The protobuf common.h header currently has a "using std::string;"
statement that pulls std::string into the google::protobuf namespace:
ce66f6047d/src/google/protobuf/stubs/common.h (L195)
I plan to delete that line soon. To keep protobuf-c working, this commit
updates the generator to fully qualify std::string.
The protobuf project removed "using namespace std" namespace pollution
from their stubs/common.h header file. This caused build failures for us
since we relied on their namespace pollution.
This commit updates protobuf-c to convert:
'map' → 'std::map'
'set' → 'std::set'
'back_insert_iterator' → 'std::back_insert_iterator'
This is a first cut at adding proto3 support.
As far as I understand protobuf-c already has pretty much everything
needed once it is built using a new version of protobuf itself.
The only missing thing is that in proto3 all fields are optional and
having to manually set has_foo is inconvenient.
This patch special cases the proto3 syntax files so that structs for the
bytes, enum and primitive fields do not emit the has_ field.
It also adds PROTOBUF_C_LABEL_NONE to the label enum that is used for
proto3 fields. When a fields has this label, the quantifier is not
consulted and instead the field is packed/unpacked depending on
whether it has a value different from NULL/0.
per https://code.google.com/p/protobuf/source/detail?r=50, the license
on google-originated protobuf code was switched from Apache-2.0 to
BSD-3-Clause (so-called "New BSD" license). update any of the google
license statements to use this new license.
per email with dave, drop the third clause on his BSD-3-Clause license,
so this now becomes BSD-2-Clause.
make sure to use consistent indentation and wrapping throughout.
