From Bugzilla Helper: User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-us) AppleWebKit/125.5.6 (KHTML, like Gecko) Safari/125.12 Description of problem: If you have an expect script that produces large amounts of output the output 'sticks' and repeats at some point. This seems to be the same behavior described in bug #147276 but I observe it in any terminal. [jennings@weimar ~]$ expect expect1.1> spawn perl spawn perl 13403 expect1.2> interact print $i++,"\n" while (1) <ctrl-D> Version-Release number of selected component (if applicable): expect-5.42.1-1 How reproducible: Always Steps to Reproduce: 1. see above 2. 3. Actual Results: The output gets to about 10000 and starts to repeat. Expected Results: The output should count upwards until you stop it Additional info:
I see this is an old bug report. I just recently took ownership of the expect package, so I'm trying to get caught up. Two things: 1) I can't do anything for FC3 as that's now unsupported. 2) On rawhide (what will become FC5), I ran your test above and the problem doesn't appear for me. I let it run to 509003 and killed it. Rawhide has expect-5.43. If you're running FC5 Test 2 or rawhide, can you confirm the behavior is fixed?
Yes, it was fixed in a later version
OK, thanks.
