setup.py missing install_requires on jinja2, protobuf
fastpb is missing dependency declarations in its setup.py file, which makes it harder to use inside a virtualenv.
To get things running I had to install jinja2 and protobuf. Things should work if you add them as a install_requires kwarg to the setup() call:
install_requires=["jinja2", "protobuf"]enum in a nested message doesn't appear to get set
If I have a definition like so:
enum Status {
IN_PROGRESS = 1;
ERROR = 2;
}
message Foo {
message Bar {
optional Status status = 1;
}
optional Bar bar = 1;
}
And code like so:
foo = Foo()
foo.bar = Foo_Bar()
foo.bar.status = Status.IN_PROGRESS
print foo.bar.statusNone is printed instead of 1. Things work ok if I move the status field from the inner Bar message to the outer Foo.
Members of a list become disassociated when you mutate them
Say you have a protocol buffer that contains a repeated element which in turn contains more repeated elements. If you mutate one of the repeated elements at the root, you're fine. However, if you mutate a repeated element that is a child of another repeated element, it becomes a different object from the one that's in its parent's list.
This demonstrates how the same object gets dissociated
nested_item = Top.items[0]
nested_item.items += (item,)
nested_item.items.length != Top.items[0].items.length
This quickly demonstrates the anomaly and how it eats data
length_before = Top.items[0].items.length
Top.items[0].items += (item,)
length_after = Top.items[0].items.length
length_before == length_after
incompatibility - empty optional attributes are None instead of not existing
When parsing a message, optional attributes which don't have a value are created with a None value.
This is incompatible with the Google implementation, which does not create the attribute at all.
BTW this tool is great - keep up the good work :-)
KeyError from protoc
Here's what I get when trying to compile my *.proto file:
protoc --fastpython_out=. --cpp_out=. --proto_path=. messages.proto
Traceback (most recent call last):
File "/usr/local/bin/protoc-gen-fastpython", line 9, in <module>
load_entry_point('fastpb==0.1', 'console_scripts', 'protoc-gen-fastpython')()

return [msgDict[n] for n in sortedMsgNames]
KeyError: u'.Event'
--fastpython_out: protoc-gen-fastpython: Plugin failed with status code 1.
make: *** [messages_pb2.py] Error 1
And here's the content of messages.proto:
message Event {
optional fixed64 id = 1;
optional bytes hashcode = 2;
optional int32 severity = 3;
optional int32 facility = 4;
optional string message = 5;
optional string host = 6;
optional string program = 7;
optional string cisco_mnemonic = 8;
optional fixed64 first_occurence = 9; // This is unix time in us (time() * 1e6)
optional fixed32 duration = 12; // last_occurence = first_occurence + duration
optional fixed32 counter = 13;
repeated fixed32 extra_ipv4 = 20;
repeated bytes extra_ipv6 = 21;
repeated string extra_string = 22;
repeated int32 extra_int32 = 23;
enum MessageType {
NEW = 0;
UPDATE = 1;
};
optional MessageType message_type = 50 [ default = NEW ];
}
message EventPack {
repeated Event events = 1;
}
option optimize_for = SPEED;
Any ideas?
BTW, with --python_out it works fine.
Licensing needs clarification
It looks like the project is meant for general consumption (eg: not internal) and has been advertised as such in several places. However, several people have pointed out there's no license terms given anywhere. What is it? BSD? GPL? Or not meant to be used by others?
Nested enums don't have a python object created
If you next an enum inside an object, like so:
message Foo {
message Bar {
enum Quux {
NAH = 0;
YEAH = 1;
}
optional Quux quux = 1;
}
optional Bar bar = 1;
}
It never is placed into the enums list, and the Python object is never constructed for it.
