Re: Issue with Chunked Transfer Encoding in Tomcat 10.1.25-10.1.28 with Spring

2024-08-13 Thread Itzhak Fadida 
Thank you for your reply. I created a repository that demonstrates the issue.

https://github.com/tzahifadida/test-chunked

Currently it is set to 10.1.25 and fails. If you change it to 10.1.19
(in the pom.xml 10.1.19) it will
succeed. It should show 5 postings and not 1 in the output. The test
can be run with “mvn test”.
The output of the tcpdump is the same for both.

The success dump and output (you can see the deltas are greater than 0
indicating they were received one by one):

This version fixes a number of bugs found in previous releases.

Full details of these changes and new features,
are available in the Apache Tomcat Connectors changelog:

In addition to the usual source release, this release includes Windows
binaries for the JK ISAPI connector for IIS.

Thanks. That is very helpful.

git bisect has identified this commit:

https://github.com/apache/tomcat/commit/92e3c7a7adc574a859ab70333bf930561dcf1e9d

as the cause of the change in behaviour.

That makes sense as it is a change to the processing of chunked requests.

I need to debug this further to figure out what and where the root cause is.

Migration to Tomcat Assistance

2024-08-13 Thread Baez, Melvin L 
Hi all,

I'm reaching out to the community seeking assistance. I support Tomcat from an 
infrastructure perspective and assist our developers with migrating a set of 
existing applications from WebSphere and TomEE to Tomcat as the application web 
server.
We are trying to come up with a streamlined process of helping applications 
move to Tomcat, while accommodating their specific requirements.
I'm looking for utilities, scripts, cheatsheets that can assist us. Also, if 
there are other references of mapping libraries/jar files to features that 
would be helpful.

Thanks in advance!
