Hello all, I have troubles with backport some errors from 5.5 to 5.1 http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html#sysvar_… http://dev.mysql.com/doc/refman/5.5/en/error-messages-server.html#error_er_… Last error in mysql 5.1.49 - 1640. If i just add ER_QUERY_CACHE_DISABLED --- a/sql/share/errmsg.txt 2010-07-09 16:35:08.000000000 +0400 +++ b/sql/share/errmsg.txt 2010-07-31 20:41:47.244015659 +0400 @@ -6213,3 +6213,7 @@ ER_DEBUG_SYNC_HIT_LIMIT eng "debug sync point hit limit reached" ger "Debug Sync Point Hit Limit erreicht" + +ER_QUERY_CACHE_DISABLED + eng "Query cache is disabled; restart the server with query_cache_type=1 to enable it" + then error code of ER_DEBUG_SYNC_HIT_LIMIT is 1641 (instead of 1651 what i need). If i try: --- a/sql/share/errmsg.txt 2010-07-09 16:35:08.000000000 +0400 +++ b/sql/share/errmsg.txt 2010-07-31 20:41:47.244015659 +0400 @@ -6213,3 +6213,8 @@ ER_DEBUG_SYNC_HIT_LIMIT eng "debug sync point hit limit reached" ger "Debug Sync Point Hit Limit erreicht" + +start-error-number 1010 +ER_QUERY_CACHE_DISABLED + eng "Query cache is disabled; restart the server with query_cache_type=1 to enable it" + then mysql doesn't start with error in bootstrap.log like: "mysqld can't srart because errmsg.sys has only 642 errors, when last error number is ...." How can i backport error from mysql 5.5 to mysql 5.1 right? Now i solve trouble like: --- a/sql/share/errmsg.txt 2010-07-09 16:35:08.000000000 +0400 +++ b/sql/share/errmsg.txt 2010-07-31 20:41:47.244015659 +0400 @@ -6213,3 +6213,27 @@ ER_DEBUG_SYNC_HIT_LIMIT eng "debug sync point hit limit reached" ger "Debug Sync Point Hit Limit erreicht" + +ER_QUERY_CACHE_DISABLED_WRITE_SPACE_01 + eng "Fix error number for ER_QUERY_CACHE_DISABLED" +ER_QUERY_CACHE_DISABLED_WRITE_SPACE_02 + eng "Fix error number for ER_QUERY_CACHE_DISABLED" +ER_QUERY_CACHE_DISABLED_WRITE_SPACE_03 + eng "Fix error number for ER_QUERY_CACHE_DISABLED" +ER_QUERY_CACHE_DISABLED_WRITE_SPACE_04 + eng "Fix error number for ER_QUERY_CACHE_DISABLED" +ER_QUERY_CACHE_DISABLED_WRITE_SPACE_05 + eng "Fix error number for ER_QUERY_CACHE_DISABLED" +ER_QUERY_CACHE_DISABLED_WRITE_SPACE_06 + eng "Fix error number for ER_QUERY_CACHE_DISABLED" +ER_QUERY_CACHE_DISABLED_WRITE_SPACE_07 + eng "Fix error number for ER_QUERY_CACHE_DISABLED" +ER_QUERY_CACHE_DISABLED_WRITE_SPACE_08 + eng "Fix error number for ER_QUERY_CACHE_DISABLED" +ER_QUERY_CACHE_DISABLED_WRITE_SPACE_09 + eng "Fix error number for ER_QUERY_CACHE_DISABLED" +ER_QUERY_CACHE_DISABLED_WRITE_SPACE_10 + eng "Fix error number for ER_QUERY_CACHE_DISABLED" +ER_QUERY_CACHE_DISABLED + eng "Query cache is disabled; restart the server with query_cache_type=1 to enable it" + But this is ugly hack. What do you think about my trouble and ways for solve? Best regards, Oleg.

[Maria-discuss] Possible CVE from upstream
by Brian Evans 29 Jul '10

29 Jul '10

This seems to affect the released versions of MariaDB as well since they are based on 5.1.47 upstream as far as I can tell. CVE-2010-2008 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-2008) MySQL before 5.1.48 allows remote authenticated users with alter database privileges to cause a denial of service (server crash and database loss) via an ALTER DATABASE command with a #mysql50# string followed by a . (dot), .. (dot dot), ../ (dot dot slash) or similar sequence, and an UPGRADE DATA DIRECTORY NAME command, which causes MySQL to move certain directories to the server data directory.

[Maria-discuss] where are the buildbot results for valgrind and the InnoDB plugin?
by MARK CALLAGHAN 25 Jul '10

As described in http://mysqlha.blogspot.com/2010/07/building-mariadb-with-innodb-plugin.html I did some of the QA checks that I do for any new code that I might use. I have yet to find buildbot results for valgrind and the InnoDB plugin or XtraDB. Are they not run for buildbot? -- Mark Callaghan mdcallag(a)gmail.com
