* harbour/src/vm/classes.c
% small optimization in __CLSGetProperties() function
* harbour/src/rtl/tpersist.prg
! force linkin ARRAY() function when HBPersistent class is used
! use hb_ValToExp() instead of local ValToText() function which
didn't work correctly for memos and some other types
! fixed infinite loop in HBPersistent:LoadFromText() used with
empty text. The problem was also exploited by :LoadFromFile()
method if file does not exists or it's empty()
! fixed deserialization of strings containing "=" char inside
! fixed deserialization of strings containing "::"
! added support for decoding nested objects - the code was not
finished and this part was not implemented at all
+ added support for serialized text using ":=" assign operator
instead of "="
* use ":=" instead of "=" as assign operator in new serialized
text
+ ignore lines starting with "//" and added support for files
which do not start with OBJECT directive
* ignore pointer and codeblock items stored in instance variables
during serialization
; now HBPersistent class in Harbour should read serialized files
created in xHarbour with few exceptions:
- Harbour does not allow to serialize codeblocks
See "CODEBLOCK SERIALIZATION / DESERIALIZATION" in
doc/xhb-diff.txt for the reasons.
If Harbour application restores xHarbour HBPersistent files
with serialized codeblocks then RTE
Undefined function: HB_RESTOREBLOCK
is generated.
- xHarbour serialize pointer items as numeric items
saved in hexadecimal notation. Then restore them as numbers.
- HBPersistent does not support hash arrays - they are
serialized by default serialization code used by both
compilers to generate expressions.
In Harbour it's done by hb_valToExp() function and
in xHarbour it's ValToPrg() is used.
ValToPrg() does not create valid macrocompiler expressions
for arrays and objects so HBPersistent files created
by xHarbour are broken and cannot be correctly deserialized.
It happens if objects has hash arrays in instance variables
and these hash arrays contain normal arrays or object
If Harbour application restores such xHarbour HBPersistent
file then RTE "Syntax error: &" is generated.
; xHarbour encapsulates deserialization code inside TRY/CATCH/END
statement saving errors to trace.log file. Harbour generates RTE.
If programmer needs similar behavior then he should
call :LoadFromText() and :LoadFromFile() methods inside
BEGIN SEQUENCE [ / RECOVER ... ] / END SEQUENCE
statement.
; xHarbour reinitialize all or properties instance variables to
default state inside :LoadFromText() and :LoadFromFile() methods.
The 3-rd parameter in above method <lPropertiesOnly> allows to
chose which install variables should be reinitialized:
all (default) or properties only.
Harbour does not have such functionality.
If programmer needs it then he should reinitialize them himself.
It can be easy done be simple function.
Alternatively we can implement this functionality but in such
case I'd suggest to define three actions for such switch:
none (default), all, properties only.
; Harbour does not support 2-nd parameter <lIgnoreBadIVars> which
exist in xHarbour versions of HBPersistent:LoadFromText() and
HBPersistent:LoadFromFile():
If necessary we can implement it though it's usable only if we
want to ignore some wrong lines and process others.
; Warning: Neither Harbour nor xHarbour supports arrays and objects
with cyclic references in HBPersistent code - infinite
loop appears in such case.
; I've never used HBPersistent and the state of the previous
HBPersistent code in Harbour suggests that no one used it for
some serious jobs so I'm open for any opinions and suggestions
about it from xHarbour users.
