Description Chen Chen 2016-12-01 03:13:38 UTC

Description of problem:
git-submodule is not available, so golang's "go get" always fails.
the submodule command has been alive since 2011. Couldn't believe it is not included in Fedora.

Version-Release number of selected component (if applicable):

How reproducible:
Always

Steps to Reproduce:
1. install git and golang
2. mkdir project
3. GOPATH=~/project go get -u github.com/golang/protobuf/proto

Actual results:
# cd /home/lunarshaddow/project/src/github.com/golang/protobuf; git submodule update --init --recursive
git: 'submodule' is not a git command. See 'git --help'.
package github.com/golang/protobuf/proto: exit status 1

Expected results:
Can install go package correctly.

Additional info:
I was trying to follow the tutorial at https://github.com/golang/protobuf.
Used golang 1.6.3_4.fc24 and protobuf-devel 2.6.1_4.fc24 to meet its dependency.

Can you list what git packages you have installed (the output from: rpm -qa git\*) ?  Perhaps you only have git-core and not git.

$ cat /etc/fedora-release
Fedora release 24 (Twenty Four)

$ rpm -qf /usr/libexec/git-core/git-submodule
git-2.7.4-3.fc24.x86_64

$ rpm -qa git\*
git-core-2.7.4-3.fc24.x86_64
git-2.7.4-3.fc24.x86_64
git-core-doc-2.7.4-3.fc24.x86_64

$ git submodule -h
usage: git submodule [--quiet] add [-b <branch>] [-f|--force] [--name <name>] [--reference <repository>] [--] <repository> [<path>]
   or: git submodule [--quiet] status [--cached] [--recursive] [--] [<path>...]
   or: git submodule [--quiet] init [--] [<path>...]

Comment 2 Chen Chen 2016-12-01 04:03:35 UTC

My fault. I only installed git-core.
Not sure why it didn't showed up in rpm provides.

I'm glad it was easy to resolve. :)

Since git-svn is a subpackage, it has a provides for the package name. This is what 'dnf provides git-svn' is finding.  There is no similar git-submodules subpackage, so the only provides which matches git-submodule is a file provides.

$ dnf provides '*/git-submodule'

(yash matches that provides search because it includes a completion file named git-submodule.)
