Return value of DavFile::get is -1 but no error is thrown

[mxxo]

Hello,

I would like to use DavFile::get to download some files. For the few cases I have tried it seems that DavFile::get returns -1 instead of the number of bytes read, but as far as I can tell, the read succeeds and no DavixError is thrown. I wanted to ask if I am indeed making an error here.

e.g.

#include <davix.hpp>
#include <iostream>
#include <vector>

int main() {
   Davix::Context c;
   Davix::RequestParams p;
   Davix::DavFile file(c, p, Davix::Uri("https://root.cern/files/LHCb002_data_v1.root"));

   std::vector<char> buf;
   auto ret = file.get(nullptr, buf);
   // file size is 11461 B
   if (buf.size() != 11461) {
      std::cout << "expected 11461 bytes read, got " << buf.size() << "\n";
   }
   std::cout << "got ret: " << ret << "\n";
   return 0;
}

prints

got ret: -1

Thank you very much for your time.

Hello,

I also had a look at the DavixFile::get(..) function and came up to the same problem as outlined in MergeRequest #70.

Many thanks for reporting and fixing this!

Cheers,
