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:
5098508d2d/src/core/lib/support/wrap_memcpy.c
This fixes issue #2783.
* 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.
* 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.
1. Added ruby22 and jruby tests to jenkins.
2. Added javascript tests to jenkins.
3. Added golang tests to jenkins.
4. Removed ruby19/ruby20 tests from travis. Support for ruby 2.0 has
ended since 2016/02/24.
