This mailing list is to discuss the nerdy programming development of Dada Mail -

If you are just looking for support Dada Mail, consult the message boards at:


To post to this list, send a message to:


All subscribers of this list may post to the list itself.

Some on topic... topics include:

  • Positive Crits on the program (I like, "x", but, "y" needs some work - here's an idea on how to make this better...)
  • Bug/Error reports
  • Bug fixes
  • Request For Comments on any changes to the program
  • Help customizing Dada Mail for your own internal needs
  • Patches
  • Language Translations
  • Support Documentation/Doc editing, FAQ's, etc.
  • Discussion of any changes that you would like to be committed to the next version of Dada Mail -

At the moment, there aren't many people with CVS access for Dada Mail - if you would like CVS access, please first talk about the changes you propose and how it will affect the program. If the idea is sound and agreed upon, the change will be comitted. A good track record of this will allow you to have CVS access. Some reasons that patches will not be accepted is if the patch breaks compatibility with a previous version of the program, the patch is too centric to your own problem or the patch simply isn't very good.

Please, please please familiarize yourself with the documentation at:


Since no one wants to answer the same question twice.

Another sneaky reason for this mailing list is to test out the discussion list capabilities of Dada Mail, since Dada Mail is used for the mailing list itself.

NOTE - because of this, there may be times that this list will be somewhat broken. Although we're not planning on breaking the program by using it, we're giving you the heads up that this may well happen anyways.

Re: Curbing semaphore messages

November 5th 2019

Justin, Sorry for the delay in replying. No, the semaphore error message does not occur if the scheduled jobs are run from the admin page. As far as I could tell, no lock files were being written to .tmp when the Schedule::Cron jobs ran. Thanks for the assistance in identifying the warning in the code.I have modified the warning, retaining the part to the process ID number and the last part with the code line number. This shorter message is a useful 'heartbeat' signal, in these early days of my ...Continue Reading

Re: Curbing semaphore messages

November 3rd 2019

Hmm - do you get the same error, (Semaphore does not exist to delete), if you run the Schedule Jobs URL, just in your browser? Does that file, (/home/very/long/path/user/private/.dada_files/.tmp/scheduledtasks.lock) actually exist? I guess if you want a bodge, you could just remove the line that throws that warning, Look for: warn "PID: $$ Semaphore does not exist to delete at, '" . $self->lockfile; in, dada/DADA/App/ScheduledTasks.pm and just remove it, Cheers, ...Continue Reading

Re: Curbing semaphore messages

November 3rd 2019

Justin, thank you for your reply and thank you for developing Dada Mail and making it available. The script for running Schedule::Cron is very simple and based on one of the examples supplied with Schedule::Cron. It's located in cgi-bin alongside dada and started with my SSH shell. So that it keeps going when I exit the shell, I use nohup with an ampersand to keep it in the background. So far, it's kept running. Dada Mail is run by Schedule::Cron using the precise curl command Dada Mail proposes ...Continue Reading

Curbing semaphore messages

November 2nd 2019

Hello Developers, I have just joined the list. Over the past couple of weeks, I have installed Dada Mail on the shared host of the website of the astronomy society I am involved in, to provide a discussion list.This was not without challenges (ssh cli install only, no CPAN,additional Perl modules for SSL built locally and uploaded, etc) but it is almost ready now for society members' use. Cron and crontab were also unavailable on the shared host, so I have made and uploaded Schedule::Cron, a cro ...Continue Reading
