g:plug_timeout is not respected for SSL connection timeout

[yous]

When I do :PlugUpdate, it takes much more time than expected according to the configuration of g:plug_timeout and g:plug_retries.

let g:plug_timeout = 10
let g:plug_retries = 0

It takes over 300 seconds, and it's because of vim-open-color entry, which gets SSL connection timeout.

Updated. Elapsed time: 306.388908 sec.

I think this is the minimal vimrc:

let g:plug_timeout = 10
let g:plug_retries = 0

filetype off

call plug#begin()

Plug 'https://localhost/fake/repo.git'

call plug#end()

Run nc -l 443 to raise SSL timeout, then try :PlugUpdate.

[junegunn]

vim-plug/README.md

Lines 304 to 305 in d863d07

	| `g:plug_timeout` | 60 | Time limit of each task in seconds (*Ruby & Python*) |
	| `g:plug_retries` | 2 | Number of retries in case of timeout (*Ruby & Python*) |

Those variables are only used by the legacy Ruby/Python parallel installers. We don't enforce any timeouts when using the Vim 8+/Neovim installers.

[yous]

I see, then is there a way to abort the ongoing :PlugUpdate, so I can retry unfinished entries with R?

[junegunn]

The ongoing processes will be aborted when you close the plug window, but we don't have a way to retry only the aborted processes afterward. Never felt that I needed it. If I had to abort the update, I can then just re-run :PlugUpdate and it doesn't take long to do the whole thing again, so it doesn't bother me that much. Does this happen to you often?

[yous]

I also didn't have issues for years, but I think something goes weird with my internet connection to GitHub nowadays. I've been experiencing timeouts repeatedly, getting more bothered.

[yous]

Seeing #1093, maybe this is because of rate limiting as I have 60 plugins, and timeout occurs only when I'm on a shared network.
