While mirroring, data fields not preserved, posted by Rob Calkins on Tue Oct 26 01:21:01 2021

While running two e-log books that were mirrored, I ended up with the situation of two entries with the same number/id. The mirroring did what
it said it would, increment the local logbook entry and grab the entry from the remote logbook. However, when it did, it did not preserve the fields in
the log book that are specified in the config file such as "Author", "Priority", "Subject" ect. I ended up with a very |

Too many open files - issue?, posted by Rob Calkins on Fri Oct 15 23:57:38 2021
|
Has anyone had issues with having too many files open? I'll setup my server and let it go but after a while, I end up with a lot of "cannot
create socket: Too many open files" errors being reported. I have a sync to another e-log going which I suspect is part of the cause since that
e-log server hasn't had this issue. I suspect that there are files being opened, going into some return loop code and then never getting closed. I'm |

The code segements you show are from the command line tool elog.c, not the server elogd.c. The tool is called to submit a new message from the command
line. Even if there would be a file not properly closed, it will be closed by the operating system once the program finishes. So no problem of too many
open files there. |

Hi,
I am trying to access elog through a python client (https://github.com/paulscherrerinstitute/py_elog) and found a strage strange behavior which
may be related server side problem. The python script generates get/post messages via the python requests library. This works fine so far and I can view |

Seems like I've discovered another bug here related to umlauts in my name. :D
I was submitting this post and forgot to put an icon. Elog seems to have saved a copy of my message, which I could not edit since my username
does not match the bugged name saved for this message. |

How about string constants in config files?, posted by Andreas Luedeke on Thu Oct 21 11:15:20 2021
|
My config files are often large and use some shell scripting. In these shell scripting part I interact with files and execute scripts in specific folder.
It would be nice to have the ability to define for example a file path once and reuse it in different parts of the config file. It would help to
make config files cleaner. For example: |

EDIT: forget the tip below. Instead just call script files: inline scripting in the ELOG config shows very strange behavior. Doing the same in external
scripts works reliable.

How to access PSI Elog data from other web clients , posted by Lin Wang on Wed Oct 13 02:38:34 2021
|
We want to develop separate mobile web pages for the web applications deployed at CSNS accelerator, including the PSI Elog.
In Elog, is there RESTful API or HTTP/JSON or HTTP/XML interface for other web clients to access?
Or is there any workaround? |

When elog has been developed, REST did not yet exist. The closest you can get is the RSS API. Just try https://elog.psi.ch/elogs/Forum/elog.rdf
and you see the result for this forum. To write to elog, you can use teh HTTP/HTML interface and mimic a browser. See for example elog:69209

Reverse proxy of Elog using Docker and Nginx?, posted by Andrew Wade on Mon Aug 13 21:09:30 2018
|
I've been trying to configured a Synology NAS to run my personal elog with a reverse proxy to the outside world. The best way seems to be running
Elog in a Docker instance and then running a separate connected Docker running a nginx-proxy (in this case jwilder/nginx-proxy).
This second container manages the certificates to letsencrypt and mapping URL requests to relevant containers so that connection is secured properly. |

Have you tried the "URL = ..." statement? This determines you elog redirects if you log in. If you reach elog through a proxy, the URL is a
different one that if you access it directly. In your case the proxy URL might be necessary.

Yes, I tried setting the URL parameter to the url used by the proxy. It goes to the correct address but that landing is the login page.

Actually this forum works through an Apache reverse proxy with authentication and it works, so I suspect that the problem has to do with jwilder/nginx-proxy.
Since we don't have this here, all I can propose is that you do debugging yourself. Run elogd with the -v flag so that you see all requests coming
from the user through the proxy. Compare the requests through Apache and Nginx to see if any argumets are stripped or mangled. Upon successful login, elog |

It does indeed seem to be a cookie stripping issue. I just need to figure out how to get Nginx to forward these properly.
Thanks for the help.

I have the same problem -- did you find a solution in using the nginx revese proxy with user login?
