[savannah-help-public] [sr #108761] Please allow Non-Fast-Forward commits for GNU ccd2cue's Git repository

[Assaf Gordon]

Follow-up Comment #4, sr #108761 (project administration):

Hello Bruno,

I've experimented with several cvs conversion tools, and for me,
cvs-fast-export failed the least :)

If you do end up writing the article, I'd be happy to add it to the Savannah
Wiki.

If it helps in any way to your article, this is how I'd convert the CVS
repository:


====

## Download, Install CVS-FAST-EXPORT
$ wget http://www.catb.org/~esr/cvs-fast-export/cvs-fast-export-1.29.tar.gz
$ tar -xf cvs-fast-export-1.29.tar.gz
$ cd cvs-fast-export-1.29
$ make
$ sudo make install

## Get CVS repostiory from Savannah
$ rsync -r rsync://cvs.savannah.gnu.org/sources/ccd2cue .
$ ls ccd2cue/
ccd2cue  CVSROOT

## Find author IDs in CVS logs
$ find ccd2cue -type f | cvs-fast-export -a
oitofelix

## Manually prepare author-map file, one entry for each author
$ printf "oitofelix=Bruno Félix Rezende Ribeiro <address@hidden>\n" >
author-map.txt

## Convert CVS to git-fast-import file
$ find ccd2cue -type f | cvs-fast-export -A author-map.txt >
ccd2cue.git-fast-import

## Prepare empty GIT repository
$ git init --bare ccd2cue.git
Initialized empty Git repository in
/home/gordon/sources/cvs-convert/ccd2cue.git/
$ cd ccd2cue.git

## Run Git-Fast-Import
$ git fast-import < ../ccd2cue.git-fast-import
