This is more robust, as it indicates the request was successfully
authenticated and processed, but that there is no data to export. This is
different from the URL not existing (which would also happen if the module was
unavailable, which should be a notable error instead).
Previously, the multi-stage build increased the image size by about 30
MiB (163MiB -> 191MiB). Dropping the caches reduces the image size down
to 159MiB, leading to a net improvement of 4 MiB.
Currently the Dockerfile has a single RUN directive with all the needed
commands in it. This optimizes for image size by not creating too many
"layers" (which are only additive). However it means the result that gets
cached can basically never be reused, because any change to the source code
will need to execute the whole RUN block again.
This commit switches to a docker "multi-stage" build, where we have a build
image that is separate from the final one that gets published. The build
image can be cached locally, and size is no longer a significant concern.
This approach allows the single RUN command to be split up into multiple RUN
commands that only execute when strictly needed (i.e. when their result
is not cached locally).
This drastically improves the build time when rebuilding the image after
a simple code change, because the build image doesn't have to install all
the apt packages, for example. This leads to a nicer developer experience
when using docker locally for development and testing.
wtforms 3.0 is incompatible with our code. A separate issue will be
filed to address the incompatibilities, but this should be enough to get
working images out of it.
With 3.x, we're seeing:
```
File "/home/horazont/Projects/python/snikket-web-portal/snikket_web/main.py", line 35, in LoginForm
address = wtforms.TextField(
AttributeError: module 'wtforms' has no attribute 'TextField'
```
and the portal fails to start.
Someone who registers via the web might also be interested in the web
portal.
Thanks to Jonas and Matthew for feedback on draft commit and help with
whatever this template syntax is.
Also no thanks to git for not actually having draft commits as a concept.
Mercurial is so much nicer to work with.
The button was broken because it was classified as popover, which
means that the JavaScript code will mess with it. In reality,
*that* button was supposed to point at the actual market:// URL.
So we just remove the class and associated data here to fix that.
Fixes#89.
This helps with removing those users from circles, to avoid them
popping up in peoples roster again.
Even though removal from a circle also only partially works
(roster entries are for instance not cleared), this helps with
ghost users reappearing all the time.
This is useful in situations where the admins of the Snikket
server (i.e. those who care for the docker containers) are not the
same people as the people who are admins of the Snikket service
(i.e. those who care for the users).
