We have some special code in wrap_memcpy.c to ensure that we use the
2.2.5 version of memcpy, for compatibility with older versions of glibc.
However, we need to make sure we only attempt to do this when we are
actually building with glibc, so that the code can also build
successfully against other libc implementations such as musl.
This commit adds a __wrap_memcpy function and a linker flag to use that
in place of memcpy for our Ruby gem C extension. This allows us to
always use the 2.2.5 version of memcpy, making it possible to use the
gem on distributions with pre-2.14 versions of glibc.
Before this change:
$ objdump -T protobuf_c.so | grep memcpy
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.3.4 __memcpy_chk
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.14 memcpy
After:
$ objdump -T protobuf_c.so | grep memcpy
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.2.5 memcpy
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.3.4 __memcpy_chk
0000000000042450 g DF .text 0000000000000005 Base __wrap_memcpy
This is based on gRPC's solution to a similar problem:

This fixes issue #2783.
* 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
self->field_type_class returns the correct Ruby class, get_def_obj
returns the Descriptor object used to generate the Ruby class via
msgclass, so to compare the two types we get the msgclass from the
descriptor.
* Factored Conformance test messages into shared test schema.
* Updated benchmarks to use new proto3 message locations.
* Fixed include path.
* Conformance: fixed include of Python test messages.
* Make maven in Rakefile use --batch-mode.
* Revert changes to benchmarks.
On second thought I think a separate schema for
CPU benchmarking makes sense.
* Try regenerating C# protos for new test protos.
* Removed benchmark messages from test proto.
* Added Jon Skeet's fixes for C#.
* Removed duplicate/old test messages C# file.
* C# fixes for test schema move.
* Fixed C# to use the correct TestAllTypes message.
* Fixes for Objective C test schema move.
* Added missing EXTRA_DIST file.
This makes a couple of changes to fix the tests for JRuby 1.7:
- Avoid using assert_false since that assertion seems not to exist in
older versions
- Disable a test related to respond_to? for JRuby. It's hard to tell
what is going wrong here but it looks like probably a JRuby bug that
has been fixed in more recent versions.
Uses values from the removed `Gemfile.lock` as a baseline for version requirements, though it has been observed to work with the latest versions of all the referenced gems - see https://travis-ci.org/google/protobuf/builds/163625616 for details
`System.identityHashCode` returns a hash that does not consider a
Message's values. This means two Messages with identical values will not
have identical hashCodes.
This patch uses the pattern from RubyMap to combine the hashCodes from
all values in a given message and produce a unique, consistent,
value-based hash.
