pike.git/CHANGES:35:   o ** operator added. It's exponentiation and works with most    combination of numerical types (int,float,Gmp.mpq,Gmp.mpf,Gmp.mpz)       `** and ``** operator overloading functions added.       This introduces one incompatible change: Previously the "pow"    function called a "_pow" function in the first argument if it was an    object. It has now been changed to also use `** (or, rather, pow()    is now implemented using predef::`**()).    + o New syntax for literal strings. +  + o #pragma disassemble +  +  The byte code output is now interleaved with the generated machine code +  on selected architectures. +  + o Complain about redundant backslash escapes. +  + o '__weak__' keyword added. +  + o Function local function declarations are now statements +  (and not expressions). This means that there is no longer +  any need to terminate them with a semicolon. +  + o Complain about shadowed variant functions. +  + o Machine code support for more architectures. +  +  There's now machine code support for arm32 and arm64. +  + o Fixed multiple integer over- and underflow bugs. +  +  + Incompatible changes + -------------------- +  + o Gz.crc32 and Nettle.crc32c now only return positive results. +  + o glob() has changed. +  +  The main incompatibilities are that [ and \ are now special +  characters in the pattern, and if you check the return value against +  1 instead of checking if it's true, and use an array as the first +  argument you will have to change your code. +  +  This is in order to extend the glob function to cover what +  'standard' glob functions do: +  +  glob() now accepts quotes (\* to match a single *, as an example) +  and handles ranges ([abc] for a, b or c, [a-z0-9] for a single +  character between a and z or 0-9 +  +  You can also negate a range using ^ or ! ([^a-zA-Z] as an example). +  +  When the first argument (the pattern) to glob is an array, glob now +  returns which pattern in the array matched. +  + o hash() has been changed to use siphash. The old hash function is +  available under the name hash_8_0(). Note that this is not a +  cryptographic hash function. +  + o Stdio.UDP()->send() no longer throws errors on EMSGSIZE and EWOULDBLOCK. +  + o If a thread exits with by throwing, the thrown value is propagated to wait(). +  + o String.trim_all_whites() renamed String.trim(). +  +  + New modules + ----------- +  + o ADT.Scheduler + o ADT.TreeScheduler + o Apple.Keychain + o __builtin.Sql + o CompilerEnvironment()->lock() + o Crypto.ECC.Curve.Point + o Filesystem.Zip + o Function.bind() + o Standards.HPack (RFC 7541) + o Stdio.FakePipe + o Parser.Markdown +  + o Concurrent.Future and Concurrent.Promise +  +  These are used to simplify handling of asynchronous results. +  + o Crypto.Checksum +  +  This module collect non-cryptographic checksums. Support for crc32, +  adler32 and Castagnoli CRC (CRC32C). +  +  NB: In the future these may be amended to support the Crypto.Hash API. +  + o Protocols.EngineIO & Protocols.SocketIO + o Protocols.HTTP2 + o Bittorrent.DHT + o Standards.MsgPack + o Web.Auth & Web.Api +  +  + New features + ------------ +  + o predef::gc() +  +  gc() called with a weak mapping as argument now removes weak references +  that are only held by that mapping. +  + o predef::sprintf() +  +  sprintf() now replaces %m with strerror(errno()). +  + o ADT.Heap +  +  - An indirection object ADT.Heap.Element has been added to make it +  possible to optimize several heap operations. +  +  - Added low_pop(). +  + o Crypto & Nettle +  +  - Added Curve25519 and EdDSA25519. +  + o Filesystem.Monitor +  +  The filesystem monitoring system now uses accelleration via +  Inotify et al. +  + o Gmp +  +  - mpf is now implemented using gmpf if the library is available. +  +  - Improved support for GMP 5.0 and later. +  + o GTK2 +  +  Multiple runtime fixes. +  + o JOSE (JSON Object Signing and Encryption) +  +  Some low-level API support has been added to the Crypto and Web +  modules to support parts of RFC 7515 - 7520. +  + o MasterObject +  +  - Protect against the same file being compiled concurrently +  in multiple threads. +  +  - cast_to_program() and cast_to_object() should now be thread safe. +  + o Parser.Pike +  +  Support new language features. +  + o Protocols.WebSocket +  +  Multiple API changes. +    o Random rewrite       The random functions have been rewritten to ensure security by    default. random_string() and random() now get their data directly    from the operating system random generator, i.e. /dev/urandom on    most unixen. This is about half the speed compared with the    random_string function in Pike 8.0, but is now as secure as the    system random generator.       For consumers of random data that have additional requirements,
