No. Just install the new version over the old one.

thanx, so in linux I just need to install over the old ones?

I thought there are additional step on linux, hehehe thanx for the help sir

Hi all,

We've been happily using ELOG for years, but ran into an odd problem when replacing the old Solaris server that ran the ELOG with a newer box running Ubuntu. 

Basically, when I try to search the log, the URL seems to be malformed. I.e. the form produces the query string:

?mode=summvry&reverse=0&reverse=1&npp=35&m&y&Authorthor=ericq

Instead of a functional one like:

?mode=summary&reverse=1&npp=35&Author=ericq

We're running v2.8.1, since we like using the global write password mode; our log is viewable here: http://nodus.ligo.caltech.edu:8080 Any ideas what could've gone wrong? Installation was pretty straightforward, the code compiled happily on the ubuntu machine. 

Incidentally, I notice this logbook is running V3, using CKeditor. Any hints when these might be available for public use?

Thanks!

Old versions are not supported any more. I only can fix bugs in the current version. Probably the bug you report is already gone (just give it a try). If you need the global write password mode, you can enable guest read access to your logbook and define a single use with the write password, that's then almost equivalent.

/Stefan

yes I mean functionally of elog or how to download files at elog?

 Dear Stefan,

I am having a log book with the 5 logbooks. All other books are working fine except only one, every time while submitting the entry I am getting a error message.

I have attached the screen shot along with the error log file.

Please help me in solving this bug.

Regards

Harish Amin 

It's hard to guess from the information you sent what is wrong. The program just crashes, after the email notification has been sent successfully. Can you check if the one logbook which is not working is using some path for the logbook directory which it cannot write to due to access limitations? Just a guess.

-Stefan

 Dear Stefen,

I am attaching the config file details of the the logbook which crashes. Please check and reply.

The maximum number of attributes is limited to 100, you have 111. Plus you use the attributes "Start Time" and "End Time" more than once. In a future version of ELOG I will add some checking for this, so that you get a proper error message. You can increase the number of attributes, but then you have to recompile elog. I would suggest separating your information into several smaller logbooks.

Dear Stefan,

Thank you very much - Now its working perfectly fine. 

Thanks once again for your valuable time & help.

dear stefan

I have a problem how to bring up the menu page menu elog download?
thank you

Can you please be a bit more specific? Do you mean the web site to download elog? Or is it some functionality of elog?

Thank you. 

Hi Stefan and Andreas

Yesterday I reported I had some issues with the latest elog: but now I can reproduce one.  
elog 2.9.2-a738232

I started a new entry, and attached three pdf files.  I did not get the problem of not seeing the png thumnbnail
this time, although that is annoying if you want/need to adjust the thumbnail image before submitting.

However, if I then look at the running processes, I have the following listed (ps -A)

23677 tty1     00:00:04 elogd
23809 tty1     00:00:00 elogd <defunct>
23825 tty1     00:00:00 elogd <defunct>
23847 pts/0    00:00:00 ps

23677 was when I started the elogd daemon, having killed off the previous daemon etc for test purposes.

23809 and 23825 appeared after a couple of pdfs were added (second and third ones to be precise).  They can only
be killed off by killing off the original running daemon.  It appears that attaching a second and further pdf
attachments to any entry generates an elogd <defunct> in the processes list, although attaching a jpg in the
middle of a list of pdfs didn't (but the next pdf did).  This is happening while adding attachments, that is the
Submit button has yet to be pressed, so it seems to be generated  when the pdf file is being processed for some
reason.

You can end up with quite a stack of these in the process list!

I never saw this behaviour with the previous version I was running, SVN2475 I think.


By the way, I still cannot send an attachment over to this server (showing a screenshot) without the 502 error.

Further work suggests that the type of pdf file might matter, as I have now seen the defunct daemon after
adding the first pdf file in an entry.

However, I have also found that image manipulation (rotation, size) generates a defunct daemon.

Also see this in ALPHA at CERN. Eventually there are so many defunct elogd processes that the user runs out of "maxproc" quota and automatic submission 
of elog messages starts to fail. (and the users complain, reboot all computers, etc).

The elogd we use is this:
https://bitbucket.org/ritt/elog/commits/44800a769b99599db7620779e2142b1161c694fc?at=master

The best I can tell, the main elogd is spawning something but does not reap finished subprocesses (wait() syscall). My guess it is spawning ImageMagik stuff 
to create preview images.

Okey, found it. waitpid() in my_shell() is not protected against the periodic alarm signal. (UNIX signals are evil).

In the following log file, notice the entries that have "wait_status" of "-1". Those would have generated zombies ("defunct" processes).

Acknowledged. Thanks for the fix. I added it to the development branch.

i have been using elogbook V2.7.6 on my XP machine for a number of years. I ahve recently upgraded to windows 8 and the reply function on my entries has changed. I can now see the previous entrys in HTML format rather than the reply box which used to appear and also my ability to upload attachments and paste working linls is removed. Do i need to upgrade to the latest version and do i ned to back up my previous entries and how do i do this?

Thank you

Upgrading Windows should not change the behavior of ELOG, unless you made a mistake during re-installation of ELOG. Can you post a picture on how your reply looks like, it's hard for me to understand what you write.

/Stefan

 For the login to your email sever, the password is encoded in base64 form (actually not really secure). Somehow your server does not support this. Unfortunately I cannot test this without access to your server. But you can try yourself by doing a telnet to your mail server like:

$ telnet <server.domanin> 25

...

$ AUTH PLAIN

With the "plain" method, you should be able to enter your password in plain text (not base64 encoded), and see if that works. If you are successful, I can add this option to elog.

Best,

Stefan
