Cannot Set Connection To Blocking Mode In Unknown

The 'cannot set connection to blocking mode' is trivially repeatable with large enough queries to fill the send buffer (padding with spaces at the end is enough). Or to install a custom error handler that silentlyignores this error.However, after carefully considering all options, IMHO i think thatremoving the line in the PHP sources that raises the error is Is anyone else experiencing this? Both these methods suffer from the same issue and are already too broken to be used in production environment, unless the connection is made to 'localhost'. http://culturahq.com/cannot-set/cannot-set-connection-to-blocking-mode.html

Zero means "no error". This information was last pulled 9 hours ago. That means the scriptthat prints the error and/or handles the error in its custom errorhandler may have nothing to do with the broken database connection.Actual result:--------------Notice: (null)(): Cannot set connection to thank you in advance, sorry for my bad english.. * The case: *********** ONE IN SEVEN attempt of show/refreshing the page, it always show something like this at the end of http://stackoverflow.com/questions/865017/pg-send-query-cannot-set-connection-to-blocking-mode

Heh, shouldn't moderate when I'm distracted. Real-Life example: The company i work for has this problem currently in one of our applications. I do not know if this could affect later calls that would reuse this connection.

Basically it could occur in scripts that would normally notcause an error at all. My point is that cause and effect of the error are disconnected. None, the status of the bug is updated manually. The problem is caused by the implementation not following the PostgreSQL documentation at http://www.postgresql.org/docs/9.1/static/libpq-async.html#LIBPQ-PQFLUSH "PQflush: [...] After sending any command or data on a nonblocking connection, call PQflush. [...]" Related PHP

This can be a script that is executed sometime afterwards - maybe a long time afterwards, maybe in a script that never opened a database connection. The whole purpose of the two PQ_SETNONBLOCKING calls is to put the connection in non blocking mode to allow asynchronous execution and putting it back to the default blocking behaviour afterwards. The pg_query seems to randomly generate this error if previous connection was automatically rolled back when "new" connection is acquired with pg_pconnect().

For the time being, I suggestto use @ operator or define your error handler so that the error isignored.------------------------------------------------------------------------[2005-01-04 22:39:30] mike at ecommerce dot comDescription:------------Problem Description:I have an issue with a So if you need a fix for an existing stable release, please comment with a justification against https://wiki.ubuntu.com/StableReleaseUpdates#When and complete steps 1 through 4 in https://wiki.ubuntu.com/StableReleaseUpdates#Procedure - and go ahead with share|improve this answer edited Sep 26 '12 at 9:19 answered Sep 25 '12 at 12:19 J. pgsql.auto_reset_persistent = Off ---- Previous Comments: Yohgaki at ohgaki dot net at Jan 18, 2005 at 8:36 am ⇧ ID: 31411Comment by: yohgaki at ohgaki dot netReported By: mike at ecommerce

Restart postgresql for whatever reason. Basically it could occur in scripts that would normally not cause an error at all. yes no Are you using the same operating system? Thedatabase link is removed anyway from the list of persistentconnections, due to the "return -1;" directly afterwards.I am aware that there are other solutions, like adjusting"error_reporting" not to include E_NOTICE, or

It looks like the current development version already has this issue fixed, so I'm marking this bug as Fix Released. With smaller queries I imagine it is dependent on load, and rather intermittent.
