To create that new repository, I rewrote the git repository from et.redhat.com to correct a few minor problems. In case anyone is interested, here are the details. --------------------------------------- Some commits had incomplete names. Run this to see all 64 commits: $ git log --pretty=format:%h:%an|grep -v ' ' Here's a summary: $ git log --pretty=format:%an|grep -v ' '|sort|uniq -c 1 aliguori 13 clalance 3 crobinso 8 danms 5 dlesko 23 meyering 11 sakaia ============================ Note that rewriting changes nearly all SHA1 values, so any reference to an SHA1 in a commit log should be updated to point to the new SHA1. There are a few: $ git log|grep -E '\b[0-9a-f]{7,40}\b'|grep -v '^commit' This regressed via commit 4c3f3b4d. [043d702f] "use virAsprintf instead of asprintf" introducted The 'getVer' fix introducted in d88d459d [Allow remote://hostname/ Bug introduced in 895d0fdf5bef358fafb91c672609190b3088097b. ==================================================== Run the following long(!) command to rewrite the "master" branch, preserving tags (but not signed ones), fixing bogus author names and preserving SHA1 references like the above: git filter-branch -d $TMPDIR/.git-rewrite \ --tag-name-filter cat \ --env-filter ' case $GIT_AUTHOR_NAME in agx) n="Guido Günther" e="a...@sigxcpu.org" ;; aliguori) n="Anthony Liguori" e="aligu...@us.ibm.com" ;; clalance) n="Chris Lalancette" e="clala...@redhat.com" ;; crobinso) n="Cole Robinson" e="crobi...@redhat.com" ;; danms) n="Dan Smith" e="da...@us.ibm.com" ;; dlesko) n="David L.

Reapply the signed vM.N.O tags: for i in $(git tag -l 'LIBVIRT_*'); do v=$(echo $i|sed 's/LIBVIRT_/v/;s/_/./g') echo $v git tag -f -s -m$v $v $i done ==================================================== With the above changes, we've bloated the repository by ~50%, increasing its size from 22M to 34M. Remove the cruft: git for-each-ref --format="%(refname)" refs/original/ \ | xargs -n 1 git update-ref -d git reflog expire --expire=now --all git gc --prune=now And that brings it back down to 23M. Run this function git-repo-compress() { local d=$1 du -sh "$d"; start=$(date); /usr/bin/time \ git --git-dir=$d repack -afd --window=250 --depth=250 echo started $start; date; du -sh "$d" } to compress a few remaining bits. Final size: 21M. Push to libvirt.org: git push libvirt.org:/git/libvirt.git master:master git push --tags libvirt.org:/git/libvirt.git ==================================================== After I'd pushed all of the above, Dan Berrange noticed that the new signed tags were out of order and had all been created today. Back-date the signed tags so that each has the same date as its unsigned counterpart: for i in $(git tag -l 'LIBVIRT_*'); do v=$(echo $i|sed 's/LIBVIRT_/v/;s/_/./g') date=$(git log --pretty=%ci -1 $i) echo $v GIT_COMMITTER_DATE="$date" git tag -f -s -m$v $v $i done # And push (now we need the -f option): git push -f --tags libvirt.org:/git/libvirt.git -- Libvir-list mailing list Libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
