Hi Stefan,

Just incase it helps, I am attaching the file for an entry in our demo logbook.  If I edit this entry and click on submit (without checking "suppress email notification"), I get the seg fault shown below.

If I delete any single character from the entry, I do not see any problems.  If I re-insert a character anywhere, the problem returns.

I hope this is useful.  

Thanks again,
Devin

Indeed, uploading images over a satellite connection does not crash the development ELOG server available from SVN.  Our user was unable to 
crash 
elogd (or upload an image) and reports "The upload window would complain about an "upstream server", but the site was still there."

Thank you very much for your time and help (with both of the issues reported in this thread).

Sincerely,
Devin

I'm not sure if this is the expected behavior, but it appears as though an attachment is not displayed in the list of attachments if you manually add a link to the attachment into the body of the entry.  I would greatly appreciate any advice on how to fix or change this behavior.

I will try to demonstrate with the two attachments on this entry.  There are two attachments in this entry, but only one appears in the standard view of the entry.

Hi, Stefan.  When someone using a satellite connection tries to upload an attachment *or* edit a long entry, it fails and they are presented
with an "Internal Server Error."  This is a huge improvement over the previous behavior of crashing elogd, but we were wondering if there is any
hope of improving this further so that one can edit large entries or upload attachments over a slow (in this case, satellite) connection.  Do
you have any ideas or plans on working on this further?  Apparently ELOG is the "only" service this user has trouble with from  home.

Any information you could provide would be greatly appreciated.

Many thanks,
Devin

For heightened security, we allow access to our ELOG installation from offsite through an apache proxy.  Therefore, the URL for our ELOG becomes http://www.lepp.cornell.edu/proxy/elog/ .  Everything seems to work properly with this setup except for the "reset password" utility.  When trying to reset ones password, the link sent in the "Password recovery" email becomes, for example:

http://www.lepp.cornell.edu/proxy/elog/ERL+W128/?redir=%3Fcmd%3DChange+password...

When using this link, the redirect redirects you to:

http://www.lepp.cornell.edu/ERL+W128/?cmd=Change%20password...

Which does not work.  Instead, the redirect should point to:

http://www.lepp.cornell.edu/proxy/elog/ERL+W128/?cmd=Change%20password...

Hi, All.  We have been successfully using ELOG in a limited deployment for a couple years now.  However, we are about to embark on a new project that could run for up to 10 years, and are wondering what sort of scalability we can expect from ELOG.

Are there any problems we can expect to run into as the number of entries grow?  I see in a previous thread that "elog runs fine for a few 10000 entries. At 100000 entries it starts getting slow."  Is this still the case, or have any improvements been made?  What sort of problems would we expect to run into?  Any examples of existing large deployments would be very useful.

Many thanks,

Devin 

Hello,

We are now running elog-2.7.5 in a Scientific Linux 4 (RHEL4) system, which uses ImageMagick 6.0.7.1.  After uploading an image, the image 
manipulation buttons don't work and complain:
convert: unrecognized option '-set'

We are using an RPM built from source, and it looks like I should be able to just change "-set comment ..." to "-comment" as in:
------
[dab66@lnx100 tmp]% diff elogd.c elogd.c.new 
22601c22601
<       sprintf(cmd, "convert '%s' -rotate %d -thumbnail %d -set comment ' %d' '%s'", file_name, new_rot,
---
>       sprintf(cmd, "convert '%s' -rotate %d -thumbnail %d -comment ' %d' '%s'", file_name, new_rot,
22607c22607
<       sprintf(cmd, "convert '%s' -rotate %d -thumbnail %d -set comment ' %d' '%s'", file_name, new_rot,
---
>       sprintf(cmd, "convert '%s' -rotate %d -thumbnail %d -comment ' %d' '%s'", file_name, new_rot,
22618c22618
<       sprintf(cmd, "convert '%s' -rotate %d -thumbnail %d -set comment ' %d' '%s'", file_name, cur_rot,
---
>       sprintf(cmd, "convert '%s' -rotate %d -thumbnail %d -comment ' %d' '%s'", file_name, cur_rot,
22624c22624
<       sprintf(cmd, "convert '%s' -rotate %d -thumbnail %d -set comment ' %d' '%s'", file_name, cur_rot,
---
>       sprintf(cmd, "convert '%s' -rotate %d -thumbnail %d -comment ' %d' '%s'", file_name, cur_rot,
------

Is there any better way for us to fix this, or is anything else needed?

Thanks,
Devin

Hi, All.  Ever since upgrading from an old ELOG release on an aging windows machine to the latest version on Scientific Linux 4 (RHEL4), and 
greatly increasing its use, we have seen frequent crashes of elogd.  This has become very disruptive to operations, and any help would be greatly 
appreciated.  We are using Apache (running on the same machine as elogd) to secure ELOG using https as per the Administrator's Guide.

Anecdotally, the crashes seem to frequently happen when a user is attaching an image.  However, most of the time attachments succeed without 
incident.

I attempted to obtain a stack trace by attaching gdb to the process, but elogd died during the night.  It was urgently needed, so I needed to kill 
the elogd process (ptrace() kept it hanging around) and therefore could not obtain a stack trace.  For what it's worth, here is the output we do see in 
gdb:

I plan on letting elogd create a core dump, but so far I haven't managed to change its cwd to a directory elog can write to.

Please let me know if there is any other information I can provide.  Any suggestions would be greatly appreciated.

Many thanks,
Devin