* harbour/src/compiler/harbour.y

* harbour/include/harbour.hbx
+ added new PRG function:
HB_LANGNEW( <cNewLangId>, <cNewLangCpId>,
<cLangId>, <cLangCpId> ) -> <lOK>
this function dynamically creates new lang module translating
existing one then registers it, i.e.:
request HB_CODEPAGE_DE850

request HB_LANG_DE
HB_LANGNEW( "DEISO", "DEISO", "DE", "DE850" )
SET( _SET_LANGUAGE, "DEISO" )

+ added support for custom sorting redirected from HVM
+ added support for custom character indexes in strings
+ added support for custom character flags (upper, lower, alpha, digit)
+ added support for custom upper/lower conversions
+ added support for CPs using unicode character values instead of
ASCII ones
+ added new CP functions which respects custom CP settings:
hb_cdpUpperWC(), hb_cdpTextLen(), hb_cdpTextPos(),
hb_cdpTextPosEx(), hb_cdpTextGetU16(), hb_cdpTextPutU16(),
hb_cdpCharEq(), hb_cdpCharCaseEq()
+ added new conversion functions:
hb_cdpGetUC(), hb_cdpGetWC(), hb_cdpGetU16Ctrl()
+ added macros to detect codepage parameters:
HB_CDP_ISBINSORT() - codepage uses simple binary sorting
HB_CDP_ISCUSTOM() - codepage uses custom string decoding
HB_CDP_ISCHARIDX() - codepage use character indexes instead
of bytes ones
HB_CDP_ISCHARUNI() - CHR(), ASC() and similar functions operates
on Unicode values instead of bytes
HB_CDP_ISUTF8() - codepage uses UTF-8 encoding
* harbour/include/inkey.ch
- removed HB_INKEY_EXTENDED - it was not used in Harbour
+ added new flag HB_INKEY_EXT - it allows to used different
event encoding system with automatic translation to
standard Clipper values. It will be used in the future
as base for low level GTs code. Now it's possible to
selectively switch to the new system. New codes are
unique and do not interacts with Clipper.
+ added HB_INKEY_ALL macro - it's similar to INKEY_ALL but
enables also GTEVENT keys.
* harbour/include/hbgtcore.h
* harbour/src/rtl/hbgtcore.c
* changed character values in internal screen buffer to unicode.
Warning: this modification interacts with SAVESCREE()/RESTSCREEN()
data. Now all GTs uses extended definition. If somene
has code which needs VGA like screen buffers returned
by SAVESCREE() then it can be forced by
hb_gtInfo( HB_GTI_COMPATBUFFER, .t. )
Anyhow it will for to use only one CP in output.
+ added new GT methods which operated on HB_WCHAR values
* modified existing methods using HB_WCHAR/HB_USHORT parameters
to operate on HB_WCHAR values
+ added codepage conversion code directly to core code so it can
be eliminated from low level GT drivers which do not need some
special operations on it.
+ added support for extended inkey codes, they allow to encoded
unicode values, mouse events with flags, keyboard events with
modifier flags (shift,alt,ctrl,...), etc.
Now in low level GT code only unicode key values are used but
I plan to updated all GTs and switch to new code - it should
resolve many small problems inheriting with Clipper inkey codes.
* harbour/include/hbapifs.h
* moved hb_fsNameConvU16() definition from hbapicdp.h to hbapifs.h
* harbour/include/hbxvm.h
- removed comment copied by mistake from GT header file
* harbour/include/hbwinuni.h
* changed HB_CHARDUP() and HB_CHARDUPN() macros - now they
operate on functions which can be used without active HVM.
In such case ANSI CP is used as source encoding.
+ added new macros: HB_OSSTRDUP() and HB_OSSTRDUP2().
They make conversions from OS encoding to HVM one.
They can be used without active HVM and in such case ANSI CP
is used as destination encoding.
* harbour/include/hbapi.h
* harbour/src/vm/cmdarg.c
+ added new function hb_cmdargProgName()
It returns application name with path or NULL if not set,
caller must free returned value with hb_xfree() if not NULL.
The string is in HVM encoding so it does not need any additional
encodings.
* modified hb_cmdargString() to return strings in HVM encoding.
% some small code optimizations
; NOTE: parameters passed to MS-WINDOWS GUI programs which use
WinMain() instead of main() as startup entry are translated
to ANSICP before they can be accessed by application.
This can be eliminated though not for console programs
using where C compiler makes such translation to main()
parameters.
in all systems parameters are passed to application
startup and init functions before programmer can set OS CP.
This can be resolved by adding:
INIT PROC CLIPINIT()
SET( _SET_CODEPAGE, <userCP> )
SET( _SET_OSCODEPAGE, <systemCP> )
RETURN
to linked code. INIT procedures called CLIPINIT() are
executed before any other ones.
