Curl as failover of wget for connectors

[ltoussaint]

OSX does not have wget installed by default. Allow connectors to use curl as failover.

Don't forget to mention new Gitlab connector in README/CHANGELOG because no feature was dedicated.

Do python version of gitlab connector is working?

[ltoussaint]

This connector only work with PHP. With python it will return an empty string.

[geoffroy-aubry]

OK. Hmm… so why give priority to pyhton language in feature_subject_gitlab.sh, line 49? It wouldn't be better if python version doesn't work to simply remove it and throw an error?

[ltoussaint]

The chosen language always was PHP if installed. So the code with python was never call.

But to be compatible with the most OS, I did the python version. So it should be ok now.

"The chosen language always was PHP if installed.": sorry, but the code below seems say the opposite. Currently, in each connector, the chosen language is PHP if and only if Python is not installed. ^^

But if your Python version is working, it's fine :-)

# Python or PHP ?
language='?'
which python 1>/dev/null 2>&1
if [ $? -eq 0 ]; then
    language='python'
else
    which php 1>/dev/null 2>&1
    if [ $? -eq 0 ]; then
        language='php'
    fi
fi

[ltoussaint]

Yes, this code was added when I did the python version ;-)

OK, thx
