Hi, I have an issue with my local elog setup. it's usable but one function is just not working.

Problem

I'm getting weird error messages when trying to write or read entries from the CLI client.

I have googled a lot and most elog client examples are not giving the actual output, more like elog -h <host> -p <myport> -a ... -x -m "myfile" but I hope I got the options right.

Upgrading did not change the behaviour.

Question?

• anyone see problems in the commands I tried below
• with OSX in general
• have a recent setup on OSX that just works

Env

I'm running elog on my OSX laptop for tracking issues / improvements on client's IT systems. It's proven really good for storing my notes.

One "kink" is I kinda need both of them on the laptop since I cannot assume to have working network connectivity, i.e. when documenting network outages or datacenter maintenance where everything is off.

One thing I couldn't get to work was the CLI. Today I upgraded to the latest build, and tried again.

Env: OSX 12.4 (x86_64)

elog Client compiled from latest source tree (bcd7b50edd3d687425e6c5b0906dc02c8690a24e)

with minimal adjustments (turn off SSL since I can't get it right on OSX, rename two .c files in mxml to .cxx)

Outputs

$ echo "blah" | ./elog -h 127.0.0.1 -p 8080 -l intern -r 2 -x
Cannot retrieve host name: Undefined error: 0
$ echo "blah" | ./elog -h 127.0.0.1 -p 8080 -l intern -r 2 -x

As per the messages, I'm not entirely sure if it's an issue with the client or the server. upgrading both components made no difference.

Hey,

i'm trying to use curl to post new entries to our logbook as described here: https://elog.psi.ch/elogs/Forum/68597.
The Elog is installed via the Deban package on Buster.
I created a test logbook with attributes Author, Type, Category and Subject.

curl -u florian:foobaa -F cmd=Submit -F Author=Florian -F Type=Diary -F Category=General -F Subject="testing curl" -F Text="foo baa" http://localhost:8080/test

As you can see, curl only prints the login page of the logbook and no new entry has been created. Any suggestions what might go worng here?

Regards,
Florian

After going through the code of the Python API (https://github.com/paulscherrerinstitute/py_elog/blob/master/elog/logbook.py) I tried the following:
$ python3
>>> from passlib.hash import sha256_crypt
>>> sha256_crypt.hash( 'foobaa', salt='', rounds=5000)[4:]
'waa2sT6eBt.qk0wsucX/nxU5GcqffqlEx6ja5Lg1OR5'
>>> from datetime import datetime
>>> datetime.now().timestamp()
1599039390.964989
$ curl -F cmd=Submit -F exp=labor -F unm=florian -F upwd='waa2sT6eBt.qk0wsucX/nxU5GcqffqlEx6ja5Lg1OR5' -F Encoding=plain -F When=1599039390.964989 -F Author=curl -F Subject="curl test" -F Category=General -F Type=Diary -F Text="foo baa" http://localhost:8080/test/

This worked. It seems to me, that the "-u" option from Curl is not working for elog.

Hey,

I'm trying to integrate the Elog into our SlowControl System (Phoebus/EPICS). As a first step I translated the python library to Java. So writing new Entries and viewing them works.
But for Phoebus, you need a list of the possible values for the attributes. Currently this is done via the config file from Phoebus.

Is there a way to get the values also via a query directly from the Elog?

Cheers,
Florian

Thanks for the tipp. I managed to use XPATH to get the values for my Type and Category attributes!

The API, I'm developing for Phoebus is quiet simple. It currently just supports Author, Subject, Type and Category as attributes and the latter two are just lists of values.

Hey all,

In the configuration of the Elog one can use

Preset Author = $long_name
Preset Author Email = $user_email

to have predefined values for the Author and Author Email fields when creating a new entry via the web interface.
Is it also possible to use these placeholders when creating a new entry via the Python API?

Cheers,
Florian

I'm having a minor issue that were getting double entries due to the user is using the "submit" button more than once.

I seems like when there is a lag either on the machine or on the network it is possible to tap the "submit" button more than once resulting i a double or triple entry containing the same text and a almost identical timestamp.

Is there a way to aviod this?, my "solution" so far has been to select the entries and manually delete them. I'm using Elog version 3.14

Kind Regards Finn

Thank your very much for your work on this - as i mentioned this is a minor issue.

Kind Regards Finn
