Version 0.47 Alpha Build 47 (2007-01-09) tag: build47

The compiler
==============================
syntax:
-------
- Added support for variable number of parameters functions.
- reimplemented xbase++ multi-value macro support.
- Added support for WITH OBJECT.
- Changed HB_INLINE() syntax.
- Added support for macro compiled messages.
- Added support for passing array items and object variables by reference.
internals:
----------
- Preprocessor, compiler and macrocompiler code are fully MT safe.
- New lexer which translate preprocessor tokens to grammar parser
  terminal symbols - FLEX is not longer used by Harbour.
- Added prebuild grammar parser source code to CVS - BISON is no
  longer needed to build Harbour from source code - only developers
  which want to change Harbour grammar rules need BISON.
- Cleaned grammar rules with many small fixes
- Added PCODE version information to compiled files - it's checked at
  runtime by HVM to detect problems when files with old unsupported
  PCODE are linked with current HVM.
- Fixes in memvar core code (memory leaks, GPF, Clipper compatibility, etc.)
- Added POINTER items which inspected by GC.
- Added SYMBOL items with support for :exec() and :name() messages.
- Changed function references to use SYMBOL item instead of POINTER item.
- Added support for loading and unloading dynamic libraries with PCODE
  and HRB files.
- Many new different optimizations.
preprocessor:
-------------
- New written from scratch preprocessor code.
- Added std.ch file with standard preprocessor definitions.

The runtime modules
=============================
- Modifications to make HVM code reentrant safe.
- Class code extensively changed with many extensions like nonvirtual
  methods and members, scopes, friend classes and functions,
  destructors, etc.
- Added support for PROCFILE()
- Profiler code disabled in default build.
GT:
---
- Added GTGUI.
- Added support for: REQUEST HB_GT_<name>_DEFAULT

RDD
=============================
- New USRRDD library. It allows to create new RDD from scratch
  or by inheriting from any other RDDs (except USRRDDs) and
  overloading any of their methods at PRG level.
- Added missing undocumented Clipper RDD functions.

General
=============================
- New non GNU make files with common dependencies list.
- Many speed improvements and fixes.

----------------------------------------------------------------------
Version 0.46 Alpha Build 46 (2006-05-29) tag: build46

