Hi

Thanks for elog - it's a brilliant piece of software.  I'd looked all over for open source software to log/manage change requests before discovering elog; it's so flexible that I've been able to do everything I need with it.

However, I think that I've just discovered my first undocumented 'feature'.  Attribute names containing punctuation characters (e.g. / and :) cause "Redirection limit for this URL exceeded" errors in Firefox 3.0.2 and corrupt the URL if they're used in a Quick Filter.  I often use '/' in attribute names for brevity, e.g. "Old/New Versions" but hadn't used one in a Quick Filter before.

keep up the good work.

regards

Steve

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

Configuration:

[global]
port = 8000
Main Tab = Home
Password file = elogpasswd.txt

Self register = 0

Display mode = summary
Suppress Email to users = 1

[General]

Options Type = Configuration, Information, Documents
Extendable Options = Type
Required Attributes = Type
Page Title = ELOG - $subject
Reverse sort = 0
Quick filter = Date, Type

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".

Quick answer: Don't use '/' in attribute names ;-) but I guess you were kind of afraid to get this answer.

Somehow longer answer: I tried to reproduce your problem with following configuration:

[demo]
Attributes = Author, Type, Subject, Old/New
Options Old/New = Old, New
Quick filter = Type, Old/New

But I was not successful. Everything worked fine using ELOG V2.7.5-2137. Can you please check with the above configuration and tell me exactly when the redirection problem occurs? Is it during filtering on already on creating a new entry?

> elogd continues to run after a SIGHUP. If a second SIGHUP is received the daemon terminates.
> This was observed on Solaris 10 (SPARC).
> The documentation states that elogd should re-read configuration after receiving SIGHUP.

I tried to reproduce this but without success. I could send many SIGHUPs without the daemon terminating. Maybe 
you modified the configuration file in between and elogd barked out because of some wrong configuration? Try to 
start the daemon interactively and see what exactly happens if you send several SIGHUPs.

Very good idea! I changed that in ELOG V2.7.5-2139. The fix will be contained in the next release.

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.)

Indeed "preset" and "locked" attributes are not obeyed if entries are submitted via the elog tool. The is because if you use a browser, the input form is created by elogd. If you use a locked attribute, the input filed for that attribute is not shown for example. If you use the elog tool, it directly submits an entry not knowing anything about the input form. To make this work, elog would first have to request the input form, then interprete all the HTML, figure out if an attribute is locked or not, then display an error if you try to submit that attribute. Since parsing of HTML is not implemented in elog, this is currently not possible. 

Originally I thought that this is not such a problem. Mostly elog is used to produce some automatic entries, where the authorship is of minor interest. But I guess you are afraid that one use could submit an entry under another user's name, right? Well, I hoped that in scientific collaborations nobody is that evil ;-)

Well, I will try to do something here in order to fix this. Will come back to you.

Actually I found a way around. The "Subst xxx" is evaluated after you submit an entry, so it also works for the elog tool. So all you need in your config file is:

Subst Author = $long_name

and it will do the job.
