When submitting entries via the elog client, I find that I can set arbitrary values for attributes that are supposedly "preset" and "locked".

As an example, I have in my elogd.cfg file:

[global]

...

Group Operations = Accelerator

Top group ATLAS = Operations

...

[global ATLAS]

Attributes = Experiment, Author, Author Email, Category, Subject
Required Attributes = Category, Subject
Options Category = Routine entry, Shift summary, Problem, Fix, Question, Info, Other
Extendable Options = Category

Preset Experiment =
Preset Author = $long_name
Preset Author Email = $user_email
Locked Attributes = Experiment, Author, Author Email

...

[Accelerator]
Attributes = Author, Author Email, Category, Subject
Options Category = Routine entry, Shift summary, Problem, Fix, Question, Info, Other

...

This works as intended with a web client (firefox). The Author and Author Email attributes are preset and unchangeable.

However, if I use the elog client, as in:

elog -v -h my.apache-proxy.server -d elog -l Accelerator -p 443 -s -u johndoe xxxxx -a Category=LN -a Subject=Test -a Author=IDoNotExist -n 1 -m entry.txt 
(johndoe is an existing user)

 
The entry is created with "IDoNotExist" as the Author name, instead of the correct name for the user johndoe,
and the Author Email attribute is blank.

Is there a way to enforce preset and locked attributes in the elogd server? (As a client could connect
with any arbitrary software, not just elog.)

In our installation, the sysadmin has therefore added the following section for the reload) part of the init script:

I did a force-reload of apache after making sure the modules are enabled. I also restarted elogd but to no avail. One symptom seems to be that the GET request is empty...that is before it was:

Any ideas?

 

 I have a similar problem when I restart the elogd daemon. To fix that, I usually also restart Apache.

I'm actually using elog on Debian and have been rolling my own ".deb" for a while now (starting with the old Debian
one and working my way up till 2.7.5). Maybe you could add the Debian /etc/init.d/elog script to the "contrib"
directory, with a suitable note in the README or something like that? That script has not changed in a long time and
is still functional - and doing so would make it easier for people who would like to install elog on a Debian (or
Debian-based, e.g. Ubuntu) system. I'll attach the script.

Regards,

Thomas

That makes sense. Might be worth adding a short Debian section to the installation instructions page?

FYI, Elog is no longer in Debian as of 2008-05-12.


Thanks,

George.

I'm also having issues with conditional entries in the Find page. If a conditional statement is used to hide attributes or change displayed attributes in the entry page then the attribute that is used in the conditional statement is not permanently selectable in the 'Find' page. It is available as a choice but as soon as selected the conditional action removes it? Is it possible to make conditional options/actions in the 'Find' page optional?

Hope that makes a little sense?

Many thanks

 

Many people want conditional attributes on the find page, so I cannot remove it. Before adding another parameter to disable this optionally, I would like to ask you to first try the "Show attributes edit = ..." option, which is not evaluated in the "find" page. Maybe you can achieve what you want with this option.

Stefan,

I have defined the "Bottom Text Login = ..." in each Logbook Configuration section. But when I use this option in the Global Section, ELOG fails to start.

 That's strange. I just tried myself following configuration file:

[global]
port = 8080
Bottom text = <center>Hello</center>
Bottom text login = <center>Login Hello</center>
Password file = passwd

[demo1]
Comment = General linux tips & tricks
Attributes = Author, Type, Category, Subject
Options Type = Routine, Software Installation, Problem Fixed, Configuration, Other
Page Title = ELOG - $subject

[demo2]
Comment = General linux tips & tricks
Attributes = Author, Type, Category, Subject

and everything works fine as can be seen from the login screen:

so can you check if above file works for you?
