我可以使用svnsync創建淺倉庫副本嗎？

Question

有一個在線回購有13k提交，但我只對其中的最後1000個感興趣。是否有可能使用svnsync複製它們？

我希望能夠從這個本地資源庫最後提交1000內結賬，並且它應該不是從服務器

版本號必須保留更快。
svnsync必須能夠將未來修訂通常同步到本地存儲庫中。

在以下示例中，我保存了回購的最後45個提交。助手python腳本如下。

# svnsync 1.6.11 
# rhel 6 x86_64 

# params 
svn_baserepourl="http://svn.igniterealtime.org/svn/repos" 
svn_subdir="spark/trunk" 
reponame=spark 
skipuntil=13774 


# well-known svnsync preparation 
repopath=`pwd`/$reponame.svn 
svnadmin create "$repopath" 

echo '#!/bin/sh' >"$repopath"/hooks/pre-revprop-change 
chmod +x "$repopath"/hooks/pre-revprop-change 

svnsync init file://"$repopath" "$svn_baserepourl/$svn_subdir" 

expectedfmt="4 
layout sharded 1000" 

if [ x"$expectedfmt" != x"$(cat "$repopath/db/format")" ]; then 
    echo unknown db format 
fi 

# create database folder structure 
(cd "$repopath/db" && echo $(for ((i=0; i<=$((skipuntil/1000)) ; i++)) ; do mkdir -p revprops/$i revs/$i; done)) 

# don't create last skipped revision 
skipuntil=$((skipuntil - 1)) 

# create dummy revision files 
(cd "$repopath/db" && for ((i=0; i<=$skipuntil; i++)) ; do echo revprops/$((i/1000))/$i; echo revs/$((i/1000))/$i; done | xargs touch) 

# update revision counter 
echo $skipuntil >"$repopath/db/current" 

# we need a valid revision file 
cp "$repopath/db/revs/0/0" "$repopath/db/revs/$((skipuntil/1000))/$skipuntil" 

# last skipped revision number 
skipuntil=$((skipuntil + 1)) 

if false; then 
    # TODO: if svnrdump available 
    # mkdir in local repo 
    # svnrdump last skipped revision and subdir 
    # svnadmin load --parent-dir subdir 
    : 
else 
    # checkout last skipped revision 
    rm -rf temptree 
    svn co -r $skipuntil "$svn_baserepourl/$svn_subdir" "temptree/$svn_subdir" 
    cd temptree 
    pushd "$svn_subdir" 

    # save properties 
    svn proplist --xml -v -R | ~/svnprops.py >/tmp/propset.sh 

    # remove .svn folders 
    find . -name .svn -print0 | xargs -0 rm -rf 

    popd 

    # checkout our copy 
    svn co "file://$repopath" . 

    # add the files 
    svn add --no-ignore --force . 

    # delete automatic props 
    for p in $(svn proplist -q -R | sort -u); do svn propdel -q -R $p; done 

    # restore original props 
    pushd "$svn_subdir" 
    sh /tmp/propset.sh 
    popd 

    # commit the last skipped revision 
    svn commit -m"shallow root" 

    cd .. 
    rm -rf temptree 
fi 

# update svnsync counters 
svn propset --revprop -r 0 svn:sync-last-merged-rev $skipuntil "file://$repopath" 
svn propset --revprop -r 0 svn:sync-currently-copying $((skipuntil+1)) "file://$repopath" 

# sync! 
svnsync sync "file://$repopath" 

這是一些老svnprops.py回購之間的svn屬性複製：

將這些最新的1000個修訂版複製到哪裏？ svnsync工具用於存儲庫複製，而不是「複製」修訂版。如果您想遠程獲取最近的1000個修訂版本，請使用​​，您可以在其中指定版本範圍。
