2021-05-19Implement YAML.safe_dump to make safe_load more usable.Jean Boussier
In case where Psych is used as a two way serializers, e.g. to serialize some cache or config, it is preferable to have the same restrictions on both load and dump. Otherwise you might dump and persist some objects payloads that you later won't be able to read.

2020-12-23[ruby/psych] Optimize cache with `compare_by_identity`Marc-Andre Lafortune
Using `compare_by_identity` gives a 4x performance boost on cache hits. Benchmark in https://github.com/JuanitoFatas/fast-ruby/issues/189
2020-07-16Remove private_iv_getCharles Oliver Nutter
The only remaining use of this function was to get the internal message object from an exception's hidden `mesg` instance variable to allow it to be dumped wiithout converting to a string. As discussed in #103, this exposes internal implementation details of CRuby, and ultimately does not provide any real utility to the user since they can't directly inspect this hidden variable. The test change here is to reflect CRuby behavior that denies equality if the internal message objects do not match, as is the case after the exception has been loaded and now has a simple String value. The impact to users is that exceptions with special hidden message objects will convert those objects to String during marshaling through YAML. I believe this only affects NameError and its descendants, since users can't set this field directly on their own exception types. Fixes #103.

When the Hash is revived, the ivars will be set before elements. This is for the case when the hash setter depends on ivars set on the hash.

Fixes #216. Fixes part of #217.
2015-01-13Fix block chomping and add more testsJakub Jirutka
When no [chomping indicator][1] is specified for a folded or literal block, then YAML parser should preserve the final line break (i.e. the string should end with \n). This implies that when dumping a string *without* the trailing newline to YAML, we should specify the stripping indicator (-). [1]: http://yaml.org/spec/1.2/2009-07-21/spec.html#id2593651
2015-01-12Preset @line_width in YAMLTree#initialize for better performanceJakub Jirutka
2015-01-12Use appropriate style for serialized stringsJakub Jirutka
When psych parses YAML with string in the folded style as: a: > some inline content and serializes it back to YAML, then it renders the string in the literal style instead: a: | some inline content This patch fixes this behaviour. When a string doesn't contain newlines (blank line at the end is ignored) and it's not necessary to be quoted, then it will use plain style or folded style according to its length and the `line_width` option. # line_width = 100 a: some inline content # line_width = 11 a: > some inline content This change was originally proposed by @Iazel.

Additionally, it is assumed that these objects will have implemented `respond_to?` and `class`, (e.g. SimpleDelegator). These assumptions are reasonably inline with the assumptions of `Marshal` in regards to `BasicObject`s.