The compiler
=============================
syntax:
-------
- Added support for DATE type constants in the format 0dYYYYMMDD
  (FLEX version only).
- Added support for SWITCH command (see tests/switch.prg)
  (FLEX version only).
- Added support for FOR EACH loop (see tests/foreach.prg)
  (FLEX version only).
- Added new compiler switch -gc3 to generate real C code output
  (instead of PCODE array called by a C wrapper).
- Added new command line switch -r=<max_recursive_preprocessor_passes>
- Added -undef: compiler switch (borrowed from xHarbour).
- Added support for @filelst[.clp] - partially borrowed from xHarbour.
  It's not exactly the same as in Clipper because Clipper creates one
  final file when [x]Harbour series of files.
- Emit warning and error messages to stderr instead of stdout on *nix
  platforms.
- Added warnings in cases of duplicated loop variables.
- Fixed compilation of included files in cases when the file ends
  with ';' (with no LF or CR).
internals:
----------
- Fixed bug in divide by 0 substitution.
- Fixed bug in ASC() optimization (when character code > 127)
- Fixed path delimiters in included file names.
- Removed strong typing in the compiler. Reactivate it by compiling
  with -DHB_COMP_STRONG_TYPES.
- Fixed to release the memory if macro compiled code contains a
  variable or a function reference.
- Rewritten jump optimization.
- Added optimization for: IF .T.
                          IF .F.
                          WHILE .T.
                          WHILE .F.
- Added dead code eliminator. It works only when Jump Optimization is
  not disabled. As a result, we have smaller and faster PCODE.
- Do not strip redundant line information when compiled for debug (-b).
- Fixed many more memory leaks in the compiler. Now, the Harbour code
  compiles itself with no memory leaks.
- Added optimalization of '+=' '-=' '*=' '/=' operators using new
  PCODS: HB_[PLUS|MINUS|MULT|DIV]EQ
         HB_[PLUS|MINUS|MULT|DIV]EQPOP
- Added more optimization for localvar+=integer using
  HB_P_LOCALNEARADDINT pcode (borrowed from xHarbour).
- Enabled FM statistic by default when compiled without
  -DHB_FM_STATISTICS_OFF.
- Added new errors (memory corruption and memory overflow) for
  compiler level FM statistic.
- Fixed double value presented in verbose genc mode for
  HB_P_PUSHDOUBLE.
- Fixed stripping non identifier characters from symbol table name.
- Added escaping of '?' character in generated strings to avoid
  possible conflicts with trigraph sequences which are part of ANSI C
  standard.
- Force .0 at the end of double numbers to avoid possible range
  conflicts in generated .c files.
- Upper the default .prg function name created from .prg file name
  when compiled without -n switch.
- Fixed registering of startup procedure name.
- Changed code generated for double values to avoid limitation in some
  C compilers like MSC and possible differ conversion inside C RTL
  then the one which uses Harbour RTL.
preprocessor:
-------------
- Fixed to release memory allocated with the preprocessor.
- Fixed bug in processing the list of optional repeatable code.
- Fixed handling of optional clauses in command/translate.
- Fixed <-x-> match marker.
- Fixed compilation of \[ and \] in command/translate.
- Fixed to preserve spaces the same way (almost) as Clipper.
- Fixed translation of nested command/translate.
- Fixed translation of TEXT/ENDTEXT to be more Clipper compatible.
- Added new hidden preprocessor directive
  __text|ParseBlockCode|EndBlockCode|StartBlockCode
- Modified TEXT/ENDTEXT to use '#pragma __text'.
- Added #pragma __stream and #pragma __cstream (see doc/pragma.txt)

