ns: Change History

v1.0a10 Fri Oct 27 17:44:39 PDT 1995

• Fixed test-suite.tcl so that old awk works. Problem reported by Kannan Varadhan.
• Fixed Makefile.in to use V_LIB_TCL, as intended. Fix supplied by Kannan Varadhan.

v1.0a9 Wed Oct 11 16:58:00 PDT 1995

• Fixed solaris compilation problems.
• Changed configure to use "-mv8 -msupersparc" only for gcc.

v1.0a8 Fri Sep 29 15:11:04 PDT 1995

• Fixed more for-stmt scope bugs.
• Fixed compilation problems with Sun and DEC compilers. Problem reported by Thierry Turletti.

v1.0a7 Wed Sep 27 19:55:23 PDT 1995

• First public (alpha) release.
• Included man page to FILES so it goes in tar.
• Updated README.

v1.0a6 Sep 21 09:24 PDT 1995

• Added "bug-fix" hook to tcp reno.
• Ported to tcl-7.4.
• Include Matt Mathis' test-all script.
• Changed "for" statement conventions to adhere to the proposed ANSI standard change which re-defines the lexical scope semantics of the initializer statement. In order to be compatible with both the old and new semantics, we have changed all instances of
  • for (int i = ... ) ...
  • use(i);
  to
  • int i;
  • for (i = ... ) ...
  • use(i);

v1.0a4

• Fixed bug in xgraph output: new version of xgraph doesn't understand FileorDev because it now uses the PRINTER environment variable. Bug fix from Matt Mathis (mathis@psc.edu).
• Added a 'test-all' sh script to distribution, which runs whole suite of regression tests and compares them against a reference output. Thanks to Matt Mathis (mathis@psc.edu).
• Don't include tk.h from Tcl.cc.

v1.0a1 Mon Jul 31 16:05:08 PDT 1995

• Changed all references to random() to use Random class so we can easily change our pseudo-random number generator.
• Added convention to object names so we can derive their type from their name.
• Changed nodes to be first class objects like rest of objects.
• Changed trace syntax to use tcl files rather than it's own open/close. For example,
  • set f1 [open out.hop w]
  • $trace attach $f1
• Changed '-' and 'd' trace records to have same format as '+' and 'h' trace records.
• Incoporate vic's "matcher" abstraction into agent and link models.
• Major hacking to port tcpsim to tcl framework.
