Possibility to break DRAW commands by user break (Control-C) is implemented as follows:
- Treatment of Control-C (SIGINT signal) on UNIX in OSD::SetSignal() is made coherent with Windows implementation: instead of attempt to raise exception (simulated by longjump, does not work anyway), signal handler just sets a flag which can be later checked by OSD::ControlBreak()
- Call to OSD::ControlBreak() is added to common entry point for OCCT DRAW commands; this causes command interruption if Control-C has been pressed before its start.
- Command "dbreak" added allowing to check Control-Break status from Tcl script (raises Tcl exception if break was signaled)
- Command "dversion" added printing information on OCCT version, used build options, compiler, etc.
- Test system modified to properly handle and report user breaks and add version info in the summary log
Fix compiler error on Linux
Two commands are added in DRAW:
decho: allows switch on/off echo of commands and their results. When echo is on, all commands implemented as OCCT DRAW C procedures will be echoed to standard output, along with their result. This can be useful to trace process of execution of script evaluated by 'source' command.
dlog: implements off-screen log for recording DRAW commands and their output for further processing in Tcl script (mainly for use in automatic tests). Run this command without arguments to get help.
Added ios::sync_with_stdio() call to Draw::BasicCommands.