The runtime modules
=============================
API
---
- Separated internal and external API. Now the definitions for
  internal HVM structures and functions are excluded by default they
  could be enabled if user include hbvmopt.h before other header
  files. Such operation should be done ONLY by core code! If 3rd party
  developers use something like that then it's for their own risk and
  such code may stop to work with next Harbour versions. Without
  hbvmopt.h the internal structures like HB_ITEM, HB_DYNS, ... are
  mapped to 'void' so there is no way to access their members so we
  can modify them in the future without afford for 3-rd party code.
- Remove default API and stack macros. Now API/stack macros can be
  enabled by including hb_vmopt.h file. This file should be included
  ONLY by core code because binary object/libraries generated after
  can work only with EXACTLY the same HVM compiled the same C
  alignment switches. 3-rd party code should include hbvmpub.h only.
- Added support to passing function references as HB_IT_SYMBOL.
- hb_itemType() return "S" for HB_IT_SYMBOL.
- Message symbols are not function symbols, cleaned the HB_FS_MESSAGE
  usage and fix the problem with registering static function in global
  symbol table.
- Added HB_TYPE to as HB_ITEM type marker (UINT32 currently).
- Cleaned some ~HB_IT_BYREF which has no effect in current VM.
- Added new functions: hb_extIsObject(), hb_codeblockId(),
  hb_idleSleep(), hb_fsGetOsHandle(), hb_dynsymFindSymbol(),
  hb_dynsymGetSymbol(), hb_dynsymSymbol(), hb_dynsymName(),
  hb_dynsymMemvarHandle(), hb_dynsymAreaHandle(),
  hb_dynsymSetAreaHandle().
- Changed definition of HB_SYMB structure.
- Cleaned some HB_EXTERN_C declaration.
- Changed hb_arrayClone() declaration to:
  PHB_ITEM hb_arrayClone( PHB_ITEM pArray )
- Changed hb_arrayFromParams() declaration to:
  PHB_ITEM hb_arrayFromParams( int iLevel )
  The previous version needed a pointer to stack relocatable area so
  any stack resizing could cause GPF.
- Allow hb_param() to return parameters accessed by HB_IT_BYREF.
- Cleaned the code which created HB_ITEMs on C stack.
- Changed main VM loop to eliminate one comparision done on each loop.
  Now HB_P_ENDBLOCK and HB_P_ENDPROC pcodes set HB_ENDPROC_REQUESTED
  and the main loop can be exited only from one place. It gives some
  small but noticeable speed improvement.
- Possible problem fixed in __CLSADDMSG() where message parameter was
  required to be uppercase when overloading operators .NOT. .AND. .OR.
- Fixed GPF when unshareing string item buffer with embedded 0 by
  using hb_itemUnShare().
- Make HB_SET_TYPEAHEAD Clipper compatible.
- Set DOSERROR() to oError:OSCODE when RT error is generated.
- Fixed some small incompatibilities with Clipper in number to string
  conversions.
- Added HB_STR_DATE_BASE for conversion to string, Clipper
  compatibility though we are not 100% Clipper compatible in STOD()
  because we will have to reduce functionality (supported date range)
  to reach it. In Clipper STOD(DTOS()) is not revertible, it is
  revertible in [x]Harbour for the whole supported in string
  conversion range: 0000/01/01 : 9999/01/01.
- Fixed possible GPF in CTOD when badly formated date is given.
- Optimized hb_dateEncode().
- Fixed RT error number in hb_vmAddInt() for negative values to be
  Clipper compatible.
- Optimized __CLSADDMSG() to call hb_parc() only once instead of 25
  times for most cases.
- Synced file IO with xHarbour, it fixed some problems, added some
  missing functionality and long (64bit) file support for Windows.
- hb_DiskSpace() changed to not give a runtime error in case of any
  error, but set the FError() value instead.
- Added C -> OS file error translations - not perfect but better then
  the used hacks (borrowed from xHarbour).
- Use hb_fileNameConv() instead of hb_filecase(), hb_fileNameConv()
  is the only one function to make file name conversions dependent on
  some SETs.
- HB_MATHERRMODE() input validation logic moved to the lower level
  function. This is a step to make this a simple Set().
- Added STRPEEK and STRPOKE FS functions covered by HB_COMPAT_FLAGSHIP
  macro.
- Added hb_fsSetDevMode() Unix branch added.
- hb_secondsCPU() move inside FlagShip guard instead of HB_EXTENSION.
- Fixed invalid handle error in Windows when file() fails (borrowed
  from xHarbour).
- SetUnhandledExceptionFilter() is called if HB_INCLUDE_WINEXCHANDLER
  define is used.
- UnhandledExceptionFilter renamed as hb_UnhandledExceptionFilter, and
  WINBASEAPI removed.
- Added new functions HBDLLENTRY1() and HBDLLENTRY2(). These function
  allow to call a Harbour (self contained) DLL and provide it one or
  two Harbour items as parameters.
- Fixed GPF in HB_LIBDO called with wrong parameter.
- Fixed optimization of 'EVAL' in macro compiler.
GT:
---
- New GTAPI.
- Multi GT support with an option to link many GT drivers in a
  single binary and switch between GTs at application startup based
  on its environment.
- Added GTI_* defintions for hb_gtInfo() function. This function
  works in similar way to dbInfo() in RDD.
- New driver GTCRS based on xHarbour and Flagship curses code.
- New driver GTWVT for Win32 using GUI window instead of console.
- New driver GTXWC for XWindow Console.
- New driver GTALLEG for Allegro cross platform graphic libraries.
- Respect pure REQUEST HB_GT_NUL as user GT choice if only GTNUL
  is linked.
- Fixed displaying of boxes under the xterm, use @ TO instead of @ BOX.
Multilangual:
-------------
- Cleaned startup initialization code for lang and codepages.
  at least one lang module defined at startup.
- Codepage: Updated UNICODE values for characters in range 1-31 to
  keep DOS compatibility.
- Codepage: Renamed files (cdp*.c -> cd*.c).
- Codepage: Added UTF8 related functions: hb_cdpUTF8StringLength(),
  hb_cdpStringInUTF8Length(), hb_cdpUTF8ToStrn().
- Moved EN lang definitions to core lang code so we always have
- HU sorting order fixed to be more compatible with Clipper.
- Added BG language support.

