Frank,
I've found the reason for the crash in the bug report, although I can't
explain why we are getting such different outcomes. The current
PHP_RSHUTDOWN_FUNCTION(mssql) is:
PHP_RSHUTDOWN_FUNCTION(mssql)
{
STR_FREE(MS_SQL_G(appname));
if (MS_SQL_G(server_message)) {
STR_FREE(MS_SQL_G(server_message));
}
return SUCCESS;
}
The string is free'd, but the MS_SQL_G(server_message) isn't properly
reset to empty_string. If I change this to:
PHP_RSHUTDOWN_FUNCTION(mssql)
{
STR_FREE(MS_SQL_G(appname));
if (MS_SQL_G(server_message)) {
STR_FREE(MS_SQL_G(server_message));
MS_SQL_G(server_message) = empty_string;
}
return SUCCESS;
}
then the crash goes away. (For consistancy sake the
"MS_SQL_G(server_message) = NULL;" on line 1315 should probably be
changed to "= empty_string" also.)
When I run the query in the bug report the call to mssql_query only
processes the first chunk of statements of the multi-statement query
and it holds on to the output of the rest of them. They remainder
don't actually end up getting processed until during the call to
dbclose() in _close_mssql_link. The output I end up seeing is:
Warning: mssql_query(): message: Cannot insert the value NULL into
column 'myFie
ld1', table 'myDB.dbo.myTable'; column does not allow nulls. INSERT
fails. (seve
rity 16) in c:\temp\test.php on line 30
Result is true
DB Error is The statement has been terminated.
Warning: Unknown(): message: Some error (severity 18) in Unknown on
line 0
Note that the "Some error" message comes after all the other output
lines and has no script location tied to it. I'm going to continue to
dig into this. Please let me know if you have any thoughts about where
I might look.
Michael
