# Donate CPU
|
|
#
|
|
# A script a user can run to donate CPU to cppcheck project
|
|
#
|
|
# Syntax: donate-cpu.py [-jN] [--package=url] [--stop-time=HH:MM] [--work-path=path] [--test] [--bandwidth-limit=limit]
|
|
# -jN Use N threads in compilation/analysis. Default is 1.
|
|
# --package=url Check a specific package and then stop. Can be useful if you want to reproduce
|
|
# some warning/crash/exception/etc..
|
|
# --stop-time=HH:MM Stop analysis when time has passed. Default is that you must terminate the script.
|
|
# --work-path=path Work folder path. Default path is cppcheck-donate-cpu-workfolder in your home folder.
|
|
# --test Connect to a donate-cpu-server that is running locally on port 8001 for testing.
|
|
# --bandwidth-limit=limit Limit download rate for packages. Format for limit is the same that wget uses.
|
|
# Examples: --bandwidth-limit=250k => max. 250 kilobytes per second
|
|
# --bandwidth-limit=2m => max. 2 megabytes per second
|
|
# --max-packages=N Process N packages and then exit. A value of 0 means infinitely.
|
|
# --no-upload Do not upload anything. Defaults to False.
|
|
#
|
|
# What this script does:
|
|
# 1. Check requirements
|
|
# 2. Pull & compile Cppcheck
|
|
# 3. Select a package
|
|
# 4. Download package
|
|
# 5. Analyze source code
|
|
# 6. Upload results
|
|
# 7. Repeat from step 2
|
|
#
|
|
# Quick start: just run this script without any arguments
