I recently upgraded elog from 2.7.8 to 2.8.0 (and moved servers, removed unused logbooks, etc.). I'm now having a problem where elog consistently crashes when attempting to edit multiple entries. This is a very common use case, as we use a "status" field, set to "open" or "closed" to track problems. When a problem is resolved, we will go to the "list" display, set it to "threaded", "select" the thread, and then edit it, to change the status field for all posts in the thread to "closed".

Now, as soon as the "edit" button is clicked, elog crashes. This happens on every thread and logbook that I've tried. The elog logfile itself doesn't show anything useful.

However, if eLog is run with "-v" in place of "-D", it does not crash.

 

Environment:

        CentOS 5.4

        eLog 2.8.0 built Aug  5 2010, 12:24:11

 

 

I'm now running eLog  2.9.0 and seeing the same crashes. However, I've got some more information that may be helpful.


The crash seems to be directly related to the order of replies in the thread. For example, in this thread I am replying to the original entry. The original entry has 2 children (the entries are siblings) and no grandchildren.

In our installation, eLog crashes consistently under the following conditions:

       go to the "list" display

       set it to "threaded"

       "select" a thread that has siblings at any generation of replies

       choose "edit"

If the selected thread only has one entry at any generation, eLog does not crash.

 

Here's a horrible attempt at a display of two message threads. Note that in the first example, there are 2 replies at the same generation (siblings)--both the person who responded and the original submitter replied to the initial submission. After that, all replies were to successive generations.

 I am also experiencing the same exact problem as explained above. It only seems to happen when a part of the title has changed. I will include my config for an example. Make a few entries, then change the "Customer" paramater. Then try and edit an entry in the thread.

 

 

 Enable attachments = 1

Attributes = Employee, Customer, XXX-ID, XXXX Number, SCD, Type, Status, Folder Created, XXXX Received, Equipment Installed, XXX Carrier Up, Customer Carrier Up, QA Completed

Options XXXX Received = Yes, No, N/A
Options Equipment Installed = Yes, No, N/A
Options XXX Carrier Up = Yes, No, N/A
Options Customer Carrier Up = Yes, No, N/A
Options QA Completed = Yes, No

Entries per page = 100

Preset Text = $short_name @ $utcdate -
Append on reply = $short_name @ $utcdate -

Locked Attributes = Employee

Preset Employee = $long_name