* harbour/include/hbapi.h
* harbour/src/vm/set.c
+ added new functions for CP converisons which can be used with
and without active HVM:
hb_osStrEncode(), hb_osStrEncodeN(),
hb_osStrDecode(), hb_osStrDecode2(),
hb_osStrU16Encode(), hb_osStrU16EncodeN(),
hb_osStrU16Decode(), hb_osStrU16Decode2(),
* harbour/include/hbvm.h
* harbour/src/vm/hvm.c
+ added new function hb_vmIsReady() - it's similar to hb_vmActive()
but it also checks if current thread has active HVM stack.
* moved hb_cdpReleaseAll() to the end of HVM cleanup code so
CP conversions are longer active.
* harbour/include/hbcomp.h
* harbour/src/compiler/cmdcheck.c
* harbour/src/compiler/hbusage.c
* harbour/src/common/expropt2.c
+ added new compiler switch:
-ku - strings in user encoding
Now it informs compiler that strings use custom encoding so some
optimizations which are byte oriented cannot be used.
It's possible that in the future we will change above definition
to sth like: "strings in UTF8 encoding" but now I would like to
keep more general.
* harbour/src/vm/macro.c
* inform macrocompiler about custom CPs using own character indexes
to disable byte oriented optimizations.
* harbour/include/hbapigt.h
* harbour/src/rtl/gtapi.c
* harbour/src/rtl/inkeyapi.c
+ added HB_B_*_W macros with unicode box character definitions
+ added HB_MBUTTON_* macros
+ added new GT functions: hb_gtHostCP() and hb_gtBoxCP() which
allows to extract CPs used in translations by GTs.
+ added new function hb_inkeyKeyString() - it converts inkey value
to corresponding string
+ added new function hb_inkeyKeyStd() - it converts new extended
key value to standard Clipper one.
* harbour/include/hbapifs.h
* harbour/src/common/hbffind.c
* moved OS codepage translations fully to hb_fsFind*() functions.
It fixes few problems which existed before, i.e. double CP
conversions in MS-Windows builds and simplifies upper level code.
* harbour/src/pp/hbpp.c
* harbour/src/rtl/direct.c
* harbour/src/rtl/fssize.c
* harbour/src/rtl/file.c
* harbour/contrib/hbct/files.c
* eliminated not longer necessary CP conversions in code calling
hb_fsFind*() functions.
* harbour/src/common/hbgete.c
* moved OS codepage translations to hb_getenv(), hb_getenv_buffer()
and hb_setenv() functions. It fixes few problems which existed
before, i.e. double CP conversions in MS-Windows builds and
simplifies upper level code.
* harbour/src/rtl/net.c
* harbour/src/rtl/gete.c
* eliminated not longer necessary CP conversions in code calling
hb_getenv()/hb_setenv() functions.
; NOTE: additional parameters in HB_GETENV() and HB_SETENV() which
disabled CP conversions are not longer supported.
They were strictly platform dependent and ignored in chosen
cases (i.e. in MS-Windows UNICODE builds we always have to
convert strings transferred between HVM and OS. If someone
needs old functionality for other platform then he should
temporary disable _SET_OSCODEPAGE.

unicode/character operations on strings:
HB_UCHAR( <nCode> ) -> <cText>
return string with U+nCode character in HVM CP encoding
HB_BCHAR( <nCode> ) -> <cText>
return 1 byte string with <nCode> value
HB_UCODE( <cText> ) -> <nCode>
return unicode value of 1-st character (not byte) in given string
HB_BCODE( <cText> ) -> <nCode>
return value of 1-st byte in given string
HB_ULEN( <cText> ) -> <nChars>
return string length in characters
HB_BLEN( <cText> ) -> <nBytes>
return string length in bytes
HB_UPEEK( <cText>, <n> ) -> <nCode>
return unicode value of <n>-th character in given string
HB_BPEEK( <cText>, <n> ) -> <nCode>
return value of <n>-th byte in given string
HB_UPOKE( [@]<cText>, <n>, <nVal> ) -> <cText>
change <n>-th character in given string to unicode <nVal> one and
return modified text
HB_BPOKE( [@]<cText>, <n>, <nVal> ) -> <cText>
change <n>-th byte in given string to <nVal> and return modified

* harbour/src/codepage/cp_utf8.c

* replaced UTF8ASC with new CP: UTF8EX
This CP uses character indexes instead of bytes one
and operates on unicode characters flags.
