Issue 764: curl hangs when called from GetURLDataAsNSData() when HTTP port
needs proxy
http://code.google.com/p/gears/issues/detail?id=764
New issue report by foxden:
What steps will reproduce the problem?
1. Set up a network where Port 80 is blocked
2. Set up an HTTP proxy on some other port
3. Configure Mac OS X to use the proxy
4. Install Google Gears
5. Go to www.rememberthemilk.com
6. Sign in and turn on offline syncing
7. Watch Safari hang with a beachball
8. Force Quit Safari, and Mac OS X reports the following hang backtrace (I
filtered it through
c++filt for your pleasure).
The backtrace pretty clearly shows that Google Gears is blindly
running 'curl' without telling it
about the HTTP proxy set in System Preferences.

What is the expected output? What do you see instead?
I expect Safari not to hang when Google Gears is syncing. I expect Google
Gears to obey my user
settings for HTTP proxies.
One solution would be for Google Gears to set the 'http_proxy' environment
variable to the
correct value before calling curl. However, this won't work for SOCKS
proxies.
What version of the product are you using? On what operating system?
0.4.24.0, Mac OS X 10.5.5, Safari 3.1.2
