Test case (ripped out of eclipse{,-bugzilla}) (18.90 KB, text/plain)

no flags Details

Description Andrew Overholt 2006-01-23 16:50:05 UTC
Description of problem:
eclipse-bugzilla grabs the bugzilla components from the query page.  This fails
with gcc 4.1 where it does not fail with 4.0.x.  We isolated the parts that do
this (hackily and not very precisely, might I add ;) and I will attach that test
case.

Version-Release number of selected component (if applicable):
gcc-4.1.0-0.16.i386

How reproducible:
Always.

Steps to Reproduce:
1. javac FetchError.java
2. java FetchError
  
Actual results:
java.io.InterruptedIOException: Timeout while reading from input stream
   at FetchError$PollingInputStream.read (FetchError.java:402)
   at java.io.BufferedInputStream.refill (libgcj.so.7)
   at java.io.InputStreamReader.refill (libgcj.so.7)
   at java.io.InputStreamReader.read (libgcj.so.7)
   at java.io.BufferedReader.fill (libgcj.so.7)
   at java.io.BufferedReader.readLine (libgcj.so.7)
   at FetchError.getString (FetchError.java:580)
   at FetchError.main (FetchError.java:634)

Expected results:
No output (like gij 4.0.x and Sun).

Additional info:
(from Tom Tromey's comment in bug 178445):
"[the] test case fails -- it times out
when reading.  However, if I comment out the call to getTimedInputStream
(so that we're reading from the raw un-timed-out underlying input stream),
then it works.  I suspect that there is a timing bug of some kind
in the timed input stream code, but I have not looked into it deeply."

Comment 2 Tom Tromey 2006-01-26 00:34:38 UTC
I've checked in a fix for this to the 4.1 branch.
It is revision 110241.


Comment 3 Andrew Overholt 2006-02-06 20:01:03 UTC
I have verified this fix is in our rawhide gcc.  Thanks.
