Question about Server Debug Info
Hello List, On two different occasions and on two different servers I have found server debug information written out to the mysqld.log file. Now I know that by issuing the kill -1 mysql-pid will write that information to the mysqld.log file, and by using mysqladmin debug will also write debug information to the mysqld.log file. I am wondering what other methods would write the debug info to the mysqld.log file. On the two servers in question my fellow DBA's nor myself did nothing that would have written debug info. Are there any internal settings or processes that would write debug information to the mysqld.log file? Could a client tool do something like this? We have reviewed the app privileges and the they have no ability to write debug info.

Unresolved symbols with mysqlclient in DEBUG mode using VC++ 2010 Express
Hello friends I'm back to MySQL programming using the C API... it works fine when I compile using the RELEASE mode and C:\Program Files (x86)\MySQL\MySQL Server 5.5\lib but if I choose the DEBUG mode and C:\Program Files (x86)\MySQL\MySQL Server 5.5\lib\debug it fails at link time: 1mysqlclient.lib(dbug.obj) : error LNK2019: unresolved external symbol __CrtSetReportFile referenced in function _DbugExit 1mysqlclient.lib(my_init.obj) : error LNK2001: unresolved external symbol __CrtSetReportFile 1mysqlclient.lib(dbug.obj) : error LNK2019: unresolved external symbol __CrtSetReportMode referenced in function _DbugExit 1mysqlclient.lib(my_init.obj) : error LNK2001: unresolved external symbol __CrtSetReportMode 1mysqlclient.lib(my_init.obj) : error LNK2019: unresolved external symbol __CrtDumpMemoryLeaks referenced in function _my_end 1mysqlclient.lib(my_init.obj) : error LNK2019: unresolved external symbol __CrtCheckMemory referenced in function _my_end I read some posts that found in google about this error and found that it should be used the dynamic library libmysql instead of the static mysqlclient when debugging, but the lib\debug directory contains just the static library mysqlclient... Do I have to include an aditional library so the symbols are resolved correctly? The release mode works perfect and the application runs fine in that way only...

Re: Unresolved symbols with mysqlclient in DEBUG mode using VC++ 2010 Express
Hello Lars After hours of testing different project configurations, finally I was able to compile with debug mode... still pending the test of debugging, but just created the DLL (it was a library that I'm developing) without errors... The configurations I used (VC++ 2010 Express) were: RELEASE: - Runtime: /MT (static threaded) - Library: mysqlclient.lib (...\mysql\lib) - Ignore library: LIBCMTD.lib (without this does not link the release) - Debug: NO RELEASE: - Runtime: /MTd (static threaded debug) - Library: mysqlclient.lib (...\mysql\lib\debug) - Ignore library: empty (now allowed LIBCMTD.lib or does not link the debug) - Debug: YES If I try to use /MD or /MDd does not compile, if it works with /MT(d) will leave it that way XD I'm going to test the debug version (one thing is that compiled and another one that works =) and if get stuck again will post it... Thanks for your response P.D. One last question, is it right to use ...\mysql\lib\debug directory for debug version? or it should be set to ...\mysql\lib in both cases and the linker chooses the right one? If compiling in debug mode it works with both ...\mysql\lib and ...\mysql\lib\debug in DEBUG mode... maybe running the debugger will not work with the lib, still have to test, but at least it compiles with no errors... can you comment something about this?

In general, you'd want to ensure every object file and static library linked into your program is compiled with the same runtime library selected /MT[d] or /MD[d], to ensure a proper working environment. If you were to link with libmysql.lib you'd avoid having to match up these flags for this particular library for your own code. Mixing and matching these flags among things linked into a executable or dll is a recipe for a headache on Windows. Regarding your question about the directory, you'd more than likely want to link with the one in the debug directory, I think, to get useful stack traces into library code when debugging.

Perhaps there must be a PHP/DB that I can load... and run a stress test like you would test network issues with speedtest.net just a thought.. I know you dont compare apples to oranges. MySQL databases can be slow for any number of reasons. When I need to attack a performance problem I look for bottlenecks in 4 physical components of the server: CPU, RAM, DISK, NETWORK. If any of those places are overloaded, I then examine the configurable components of MySQL to see how I can reduce/eliminate that overload. Here are the big things I look at: * Table design - Is the data being stored efficiently? Is it properly indexed? * Query design - Is this query written efficiently? Can it use any indexes that are already on the tables? Does it retrieve only the rows and columns that the user actually needs or is it moving a lot of extra data for no good reason? Does it use batch-oriented logic and not procedural SQL? * Server configuration - Is the server configured to remain within the RAM limits of the machine? Are the buffers allocated appropriately for the usage patterns of the storage engines? Can we reduce any hardware contention through setting changes? * Usage patterns - This is not really a server configuration but it *is* the leading cause of slow performance. There are usually many ways to write the same query or to perform the same action. The MySQL server will do exactly what you tell it to do, even if that means performing billions or trillions of comparisons to answer a single query. One very slow (or very greedy) query has the ability to interfere with every other fast query on the machine at that time giving them all the appearance of being slow. Concentrate on the worst offenders, because your problem may be in your USER not the machine. So, you already know that your CPU tops out (99%) when you issue a certain query. This means your query is either doing a lot of computation or a lot of memory manipulation. Look at your query and think to yourself, How would I answer that query if I were the server. Use the EXPLAIN command to show you which indexes, if any, will be used for the query and how many rows it is pulling from each of the source tables. Multiply those row numbers together to get an estimate of how many comparisions the query is trying to compute for you. And finally, know the MySQL manual. It is your best source of information when it comes to understanding or interpreting the information you can collect. I think a nice place to start will be here: http://dev.mysql.com/doc/refman/5.0/en/optimization.html Warmest regards, -- Shawn Green, MySQL Senior Support Engineer Sun Microsystems, Inc.

