after attempting to encode broken input (null instead of arrayref) the encoder breaks for all subsequent encode() calls
so having schema like:
message Person {
required int32 id = 1;
repeated SomeSubMessage foo = 6;
message SomeSubMessage {
repeated int32 arrayOfInts = 2;
}
}
after attempt to encode {id => 123, foo => [{arrayOfInts => undef }]}
, all subsequent encode()
calls produce 0 byte outputs
encoded length: 4
Not an array reference when encoding field 'humans.Person.SomeSubMessage.arrayOfInts' at ff20.pl line 31.
encoded length: 0
encoded length: 0
encoded length: 0
script to reproduce:
use Data::Dumper;
use Google::ProtocolBuffers::Dynamic;
$dynamic = Google::ProtocolBuffers::Dynamic->new;
$dynamic->load_string("person.proto", <<'EOT');
syntax = "proto2";
package humans;
message Person {
required int32 id = 1;
repeated SomeSubMessage foo = 6;
message SomeSubMessage {
repeated int32 arrayOfInts = 2;
}
}
EOT
$dynamic->map({ package => 'humans', prefix => 'Humans' });
toggle({id => 123, foo => [{}]});
toggle({id => 123, foo => [{arrayOfInts => undef }]});
toggle({id => 123, foo => [{}]});

my $encoder = "Humans::Person";
eval {

print "encoded length: ". length($bytes) . "\n";

it works fine if arrayOfInts is in the top object"

Just built with protobuf from github and get the following warnings:
[libprotobuf WARNING google/protobuf/compiler/parser.cc:547] No syntax specified for the proto file: scalar.proto. Please use 'syntax = "proto2";' or 'syntax = "proto3";' to specify a syntax version. (Defaulted to proto2 syntax.)
Probably doesn't matter yet, but eventually will. :)
(Sorry for not just patching this.)
The documentation says:
$dynamic = Google::ProtocolBuffers::Dynamic->new($search_path);
Please explain what EXACTLY goes in $search_path. How do I specify more than one path? I have my project .proto file(s), and they import google .proto files such as timestamp.proto...
Logs attached.
I believe upb supports JSON in- and output transparently while using the same protobuf schemas. I think as a not-protobuf-enabled-client compatibility layer, supporting this in GPB::Dynamic as something like encode_json/decode_json for the generated mapper classes would be awesome.
(And yeah, I have a work use case in mind for that.)
I cannot make two .proto's to work.
=== Address.proto ===
package Diadoc.Api.Proto;
message Address {
optional RussianAddress RussianAddress = 1;
optional ForeignAddress ForeignAddress = 2;
optional string AddressCode = 3;
}
message RussianAddress {
optional string ZipCode = 1;
required string Region = 2;
optional string Territory = 3;
optional string City = 4;
optional string Locality = 5;
optional string Street = 6;
optional string Building = 7;
optional string Block = 8;
optional string Apartment = 9;
}
message ForeignAddress {
required string Country = 1;
required string Address = 2;
}
=== Address.proto ===
=== Organization.proto ===
import "Address.proto";
package Diadoc.Api.Proto;
//...
message Department {
required string DepartmentId = 1;
required string ParentDepartmentId = 2;
required string Name = 3;
optional string Abbreviation = 4;
optional string Kpp = 5;
optional Address Address = 6;
optional bool IsDisabled = 7 [default = false];
}
//...
=== Organization.proto ===
Every attempt I was able to imagine yields an error
Error processing serialized protobuf descriptor: Organization.proto: Import "Address.proto" has not been loaded.
Error processing serialized protobuf descriptor: Organization.proto: ".Diadoc.Api.Proto.Address" is not defined.
Looks like either your module does not handle import properly or I'm doing some quite simple error
TBD whether they should create a fresh array every time or store it on first fetch.
Also check this does not change the behaviour of other list accessors.
For example the mysqlx protocol definition at https://github.com/mysql/mysql-server/tree/5.7/rapid/plugin/x/protocol requires separate mappings for Mysqlx, Mysqlx.Connection, ...
which is suboptimal.
This seems to be related to the new boolean values introduces in 5.36.0 and the changes in how Data::Dumper stringifies these starting with 5.37.2. See DrHyde/perl-modules-Test-Differences#21 for more context on this issue.
FYI, I was able to get past the below error by doing export CFLAGS="-std=c++11 -O3"

