Re: Case sensitivity in CLASSIFY and LEARN

   From: "Ger Hobbelt" <[email protected]>

   Actually, I say this is a bug in crm114 you've run into.

   <nitty gritty 'C' code detail mode on>
   The different behaviour with/without trap makes sense in a way, as the
   error was marked as trappable in the code, yet when caught by a trap
   that 'fatalerror5/fatalerror() call will 'return' so the script
   execution can continue and actually execute your trap handling script
   section -- where the next bit of code will exit crm114 ANYHOW, so no
   dice getting that trap section to actually run. And when you did NOT
   specify a trap, fatalerror() would already have 'exit()'ed the
   building, so you only see anything happening past that call when it IS
   trapped. Both ways, you're dead in the water.

   What's the bug then? Well, say fatalerror() found the 'trap' in your
   script and hence returns to caller so we can go on with our script
   (trap section), we STILL don't get a chance as right there in
   crm_set_temp_nvar() the code STILL exit()s the building, while it
   *should* have simply returned to caller.

   Meanwhile, this error IS 'trappable' (as it does not damage the system
   nor our state in unpredictable ways), just as that particular
   fatalerror() call would suggest (we have 'untrappableerror()' for
   those truely killing failures that are irrecoverable in any way), so
   the extra 'ha! you trapped me but, but nah nah, we exit crm114 right
   now anyhow' code bit has to go.

Hmmm... yeah, I think you are right... maybe.

The overflowing error is not retryable, but it is perhaps 
possible to maybe do something else.  however, if this was
a situation where you only had a couple of Kbytes left anyway,
then there may not be enough space for the TRAP handler to
run either.  I would need to check the TRAP source code on
this.

Also,  crm_expr_file_io.c should not ask for too many
characters either.  However, you can get to your patch
in other ways than through input of a very large file.

I'd put this in now, but my laptop is now deep in the throes
of Memtest86.  And it may need a reinstall.  :(