Tables for upper/lower conversions and upper/lower/alpha/digit
flags were generated automatically from
http://www.unicode.org/Public/UNIDATA/UnicodeData.txt
It also uses custom collation rules. It's very simple one
level sorting based on UTF8 C collation.
If someone needs some advanced sorting rules, then it's enough
to create copy of this cp with user custom version of UTF8_cmp()
and UTF8_cmpi() functions, i.e. they can be redirected to some
external library like ICU (icu-project.org).
* harbour/contrib/hbct/ctwin.c

% small optimization for other systems
* harbour/contrib/hbfship/exec.c
* use hb_cmdargProgName() in EXECNAME()
+ harbour/tests/uc16_gen.prg

; It was quite big peace of modifications and for sure not everything
is well tested so please make test and report problems you will find.
; This is basic version which introduce to HVM CPs with custom encodings.
Some contrib code has to be updated to work correctly with it.
I hope that developers interesting in will make necessary updates.
I haven't touched GTWVW code at all - sorry but it needs very serious
work to make it production ready and fix all existing problems.
; Special thanks to OTC - this firm sponsored adding basic UTF8 support
to HVM.
* src/vm/set.c
! SET( _SET_DEVICE ) to accept anything starting with "PRIN"
as "PRINTER" for Cl*pper compatibility.
* src/rtl/filesys.c
! use utimes() instead of utime() on non-watcom linux platform
to avoid warning (and to follow the other similar utimes() call).
; lightly tested, review me
* src/vm/hashes.c
* src/vm/hashfunc.c
+ implemented posibility to use hashes a sorted arays with binary search.
Implemented HB_BOOL hb_hashScanSoft( pHash, pKey, &nPos ). Function
if similar to, but returns nPos even if pKey is not found in pHash.
Extended HB_HHASKEY( aHash, xKey [, @nPos ] ) --> lFound
Function optionaly returns position of the item with a largest key
smaller or equal to xKey. If xKey is less than all keys in hash,
zero position is returned. I.e.,
aHash := {10=>, 20=>}
? HB_HHASKEY( aHash, 5, @nPos ), nPos // .F. 0
? HB_HHASKEY( aHash, 10, @nPos ), nPos // .T. 1
? HB_HHASKEY( aHash, 15, @nPos ), nPos // .F. 1
? HB_HHASKEY( aHash, 20, @nPos ), nPos // .T. 2
? HB_HHASKEY( aHash, 25, @nPos ), nPos // .F. 2
* harbour/include/hbhrb.ch
* harbour/src/vm/runner.c
* disabled access to INIT and EXIT functions in
HB_HRBGETFUNSYM() and HB_HRBGETFUNLIST()
+ added 2-nd parameter <nType> to HB_HRBGETFUNLIST()
HB_HRBGETFUNLIST( <pHRB> [, <nType>] ) -> <aFuncList>
<nType> is defined in hbhrb.ch:
HB_HRB_FUNC_PUBLIC - locally defined public functions
HB_HRB_FUNC_STATIC - locally defined static functions
HB_HRB_FUNC_LOCAL - locally defined functions
HB_HRB_FUNC_EXTERN - external functions used in HRB module
* harbour/include/hbrdddbf.h
* modified DB_DBFLOCK_HB64 locking scheme
- extended RLOCK/FLOCK area from 2^31-2 to 2^32-2
it effectively changes maximum number of records in this
locking scheme to 4'294'967'294
- use COMIX like hyper locking mode
it should increase performance
Warning: INCOMPATIBLE!
all applications using DB_DBFLOCK_HB64 locking mode should
be updated - it is not safe to concurrently access the
same files using programs compiled with older Harbour
versions and current one.
* renamed the following DB_DBFLOCK_* macros:
DB_DBFLOCK_CLIP to DB_DBFLOCK_CLIPPER
DB_DBFLOCK_CL53 to DB_DBFLOCK_COMIX
DB_DBFLOCK_CL53EXT to DB_DBFLOCK_HB32
* added new locking scheme: DB_DBFLOCK_CLIPPER2
This locking scheme is designed to replicate _real_ locking scheme
used by Cl*pper applications linked with NTXLOCK2.OBJ
It's different then the documented one.
