> C++ TJSONProtocol using locale dependent formatting
> ---------------------------------------------------
>
> Key: THRIFT-2870
> URL: https://issues.apache.org/jira/browse/THRIFT-2870
> Project: Thrift
> Issue Type: Bug
> Components: C++ - Library
> Affects Versions: 0.9
> Environment: Linux, Boost 1.51
> Reporter: Simon Falsig

> I'm using Thrift for serializing objects (in C++) into JSON strings, which I
> then store as files. This usually works fine, but if the locale of my system
> is set to a locale where the decimal separator is ',' instead of '.' (for
> instance in Denmark), then the TJSONProtocol (specifically the
> writeJSONDouble function that does the double to string conversion through a
> boost::lexical_cast) will also use this separator when serializing doubles.
> This kinda plays havoc with the JSON specification, which does not allow for
> localized formatting, and depends on always using '.' as a decimal separator.
> I could imagine that there may be other more subtle places where the local
> can have an effect, but this is currently the only place I've been having
> trouble with.
> I can see that the same problem has been fixed for C# (commit
> 3da317bda100130b2f615034c46b0944888f0f14 / THRIFT-1245 C# JSON Protocol uses
> culture-dependant decimal separator for double) but it doesn't seem as if
> there's a similarly easy way to fix boost::lexical_cast...
> Note that I'm using Thrift 0.9.0, but as far as I can see there hasn't been
> any relevant changes to TJSONProtocol.cpp since.
> Relevant thread on thrift-user mailing list can be found here:
> http://mail-archives.apache.org/mod_mbox/thrift-user/201412.mbox/%[email protected]%3e
> I've also attached a quick patch that works on my setup (see the patch file
> comments for more information).