RDD
=============================
- DBT, FPT, SMT memos are fully support and automatically detected in
  USE command. For newly created tables the memo type can be set with
  rddInfo(RDDI_MEMOTYPE,<DB_MEMO_DBT|DB_MEMO_FPT|DB_MEMO_SMT> [,<cRdd>])
  It's possible to use any combinations of memo and index files.
- Added RDDINFO() to set global RDD parameters. See dbinfo.ch for
  possible actions.
- Rewritten DBFNTX, now it supports in practice all CDX features with
  multi tags and many others. With RDDINFO() some important new
  features in DBFNTX can be enabled like increased maximum NTX file
  size up to 4TB, support structural/autoopen indexes, bounding record
  number with index key (like in CDX format what resaolves the
  performance problem with indexes which have a lot of non unique
  keys, etc.)
- User setable locking DBF mode.
- Added SIXCDX which is modified version of DBFCDX without trailing
  spaces compresion for SIX3 compatibility.
- Added ordKeyRelPos([nNewPos])->nOldPos which works with all RDDs
  and returns relative (from 0.0 to 1.0) position in index file but
  much faster then ordKeyPos()/ordKeyCount() combination. It works
  like AdsGetRelKeyPos()/AdsSetRelKeyPos() and the results for CDX are
  the same. For NTX ADS implementation is broken, just simply Extended
  System uses the same algorithm as for CDX what is wrong.
- Fixed ordKeyPos() for records out of scope.
- Implemented RDD level transforms (COPY TO/APPEND FROM).
- Long file support for all native RDDs. Now the maximum file size
  is reduced only by its structure if OS/file system supports 64bit
  file IO, f.e. for DBF it's 2^32 records. For memos it's:
  2^32 * MemoBlockSize, etc.
- Synhronize RDD code with xHarbour.
- New HSX RDD.
- New HBSIX RDD.
- Fixed possible GPF when "/an/existing/path/" was used as file name.
- Enable 'Y' (currency) fields, translated to HB_IT_DOUBLE.
- Fixed some wrong behavior in SORT parameters setting in __dbArrange()
- Removed hack with COPY TO when lastrec() == 1.
- Fixed GPF in DBF2TEXT when work are is not in use.
- __dbDelim() generate 2001 RT error when work area is not in USED()
  before export file is created.
- Added DBI_SCOPEDRELATION action. It alow to test if given relation
  on current work area sets scope on child index.
- Set Operation in error object to field name in field{put,get}
  methods.
- Added DBI_LOCKOFFSET.
- Added support for NULL value set in memo fields by ACCESS.
- Added all Clipper 5.3 BLOB*() functions support.
- Added new RDD DBFBLOB compatible with Clipper 5.3 DBFBLOB. It
  operates on memo files only (.dbv) without tables (.dbf).
- Do not report error when empty structure table is passed to
  DBCREATE().
- Added support for NIL value in SIX3 FPT files.
- Changed definition of SUPERTABLE for optional dynamic overloading.
- Added default SYSNAME method.
- Fixed possible memory leak when APPEND failed in TRANSREC method.

Contrib
=============================
- ADS: Added ADSCDX, ADSNTX and ADT RDDs. ADS RDD should not be longer
  used, it's only for backward compatibility.
- ADS: Call AdsFlushFileBuffers() only when _SET_HARDCOMMIT is set.
- ADS: Added possibility to save memo fields > 64K.
- ADS: Added support for relations in ADS* RDDs which are not
  supported directly by ADS or are for other non ADS* tables.
- ADS: Synced base RDD with xHarbour.
- Added conversion from tiny int MySQL type into numeric DBF.
- Added MYSQL_DECIMAL_TYPE for MySQL versions 5.0 and above.
- libct: Added CT3 like Window System, it's a GT driver which inherits
  from the existing one and adds CTW functionality.
- libct: Updated for GTAPI modifications.
- libnf: Use hb_fs*() API functions instead of calling DOS interrupts.
  Now NF dir functions works on all platforms.