pike.git/CHANGES:110:    All code in Pike that uses random now uses the current random    functions (though in some cases fixed at object creation). This    allows for repeatable results if the random functions are replaced    with a deterministic random generator, such as    Random.Deterministic. Example:       Random.Deterministic rnd = Random.Deterministic( seed );    add_constant( "random_string", rnd->random_string );    add_constant( "random", rnd->random );    - o JOSE (JSON Object Signing and Encryption) + o Sql    -  Some low-level API support has been added to the Crypto and Web -  modules to support parts of RFC 7515 - 7520. +  - Most Sql C-modules converted to cmod.    -  +  - Added next_result().    - Incompatible changes - -------------------- +  - ODBC & tds: Support more datatypes.    - o Gz.crc32 and Nettle.crc32c now only return positive results. +  - ODBC: Support big_typed_query().    - o glob() has changed. +  - pgsql: Lots of changes and fixes.    -  The main incompatibilities are that [ and \ are now special -  characters in the pattern, and if you check the return value against -  1 instead of checking if it's true, and use an array as the first -  argument you will have to change your code. + o SSL    -  This is in order to extend the glob function to cover what -  'standard' glob functions do: +  - Support session tickets.    -  glob() now accepts quotes (\* to match a single *, as an example) -  and handles ranges ([abc] for a, b or c, [a-z0-9] for a single -  character between a and z or 0-9 +  - Support Negotiated FF-DHE.    -  You can also negate a range using ^ or ! ([^a-zA-Z] as an example). +  - Support client certificates.    -  When the first argument (the pattern) to glob is an array, glob now -  returns which pattern in the array matched. +  - Support ALPN.    - o hash() has been changed to use siphash. The old hash function is -  available under the name hash_8_0(). Note that this is not a -  cryptographic hash function. +  - Prefer AEAD suites to CBC suites.    - o Stdio.UDP()->send() no longer throws errors on EMSGSIZE and EWOULDBLOCK. +  - SSL.File supports set_buffer_mode().    -  + o Standards.PKCS    -  +  Support PKCS#8 private keys. +  + o String.Buffer & Stdio.Buffer +  +  Added _search(). +  + o The self testing framework now supports *.test-files. +  + o Unicode 8.0.0. +  +    Deprecated symbols and modules   ------------------------------      o Sql.mysql_result and Sql.mysqls_result have been deprecated.    Use Sql.Result instead.    -  + o call_function() has been deprecated. Use `()() instead.      Removed features and modules   ----------------------------      o Compatibility for Pike versions before 7.8 is no longer available.      o GTK1 library is deprecated, so glue code is removed.       - New modules - ----------- -  - o ADT.Scheduler - o ADT.TreeScheduler - o Filesystem.Zip - o Stdio.FakePipe - o Parser.Markdown -  - o Concurrent.Future and Concurrent.Promise -  -  These are used to simplify handling of asynchronous results. -  - o Crypto.Checksum -  -  This module collect non-cryptographic checksums. Support for crc32, -  adler32 and Castagnoli CRC (CRC32C). -  -  NB: In the future these may be amended to support the Crypto.Hash API. -  - o Protocols.HTTP2 - o Bittorrent.DHT - o MsgPack -  -  - New features - ------------ -  - o Gmp.mpf is now implemented using gmpf if the library is available. -  - o The SSL module now supports session tickets. -  -  +    C-level API changes   -------------------      o The contract for functions is now changed so that a function is no    longer required to clean the stack. The topmost value of the stack    will be regarded as the return value and the rest of the items on    the stack, compared to before the function arguments were pushed,    will be popped and discarded. Efuns still have to clean their stack    as previously.      o Removed add_function, pike_add_function, pike_add_function2,    simple_add_variable, map_variable and MAP_VARIABLE. This removes the    remaining few API:s where text types were used. Use ADD_FUNCTION and    PIKE_MAP_VARIABLE instead.      o Removed the functions my_rand and my_srand. Use the random functions    on the stack for _random lfuns, the push_random_string or look up    the random function from get_builtin_constants(). For deterministic    pseudo random, create a private Random.Deterministic object.    -  + o The preprocessor has been converted into a cmod, and been modified +  to use more standard Pike datatypes.    -  + o The preprocessor-specific hashtable implementation has been removed. +  + o The gdb_backtraces() function is now available also --without-debug. +  + o There's now support to block mapping hashtables from being shrunk +  on map_delete(). +  +  + Documentation + ------------- +  + o RFC references added. +  + o Character encoding issues fixed. +  + o Added @enum/@endenum markup. +  + o Support undocumented enums with documented constants. +  +    Building and installing   -----------------------      o GMP 4.1 or later is now required.      o C99 assumed       The configure tests will not check for functions defined in C99    anymore and C99 compiler support is assumed.
