2.- UDFs are still created by sys_flag being NULL, so show_functions() should acknowledge that fact.
3.- Implement naive code to show an approximate script-related line number when a failure happens. (Unlike my private FB1's isql, it doesn't rely on strings subject to localization.)
4.- With SET PLANONLY ON, PLAN was activated, but with SET PLAN OFF, PLANONLY wasn't deactivated.
5.- Include isc_info_sql_stmt_get_segment among statements that are like SELECT.
6.- Solve a bad interaction between PLANONLY and SQLDA_DISPLAY, where the first being activated didn't allow to see the output XSQLDA.
7.- More error detection.
2.- ISQL_get_index_segments shouldn't overflow in extreme cases. Better print an indication that the extraction wasn't completed (ellipsis).
3.- Fix bug with EXTRACT_list table that was printing ); if it didn't find the required table. This in turn caused bugs in other functions.
4.- STDERROUT is used in all places with second argument set to true. Simplify it.
5.- Delete the code previously commented for WAL.
6.- Fix add_row and copy_table. These features were requested to be made available in release mode at v1 time by Paul Beach. They should now be able to cope with quoted identifiers, too.
7.- Complement usage of readNextInputLine when called directly to avoid reading garbage or causing memory errors.
8.- Fix several strings that should have been declared with MAXPATHLEN since the first moment.
9.- Misc bug fixes and B.O. closed.
- obsolete items like WAL and JOURNAL (cleaned in the past)
- crud from attempts never finished like the shared cache manager for Classic
- DSQL nodes that aren't used. This allowed freeing some keywords.
The functionality was disabled by commenting the code. No code has been deleted.
Fix isql bug #910430.
Add SET HEADING ON/OFF option
Add -M2 command-line option to send output of statistics and plans to the same file than the rest of the output.
Those items do not appear when using HELP SET inside isql or with isql -? from the command line.
placed some variables in context
fixed some function signatures
closed a few possible buffer overruns
sorry to the platform maintainers, I can't verify what I did for non-Win32 builds
