"chown" is typo'd as "chowm". To be useful, the contribution might also include instructions on how it should be used with git, and perhaps also reasoning for why someone would want to use it in place of etckeeper, metastore, setgitperms, etc. j. ``` ## Jay Soffian, 2009-01-09 00:28 Subject: Re: git-cache-meta -- simple file meta data caching and applying Message-ID: <76718490901081628x62da43bcia5cdbb160b0ff24a@mail.gmail.com> URL: https://gitlist.dev/e/76718490901081628x62da43bcia5cdbb160b0ff24a%40mail.gmail.com In-Reply-To: <76718490901081622q618c43d0t333882cbe44f6b30@mail.gmail.com> ``` On Thu, Jan 8, 2009 at 7:22 PM, Jay Soffian wrote: > It doesn't handle paths which contain white-space.

Also, might be worth mentioning it requires GNU find. j. ``` ## jidanni@jidanni.org, 2009-01-09 02:50 Subject: Re: git-cache-meta -- simple file meta data caching and applying Message-ID: <878wpljiq9.fsf@jidanni.org> URL: https://gitlist.dev/e/878wpljiq9.fsf%40jidanni.org In-Reply-To: <76718490901081628x62da43bcia5cdbb160b0ff24a@mail.gmail.com> ``` Fixed. Manly the program aims to be tiny. Perhaps I should include a full example of using it with git-bundle. #!/bin/sh -e #git-cache-meta -- file meta data caching for possible use with #git-bundle, git-fast-export, git-archive, hooks, as a simple #alternative to etckeeper, metastore, setgitperms.

It's specifically designed to be able to generate the .orig.tar.gz that Debian packages are based on from a VCS checkout, but it's code might be useful. I do like your script though. It's simple and the output is plain text so it is easy to have your VCS maintain it. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/ ``` ## jidanni@jidanni.org, 2009-01-10 17:43 Subject: [PATCH] git-cache-meta -- file owner and permissions caching, minimalist approach Message-ID: <87eizb12gu.fsf_-_@jidanni.org> URL: https://gitlist.dev/e/87eizb12gu.fsf_-_%40jidanni.org In-Reply-To: <200901082229.46433.bss@iguanasuicide.net> ``` Signed-off-by: jidanni --- contrib/metadata/git-cache-meta | 19 +++++++++++++++++++ 1 files changed, 19 insertions(+), 0 deletions(-) create mode 100755 contrib/metadata/git-cache-meta diff --git a/contrib/metadata/git-cache-meta b/contrib/metadata/git-cache-meta new file mode 100755 index 0000000..5e1b740 --- /dev/null +++ b/contrib/metadata/git-cache-meta @@ -0,0 +1,19 @@ +#!/bin/sh -e +# git-cache-meta -- file owner and permissions caching, minimalist approach +: ${GIT_CACHE_META_FILE=.git_cache_meta} #simpler not to git-add it +case $@ in + --store|--stdout) + case $1 in --store) exec > $GIT_CACHE_META_FILE; esac + git ls-files|xargs -I{} find {} \ + \( -user ${USER?} -o -printf "chown %u '%p'\n" \) \ + \( -group $USER -o -printf "chgrp %g '%p'\n" \) \ + \( \( -type l -o -perm 755 -o -perm 644 \) \ + -o -printf "chmod %#m '%p'\n" \);;#requires GNU Find + --apply) sh -e $GIT_CACHE_META_FILE;; + *) 1>&2 cat <
