Hi,
I am debugging a core file in gdb and I have the raw encoded data of a
message. I want to decode this message to see the values. I tried using
--decode_raw with no success. Here is what I am doing
(gdb) p $12->send_ctx_.parts[0]
$23 = {_ = "0?)\224\002\177", '\000' <repeats 25 times>, "\200"}
(gdb) p $12->send_ctx_.parts[1]
$24 = {_ = "\000M0\224\002\177", '\000' <repeats 25 times>, "\200"}
parts is an array of serialized messages. Now I try
vagrant@dev-01:~$ protoc --decode_raw
0?)\224\002\177
Failed to parse input.
I tried adding that data in a file and tried giving that as input
protoc --decode_raw < ~/data.txt
Failed to parse input.
I thought maybe I need to \000 repeated 25 times followed by a \200 so I
tried with that as well and still no luck. I then tried to use the decode
instead of decode_raw option by specifying the proto path and the proto
file and the message name but it still did not work.
I then tried to encode some data and decode it back to see if it works. I
entered the values in text form in a file
error:OUT_OF_MEMORY,object_id:123,size:4096
these are all valid values. I then ran the --encode option specifying the
proto path and file
protoc --proto_path=/path_to_proto_dir /path_to_proto_dir/proto_file.proto
--encode=MessageName < ~/proto.txt
?{?
I copied the text as is in to a file and rand --decode on it and it fails
with 'Failed to parse input". What am I missing ? How do I use the
decode_raw or decode option ? Is there a format the data has to be in for
it to be decoded ?
Thanks,
Vinay
