! removed completely false information about 'LIST &cMacro'
* updated information about FOR EACH
; in general information in this file are outdated and does not
correctly describe current Harbour behavior. I strongly suggest
to not use it in any other documentation. In some spare time
I'll update this file or remove.
* doc/cmpopt.txt
+ added information about unsupported by Clipper syntax extension:
iif( <expr1>, <expr2>, <expr3> ) <op>= <expr4>
* include/hbrddnsx.h
* minor modification in comment
* src/macro/macrolex.c
* accept unconditionally hash 'key => value' operator
* src/rdd/dbfnsx/dbfnsx1.c
! fixed very bad bug in leaf key compression. This problem could be
exploited by keys containing containing CHR( 255 ) in encoded keys
just before trailing empty key characters.
This bug could cause index corruption.
* use hb_xgrabz()
* formatting
* contrib/rddads/ads1.c
* contrib/rddads/adsfunc.c
* contrib/rddads/rddads.h
+ added support for RDDI_INDEXPAGESIZE in ADI indexes
* src/rdd/dbf1.c
* minor cleanup
* include/hbrddcdx.h
* src/rdd/dbfcdx/dbfcdx1.c
+ added support for long index keys when bigger pages are used.
Now maximum index key size is 4082 for 8192 bytes length index pages.
Indexes are critical for database applications so please make
tests with current code and report problems if you find any.
* include/hbrddcdx.h
* src/rdd/dbfcdx/dbfcdx1.c
* renamed CDX_TYPE_TEMPORARY to CDX_TYPE_PARTIAL
* eliminated Temporary member from CDXTAG structure
* cleaned tag signature flag setting to strictly follow
CL5.2 (SIx3) and CL5.3 (COMIX)
* contrib/rddads/ads1.c
* contrib/rddads/adsfunc.c
! check if AE_VALUE_OVERFLOW macro exists before use
! fixed memory leak
% use char* instead of UNSIGNED8* to eliminate unnecessary casting
* use HB_IT_EVALITEM instead of HB_IT_BLOCK
* formatting and minor cleanups
* include/hbrddcdx.h
* src/rdd/dbfcdx/dbfcdx1.c
* modifications for longer index keys when bigger pages are used
(work in progress)
* include/hbrddcdx.h
* src/rdd/dbfcdx/dbfcdx1.c
* force default index page size when CDX header does not contain
Harbour signature
* added RTE when index expression returns item with unsupported
type during indexing
* modifications for longer index keys when bigger pages are used
(work in progress)
* formatting
* include/hbrddcdx.h
* src/rdd/dbfcdx/dbfcdx1.c
* added support for user defined index page size in DBFCDX.
To change page size for newly created index it's enough to call:
hb_rddInfo( RDDI_INDEXPAGESIZE, <nNewSize>,, "DBFCDX" )
DBFCDX accepts page sizes which are power of 2 in from 512 to 8192.
The upper range is my personal decision and can be easy changed
in Harbour source code. 512 is default CDX index page size and
only such indexes can be read by other RDDs.
In some cases bigger pages can increase performance and reduce
index size. In local networks probably 1024 should give optimal
performance because can be transferred in single ethernet frame.
Just make a tests.
; In next step I plan to add support for longer index keys when
bigger pages are used.
* utils/hbmk2/hbmk2.prg
! added -stop fix borrowed from Viktor's branch
* include/hbrddcdx.h
* src/rdd/dbfcdx/dbfcdx1.c
+ added support for large index files over 4GB length.
These are slightly modified CDX indexes which stores index page numbers
instead of index page offsets inside index file. This trick increase
maximum index files size from 2^32 (4GB) to 2^41 (2TB). This index
format is enabled automatically when DB_DBFLOCK_HB64 is used. This is
the same behavior as in DBFNTX and DBFNSX for which I added support
for large indexes (up to 4TB) few years ago.
Warning: new CDX indexes are not backward compatible and cannot be
read by other systems or older [x]Harbour versions.
If you try to open new indexes using older [x]Harbour RDDs
then RTE "DBFCDX/1012 Corruption detected" is generated.
