increase number of file descriptors allowed for couchbase server ( couchbase user ) for Mac installation

Farshid Ghods added a comment - 01/Oct/12 11:29 AM this explains why in linux we need sudo access when starting up the server but not on mac

Jens Alfke added a comment - 01/Oct/12 11:56 AM On OS X this is done with the setrlimit syscall, setting RLIMIT_NOFILE (which defaults to 256). The man page says:      Only the super-user may raise the maximum limits. Other users may only      alter rlim_cur within the range from 0 to rlim_max or (irreversibly)      lower rlim_max.      Because this information is stored in the per-process information, this      system call must be executed directly by the shell if it is to affect all      future processes created by the shell; limit is thus a built-in command      to csh(1) and ulimit is the sh(1) equivalent. This implies we need a privileged helper process that will raise the limit and then launch the server.

Jens Alfke added a comment - 01/Oct/12 2:24 PM There is no hard upper limit on RLIMIT_NOFILE, so a process can raise it to whatever it wants without needing root privileges. Sounds like the Mac shell app just needs to call setrlimit to bump this, before it launches the server.

Farshid Ghods added a comment - 01/Oct/12 2:44 PM adding this to the release notes. because 2.0 beta testers will notice that starting couchbase server now will require sudo-like privilege . i wonder whether a non-admin user on mac can still run the app

Jens Alfke added a comment - 01/Oct/12 2:45 PM It doesn't require privileges. See my above comment. There is no change in the user experience or requirements.

Farshid Ghods added a comment - 01/Oct/12 2:51 PM sorry missed the last comment. ( only read the first comment ) in that case this does not have to be documented.
