Subject [jira] [Commented] (THRIFT-1727) Ruby-1.9: data loss: "binary" fields are re-encoded
Date Wed, 14 Nov 2012 22:32:12 GMT


Nathan Beyer commented on THRIFT-1727:

I think that may be part of the solution, but in looking at the other libraries, I think we
need to just enhance the protocol classes to support 'write_binary'/'read_binary' methods
and implement usage of those methods.

> When setting a binary field of a Thrift object with some binary data (e.g. a string whose
encoding is "ASCII-8BIT") and then serializing this object, the binary data is re-encoded.
That is, it is encoded as if it were not a sequence of bytes but a sequence of characters,
encoded using the ISO-8859-1 encoding. This assumed ISO-8859-1 sequence of characters is then
converted into UTF-8 (by BinaryProtocol or CompactProtocol). This basically means that all
bytes whose values are between 0x80 (inclusive) and 0x100 (exclusive) are converted into multi-byte
sequences. This leads to data corruption.
