• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description vowstar 2020-10-25 01:28:04 UTC]

After I install dev-vcs/git-2.29.1 in a clean environment, I tested the command:

git svn

but it failed with:

Can't locate SVN/Core.pm in @INC (you may need to install the SVN::Core module) (@INC contains: /usr/lib64/perl5/vendor_perl/5.30.3/x86_64-linux-thread-multi /usr/lib64/perl5/vendor_perl/5.30.3 /etc/perl /usr/local/lib64/perl5/5.30.3/x86_64-linux-thread-multi /usr/local/lib64/perl5/5.30.3 /usr/local/lib64/perl5 /usr/lib64/perl5/vendor_perl/5.30.2/x86_64-linux-thread-multi /usr/lib64/perl5/vendor_perl/5.30.2 /usr/lib64/perl5/vendor_perl/5.30.1 /usr/lib64/perl5/vendor_perl /usr/lib64/perl5/5.30.3/x86_64-linux-thread-multi /usr/lib64/perl5/5.30.3) at /usr/lib64/perl5/vendor_perl/5.30.3/Git/SVN/Utils.pm line 6.

After I installed dev-vcs/subversion, the problem disappeard.

Should git have some use flag to make dev-vcs/subversion as a depend?

Please post the output of

@vowstar:
2.29.1 was intended to remove git-svn support entirely; but now I need to know, do you need it back?

    dev-vcs/git: Re-added "subversion" USE flag.
    
    Upstream only killed svn-fe, not the svn perl module.

This news is too sad. It is bad news for some old projects that need mixed development of GIT and SVN for historical reasons. It is also a disaster for some popular EDA tools, such as virtouso of cadence (default SVN and no GIT).
