Elog crashing at random intervals, posted by Lee Burnside on Sat Jan 28 22:23:46 2017

We're running Elog 3.1.2 om SL 7.2 and keep getting random crashes, sometimes when no one is accessing a logbook. The following is from /var/log/messages
with debugging turned on after the latest crash.

elogd crashes during SSL Mirror operations involving attachments, posted by Andreas Warburton on Mon Jan 9 17:15:56 2017
|
My MacOS (10.12.2) elogd version V3.1.2 is a recent git commit (edc5e85), due to the fix to my earlier-described issue solved in the thread here: https://midas.psi.ch/elogs/Forum/68519.
I am trying to (re-)set up Mirror functionality with a linux server running the standard public (V3.1.2-bd75964). I had initially updated
the linux server so that it also had the latest git commit (edc5e85), but could then not even add new logbook entries that involved attachments to it. |

The attached screenshot shows the behaviour after doing a synchronization (with Mirror simulate = 1) following first having ensured that the local (Mac)
and remote (linux) ELOGs initially showed "All entries identical" when doing a simulated synchronization, and then having edited local entries
9707 and 9709 by uploading (different) attachments to them. |

When I switch from SSL = 1 to SSL = 0 and I use http:// instead of https://, the ability to upload attachments to logbook entries returns. With
both Chrome and Safari browsers, with SSL = 1 the file upload hangs after only a small percentage of the file has been uploaded. I ran the following
openssl diagnostic on my elogd port. Would anyone have advice on what might be causing such errors? |

For the time being, I am deeming ELOG 3.1.2 unusable with https (SSL = 1) functionality on my "Debian GNU/Linux 7 (wheezy)" server
with "OpenSSL 1.0.1t", due to the described apparent issues with SSL. Reverting to http (SSL = 0) brings back my ability to upload attachments
and synchronize with a remote elogd running on a MacOS laptop. |

Further to my comment in https://midas.psi.ch/elogs/Forum/68549, if the described synchronization requires attachment(s) to be transferred from
my Mac laptop to the Debian linux server (with SSL = 0 set), it fails in all the tests that I tried.
To check whether these problems are linked to the OpenSSL version on the linux server, we also tried building an elogd executable using 1.0.2j |

"No SMTP host defined in [global] section of configuration file", posted by Luca on Wed Jan 18 05:25:44 2017

Hi,
I started re-using after a month an elog on my linux machine and, without any apparent reason since I did not used the machine at all in the
last month, every time I try to submit a post I get the following error |

These problems usually come when you are using a different configuration file that the one you think you are using. Note that you explicitly can tell
elogd to use a specific configuation file with the "-c" flag. Also make sure to restart elogd after major changes.

UTC time, posted by Luca on Mon Jan 9 15:39:59 2017

Dear all,
I am trying to have the elog timestamp in UTC time instead of local time using the following config file but without success. Do you know what
I am doing wrong? |
|
Re: UTC time, posted by Stefan Ritt on Mon Jan 9 17:18:15 2017

How do you believe that you can preset a Submission item? Preset only works for attributes, so you have to define an attribute like "Submission
UTC" or similar and preset this attribute with
Preset Submission UTC = $utcdate |

Dear Steve,
thanks a lot. Sorry but I am not expert of elog. I "inherited" from a colleague and wanted to see if I can keep it alive but to do
it I would need to move to UTC. Should this command affect the "INSERT CURRENT TIME/DATE" button? It does not seem to change. |

The INSERT CURRENT TIME/DATE button is not affected by this setting.

Hi Luca,
if you want to change all datetime properties to UTC time, then you'll just need to set the timezone on the server to UTC, before elogd is
started. |

Limit number of characters for "login user" parameter string ?, posted by Christine Quicot on Tue Jan 10 09:59:30 2017

Hello all,
I use ELOG for about 30 users, and I've listed their email adresses in the "login user" parameter, using the LDAP authentication.
As I had problems with the users from the end of the list (they couldn't log in the logbooks) I guessed that there is a max length for the string |

Re: Limit number of characters for "login user" parameter string ?, posted by Stefan Ritt on Tue Jan 10 11:13:02 2017

There is a limit of 100 options per line, so you probably run against that. This is defined in elogd.h with MAX_N_LIST and MAX_N_ATTR. You can try to
increase these and recompile, but at some point you will hit the stack size limit of your operating system and elogd will crash.

Is it possible to add custom menu commands, posted by Alex Kühnel on Sun Jan 8 19:26:29 2017

hi forum,
my question, is it possible to add a custom menu entry (f.e. "Auswertung"). I will start a new php page and do some system code starting
from the new page. I have attached a pic of my "Bereitschaftsdoku". |

Re: Is it possible to add custom menu commands, posted by Stefan Ritt on Mon Jan 9 11:00:53 2017

No, calculations are not easily possible with elog. You can write some Javascript code to pull out all minutes, add them up and manipulate the DOM tree
to show the results, but this requires some JavaScript knowlegde. Alternatively, export your table to a CSV file and do your calculations with a spreadhseet
program. |

How to make two attributes reacting with each other, posted by Xuan Wu on Thu Jan 5 12:55:05 2017

Hi all,
I have two attributes defined like following

Re: How to make two attributes reacting with each other, posted by Stefan Ritt on Thu Jan 5 13:24:06 2017

You can do that with conditional attributes (see documentation):

Sorry for my carelessness. What you said is definitely right. I just wonder how can Icon and Catagory change simultaneously whatever which one be selected
first.

If you select a (different) category, the current icon setting simply gets overwritten, what ever it was before.

What I mean is that, when I select a catagory, the icon will change. If I change the icon, I need the catagory change too.

IOptions does not support conditional attributes.

So, as far as I know that ROptions and IOptions doesn't support conditional attributes.
I think what you suggest is a nice idea. An alternative way is putting Category attribute before Icon attribute and adding a tooltip
to Icon attribute. However, I think your advice is better. Thanks! |

elogd crashes during Find and Mirror operations under MacOS, posted by Andreas Warburton on Sat Dec 24 10:40:00 2016

When installing ELOG 3.1.2 on my Mac Sierra (10.12.2) with the latest XCode 8.2.1, it seemed to install fine but for one warning when building elogd:

I have no experience with ELOG on OSX, therefore I can only give very vague and indirect support (sorry).
I suggest that you first try
an installation without actual logbook data (just move it to a save place for a while). Does a "find" still crash elogd?
If elogd
is still crashing, you should prune your configuration until it stops crashing. Submit the smallest config here that still crashes the logbook.

The current GIT revision (c017d07) fixes the problem with
the strlcpy() function (macOS 10.12.2, XCode 8.2). Can you try if that fixes your other problems, too?
Plese remember to use the recursive clone to get that version: |

Thank you very much (both Andreas and Stefan)! The build now runs without warnings, and I am now able to do Find operations without crashes. I
still am having some issues with the synchronization, but I suspect that this is elog-content related, so will in the coming days do some more testing
from CERN (where I have higher bandwidth with my home institution in Canada). Incidentally, I had to add a line to Makefile in order to be able to |

Ah, thanks for telling me. I added that to the Makefile. I did not need this because I had in my .profiel following line
export C_INCLUDE_PATH=/opt/local/include
which I need also for other macports-based projects. But having this twice does not hurt. |
