No operations allowed after connection closed.Connection was implicitly closed by the driver.

[tenniscp25]

I developed a very simple app using squeryl-record. It works fine
until I leave it for about 8 hours. Then, every page that hits the
database results in the following exception chain:

java.lang.RuntimeException: Exception while executing statement : No
operations allowed after connection closed.Connection was implicitly
closed by the driver. errorCode: 0, sqlState: 08003
...
...
Caused by:
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException:

I've tried lift 2.3-M1, jetty 7.3, tomcat 7.0.5, production mode,
development mode, lift-managed connection pooling and server-provided
jndi datasource to no avail.

Please suggest how to fix this.

Here are my code and other details:

This sounds like a part of the discussion that we were having earlier about Lift's LoanWrappers and the DB singleton that manages connections.

It'd be great if Squeryl could us Lift's connection pooling system when running in Lift apps.

Dave, I think I know what the problem is, he *is* in fact using Lift's connection pooling, because he uses this initialization method :

https://github.com/lift/framework/blob/master/persistence/squeryl-record/src/main/scala/net/liftweb/squerylrecord/SquerylRecord.scala#L52

The second one described here in the initialization section :

http://www.assembla.com/wiki/show/liftweb/Squeryl

From Squeryl's perspective, he is using : a (Squeryl) session created by : SessionFactory.externalTransactionManagementAdapter

(see : https://github.com/max-l/Squeryl/blob/master/src/main/scala/org/squeryl/Session.scala#L92)

So far, everything *should* be good, but it isn't... What I think is missing from the squeryl-record integration is the 

call to this cleanup block:

 if(Session.hasCurrentSession) {

   Session.currentSession.cleanupResources

   Session.currentSession.unbindFromCurrentThread

 }

at the end of Lift's transaction block (right before Lift closes the JDBC connection)

If Lift has such a callback (I'm pretty sure it does) please make sure the above snippet gets called.

Can someone instruct us on the Lift callback to use for this ?

Of course this would be a work around, until the callback gets registered in

the squeryl-record initialization.

It throws those exceptions even if I'm using Tomcat's JNDI DataSource.
Doesn't the JNDI DataSource automatically do connection pooling
internally?

Please correct me if I'm wrong.

Thank you.

Thanks David and ML,

Yes, I initialize Squeryl with this code:

DefaultConnectionIdentifier.jndiName = Props.get("db.jndiName")
openOr "jdbc/tr"

if (!DB.jndiJdbcConnAvailable_?) {
logger.info("No JNDI data source for: " +
DefaultConnectionIdentifier.jndiName)
val vendor =
new StandardDBVendor(Props.get("db.driver") openOr
"org.h2.Driver",
Props.get("db.url") openOr "jdbc:h2:tr;AUTO_SERVER=TRUE",
Props.get("db.user"), Props.get("db.password")) {
}
logger.info("Using " + vendor + " instead.")
LiftRules.unloadHooks.append(vendor.closeAllConnections_! _)
DB.defineConnectionManager(DefaultConnectionIdentifier, vendor)
}

SquerylRecord.init(() => new MySQLAdapter)

and this props file:

db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost/tr?
createDatabaseIfNotExist=true&useUnicode=true&characterEncoding=utf8
db.user=tr
db.password=tr

In fact, I tried both Lift's connection pooling and JNDI DataSource
(which I think it does some kind of connection pooling internally
too). Either way, the application still throws that exception.

If this is the case, then, yes, Tomcat is responsible for insuring that the connection is still alive before handing the connection to your code.

Dave (or Lift experts reading this), is there a callback in Lift for when sessions are closed ?

If yes, tenniscp25 (...don't know your name..), register this snippet in the callback :

--------------before connection close OR after transaction commit callback --------------

 if(Session.hasCurrentSession) {

   Session.currentSession.cleanupResources

   Session.currentSession.unbindFromCurrentThread

 }

We never close connections until the end of the application run.

 if(Session.hasCurrentSession) {

I added the following code after
[[ S.addAround(DB.buildLoanWrapper) ]]. Let's see if it works.

S.addAround(DB.buildLoanWrapper)

S.addAround(new LoanWrapper() {
def apply[T](f: => T) = {
val ret = f
if (Session.hasCurrentSession) {
Session.currentSession.cleanup
Session.currentSession.unbindFromCurrentThread
}
ret
}
})

It's been a while since I've used MySQL, but I do remember that in the past there were issues with connection pools holding connections that had been timed out by the MySQL server.  See this page: http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-configuration-properties.html and the autoReconnect property (High Availability and Clustering) in particular.  The server drops unused connections after 8 hours by default (which seems to be the behavior you are seeing) and Tomcat or whatever other connection pool is in use wouldn't be aware that the connection it holds can no longer communicate with the DB.

[tenniscp25]

Thank you again.. I tried both cleanup code and autoReconnect
attribute. Neither works. :-(

[David Whittaker]

I should have been more clear... I wasn't suggesting the autoReconnect param as a solution, the documentation I sent you even recommends you don't use it, I was just trying to bring the MySQL behavior to your attention.  Even with autoReconnect on you'll still get at least one SQLException after the timeout, the setting just lets the driver know to reconnect afterwards.  What I had ended up doing years ago to deal with this was to configure Tomcat's DBCP connection pool to send a very simple query every time a connection was requested and verify that it was still valid.  That's obviously not a great long term solution.  From my experience, switching to Postgres is :)

[tenniscp25]

Thanks David. I overlooked the details in the documentation. :blush:

I ended up using Tomcat JDBC Connection Pool (http://people.apache.org/
~fhanik/jdbc-pool/jdbc-pool.html), and it works! In fact, I already
tried setting DBCP's validationQuery attribute before starting this
thread. I don't know why DBCP previously failed to throw away the dead
connection, but I think I must have done something wrong.

Anyway, thanks again for stressing this is MySQL problem.

[Alex Siman]

Hello!

Any updates on this issue? I have the same problem with Record+Squeryl+MySQL.

Mybe this can be fixed by using some connection pool?

As a quick solution I am considering to rewrite Record+Squeryl to Mapper.

[Alex Siman]

OK, just setup BoneCP as Squeryl connection manager and request-spanned inTransaction in LoanWrapper.

Will see if any errors occured.

[David Whittaker]

Alex,

I assume that you were originally getting the error using Lift style transaction management (https://www.assembla.com/spaces/liftweb/wiki/Squeryl#Initialization)?  If so, the connections are pooled by default and that leads to the error.  Mysql times out idle connections so any that are in the pool that haven't been used for longer than the timeout interval will throw an exception when you attempt to use them.  You're likely to see the same issue with BoneCP and Squeryl transactions.  See the earlier messages in this thread for info on how to change the timeout interval in Mysql or set the autoreconnect flag in the connection URL (which I don't recommend).

BoneCP should be making dummy keep-alive sql statements to MySQL provided it's configured correctly. Please refer to BoneCPConfig.java for a list of all configuration options.
