Viktor Szakats 1e62fb550e 2009-01-14 16:15 UTC+0100 Viktor Szakats (harbour.01 syenar hu) 
* source/rtl/net.c
  * contrib/hbziparc/hbziparc.prg
  * contrib/hbct/files.c
    * Minor formatting.

  * source/rtl/gtxwc/gtxwc.c
    ! Fix to recent fix. An '!' was missing, Przemek pls check me.

  * source/rtl/philes.c
    + HB_PROGNAME() now returns absolute path in *NIX systems, too.
      (please test and refine)

  * source/lang/msgca.c
    ! Fixes from xhb.

  * contrib/hbziparc/hbziparc.prg
    * Minor correction ( = -> := )

  * source/rtl/gtwin/gtwin.c
    + Added HB_GTI_CODEPAGE support.
      As per MS docs, this works only when non-raster font is used
      in the console window. Notice that the accepted CP values are
      different from the GTWVT ones (GTWIN being the more "logical"
      one, since it's a newer API). Currently, Harbour doesn't try
      to hide these interface details.
    ; TODO: UNICODE and BOX char support for GTWIN mode.

  * source/rtl/tbrowse.prg
    * Using HB_DISPOUTATBOX() to draw column/header/footer separators.
    ; NOTE: This may cause problems if someone wants to use native
            CP (accented or other special CP specific) chars to draw
            these screen elements. Maybe an option should be added,
            or some sort of markings in the separator strings to
            control that.
            Pls REVIEW.

  * include/hbextern.ch
  * source/rtl/console.c
    + Added HB_DISPOUTATBOX() which is similar to HB_DISPOUTAT(),
      but marks the text drawn as HB_GT_ATTR_BOX, so these chars
      can be properly displayed as drawing chars, regardless of
      the selected codepage. Another difference is that this
      function only supports strings to be printed. Other types
      don't print anything.
    ; NOTE: Maybe this function could use a better name, pls
            review and decide.

  * source/rtl/gtwvt/gtwvt.c
  * source/rtl/gtwvt/gtwvt.h
    ! Fixed not accepting zero as a HB_GTI_CODEPAGE value.
    ! Fixed HB_GTI_CODEPAGE to change the codepage.
    + Added box char support in Unicode mode.
      For chars marked as HB_GT_ATTR_BOX, chars will be
      mapped to Unicode according to CP437.
    + Added box char support in non-Unicode mode.
      For chars marked as HB_GT_ATTR_BOX, OEM_CHARSET will
      always be used.
    ; NOTE: This way it's possible to use ISO/WIN codepages with
            GTWVT, while still being able to use various drawing
            chars (lines, blocks, arrows).
    ; NOTE: The available set of drawing chars depends on the
            OS OEM_CHARSET mapping _for non-Unicode Harbour_.
            For Unicode Harbour, full CP437 codepage is
            always available.
    ; NOTE: This solution doesn't go as far as (GTWXC) to
            graphically draw / emulate these chars.
    ; TODO: Add HB_GTI_BOXCP support to change hard-wired "EN" CP.

  * include/hbapigt.h
  * include/hbgtcore.h
    ! Moved HB_GT_ATTR_* macros to public headers, because they
      are needed for public API functions.

  * contrib/hbwin/win_reg.prg
    + w32_regRead(): Added second parameter to specify the default
      value returned in case the reg entry doesn't exist.
      If not specified, NIL will be returned, just like before.
    + GetRegistry(): Added 4th parameter with same purpose as above.

  * source/rtl/hbregex.c
    * Minor opt.

  * contrib/hbwin/win_misc.c
    * Added command line option parameter to WIN_RUNDETACHED().

  * include/hbapi.h
    + HB_ERRCODE (to replace ERRCODE)
    + HB_SUCCESS (to replace SUCCESS)
    + HB_FAILURE (to replace FAILURE)

  + contrib/hbwin/win_misc.c
  * contrib/hbwin/common.mak
  * contrib/hbwin/Makefile
    + WIN_SHELLEXECUTE()
      WIN_RUNDETACHED()
      WIN_LOADRESOURCE()
      Added some new Windows API wrappers.
    ; TODO: Add hb_osEncode() to them.

  * source/rtl/diskspac.c
  * source/rtl/disksphb.c
    ! Fixed DISKSPACE() and HB_DISKSPACE() for Darwin.
      Previously they had returned erroneous values.
    ; TOFIX: Probably HB_DISKSPACE() should be implemented for Watcom and CEGCC,
             just like DISKSPACE() is.

