Hello All, I have continued to work on the MySQL multi-threaded issue but still no resolution. It works fine single-threaded (meaning setting the number of server threads to 1 in mira.conf). I am convinced it has nothing to do with using prepared statements. This leaves either MySQL is not being initialized properly for multi-threaded operation or there are improperly shared variables between threads. The MySQL initialization is fairly simple and since we link the thread-safe library, no different than than single-threaded operation except for the added check that MySQL is thread-safe (which it comes back positive). Each sever thread has its own instance of the DbMySqlDirectory (which is derived from DbDirectory) and each DbMySqlDirectory creates its own connection to the MySQL server so each thread has its own DB connection. The only shared variable is a first-time initialization flag which is controlled by an exclusive lock (in fact, the lock is not needed since this DbDirectory constructor is only currently called by main()). All other code uses local or instance-level variables. I have added extensive debug code to my local version of mira_server. It displays the beginning and ending of DbMySqlDirectory methods indicating thread ID and instance address. This gives me a view into what threads are active and what DbMySqlDirectory instance they are using. The scenario which constantly causes the server to crash is as follows: 3 users with 2 workplaces where each workplace has 2 members. Login of one user (sometimes it takes two logins). The server segfaults when DbMySqlDirectory.find_workplace(ID) is active with one thread and multiple DbMySqlDirectory.find_user(ID) are taking place. This is when the client has received information on one workplace the user belongs, issues commends to find out user details of all members of the workplace, and issues a command to get information on the second workplace the user belongs to. This results in one thread doing the find_workplace() and other threads doing find_user(). The crash happens on a mysql_stmt_execute() command which performs the actual query on the server. The stack is trashed so I don't get a stack trace. I suspect the bind variables used in the query are trashed either on the mira_server side or the MySQL server side (these bind variables contain pointer to where to put the resulting queried data). All queries involved are read-only (select). I am not sure what to do at this point. I am out of ideas on resolving this issue. I could convert DbMySqlDirectory to use non-prepared queries or to use the C++ MySQL connector and see if that makes a difference. Both would require a substantial amount of rework and testing. I would prefer trying the C++ connector. I am not convinced that either would solve the problem but I am willing to do it. I don't want to hold up the project any longer because of this issue. I propose that I fix some issues I found during my investigation and submit those to the dbBackend branch and we document that a MySQL-configured server must run with one client thread until I fix the problem. If anyone would like to help me on this issue that would be great. Thanks, John |

Hello all, I am still not able to get the MySQL directory to work multi-threaded. I have been working on this off and on that last month and several days the last few weeks with no luck. It seems to work fine single-threaded. I have verified each thread has its own DbMySqlDirectory each with a unique connection to the database. I have not received any responses from my post on the MySQL C API forum and the response on the #mysql IRC was "C and C++ are complicated". I do have some simple sample code from the MySQL community documentation that does run multi-threaded. Interesting the original code used locks to provide exclusive access to the MySQL database which sort-of removes most of the benefits of running MySQL multi-threaded. I removed the locks and it seems to work fine. However this sample code does not use prepared statements. I am not sure if that makes any difference. I thought I would relay my status on the DB Backend. If desired, I could check-in a version of the Directory that essentially serializes MySQL access even in multi-threaded environments to use until the multi-threading issue gets worked out. Getting the MySQL part of the Directory to properly work multi-threaded may take awhile. What do you think? Thanks, John |

Hello All,
Been quite swamped lately (days of grading Microsoft Word assignments :-( ) and just got back to this. The problem seems to be that CMake expects the Qt executables to be in your path and I assume Qt moved them from 4.5.3 (from the docs) to the current 4.7.4. On Ubuntu, the command I used to set the path in my .bashrc file is:
export PATH=${PATH}:/usr/local/Trolltech/Qt-4.7.4/bin
Once I did this and redid:
cmake ./
the client built and ran.
For what its worth,
John

