Running P4Python versions side-by-side on Windows
In the Perforce supported version of P4Python, the main module was renamed
from "p4" to "P4". Since Python is case-sensitive, it's possible to have
both modules loaded; however, on Windows it's not possible to have the files
"p4.py" and "P4.py" in the same folder. If you run the installers, one
version will overwrite the other. However, you can manually install the
public depot version of P4Python, and run it side-by-side with the Perforce
version. Here are the steps to get this to work:
1. Install the Perforce version of P4Python
2. Create a new folder for the public depot version of P4Python. I
created my folder here:
3. Copy the following files into the new folder.
You can get these files off a machine that has the public depot version
of P4Python installed (will be in the site-packages folder), or you can
compile P4Client.pyd from source.
4. Set the environment variable PYTHONPATH to the new folder (or append
it to the list if PYTHONPATH is already defined).
You can test with the following short script:
import p4 as pubdepotAPI
import P4 as perforceAPI
p4 = pubdepotAPI.P4()
info1 = p4.run_info()
p4 = perforceAPI.P4()
info2 = p4.run_info()
if info1['serverAddress'] == info2['serverAddress']:
print "Both versions loaded and return same results!"
