exiqgrep fails to parse output of exim4 -bp if the mail message is less than 1k

[Milton Ngan]

If you have a message in the queue that is less than 1k in size, exiqgrep will fail with a message like this:

Line mismatch: 2m 719 1SZe77-00047t-V9 <email address hidden>

The problem is that the regular expression requires there to be a suffix on the size. Based on the previous implementations of exiqgrep, it looks like a ? is missing after the [A-Z].

- if ($line =~ /^\s*(\w+)\s+((?:\d+(?:\.\d+)?[A-Z])?)\s*(\w{6}-\w{6}-\w{2})\s+(<.*?>)/) {
+ if ($line =~ /^\s*(\w+)\s+((?:\d+(?:\.\d+)?[A-Z]?)?)\s*(\w{6}-\w{6}-\w{2})\s+(<.*?>)/) {

exiqgrep is containted in package exim4-base.

The affected version is 4.76-3ubuntu3.

This is fixed in upstream Exim version 4.77; compare the regular expression:

upstream v4.76: $line =~ /^\s*(\w+)\s+((?:\d+(?:\.\d+)?[A-Z])?)\s*(\w{6}-\w{6}-\w{2})\s+(<.*?>)/
upstream v4.77: $line =~ /^\s*(\w+)\s+((?:\d+(?:\.\d+)?[A-Z]?)?)\s*(\w{6}-\w{6}-\w{2})\s+(<.*?>)/

-- note the optional size suffix in the later version: [A-Z]?

[Daniel Bond (daniel-bond)]

Is there any chance of this being fixed via StableReleaseUpdates ( https://wiki.ubuntu.com/StableReleaseUpdates ) ? Or perhaps it would be better to request a backport for it?

On a busy production Exim4 server, there will almost allways be an email in queue, with a size less than 1K. This makes exiqgrep not work, which again makes monitoring with munin not work. Without monitoring, 12.04 is not ideal for running production Exim server.

[Andreas Metzler (k-launchpad-downhill-at-eu-org)]

Just to be crystal-clear: This was fixed upstream in 4.77. 196f5966a092d873df256956f6f88d4b5d3cb803

[Rarylson Freitas (rarylson)]

I had the same problem. When I read the source-code of the exiqgrep (exim-base package), I realized a question character was missing, and I applied the same patch.

I'm using the 4.76-3ubuntu3 version too.

So I was going to report the patch when I discovered that this bug was fixed in new versions (4.77).

Is it possible to apply this patch to the Ubuntu 12.04 eximqgrep release?

[Rarylson Freitas (rarylson)]

It seems that this bug is not more present in Ubuntu 14.04 (exim4-base version 4.82-3ubuntu2).

However, we've really liked if the Ubuntu Team merged this simple fix in the Ubuntu 12.04 LTS. It isn't good to be obligated to update the distribution just because only some fixes are merged in the old long-term-supported version.