When current Harbour *DBFCDX/SIXCDX RDD open index file
then it automatically recognize type of index file so it
will work correctly with both versions without any problem.
In short words: People using DB_DBFLOCK_HB64 should remember
that after reindexing with new Harbour applications old ones
cannot read new CDX indexes.
; In next step I plan to add support for user defined page size in CDX
index files.
* doc/xhb-diff.txt
* added information about extended CDX format to section "NATIVE RDDs"
* src/rdd/dbfcdx/dbfcdx1.c
* src/rdd/dbfnsx/dbfnsx1.c
* src/rdd/dbfntx/dbfntx1.c
* disable record readahead buffer used during indexing when only
one record can be stored inside
! generate RTE when data cannot be read into record readahead buffer
during indexing
* src/rtl/gtxwc/gtxwc.c
! fixed size of picture shown by HB_GTI_DISPIMAGE
! fixed indexes used to restore text data after
hb_gtInfo( HB_GTI_DISPIMAGE, "" )
* src/Makefile
! fixed to only include compilable GTs in Harbour dynlib
(borrowed from Viktor's fork)
* src/rtl/gtxwc/gtxwc.c
+ redraw screen area when empty string is passed as image body
to HB_GTI_DISPIMAGE, i.e.:
hb_gtInfo( HB_GTI_DISPIMAGE, "" [, <aCords> ] )
If <aCords> is not given then whole screen is refreshed.
* src/vm/arrays.c
! added protection against internal error when ACOPY() is executed
with the same array passed as source and target without any indexes
which can force item move. Now ACOPY() works like in Cl*pper.
* include/hbdefs.h
* use strict aliasing friendly conversions in MSC builds which support
intrinsic version of _byteswap_*() functions.
It should also pacify some of MSC warnings.
* include/hbdefs.h
* src/rdd/dbffpt/dbffpt1.c
* minor formatting
* contrib/gtwvg/wvgcore.c
! fixed HANDLE to LONG casting - it's bug in 64 bit builds
* include/hbcomp.h
* include/hbcompdf.h
* src/compiler/hbmain.c
* src/compiler/harbour.y
* src/compiler/harbour.yyc
* replaced 'char' type holder with 'HB_BYTE' - this is part of never
finished code which is completely dummy in current compiler and above
modification is only to pacify warnings which are real bugs in existing
implementation. I do not plan to modify or fix this code. I'll remove
it working on fully functional strong typing implementation.
* src/compiler/harbour.y
* src/macro/macro.y
* disabled 4244 and 4702 warnings in MSVC builds - this warnings are
from code generated by bison and they are out of our direct control
* src/compiler/harbour.yyc
* src/compiler/harbour.yyh
* src/macro/macro.yyc
* src/macro/macro.yyh
* regenerated
* src/3rd/tiff/tiff.dif
* src/3rd/tiff/tiffconf.h
* do not redefine O_* macros in all *nix builds
* src/compiler/harbour.yyc
* src/compiler/harbour.yyh
* src/macro/macro.yyc
* src/macro/macro.yyh
* regenerated with bison 3.0.2.
* src/rtl/hbcom.c
! fixed compilation with OpenWatcom for Linux
* src/rtl/hbsocket.c
* pacified warning in OpenWatcom Linux builds
* src/rtl/hbjson.c
* own code for conversion integer numbers
* contrib/gtqtc/gtqtc1.cpp
+ added support for decoded image data passed to HB_GTI_DISPIMAGE like
in GTXWC. Supported formats are RGB32, RGB16 and MONO bitmap.
Unlike GTXWC GTQTC rescales bitmap to passed cords.
* src/rdd/wafunc.c
! fixed very bad bug introduced in previous modification - in fact
potential problem existed from the beginning anyhow recent modification
allow to exploit it in all complex index expressions.
* src/rdd/wafunc.c
% use dynamic symbol pointer to find field index
* src/rdd/workarea.c
* set default maximum field size to HB_SYMBOL_NAME_LEN characters
(by default in Harbour builds HB_SYMBOL_NAME_LEN is 63)
Some RDDs may set longer names but it will be respected only by
FieldName() function and in all other cases only HB_SYMBOL_NAME_LEN
characters is significant for Harbour so such decision should be
well thought by RDD authors because it may confuse users.
