the top level as 'Charset'
-
+
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.
+
+
New modules ----------- o Pike.Watchdog
-
+
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. To use it simply keep an instance of the watchdog around in your application: | Pike.Watchdog x = Pike.Watchdog( 5 ); // max 5s blocking 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. o Crypto.Password
-
+
A module that can be used to verify and create passwd/ldap style password hashes. It tries to support most common password hashing schemes. o Debug.Profiling
-
+
Tools useful for collecting and format for output the profiling information generated when pike is compiled --with-profiling. o NetUtils
-
+
This module contains a lot of functions useful for the storage and processing of network addresses, it supports IPv4 and IPv6. o Added ADT.CritBit module
-
+
Mapping-like key-sorted data structures for string, int and float-keys (ADT.CritBit.Tree, ADT.CritBit.IntTree, ADT.CritBit.FloatTree). Implemented in C. o Standards.BSON
-
+
A new module for working with BSON serialized data. See http://bsonspec.org/ o Geography.GeoIP
-
+
Does geolocation of IPv4-numbers using databases from maxmind.com or software77.net o Protocols.WebSocket
-
+
An implementation of the WebSocket (RFC 6455) standard, both server and client o Image.WebP
-
+
Encoder and decoder for the WEBP image format. More information about the format can be found on https://developers.google.com/speed/webp/ o Serializer
-
+
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. o Filesystem.Monitor and the low level System.Inotify + System.FSEvents
-
+
Basic filesystem monitoring. 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. o Mysql.SqlTable
-
+
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. Among other things, this class handles some convenient conversions between SQL and pike data types o Parser.CSV
-
+
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. o ZXID
-
+
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. o Git
-
+
A module for interacting with the Git distributed version control system. o Val
-
+
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. o __builtin
-
+
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).
-
+
Extensions and new functions ---------------------------- o Bz2.File added
-
+
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 ) o Image.JPEG
-
+
+ decode now supports basic CMYK/YCCK support
-
+
+ exif_decode is a new function that will rotate the image according to exif information o String.Buffer
-
+
String.Buffer can now add the storage from a different String.Buffer object with the add() method. 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. o SDL.Music added to SDL.
-
+
Allows the playback of audio/music files. Requires the SDL_mixed library. o System.TM
-
+
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. o decode_value now throws the error object Error.DecodeError.
-
+
Useful to catch format errors in the decode string. o Process.daemon
-
+
The daemon() function is for programs wishing to detach themselves from the controlling terminal and run in the background as system daemons. o Debug.pp_object_usage()
-
+
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. o Mysql
-
+
+ Added support more modern client libraries (incl. MariaDB)
-
+
+ Mysql.mysql now has methods to query the id or SQLSTATE of the last error. o Protocols.DNS
-
+
+ Prevent endless loops in maliciously crafted domain names.
-
+
+ Add QTYPE T_ANY to DNS enum EntryType in DNS.pmod.
-
+
+ Handle truncated labels
-
+
+ TCP client and server support o Thread no longer inherits Thread.Thread (aka thread_create) o Thread.Farm now might work o Cmod precompiler.
-
+
+ inherit "identifier" -- inherit the program returned by calling master()->resolve() on the specified identifier. Useful to inherit code written in pike. o String.levenshtein_distance()
-
+
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. o System.sync()
-
+
Synchronizes the filesystem on systems where this is possible (currently windows and UNIX-like systems). o System.getloadavg()
-
+
Return the current 1, 5 and 15 minute system load averages as an array. o glob()
-
+
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. o Stdio.UDP():
-
+
+ added IPv6 multicast support
-
+
+ added set_buffer o Stdio.File():
-
+
+ send_fd and receive_fd 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. + Changed internally to remove one level of indirection. 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.
-
+
+ Fixed grantpt() on Solaris failing with EPERM.
+
o Unicode databases updated to 6.3.0 from 5.1.0
-
+
This is the latest released Unicode database from unicode.org. o The Search search engine module has seen several fixes
-
+
+ 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') o pike -x benchmark
-
+
+ Output format changed
-
+
+ Also added support for JSON output.
-
+
+ The results should be more consistent.
-
+
+ Added options to allow comparison with a previous run. o New stand-alone tools added to make it possible to build documentation without the pike build tree
-
+
+ autodoc_to_html AutoDoc XML to HTML converter.
-
+
+ autodoc_to_split_html AutoDoc XML to splitted HTML converter.
-
+
+ git_export_autodoc Exports a stream of autodoc.xml suitable for git-fast-import. Used on pike-librarian. o Readline tries to set the charset to the terminal charset
-
+
This makes it possible to write non-7bit characters on a terminal if the terminal supports it. o Fixed units in pike --help=kladdkaka o Several changes has been done to the GTK2 module
-
+
+ GTK2.DrawingArea no longer crash in draw_text if you pass odd parameters.
