I am receiving a segfault whenever I attempt to upload a file.   Please see attached .txt for valgrind output.   This occurs in version elog-3.1.5-1.   I reverted back to version elog-3.1.4-3 and the segfault does not occur.

Segfault occurs in Elog version: elog-3.1.5-1

People are keeping me asking for a Windows installer. Is this now properly working, also under Windows 11? If you send me the executable, I could upload it to the distribution.

Do people have to install cygwin before they can use it, or will the executable runn just by itself? If I understand correctly, the MinGW package would not require a runtime library, right?

Best,
Stefan

Hi Stefan,

Some updates for Windows version.

I spent last WE to try to build ELOG on Windows from MSVCODE, MSCV, crosschain tool under linux etc, but in vain.

ELOG MSVC projects file are obsolete for last MS C++, and after migration, so much error or missing libs for SSL/Ldap/krb5 which should be built... I drop the sponge :-P

With mingw64 under Linux (docker/Debian), the code has also to be updated (C++11), but I don't get a build after all (also libs missing and must be built).

Finally, I can build Windows version from Windows with CygWin gcc-c++ as I did in the past. All the dependencies are available from CygWin installer. I got problems with strlcpy file missing, need to drop inlcude from elog.c and elogd.h as mxml doesn't include it anymore...

I find a Win64 CI/CD solution on AppVeyor which is free for OSS project. After creating account and add link to my ELOG test Bitbucket repo, ad new files (appveyor.yml, buildming script, update NSIS script for CygWin DDL, add tool for service), it builds automatically an elog-ver-release.exe artifact : (current build from GIT with SSL/LDAP/KRB5 available on month up to March 3, 2024 : https://ci.appveyor.com/api/buildjobs/logp7r8f0kcjq9pp/artifacts/elog-3.1.5-a720145.exe)

I installed this NSIS bundle on my PC and it's starting fine as a service.

NB: the AppVeyor build log enclosed, need some cleanup...

For Windows target, It's supported in Bitbucket but only with private agent :-(

So I tried to build using docker hub MSVC image (abrarov/msvc-2019) but pipeline fails to retrieve the image. Maybe I need to swipe on alternative images, or these images with MS software are unaccepted from Atlassian...

Also, I tried to crosscompiling ELOG Win32 from Linux with g++-mingw-w64-x86-64, but Makefile/sources need to be patched to manage this 'platform'... For the moment, it fails. :-(

Next solution : use Wine in Debian image to build Elog with mingwin as I know that it works (under Windows :-)). Will be tested after all...

For Windows it's more than just getting the .exe. Users want an installer. I used the Nullsoft Scriptable Installer (NSI), but I have no clue if this still works today. But there is still the elog.nsi script in the repository. Next, users want elogd as a service running in the background as a "service". I'm pretty sure the old way of doing that has changed and one would at least have to test this. Unfortunatley I switched to MacOSX about ten years ago (actually most of ELOG has been developed under Windows, but these days are gone), so I'm kind of illiterate in the Windows world now and don't have any time to change that.

What Stefan meant to say is that Elog does not implement sending email using encrypted SMTP over TLS.

In theory it could be implemented, but if you try to use it, you may find that most
destinations will reject you unless you have configured correct SPF records.

https://en.wikipedia.org/wiki/Sender_Policy_Framework

Even if you do everything right, joints like gmail may still reject you because
their AI decides you are a spammer, or just because they do not like you, and good
luck making them change their mind.

At TRIUMF, we configure elog to use unencrypted and unauthenticated SMTP
to smtp.triumf.ca, which has special rules to accept our email (no questions asked),
and our Microsoft email instance is configured to accept and forward email from
smpt.triumf.ca. Everything is done right, but we still see Fermilab's Microsoft
rejecting TRIUMF's Microsoft email once in a while.

Thanks,

Does email notification from a Gmail address work? It is noted that port 465 must be used for SSL use? Is this correct :


SMTP host : smtp.gmail.com

SMTP port = 465

SMTP username = monadresse@gmail.com

And, should I enter the password attached to my Gmail email and where?

Thanks in advance.

When using the Webserver authentication in combination with "File" and "Self register = 3", it is possible to keep track of registrations and control access still. This is very useful, and upon clicking on the logbook for the first time, the user is asked to register by typing their username, full name and email address.

First issue here is that they can still edit the box with their username, which might cause confusion if somebody decides to choose a different username and is then surprised about why they cannot automatically login again. Is it possible to lock this field from being edited?

The second issue is more minor, but the user has to manually type their name and email address, even though the webserver may already be able to provide this information in the headers. Specifically, it would be useful to read the name from the X-Forwarded-Name header and email address from the X-Forwarded-Email header. 

My config file snippet is below:

Authentication = Webserver, File
allow password change = 0
Password file = webserver.passwords
Self register    = 3

Dear All, 

 We have been using the ELOG for several years and had inserted hyper-links instead of whole files in order to save storage space. From this month our server is moved to a new location with a new address. Is there a way for me to retrospectivelly replace all addresses with the new server file pass?

Thanks in advance,
