my ELOG sometimes dies with "deadc0de", do I have too large ELOG config or logbook? Or is it simply a bug?

What can I do to solve this problem? "ulimit"? Or some trace output from elog?

 This seems an internal memory allocation problem. Can you reproduce the error? Can you reproduce it with the minimal configuration file coming with the distribution? If you know how to run a program inside the debugger, you can send me a stack trace when the problem occurs and I can check it.

I can produce the problem, but it is related to the information in the logbook which I cannot share...

Configuration:

I know nothing about gdb. Here are my stumbling attempts of using it, please tell me how to use gdb:

The above "deadc0de" came from when I submitted an entry.

 

Where is one (note that it is another elogd version), I search all logbook for "pure .* ring" in subject in "Mode: Raw".

 I'm also having this problem.

It's reproducible, It happens if I try to view a certain entry (or the main list page when that entry is near the top), but goes away when I remove the datafile for that entry.

The file is quite large, since it contains several long entries in HTML encoding with some tables and stuff.

The problem is related to the long entries. It has already been fixed in revision 2141 last month. So please upgrade to the current version.

 I already tried this. I'm using 2156 (latest from SVN) and no joy.

  67752   Fri Jan 16 13:41:18 2015 Entry Eoin Butlereoin.butler@cern.chRequestAll-Configure default time range in 'Find'

Hello,

We have a very large elog database, and executing a 'Find' on the whole range takes several minutes, locking other users out of the elog for that time. It would be very nice if there could be an option to set the default value of the 'search last ...' option on the find page. Thanks in advance!

  67754   Mon Jan 19 11:09:31 2015 Reply Eoin Butlereoin.butler@cern.chRequestAll-Re: Configure default time range in 'Find'

Yes, this works, but users inevitably forget to select "last week" or whatever, and just leave it blank, which means their search unintentionally takes a long time. It would be much better if one could configure it to default to something "fast".

Stefan Ritt wrote:

Have you tried in the "Find" page to set a start date, or select "Show last: Month". This shoudl speed up searching quit a bit.

  67760   Thu Jan 22 17:04:03 2015 Reply Eoin Butlereoin.butler@cern.chRequestAll-Re: Configure default time range in 'Find'

This looks like exactly what I wanted, thanks!

Stefan Ritt wrote:

I added a new optoin "Show last default = <days>", where one can pre-set the "Show last" drop-down box. I think this is a good idea, so now people can configure their elog to a certain default in this parameter. Of course all settings in the Find page are AND'ed together, so if one restricts the search to tha last week, but then looks for a date more in the past, the result will be zero by definition. The change is in the GIT repository. If you cannot recompile the code yourself, you have to wait for the next release.

David Pilgram wrote:

By the way, in further testing, the "Show last" selection over-rides whatever two dates are selected, so if you ask for any entry in Dec 2014, but the "Show last" selects "week", nothing is found - very quickly.  I trust that is what you're after, Eoin.  I'll keep my change to the coding, but that's personal choice.

Hello!

We're setting up ELOG on OpenShift. ELOG is installed on a Alma Linux 9 image. The container and the elog demo works fine executing the docker image locally.

When deployed on OpenShift, we get a weird response, that results in a 502 Bad Gateway. The broken response looks like:
