* config/global.mk
* set HARBOUR=F:100 during build process in OS2 builds - it increases
maximum number of open handles per process from 20 to 100 so it should
be possible to use -j<n> switch during Harbour compilation - please
test, i.e.:
os2-make -j3
* contrib/xhb/hbcompat.ch
! fixed pp rules for Str(,,, <lStrip> ) translation
* include/hbapifs.h
* src/rtl/filesys.c
+ added new C function:
HB_FHANDLE hb_fsOpenEx( const char * pszFileName, HB_FATTR nAttr,
HB_USHORT uiFlags );
* minor cleanup
* include/hbmemory.ch
* src/vm/fm.c
+ added two new actions for Memory() function:
HB_MEM_STATISTICS - return non 0 value if FM statistic is enabled
HB_MEM_ISLIMIT - return non 0 value if used memory limit is
supported
+ added new PRG function:
__fm_allocLimit( [ <nNewLimit> ] ) -> <nPrevLimit>
It allows to set limit for maximum used memory in some memory
managers, -1 means no limit.
Now it works with DLMALLOC and in ST mode it's limit for memory
allocated from system for whole application. In MT mode when
HB_FM_DLMT_ALLOC (default for DLMALLOC) is enabled it's limit for
single MSPACE (Harbour allocates 16 MSPACES and balance them
between threads to improve scalability) so it's rather per thread
limit. If memory statistic module is enabled during Harbour build
process then this limit works with any memory manager and defines
limit for total memory allocated by Harbour application regardles
of MT or ST mode.
* src/vm/hvm.c
* use HB_MEM_STATISTICS instead of HB_MEM_USEDMAX to check if memory
statistic module is enabled
