I have been doing the Catalyst tutorial, at
https://metacpan.org/module/Catalyst::Manual::Tutorial
I am using the VMware virtual machine, as recommended. This is running in
VMware Fusion 5 Pro on a Mac. Overall it works perfectly fine, except that
periodically, I lose the ability to authenticate to the demo CRUD app (MyApp).
Based on observation, it seems that the only common factor is that it works
fine before my laptop is put to sleep for the night, and it is broken in the
morning. It doesn't seem to matter where in the tutorial I am. VMware, and
often the Catalyst app server, are running when the laptop goes to sleep.
(Arguably I should not do that, though the VM itself comes back just fine, and
the app server still responds, it's just that I am no longer able to
authenticate.)
Things I have tried already:
1. Move the ~/MyApp/ directory aside, remove /tmp/myapp (session data cache),
and run the server from e.g. ~/Final/Chapter05/MyApp. This results in the same
behavior (app server runs, and response to http requests, but when
authenticating, all I ever get is the "Empty username or password" error).
2. Reboot the VM
3. Reboot the Mac
4. Get to a working point, stop the app server, tar up ~/MyApp, and then next
time it breaks,
(stop app server)
cd ~
rm -rf ~/MyApp /tmp/myapp
(untar the copy of ~/MyApp)
cd ~/MyApp ; script/myapp_server -r
But that doesn't work, it exhibits the same behavior.
5. Delete ~/MyApp and /tmp/myapp and do the tutorial over again, pasting in all
of the code from the web page. (This is the only approach that has worked so
far, unfortunately.)
I am just learning Catalyst (obviously), so I don't have any good theories here
except that sleeping the VMware VM is corrupting something in its memory or
filesystem, causing the trouble. Memory would not seem to be a legitimate
suspect though, because rebooting the VM does not fix the problem. Whatever is
wrong is persisting across reboots, i.e. it's probably on the filesystem.
Does the tutorial cache data other than in /tmp/myapp? I have tried to find
other caches, but since I am running unprivileged, it seems as if it would not
be able to write outside of my home directory or /tmp, and I've already looked
in both of those. I don't see anything under ~/MyApp that appears to be dynamic
data, only in /tmp/myapp.
Thanks for any advice,
Dan
