Hey, thanks for the report.
I wonder if this is the same issue as #40.
@cj - are you also on Snow Leopard?
@benkitzelman could you try dtruss on the process? i.e. dtruss rspec ... I am particularly interested in the output right before it hangs. You could also try using it on phantomjs too, to get a perspective from the other end of the socket - to do that set the :path config option to "dtruss phantomjs"
Thanks
from poltergeist.

I ran rspec spec/integration/driver_spec.rb:38 with dtruss and monitored the output...
At the point of hanging (when waiting for socket read) - dtruss for the poltergeist spec spits out this at regular intervals:
__semwait_signal(0x1403, 0x1603, 0x1) = -1 Err#60
... a bunch of these ....
__semwait_signal(0x1503, 0x1703, 0x1) = -1 Err#60

Poltergeist just sits and waits for phantomjs to send it something to read
from poltergeist.

Another question: did you install the phantomjs tarball, or did you compile phantomjs yourself? (perhaps via homebrew?)

Hi - sorry for the late reply - it was a standard homebrew install
from poltergeist.
jonleighton
commented on July 19, 2024
Ok, I think that's probably your issue. I believe homebrew compiles against Qt 4.7, which has an old version of WebKit and generally misses out on a bunch of patches that are supposed to be applied for PhantomJS to work correctly. Please try the binary package as detailed in the readme. (FWIW, PhantomJS 1.5 is imminent and doesn't compile against Qt at all any more - it has its own in-built, patched, version of Qt 4.8.)
