Changed my_error() to print error messages, which come from arbitrary registered ranges of error messages. Messages can be unregistered (and should be at end of the program). Added registration of handler error messages. Added a new mi_print_error() macro and a new mi_report_error() function, which supply error messages with a table name. Added calls to mi_print_error() or mi_report_error() at all places in MyISAM, where table corruption is detected.

SYNOPSIS
|
|
mi_report_error()
|
|
file_name Name of table file (e.g. index_file_name).
|
|
errcode Error number.
|
|
|
|
DESCRIPTION
|
|
This function supplies my_error() with a table name. Most error
|
|
messages need one. Since string arguments in error messages are limited
|
|
to 64 characters by convention, we ensure that in case of truncation,
|
|
that the end of the index file path is in the message. This contains
|
|
the most valuable information (the table name and the database name).
|