Hi, I noticed that one of my scripts is leaking memory, and after investigating it seems that the G::PB::D is the reason. Consider the following script:
#!/usr/bin/env perl
use 5.014;
use strict;
use warnings;
use Google::ProtocolBuffers::Dynamic;
my $dynamic = Google::ProtocolBuffers::Dynamic->new;
$dynamic->load_string( "person.proto", <<'EOT');
syntax = "proto2";
package humans;
message Person {
required string name = 1;
required int32 id = 2;
optional string email = 3;
}
EOT
$dynamic->map(
{
package => 'humans',
prefix => 'Humans'
}
);
for ( 1 .. 100000 ) {
my $bytes = Humans::Person->encode(
{
name => 'foo',
id => 42
}
);
}
when running it under valgrind I'm getting the following output (with some of it skipped):

The problem is present starting from module version 0.15.
The pod documentation says to call load_string($string) but I get error message showing three arguments. What are the arguments?
Usage: Google::ProtocolBuffers::Dynamic::load_string(THIS, file, sv) at bin/proto-to-module.pl line 14.
Here is my program:
use Google::ProtocolBuffers::Dynamic;
my $s = q/ message Person { required string name = 1; } /;
my $dynamic = Google::ProtocolBuffers::Dynamic->new;
$dynamic->load_string($s);
Encoding/decoding roundtrip via protobuf or JSON does produce a different result when the set value is 0. See the the following code for a failing testcase

Tested with version 0.16 and perl 5.22.3
We have messages that contain sometimes empty string values, I would expect them to be decoded as empty strings, but we're getting undef
instead. I added a test to demonstrate the problem here: e020d6b
Would be nice to have a way to resolve protobuf message names to the perl classes they are mapped to at runtime. So if I have a protobuf bytes blob and I know the protobuf message name for it, I could feed it to the appropriate perl class for decoding. For example $dynamic->resolve_message($protobuf_name)
would return the perl class mapped to it.
Use case: I'm toying around implementing twirp support for perl, and basically mimicking what they do for their python support. Python protobuf stuff has a symbol db that can be used to look up things like this. For encoding there's no need for that as the given perl object can just be told to ->encode
itself, but for decoding I'd need to have a class to feed the bytes to.
It's possible to map enum keys that are also keywords in the main:: package
$ cat PB_evil_enums.pm
package PB_evil_enums;
use strict;
use warnings;
use Google::ProtocolBuffers::Dynamic;
my $gpd = Google::ProtocolBuffers::Dynamic->new;
$gpd->load_string('', <<'EOD');
syntax = "proto2";
package evilenum_pb;
message console_log_line {
// from: https://perldoc.perl.org/constant#CAVEATS
enum perl_keywords {
STDOUT = 1;
STDERR = 2;
}
optional perl_keywords the_enum = 1;
}
EOD
$gpd->map(
+{
'package' => 'evilenum_pb',
'prefix' => 'PB_evil_enums::_pb'
},
);
print STDERR "STDERR is okay from module\n";
undef $gpd;
1;
loading this module causes misattributed errors when compiling subsequent scripts & modules:
$ perl -e 'print STDERR "hi"';
hi
$ perl -I. -MPB_evil_enums -e 'print STDERR "hi"';
STDERR is okay from module
String found where operator expected at -e line 1, near "STDERR "hi""
(Do you need to predeclare STDERR?
this error is due to main::STDERR being converted from a fileglob to a constant sub:
$ perl -I. -MPB_evil_enums -e 'print STDERR()';
STDERR is okay from module
2
Perhaps src/dynamic.cpp: Dynamic::map_enum()
should be dying on any enum field named with a known perl keyword, or prefixing/suffixing those words with some special string to avoid the collision (but perhaps cause another?).
I don't speak C++ so this looks very cryptic to me, but using g++ 4.9.2 on Debian Jessie with protobuf 3.5.1 freshly compiled and installed, the build errors out. GCC is unhappy about 4 properties being constant without there being an explicit assignment overload method:

Hi! I'm reporting this here in case anyone else stumbles on this issue.
I notice that I have to use X.pm
(generated by protoc
) as early as possible in my program flow in order to avoid that warning, which I'm hoping is benign.
That said, with Apache/mod_perl I cannot get rid of that warning every time a new Apache child is forked. I tried using the module in my handler.pl
, and even in the Apache configuration itself in PerlModule
, PerlLoadModule
, PerlRequire
, PerlPostConfigRequire
.
The only places I found CHECK
in /usr/
were in ExtUtils/XSpp/Grammar.pm
and this module's Dynamic.so
. I'm not too sure how to investigate this further. There doesn't seem to be a way to look at generated code since it's generated dynamically at module load time.
Try to use protoc-gen-perl-gpd to generate module but the script never exits and prints warnings.

