v9.5.2

New Features

• Custom HTTP responses can be configured using ha_proxy.custom_http_error_files. It takes
  a map of status codes to raw http responses to send. This allows operators to customize things
  like the 502/503 errors returned by HA Proxy.

v9.5.0

New Features

• haproxy now supports a graceful drain on connections (disabled by default).
  To enable it, use ha_proxy.drain_enable: true. If haproxy does not complete
  its drain within the ha_proxy.drain_timeout perioud (defaults to 30s), it will
  shut off haproxy without waiting for in-flight connections to complete.

  ha_proxy.drain_frontend_grace_time can be used to set a delay between shutdown and
  when the frontends stop accepting connections.

v9.4.0

Improvements

• Converted HAProxy to start using BPM
• Updated default manifest to use the xenial stemcell
• The default value for the haproxy keep-alive timeout is now 6 seconds, to improve compatibility with
  various HTTP clients.
• The keepalived job now provides a link including the VIP that keepalived uses
• Added configurable ha_proxy.max_connections and ha_proxy.max_open_files properties for controlling
  the number of simultaneous HAProxy connections without creating new boshreleases now.
• Fixed an issue with the ha_proxy.crt_list property not properly detecting mutual tls settings unless
  the verify key was present on every certificate.

Fixes

• Bumps HAProxy to v1.8.17

v9.3.0

New Features

• Added support for HAProxy's experimental multi-threading logic.
  Previously, this boshrelease used ha_proxy.threads to set the nbproc
  value of HAProxy, causing a multi-threaded behavior by spawning multiple
  HAProxy processes. In v1.8.x, built-in multi-threading was enabled in an
  experimental mode. This can be enabled via ha_proxy.nbthread. Adding multi-
  threading works in-conjunction with multi-process HAProxy, or on its own.
  To reduce confusion, the ha_proxy.threads property has been deprecated,
  but still affects the number of processes run. In the future, ha_proxy.nbproc
  should be used. To enable the experimental multi-threading, use ha_proxy.nbthread.

  Note: One of the upsides to multi-thread vs multi-process is that the threads
  are able to share memory, resulting in the need for only one stats socket/listener.
  One of the downsides is that LUA scripts are globally single-threaded, so only one
  script will run at a time, ever. HAProxy can still service requests that don't involve
  calling LUA code, but multiple calls requiring LUA will be serialized.

Updates

• HAProxy was updated to v1.8.13

Deprecation Warning!

• ha_proxy.threads is hereby deprecated, and will be removed in the next major
  version of the boshrelease. It previously referred to the number of HAProxy
  processes running, and was going to be confusing with the added thread support.
  Please use ha_proxy.nbproc instead.

v9.2.0

KNOWN ISSUES

There is a bug in this release which results in it being incompatible with the CF TCP Router (or anything providing the tcp_router link

New Features

• The haproxy job can now be easily configured to use the CF Routing tier's HTTP-based
  health checks. Specify ha_proxy.backend_use_http_health = true to enable it. If custom
  ports or URIs are necessary for HTTP backend health checks, they can be specified via
  ha_proxy.backend_http_health_port and ha_proxy.backend_http_health_uri. There are similar
  properties available for the ha_proxy.routed_backends datastructures via backend_use_http_health,
  backend_http_health_port, and backend_http_health_uri properties on each routed backend
  definition.

  Generic TCP routing was not updated with support for custom HTTP backends. However, when the
  tcp_router link is consumed from Cloud Foundry, it now enforces the use of HTTP health checks
  to the TCP router. Previously, only a TCP port check on port 80 was done.

• Added a property to allow lua scripts to be easily loaded into the HA proxy config
  via ha_proxy.lua_scripts. This is a list of full paths to the lua script on disk.
  You'll want to provide those with some other boshrelease.

• Added a property for providing arbitrary frontend config to haproxy via ha_proxy.frontend_config.
  This applies to all of the haproxy frontends.

• Added a property for providing arbitrary backend config to haproxy backends via the ha_proxy.backend_config,
  and ha_proxy.tcp_backend_config (the former will be used on default + routed HTTP backends, the latter on
  all tcp-mode backends).

• Added a property for providing arbitrary global config to haproxy via ha_proxy.global_config.

• Improved logging to include info related to health check/backend status, and elevate log levels for error messages.

Fixes

• The default logging endpoint has changed from 127.0.0.1 to /dev/log, which resolves issues where haproxy
  was deployed on a VM that did not have TCP/UDP listeners enabled in rsyslog.

v9.1.0

New Features

• Added a new ha_proxy.raw_config attribute, to allow users to specify an
  entire haproxy config to be used. This replaces all other haproxy config logic
  in the boshrelease, and should be used with care.
• HAProxy is now compiled with LUA support, which may be useful when providing
  a custom config.