Are you sure that VS2008 support Mysql6.0, since mysql 6 is in alpha stage. -- Sharique On 1/10/09, Miguel Cardenas renit...@gmail.com wrote: Hello list I have a problem debugging a program that uses MySQL.

Re: mysqld, mysqld-nt, mysqld-debug
Varuna, A polite note - if you post the same question 6 times (especially in the space of 24 hours) people are going to be more unlikely to help you. Post the question once, and read people's responses. Now onto your issues... When you run mysqld-nt you were starting a standalone version of MySQL with named pipes support. Once this was running in one command window, you would need another command window with a client connecting to that server. The message you are getting back from Windows is that mysqld doesn't exist in C:\Program Files\MySQL\MySQL Server 5.0\bin. My first step would be to do a search for this binary (Start Search Files or Folders etc.) Secondly there are a number of ways in which MySQL can be installed on a Windows system - how did you do it? Which package did you download? Have you run the configuration wizard? (I don't use MySQL on Windows so I'm reading from the manual.) Have you installed MySQL as a service or as a server? If you've installed as a service, then you shouldn't need to be starting the server manually - just stop and start the service using services.msc. If not, I'd highly recommend reinstalling and doing so. As for users, if you've not assigned the user a password when you created it, that user won't have a password so you don't need the -p option in MySQL client programs. If you haven't created a user, the only user your system will have configured is root.

Varuna, Please also remember to copy the list back in to your response so others can follow your steps if they're having trouble.

Re: Problem using debug switch with mysqlimport
Hello. Check that your MySQL installation was compiled with debug support: mysqld --help If the --debug flag is listed with the options then you have debugging enabled. mysqladmin ver also lists the mysqld version as mysql ... --debug in this case. I'm trying to utilize the debug switch with mysqlimport so that I can figure out why I'm getting errors on the data I'm importing, but I have yet to figure out a way to do this. I've tried to read the sparse documentation concerning this feature and no debug file is ever produced. I've tried using it as indicated by the mysqlimport --help documentation such as: /usr/local/mysql/bin/mysqlimport --debug=d:t:o,mysql.dbg -uuser -ppassword --local database import_file As well as many variations of this. I've been unable to locate through Google or anything else anyone who has successfully utilized this feature. Does anyone out there have any input? Thanks.

Help with --with-debug
Hello This is probably real simple for someone that knows - I'm having a few problems installing MySQL on a particular server (it's repairing a damaged copy). I'd like to try and fix it myself so I'm recompiling with the --with-debug option. If I manage to fix the problem, is there any overhead of having MySQL built with --with-debug? Or should I eventually recompile without --with-debug when the server is put into production?

MySQL compiletime errors with --with-debug=full
Hello, I am trying to report a bug, and I would like to compile mysql with debugging enabled to provide further information, but I receive compile errors. I would like to resolve the compile errors before I report the possible bug I have discovered. I am running FreeBSD 4.8, and I attempt to compile mysql-4.0.13 with the following configure command: ./configure --with-vio --with-openssl --with-debug=full (the initial bug I wanted to report is related to openssl so compiling with the ssl and vio options is essential). I then try running 'make' but I get a lot of undefined reference errors - so I have piped the STDOUT and STDERR to a file available for download at: http://www.no1.com.au/~adamc/makeoutput.txt hoping that someone with more C/C++ knowledge than myself can offer some insight.

mysqlserver debug
Hi,
Does anyone succeed to run embedded mySQL application
(libmysqlserver) built in Debug. I got RtlHeapValidate exception on
any mysql calls which allocates and free some memory. Crash appears
in:
-- cut ---
void my_no_flags_free(gptr ptr)
{
DBUG_ENTER(my_free);
DBUG_PRINT(my,(ptr: %lx,ptr));
if (ptr)
free(ptr); !
DBUG_VOID_RETURN;
} /* my_free */
---
It's appears only in Debug mode, Release work fine.
Any ideas?

