Re: broken http response when deployed on OpenShift

Also, you have the option to rebuild RPM from SRPMS or SOURCES via ELOG buildrpm script.

You will need to install rpmbuild tools...

Options (ldap, kb5, etc) can be set from options or by editing defaults.

Enrico,

When using RPM in OpenShift, I guess all the RPM dependencies are correctly installed.

FYI, I met a problem with elogd docker built with alpine Linux image and running on Synology NAS (x86_64). The ImageMagick dependencies libs provided by alpine for X86_64 are optimized for better CPU than mine with AVX2 (or something like that), and elogd failed to save a log with any enclosure (core exit, bad instruction), as some thumbnails are generated while saving.

As I didn't find any easy workaround w/o rebuilding all IM libs, so I switch to Debian images more conservative in CPU optimization, but bigger :-( before to switch to minideb that's run fine in my case.

It's not easy to debug in container w/o making one specially for that, so you should try to build a docker based on alma9 image, compiling elogd from sources (you can follow https://github.com/loll31/elog-ldap for the process).

Good luck

NB : The ldd result from my minideb Docker :

Hey Enrico,

Do you activate also all options with your build ? (pam/ldap/kb5/ssl)

Can you compare ldd command results on elogd binaries builded by yourself and the one from RPM ?

$ ldd /path/to/elogd

Also, size of both elogd files.

Regards

Enrico Gamberini wrote:

Sorry for posting again but something else came up.

Actually, building from source (elog-3.1.5-1.tar.gz) works just fine on OpenShift too.

The problem described below only happens when installing the packaged binary elog-3.1.5-20240226.el9.x86_64.rpm.

Hello!

We're setting up ELOG on OpenShift. ELOG is installed on a Alma Linux 9 image. The container and the elog demo works fine executing the docker image locally.

When deployed on OpenShift, we get a weird response, that results in a 502 Bad Gateway. The broken response looks like:

# curl -v -H 'X-Forwarded-User: enrico.gamberini@cern.ch' https://psi-elog-container2-elisa-epdtdi.app.cern.ch/demo/

Notice the HTML tag before the HTTP header, as well the duplicate HTTP header.

I understand that it might be difficult to reproduce, but any input would be very welcome!

Re: Entry size too large for email notification

Wouldn't it make sense for ELog (by default) to still notify, but not send the attachments by e-mail if the size limit is reached?

Andreas Luedeke wrote:

Hi Jacky,

if I read the source code correctly then the maximum size of a base64 encoded email is hard coded to be 10 MB in elogd.h (recompile after changing it):

#define MAX_CONTENT_LENGTH 10*1024*1024

But I think that an 2.2 MB image should easily fit into that.

Hi,

I am doing an inline image that is about 2.2 MB. When I do a submit, I got the following message:

Error sending Email via <i>"<email server>"</i>: Entry size too large for email notification.

May I know what is the limit of the entry size and how do I change it? Thank you.

I'm asking! :-)

I have a few Extendable Options attributes, and it would be extremely nice if they got sorted as users put them 
in. So that when you select the drop-down box, alle options are sorted.