Hi all, Sunday's meeting was attended by John, Shilpa, Zied and myself. A transcript of the meeting can be found here: http://miragroupware.org/wiki/doku.php/development/communication/archives/110918_meeting This meeting had a brief agenda, which can be found here: http://miragroupware.org/wiki/doku.php/development/communication/agendas/110918_meeting We spoke first about meeting times. Following the mailing list thread on the same topic, we have decided to hold the next meeting (on Sunday 2nd October) at 13:00 UTC. This is the time that proves most convenient for all of us. At least, John, Shilpa, Zied and I all said that the time was suitable on a Sunday. If you find that this time is inconvenient for you in the long-run, please reply to the other thread regarding meeting times with your own preferences and we will do our best to accommodate everyone in the future. John has made excellent progress with his MySQL and SQLite database interfaces for the Directory layer. He has stabliised the MySQL interface, and has moved code which is common to both interfaces up to DbDirectory (above DbSqliteDirectory and DbMySqlDirectory). He has also removed a lot of archaic, commented out code. Finally, as you will have seen on the mailing list, he has prepared detailed instructions on how to configure the Server to use a database backend to store Directory data. The blueprint for the database backend to the Directory layer that is found on the wiki is now out of date, because I prepared it many years ago. John intends to update it to correct the record structures detailed therein. John also mentioned that he would like to merge his branch into our main branch, trunk. Given that his code is feature-complete, it just needs to be bug tested before it is merged into trunk. I am going to do some testing this weekend. If anyone else can join in with the testing, please do - the more usage, the more likely it is that we might spot a bug at this stage. We will follow the procedure detailed here to merge John's branch: http://miragroupware.org/wiki/doku.php/development/workflow and here: https://help.launchpad.net/Code/Review Shilpa has made very good progress on the Network layer. She has had to change almost all of the network protocol in order to implement Google Protocol Buffers. This will allow binary data transfer between Client and Server, because the messages are no longer parsed according to a special splitting character sequence. Instead, Shilpa's protocol first sends the length of the message, and then the message. Shilpa has already converted the Login, New User, and Join Group messages. Now that most of the groundwork is done, she will continue to convert the other messages over the next few weeks. Shilpa has been developing this on a local Bazaar branch. She would prefer to get the code stable before pushing it to Launchpad, but I suggested that she should push it to Launchpad and keep pushing new commits regularly in order to evade the conflicts that arose the last time that a major change was pushed in one go. Shilpa agreed to try to push her code to Launchpad the next time that she works on it. Zied has moved to a new job, and is now eager to contribute to Mira. (Welcome to the team, Zied!) He said he was interested in splitting Shilpa's task and working on converting some of the network messages to use GPB. Shilpa said that this might be difficult because some messages rely on other messages (such as the Login message, which also required changes to the List Workplace and Status messages), so it would be difficult to draw a line down the middle and split the messages between them. However, Shilpa said that she would look at the code and see if it would be possible to split the task between them. She will then email her conclusion to the mailing list. If it turns out that splitting the task would be too difficult, there are plenty of tasks remaining for Mira v0.2 to choose from: http://miragroupware.org/wiki/doku.php/development/roadmap/outstanding John would also like to change a few of the messages to make the database interfaces work more efficiently. For example, one change would involve splitting the message to update a Workplace into separate add subscription and delete subscription messages. He intends to make these changes once his branch has been merged into trunk. Finally, John mentioned that the links on the wiki to download the Qt libraries were broken. I have now fixed these. Best regards, Max Bossino Project Manager http://miragroupware.org |

Hi all, As you will have read, I have arranged a meeting for this Sunday, 18th September, at 22:00 UTC. I hope that you can join it! However, I know that a few of us find the current meeting time inconvenient. In order to fix this, I would like to conduct a quick, simple survey to see what time would be convenient for the majority of us. Please copy and paste the following 'table' and put a cross next to the meetign starting times that are fine for you on a normal Sunday: 13:00 UTC x 14:00 UTC x 15:00 UTC x 16:00 UTC x 17:00 UTC x 18:00 UTC x 19:00 UTC x 20:00 UTC x 21:00 UTC x 22:00 UTC x 23:00 UTC x (I can attend any of those times.) Once everyone has replied, we can put it all together and work out which time is best. Thank you! Best regards, Max Bossino Project Manager http://miragroupware.org |

Hi John, Thank you for that document - it is very helpful! If you don't mind, I will use it as the basis for the installation instructions in the Server's User Guide (for v0.2). I think you will obtain edit privileges automatically if you create an account on the wiki. Give it a go. If not, I will go into the admin interface and change your role. Ideally, we would merge Alan's branch into trunk and then yours, but I don't think we will create any conflicts if we merge yours with trunk first. Alan, what do you think?

Hello All, I wrote up a quick and dirty set of instructions for using either SQLite or MySQL databases for the Mira Server user/workplace data storage. It is hopefully enough to get you started if you wanted to use these database types. Note this is currently only in the dbBackend branch. I would like to update the Wiki's server Directory documentation. How do I get edit privileges on the Wiki? On more question. The DB Backend code is getting fairly stable (everyone yells "about time!"). What is the plan for getting this code merged into what will be the 0.2 release? I would like to start getting this code integrated. I guess that is it for now. Thanks, John |
