Purging the Partials Cache

Partials generation uses an S3 bucket as a cache, to avoid computing the binary diffs of the same file once for each locale. However, if bad partials are generated this cache can end up with invalid entries. Here is how to remove the entire cache:

taskcluster signin

And follow the usual environment variable process.

Set up the AWS temporary credentials, good for about an hour:

AUTH=$(taskcluster api auth awsS3Credentials read-write tc-gp-private-1d-us-east-1 releng/mbsdiff-cache/)
AWS_ACCESS_KEY_ID=$(echo "${AUTH}" | jq -r '.credentials.accessKeyId')
AWS_SECRET_ACCESS_KEY=$(echo "${AUTH}" | jq -r '.credentials.secretAccessKey')
AWS_SESSION_TOKEN=$(echo "${AUTH}" | jq -r '.credentials.sessionToken')
export AWS_ACCESS_KEY_ID
export AWS_SECRET_ACCESS_KEY
export AWS_SESSION_TOKEN
AUTH=

aws cli commands should now authenticate.

aws s3 ls s3://tc-gp-private-1d-us-east-1/releng/mbsdiff-cache/ --recursive

Remove the files:

aws s3 rm s3://tc-gp-private-1d-us-east-1/releng/mbsdiff-cache/ --recursive
