Python DLR library prints an import message which breaks the setup script

[edtamarin]

Issue

When running the setup script, dlr v1.10 is installed. This version prints out an information message when the module is imported in the interpreter:

You acknowledge and agree that DLR collects the following metrics to help improve its performance.
By default, Amazon will collect and store the following information from your device:

record_type: <enum, internal record status, such as model_loaded, model_>, arch: <string, platform architecture, eg 64bit>, osname: <string, platform os name, eg. Linux>, uuid: <string, one-way non-identifable hashed mac address, eg. 8fb35b79f7c7aa2f86afbcb231b1ba6e>,
dist: <string, distribution of os, eg. Ubuntu 16.04 xenial>, machine: <string, retuns the machine type, eg. x86_64 or i386>, model: <string, one-way non-identifable hashed model name, eg. 36f613e00f707dbe53a64b1d9625ae7d>

If you wish to opt-out of this data collection feature, please follow the steps below: 1. Disable it with through code: from dlr.counter.phone_home import PhoneHome PhoneHome.disable_feature() 2. Or, create a config file, ccm_config.json inside your DLR target directory path, i.e. python3.6/site-packages/dlr/counter/ccm_config.json. Then added below format content in it, {"enable_phone_home" : false} 3. Restart DLR application. 4. Validate this feature is disabled by verifying this notification is no longer displayed, or programmatically with following command: from dlr.counter.phone_home import PhoneHome PhoneHome.is_enabled() # false as disabled

This message is seen by the install script, which picks it up at the install location of the library and the following error is generated:

This prevents the libdlr.so file from being copied to the appropriate location.

Proposed solution

In the install script, replace

dlr_loc=$(python3  << EOF
import dlr 
print(dlr.__file__)
EOF
)

with

dlr_loc=$(python3 -W ignore -c "import sys,os; sys.stdout = open(os.devnull, 'w'); import dlr; sys.stdout = sys.__stdout__; print(dlr.__file__)")

This solution temporarily blocks printing to stdout while dlr is imported and prevents the import message from being parsed in the install script.
