Write barrier protected objects are allowed to be promoted to the old generation, which means they only get marked on major GC.
The downside is that the `RB_BJ_WRITE` macro MUST be used to set references, otherwise the referenced object may be garbaged collected.
But the `*Descriptor` classes and `Arena` have very few references and are only set in a few places, so it's relatively easy to implement.

PiperOrigin-RevId: 511875342
* Add ruby-specific upb_alloc using xrealloc/xfree for use in Arena_alloc so Ruby GC is aware of allocated memory.
* Add RB_GC_GUARD to DescriptorPool_add_serialized_file to ensure ruby does not aggressively garbage collect arena_rb due to lack of references.
* Ruby: Add support for proto3 json_name in compiler and field definitions
* Address review feedback
* Add test for json_name functionality

Ruby <2.7 does not allow non-finalizable objects to be WeakMap
keys: https://bugs.ruby-lang.org/issues/16035
We work around this by using a secondary map for Ruby <2.7 which
maps the non-finalizable integer to a distinct object.
For now we accept that the entries in the secondary map wil never
be collected. If this becomes a problem we can perform a GC pass
every so often that looks at the contents of the object cache to
decide what can be deleted from the secondary map.

Fixes include:
- Changed Ruby compiler to no longer reject proto2 maps.
- Changed Ruby compiler to emit a warning when proto2 extensions are
present instead of rejecting the .proto file completely.
- Fixed conformance tests to allow proto2 and look up message by name
instead of hardcoding a specific list of messages.
- Fixed conformance test to support the "ignore unknown" option for
JSON.
- Fixed conformance test to properly report serialization errors.
* Removed debug printf and fixed #inspect for floats.
* Fixed compatibility test to have proper semantics for #to_json.
* Updated Makefile.am with new file list.
* Don't try to copy wyhash when inside Docker.
* Fixed bug where we would forget that a sub-object is frozen in Ruby >=2.7.
* Avoid exporting unneeded symbols and refactored a bit of code.
* Some more refactoring.
* Simplified and added more comments.
* Some more comments and simplification. Added a missing license block.

* WIP.
* WIP.
* Builds and runs. Tests need to be updated to test presence.
* Ruby: proto3 presence is passing all tests.
* Fixed a bug where empty messages has the wrong oneof count.
`OneOfDescriptor_each` is registered as a Ruby method which takes zero
parameters, which means it should take one argument.
When Ruby invokes `OneOfDescriptor_each`, it calls it with one parameter
only, which is one less than what `OneOfDescriptor_each` takes before
this commit. Calling a function with the wrong number of argument is
technically undefined behavior.

