[Pkg-julia-devel] Bug#832798: src:libgit2: Please support https:// protocol by linking to OpenSSL

[Peter Colberg]

Package: src:libgit2
Version: 0.24.1-3
Severity: important

Dear Maintainer,

The 0.5.0 release of julia will use libgit2 to retrieve Julia package
repositories via https://. I have prepared a preliminary package [1],
which fails to clone a git repository [2]:

julia> Pkg.init()
INFO: Initializing package repository /home/peter/.julia/v0.5
INFO: Cloning METADATA from https://github.com/JuliaLang/METADATA.jl
ERROR: GitError(Code:ERROR, Class:Net, Failed to resolve address for https: Name or service not known)
 in init() at ./pkg/pkg.jl:70


julia upstream says [3] that libgit2 must be linked directly to a TLS
library in order to clone via https://, and that libcurl-gnutls is
used only for proxy support. I have rebuilt libgit2 with libssl-dev
using the attached patch, which enables julia to clone via https://.

Could you please provide a variant of libgit2 that is linked to
OpenSSL? To avoid multiple TLS libraries in the same program,
that variant should probably also link with libcurl4-openssl-dev.

(I marked this bug important since TLS is essential nowadays.)

Regards,
Peter
