Public bug reported:
Imported from Debian bug http://bugs.debian.org/1070785:
Package: libsnappy-dev
Version: 1.2.0-2
Severity: important

Dear Maintainer,
The patch added to restore older API signatures to resolve Bug 1070217
creates ambiguity in the method signatures resulting in FTBFS in at
least the ceph package:
In file included from
/<<PKGBUILDDIR>>/src/compressor/snappy/CompressionPluginSnappy.h:20,
from
/<<PKGBUILDDIR>>/src/compressor/snappy/CompressionPluginSnappy.cc:20:
/<<PKGBUILDDIR>>/src/compressor/snappy/SnappyCompressor.h: In member function
‘virtual int SnappyCompressor::compress(const ceph::bufferlist&,
ceph::bufferlist&, std::optional<int>&)’:
/<<PKGBUILDDIR>>/src/compressor/snappy/SnappyCompressor.h:68:21: error: call of
overloaded ‘Compress(BufferlistSource*, snappy::UncheckedByteArraySink*)’ is
ambiguous
68 | snappy::Compress(&source, &sink);
| ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~

Sink*)’

Sink*, CompressionOptions)’

make[3]: *** [src/compressor/snappy/CMakeFiles/ceph_snappy.dir/build.make:79:
src/compressor/snappy/CMakeFiles/ceph_snappy.dir/CompressionPluginSnappy.cc.o]
Error 1
make[3]: Leaving directory '/<<PKGBUILDDIR>>/obj-x86_64-linux-gnu'
make[2]: *** [CMakeFiles/Makefile2:7668:
src/compressor/snappy/CMakeFiles/ceph_snappy.dir/all] Error 2
The compression options parameter which was added for >= 1.2 of snappy
provides a default, so the added method with no options creates this
ambiguity.
Thanks!
