When we fetch from a remote, we do a revision walk to make sure that what we received is connected to our existing history. We do not do the same check for clone, which should be able to check that we received an intact history graph. The upside of this patch is that it will make clone more resilient against propagating repository corruption. The downside is that we will now traverse "rev-list --objects --all" down to the roots, which may take some time (it is especially noticeable for a "--local --bare" clone). Note that we need to adjust t5710, which tries to make such a bogus clone. Rather than checking after the fact that our clone is bogus, we can simplify it to just make sure "git clone" reports failure.

When clone is populating the working tree, it ignores the return status from unpack_trees; this means we may report a successful clone, even when the checkout fails. When checkout fails, we may want to leave the $GIT_DIR in place, as it might be possible to recover the data through further use of "git checkout" (e.g., if the checkout failed due to a transient error, disk full, etc). However, we already die on a number of other checkout-related errors, so this patch follows that pattern. In addition to marking a now-passing test, we need to adjust t5710, which blindly assumed it could make bogus clones of very deep alternates hierarchies. By using "--bare", we can avoid it actually touching any objects. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

We try not to let corruption pass unnoticed over fetches and clones. For the most part, this works, but there are some broken corner cases, including: 1. We do not detect missing objects over git-aware transports. This is a little hard to test, because the sending side will actually complain about the missing object. To fool it, we corrupt a repository such that we have a "misnamed" object: it claims to be sha1 X, but is really Y. This lets the sender blindly transmit it, but it is the receiver's responsibility to verify that what it got is sane (and it does not). 2. We do not detect missing or misnamed blobs during the checkout phase of clone. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

When we are streaming an index blob to disk, we store the error from stream_blob_to_fd in the "result" variable, and then immediately overwrite that with the return value of "close". That means we catch errors on close (e.g., problems committing the file to disk), but miss anything which happened before then. We can fix this by using bitwise-OR to accumulate errors in our result variable. While we're here, we can also simplify the error handling with an early return, which makes it easier to see under which circumstances we need to clean up.

We do not have many tests for handling corrupt objects. This new test at least checks that we detect a byte error in a corrupt blob object while streaming it out with cat-file. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

The read_istream_loose function loops on inflating a chunk of data from an mmap'd loose object. We end the loop when we run out of space in our output buffer, or if we see a zlib error. We need to treat Z_BUF_ERROR specially, though, as it is not fatal; it is just zlib's way of telling us that we need to either feed it more input or give it more output space. It is perfectly normal for us to hit this when we are at the end of our buffer. However, we may also get Z_BUF_ERROR because we have run out of input. In a well-formed object, this should not happen, because we have fed the whole mmap'd contents to zlib. But if the object is truncated or corrupt, we will loop forever, never giving zlib any more data, but continuing to ask it to inflate. We can fix this by considering it an error when zlib returns Z_BUF_ERROR but we still have output space left (which means it must want more input, which we know is a truncation error). It would not be sufficient to just check whether zlib had consumed all the input at the start of the loop, as it might still want to generate output from what is in its internal state.

The filter istream pulls data from an "upstream" stream, running it through a filter function. However, we did not properly notice when the upstream filter yielded an error, and just returned what we had read. Instead, we should propagate the error.

It's possible for read_istream to return an error, in which case we just end up in an infinite loop (aside from EOF, we do not even look at the result, but just feed it straight into our running hash). Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

We call read_istream, but never check its return value for errors. This can lead to us looping infinitely, as we just keep trying to write "-1" bytes (and we do not notice the error, as we simply check that write_in_full reports the same number of bytes we fed it, which of course is also -1).

The "--match=<pattern>" option of "git describe", when used with "--all" to allow refs that are not annotated tags to be used as a base of description, did not restrict the output from the command to those that match the given pattern.
