Re: [Zope] Zope 4 migration
Hello Michael, thanks. I'll install Products.TemporaryFolder to avoid the warnings but will replace /temp_folder with a normal folder as recommended by the maintainers of the Sessions product. Now let's see how the more complicated setups cope with Zope 4 - LOL.

You could also configure an additional ZODB for the server side session data and mount it instead of using Products.TemporaryFolder. This makes server side sessions persistent between restarts. > Also, for me this means installing 8 Products after installing Zope with pip: > Sessions, ExternalMethod, PythonScripts, ZSQLMethods, ZMySQLDA, MailHost, > TemporaryFolder, SiteErrorLog.

Thank you very much for your help. I have some reservations about installing Products.TemporaryFolder. See here: https://pypi.org/project/Products.Sessions/ "The default session support under Zope 2 relied on Products.TemporaryFolder for storing session data, which in turn used the tempstorage package. tempstorage is no longer recommended because it has unfixed and possibly unfixable issues under Zope 4 that lead to corrupted temporary storages."

Would the standard zc.buildout install already contain some of those?

When using plain Zope Ctrl-C on the command line should be enough. There is no button in the UI any more because the web server is no longer part of Zope itself. Instead you are able to use a WSGI server of your choice.

Re: [Zope] Zope 4 migration
Hi Michael, we are all in the same boat with migrating old projects. Although there is some pain, I am very happy that Zope is kept alive. Imagine you had to rewrite all Zope based applications from scratch. There was an enormous effort from both the Zope and the Plone community to port it to Python 3. In Python 2 you would use the `virtualenv` command to create a virtual environment https://virtualenv.pypa.io/en/latest/ And yes, you can deploy Zope on Python 2 with buildout - that's how I run my app currently. >I managed to install Zope 4 using pip and get an instance running with >runwsgi. Now I am wondering how to stop it? How am I supposed to stop a >running instance? There seems to be no command and no option in the GUI. So, how did you start Zope? As an advice - this list ist extremely low traffic, and I do not know how many Zope developers still read it. There are two places where you usually get answers: Either visit the Plone forum https://community.plone.org/ -> tag your question with "Zope" or directly ask a question at github, for Zope e.g. https://github.com/zopefoundation/Zope or concerning your other question about zodbupdate at https://github.com/zopefoundation/zodbupdate I'd go for the community forum first (except you think you found a bug).

Re: [Zope] Zope 4 migration
