emaillog.php returns no data

[eSrem]

I am running 2.1.2 (20111019) and the block installed fine. This is an older website that has been through several upgrades. Before installing I made sure that all references to quickmail were removed from the codebase and the database. With the latest build available from the official moodle plugin database I have one major error; on the emaillog.php page it returns no data. Whether I want to check for drafts, or the history of messages in general.

The browser displays a (net::ERR_EMPTY_RESPONSE). Our client has informed me that on your clean 2.1.2 installation the module runs fine; without the server closing the connection on the emaillog.php page. The biggest hint I could figure out is that I don't see the emaillog.php requests in webservers acces logs. Though, I made sure all the directory rights and ownerships were set properly.

I am wondering what could be wrong with our setup and/or with the module. I hope we can work together towards a solution so that we can provide a bigger knowledgebase to other users of this block running into this issue.

I have had a discussion on this with our programmer. He went and searched for what was causing the net error. He found that in the function "list_entries" in "lib.php" something is amiss. It is using a function what is supported only in 5.3.8 and not in our installed 5.3.6. By upgrading PHP we fixed the problems we were having.

To elaborate on this issue...
The anonymous function used in list_entries doesn't appear to be working correctly in 5.3.6.
I believe this to be a PHP bug, as the process didn't segfault, but just gave no output at all.
However, this was fixed in PHP release 5.3.8.

I would suggest adding a notification for users to use 5.3.8 :).

@LCHEB, ha, thanks for that.

I would have never guess that anonymous function behavior would change between versions, and it actually saddens me to think a language would. At any rate, I think the safest solution here would be to replace the problematic anonymous function with code that is not wrapped in an anonymous function, as I don't think it is right for the Quickmail module to require any other version of PHP than Moodle's required version. I'm looking into that right now.

This discussion can now be moved to issue #8. Thank you everyone for bringing this to our attention.
