1744 - NGLayout hangs forever on nsIURL::Read() if file is empty

Status: VERIFIED DUPLICATE of bug 1742

(Core :: Networking: File, defect, P2)

Description

[jst]

nsIURL *url;

NS_NewURL(url, "file://C:/foo.bar");

url->Open(...)

url->Read(...)

hangs on Read() if the file C:\foo.bar exists but is empty. I tried looking into
this but I didn't see any obvous errors, I did notice one thing though, the
nsIURL::Read(...) hangs on

  PR_Wait(m_Lock, PR_INTERVAL_NO_TIMEOUT); (nsNetStream.cpp:713)

and the netlibrary does

  LIBNET_UNLOCK_AND_RETURN(XP_ListIsEmpty(net_EntryList) ? 0 : 1);

from what I could se the address of the m_Lock and the lock that is unlocked is
not the same!. I do not know if this information is important or even correct...

confirmed that it doesn't hang forever on a document that has no data. A good
test, I will put it in my test cases.

Changing all Networking Library/Browser bugs to Networking-Core component for
Browser.

Occasionally, Bugzilla will burp and cause Verified bugs to reopen when I do
this in a bulk change.  If this happens, I will fix. ;-)

Bulk move of all Networking-Core (to be deleted component) bugs to new
Networking component.