Version of Google::ProtocolBuffers::Dynamic is 0.32.
Version of perl is 5.34.
if I map a proto before launching-and-joining two threads (or join just one thread and then exit the main process), I get warning outputs from glibc and a coredump:
#!/usr/bin/perl
use strict;
use warnings;
use threads;
use Google::ProtocolBuffers::Dynamic;
my $dynamic = Google::ProtocolBuffers::Dynamic->new;
$dynamic->load_string("person.proto", <<'EOT');

package humans;
message Person {
required string name = 1;
required int32 id = 2;
optional string email = 3;
}
EOT
$dynamic->map({ package => 'humans', prefix => 'Humans' });
for (1..2) {
my $thr = threads->create({'context' => 'list', 'exit' => 'thread_only'}, sub {
my $tid = threads->tid();
warn "new thread: $tid";
return $tid;
});
}
my @results = map { $_->join(); } threads->list();
warn "joined threads: @results";

this may be too simple of a fix for users that detach threads instead of joining them. but I think that leaking is preferable to double-freeing and crashing out.
fwiw my application does not use protos in its threads but spawns them upfront for auxiliary chores. I've resorted to requiring my protos' generated modules after these threads have been spawned but this may not be doable in many applications, either because they wish to preload all code or because they spawn threads intermittently after a mapping may have been done.
The underlying upb
library provides const_field_iterator
which is used in mapper.cpp
to iterate over FieldDef
s and field information is stored in that order in a fields
vector.
Later, const_oneof_iterator
is used to iterate over the "oneof" fields, and field_def->index()
is used to access the fields vector to delete any existing value for the "oneof".
The presumption here is that field_def->index()
is usable to index the list of fields returned by const_field_iterator
in the order they're returned.
This presumption turns out not to be correct. The question is, what is correct?
Should upb's const_field_iterator
return fields in field_def->index()
order?
Or is field_def->index()
really unrelated to the order that const_field_iterator
returns fields in, and Mapper::Mapper()
should use field_def->index()
to populate the vector of fields?
To recreate this issue:
tim.proto:
syntax = "proto3";
message A {
int32 val = 1;
oneof foo {
B b = 2;
C c = 3;
}
message B {
int32 val = 1;
}
message C {
int32 val = 1;
}
}
tim.pl:
#!/usr/bin/perl
use strict;
use warnings;
use 5.008;
use Google::ProtocolBuffers::Dynamic;
my $dynamic = Google::ProtocolBuffers::Dynamic->new( '.' );
$dynamic->load_file( 'tim.proto' );
$dynamic->map( { message => 'A', to => 'A' } );
my $json = '{"val":5,"b":{"val":6}}';
my $data = A->decode_json( $json );
print "A.val = ".$data->get_val."\n";
output:
$ ./tim.pl
A.val = 0
epected output:
$ ./tim.pl
A.val = 5
This happens because, when decoding "b":{"val":6}
, the Field
definition for b
has a oneof_index
which causes the decoder to look for any existing value in that "oneof" group, which will need to be deleted. Unfortunately, the initial "val":5
field definition also says it's in the same "oneof" group, and so A.val
is deleted.
The oneof_index
es are set up incorrectly in Mapper::Mapper()
, when iterating over the oneof groups. The following code in mapper.cpp
is where that happens:
for (OneofDef::const_iterator it = oneof_def->begin(), en = oneof_def->end(); it != en; ++it) {
const FieldDef *field_def = *it;
Field &field = fields[field_def->index()]; // <-- CAN PICK WRONG FIELD
field.oneof_index = oneof_index;
}
What is the correct fix? A change in mapper.cpp
? Or a change in upb?

A nice error message would be better
Unless I'm missing something, there doesn't appear to be a very convenient method to map a message that uses message types defined in other packages.
E.g., suppose you have these two proto
files:
a.proto:
syntax = "proto3";
package a;
import "b.proto";
message A {
b.B foo = 1;
}
b.proto:
syntax = "proto3";
package b;
message B {
string bar = 1;
}
And you wanted to map a.A
, you might go as follows:
$dynamic->load_file( "a.proto" );
$dynamic->map( { message => 'a.A', to => 'PB' } );
But this raises the following error (actually from resolve_references()
):
Unknown type 'b.B'
It may not always be convenient to map b.B
first. For example, in the case where you are writing a generic tool, you may not know that you have to. It would be significantly more convenient to be able to load a message and map anything it needs to a perl package prefix.
The order of vector cleanup in Mapper::DecoderHandlers::on_end_sub_message()
can cause the seen_oneof
vector to be pop()
ed too many times.
