  68208   Fri Nov 27 06:53:54 2015 Question David Dunneddunne@seven.com.auQuestionWindows | Other3.1.0If a Required Attribute starts with a number – No CKEditor
Hello, Is the below an issue or am I doing something incorrectly? Creating an attribute starting with a number and then including that attribute in the Required Attribute list prevents access to the CKEditior. This appears to be the case at least with FreeBSD (10.2 Rel) using Elog V3.1.0 and Windows 7 with Elog V3.1.1-3f311c5. The problem can be recreated using the Elog supplied sample config and adding the necessary attribute, sample config showing below. While attribute 7SWM is part of the Required Attributes the CKEditor fails to appear, remove 7SWM from the Required Attributes list and the CKEditor returns. [global] port = 8080 [demo] Theme = default Comment = General Linux Tips & Tricks Attributes = Author, Type, Category, Subject, 7SWM Options Type = Routine, Software Installation, Problem Fixed, Configuration, Other Options Category = General, Hardware, Software, Network, Other Options 7SWM = Name-1, Name-2, Name-3 Extendable Options = Category Required Attributes = Author, Type, 7SWM Page Title = ELOG - $subject Reverse sort = 1 Quick filter = Date, Type Thank you, David Dunne

Hi again!

I've another need that you probably already thought of :)

I'd like to be able to efficiently monitor a logbook for changes (new or edited posts) somehow. The most reasonable way I've found so far is to periodically poll a search that looks for posts after the time of the last poll. But that might note be very efficient, especially if the polling period gets short (or number of clients grows).

Is there some other feature that could be used for this? I was thinking maybe the ETag or Last-Modified HTTP header field could be used to show changes to a logbook by just reading the headers, but it would also require HEAD request support which does not seem to be there.

Cheers,

Johan

Use automatic email notifications or RSS feeds. Read the manual for that.

I recommend monitoring directly on the server. Here is an example of a very simply Python script (https://github.com/tamasgal/elog-slack) which monitors the files very efficiently and immediately pushes notifications to Slack (slack.com). Just look at the code, it's pretty straight forward and very easy to adapt it to other (web) services.

Btw. here is an ELOG entry of it https://midas.psi.ch/elogs/Forum/68224

Yeah, I found the RSS feed feature, but I could not get ETags/Last-Modified header fields which meant that I'd have to read and parse the entire feed every time. Maybe I made a mistake and they do work, but if not, I think it would make sense to implement as it should save work for both the server and the client.

Yeah, I suppose something like that would be both faster and more efficient than polling ELOG itself. Fortunately the ELOG disk format looks easily parsed.

Thanks for the pointer!

I just noticed that there are multiple messages per file, so I have to adapt the parser. I'll update this thread when I'm done!

You guys know that there is the possibility to execute an arbitrary script on each submission of a new messge? Just use "Execute new = <script>". In the script you have access to all parameters of the message. That's maybe simple than to watch the file set.
