build status

Davix aims to make the task of managing files over HTTP-based protocols simple. It is being developed by IT-ST at CERN, and while the project's purpose is its use on the CERN grid, the functionality offered is generic.

HTTP File Management

HTTP is gaining popularity for file management tasks, beyond its traditional use for serving web pages. It is versatile enough to be fit for this purpose; PUT, MOVE and DELETE requests can be used for basic file manipulation, for example. (uploading, moving, and deleting a file, respectively)

Some common file-management operations are not possible to do with plain HTTP, however, which is why the WebDAV extensions were developed, which davix supports.

Davix also supports a plethora of authentication methods:

  • x509 user certificate
  • VOMS proxy
  • RFC proxy with VOMS extensions support
  • username / password
  • AWS S3 compatible services
  • Microsoft Azure compatible services


Davix provides a shared library as well as a few command line tools. The library offers two sets of APIs, a file-oriented and a POSIX-like interface.

Here are some example invocations of the command-line tools.

# upload a file using a VOMS proxy
davix-put myfile https://someserver/dir/myfile -E /tmp/x509up_u1000
# download a file from an Amazon S3 bucket
davix-get https://mybucket.s3.amazonaws.com/somefile --s3accesskey [..] --s3secretkey [..]
# do an ls on a WebDAV-enabled server
davix-ls https://someserver/dir


  1. Install the necessary dependencies:

    • cmake
    • libxml2-devel
    • openssl-devel
  2. Compile:

git clone https://github.com/cern-fts/davix.git
cd davix
git submodule update --recursive --init
mkdir build && cd build
cmake ..

You can now try running an example command:

./src/tools/davix-get https://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.0.1

Release tarballs

To generate a blessed release tarball, run packaging/make-dist.sh from the root of this git repository. The tarball will appear under ./build, and will correspond to whichever git commit or tag you're currently on.


The official repository is the one on GitHub. It's automatically mirrored on CERN Gitlab for CI purposes. This means:

  • Use GitHub for new commits, issues, or pull requests.
  • Please don't commit directly on GitLab.
  • After a commit, GitLab will mirror the changes automatically, and run CI. Treat Gitlab as if it were ie a Jenkins CI instance.


Suggestions and patches are more than welcome. You can send an email to the davix-devel CERN mailing list, or contact directly the current maintainer.
