Change History Since version 0.96 (otcl)

otcl-1.0a5 in progress

• [YP] Mon Jan 4 5:00:00 PST 1999
  BUG REPORT(NOT FIXED): validation test of autoload fails to pass under Linux and FreeBSD. Here is the upper part of the stack (Linux, which results in a segmentation fault):

      #0  0x4011378d in __libc_free (mem=0xbffed744) at malloc.c:2861
      #1  0x804a84b in AutoLoaderDP (cd=0xbffed744) at otcl.c:492
      #2  0x804aa35 in RemoveMethod (methods=0x80fc514, nm=0x8100920 "1", cd=0x80fc4c0) at otcl.c:571
      #3  0x804c9e0 in OTclCInstProcMethod (cd=0x80fc4c0, in=0x8099f90, argc=7, argv=0xbfff00f4) at otcl.c:1769
      #4  0x804a674 in OTclDispatch (cd=0x80fc4c0, in=0x8099f90, argc=5, argv=0xbfff0144) at otcl.c:421
      #5  0x804e523 in TclInvokeStringCommand ()
         

  This does not appear to be critical for ns, because it does not uses autoloading.
  

otcl-1.0a4 Released on Mon Feb 22 17:50:15 PST 1999

• [johnh] Thu Jul 23 10:26:54 PDT 1998
  tcl-7.6 support was broken; fixes inspired by Lloyd Wood should restore it.

otcl-1.0a3 Released on Tue July 7 13:10:00 PST 1998

• [johnh] Tue Jun 30 09:49:53 PDT 1998
  classinstvars support turned on by default (and the ifdef's removed).
• [johnh] Tue Jun 9 13:42:06 PDT 1998
  
  • Added support code for delayed binding (in tclcl). Currently this code is only turned on if you do --enable-tclcl-classinstvars when configuring.
  • re-autoconf'ed
  • condesed some of the tcl7/tcl8 compatibility code with #define ObjVarTablePtr
• [johnh] Thu May 21 21:49:34 PDT 1998
  
  • Fixed a case in OTclDispatch error handling where clobbered arguments (in the buggy callee) lead to a segfault.
• [johnh] Mon May 18 16:46:51 PDT 1998
  
  • install targets were backwards.
• [SM] Mon Dec 22 12:59:21 PST 1997
  
  • Fixed exactly the same bug as last rev. Only difference is it occurred in another place.
• [SM] Sun Dec 21 22:11:14 PST 1997
  
  • Fixed a bug in OTclDispatch that caused core dump when an error conditrion occured evaluating an instproc with more than 8 args.
• [TLT] Wed Dec 17 15:22:49 GMT-8:00 1997
  • Added additional stack trace info when there is an error in OTclDispatch. This gives "resolved_class procname ..." in addition to the "_o? procname" line.

otcl-1.0a1 Mon Dec 15 20:13:00 PST 1997

• [SM] Mon Dec 15 20:13:00 PST 1997
  
  • Converted configure to use mash/ns configure infratructure.
  • Cleaned up this change history.
  • Fixed things up for test release of 1.0a1 (need to clear with Wetherall, though he gave a preliminary "okay").
• [KVa] Mon Dec 8 09:51:16 PST 1997
  • Linux uses libdl.a (not libdld.a).
    Fix configure, configure.in.
• [TLT] Sat Nov 15 18:29:41 GMT-8:00 1997
  • changed makefile to compile functions with static library
  • changed otcl procedures to use a single "::otcl" namespace. This removes the need for the previous kludge in otcl, whereby a tcl procedure is created using TclProjCmd, and then deleted from the interpreter so that only otcl knows about it. For the deletion to work, we have to use a hack which increment the reference count before deleting it. Besides the high chance that this hack will not work with future versions of tcl, the deletion also invalidates the byte compilation and as a result each proc is byte-compiled twice.

    In AddMethod(), procedures are now created as ::otcl::pn where n is a running number. The deleteproc of the created procedure (OTclDeleteProc) now uses Tcl_FindCommand() to delete the procedure from tcl if it still exists.

    Some simple experiments show that the impact on speed and memory is small.

• [EA] Tue Oct 28 11:50:08 PST 1997
  
  • Fixed problem in ListProcArgs since tcl8 now appends instvars and arguments to ame list, but adds a flag.
• [TLT] Sat Oct 25 19:49:19 PDT 1997
  
  • fix problem where some variables are freed multiple times. The variable flags is a bitmap now, so that (vp->flags != VAR_UNDEFINED) is not correct.
• [TLT] Mon Oct 6 14:46:51 PDT 1997
  
  • Merged in patch for Tcl/Tk8.0 from http://catarina.usc.edu/~haoboy/otcl-0.96.patch.
  • (Bug fix) PrimitiveCDestory attempts to delete the instances hash table after its contents have been free in PrimitiveODestory. Created new function PrimitiveODestoryNoFree that does not free the memory itself.
  • (Bug fix) MakeProc creates a new procedure, then calls Tcl_DeleteCommand with a null deleteproc to create a Tcl-invisible proc. With 8.0, Tcl_DeleteCommand frees the cmdPtr structure also, which renders the "invisible proc" unusable. Added code to prevent the deletion of cmdPtr and free it up when the procedure is destoryed.
    Check that this kludge works when we move to a new version!
• [TLT] Thu Aug 7 13:26:18 PDT 1997
  Checkin of makefile.vc for win32. otcl.lib and tclsh.exe now compiles under WinNT 4.0. It should run/compile on win95 as well (not tested yet).
• [TLT] July 97 Merged in changes from Steve Mccanne to fix the bug that causes tcl to remove and free some instvars twice.
