[protobuf] Re: Issue 574 in protobuf: generated header function ::mutable_ attempts to initialize by dereferencing an uninitialized default
Comment #1 on issue 574 by sizefi...@gmail.com: generated header function ::mutable_ attempts to initialize by dereferencing an uninitialized default http://code.google.com/p/protobuf/issues/detail?id=574 Ooops tried to abstract the version field name with 'myfield' in the example code above and missed a couple entries before submitting... yes, myfield was actually version. Here's the proto line entry... required string version = 1 [default="0.0.0.0"]; -- You received this message because this project is configured to send all issue notifications to this address.

[protobuf] Issue 574 in protobuf: generated header function ::mutable_ attempts to initialize by dereferencing an uninitialized default
Status: New
Owner: liuj...@google.com
Labels: Type-Defect Priority-Medium
New issue 574 by sizefi...@gmail.com: generated header
function ::mutable_ attempts to initialize by dereferencing an
uninitialized default
http://code.google.com/p/protobuf/issues/detail?id=574
What steps will reproduce the problem?
1. Create a global class instance whose constructor calls GPB's
ParseFromArray on GPB object
2. ParseFromArray will attempt to initialize values to defaults
3. Default has not yet been assigned, e.g. _default__ is null
What is the expected output? What do you see instead?
_ value should be defaulted, instead an access violation error
occurs (from new ::std::string(*null)) where _default is unassigned.
What version of the product are you using? On what operating system?
2.5.0 on Windows 7 64-bit (32-bit build of GPB), VS2012 SP1
Please provide any additional information below.
The timing of global and static object construction will ultimately affect
whether or not this violation happens. I was able to avert disaster by
checking for null on _default_version_ however it forced me to not assign
the default. This probably may not be easily replicated unless static GPB
initializers happenstance execute after the global object is created.
// this is the generated function in the C++ header:
inline ::std::string* mytype::mutable_myfield() {
set_has_myfield();
if (version_ == _default_myfield_) {
version_ = new ::std::string(*_default_myfield_);
}
return myfield_;
}
// this is the generated function in the C++ implementation which
// is supposed to initialize the defaults, but happens after the above
// is called.
void protobuf_AddDesc_mytype_2eproto();

You just run the protoc binary directly to compile .proto files. Like other command line tools, "protoc --help" will give you some helpful information on how to run the tool. -- You received this message because this project is configured to send all issue notifications to this address.
