Crash due to Gotty.(*TermInfo).GetAttribute #184

Closed alexaandru closed 6 years ago

alexaandru commented 6 years ago

Hello,

I just downloaded the latest sam version (0.2.2) created a template.yaml as instructed in the documentation and attempted to start sam local start-api. The result is this for any of {xterm-256color,urxvt,rxvt,xterm,ansi} TERM values (tried different terminals hoping Gotty would be able to handle any, but it wasn't):

$ sam local start-api

alexaandru commented 6 years ago

It worked if I pulled the images manually (docker run lambci/lambda) :)

PaulMaddox commented 6 years ago

Hi,

Can you give a bit more detail around what OS you're running? e.g. cat /etc/lsb-release would help.

alexaandru commented 6 years ago

Hello,

Sure:

$ lsb_release -a
No LSB modules are available.
Distributor ID: LinuxMint
Description:    Linux Mint 17.3 Rosa
Release:    17.3
Codename:   rosa

Initially I tried it from VS Code builtin terminal, then from urxvt, gnome-console and xterm and they all crashed the exact same way. Then I ran:

docker run lambci/lambda
docker run lambci/lambda:python2.7

and it worked. Docker version is 17.09.0-ce. Pulling the images manually worked as expected/no error.

alexaandru commented 6 years ago

This seems related: https://github.com/docker/for-mac/issues/1515 if not the same issue.

sanathkr commented 6 years ago

Not relevant anymore since v0.3.0 is written in Python
