tutorial deployment fails

[metaperl]

The deployment tutorial

first fails because reahl.mailutil is not provided. I think I can fix this by adding a new dep and re-uploading.

The next reason for failure is:

reahl.component.config.ConfigurationException: mail.smtp_port in /home/schemelab/etc/mailutil.config.py is using a dangerous default setting: 8025

I'm tracking down why it thinks port 8025 is dangerous.

[metaperl]

The reported directory for mailutil.config.py (/home/schemelab/etc/mailutil.config.py) is incorrect - there is no such file in ~/etc/ on my pythonanywhere virtual machine.

Removing the strict_validation check in reahl/component/config.py allows the default application to serve - http://schemelab.pythonanywhere.com/

But there are some TODO ITEMS HERE:

1. reahl-mailutil should have been a part of the project file
2. the reported directory for the configuration file is incorrect.

Until these are fixed, please do not close this.

[metaperl]

How do you configure the mailport to avoid this error. Specifically:

1. what port to use?
2. what file to configure this in
3. what exact syntax to use in that file to configure it.

[IwanVosloo]

Ok, the file it reports is the correct filename even though it is not there. It assumes default settings when the file is not there, or when the specific setting is not set in the file.

So, to fix, you just need to create the config file and specify that setting.

It thinks 8025 is dangerous because that is the default value and it is a default chosen for use in development, normally you'd use 25 in prod. But what you decide to set it to does not matter at all. It will shut up if you just give it any value.

The exact syntax would be:
mail.smtp_port = 8025
(or any number you want...with the assumption an smtp server is listening on that port)

I forgot - we made it actually break instead of just giving a warning when it determines that you are in production.

[IwanVosloo]

There are issues now to deal with what came out of this, but I am leaving this issue here (and marking it as a bug) so that reahl-mailutil can be added to that example.

[craig-reahl]

The problem is not with the deployment examples. The problem is that reahl.web.ui imports RestructuredText from reahl.mailutil

Either add a runtime dependency or move the ReStructuredText class elsewhere (reahl.component?)

[IwanVosloo]

Ok, I get it, so we need to add a dependency from reahl-web to reahl-mailutil...
