Re: How to start Rev by shell or startup item in the background under Mac OS X

Brian,
Pierre,
If you just need access to port < 1024, I believe it's possible to 
make root the owner of the application and have access from a GUI 
app... but I doubt the app will run without Cocoa.
Me too and it's all the problem : i don't want GUI at all... The Linux 
issues of my Rev apps servers are running lots faster than the Cocoa 
GUI binded ones and i suspect that they would be able to run lots 
faster under the Darwin platform too in the unix deamon mode. If that 
can be done, i will just switch back to linux, in about server-side 
stuffs...
I don't think anything other than the Darwin/CGI engine will run on 
MacOSX if you cannot have Cocoa or XWindows. A while back I talked to 
Tuviah about a custom Darwin engine with database external embedded 
and a fork() command for this specific task but I ended up going a 
different route.
...
I'd say your best (and only other option on MacOS) is to use the 
Darwin engine. Note that this is not just for CGIs - it can open 
regular stacks under XWindows. Maybe you could have some sort of 
XWindows stub libraries installed, or set the DISPLAY to something 
null. If you could suppress XWindows, it would probably work.
Never tested Darwin for yet but, as you say, it's a good time to see if 
this solution would work.

Many thanks for your helpfull input :-)
Best Regards,
- Brian
Unfortunaly, this don't feet the need to be able to start the process 
in root protected mode with access to a socket port < 1024. In more 
detailled words, is it a way to start a rev application from the 
Darwin shell console even if none of Cocoa nor XWindows are launched 
(darwin single user console mode start up) ?

Hi Todd,
Hi,
Keep in mind that with Tiger (10.4), Apple is providing a new method 
to start  daemons, and other background services -launchd.  It is part 
of the both the client and server.  I would imagine that if you were 
deploying your app on 10.3 or lower you could package it up just like 
you do for linux.  But 10.4 on up it looks like launchd is the way to 
go.

From Apple's website:
launchd provides faster startup through a unified framework for 
starting, stopping and managing daemons, and incorporates inetd, init, 
mach_init, System Starter and related services. Administrators have a 
single mechanism for auditing, configuring and setting resources 
limits on services.
Many thanks for this very interesting alert. Will go to the ADC docs to 
see closely what Apple is proposing in this way to (try to ?) become as 
confortable as others unixes are in about those kind of tasks ;-)

Best,
Pierre

Todd

Hi Frank,

Theoretically, you could use the rc scripts in the /etc directory to 
start your app; however, there is an issue with this, where upgrades 
to the OS can and sometimes do replace these files without asking for 
permission.
Yeah ! And it's why we have time to time to reinstall or tune some 
.conf files (Apache, Postgres,..).
These files are the 'normal' way to do it with most *NIX platforms, 
but Apple warns you *not* to use them for OS X.

The "correct" way to do this with Mac OS X is to place things in 
/Library/StartupItems.

For more details on how to write StartupItems, see this page:
http://www.macdevcenter.com/pub/a/mac/2003/10/21/startup.html
Thanks. Will try those ways. No knowed issues with Rev 2.5.1 it self, 
in about this kind of configs ?
StartupItems are launched after the GUI is started, but before the 
login window appears (or the user is logged in automatically, if the 
machine is insecurely configured to not display a login window).  They 
are indeed run as root, and are not supposed to be graphical in nature 
(they should be faceless background processes -- what UNIX calls 
daemons and Windows calls "services"...
Thanks again,
Best Regards,
Pierre

Pierre,
If you just want to launch an ordinary MacOSX Rev standalone on 
startup, you can put it in:

/System/Library/StartupItems/
You could also put an AppleScript in here to perform all sorts of 
actions.

Along with Ken's tip, you could hide the GUI and make it a 
background process- although sometimes it is actually nice to have 
an admin interface visible.
