MySQL Bugs: #7283: Test failure: 'update' (using '--ps-protocol': server crash)

Bug #7283	Test failure: 'update' (using '--ps-protocol': server crash)
Submitted:	14 Dec 2004 17:02	Modified:	14 Jan 2005 19:03
Reporter:	Joerg Bruehe	Email Updates:
Status:	Closed	Impact on me:	None
Category:	MySQL Server	Severity:	S3 (Non-critical)
Version:	5.0.3-pre	OS:	Linux (Linux / Athlon)
Assigned to:	Ramil Kalimullin	CPU Architecture:	Any

Description:
Test 'update' fails for me in current 5.0, when I run the test suite with '--ps-protocol'.
In a standard run, this test passes.

This is a non-debug build: 'compile-pentium-max'.

Failure report:
=== cut ===
update                         [ fail ]

Errors are (from /M50/push-5.0/mysql-test/var/log/mysqltest-time) :
/M50/push-5.0/client/.libs/mysqltest: At line 11: unable to execute statement 'update t1 set a=a+10 where a > 34': Lost connection to MySQL server during query (mysql_stmt_errno=2013 returned=1)
(the last lines may be the most important ones)

Ending Tests
Shutting-down MySQL daemon

master not cooperating with mysqladmin, will try manual kill
./mysql-test-run: line 1289: kill: (10) - Kein passender Prozess gefunden
master refused to die. Sending SIGKILL
./mysql-test-run: line 1293: kill: (10) - Kein passender Prozess gefunden
Master shutdown finished
Slave shutdown finished
=== cut ===

I tried to get a backtrace, but may have hit the wrong target:

  Fix for bug #7223: information_schema: error in "views"

The error is older, as I got it already yesterday but did not yet report.

How to repeat:
Run the test suite with '--ps-protocol'.

Thank you for your bug report. This issue has been committed to our
source repository of that product and will be incorporated into the
next release.

If necessary, you can access the source repository and build the latest
available version, including the bugfix, yourself. More information

Additional info:

fixed in 5.0.3

I pulled again, re-built, and re-tested: The error is still present (same symptom, no change).

I checked the sources, and the changeset 1.1771 (re-numbered by BK) is included in my sources.

I cannot reproduce it any more, seems to have been corrected (there were corrections for the '--ps-protocol' case).
