Unreleased

1.9.3

  • Only disable the compile cache for source files impacted by Ruby 3.0.3 [Bug 18250]. This should keep the performance loss to a minimum.

1.9.2

  • Disable compile cache if Ruby 3.0.3's ISeq cache bug is detected. AKA iseq.rb:13 to_binary: wrong argument type false (expected Symbol)
  • Fix Kernel.load behavior: before load 'a' would load a.rb (and other tried extensions) and wouldn't load a unless development_mode: true, now only a would be loaded and files with extensions wouldn't be.

1.9.1

  • Removed a forgotten debug statement in JSON precompilation.

1.9.0

  • Added a compilation cache for JSON.load_file. (#370)

1.8.1

  • Fixed support for older Psych. (#369)

1.8.0

  • Improve support for Pysch 4. (#368)

1.7.7

  • Fix require_relative in evaled code on latest ruby 3.1.0-dev. (#366)

1.7.6

  • Fix reliance on set to be required.
  • Fix Encoding::UndefinedConversionError error for Rails applications when precompiling cache. (#364)

1.7.5

  • Handle a regression of Ruby 2.7.3 causing Bootsnap to call the deprecated untaint method. (#360)
  • Gracefully handle read-only file system as well as other errors preventing to persist the load path cache. (#358)

1.7.4

  • Stop raising errors when encoutering various file system errors. The cache is now best effort, if somehow it can't be saved, bootsnapp will gracefully fallback to the original operation (e.g. Kernel.require). (#353, #177, #262)

1.7.3

  • Disable YAML precompilation when encountering YAML tags. (#351)

1.7.2

  • Fix compatibility with msgpack < 1. (#349)

1.7.1

  • Warn Ruby 2.5 users if they turn ISeq caching on. (#327, #244)
  • Disable ISeq caching for the whole 2.5.x series again.
  • Better handle hashing of Ruby strings. (#318)

1.7.0

  • Fix detection of YAML files in gems.
  • Adds an instrumentation API to monitor cache misses.
  • Allow to control the behavior of require 'bootsnap/setup' using environment variables.
  • Deprecate the disable_trace option.
  • Deprecate the ActiveSupport::Dependencies (AKA Classic autoloader) integration. (#344)

1.6.0

  • Fix a Ruby 2.7/3.0 issue with YAML.load_file keyword arguments. (#342)
  • bootsnap precompile CLI use multiple processes to complete faster. (#341)
  • bootsnap precompile CLI also precompile YAML files. (#340)
  • Changed the load path cache directory from $BOOTSNAP_CACHE_DIR/bootsnap-load-path-cache to $BOOTSNAP_CACHE_DIR/bootsnap/load-path-cache for ease of use. (#334)
  • Changed the compile cache directory from $BOOTSNAP_CACHE_DIR/bootsnap-compile-cache to $BOOTSNAP_CACHE_DIR/bootsnap/compile-cache for ease of use. (#334)

1.5.1

  • Workaround a Ruby bug in InstructionSequence.compile_file. (#332)

1.5.0

  • Add a command line to statically precompile the ISeq cache. (#326)

1.4.9

1.4.8

1.4.7

  • Various performance enhancements
  • Fix race condition in heavy concurrent load scenarios that would cause bootsnap to raise

1.4.6

  • Fix bug that was erroneously considering that files containing . in the names were being required if a different file with the same name was already being required

    Example:

    require 'foo'
require 'foo.en'

    Before bootsnap was considering foo.en to be the same file as foo

  • Use glibc as part of the ruby_platform cache key

1.4.5

  • MRI 2.7 support
  • Fixed concurrency bugs

1.4.4

  • Disable ISeq cache in bootsnap/setup by default in Ruby 2.5

1.4.3

  • Fix some cache permissions and umask issues after switch to mkstemp

1.4.2

  • Fix bug when removing features loaded by relative path from $LOADED_FEATURES
  • Fix bug with propagation of NameError up from nested calls to require

1.4.1

  • Don't register change observers to frozen objects.

1.4.0

  • When running in development mode, always fall back to a full path scan on LoadError, making bootsnap more able to detect newly-created files. (#230)
  • Respect $LOADED_FEATURES.delete in order to support code reloading, for integration with Zeitwerk. (#230)
  • Minor performance improvement: flow-control exceptions no longer generate backtraces.
  • Better support for requiring from environments where some features are not supported (especially JRuby). (#226)k
  • More robust handling of OS errors when creating files. (#225)

1.3.2

  • Fix Spring + Bootsnap incompatibility when there are files with similar names.
  • Fix YAML.load_file monkey patch to keep accepting File objects as arguments.
  • Fix the API for ActiveSupport::Dependencies#autoloadable_module?.
  • Some performance improvements.

1.3.1

  • Change load path scanning to more correctly follow symlinks.

1.3.0

  • Handle cases where load path entries are symlinked (#136)

1.2.1

  • Fix method visibility of Kernel#require.

1.2.0

  • Add LoadedFeaturesIndex to preserve fix a common bug related to LOAD_PATH modifications after loading bootsnap.

1.1.8

  • Don't cache YAML documents with !ruby/object
  • Fix cache write mode on Windows

1.1.7

  • Add bootsnap/setup
  • Support jruby (without compile caching features)
  • Better deoptimization when Coverage is enabled
  • Consider Bundler.bundle_path to be stable

1.0.0

  • (none)

0.3.2

  • Minor performance savings around checking validity of cache in the presence of relative paths.
  • When coverage is enabled, skips optimization instead of exploding.

0.3.1

  • Don't whitelist paths under RbConfig::CONFIG['prefix'] as stable; instead use ['libdir'] (#41).
  • Catch EOFError when reading load-path-cache and regenerate cache.
  • Support relative paths in load-path-cache.