; Now Harbour supports the following locking schemes:
DB_DBFLOCK_CLIPPER 1 default Clipper locking scheme
DB_DBFLOCK_COMIX 2 COMIX and CL53 DBFCDX hyper locking scheme
DB_DBFLOCK_VFP 3 [V]FP, CL52 DBFCDX, SIx3 SIXCDX, CDXLOCK.OBJ
DB_DBFLOCK_HB32 4 Harbour hyper locking scheme for 32bit file API
DB_DBFLOCK_HB64 5 Harbour hyper locking scheme for 64bit file API
DB_DBFLOCK_CLIPPER2 6 extended Clipper locking scheme NTXLOCK2.OBJ

* harbour/src/rdd/dbfcdx/dbfcdx1.c
+ finished support for COMIX like hyper locking.
This modification enables periodical switch to write locks
by readers to eliminate starvation effect on some systems
where many readers can completely block writer.
By default readers use exclusive lock once per each 16 operations.
+ added optional support for delayed index write locks (flush locks)
in hyper locking modes.
If index RDD can use such locks then write lock can be divided into
two parts:
1) block writers and new readers (write lock)
[prepare index modifications in memory]
2) wait for old readers still active (flush lock)
[write modifications to index file]
[release locks]
This mode reduces time when index is locked exclusively increasing
reader performance and also increase writer performance because
waiting for active readers it can prepare index modifications in
memory.
* harbour/src/rdd/dbfcdx/dbfcdx1.c
+ added support for delayed index write locks (flush locks) in DBFCDX
* harbour/src/rtl/filebuf.c
* automatically change write file locks to read locks when file is
open in readonly mode in POSIX systems.
* harbour/src/vm/classes.c
* disabled inheriting of class variables values from ancestor classes
when new class is dynamically created.
Warning: INCOMPATIBLE!
This modification is not backward compatible and can
interact with some existing code which has to be updated
for new behavior.
* harbour/src/vm/fm.c
! do not enable by default DLMALLOC in WinCE builds.
It was the source of problems reported by Jarek with file read/write
operation in WinCE builds. Now it should work correctly - please
make some tests with real devices - I used emulator only.
* harbour/contrib/hbwin/wapi_wingdi_font.c
+ added WAPI_ADDFONTRESOURCE() and WAPI_REMOVEFONTRESOURCE()
* harbour/src/vm/classes.c
! added missing initialization of onError and destructor flags.
The problem could be exploited when class inherits from more
then one parent classes and onError handler[s] or destructor[s]
were neither defined in the class nor in the first ancestor.
* harbour/contrib/hbwin/olecore.c
+ added helper PRG functions:
__oleInvokeMethod(), __oleInvokePut(), __oleInvokeGet(),
__oleGetNameId()
* harbour/src/vm/runner.c
* do not execute EXIT procedures inside HB_HRBDO() call.
This modification allows to call HB_HRBDO() more then
once for the same HRB module without activating INIT
and EXIT procedures on each call. EXIT procedures will
be activated when HRB modules is unloaded or on HVM QUIT.
* harbour/contrib/hbwin/axcore.c
! cleaned casting
* harbour/include/hbstack.h
* harbour/src/vm/estack.c
+ added internal function hb_stackLockCount()
* harbour/src/vm/hvm.c
* modified hb_vmRequestReenter() to return HB_FALSE instead of GPF
when called from non HVM thread.
* extended hb_vmRequestReenter[Ext]()/hb_vmRequestRestore() to
save and restore HVM stack lock state and lock HVM stack before
successful return.
This extensions is critical for MT applications which need
to safely reenter HVM also from code encapsulated inside unknown
number of hb_vnUnlock()/hb_vnLock() calls.

job started many years ago.
; this also means that windows.h and os2.h will no longer be
included by Harbour headers, HB_OS_WIN_USED is thus ineffective,
so if someone needs these headers to access system APIs, they
should be manually included in each source file. Some old
hacks have also been removed which disabled some Clipper
compatibility macros/types in compatibility headers (clipdefs.h, *.api),
if someone uses these alongside windows.h/os2.h inclusion, it will
be broken, here the strategy is to move to Harbour types and
Harbour API headers, simply Clipper headers and newer OS headers
are not compatible.
