Subject: Re: elogd crashes during Find and Mirror operations under MacOS 

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.)

The current GIT revision (c017d07) fixes the problem with the strlcpy() function (macOS 10.12.2, XCode 8.2). Can you try if that fixes your other problems, too?

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

git clone https://bitbucket.org/ritt/elog --recursive

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:

  __builtin___strlcpy_chk (dest, src, len, __darwin_obsz (dest))
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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
