There is a nice js plugin to create formulas with a latex editor.
This plugin (Can be found at http://www.codecogs.com/latex/integration/ckeditor/install.php) is for the CK Editor.
Currently the FCK Editor is used, which has been superseded in 2009 by the CK Editor.
It would be nice to change ELOG to use the newer CKEditor, in order to be able to use the formula plugin (and
maybe other plugins as well later).

When I run a mirror server and both logbooks using SSL/KRB5 then the cron job causes a segmentation fault.

I haven't tried to check it with a simple configuration yet.
My set-up: two elogd on same server, one running "german" on port 444, the other "english" on port 445.
Both are behind an apache webserver configured reverse proxy, to hide the ports for external access.
I'll try to reproduce the fault with a "minimal configuration" soon and report again.

Does anyone know whether ELOG has limit number of entries or it can create new entries as many as it can go?  Thanks.

The number of entries is not limited. But if there are very many entries, searching can get a bit slow. We have installations with ~100'000 entries and they work still fine. 

Hi,

when I try to edit an entry of my ELOG, the display shows the editor window blank, without all the previous content of the entry, and it is not possibile to write in it. It worked since yesterday, when ELOG tried to save a new entry but the disk was full. ELOG was srewed up. I deleted the buggy entry and now I can display all the previuos entries, but I cannot edit anymore... Please help!

 I've a little experience of digging myself out of (in my case, self-induced) problems using ELOG.   I'm also aware that I may be the least experienced/qualified user..

First:  Archive your work directories.  Then at least whatever you do from here, you've got the status quo to fall back on.  Also, record anything you can remember (ID number, thread, etc) of the deleted entry/entries.

I've found that ELOG can hang in an infinite loop if it tries to find an entry that is no longer there - and that depends upon how you approach the point where the missing entry would be.  ELOG's own delete works fine in normal circumstances.  I'm talking about abnormal circumstances, for example when idiots (me) are playing around with the yymmdda.log files, or *possibly* if the disk is full, and you then try deleting the entry that caused the full disk problem.  Whether that is what you are seeing, I cannot say at present. 

However, to progress this:  When you are stuck, unable to edit anything, in a[nother] terminal, try the process report

ps -A

two or three times, with a short interval between commands.  (Or other switches if you know how to select to view the elogd process on your system).   If elogd is using seconds of CPU time between each ps command, it's probably in an infinite loop.  If you need to be sure, wait a minute and check again.  If so, you'll have to stop the daemon, possibly requiring a computer reboot.  In my experience, ELOG does not get stuck in an infinite loop when just indexing the pages when the daemon starts, but experts may well know better.

This may at least diagnose whether you cannot edit because ELOG is stuck in an infinite loop, or has some other cause.

If it is the infinite loop, the trick is to find which entry causes the loop without getting stuck in that loop next time around.

 Hi David,

you have been very helpful indeed. The problem was the one you spot, I've deleted the  buggy entry removing the ***.log file, and this caused disaster..... now it is working again, thanks a lot, I have all my PhD thesis in ELOG....

Sara

Don't get too excited yet!

When you reply to an entry in ELOG, then some additional data is added to that original entry. 

So, if you reply today (say 02/06/11) to an entry made yesterday, then you will find that the file 110602a.log has a large change (the new entry in full, plus elog extra codes), *and* an additional line added into 110601a.log.  Deleting 110602a.log will not remove the line in 110601a.log, and that could still cause problems, that is, wandering into an infinite loop.

To save a lot of effort, I'll suggest that you (a) keep the back-ups up to date, and keep two (the latest and the one before that); (b) proceed carefully at least to start with.  If you fall into the infinite loop again, then flag it up and I (or someone else) will be able to give further pointers.

So unless you are sure that

Since you used the -a switch for ls, the current directory '.' i.e. work/ is included in the list. I have the same kind of output. No worries.

Are you experiencing problems with ELOG?

 Hi Stefan,

First : Compliments with your fine application !

The issue : A user wants to search the database. He selects one of the quick filters (e.g. "Show Last / Month"). Next he fills in the form and as long as text boxes are used there is no problem. But when he chooses a value from a populated drop-down list, the quick filter disappears. Other way round (first drop-down list and then the quick filter) no problem.

Kind regards,

Peter de Mol

all instances of elogd use the same file name in /tmp when calling my_shell.  This can cause some inconsistent behavior when two or more copies of elogd are runnnig at the same time.  (eg. one might detect ImageMagik is installed, and the other not,)

The propsed solution is to have the parent read from a pipe to the child rather from a file.  A patch is attached.

With the recent Elog 2.9.0 rev 2412 the Self Register = 3 option doesn't work as expected: The user is immediately allowed to login. This is not what this option was doing, which is to wait for an approval by the administrator. Can this behaviour be restored, or should I change the value of the Self Register flag? Thanks

Are you sure about that (maybe used an older revision of elogd where this indeed was a problem?). The current V2.9.0-2412 gives me this:

If I then log in as the admin user, I see the configuration of the new user, but the account is not activated:

So the user cannot log in. The config file is:

[global]
port = 8080
password file = passwd
smtp host = mail.psi.ch
Self register = 3
Admin user = stefan

[demo1]
Attributes = Project, Category

Can you double check?

 HI Stefan,

I tried again and confirm the version number. I never got this pannel saying that my request will be processed by an adminstrator. Maybe the installation was incomplete? Is this pannel outside the standard src files?  I receive the mail as administrator, but the accout is already valid BEFORE I validate it.

This was working in previous versions, i.e. the entry was not created at all. And login wasn't possible.

We went back to 2.8.0 as the server is regularly crashing with 2.9.0 and we have to keep it alive for our running experiment. We are trying to isolate and reproduce the problem...

Try to use the simple config file, and see what happens there. Maybe it's a config option you use differently in the experiment. If you identify the config option which triggers the problem, I can probably reproduce it and fix it. Concerning crashes of 2.9.0: We have it running stably for our experiments, that's why I released it. But there are major changes since 2.8.0, mainly the Kerberos authentification (actually people from CERN asked for that). So it could be that in your case there are problems I don't see. In that case you have to test with which options in the config file the problems start. If elogd crashes, a stack dump would maybe also be helpful for me.

 Dear Stefan, after a long time I managed to get a test setup. The line that creates the misbehaviour is

Guest Menu Commands      = List, Find, Login, Help

which seems inocuous! But with this line a user with inactive account can login without validation. Without this line I get also the proper web page indicating that the account has to be activated when I register as new user.

Another little annoyance: When a user is prevented from login ("The account is currently deactivated") there is NO WAY to login, as any action with Elog tries to use the (non activated) username and password. I can't get back the login page!

Thanks

Great. This this description I could reproduce the error and fix it. The fix is in SVN revision 2414.

Cheers, Stefan. 

 If you could also obtain the display of the message "Your request has been forwarded to the administrator.You will be notified by email upon activation of your new account." when a new user apply in the presence of the Guest Menu commands, that would be perfect. Cheers