Invalid Argument ??? Not sure how to debug this
Hi all and Good Morning.
I have been struggling with this code: I was wondering if someone could
lend me a hand.
I am working with this code and can't get the error to disappear.
After running I get
|-|
| Warning: Supplied argument is not a valid MySQL result resource in C:\My
|Documents\My |
| Webs\php\TMPibtpit3zq0.php on line 12
| |
|-|
Line 12 happens to be the WHILE statement. I am not sure if it is the
while statement or the results its looking for.
TIA So far, i havent been able to sleep atleast until I get this.

Put in some error checking code when you use the mysql functions as per the manual examples and you'll soon find where the error is. -- Jason Wong - Gremlins Associates - www.gremlins.com.hk /* I'm having an emotional outburst!! */ - 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?

How about:
SELECT * FROM cd_list WHERE searchstring LIKE '%{$searchstring}%'
Then again, do you actually have a column called searchstring in your
table?
In any case, the way you had it didn't seem to make much sense unless you
wanted to search a user-supplied column for a string that literally
contained the string searchstring.

Where is Win32 binary NON-debug 3.23.39 ? Debug builds much slower ?
I'd rather not fire up Viz C just to build MySQL 3.23.39 NON-DEBUG. Is there much of a performance difference between DEBUG NON-DEBUG ? Also with the Windows binary builds how does one NOT use MySQL MAX, is that a runtime option or do you need a different build entirely ? Is there much of a performance difference between MAX regular MySQL ? - Sam. - Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo! Messenger http://phonecard.yahoo.com/
OUTFILE ownership under mysqld 3.23.36-debug
Ok, this is confusing me. Under FreeBSD 4.2 and MySQL 3.23.36-debug: The mysqld process is not running as root, but as 'mysqld:mysqld'. bmdb2# ps -orgid,ruid,command -eww -p 46884 RGID RUID COMMAND 6724 6724 MYSQL_TCP_PORT=3306 OLDPWD=/var/mysqld/db/mojo log_dir=/var/mysqld/log TMPDIR=/var/tmp PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin MYSQLD_DB=/var/mysqld/db UMASK=0644 DBI_HOST=localhost MYSQL_BASE_DIR=/usr/local PWD=/var/mysqld/supervise UMASK_DIR=0777 /usr/local/libexec/mysqld --language=/usr/local/share/mysql/english --port=3306 --pid-file=/var/mysqld/db/mysqld.pid --datadir=/var/mysqld/db --basedir=/var/mysqld/db/mysql --tmpdir=/var/tmp --exit-info --set-variable=max_connections=1000 --log-update=/var/mysqld/log/bmdb2 The 'RGID RUID' is the real (as opposed to 'effective') GID and UID of the process. Then there's the environment. Then the arguments to the server itself. (You may not that I'm not using /etc/my.cnf to configure the server; I prefer to see the arguments.) Also, the server was lauched outright as UID mysqld, so I'm not using '--user'. The user 'mysqld' has it's own group, and that's the only group it's in: bmdb2# id mysqld uid=6724(mysqld) gid=6724(mysqld) groups=6724(mysqld) Yet, somehow, an SQL command such as this: select username from user limit 5 into outfile '/var/tmp/mysqld/sample'; creates a file with the 'wheel' group: bmdb2# ls -ld /var/tmp/mysqld/sample -rw-rw-rw- 1 mysqld wheel 65 Apr 10 19:36 /var/tmp/mysqld/sample I have no idea how a non-root process can set a different group than it's own. I can't find any suid/sgid code in the installed MySQL code.

logging doesnt work with bdb if --with-debug
Description: oliver After several sig 11 I compliled a --with-debug version and enabled oliver debugging and logging. Mysqld crashed shortly after starting without oliver trace (!) and then immediatly crashed again after restart. oliver /sw/pkg/mysqldebug/3.23.36/libexec/mysqld: ready for connections oliver mysqld got signal 11; oliver The manual section 'Debugging a MySQL server' tells you how to use a oliver stack trace and/or the core file to produce a readable backtrace that may oliver help in finding out why mysqld died. oliver 010407 20:37:48 mysqld restarted oliver __db_assert: "( logp-dbentry[i].dblist)-tqh_first == ( dbp)" failed: file "../.././bdb/dist/../log/log_rec.c", line 433 oliver 010407 20:37:48 mysqld ended How-To-Repeat: oliver Compile mysql with --with-debug and --with-berkeley-db, use bdb tables oliver and run mysqld with --debug --log Fix: oliver Dont do that :/ Actually, the above problem has nothing to do with debugging. The problem is that you have got something bad in the BDB log files, which BDB because of some strange reason can't resolve. Fix: Remove all filed of type 'log.xxx' from the MySQL data directory and restart MySQL. If you get this problem again, then where is what you should try to do: - Dump all BDB tables to text files. - close down mysqld - Remove all log files of the above format - Move all BDB tables to some secure place (as a backup) - Restart mysqld - Read back the BDB tables. If you get a crash, make a copy of log files and the bdb tables and contact us; We will help you make a bug report that we can send to the Berkeley DB people to help sort this out; They are very dedicated in trying to find and fix any bugs in their recovery code.
