In commitee27ca4, we started restricting remote git-archive invocations to only accessing reachable commits. This matches what upload-pack allows, but does restrict some useful cases (e.g., HEAD:foo). We loosened this in0f544ee, which allows `foo:bar` as long as `foo` is a ref tip. However, that still doesn't allow many useful things, like: 1. Commits accessible from a ref, like `foo^:bar`, which are reachable 2. Arbitrary sha1s, even if they are reachable. We can do a full object-reachability check for these cases, but it can be quite expensive if the client has sent us the sha1 of a tree; we have to visit every sub-tree of every commit in the worst case. Let's instead give site admins an escape hatch, in case they prefer the more liberal behavior. For many sites, the full object database is public anyway (e.g., if you allow dumb walker access), or the site admin may simply decide the security/convenience tradeoff is not worth it. This patch adds a new config option to disable the restrictions added inee27ca4. It defaults to off, meaning there is no change in behavior by default.

test_description='git archive and git get-tar-commit-id test
|
|
|
|
This test covers the topics of file contents, commit date handling and
|
|
commit id embedding:
|
|
|
|
The contents of the repository is compared to the extracted tar
|
|
archive. The repository contains simple text files, symlinks and a
|
|
binary file (/bin/sh). Only paths shorter than 99 characters are
|
|
used.
|
|
|
|
git archive applies the commit date to every file in the archive it
|
|
creates. The test sets the commit date to a specific value and checks
|
|
if the tar archive contains that value.
|
|
|
|
When giving git archive a commit id (in contrast to a tree id) it
|
|
embeds this commit id into the tar archive as a comment. The test
|
|
checks the ability of git get-tar-commit-id to figure it out from the
|
|
tar file.
