The script to use is smedev/git-cvs2git.sh

  1. $1 = Module name e.g. smeserver-ddclient
  2. $2 = Organisation (smeserver or smecontrib)e
  3. optional (can be in any order)
  4. <local> will use parameters set for local repository else it will use remote
  5. <debug> turn on debug regardless of ~/.smegit/config
  6. <noisy> print a line showing how it was called

This will take a CVS package and create a equivalent git repo and copy across the data.

See also: https://wiki.koozali.org/Howto_create_a_gitea_repo_and_build_an_rpm#Creating_the_Repo_on_the_gitea_Server

DEPRECATED:

Issues:

  1. How to partition the repos between smecontribs and core? different User? - smecontribs and smeserver directories? Then module name.With contribs10 / sme10 directories underneath, and also the common directory.
  2. Need ssh access to gitea for automatic creation of repos, else each one has to be created by hand!
  3. Realising that I need the contribs10/11/12 directories under the module name if I am going to get make mockbuild to work.
  4. Are going to hold the rpm's in the git repo as well? Otherwise we need the .gitignore set to *.rpm
  5. I presume we will hold the file tree tar file in git?
  6. I also presume that we will have one git repo per module? Rather than share Importing the a repo across all modules?


Bringing across all the CVS history as well...

According to google, git has a parameter "cvsimport" since version 2.1, however the version in my Rocky 8 system is 2.3.1, but has not such parameter. Latest comments I can find are for 2012, and some say it is not very reliable, so I suspect it has been withdrawn.

Only tool I can find is "cvs-fast-import" which will work with git-fast-import to import all the CVS data (inc history)

No rpms seem to exist, so I am having to build it on the Rocky 8 system (on which I also have CVS installed, and have access to the SME CVS)

Code for cvs-fast-import is here : https://gitlab.com/esr/cvs-fast-export

I needed 

git clone https://gitlab.com/esr/cvs-fast-export
cd cvs-fast-export
sudo dnf install dnf-plgins-core
sudo dnf install epel-release
sudo dnf config-manager --set-enabled powertools
sudo buildprep --doc
make install-bin
make install

[brianr@rockysmebuild cvs-fast-export]$ cvs-fast-export --help

Example: find | cvs-fast-export
[brianr@rockysmebuild cvs-fast-export]$

It includes a "cvsconvert" script which runs cvs-fast-convert and writes to a git repo.

HOWEVER it needs access to the CVS files, not just the cvs client!

[brianr@rockysmebuild cvs-fast-export]$ more cvsconvert 
#!/usr/bin/env python3
"""
cvsconvert - convert a CVS repo and check against the original

Convert, and check the tree content of a gitspace conversion against
the CVS.  The tip state of every branch, and every tag, is checked.

Will produce spurious errors if any CVS branch name had to be sanitized.

cvssync (part of the cvs package) is the way to go.

See here: https://stackoverflow.com/questions/28693868/migration-from-cvs-to-git


This worked:

cvssync brianr@shell.koozali.org:/cvs/smecontribs/rpms smeserver-ddclient

it creates a directory "smeserver-ddclient" of the CVS files.

and "find . | cvs-fast-export | git fast-import" also did something, although I am not sure it was quite what I expected!!
