a55b869305 implement MessageBuilder.unsafeConstructFromMessageReader() 2021-05-24 13:06:42 -04:00
David Renshaw
a078df7e4d add support for directly serializing a MessageReader 
Previously, you would need to copy the message into a MessageBuilder first.

4ec14e39f9 be more careful about integer overflow in Serialize.read() 
Previously, we were attempting to read the entire message
in one call to fillBuffer(). This was doomed to fail
if the message had more than Integer.MAX_VALUE bytes.

After this diff, we will call fillBuffer() separately for each
segment. This approach turns out to be simpler, too.
It might imply a small performance hit for messages with
many small segments, but such messages are discouraged anyway.

This diff also adds more overflow checking in the surrounding
logic.

eb73990798 fix potential overflow in DefaultAllocator 
Fixes a bug where the allocator's `nextSize` variable could overflow
and become negative, causing more segments to be allocated than expected.

Also removes a duplicate `this.nextSize += size` statement that
likely made the problem worse.

cc4fa2bbc8 Offer option to disable traversalLimitInWords 
Use case: large trusted input data file, mapped in memory by
MappedByteBuffer, which is often re-queried so a sensible
limit cannot be set.

d2634a21d0 Support reading all segments from a single ByteBuffer, with tests 
Sometimes it is desirable to read all segments from a single ByteBuffer,
e.g. if reading messages from a memory-mapped file.

Here we add such support, and add a test to check that the ByteBuffer
read behaves the same as the ReadableByteChannel read.