-
+
+ draw_pixbuf can now be passed width and height -1, which makes it take the size from the passed image.
-
+
+ GDKEvent no longer crash when you extract strings from them
-
+
+ accelerators now work
-
+
+ Fixed RadioToolButton
-
+
+ signal_connect can now connect a signal in front of the list
-
+
+ Several fixes to Tree related objects
-
+
+ GTK2.SourceView added
-
+
+ GTK2.Spinner added o A few issues were fixed that were found by Coverity
-
+
+ Fixed memory leak in Math.Transform
-
+
+ Fixed two compares that were written as assignments (errno checks for EINTR for sockets) o System.get_home + System.get_user
-
+
(mostly) Cross-platform ways to get the user name and home directory. o System.AllocConsole, System.FreeConsole and System.AttachConsole for NT
-
+
These are useful to create or close the console window that is shown for pike programs. o Process - forkd
-
+
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. 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. o MacOSX CoreFoundation support in the backend
-
+
This makes it somewhat more likely that native libraries can work with pike. o Better IPv6 support.
-
+
This includes detection of IPV6 mapped IPV4 addresses (::FFFF:i.p.v.4) and full support for IPv6 in the UDP code. o Asynchronous Protocols.SNMP client o Fixes to Process.run, Process.spawn_pike and friends.
-
+
+ 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. o Lots of autodoc fixes
-
+
A lot more of the previously existing, but broken, documentation is now readable. o predef::types
-
+
This is equivalent to values and indices, but instead gives the types for each value. Basically only useful for objects. o Builtin._get_setter
-
+
This function returns a setter for a variable in an object. The setter, when called, will set the variable value to the passed argument. o Parser.XML.Tree fixes
-
+
+ Several namespace improvement and handling fixes o New charsets
-
+
A lot of ISO-IR charsets added: 9-1, 9-2, 31, 232, 234, 231 (aka ANSI/NISO Z39.46, aka ANSEL) 230 (aka TDS 565) 225 (SR 14111:1998), 197/209 (sami) 208 (IS 434:1997) 207 (IS 433:1996), 204,205 and 206 (aka 8859-1, 8859-4 and 8859-13 with euro) 201, 200, 138 (ECMA-121) 198 (ISO 8859-8:1999) 182, 181, 189 (TCVN 5712:1993, aka VSCII) 167, 166 (aka TIS 620-2533 (1990)), 164, 160, 151 (NC 99-10:81), 68 (APL), 59 (CODAR-U), 202 (KPS 9566-97). Fixed CSA_Z242.4 o Several fixes to Protocols.HTTP
-
+
+ Improved Protocols.HTTP.Query.PseudoFile (significantly better Stdio.Stream simulation)
-
+
+ Do not use hard coded Linux errno:s
-
+
+ Case insensitive handling of header overrides in do_method
-
+
+ Fixed broken check for URL passwords when querying
-
+
+ Add more descriptive HTTP responses along with a mostly complete list of codes
-
+
+ Handle non-standards compliant relative redirects
-
+
+ Cleaner handling of async DNS failures
-
+
+ Handle chunked transfer encoding correctly when doing async queries
-
+
+ Fixes for the proxy client support
-
+
+ Several keep-alive handling fixes
-
+
+ Server: - More forgiving MIME parsing for MSIE - Fixed range header handling - Fixed parsing of broken multipart/form-data data - Added optional error_callback to attach_fd - The response processor (response_and_finish) now treats the reply mapping as read-only. - Support if-none-match (etag:s) - Ignore errors in close when destroying the object o dtrace support (on MacOSX)
-
+
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.
+
+
Crypto and SSL -------------- o SNI client extension support for SSL (Server Name Indicator) o Standards.PEM
-
+
+ Added some support for encrypted PEM files o Nettle refactored o AES support added to the SSL module
-
+
This adds support for the following cipher suites: TLS_rsa_with_aes_128_cbc_sha TLS_dhe_dss_with_aes_128_cbc_sha TLS_dhe_rsa_with_aes_128_cbc_sha TLS_rsa_with_aes_256_cbc_sha TLS_dhe_dss_with_aes_256_cbc_sha TLS_dhe_rsa_with_aes_256_cbc_sha o SSL now supports TLS 1.0 (SSL 3.1) and TLS 1.1
pike.git/CHANGES:740:
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
+
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.
+
+
Building and installing ----------------------- o -fvisibility=hidden is now the default
-
+
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)
-
+
It is now possible to compile pike using a modern clang compiler. o Removed bundles
-
+
Pike no longer comes with copies of some libraries, and the support for that in the makefile has been removed. o Several OS/2 and windows compilation fixes - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - > snip - > snip - > snip - > snip - > snip - > snip - > snip - > snip - > s - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