Utilities
=============================
- HbExtern: Heavily modified to produce more accurate output.

General
=============================
- Fixed for popper compilation with GNU C++ and OpenWatcom on Linux.
- Added support for cross compilation (Windows binaries at Linux) with
  MinGW (borrowed from xHarbour).
- Added functions for machine independent double and long long
  conversions.

- Improved memory handling.
- Removed hack for GCC and old Bison versions
- Modified creation of symbols table:
  Symbol of function name never share a symbol of variable
  Symbol for INIT/EXIT procedure has now '$' suffix - this means that
  such procedures cannot be called from user code (Clipper compatible)
- Harbour now Run on 64 bits !
- Some small optimizations in harbour/source/vm/itemapi.c

The runtime modules
-------------------
- Enabled creation of classes from C level using functions:

- Cleaned all endian dependend code found - now Harbour can be compiled
  on LITLE and BIG endian machines - for some other like PDP ENDIAN it's
  enough to define proper macros in hbdefs.h
- Added macros for to get/put values in chosen byte order:
         HB_GET_LE_[U]INT{16,24,32,64}( pPtr )
         HB_GET_BE_[U]INT{16,24,32,64}( pPtr )
         HB_PUT_LE_[U]INT{16,24,32,64}( pPtr, nVal )
         HB_PUT_BE_[U]INT{16,24,32,64}( pPtr, nVal )
- Added macro HB_CAST_BYTE_NUMBERS_OFF which disables casting in
  HB_{GET|PUT}_{LE|BE}_* macros - it's necessary for some platforms like
  ALPHA DEC.
- Many macros added for easier manipulation of different APIs and platforms.
- Clean the code (no more warning messages under Linux and GCC and DOS
  OpenWatcom) - some of them were real bugs

The compiler
------------
- Fixed support for late/early evaluation of macro exressions in a codeblock
  (Flex version). Harbour(flex) is now full Clipper compatible here.
- Fixed support for stringify match markers <""> and <()> in Flex version.
- New compiler flag -ks was added to enable support for
  strings as array of bytes. (Notice that support for strings
  as array of bytes is disabled by default both in the Harbour compiler
  and in harbour's runtime modules)
- Added a new compiler switch -kJ to disable jump optimalization and
  NOOP pcode removal (optimalization is enabled by default).
- When xbase mode is not used (-kc or -kch) then compiler doesn't
  generate the pcode for these xbase extended features.
- Added support for DO <proc> WITH @variable
- Fixed optimalization of literal strings that contain macro operator.
- Enabled support for break[].
- Fixed optimalization of far jumps (this fixes generation of pcode
  for abnormally large (DO CASE/IF/ELSEIF statements)
- Added support to OpenWatcom DOS/Win32.
- Fixed compilation of &(exp) in normal stringify
  markers (this fixes INDEX ON bug).
- Added missing support for @&macro and @M->memvar (aAdded a new
  pcode HB_MACROPUSHREF)
- Fixed generation of pcode for &(macro)->() syntax.
- Fixed #define parsing of pseudofunctions in cases where
  passed argument has the same name as declared parameter.
- Fixed parsing of nested #defines in command/translate
- Macro - Added HB_SM_ARRSTR support.
- Clipper preproceses '**' into '^' - harbour too
- Added HB_COUNTER and HB_PTRDIFF types - first for reference counters and
  second for any pointer differences and pointer to integer conversions.
- HB_EXPORT is added to ITEM API, FILE API and some other function
  definitions to make it possible to call them when they are in the dll.
- Removed all pointer/long castings (except runner.c).
- Fixed optimalization of AT,ASC,LEN,CHR functions
- Added posibility to specify the output PPO filename with -p flag
  e.g.  -pppo/myfile.ppo
- harbour.l modified to compile correctly with flex version 2.5.31.
- Fixed to compile FOR var[index]

