Normally I'd say early August, some time in the first 2 weeks. But as we 
are entering vacation season it might slip. It largely depends on the 
release manager's availabaility.


I happen to be on vacation myself, but was still planning to do the 
8.5.70 release around the first of the month.


If neither Mark nor Rémy are available, I could attempt to do the 9.0.51

The fix will be in 9.0.51.

In terms of a workaround, switching from NIO to NIO2 should avoid the

Fix:  Expand the unit tests for HttpServlet.doHead()


Not an unreasonable guess but it looks to be an incorrect one.

I always recommend looking at the open bugs and the changelog from the 
CI system to see if the issue being observed has already been reported 
(and possibly fixed).


https://ci.apache.org/projects/tomcat/tomcat-9.0.x/docs/changelog.html

This looks much more like bug 65448 to me:
https://bz.apache.org/bugzilla/show_bug.cgi?id=65448




Any help?


The fix will be in 9.0.51.

Snapshots (NOT formal releases) are available for testing from:
https://repository.apache.org/content/groups/snapshots/org/apache/tomcat/tomcat/9.0-SNAPSHOT/

Usual caveats apply. These aren't releases. Use them entirely at your 
own risk.


In terms of a workaround, switching from NIO to NIO2 should avoid the issue.

Strange incomplete response/truncation with Tomcat 9.0.48 AND 9.0.50

2021-07-22 Thread jonmcalexander 
I have a team that is running into issues since version 9.0.48 where they are 
receiving incomplete message responses from Tomcat when the request was made 
from WebLogic. Here is the data I was provided:


it is breaking application files by truncating the files from source to 
destination which similar to our issue JS (javascript) file from App Server to 
App F5 to Web server. It is giving below error and it is working fine with 
9.0.46 when we revert and not working with 9.0.48/9.0.50 versions.


adrum.js:27 Error: Loading chunk 28 failed.

Network level we are seeing TCP Window Full intermittently when this file 
transfer.

We also have this information:
Detailed Problem:
Tomcat version 9.0.48 started to cause production issues in A and W apps (and 
possibly others).

After some additional research we assume this issue is related to one of the 
known bugs listed in RedHat TC release 
notes.
[Fix:] Expand the unit tests for HttpServlet.doHead() and correct the flushing 
of the response buffer. The buffer used to behave as if it was one byte smaller 
than the configured size. The buffer was flushed (and the response committed if 
required) when the buffer was full. The buffer is now flushed (and the response 
committed if required) if the buffer is full and there is more data to write.

As stated above, 9.0.46 appears to work, but .48 and .50 are both broke.

Any help?
