Changelog

Version history

0.9.52

• err2.Stderr helpers for Catch/Handle to direct auto-logging + snippets
• assert package Shorter Longer helpers for automatic messages
• asserter package remove deprecated slow reflection based funcs
• cleanup and refactoring for sample apps

0.9.51

• flag package support to set err2 and assert package configuration
• err2.Catch default mode is to log error
• cleanup and refactoring, new tests and benchmarks

0.9.5 mistake in build number: 5 < 41

• flag package support to set err2 and assert package configuration
• err2.Catch default mode is to log error
• cleanup and refactoring, new tests and benchmarks

0.9.41

• Issue #18: bug fixed: noerr-handler had to be the last one of the err2 handlers

0.9.40

• Significant performance boost for: defer err2.Handle/Catch()
  • 3x faster happy path than the previous version, which is now equal to simplest defer function in the err-returning function . (Please see the defer benchmarks in the err2_test.go and run make bench_reca)
  • the solution caused a change to API, where the core reason is Go's optimization "bug". (We don't have confirmation yet.)
• Changed API for deferred error handling: defer err2.Handle/Catch()
  • Obsolete:

    defer err2.Handle(&err, func() {}) // <- relaying closure to access err val

  • Current version:

    defer err2.Handle(&err, func(err error) error { return err }) // not a closure

    Because handler function is not relaying closures any more, it opens a new opportunity to use and build general helper functions: err2.Noop, etc.
  • Use auto-migration scripts especially for large code-bases. More information can be found in the scripts/ directory's readme file.
  • Added a new (experimental) API:

    defer err2.Handle(&err, func(noerr bool) {
            assert.That(noerr) // noerr is always true!!
            doSomething()
    })

    This is experimental because we aren't sure if this is something we want to have in the err2 package.
• Bug fixes: ResultX.Logf() now works as it should
• More documentation

0.9.29

• New API for immediate error handling: try out handle/catch err val := try.Out1strconv.Atois.Catch(10)
• New err2.Catch API for automatic logging
• Performance boost for assert pkg: defer assert.PushTester(t)()
• Our API has now all the same features Zig's error handling has

0.9.1

• Performance boost for assert pkg: assert.That(boolVal) == if boolVal
• Go version 1.18 is a new minimum (was 1.19, use of atomic.Pointer)
• Generic functions support type aliases
• More support for assert package for tests: support for cross module asserts during the tests
• Using assert pkg for tests allow us to have traversable call stack during unit tests -- cross module boundaries solved
• Implementation: simplified assert pkg to testing pkg integration, and especially performance

0.9.0

• Clean and simple API
• Removing deprecated functions:
  • Only err2.Handle for error returning functions
  • Only err2.Catch for function that doesn't return error
  • Please see scripts/README.md for Auto-migration for your repos
• Default err2.SetPanicTracer(os.Stderr) allows defer err2.Catch()

0.8.14

• err2.Handle supports sentinel errors, can now stop panics
• err2.Catch has one generic API and it stops panics as default
• Deprecated CatchTrace and CatchAll which merged with Catch
• Auto-migration offered (similar to go fix)
• Code snippets added
• New assertion functions
• No direct variables in APIs (race), etc.

0.8.13

• Bug-fix: automatic error strings for methods
• Added API to set preferred error string Formatter or implement own