Warning: all 3-rd party RDDs which need to force shorter names
should update uiMaxFieldNameLength in their NEW() method
just after SUPER_NEW() call, i.e. like in core DBF RDD.
! respect uiMaxFieldNameLength when new fields are added
* src/rdd/dbf1.c
* set maximum field size to 10 characters
* contrib/rddsql/sqlbase.c
- removed code used to set uiMaxFieldNameLength to HB_SYMBOL_NAME_LEN.
Now it's default field length value for each RDD unless it does not
change it.
* contrib/rddads/ads1.c
* minor modification in adsFieldName()
* contrib/hbwin/wapi_winbase.c
+ added support for FORMAT_MESSAGE_ALLOCATE_BUFFER and 6-th <nSize>
parameter to wapi_FormatMessage() function. The 6-th <nSize> parameter
has higher priority then size of string passed in the 5-th parameter.
! fixed potential memory leak
* include/hbapi.h
* src/common/hbstr.c
+ added new function hb_strAtI() - it works like hb_strAt() but it
ignores the case of the ASCII characters
* src/rtl/ati.c
* renamed local static function hb_strAtI() to s_strAtI() to avoid
conflict with new public hb_strAtI() function.
* contrib/xhb/xhbat.c
- removed local static function hb_strAtI() - current public hb_strAtI()
is compatible with it.
* contrib/sddsqlt3/core.c
+ added new code to set column type giving the highest priority SQLITE3
declared column types.
Please test - I haven't made any.
! do not cast floating point values to integer
* contrib/hbwin/hbwin.hbx
* contrib/hbwin/win_prn2.c
! fixed win_printerGetDefault() in Win9x builds - fix and some
formatting and casting borrowed from Viktor's fork.
+ added new PRG function:
win_PrintDataRaw( <cPrinter>, <cData> [, <cDocName>] )
-> <nBytesPrinted>
It's similar to win_PrintFileRaw() but sends to given printer passed
in 2-nd parameter <cData> instead of file body.
On error it returns negative value.
* cleaned casting and minor formatting
* src/rtl/gtxwc/gtxwc.c
+ added support for HB_GTI_DISPIMAGE. It's slightly modified code sent
by Rolf to Harbour devel list. In comparison to original version it
supports <nDepth> as 4-th item of array with bitmap description to use
with some other GTs which can support different color depths or can
make conversion. It also supports bitmaps passed as strings.
% slightly improved HB_GFX_GETPIXEL
* contrib/gtqtc/gtqtc1.cpp
* src/rtl/gtwvt/gtwvt.c
* contrib/gtwvg/gtwvgd.c
* use hb_vmRequestQuit() instead of hb_vmRequestCancel() when
close event is received - it is GTXWC compatible behavior and
allows to execute user EXIT PROCEDUREs.
Please also remember that all ALWAYS sections are executed too
regardles of requested event (QUIT, BREAK, CANCEL)
* src/rtl/gtwvt/gtwvt.c
! fixed processing WM_QUERYENDSESSION and WM_ENDSESSION messages.
Now GTWVT applications do not interrupt system shutdown process
and do not close application if other process interrupted it.
In the future we can also add support for blocking system shutdown
operation, i.e. using HB_GTI_CLOSEMODE as bitfield, anyhow before
we begin to change it we should agree final version.
! applied Rolf's patch which fixes circle and ellipse cords.
I haven't tested it and I hope that they were verified visually
on the screen - some of Windows GUI functions do not access
border points.
* src/common/hbdate.c
! fixed typo in hb_timeUTCOffset() - this code was used in POSIX
systems which do not support gmtime_r()/localtime_r() - many
thanks to Teo.
* src/debug/dbgentry.c
* src/debug/debugger.prg
* prepare the code to return error object when evaluated expression
fails as proposed by Teo. This functionality is not enabled yet.
I'm waiting for information about current public debugger API used
in 3-rd party projects before I decide to change it.