  * source/rtl/filesys.c
    ! hb_fsGetAttr() to set the returned attribute to zero
      in case of error.

  * include/hbextern.ch
  * source/rtl/philes.c
    + HB_FSETATTR( <cFileName>, @<nAttr> ) -> <lSuccess>
    + HB_FGETATTR( <cFileName>, <nAttr> ) -> <lSuccess>
    + HB_FSETDATETIME( <cFileName>, [<dDate>], [<cTime HH:MM:SS>] ) -> <lSuccess>

  * source/rtl/direct.c
    ! Fixed DIRECTORY() when called with "V" (label) parameter.
      Tested under Windows. Please test/correct for other platforms.
      On Windows, the dirspec should not contain a filemask in order
      to work.

  * contrib/hbtip/base64x.c
    % HB_BASE64(): Optimized, cleaned.
    ! HB_BASE64(): Removed second parameter allowing to pass the length of
      the string. This could cause GPF if passed incorrectly. Now length
      is simply determined using hb_parclen().
    ; TOFIX: Input string size limit checking.

  * include/hbdefs.h
    + HB_SIZEOFARRAY() macro, which does: ( sizeof( var ) / sizeof( *var ) )
      To be really precise, f.e. all hb_strncpy() calls should use
      'hb_strncpy( d, s, HB_SIZEOFARRAY( d ) );' instead of:
      'hb_strncpy( d, s, sizeof( d ) );' (given that 'd' is allocated at compile time).
      So that the code adapts to changing character sizes (like UTF-16/32).
      It's useful in some other places, too.

  * contrib/hbct/dattime2.c
    * 0 -> FALSE for BOOL types.

  * include/hbextern.ch
  * source/rtl/strmatch.c
    + HB_WILDMATCHI(). Case-instenstive, exact match. First
      two parameters and return value are the same as for
      HB_WILDMATCH().

  * include/hbextern.ch
  * source/rtl/cdpapi.c
    + HB_CDPSELECT() which does the same as HB_SETCODEPAGE(), but
      aligns well with function naming rules and namespace.
      HB_SETCODEPAGE() still works, but usage is not recommended.
    + Added HB_CDPUNIID( <cHarbourCP> ) -> <cCPName>
      This will return the std CP ID of a Harbour CP, or empty
      if the Harbour CP isn't linked.

  * include/hbapi.h
  * source/rtl/is.c
    ! Fixed compile error when HB_CDP_SUPPORT_OFF is defined.
    + Added following functions:
      hb_charIsDigit()
      hb_charIsAlpha()
      hb_charIsLower()
      hb_charIsUpper()

  * include/hbapi.h
    - hb_strUpperCopy() removed. Implementation was missing.

  * source/rtl/strcase.c
    * Minor formatting.

  * source/rtl/filesys.c
    ! hb_fsCurDirBuff() fixed potential buffer overrun by one byte.

  * source/rtl/hbrunfun.c
  * source/rtl/run.c
    ! Fixed missing header hbapiitm.h (after previous local change).

  * include/hbapi.h
  * include/hbset.h
  * include/hbapifs.h
  * include/set.ch
  * source/rtl/hbffind.c
  * source/rtl/gete.c
  * source/rtl/filesys.c
  * source/rtl/hbrunfun.c
  * source/rtl/run.c
  * source/rtl/philes.c
  * source/vm/set.c
  * source/vm/cmdarg.c
    + Added file system CP translation.
      Set( _SET_FNAMECP[, <cCPID> ] ) -> <cOldCPID>
      All operations passing filenames to/from the
      OS will convert them to/from the host CP from/to
      the FS CP specified using _SET_FNAMECP.
    * hb_fsNameConv() extended to deal with CP
      conversion, if requested by the app.
    + hb_fsNameConvFrom() (exported) added to deal
      with CP conversions for filenames received from OS.
    + hb_fsNameConvTo() (exported) added to deal
      with CP conversions for filenames/string sent to the OS.
    + Added hb_setGetFNAMECP() (exported) function.
    + Added hb_setGetFileCPTransTo(), hb_setGetFileCPTransFrom()
      (non-exported) functions.
    + hb_fsCurDirBuff() and hb_fsFindNextLow() extended
      to use hb_fsNameConvFrom().
    + Added hb_fsBaseDirBuff() to return the base
      directory on the C level (based on argv[0]).
    + Added HB_PROGNAME() to return the executable
      program name (based on argv[0]).
    + Added HB_DIRBASE() to return the executable
      base directory (based on argv[0]).
    * Renames done regarding OS/FS CP conversion:
      hb_fsNameConvFrom()        -> hb_osDecode()
      hb_fsNameConvTo()          -> hb_osEncode()
      hb_setGetFileCPTransTo()   -> -
      hb_setGetFileCPTransFrom() -> -
      hb_setGetFNAMECP()         -> hb_setGetOSCODEPAGE()
      _SET_FNAMECP               -> _SET_OSCODEPAGE
    * hb_osDecode()/hb_osEncode() extended to have a second
      parameter BOOL * fFree.
       Changed all calls to handle the case when fFree is set
      to TRUE by hb_osDecode()/hb_osEncode().
    + HB_GETENV(): Added 3rd logical parameter to control wether
      to convert the returned value from OS CP to Harbour CP.
      The default is TRUE to be in sync with GETE[NV]() and the
      rest of core.
    * hb_fsNameConv() is now doing OS CP conversion using std APIs,
      rather than duplicating such logic. I've traded some speed
      for modularity.
    * hb_osDecode/hb_osEncode() function declarations moved to hbapi.h
    * hb_osDecode/hb_osEncode() function definitions moved to set.c
    ; NOTE: None of these were extensively tested, and I tend
            to make mistakes when dealing with pointers.
            It compiles cleanly with BCC, and some basic tests
            worked, but bFree = TRUE codepaths are not yet
            working so this needs more review.

