/On success the value of maxfd is guaranteed to be >= -1. We call select(maxfd + 1, ...); specially in case of (maxfd == -1) there are no fds ready yet so we call select(0, ...) --or Sleep() on Windows-- to sleep 100ms, which is the minimum suggested value in the curl_multi_fdset() doc./

Installed latest sdk on updated Ubuntu 18.04.6 LTS, 5.4.0-52-generic via vcpkg install minio-cpp. Compiling the example OK, but running it results in nothing and no error no matter what credentials, however - wrong url results in error. Populated storage according to https://github.com/minio/mc/releases without any issues. Any ideas?

Hi，I have an SDK request problem，I use the following code, return “MakeBucket(): invalid response received; status code: 400; content-type: text/xml; charset=utf-8”，You know why?

code: minio::s3::MakeBucketArgs args1; args1.bucket = "test"; minio::s3::MakeBucketResponse resp1 = client.MakeBucket(args1); if (!resp1) { throw std::runtime_error("MakeBucket(): " + resp1.Error().String()); }

I tried to install miniocpp with vcpkg on my mac M1 and when I look at the include folder in miniocpp (~/vcpkg/installed/arm64-osx/include/miniocpp) I can only see the following:

├── s3.h ├── s3_headers.h ├── s3_http.h ├── s3_io.h ├── s3_signature_v2.h └── s3_types.h

This doesn't match with what's on the repository. Is it because the version is outdated?

Dear, I see that minio::s3::Client create new http connections for each operation. That will consume much ports in high concurrency scenario.

So, I want to reuse the http connection to avoid that problem. How can I do?

many thanks.

Unable to build due to: CMake Error at CMakeLists.txt:57 (find_package): Could not find a package configuration file provided by "unofficial-curlpp" Cannot find package on linux

I compiled the library in Windows 10 vs 2019;

Error message is displayed: “arpa/inet.h”: No such file or directory

This file appears to be for the Linux platform, whether the library can be compiled on Windows

Hello,

I am reaching out in regards to support of C language, how viable is it in your opinion? Are there any plans of having C SDK of minio or at least a header wrapper for C that will be linked to CXX library via minio-cpp?

Thank you !

I refer to the above file and I get an error when I execute PutObject"： server failed with HTTP status code 0

In http.h line 127 there is a sockaddr_in, which is an IPv4 sockaddr, but in the following line it gets filled with an IPv6 address, which needs more space than an IPv4 address It should be sockaddr_in6 for that purpose.

Recommended to use vcpkg as a 3rd lib manager.

1. adapt to windows msvc (2019+): add src/win/getopt.h
2. use vcpkg instead of traditional find_package
3. remove curlpp submodule, also use vcpkg

just replace 'i < 3' to 'i < 1010' in tests/tests.cc:390 at method test.ListObjects and you get it: Program terminated with signal SIGSEGV, Segmentation fault.

Trouble at

sed -n "36,40p" src/client.cc

36    args_->marker = resp_.next_marker;
37  } else {
38    args_->start_after = resp_.start_after; // <- trouble at this line
39    args_->continuation_token = resp_.next_continuation_token;
40  }

The reason of trouble at src/client.cc:669:

minio::s3::ListObjectsResult minio::s3::Client::ListObjects(
    ListObjectsArgs args) {
   if (error::Error err = args.Validate()) return err;
  return ListObjectsResult(this, args);
 }

minio::s3::Client::ListObjects method accepts args as structure of ListObjectsArgs, then get its address and init ListObjectsResult with pointer to it. Then this pointer used again for each request at ListObjectsRsult.Populate() to continue list next part of objects at minio storage bucket. But argument args in constructor ListObjects is not the original object, it is a copy of ListObjectsArgs created on function stack and pointer to this copy of object is transit to ListObjectsResult. Copy of object is destroyed on return from client.ListObjects. After that ListOjbectsResult in Populate() has freed pointer and when uses it this leads to segfault.
