RE: [GD-General] runtime error logging

[Tom F. <to...@mu...>]

We do three things. (1) surround high-frequency info with single quotes. (2)
hash the characters _not_ in single quotes. (3) check hash against a list of
"I've already reported that" errors. So you have:

LOG_ERROR ( "Unknown effect '%s' in mesh '%s'\n", sEffectName, sMeshName );

So this is a spritnf-style format string, and will come out to be something
like:

Unknown effect 'WATRE' in mesh 'blah.x'
Unknown effect 'WATRE' in mesh 'blah2.x'
Unknown effect 'WATRE' in mesh 'blah3.x'

...so then we remove everything in single quotes:

Unknown effect  in mesh 
Unknown effect  in mesh 
Unknown effect  in mesh 

...and hash those. And of course they all come out with the same hash value
and only the first one gets reported if you click on "Ignore all" in our
little dialog box.

RE: [GD-General] runtime error logging

[Gareth L. <GL...@cl...>]

Silly questoin, but couldn't you hash the string before the params were
evaluated ? So you would just hash "Unknown effect '%s' in mesh '%s'\n"

RE: [GD-General] runtime error logging

[Paul B. <pa...@mi...>]

I'm guessing that Tom wants to be able to shut off instances
of a log message (for a 'mesh1' but not 'mesh2').  I think
someone mentioned already that you hash the format string
for the "class" of logs and the formatted string for the
"instance" of logs. =20

I'm not sure why you would hash only the strings in quotes.
If you have multiple classes of messages that each used
'mesh1' as the only param then you'd potentially ignore
both by just hashing the params.

RE: [GD-General] runtime error logging

[Tom F. <to...@mu...>]

The reason is lost in the mists of time, but I think it was so you could do
obscure things like:

if ( type == TYPEA )
{
	ERROR ( "Error in thingie of type 'A'" );
}
else if ( type == TYPEB )
{
	ERROR ( "Error in thingie of type 'B'" );
}

...though actually you could have changed those to:

ERROR ( "Error in thingie of type %s", "A" );
ERROR ( "Error in thingie of type %s", "B" );


Oh, there probably was a good reason for it, many years ago :-)

Re: [GD-General] runtime error logging

[Julien K. <ma...@ju...>]

You could take the __FILE__ and __LINE__ preprocessor definitions as source
for your hash-function.. (jsut an idea.. never needed something like this).

Re: [GD-General] runtime error logging

[Andras B. <bn...@ma...>]

Hashing seems to be the best idea so far, so I think I'll stick with it.

thanks,
