After having installed python3-locust, I have this issue :
```
Traceback (most recent call last):
File "/home/sebastien/.local/bin/locust", line 5, in <module>
from locust.main import main
File "/usr/lib/python3/dist-packages/locust/__init__.py", line 18, in <module>
from .contrib.fasthttp import FastHttpUser
File "/usr/lib/python3/dist-packages/locust/contrib/fasthttp.py", line 23, in <module>
from charset_normalizer import detect
ModuleNotFoundError: No module named 'charset_normalizer'
```
After installation of python3-charset-normalizer, the executable locust works perfectly.
I use Ubuntu noble 24.04LTS.
Here are the versions of packages during installation :
15-python3-locust_2.24.0-1_all.deb
python3-charset-normalizer_3.3.2-1_all.deb
Have a nice day. |
[ Impact ]
locust fails to run and crashes immediately when executed by the user.
$ locust --help
Traceback (most recent call last):
File "/usr/bin/locust", line 5, in <module>
from locust.main import main
File "/usr/lib/python3/dist-packages/locust/__init__.py", line 18, in <module>
from .contrib.fasthttp import FastHttpUser
File "/usr/lib/python3/dist-packages/locust/contrib/fasthttp.py", line 23, in <module>
from charset_normalizer import detect
ModuleNotFoundError: No module named 'charset_normalizer'
[ Test Plan ]
install locust.
As a basic test, execute "locust --help"
If the package is not fixed,it will fail with the above error.
With the fixed package, it will display the help menu.
As a more complete test:
excute on a terminal: locust -f /usr/share/doc/python3-locust/examples/fast_http_locust.py
Open browser, and go to http://127.0.0.1:8089
It will display the locust interface.
On the interface, click on "NEW" and then "START SWARM" in the new window.
let it run for few minutes and then click "STOP".
then click on "CHARTS" tab to see the graph, and "LOGS" tab to see the log
[ Where problems could occur ]
The code is not changed, it just adds a runtime dependency on python3-charset-normalizer so that locust can run. And, so there should not be any regression to locust due to this change.
[ Other Info ]
1. This was caused by https://bugs.launchpad.net/bugs/1975541 when "requests" was promoted to main.
2. Debian is not affected by this problem as python3-requests in Debian still depends on python3-charset-normalizer and so as a result "locust" works in Debian.
3. The oracular fix also adds python3-charset-normalizer to build-dependency to fix the tests. In the previous build log at https://launchpadlibrarian.net/721479475/buildlog_ubuntu-noble-amd64.locust_2.24.0-1_BUILDING.txt.gz, it can be seen that all the tests fail because it could not find "charset_normalizer".
In this SRU "python3-charset-normalizer" is only added as a runtime dependency so that the build environment remains unchanged.