  * source/rtl/teditor.prg
  * source/rtl/tpersist.prg
  * utils/hbmake/hbmake.prg
    * MemoRead() -> hb_MemoRead()

  * contrib/hbct/files.c
    ; TOFIX: Many functions here are possibly not thread safe.
    ; TOFIX: Calling hb_fsFindClose() at app exit (and thus keeping
             the FF handles open for the whole app lifetime) doesn't
             play well with server side apps (as the app may run for
             months or even longer), and even worse, they
             will lock the passed directory so that they cannot be
             removed (maybe even renamed), until the app exists.
             At least on Windows.

  * source/rtl/dirdrive.c
    ! Fixed to use F_ERROR instead of -1.

  * include/hbextern.ch
    ! Added missing HB_GCSTEP().

  * source/vm/extrap.c
    + Added CPU dump code for Windows x64.
    + Enabled module listing for Windows 64-bit platforms.
    % Minor cleanup in Windows x86 CPU dump code.
    + Added TODO for Windows IA64 CPU dump.
    + Added TODO for Windows x64 stack walk, with pointers.
    + Added TOFIX regarding displaying module names in Windows x64 mode.

  * source/rtl/fstemp.c
    ! Minor formatting.

  * source/rtl/gete.c
  * source/rtl/run.c
  * source/rtl/hbrunfun.c
  * source/vm/cmdarg.c
    + Added CP conversion to:
      GETE[NV](), HB_GETENV(), __RUN(), HB_RUN(),
      HB_ARGSTRING(), HB_CMDLINE().

  ; TODO: dbCreateTemp( <cAlias>, <aStruct>, <cRDD>, <cDelimArg>, <nConnection> ) -> <lSuccess>
          Generates and opens a new dbf with a temporary filename
          in exclusive mode, deletes it automatically when closed.
          All indexes created for this table, should ideally have
          the temporary flag on, so those get deleted too, when closed.

  ; TOFIX: hb_regex*() functions will not honor Harbour CP setting,
           when case insensitivity is selected.

  ; TOFIX: hbct / SetFDaTi() to move any local logic into Harbour core
           functions and use a simple Harbour API call only.
           I'm not sure what is the reason with keeping the logic
           duplicated here; if this isn't by intent, this function
           could be much simplified.

  ; TOFIX: Avoid using C level toupper()/tolower()/islower()/isupper()

  ; TOFIX: hb_regexMatch()'s 3rd parameter has a double meaning.
           It controls case-sensitivity (in sync with the documentation),
           but it also controls if hb_regexMatch() behaves like
           hb_regexLike() (.T.), or hb_regexHas() (.F.). This means
           that hb_regexMatch(,, .T.) == hb_regexLike(,, .T.) (case-sensitive) and
                hb_regexMatch(,, .F.) == hb_regexHas(,, .F.) (case-insensitive)
           Maybe this was the intent of the original developers, but
           to me it looks a rather strange behaviour which was added by
           accidentally forgetting about the 3rd parameter already being
           utilized. This either needs to be fixed, or properly documented.
