* src/debug/dbgentry.c
! fixed typo in my previous commit for AltD() function detection
Thanks to Franček Prijatelj for reporting the problem and Abe
for self contain example
* src/rdd/dbfcdx/dbfcdx1.c
* reverted byte order in Harbour CDX signature - by mistake I used
little endian. When existsing index is open then reverted signatures
are accepted for backward compatiblity though they will be removed
in the future.
* src/rdd/workarea.c
* move results of EVALBLOCK() RDD method from Harbour stack return item
to workarea valResult item instead of copping it.
; Warning: This modification may exploit problems in code which
wrongly looks for result of EVALBLOCK() RDD method in
HVM stack return item instead of workarea valResult item.
* 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()
* 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
* 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
* src/debug/dbgbrwsr.prg
! fixed to not display last column out of browser area
* src/debug/dbghelp.prg
* src/debug/dbgmenu.prg
* src/debug/debugger.prg
* use strings to to locate help topics instead of hardcoded numeric
offsets
! added support for topic specification in "HELP" command - Cl*pper
compatibility
! allow to use FILE DOS (and F D shortcut) to activate OS Shell - Cl*pper
compatibility
* src/debug/dbgentry.c
! removed recent pseudo fix with memset() missing the last byte of
allocated memory area since e59993bdb1.
The original code was correct. In Harbour trailing 0 in all strings
is set inside functions creating string items.
* package/harbour.spec
+ added MXML library
* package/mpkg_rpm.sh
* respect HB_WITH_*=no and HB_WITH_*=local envvars
* src/debug/*
+ src/debug/en.txt
* sync with 4d61fc5a25/src/debug
* use DBS_* constants
! fixed to allow editing of CODEBLOCK types in hash/array/object elements
as it was allowed in single variables
! fixed to detect all workareas not just the first arbitrary 512
! fixed memset() missing the last byte of allocated memory area
since e59993bdb1
+ reworked help to store content in a text file out of the source code.
It reduces binary size, makes translation possible, editing easier,
source code leaner and easy to publish online.
! deleted help section explaining cld.exe
* formatting, cleanups, optimization, translatability
* extras/gtwvw/gtwvwd.c
! fixed typo in WVW_SETICON() - thanks to Ash
* src/rdd/dbcmd53.c
! typo in comment
* src/rtl/dateshb.c
% use hb_retclen() instead of hb_retc() when size is well known.
* src/rtl/valtoexp.prg
% use hb_defaultValue()
* src/vm/estack.c
* minor cleanup
* src/vm/fm.c
* modified a little bit HB_MEMINFO structure to force strict alignment
+ added debug code covered by HB_FM_FORCE_REALLOC macro which forces
allocateing new block in each hb_xrealloc() call
! protect realloc() in HB_FM_STATISTIC by mutex, it fixes issue #77.
* src/rtl/hbproces.c
% unlock HVM waiting for process in OS2 builds
! build array of argument passed to process in hb_processRun() in
parent process not forked one. It fixes possible deadlock in forked
process because memory is allocated to create arguments array and
in MT program memory managers may use mutexes internally which can
be cloned to forked process in locked state.
It fixes seldom and random HBMK2 freezing during compilation
with -jobs=<n> parameter.
* utils/hbmk2/hbmk2.prg
! fixed race condition in concurrent C compiler execution (-jobs=<n>)
with script file
* src/debug/dbgentry.c
! fixed crash when wrong expression is used as tracepoint
! fixed expression analyzer to correctly recognized extended strings e"..."
* formatting
* src/debug/dbgbrwsr.prg

* src/debug/dbgtmenu.prg
* src/debug/dbgtobj.prg
* src/debug/dbgtwin.prg
* src/debug/dbgwa.prg
* src/debug/debugger.prg
* added calls to ::NotSupported() method for some still missing
functionality
! do not use SetColor() but directly pass colors to used objects
and functions
! do not use SetPos() and Row()/Col() for core functionality - it was
source of few minor bugs
% enable cursor only in input objects and disable it just after
% eliminated code to save and restore cursor position and shape
! fixed initial positioning in help window
+ implemented HiLite() and DeHiLite() methods in HBDbBrowser() class
! fixed positioning when end of source data is reached in browser
% eliminated some redundant or completely useless code and comments
% use some fully functional HBDbBrowser() features instead of manual
encoding similar functionality
! validate watchpoint and tracepoint expressions
% use SWITCH statements
! fixed expression presentation (added __dbgValToExp() and __dbgValToStr())
! fixed input for new expressions
! fixed browser scrolling in object inspector
! fixed inkey() processing inside debugger (ALT+D and ALT+C)
! fixed browsers highliting in WA inspector
! fixed hardcoded limit for 512 workareas in WA inspector
! fixed initial WA positioning in WA inspector
* resized WA inspector window
* many other minor fixes and improvements
* src/rtl/filebuf.c
! unlock HVM stack before locking local mutex and calling hb_fs*()
functions which also unlocks HVM. It fixes possible deadlock condition
when hb_gcAll( .T. ) is executed.
* include/hbapi.h
* src/vm/garbage.c
! changed mark function semantic.
Adding support for user defined mark function I created race condition
in MT GC code. It happens because blocks marked as deleted were not
scanned by GC mark code so their subitems where not accessible.
To fix it we have to change mark function semantic. Now mark function
can be executed also for blocks currently deleted. It means that GC
block destructor should clean references to just removed items and
subblocks. The best place to make it is clearing pointers to GC blocks
just after hb_itemRelease() or hb_gcRefFree().
It is save to clean the reference just before hb_itemRelease() or
hb_gcRefFree() but only for the single block passed to these functions.
