It looks like it fails to fetch 'egator' from Bitbucket. Please check if you can clone it with ' git clone https://bitbucket.org/mkharch/egator.git'. I have just checked - it is still there. --M

hi Maxim,
thanks for your answer.
I've changed my rebar.config now to the following :

`{deps,[
{cowboy,".",
{git,"git://github.com/extend/cowboy.git","master"}},
{erlydtl,".",
{git,"git://github.com/evanmiller/erlydtl.git","master"}},
{egator,".*", {git, "https://bitbucket.org/mkharch/egator.git","master"}}
]}.

%%EOF`

Activated is OTP 17 and source revision f6a36a7634e0d08a6ab48d7bdaa5d2b548d96bccand
Now i receive the following compile error:

Which OTP version should i use to successfully compile the last commit in master branch?

[maximk]

I can only guess that it would be the current Erlang version from 7 years ago.

i see, i see.
Ok can you give me some support on how zergling, spawnpool and nginx are connected with each other?
I am on my way to integrate erlang on xen and need some help, your help.
I just missing some schema or diagram.

[maximk]

I remember little of how it works. Here is what I remember: 1. gator application must be running (https://bitbucket.org/mkharch/gator). It is libxl-based and does mostly what standard xl does but faster. 2. There is an Erlang client for gator called egator ( https://bitbucket.org/mkharch/egator). 3. spawnpool (https://github.com/maximk/spawnpool) is zerling-specific. It takes a request from the browser, starts the instance using egator, waits until the instance is ready, and redirects the request to the IP address of the instance. 4. Waiting until the instance is ready is central - there is no polling - somehow it detects the precise moment of readiness. 5. There is some kind of trick to make this redirection possible based on X-Accel-Redirect header, which is taken into account by nginx. I hope it helps. Regards, M

Thank you very much Max!
Why did you decide to drop it off or don't lead it further?
I mean i think it has potential.

cheers, hristo
