+Make ./snappy_unittest pass without "srcdir" being defined.
+
+Previously, snappy_unittests would read from an absolute path /testdata/..;
+convert it to use a relative path instead.
+
+Patch from Marc-Antonie Ruel.

+Increase the Zippy block size from 32 kB to 64 kB, winning ~3% density
+while being effectively performance neutral.
+
+The longer story about density is that we win 3-6% density on the benchmarks
+where this has any effect at all; many of the benchmarks (cp, c, lsp, man)
+are smaller than 32 kB and thus will have no effect. Binary data also seems
+to win little or nothing; of course, the already-compressed data wins nothing.
+The protobuf benchmark wins as much as ~18% depending on architecture,
+but I wouldn't be too sure that this is representative of protobuf data in
+general.
+
+As of performance, we lose a tiny amount since we get more tags (e.g., a long
+literal might be broken up into literal-copy-literal), but we win it back with
+less clearing of the hash table, and more opportunities to skip incompressible
+data (e.g. in the jpg benchmark). Decompression seems to get ever so slightly
+slower, again due to more tags. The total net change is about as close to zero
+as we can get, so the end effect seems to be simply more density and no
+real performance change.
+
+The comment about not changing kBlockSize, scary as it is, is not really
+relevant, since we're never going to have a block-level decompressor without
+explicitly marked blocks. Replace it with something more appropriate.
+
+This affects the framing format, but it's okay to change it since it basically
+has no users yet.
+
+
+Density (note that cp, c, lsp and man are all smaller than 32 kB):

+Change a few ORs to additions where they don't matter. This helps the compiler
+use the LEA instruction more efficiently, since e.g. a + (b << 2) can be encoded
+as one instruction. Even more importantly, it can constant-fold the
+COPY_* enums together with the shifted negative constants, which also saves
+some instructions. (We don't need it for LITERAL, since it happens to be 0.)
+
+I am unsure why the compiler couldn't do this itself, but the theory is that
+it cannot prove that len-1 and len-4 cannot underflow/wrap, and thus can't
+do the optimization safely.
+
+The gains are small but measurable; 0.5-1.0% over the BM_Z* benchmarks
+(measured on Westmere, Sandy Bridge and Istanbul).

+Handle the case where gettimeofday() goes backwards or returns the same value
+twice; it could cause division by zero in the unit test framework.
+(We already had one fix for this in place, but it was incomplete.)
+
+This could in theory happen on any system, since there are few guarantees
+about gettimeofday(), but seems to only happen in practice on GNU/Hurd, where
+gettimeofday() is cached and only updated ever so often.