It is not save to clear reference to more then one block and then
execute above functions.
+ check reference count after destructor execution for all blocks
not only arrays - warning it may exploit some wrong C code.
- removed not longer used hb_gcRefCheck() function.
* include/hbvm.h
* src/vm/hvm.c
+ added new internal function hb_vmLockForce()
! fixed to mark GC blocks with active threads
* src/vm/thread.c
* include/hbthread.h
% modified sync mutexes used by xBase++ signal class emulation
to not use item array internally
* updated mutex destructor to new GC mark semantic
! mark GT items if GT is bound with thread item
! fixed mutex notify/subscribe code to not change GC items
when HVM stack is unlocked
! use hb_vmLockForce() to eliminate potential deadlock
+ added new C function hb_threadEnterCriticalSectionGC().
It should be used instead of hb_threadEnterCriticalSection()
in code which manipulates GC items inside critical section.
It's slower but eliminates possible deadlock condition.
Please remember that remember that both functions cannot
be used for the same mutex. So if it's necessary to use
hb_threadEnterCriticalSectionGC() in one place then it
has to be used in all others when the same mutex is locked.
* src/vm/arrays.c
* src/vm/codebloc.c
* src/vm/hashes.c
* src/rtl/hbgtcore.c
* contrib/hbcurl/core.c
* contrib/hbexpat/core.c
* updated destructors to new GC mark semantic
* contrib/hbxpp/dllx.c
! fixed destructor for pointer item created by DllPrepareCall()
Now it respects reference counter.
; added note about real behavior of library handle destructor,
I haven't changed existing code behavior but maybe it should
be done.
* contrib/xhb/hbserv.c
* src/debug/dbgentry.c
* src/rdd/wacore.c
! fixed possible deadlocks by using hb_threadEnterCriticalSectionGC()
instead of hb_threadEnterCriticalSection().
* contrib/hbmemio/memio.c
! slightly modified hb_memfsDirectory() code to avoid race condition
without using hb_threadEnterCriticalSectionGC()
* src/vm/fm.c
% reduce the lock range in HB_FM_STAT builds
* src/rtl/hbsocket.c
! added missing HVM stack unlocking in hb_socketSelect() function
* src/rtl/gtxwc/gtxwc.c
! added few missing locks for version compiled with HB_XWC_XLIB_NEEDLOCKS
* src/rdd/dbtotal.prg
* allow to use symbols instead of codeblocks
* modified Harbour extension which uses ordKey() as default group
signature to work also without index. In such case all records
are summarized into single one.
; Most of above modifications were critical for stability of MT programs.
They should allow to activate GC in any place.
* src/debug/dbgentry.c
! added additional protection against recursive debugger activation.
It should fix problem reported by Rafa.
* src/rtl/fssize.c
* use explicit open attributes.
* src/rtl/copyfile.c
! reset error object between different RTE calls in __copyFile()
! copy file attributes only on *nix platforms.
In Cl*pper __copyFile() does not copy attributes so maybe also
in *nixes we should make the same.
* contrib/xhb/xhbcopyf.c
* changed hb_fs*() API to hb_file*() API.
* src/debug/dbgentry.c
+ added protection against wrong parameters passed to __dbgDelBreak()
* src/debug/debugger.prg
+ implemented display history for command window.
This modification also fixes clearing command window when focus is
changed.
+ added support for new commands:
DELETE ALL BP
DELETE BP <nNumber>
LIST BP
* replicated Clipper compatible command line shortcuts
! send :RefreshAll instead of :RefreshCurrent to source code window
when break point changed
; TODO: add support for window resizing and repositioning. Commands
like LIST BP are in practice unusable in 3 line command window.
* src/rtl/console.c
% minor optimization
* src/debug/dbgentry.c
! added missing casting
* src/debug/debugger.prg
+ show in call stack references to code compiled without debug info
* src/rtl/itemseri.c
* ignore HB_HASH_RESORT flag during hash serialization
* src/debug/dbgentry.c
+ added new PRG functions:
__dbgIsBreak( <pDbg>, <cModule>, <nLine> ) -> <nPos>
__dbgGetBreakPoints( <pDbg> ) -> <aBreakPoints>
* src/debug/debugger.prg
- removed old and long time unused PRG function __dbgAltDEntry()
* src/rtl/hbproces.c
* changed returned status when execvp() fails, -1 should give
maximal exit code on given platform (i.e. 255)
* include/hbapidbg.h
* src/debug/dbgentry.c
* src/debug/debugger.prg
+ added new C function hb_dbgGetModuleName() - it returns module name
used to register module in HVM. In current version it only strips
path part though in the future it may use some more advanced code
which allow to debug modules with the same name but different paths
in single application and such extension will be local to core debug
code if upper level debugger uses hb_dbgGetModuleName()
+ added new PRG function __DBGGETMODULENAME() - it's wrapper to
hb_dbgGetModuleName()
+ added new PRG function __DBGMODULEMATCH()
! use __DBGMODULEMATCH() instead of hb_FileMatch() and strip_path()
! eliminated strip_path() from PRG code and use hb_dbgGetModuleName()
in C code in places where it's necessary
! replaced few strcmp() used to compare module names with
FILENAME_EQUAL()
; above modification may fix few potential problem with breakpoints
in debugger on some platforms if user uses different paths for
debugger and compilers.
! eliminated hack with memvar/field name copy in watch points,
it also fixes memory leak when fields are used in watch points.
% replaced few DO CASE with SWITCH
* (all files)
* stripped svn header
* minor cleanups
; use following command to find out the history of files:
