Changelog

0.6.0 (2016-11-12)

This release has a breaking change. The VPC NAT gateways has been renamed to NAT Gateways per AZ and its get_current_usage() method will now return a list with multiple items. See the changelog entry for #214 below.

This release requires the following new IAM permissions to function:

  • firehose:ListDeliveryStreams
  • #217 - add support for new/missing EC2 instance types: m4.16xlarge, x1.16xlarge, x1.32xlarge, p2.xlarge, p2.8xlarge, p2.16xlarge.
  • #215 - support "Regional Benefit" Reserved Instances that have no specific AZ set on them. Per AWS, these are exempt from On-Demand Running Instances limits like all other RIs.
  • #214 - The VPC "NAT gateways" limit incorrectly calculated usage for the entire region, while the limit is actually per-AZ. It also had strange capitalization that confused users. The name has been changed to "NAT Gateways per AZ" and the usage is now correctly calculated per-AZ instead of region-wide.
  • #221 / PR #222 - Fix bug in handling of STS Credentials where they are cached permanently in connectable.Connectable.credentials, and new AwsLimitChecker instances in the same Python process reuse the first set of STS credentials. This is fixed by storing the Account ID as part of connectable.ConnectableCredentials and getting new STS creds if the cached account ID does not match the current account_id on the Connectable object.
  • PR #216 - add new "Firehose" service with support for "Delivery streams per region" limit.
  • #213 / PR #188 - support AWS cross-sdk credential file profiles via -P / --profile, like awscli.

0.5.1 (2016-09-25)

This release requires the following new IAM permissions to function:

  • ec2:DescribeSpot* or more specifically:
    • ec2:DescribeSpotDatafeedSubscription
    • ec2:DescribeSpotFleetInstances
    • ec2:DescribeSpotFleetRequestHistory
    • ec2:DescribeSpotFleetRequests
    • ec2:DescribeSpotInstanceRequests
    • ec2:DescribeSpotPriceHistory
  • ec2:DescribeNatGateways
  • #51 / PR #201 - Add experimental support for Spot Instance and Spot Fleet limits (only the ones explicitly documented by AWS). This is currently experimental, as the documentation is not terribly clear or detailed, and the author doesn't have access to any accounts that make use of spot instances. This will be kept experimental until multiple users validate it. For more information, see the EC2 limit documentation.
  • PR #204 contributed by hltbra to add support for VPC NAT Gateways limit.
  • Add README and Docs link to waffle.io board.
  • Fix bug where --skip-ta command line flag was ignored in :py:meth:`~.Runner.show_usage` (when running with -u / --show-usage action).
  • Add link to waffle.io Kanban board
  • #202 - Adds management of integration test IAM policy via Terraform.
  • #211 - Add working download stats to README and docs
  • Fix broken landscape.io badges in README and docs
  • #194 - On Limits page of docs, clarify that Running On-Demand Instances does not include Reserved Instances.
  • Multiple tox.ini changes:
    • simplify integration and unit/versioncheck testenv blocks using factors and reuse
    • py26 testenv was completely unused, and py26-unit was running and working with mock==2.0.0
    • use pytest<3.0.0 in py32 envs
  • #208 - fix KeyError when timestamp key is missing from TrustedAdvisor check result dict

0.5.0 (2016-07-06)

This release includes a change to awslimitchecker's Python API. awslimitchecker.limit.AwsLimit.get_limit <https://awslimitchecker.readthedocs.io/en/latest/awslimitchecker.limit.html#awslimitchecker.limit.AwsLimit.get_limit> can now return either an int or None, as TrustedAdvisor now lists some service limits as being explicitly "unlimited".

  • #195 - Handle TrustedAdvisor explicitly reporting some limits as "unlimited". This introduces the concept of unlimited limits, where the effective limit is None.

0.4.4 (2016-06-27)

  • PR #190 / #189 - Add support for EBS st1 and sc1 volume types (adds "EBS/Throughput Optimized (HDD) volume storage (GiB)" and "EBS/Cold (HDD) volume storage (GiB)" limits).

0.4.3 (2016-05-08)

0.4.2 (2016-04-27)

This release requires the following new IAM permissions to function:

  • elasticbeanstalk:DescribeApplications
  • elasticbeanstalk:DescribeApplicationVersions
  • elasticbeanstalk:DescribeEnvironments
  • #70 Add support for ElasicBeanstalk service.
  • #177 Integration tests weren't being properly skipped for PRs.
  • #175 the simplest and most clear contributor license agreement I could come up with.
  • #172 add an integration test running against sa-east-1, which has fewer services than the popular US regions.

0.4.1 (2016-03-15)

  • #170 Critical bug fix in implementation of #71 - SES only supports three regions (us-east-1, us-west-2, eu-west-1) and causes an unhandled connection error if used in another region.

0.4.0 (2016-03-14)

This release requires the following new IAM permissions to function:

  • rds:DescribeAccountAttributes
  • iam:GetAccountSummary
  • s3:ListAllMyBuckets
  • ses:GetSendQuota
  • cloudformation:DescribeAccountLimits
  • cloudformation:DescribeStacks

Issues addressed:

  • #150 add CHANGES.rst to Sphinx docs

  • #85 and #154

    • add support for RDS 'DB Clusters' and 'DB Cluster Parameter Groups' limits
    • use API to retrieve RDS limits
    • switch RDS from calculating usage to using the DescribeAccountAttributes usage information, for all limits other than those which are per-resource and need resource IDs (Max auths per security group, Read replicas per master, Subnets per Subnet Group)
    • awslimitchecker now requires an additional IAM permission, rds:DescribeAccountAttributes

  • #157 fix for TrustedAdvisor polling multiple times - have TA set an instance variable flag when it updates services after a poll, and skip further polls and updates if the flag is set. Also add an integration test to confirm this.

  • #50 Add support for IAM service with a subset of its limits (Groups, Instance Profiles, Policies, Policy Versions In Use, Roles, Server Certificates, Users), using both limits and usage information from the GetAccountSummary API action. This requires an additional IAM permission, iam:GetAccountSummary.

  • #48 Add support for S3 Buckets limit. This requires an additional IAM permission, s3:ListAllMyBuckets.

  • #71 Add support for SES service (daily sending limit). This requires an additional IAM permission, ses:GetSendQuota.

  • #69 Add support for CloudFormation service Stacks limit. This requires additional IAM permissions, cloudformation:DescribeAccountLimits and cloudformation:DescribeStacks.

  • #166 Speed up TravisCI tests by dropping testing for PyPy and PyPy3, and only running the -versioncheck tests for two python interpreters instead of 8.

0.3.2 (2016-03-11)

  • #155 Bug fix for uncaught KeyError on accounts with Trusted Advisor (business-level support and above). This was caused by an undocumented change released by AWS between Thu, 10 Mar 2016 07:00:00 GMT and Fri, 11 Mar 2016 07:00:00 GMT, where five new IAM-related checks were introduced that lack the region data field (which the TrustedAdvisorResourceDetail API docs still list as a required field).

0.3.1 (2016-03-04)

  • #117 fix Python 3.5 TravisCI tests and re-enable automatic testing for 3.5.
  • #116 add t2.nano EC2 instance type; fix typo - "m4.8xlarge" should have been "m4.10xlarge"; update default limits for m4.(4|10)xlarge
  • #134 Minor update to project description in docs and setup.py; use only _VERSION (not git) when building in RTD; include short description in docs HTML title; set meta description on docs index.rst.
  • #128 Update Development and Getting Help documentation; add GitHub CONTRIBUTING.md file with link back to docs, as well as Issue and PR templates.
  • #131 Refactor TrustedAdvisor interaction with limits for special naming cases (limits where the TrustedAdvisor service or limit name doesn't match that of the awslimitchecker limit); enable newly-available TrustedAdvisor data for some EC2 on-demand instance usage.

0.3.0 (2016-02-18)

  • Add coverage for one code branch introduced in PR #100 that wasn't covered by tests.
  • #112 fix a bug in the versioncheck integration tests, and a bug uncovered in versioncheck itself, both dealing with checkouts that are on a un-cloned branch.
  • #105 build and upload wheels in addition to sdist
  • #95 major refactor to convert AWS client library from boto to boto3. This also includes significant changes to the internal connection logic and some of the internal (private) API. Pagination has been moved to boto3 wherever possible, and handling of API request throttling has been removed from awslimitchecker, as boto3 handles this itself. This also introduces full, official support for python3.
  • Add separate localdocs tox env for generating documentation and updating output examples.
  • #113 update, expand and clarify documentation around threshold overrides; ignore some sites from docs linkcheck.
  • #114 expanded automatic integration tests
  • Please note that version 0.3.0 of awslimitchecker moved from using boto as its AWS API client to using boto3. This change is mostly transparent, but there is a minor change in how AWS credentials are handled. In boto, if the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables were set, and the region was not set explicitly via awslimitchecker, the AWS region would either be taken from the AWS_DEFAULT_REGION environment variable or would default to us-east-1, regardless of whether a configuration file (~/.aws/credentials or ~/.aws/config) was present. With boto3, it appears that the default region from the configuration file will be used if present, regardless of whether the credentials come from that file or from environment variables.

  • Fix #87 run coverage in all unit test Tox environments, not a dedicated env
  • Fix #75 re-enable py26 Travis builds now that pytest-dev/pytest#1035 is fixed (pytest >= 2.8.3)
  • Fix #13 re-enable Sphinx documentation linkcheck
  • Fix #40 add support for pagination of API responses (to get all results) and handle pagination for all current services
  • Fix #88 add support for API-derived limits. This is a change to the public API for awslimitchecker.limit.AwsLimit and the CLI output.
  • Fix #72 add support for some new limits returned by Trusted Advisor. This renames the following limits: * EC2/EC2-VPC Elastic IPs to EC2/VPC Elastic IP addresses (EIPs) * RDS/Read Replicas per Master to RDS/Read replicas per master * RDS/Parameter Groups to RDS/DB parameter groups
  • Fix #84 pull some EC2 limits from the API's DescribeAccountAttributes action
  • Fix #94 pull AutoScaling limits from the API's DescribeAccountLimits action
  • Add autoscaling:DescribeAccountLimits and ec2:DescribeAccountAttributes to required IAM permissions.