; HB_DONT_DEFINE_BASIC_TYPES is not effective anymore.
; INKEY_RAW is no more, use HB_INKEY_RAW instead.
; NEXTKEY() hidden parameter extension is disabled. Use HB_KEYNEXT()
Harbour alternative which has it.
; Some legacy PP functions are no more.
; hb_vmPushState()/hb_vmPopState() APIs were now permanently deleted.
; __STR*() token handling legacy functions are no more, use native HB_TOKEN*()
ones instead.
; WRITEBHEADER in USRRDD is no more, WRITEDBHEADER is the replacement.
; hbmysql, hbodbc compatibilty and deprecated functions were deleted
; hbwin compatibility functions were deleted. If there is demand, mainly to
help migrating xhb users, they can be readded to xhb lib by interested
developers, now deleted code should be changed to fall back to dummies
on non-Windows builds.
; some deprecated hbpgsql functions were deleted
; hbtip HB_BASE64() is deleted. Use core HB_BASE64ENCODE() instead.
; Anyone affected by above changes has the option to stick with 3.0.x Harbour
versions or to update their source code according to above instructions
(or instructions included in past ChangeLog entries)
; Some fallouts in Harbour build is possible after these changes
* src/vm/thread.c
* upped sleep timeout in *nix version of hb_threadReleaseCPU() to 20 ms
it halves CPU consumption. pls revert/comment if you notice
causing this any harm.
* harbour/src/vm/thread.c
* set sleep timeout in *nix version of hb_threadReleaseCPU() to 10 ms
* harbour/src/compiler/hbpcode.c
! fixed typo which could cause compile time crash when debugger code
is generated (-b) and file name with extenssion has only one or
two characters
* harbour/include/hbcompdf.h
* harbour/src/compiler/hbmain.c
* harbour/src/compiler/hbstripl.c
* harbour/src/compiler/harbour.y
* harbour/src/compiler/harbour.yyc
! removed old code designed to optimize line numbers generated in PCODE.
It cannot work correctly and in some cases it was generating HB_P_LINE
pcodes in wrong places.
% enabled new code for HB_P_LINE PCODEs optimization also in debugger (-b)
compilation so it can be used to replaced the old one.
* include/harbour.hbx
* src/vm/runner.c
+ HB_HRBGETFUNLIST() -> <aArray>: New function posted to the
list by Francesco Saverio Giudice
(NOTE: I changed the name a little bit)
* tests/gfx.prg
! fixed console output. Patch by Tamas Tevesz
* changed rest of ? commands to outstd()
* src/vm/set.c
* _SET_EOF default set to .T. on *nix to match other plaforms
(and Clipper I might guess)
CHECKME!
* formatting
! missing 'break;'. it didn't cause error, anyhow pls check me
maybe it was intentional (in 'case HB_SET_PRN_CON:' branch)
CHECKME!
* contrib/hbunix/hbunix.hbp
* contrib/hbunix/hbunix.hbx
+ POSIX_SLEEP( <n> ) -> <n>
* contrib/hbcurl/hbcurl.ch
* contrib/hbcurl/core.c
+ added changes from latest libcurl version (untested with
latest version)
* utils/hbmk2/hbmk2.prg
! fixed symbol names in hbx generation for watcom/{linux|dos|os2}
* harbour/include/hbapi.h
* harbour/src/vm/hashes.c
+ add new public C function: HB_BOOL hb_hashClear( PHB_ITEM pHash )
* do not generate RTE when unexisting key is passed to HB_HDEL()
now code which makes sth like:
if xKey $ hValue
hb_hDel( hValue, xKey )
endif
can be reduced to:
hb_hDel( hValue, xKey )
* harbour/src/vm/hashfunc.c
+ added new PRG function: HB_HCLEAR( <hValue> ) -> <hValue>
* harbour/src/vm/hashes.c
! fixed HB_HMERGE() to work correctly when destination and source hash arrays
are the same
! fixed HB_HASH_INTERSECT in HB_HMERGE()
% two minor optimizations
* harbour/src/vm/procaddr.c
! removed dummy entry at the end of function table
* harbour/src/common/hbstr.c
* harbour/src/rdd/dbfcdx/dbfcdx1.c
* harbour/src/rdd/hsx/hsx.c
* harbour/contrib/xhb/fparse.c
* pacified warnings
* harbour/include/hbsetup.h
* disabled flatten function attribute in ANDROID builds,
it causes that Android_NDK-GCC GPFs compiling src/vm/procaddr.c
* harbour/include/hbdate.h
* enabled localtime_r() in Android builds
* harbour/src/common/hbgete.c
* enabled setenv() in Android builds
* harbour/src/common/hbtrace.c
! fixed ANDROID_LOG_* flags
; QUESTION: why Android log is used instead of syslog?
