NEW ITEMS:

IBISCHK710 development:
Mike LaBonte showed the user guide WIP 4 draft.  He said there was one message 6900 had no
message type or message text, and it had been omitted from the table.  Mike had to add
missing E, W, and C type codes for 3 or 4 dozen messages that had them as blank in the
spreadsheet.

Bob Ross asked about the issue of messages that could be issued as more than one type,
saying we had previously decided to list those once for each usage in the table.  Mike
showed an email on that topic, saying that there were at least 26 places in the code where
a message might be issued different ways.  In some cases the same message string might be
printed as either an error or warning.  In other cases the warning message would be
slightly different, usually with the word "suspicious" in it.  He said 3 utility functions
returned status codes of GOOD, BAD, or UGLY.  The UGLY return would signify either a
missing quote in a quoted string, or extra characters or digits in a number.  Those would
usually print warning or caution messages.  He recommended making no change to the tables,
saying it would take significant effort to catalog all such variant messages.  Bob agreed,
noting that we already had threshold-based variant messages.

We agreed to publish the user guide as reviewed.

AR: Mike LaBonte to upload IBISCHK User Guide and message spreadsheet


Parser bug reports:
Bob Ross said 4 new bug reports had been posted and would be classified Friday.  Michael
Mirmak said one of the new bugs on the web page had a curly bracket that needed to be a
square bracket.

Michael asked if we could add a description line to the bug template.  Bob said that would
not automatically propagate to the web page because the file bugdir.txt provided the
title, which he entered manually.  Bob said we could change the template, but he was not
sure if we should update old bug report files.  Mike LaBonte felt that was not necessary.

Michael said it would be good to have a web form that could be filled and submitted
online.  We agreed to ask the webmaster about that.  It might need a privacy notice and
reCAPTCHA verification.  Michael said we would want to support attaching files too.  Bob
was concerned that people would upload testcases that were not reduced.  Michael said a
file size limit might help.  Mike wondered if GitHub could be used.


IBIS quality checklist:

Tabled topics (no discussion without motion):
  - BIRD181.2