The runtime modules
-------------------
- Enhanced Debugger.
- Added missing code to use HB_IT_POINTER just like other value's type.
  For example:
      p = GET_SOME_POINTER()
      ? VALTYPE(p)   //prints: 'P'
      ? p   //prints: 0x12345678
- The support for runtime definition of keycodes mapping was added
  (translation from terminal key sequences into INKEY() codes)
  eterm.map and linux.map are example files with keycode mapping
  HB_GT_KEYMAP() function was added (ncurses GT only)
- Added possibility to load a character mapping using HB_GT_CHARMAP()
  (ncurses GT only)
- Improved recognition of xterm compatible terminals (ncurses GT only)
- New internal command line arguments were added to control
  application at runtime:
        //FLAGS:switches
            this flag controls compatibility issues of the virtual
            machine
            Available switches:
            c - Clipper compatibility
            h - Harbour extensions (enabled by default)
            s - enable support for strings as array of bytes (disabled
                by default)
            For example:
            myapp //FLAGS:ch
            will disable support for strings as array of bytes

        //CANCEL:key
        //CANCELEX:keyex
            this flag allows change the keycode of application cancel
            request (usually Alt-C) - using normal INKEY() keycodes
            or extended keycodes (CANCELEX)
            For example:
            myapp //CANCEL:304
            will change Alt-c into Alt-b for cancelling (Alt-c is used
            to insert polish diactric letter)
- Fixed to release PUBLIC variables correctly
- Fixed bug in Directory( "c:\*.*" ) that returned 0 when hidden files
  were present.
- Alert() Fixed bug with messages longer then 60 bytes.
- TGet:display() fixed to always evaluate the get block before
  displaying like in C52.
- TBColumn - Added PreBlock and PostBlock instance variables for
  Clipper 5.3x compatibility.
- Fixed TYPE() function to return correct value when an  assigment to
  undeclared variable is checked (Clipper creates the memvar variable).
- TGet - Fixed to correctly display buffer when negative value
  and '0' was pressed in the position next to decimal point.
- TGet - Fixed support for '9999.' picture.
- TRANSFORM(1.23,"999.") correctly returns "  1." now instead of empty string.
- Fixed to correctly check for infinity on Unix STR(LOG(-1)) no longer
  core dumps.
- Fixed infinite support for WatcomC.
- Fixed to release memory in cases where invalid syntax was macro compiled.
- Added DATA CapRow and DATA CapCol values to TGET class
  (for Clipper 5.3x compatibility).
- Fixed to correctly return the procedure name where the codeblock was created.
- Greek and Serbian language codepage files added.
- fixed to use 'mkstemp' on Unix (no more GCC linker warnings)
- Fixed file find API to be compatible with CA-Cl*pper on the lower level.
- Fixes in TBColumn class

RDD
---
- Latest RDD changes synced with xHarbour.
- Fixed dbCreate() bug that closed an open dbf with same name as newly
  created dbf in a different folder.

  without runtime error. C52 compatible.
- Added scopped relations. Now OrdSetRelation() works with DBFCDX like
  it does with Clipper 5.3b.
- Changes to ADSCOPYTABLE.
- Changes to ADSCOPYTABLECONTENTS.
- Fixed rddMoveRecords() so that copied records, which are
  deleted, maintain their deleted status.

  Dumps symbol name just before it's called. This is very useful when
  debugging GPFs as it will trace all PRG-level calls up until the crash.
  Uses HB_TRACE so traces are in line with any C-level traces
- Martin and Walter added a bunch of functions to libct
- David added the Path stuff so file() and other functions can work right
- Platform support for FreeBSD 4.4, which requires installation
  of the gmake (GNU make) port (instead of using FreeBSD's make)
