Don't clutter up our RDoc/website with things that users
of Unicorn don't need to see. This should make user-relevant
documentation easier to find, especially since Unicorn is
NOT intended to be an API.
|

These nasty hacks were breaking Rubinius compatibility.
This can be further cleaned up, too.
|
|
This was accidentally enabled when ready_pipe was developed.
While re-daemonizing appears harmless in most cases this makes
detecting backed-out upgrades from the original master process
impossible.
|
|
No point in having namespaces be classes when we never
create instances of them...
|
|
Since we added support for the "working_directory" parameter, it
often became unclear where/when certain paths would be bound.
There are some extremely nasty dependencies and ordering issues
when doing this. It's all pretty fragile, but works for now
and we even have a full integration test to keep it working.
I plan on cleaning this up 2.x.x to be less offensive to look
at (Rainbows! and Zbatery are a bit tied to this at the moment).
Thanks to Pierre Baillet for reporting this.

Rainbows! and Zbatery have long been upgraded to
pass options to us.

Inspection of the MRI source reveals that IO#sync=true only
appears to only apply for writes. Though it could eventually
make sense to disable read buffering by setting IO#sync=true,
it does not appear to happen.
Of course we never read from $stdin anyways....
|
|
Rainbows! does not yet know about ready_pipe, and will probably
not know about it until Unicorn 0.97.0
|

Rather than erroring out with a non-descript EOFError,
show a warning message telling users to check the logs
instead.

Otherwise the original spawner process may not notice the close
as it's still being shared by workers. While we're at it, avoid
confusing the original spawner by using readpartial instead of
sysread.
|
|
This behavior change also means our grandparent (launched
from a controlling terminal or script) will wait until
the master process is ready before returning.
Thanks to Iñaki Baz Castillo for the initial implementations
and inspiration.

This ensures any string literals that pop up in *our* code will
just be a bag of bytes. This shouldn't affect/fix/break
existing apps in most cases, but most constants will always have
the "correct" encoding (none!) to be consistent with HTTP/socket
expectations. Since this comment affects things only on a
per-source basis, it won't affect existing apps with the
exception of strings we pass to the Rack application.
This will eventually allow us to get rid of that Unicorn::Z
constant, too.

|
Otherwise errors in the Unicorn-specific config files can get
error messages swallowed up when daemonizing.
|
|
The daemonization logic between unicorn and unicorn_rails
scripts can definitely be shared.
Again: our daemonization logic is slightly non-standard since
our executables are designed to run in APP_ROOT/RAILS_ROOT and
not "/" like "normal" UNIX daemons.
