Hot reloading not working on FreeBSD

[Matthew Faircliff]

• **aiohttp-devtools version: 0.8
• **aiohttp version: 3.0.7
• **python version: 3.6.4
• **Platform: FreeBSD 11.1

Issue Summary

After having followed the instructions several times using both virtualenv and pipenv I cannot get hot reloading to work. I had it working in a previous version about 6 months ago so am experienced in working with aiohttp as well as aiohttp-devtools. The server log states that it reloads the main.py file however any changes are only visible after stopping the server completely and then starting it again.

Steps to reproduce

virtualenv -p python3 venv36
cd venv36
source bin/activate
pip install aiohttp-devtools
adev start test1
cd test1
source ./activate-settings.sh
adev runserver test1 --host 192.168.0.1

It seems as though this is actually a aiohttp-jinja2 problem as the aiohttp code is reloading, however the templates are not. Am thinking it is the jinja2 enviroment setup using

aiohttp_jinja2.setup(app,
        loader=jinja2.FileSystemLoader(str(THIS_DIR / 'templates')),
        auto_reload=True,
        cache_size=0,
)

Although I am still struggling to get this to work.

Closing this as it is not a devtools issue. Any comments would however be appreciated.

I've never had a problem with jinja templates reloading, in my experience they generally "just work ™️", however BSD based systems are very rarely used so it's possible there's a problem there.

I was having a problem with aiohttp-devtools (not using jinja templates) reloading yesterday on ubuntu which I'll look into more when I get the time.

Hi Samuel,

Thanks for your feedback.

I have done a clean reinstall of the entire OS with latest FreeBSD. Used pipenv to install aiohttp-devtools and aiohttp (all latest). I can confirm that there is indeed still a problem: the main.py (which includes create_app()) reloads content on changes however the views.py files does not (even though the adev does restart). The views.py contains some jinja2 templates but even if I remove these and return plain web.response the response is not updated on reload.

Quite strange as I have aiohttp-devtools running 100% ok on a system I installed at the beginning of last year. I copied the requirements.txt from this machine and installed into new pipenv venv and everything works as expected. There is something wrong somewhere.

I found this too. It's fixed by #181. I will release that today.

[Matthew Faircliff]

Thanks. Thought I was going crazy for a while there. Glad I could help.

[Samuel Colvin]

should be fixed by v0.9 release which should be running now. Sorry about the delay in releasing.

Please let me know if you still have a problem.
