| Complete this Two-Stage (Open-and-Closed) circuit breaker implementation. | |
| Initial state is set to _is_closed = True. | |
| When the number of failure reaches to the limit, set the status to _is_closed = False along with _open_since time. Whenever the current time passes _open_since + _reset_timeout, the circuit breaker will let the call go through. | |
| If the attempt is successful, reset the status to _is_closed = True and reset the failure count to zero. | |
| To test your code, place this cbdemo.py (Links to an external site.) under the same location as cb.py. See the expected output (Links to an external site.) for a correct solution. | |

| # First of all you need to have a clean clone of the source repository so we didn't screw the things up. | |
| git clone git://server.com/my-repo1.git | |
| # After that you need to do some preparations on the source repository, nuking all the entries except the folder you need to move. Use the following command | |
| git filter-branch --subdirectory-filter your_dir -- -- all | |
| # This will nuke all the other entries and their history, creating a clean git repository that contains only data and history from the directory you need. If you need to move several folders, you have to collect them in a single directory using the git mv command. |
Executable fat jars are easy to deploy and upgrade, and don't need wrapper scripts to pull in the classpath. You can use the Gradle fatjar plugin to create executable, self-contained jars in Gradle, akin to the Shade plugin for Maven -
apply plugin: 'fatjar'
buildscript {
dependencies {
classpath 'eu.appsatori:gradle-fatjar-plugin:0.1.3'
}
}

| You must use hashlib to hash the node ('0.0.0.0:3000') and key ('mykey') combination. | |
| Example: | |
| x = '0.0.0.0:3000' + 'my-key' | |
| x = node + key | |
| hash = hashlib.md5(x).hexdigest() | |
