kandi X-RAY | protobuf-c Summary
This is protobuf-c, a C implementation of the Google Protocol Buffers data serialization format. It includes libprotobuf-c, a pure C library that implements protobuf encoding and decoding, and protoc-c, a code generator that converts Protocol Buffer .proto files to C descriptor code, based on the original protoc. protobuf-c formerly included an RPC implementation; that code has been split out into the protobuf-c-rpc project.

QUESTION
I'm trying to run makefile command 'gen' from this project https://github.com/penthaapatel/grpcblog. The command is: protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative blog/blog.proto
However I get an error:
ANSWER
Answered 2021-May-02 at 14:21So I deleted github.com/golang/protobuf

QUESTION
Here's the situation: I have a Firestore Database. I download it on a daily basis to a Google Cloud Storage Bucket as a backup. If I want to download it locally, I do it using this command gsutil -m cp -r gs://BUCKET_PATH "DESTINATION_PATH"
and it works fine.
MY PROBLEM: the format of the Bucket I download is LevelDB (I think). On my machine, it looks like this :
For example, this is my /users
collection in Firestore when I download it through Google Storage. In the folder, I have multiple binary files ("output-...") and a file ( here: "all_namespaces_kind_users") for metadata.
MY GOAL: I want to be able to read my database in a json file.
MY TRIES:
- I try to use this convertor : https://github.com/Venryx/firestore-leveldb-tools but it uses Python2 and some old google libraries. Using this convertor, I have to download the SDKs locally (see below).
ANSWER
Answered 2021-Apr-26 at 22:53I have created a converter in Python 3 which could convert firestore export files into JSON files firestore-export-json. The package provides a simple CLI command to covert the file.

I need a specific version of protocol buffer which is 3.14.0
on apt its not available like this
ANSWER
Answered 2021-Mar-19 at 06:06I think Because /usr/bin/protoc doesn't exist. When you unzipped you got folder named protoc-3.14.0. which is /usr/bin/protoc-3.14.0

For full transparency, I started learning about Cucumber an hour ago. I've been following a concise tutorial on using Selenium in Ruby with Cucumber and I've had no issues until this point.
In essence, I'm trying to run a test scenario(?) but I am receiving this error:
...ANSWER
Answered 2021-Mar-18 at 15:18This is a RubyMine bug. Nothing we can fix on the Cucumber end.
You can either consult a non-recommended monkeypatch / hack. Or downgrade to an early version of Cucumber5.
See https://youtrack.jetbrains.com/issue/RUBY-27294 for more information, including other possible workarounds and a time-frame for the fix from Jetbrains.

QUESTION
Using the official golang
docker image, I can use the protoc
command to generate the x.pb.go
and x_grpc.pb.go
files. The problem is that it uses the latest versions, while I want to generate those using whichever version that is part of the go.mod
file.
I tried to start from the golang
image, then get my project's go.mod
file, get the dependencies and try to generate from there. Here is my dockerfile:
ANSWER
Answered 2021-Feb-25 at 16:53go.mod
& go.sum
are used for versioning when building go
programs. This is not what you need here. You want the protoc
compiler to use the correct plugin versions when running it against your .proto
file(s).
To install the desired protoc-gen-go
(and protoc-gen-go-grpc
if using gRPC) plugins, install them directly. Update your Dockerfile
like so:

Inside docker, it seems that I cannot compile my gRPC micro-service due to this error:
...ANSWER
Answered 2020-Sep-07 at 00:39The gist of this error is that the version of binary used to generate the code isn't compatible with the current version of code. A quick and easy solution would be to try updating the protoc-gen-go
compiler and the gRPC library to the latest version.
go get -u github.com/golang/protobuf/protoc-gen-go

QUESTION
I'm working on OSX and have postgres installed via Homebrew. I've just upgraded Postgres from v11 to v13. Now I've tried updating the database files with:
...ANSWER
Answered 2020-Nov-13 at 03:28Upgrading PostGIS is not so straightforward (see the documentation), and by using the automatic upgrade of this distribution you probably messed up your installation.
Take a full backup of your PostgreSQL data directory, then uninstall PostgreSQL v13, install v11 and PostGIS 2.5 again and see that you can get the database to work again.
Then follow the upgrade procedure from the PostGIS manual.
QUESTION
When I build a protobuff for arm and then install it, I don't see *.so
files in the lib/ directory, only *.a
and *.la
. If I build it for x86, then everything is fine.
The sequence of commands is as follows:
...ANSWER
Answered 2020-Dec-12 at 07:24You are mixing up --host
, --build
, and --target
. The --host
option designates the machine type on which the artifacts you are building will run. The --build
option designates the machine type on which you are performing the build, and you do not ordinarily need to specify it, because the build system can guess. In fact, that's the whole purpose of the auxilliary script config.guess
, which should be included in the protobuf distribution. The --target
option applies only when the thing you are building is itself a cross tool; it designates the machine type for binaries that the built tool itself works with.
Having set those correctly, you probably do not need to explicitly specify the C and C++ compilers -- configure
should figure them out from the host triplet. (The appearance of the host triplet in the cross tools' names is not a coincidence.)
Additionally, it would be more semantically correct to use DESTDIR
at installation time than to use a --prefix
at configure
time. It may make a genuine difference, too, because the specified prefix is sometimes compiled into the built binaries.
Also, as a side note, use sudo
only at the install step, not the configuration and build steps. It's safer that way, and it doesn't leave root-owned debris behind in the build directory. But you don't need it even then if you're installing into a directory on which you have write privileges, as you appear to be doing in your example commands.
Thus:
