  66007   Fri Oct 17 20:40:39 2008 Question Barendb.vandevrande@amtc2.comQuestionWindows2.7.5-2130Standard login Screen - bottom text

Hi Stefan.

I have been "playing" around with this great tool and found an interesting "issue" ...

I use multiple logbooks and have both "Protect Selection page = 1" and "Expand Selection Page = 1".

When I open my elog, I get a Standard Login Screen with the Standard Bottom Text "ELOG V2.7.5-2130" which will link to your this website.

When I "Logout" and "Login" again from the Logbook page, I get another Login Screen with my own "Bottom text login" which will link to my own elog page.

How can I apply my own Bottom Text to the Standard Login Screen ?

Thanks & Regards, Barend

 By using the configuration option "Bottom Text Login = ..."

Stefan,

I have defined the "Bottom Text Login = ..." in each Logbook Configuration section. But when I use this option in the Global Section, ELOG fails to start.

 That's strange. I just tried myself following configuration file:

[global]
port = 8080
Bottom text = 
Hello
Bottom text login =
Login Hello
Password file = passwd [demo1] Comment = General linux tips & tricks Attributes = Author, Type, Category, Subject Options Type = Routine, Software Installation, Problem Fixed, Configuration, Other Page Title = ELOG - $subject [demo2] Comment = General linux tips & tricks Attributes = Author, Type, Category, Subject

and everything works fine as can be seen from the login screen:

Capture.jpg

so can you check if above file works for you?

 Hi Stefan,

Hope you have enjoyed the Christmas week.

Sorry for the delay.... I have tested your configuration and it worked for me as well. 

In order to determine, which of my settings is causing the problem, I had to activate each individual entry "one by one" and check if the error re-occured. I finally identified following entry "Protect Selection page = 1"

The error also occurs if I change your configuration into:

[global]
port = 8080
Bottom text = <center>Hello</center>
Bottom text login = <center>Login Hello</center>
Password file = passwd
Protect Selection page = 1

[demo1]
Comment = General linux tips & tricks
Attributes = Author, Type, Category, Subject
Options Type = Routine, Software Installation, Problem Fixed, Configuration, Other
Page Title = ELOG - $subject

[demo2]
Comment = General linux tips & tricks
Attributes = Author, Type, Category, Subject
 

Can you advise if I'm missing an entry in order for "Protect Selection page = 1" to work?

 

"Schönen Rutsch ins neue Jahr".

Regards, 

Barend

When installing ELOG 3.1.2 on my Mac Sierra (10.12.2) with the latest XCode 8.2.1, it seemed to install fine but for one warning when building elogd:

cc -O3 -funroll-loops -fomit-frame-pointer -W -Wall -Wno-deprecated-declarations -DHAVE_SSL -I /opt/local/include -o elogd

1 warning generated.

My installation was done with "sudo make install", as the instructions state.  I have also been using the prescribed "launchctl" approach.

1. Is the above warning something that needs attention/correcting?

2. My elogd crashes now every time that I attempt any kind of "Find" operation.

3. I synchronize my MacOS version of elog with a linux-based version on my university's web server.  I have installed 3.1.2 on the linux server, and it is running there without problems.  When I now try to synchronize my 3.1.2 ELOG on MacOS laptop with the same version on my linux server, it appears to do the first mirroring operation correctly, but elogd crashes when I try a second synchronization at a later time.  (For now, I have "Mirror simulate = 1" to prevent inadvertent damage.)

Can anyone help me with the above points?

Thank you,

Andreas

Plese remember to use the recursive clone to get that version:

Thank you very much (both Andreas and Stefan)!  The build now runs without warnings, and I am now able to do Find operations without crashes.  I still am having some issues with the synchronization, but I suspect that this is elog-content related, so will in the coming days do some more testing from CERN (where I have higher bandwidth with my home institution in Canada).  Incidentally, I had to add a line to Makefile in order to be able to build on my Mac.  See below, in case you want to update the Mac Makefile for others.

Many thanks again,

Andreas

ifdef USE_SSL

ifneq ($(USE_SSL),0)

CFLAGS += -DHAVE_SSL

CFLAGS += -I /opt/local/include

LIBS += -lssl

endif

endif

(You may wish to update the distribution if you think it may benefit other Mac users.)

  68539   Mon Jan 9 17:15:56 2017 Question Andreas Warburtonawarburt@physics.mcgill.caBug reportMac OSXV3.1.2-edc5e85elogd crashes during SSL Mirror operations involving attachments

My MacOS (10.12.2) elogd version V3.1.2 is a recent git commit (edc5e85), due to the fix to my earlier-described issue solved in the thread here: https://midas.psi.ch/elogs/Forum/68519.

I am trying to (re-)set up Mirror functionality with a linux server running the standard public (V3.1.2-bd75964).  I had initially updated the linux server so that it also had the latest git commit (edc5e85), but could then not even add new logbook entries that involved attachments to it.  I therefore rolled the linux server back to the standard public 3.1.2 version.

On the remote Mac, synchronizations usually look like they are going to work fine, with Mirror simulate = 1 switched on.  After I set Mirror simulate = 0, and if the server and remote logbook are already identical, I *occasionally* get the proper "All Entries Identical" synchronization result.  Unfortunately, this is very rare, and usually there is a failure whereby the remote (Mac) logbook decides that a significant fraction of its entries (usually sequential, from some seemingly random entry all the way up to the last entry) are missing on the linux server and need to be submitted back to the server from the remote Mac.

When the local and remote logbooks are not identical, and a record in need of synchronization contains an attachment, there is again destructive behaviour similar to that described above, except that the Mac elogd executable usually crashes.  (As in the case of the already-identical synchronizations described above, I only tested this after observing the correct expected behaviour first with Mirror simulate = 1.)

I'd be grateful for some help/suggestions.  My current testing suggests that my problems are likely not elog-content dependent.  (The logbook now undergoing synching has less than 10 entries in it.)

More generally, the issue of having things behave fine with Mirror simulate = 1, but then experiencing corruption/damage when switching to Mirror simulate = 0 seems serious to me.

Many thanks, Andreas

 
  68547   Fri Jan 13 08:27:15 2017 Entry Andreas Warburtonawarburt@physics.mcgill.caBug reportLinux | Mac OSXV3.1.2-edc5e85Re: elogd crashes during SSL Mirror operations involving attachments

The attached screenshot shows the behaviour after doing a synchronization (with Mirror simulate = 1) following first having ensured that the local (Mac) and remote (linux) ELOGs initially showed "All entries identical" when doing a simulated synchronization, and then having edited local entries 9707 and 9709 by uploading (different) attachments to them.

The fact that the synchronization is suggesting to renumber two different entry IDs to the same number looks like a bug.

Best regards,

Andreas W.
