We are planning to use git ls-remote <repository> [<refs>…] without any additional parameters concurrently to virtually any other Git operation. I'm looking for a confirmation that ls-remote is read-only, so it can't break any other operation.

Yes, it is a read-only operation.
Nothing in builtin/ls-remote.c suggests any operation modifying the local repo.
It sets as transport the TRANS_OPT_UPLOADPACK, which is used also in two other git commands (which don't modify the remote repo):
git clone(builtin/clone.c:919) andgit fetch(builtin/fetch.c:807)/* The program to use on the remote side to send a pack */ #define TRANS_OPT_UPLOADPACK "uploadpack"
It is asking the remote repo to send packs, nothing more.

Thanks, VonC. I can't see why `clone` or `fetch` would be read-only (they are obviously not!?). However, ls-remote.c actually looks extremely light-weight regarding the local repository. Seems like it only requires to read `.git/config` and that's all. – mstrap Mar 06 '14 at 14:33

@mstrap yes, I meant two other commands which don't modify the *remote* repo. – VonC Mar 06 '14 at 14:36