* include/hbdebug.ch
+ added HB_DBG_* constant values for arrays returned by __dbg*()
functions
* include/hbset.h
* src/vm/set.c
+ added new C function: hb_setGetItem();
* src/debug/dbgentry.c
* use HB_DBG_* constant values
+ added new debugger function: __dbgGetSETs() - it returns array with
all HVM SETs: { { <nSet>, <cSetName>, <xSetValue> }, ... }
% optimized hb_dbgActivateCallStackArray() and hb_dbgActivateModuleArray()
* src/debug/debugger.prg
* use HB_DBG_* constant values
* use __dbgGetSETs() for "System Settings" window
+ added support for Harbour SET extensions
* ChangeLog.txt
* updated description for structure of array returned
by __dbgGetBreakPoints()
* contrib/hbmysql/tmysql.prg
* added support for nFlags in TMySQLServer constructor as
suggested by Fernando Athayde
* src/rtl/gtcgi/gtcgi.c
% replaced hb_cdpnDup() with hb_cdpnDup3() to eliminate unnecessary
memory block duplicating when translation is not activated.
* src/vm/itemapi.c
* removed old ugly hack used to mark infinite or undefined double
value using double item length field. The code which created such
item have been eliminated many years ago.
* use HB_DEFAULT_WIDTH instead of hardcoded 99 to force numeric value
length recalculation.
* src/vm/estack.c
* always set NIL in item allocated by hb_stackAllocItem() when it's
used as function. In internal macro this step is missing so allocated
item still may contain other simple value. All places in HVM where
hb_stackAllocItem() is used are safe for such situation (I've just
verified them again).
It fixes problem reported by Mindaugas when hb_stackAllocItem()
was used inside DBFFPT as temporary item and could unintentionally
change memo type if allocated item containes previous numeric
value in valid memo type range.
* src/rdd/wafunc.c
* src/vm/hvm.c
* src/vm/memvars.c
* clear passed item before RTE when accessed memvar or field does not
exists
* src/vm/hashfunc.c
! set default value before decoding 2-nd logical parameter in
hb_HAutoAdd() function. It fixes ambiguity reported by Mindaugas.
* src/debug/dbgentry.c
* moved code used to create callstack array to separate
function hb_dbgActivateCallStackArray()
* changed function order to avoid some forward declarations
* src/debug/dbgwa.prg
! fixed position of some item in F6-WA window
* include/hbvm.h
* src/vm/hvm.c
+ added new HVM function: hb_vmTryEval()
This function tries to execute given block or function
inside BEGIN SEQUENCE / RECOVER oErr / END SEQUENCE statement.
It return HB_TRUE if it was executed without any problem and
HB_FALSE otherwise. Result or RTE object is stored in 1-st
parameter and should be freed by the caller using hb_itemRelese()
* src/debug/dbgentry.c
! use hb_vmTryEval() instead of hb_itemDo() to evaluate trace point
expressions. Now debugger does not crash when user sets tracepoint
expression which cannot be evaluated in executed context.
! allow to use expressions with more then 99 variables
! added missing protections against GPF when wrong parameters are
passed to __dbg*() functions
* keep original trace and watch point expression for farther
processing
* replaced IS_IDENT_*() macros with HB_IS*IDCHAR()
+ added new debuger function:
__dbgGetWatchPoints() -> <aWatchTracePoints>
<aWatchTracePoints> contains subarrays describing trace and watch
points:
{ <cExpression>, <lTracePoint>, <lValid>, <xResult> }
It was the last function necessary to extract all information
about debugged context from core internals. Now it's possible
to create fully functional standalone debugger without storing
and updating locally any information about debugger state.
All such information can be accessed at any time using __dbg*()
functions.
It should greatly simplify creating 3-rd party debuggers like
HWDebug or HBQTDebug.
* src/debug/debugger.prg
! fixed callstack window updating during tracing and stepping.
Tanks to Rolf for reporting the problem.
* contrib/hbct/ctwin.c
! fixed typo in window area checking when current window is 0
It fixes problem with debugger reported by Rolf.
