Using ensure_future() not supported on Ubuntu 14.04

[n1koo]

This might be design, but usage of ensure_future() (eg. https://github.com/mbevand/silentarmy/blob/master/silentarmy#L105 ) in silentarmy requires Python 3.4.4+ .

Trusty only has up to 3.4.3 available (http://packages.ubuntu.com/trusty-updates/python3.4)

Maybe deprecate support for 14.04 ?

n1ko@orangeminer:~/silentarmy$ ./silentarmy

Oh what a bummer! I wanted to support 14.04 and did not think my Python would be incompatible. Oh well I documented it in the readme. I certainly want to try to make 14.04 fully supported.

Seems to work in 14.04 after installing python3.5 manually. Seeing #9 but mining is totally fine and getting +40% boost compared to zogminer so this is pretty huge!

[n1koo]

For anyone stumbling upon here looking at the same issue, heres a gist to install deps not available in 14.04 and also edit the silentarmy to use the custom 3.5 rather than 3.4 from system: https://gist.github.com/n1koo/7c0455b674d3c3a9d4cccf53837b270e

@n1koo Thank you for documenting the workaround in so much details! Also I added a pointer to this github issue: 6a038fe

Probably should have looked at the issues list earlier, but just in case it helps anyone before mrb gets a chance to review, I have a pending PR: #27 that should get the miner working in 3.3-3.4.3; I've tested on 3.3.6 in Arch but don't have any Ubuntu 14.04 LTS systems so maybe someone can give it a spin overnight and comment in the PR issue if it doesn't work. You can build/compile from https://github.com/lhl/silentarmy which is an up-to-date fork as of right now except for the asyncio backport code.

[mbevand]

Yes I am going to look into lhl's pull request tomorrow.

I confirm that @lhl's branch works fine. I had to revert the sys.path commit and manually copy sa-solver to lib/asyncio though.

[lhl]

Hmm @PabloCastellano, that's interesting - so you reverted 0863a83?

The reason that I had to swap to sys.path.append() instead of sys.path.insert() is because silentarmy depends on sys.path[0] to assign the sa-solverlocation. By default sys.path[0] is usually ''. Arguably, sa-solver PATH should probably be assigned by setting a HOMEPATH or SOLVERPATH like how I set the LIBPATH with os.path.dirname(os.path.realpath(__file__)), but I was doing my best to design this patch to be the least invasive possible solution.

[mbevand]

This is fixed - SA now requires Python 3.3 or above (instead of 3.5): 62a78cf

So SA works out of the box on Ubuntu 14.04.
