# HEAD

## 3.4.1

- Fix: Use `Process.clock_gettime(CLOCK_MONOTONIC)` for elapsed time tracking so retry timing is immune to wall-clock adjustments (NTP, manual changes).
- Fix: Handle `max_elapsed_time: nil` gracefully instead of raising `NoMethodError`.
- Remove dead `* 1.0` float coercion in `ExponentialBackoff#randomize`.

## 3.4.0

- Add `retry_if` option to support custom retry predicates, including checks against wrapped `exception.cause` values.

## 3.3.0

- Refactor `Retriable.retriable` internals into focused private helpers to improve readability while preserving behavior.
- Modernize `.rubocop.yml` with explicit modern defaults to enable new cops while preserving existing project style policies.

## 3.2.1

- Remove executables from gemspec as it was polluting the path for some users. Thanks @hsbt.

## 3.2.0

- Require ruby 2.3+.
- Fix: Ensure `tries` value is overridden by `intervals` parameter if both are provided and add a test for this. This is always what the README stated but the code didn't actually do it.
- Fix: Some rubocop offenses.

## 3.1.2

- Replace `minitest` gem with `rspec`
- Fancier README
- Remove unnecessary short circuit in `randomize` method

## 3.1.1

- Fix typo in contexts exception message.
- Fix updating the version in the library.

## 3.1.0

- Added [contexts feature](https://github.com/kamui/retriable#contexts). Thanks to @apurvis.

## 3.0.2

- Add configuration and options validation.

## 3.0.1

- Add `rubocop` linter to enforce coding styles for this library. Also, fix rule violations.
- Removed `attr_reader :config` that caused a warning. @bruno-
- Clean up Rakefile testing cruft. @bruno-
- Use `.any?` in the `:on` hash processing. @apurvis

## 3.0.0

- Require ruby 2.0+.
- Breaking Change: `on` with a `Hash` value now matches subclassed exceptions. Thanks @apurvis!
- Remove `awesome_print` from development environment.

## 2.1.0

- Fix bug #17 due to confusing the initial try as a retry.
- Switch to `Minitest` 5.6 expect syntax.

## 2.0.2

- Change required_ruby_version in gemspec to >= 1.9.3.

## 2.0.1

- Add support for ruby 1.9.3.

## 2.0.0

- Require ruby 2.0+.
- Time intervals default to randomized exponential backoff instead of fixed time intervals. The delay between retries grows with every attempt and there's a randomization factor added to each attempt.
- `base_interval`, `max_interval`, `rand_factor`, and `multiplier` are new arguments that are used to generate randomized exponential back off time intervals.
- `interval` argument removed.
- Accept `intervals` array argument to provide your own custom intervals.
- Allow configurable defaults via `Retriable#configure` block.
- Add ability for `:on` argument to accept a `Hash` where the keys are exception types and the values are a single or array of `Regexp` pattern(s) to match against exception messages for retrial.
- Raise, not return, on max elapsed time.
- Check for elapsed time after next interval is calculated and it goes over the max elapsed time.
- Support early termination via `max_elapsed_time` argument.

## 2.0.0.beta5

- Change `:max_tries` back to `:tries`.

## 2.0.0.beta4

- Change #retry back to #retriable. Didn't like the idea of defining a method that is also a reserved word.
- Add ability for `:on` argument to accept a `Hash` where the keys are exception types and the values are a single or array of `Regexp` pattern(s) to match against exception messages for retrial.

## 2.0.0.beta3

- Accept `intervals` array argument to provide your own custom intervals.
- Refactor the exponential backoff code into it's own class.
- Add specs for exponential backoff, randomization, and config.

## 2.0.0.beta2

- Raise, not return, on max elapsed time.
- Check for elapsed time after next interval is calculated and it goes over the max elapsed time.
- Add specs for `max_elapsed_time` and `max_interval`.

## 2.0.0.beta1

- Require ruby 2.0+.
- Default to random exponential backoff, removes the `interval` option. Exponential backoff is configurable via arguments.
- Allow configurable defaults via `Retriable#configure` block.
- Change `Retriable.retriable` to `Retriable.retry`.
- Support early termination via `max_elapsed_time` argument.

## 1.4.1

- Fixes non kernel mode bug. Remove DSL class, move `#retriable` into Retriable module. Thanks @mkrogemann.

## 1.4.0

- By default, retriable doesn't monkey patch `Kernel`. If you want this functionality,
  you can `require 'retriable/core_ext/kernel'.
- Upgrade minitest to 5.x.
- Refactor the DSL into it's own class.

## 1.3.3.1

- Allow sleep parameter to be a proc/lambda to allow for exponential backoff.

## 1.3.3

- sleep after executing the retry block, so there's no wait on the first call (molfar)

## 1.3.2

- Clean up option defaults.
- By default, rescue StandardError and Timeout::Error instead of [Exception](http://www.mikeperham.com/2012/03/03/the-perils-of-rescue-exception).

## 1.3.1

- Add `rake` dependency for travis-ci.
- Update gemspec summary and description.

## 1.3.0

- Rewrote a lot of the code with inspiration from [attempt](https://rubygems.org/gems/attempt).
- Add timeout option to the code block.
- Include in Kernel by default, but allow require 'retriable/no_kernel' to load a non kernel version.
- Renamed `:times` option to `:tries`.
- Renamed `:sleep` option to `:interval`.
- Renamed `:then` option to `:on_retry`.
- Removed other callbacks, you can wrap retriable in a begin/rescue/else/ensure block if you need that functionality. It avoids the need to define multiple Procs and makes the code more readable.
- Rewrote most of the README

## 1.2.0

- Forked the retryable-rb repo.
- Extend the Kernel module with the retriable method so you can use it anywhere without having to include it in every class.
- Update gemspec, Gemfile, and Raketask.
- Remove echoe dependency.