* src/debug/dbgentry.c
% few optimizations
! added few protections against GPF when wrong parameters are passed
! fixed missing support for symbol, date and timestamp values in
tracepoints
+ added __dbgCntWatch()
* src/rtl/filesys.c
* src/rtl/hbproces.c
* pacified warning in more aggressive way for newer GCC versions
* include/harbour.hbx
* refreshed
* include/harbour.hbx
* src/rtl/val.c
+ added new function: hb_Val( <cStr> [, <nLen> ] ) -> <nVal>
it works like a val but set length for numeric result to passed string
length or <nLen> parameter if is large enough.
* src/rtl/tget.prg
! use hb_Val() instead of Val() for numeric GETs to replicate Clipper
behavior for pictures longer then 10 characters.
* src/rtl/itemseri.c
* minor update in comments
* contrib/hbct/ctwin.c
* src/rtl/hbgtcore.c
! fixed GTCTW window handle save/restore on debugger activation
I broke in 107b36e847
Thanks to Rolf for the info and patch.
* contrib/hbziparc/ziparc.prg
* synced with Viktor's branch.
This code should contain Rolf fixes. Please test.
* src/rtl/gtwin/gtwin.c
+ added support for disabling [x] button of console window in older
MS-Windows versions which do not have GetConsoleWindow() function,
i.e. Win9x/ME
* include/hbserial.ch
* src/rtl/itemseri.c
+ added HB_SERIALIZE_IGNOREREF flag.
This flag fully disables logic used to detect multireferences to the
same complex (sub)items like arrays or hashes. It increses the speed
of serialization but serialized data does not contain any information
about refences, i.e. aVal[ 1 ] and aVal[ 2 ] in code below:
aSub := { 1, 2, 3 }
aVal := { aSub, aSub }
are serialized as separated arrays. Additionally items with cyclic
references like:
aSub[ 2 ] := aSub
cannot be serialized at all with HB_SERIALIZE_IGNOREREF flag because
it will create infinite serialization loop and crash with out of
memory message.
* src/rtl/itemseri.c
% rewritten algorithm used to detect cyclic and multi references in
serialized items. The original algorithm has very high overhead when
huge arrays were serialized, i.e. serialization of array with 1'000'000
of subarrays needed about 30 minutes on my i5@3.30GHz. Now it needs
less then a second and this time is only a little bit bigger then
used by serialization with HB_SERIALIZE_IGNOREREF flag.
This modification improve performance also in other code using Harbour
serialization mechanism like I18N files, HBNETIO, GTNET, ... when large
arrays or hashes are saved or transmitted.
* include/hbapi.h
* include/hbapicls.h
* src/vm/arrays.c
* src/vm/classes.c
* src/vm/hashes.c
* src/vm/itemapi.c
* replaced algorithm used to detect cyclic and multi references in
array and hash clone operations with new one similar to current
item serial code. The speed improvement for very large arrays is
the same as in case of serialization code.
* src/rtl/gtsln/mousesln.c
! typo in while loop - synced with Viktor's branch
* contrib/hbtip/mail.prg
! fixed missing 1-st adress in CC and BCC parameters - many
for information about the bug and patch
* contrib/hbtip/sendmail.prg
! typo in comment - thanks to Heinz V Bergen too
* src/rtl/gtwvt/gtwvt.c
* some minor modification to sync code with Vitkor's branch
* src/vm/hvm.c
* src/vm/itemapi.c
* small optimization in string comparison
* src/debug/dbgentry.c
* src/debug/debugger.prg
* src/debug/tbrwtext.prg
* use one function to divide text per lines with the same rules
as used in Cl*pper and Harbour PP.
! fixed input line size in SET edit window
! fixed validation in some input boxes
* process only 1-st parameter in some commands just like Cl*pper does
+ added support for FILE OPEN <name> command
! fixed CALLSTACK ON | OFF command
! fixed NUM command
+ added support for VIEW <fileName> command
+ added support for LOCATE GOTOLINE <line> command
+ added support for LOCATE FIND <text> command
+ added support for RUN SPEED <num> command
+ added support for LIST WP|TP command
+ added support for BP <funcName> command
+ added support for DELETE ALL [TP|WP] and DELETE WP|TP <number>
commands
% few optimizations and some other minor fixes
