MacOS dependency for circumvention for real time data dump unavailability on dmr-marc

[jcmurray]

The circumvention for the the real time data dump no longer being available on dmr-marc doesn't work on MacOS :-)

The defect

The following line was updated in db/Makefile in commit: ec7550dd0ed6300001026aff353e15536a629264

dmrmarc.tmp:
    timeout 120 wget --no-check-certificate --wait=3 'https://dmr-marc.net/static/users.csv' -O $@

Unfortunately there is no timeout command on MacOS so the Makefile bails when updating the database ( make updatedb ).

Possible circumventions I've thought of

• There is a MacOS equivalent called gtimeout which can be installed from Homebrew but that introduces a specific dependency into the Makefile which is not a happy thing :-(

• I had thought of using the following pattern

some_shell_command & sleep 5; kill $!

which achieves the same effect as timeout -- at least from a shell prompt. However, it doesn't work when executed as a Makefile recipe due to the way that Make launches the system commands in a rule :-(

• Use of on the various timeout options on wget to achieve the same effect?
• Remove the timeout command from the command line?

Just some thoughts. My own temporary 'fix' is to remove the timeout for the moment.

Is the MacOS wget the GNU wget? Actually, what I'm asking is, does it support the --timeout flag that GNU wget has? If so, that seems like the best option.

It's the GNU wget on MacOS if you use Home-brew to install/manage it.

@jcmurray I tested with a friend's macbook before pushing, so I believe this solves the problem. Thanks for the bug report and recommendations!

@mach327 git pull'ed the updated and checked it on my MacBook Pro. Works just fine now. Thanks!