* Rolled forward again with "Updated upb from defcleanup branch..."
Revert "Revert "Updated upb from defcleanup branch and modified Ruby to use it (#5539)" (#5848)"
This reverts commit 1568deab40.
* A few more merge fixes.
* Updated for defcleanup2 branch.
* Fixed upb to define upb_decode().
* Fixed names of nested messages.
* Revert submodule.
* Set -std=gnu90 and fixed warnings/errors.
Some of our Kokoro tests seem to run with this level of warnings,
and the source strives to be gnu90 compatible. Enforcing it for
every build removes the possibility of some errors showing up in
Kokoro/Travis tests only.
* Fixed remaining warnings with gnu90 mode.
I tried to match warning flags with what Ruby appears to do
in our Kokoro tests.
* Initialize values registered by rb_gc_register_address().
* Fixed subtle GC bug.
We need to initialize this marked value before creating the instance.
* Truly fix the GC bug.
* Updated upb for mktime() fix.
* Removed XOPEN_SOURCE as we are not using strptime().
* Removed fixed tests from the conformance failure list for Ruby.
* Fixed memory error related to oneof def names.
* Picked up new upb changes re: JSON printing.
* Uncomment concurrent decoding test.
This change only adds basic proto2 support without advanced features
like extensions, custom options, maps, etc.
The protoc binary now generates ruby code for proto2 syntax.
However, for now, it is restricted to proto2 files without advanced features
like extensions, in which case it still errors out.
This change also modifies the DSL to add proto messages to the DescriptorPool.
There is a new DSL Builder#add_file to create a new FileDescriptor. With this,
the generated ruby DSL looks something like:
Google::Protobuf::DescriptorPool.generated_pool.build do
add_file "test.proto" do
add_message "foo" do
optional :val, :int32, 1
end
end
end
* This allows for ruby code to catch and handle Protobuf
TypeErrors separately from the standard Ruby TypeError
* Maintains backwards compatibility by having the new
Google::Protobuf::TypeError inherit from the base
TypeError. Any code that was catching TypeError should
continue to work.
* Fix ruby segment fault
1) rb_ary_new cannot be called during allocate function. During allocate
fucntion, the containing object hasn't been marked and rb_ary_new may
invoke gc to collect containing object.
2) The global map should be marked before allocating it. Otherwise it
may be garbage collected.
* Add test
* Remove commented code
* Fix grammer error
* Down-integrate internal changes to github.
* Update conformance test failure list.
* Explicitly import used class in nano test to avoid random test fail.
* Update _GNUC_VER to use the correct implementation of atomic operation
on Mac.
* maps_test.js: check whether Symbol is defined before using it (#2524)
Symbol is not yet available on older versions of Node.js and so this
test fails with them. This change just directly checks whether Symbol is
available before we try to use it.
* Added well_known_types_embed.cc to CLEANFILES so that it gets cleaned up
* Updated Makefile.am to fix out-of-tree builds
* Added Bazel genrule for generating well_known_types_embed.cc
In pull request #2517 I made this change for the CMake and autotools
builds but forgot to do it for the Bazel build.
* Update _GNUC_VER to use the correct implementation of atomic operation on Mac.
* Add new js file in extra dist.
* Bump version number to 3.2.0
* Fixed issue with autoloading - Invalid paths (#2538)
* PHP fix int64 decoding (#2516)
* fix int64 decoding
* fix int64 decoding + tests
* Fix int64 decoding on 32-bit machines.
* Fix warning in compiler/js/embed.cc
embed.cc: In function ‘std::string CEscape(const string&)’:
embed.cc:51:32: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
for (int i = 0; i < str.size(); ++i) {
^
* Fix include in auto-generated well_known_types_embed.cc
Restore include style fix (e3da722) that has been trampled by
auto-generation of well_known_types_embed.cc
* Fixed cross compilations with the Autotools build
Pull request #2517 caused cross compilations to start failing, because
the js_embed binary was being built to run on the target platform
instead of on the build machine. This change updates the Autotools build
to use the AX_PROG_CXX_FOR_BUILD macro to find a suitable compiler for
the build machine and always use that when building js_embed.
* Minor fix for autocreated object repeated fields and maps.
- If setting/clearing a repeated field/map that was objects, check the class
before checking the autocreator.
- Just to be paranoid, don’t mutate within copy/mutableCopy for the autocreated
classes to ensure there is less chance of issues if someone does something
really crazy threading wise.
- Some more tests for the internal AutocreatedArray/AutocreatedDictionary
classes to ensure things are working as expected.
- Add Xcode 8.2 to the full_mac_build.sh supported list.
* Fix generation of extending nested messages in JavaScript (#2439)
* Fix generation of extending nested messages in JavaScript
* Added missing test8.proto to build
* Fix generated code when there is no namespace but there is enum definition.
* Decoding unknown field should succeed.
* Add embed.cc in src/Makefile.am to fix dist check.
* Fixed "make distcheck" for the Autotools build
To make the test pass I needed to fix out-of-tree builds and update
EXTRA_DIST and CLEANFILES.
* Remove redundent embed.cc from src/Makefile.am
* Update version number to 3.2.0-rc.1 (#2578)
* Change protoc-artifacts version to 3.2.0-rc.1
* Update version number to 3.2.0rc2
* Update change logs for 3.2.0 release.
* Update php README
* Update upb, fixes some bugs (including a hash table problem). (#2611)
* Update upb, fixes some bugs (including a hash table problem).
* Ruby: added a test for the previous hash table corruption.
Verified that this triggers the bug in the currently released
version.
* Ruby: bugfix for SEGV.
* Ruby: removed old code for dup'ing defs.
* Reverting deployment target to 7.0 (#2618)
The Protobuf library doesn’t require the 7.1 deployment target so
reverting it back to 7.0
* Fix typo that breaks builds on big-endian (#2632)
* Bump version number to 3.2.0
For JSON encoding we provide a new option to decide at
encode time whether to use camelCase or original proto field
names:
json = MapMessage.encode_json(m, :preserve_proto_fieldnames => true)
This involved fixing a few important bugs in the
Ruby implementation -- mostly cases of mixing
upb field types and descriptor types (upb field
types do not distinguish between int/sint/fixed/sfixed
like descriptor types do).
Also added protobuf-specific exceptions so parse
errors can be caught specifically.

While we are C99 in general, the Ruby build system
for building C extensions enables several flags that
throw warnings for C89/C90 variable ordering rules.
To avoid spewing a million warnings (or trying to
specifically override these warnings with command-line
flags, which would be tricky and possibly fragile)
we conform to Ruby's world of C89/C90.

This adds the Map container and support for parsing and serializing maps
in the protobuf wire format (as defined by the C++ implementation, with
MapEntry submessages in a repeated field). JSON map
serialization/parsing are not yet supported as these will require some
changes to upb as well.
system. The Ruby module build now uses an amalgamated distribution of
upb, and successfully builds a Ruby gem called 'google-protobuf' with
module 'google/protobuf'.
This adds a Ruby extension in ruby/ that is based on the 'upb' library
(now included as a submodule), and adds support for Ruby code generation
to the protoc compiler.