It causes that harbour has to be linked with
log library (-llog).
* harbour/src/common/hbprintf.c
* disabled modfl() in Android builds
* harbour/src/rtl/filesys.c
* added hack for missing functions in android libc library
* harbour/src/rtl/diskspac.c
* harbour/src/rtl/disksphb.c
* use statfs instead of statvfs in Android builds
* harbour/contrib/hbct/dattime3.c
* disabled stime() in Android builds
* harbour/contrib/hbmzip/3rd/minizip/ioapi.h
* do not use 64bit FILE functions in Android builds
* harbour/contrib/xhb/hbsyslog.c
* disabled using Android log in Android builds - use standard syslog
instead. This code needs deeper modification to switch to Android log.
; I have just recompiled whole Harbour code for android-3, android-5
and android-9 at ARM using standard Harbour Linux build files.
Android does not have pthread and rt libraries (they are merged
with android c library) so to avoid link errors I simply created
soft links from libpthread.a and librt.a to libc.a.
With this hack could use unmodified hbmk2 and linux .mk files.
BTW exporting HB_CPU="arm" was not enough to switch to cross build
in my x86@64 Linux machine so I had to export HB_HOST_BIN and set
HB_BUILD_3RDEXT="no"
* harbour/src/vm/thread.c
* renamed hb_criticalCode() to hb_mutexEval()
* harbour/src/rtl/cdpapi.c
* added HB_CODEPAGE_ANNOUNCE( UTF8 ) so user can use
REQUEST HB_CODEPAGE_UTF8
in PRG code.
* harbour/tests/big5_gen.prg
; added note about characters mapped to U+FFFD REPLACEMENT CHARACTER
in BIG5.TXT and iconv mapping for the same characters.
* harbour/src/vm/thread.c
+ added new function:
hb_criticalCode( <pMtx>, <bCode> | <@sFunc()> ) -> <xCodeResult>
it executes <bCode> or @sFunc() when <pMtx> is locked by this function.
! fixed hb_mutexQueueInfo() to not overwrite RTE subst value.
This function may only return .T. or generate RTE so the logical
return value is useless. I think that it should be removed and this
function should simply return NIL.
* updated syntax of PRG functions
* harbour/src/vm/hvm.c
* extended item references created by hb_vmPushItemRef() so they
can be used to create reference chain and detached in executed
PRG code. Such reference chain is cleanly break when original
reference item is removed from HVM stack.
* harbour/src/vm/itemapi.c
! fixed compilation in MT mode with some C compilers using
HB_STACK_TLS_PRELOAD
* updated also hb_itemParamStore() function to set NIL to item passed
by reference when is called with NULL pItem parameter.
* harbour/src/vm/itemapi.c
* set NIL to item passed by reference when hb_itemParamStoreForward()
or hb_itemParamStoreRelease() is called with NULL pItem parameter.
* harbour/contrib/hbnetio/netiosrv.c
! fixed possible memory leak when
NETIO_SRVSTATUS( ..., NETIO_SRVINFO_PEERADDRESS, ... )
is called without 3-rd parameter passed by reference
* harbour/examples/gtwvw/gtwvw.c
* replaced repeated TONE code with hb_gt_winapi_tone()
+ added MOUSE_GETPOS() method
* harbour/examples/gtwvw/wvwtbar.c
! fixed to compile with Harbour
* harbour/include/hbapi.h
* harbour/src/rtl/hbrandom.c
added new C functions which fills memory block with random values:
void hb_random_block( void * data, HB_SIZE len )
this function should be used with "good enough" random generator
so in the future it may be changed to use internally sth different
then rand().
* harbour/src/vm/thread.c
* pacified minor warning
