We can use xsnprintf to do our truncation check with less code. The error message isn't as specific, but the point is that this isn't supposed to trigger in the first place (because our buffer is big enough to handle any int). Signed-off-by: Jeff King <peff@peff.net>

"git ls-remote" and "git archive --remote" are designed to work without being in a directory under Git's control. However, recent updates revealed that we randomly look into a directory called .git/ without actually doing necessary set-up when working in a repository. Stop doing so. * jn/remote-helpers-with-git-dir: remote helpers: avoid blind fall-back to ".git" when setting GIT_DIR remote: avoid reading $GIT_DIR config in non-repo
2017-02-14remote helpers: avoid blind fall-back to ".git" when setting GIT_DIRJonathan Nieder
To push from or fetch to the current repository, remote helpers need to know what repository that is. Accordingly, Git sets the GIT_DIR environment variable to the path to the current repository when invoking remote helpers. There is a special case it does not handle: "git ls-remote" and "git archive --remote" can be run to inspect a remote repository without being run from any local repository. GIT_DIR is not useful in this scenario: - if we are not in a repository, we don't need to set GIT_DIR to override an existing GIT_DIR value from the environment. If GIT_DIR is present then we would be in a repository if it were valid and would have called die() if it weren't. - not setting GIT_DIR may cause a helper to do the usual discovery walk to find the repository. But we know we're not in one, or we would have found it ourselves. So in the worst case it may expend a little extra effort to try to find a repository and fail (for example, remote-curl would do this to try to find repository-level configuration). So leave GIT_DIR unset in this case. This makes GIT_DIR easier to understand for remote helper authors and makes transport code less of a special case for repository discovery.

2017-02-08push options: pass push options to the transport helperStefan Beller
When using non-builtin protocols relying on a transport helper (such as http), push options are not propagated to the helper. The user could ask for push options and a push would seemingly succeed, but the push options would never be transported to the server, misleading the users expectation. Fix this by propagating the push options to the transport helper. This is only addressing the first issue of (1) the helper protocol does not propagate push-option (2) the http helper is not prepared to handle push-option Once we fix (2), the http transport helper can make use of push options as well, but that happens as a follow up. (1) is a bug fix, whereas (2) is a feature, which is why we only do (1) here. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-06-13fetch, upload-pack: --deepen=N extends shallow boundary by N commitsNguyễn Thái Ngọc Duy
In git-fetch, --depth argument is always relative with the latest remote refs. This makes it a bit difficult to cover this use case, where the user wants to make the shallow history, say 3 levels deeper. It would work if remote refs have not moved yet, but nobody can guarantee that, especially when that use case is performed a couple months after the last clone or "git fetch --depth". Also, modifying shallow boundary using --depth does not work well with clones created by --since or --not. This patch fixes that. A new argument --deepen=<N> will add <N> more (*) parent commits to the current history regardless of where remote refs are. Have/Want negotiation is still respected. So if remote refs move, the server will send two chunks: one between "have" and "want" and another to extend shallow history. In theory, the client could send no "want"s in order to get the second chunk only. But the protocol does not allow that. Either you send no want lines, which means ls-remote; or you have to send at least one want line that carries deep-relative to the server.. The main work was done by Dongcan Jiang. I fixed it up here and there. And of course all the bugs belong to me. (*) We could even support --deepen=<N> where <N> is negative. In that case we can cut some history from the shallow clone. This operation (and --depth=<shorter depth>) does not require interaction with remote side (and more complicated to implement as a result).

2016-01-15strbuf: introduce strbuf_getline_{lf,nul}()Junio C Hamano
The strbuf_getline() interface allows a byte other than LF or NUL as the line terminator, but this is only because I wrote these codepaths anticipating that there might be a value other than NUL and LF that could be useful when I introduced line_termination long time ago. No useful caller that uses other value has emerged. By now, it is clear that the interface is overly broad without a good reason. Many codepaths have hardcoded preference to read either LF terminated or NUL terminated records from their input, and then call strbuf_getline() with LF or NUL as the third parameter. This step introduces two thin wrappers around strbuf_getline(), namely, strbuf_getline_lf() and strbuf_getline_nul(), and mechanically rewrites these call sites to call either one of them. The changes contained in this patch are: * introduction of these two functions in strbuf.[ch] * mechanical conversion of all callers to strbuf_getline() with either '\n' or '\0' as the third parameter to instead call the respective thin wrapper. After this step, output from "git grep 'strbuf_getline('" would become a lot smaller. An interim goal of this series is to make this an empty set, so that we can have strbuf_getline_crlf() take over the shorter name strbuf_getline(). Signed-off-by: Junio C Hamano <gitster@pobox.com>

2015-09-23transport: add a protocol-whitelist environment variableJeff King
If we are cloning an untrusted remote repository into a sandbox, we may also want to fetch remote submodules in order to get the complete view as intended by the other side. However, that opens us up to attacks where a malicious user gets us to clone something they would not otherwise have access to (this is not necessarily a problem by itself, but we may then act on the cloned contents in a way that exposes them to the attacker). Ideally such a setup would sandbox git entirely away from high-value items, but this is not always practical or easy to set up (e.g., OS network controls may block multiple protocols, and we would want to enable some but not others). We can help this case by providing a way to restrict particular protocols. We use a whitelist in the environment. This is more annoying to set up than a blacklist, but defaults to safety if the set of protocols git supports grows). If no whitelist is specified, we continue to default to allowing all protocols (this is an "unsafe" default, but since the minority of users will want this sandboxing effect, it is the only sensible one). A note on the tests: ideally these would all be in a single test file, but the git-daemon and httpd test infrastructure is an all-or-nothing proposition rather than a test-by-test prerequisite. By putting them all together, we would be unable to test the file-local code on machines without apache. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2015-01-22transport-helper: do not request symbolic refs to remote helpersMike Hommey
A typical remote helper will return a `list` of refs containing a symbolic ref HEAD, pointing to, e.g. refs/heads/master. In the case of a clone, all the refs are being requested through `fetch` or `import`, including the symbolic ref. While this works properly, in some cases of a fetch, like `git fetch url` or `git fetch origin HEAD`, or any fetch command involving a symbolic ref without also fetching the corresponding ref it points to, the fetch command fails with: fatal: bad object 0000000000000000000000000000000000000000 error: <remote> did not send all necessary objects (in the case the remote helper returned '?' values to the `list` command). This is because there is only one ref given to fetch(), and it's not further resolved to something at the end of fetch_with_import(). While this can be somehow handled in the remote helper itself, by adding a refspec for the symbolic ref, and storing an explicit ref in a private namespace, and then handling the `import` for that symbolic ref specifically, very few existing remote helpers are actually doing that. So, instead of requesting the exact list of wanted refs to remote helpers, treat symbolic refs differently and request the ref they point to instead. Then, resolve the symbolic refs values based on the pointed ref. This assumes there is no more than one level of indirection (a symbolic ref doesn't point to another symbolic ref).

2014-09-17signed push: teach smart-HTTP to pass "git push --signed" aroundJunio C Hamano
The "--signed" option received by "git push" is first passed to the transport layer, which the native transport directly uses to notice that a push certificate needs to be sent. When the transport-helper is involved, however, the option needs to be told to the helper with set_helper_option(), and the helper needs to take necessary action. For the smart-HTTP helper, the "necessary action" involves spawning the "git send-pack" subprocess with the "--signed" option. Once the above all gets wired in, the smart-HTTP transport now can use the push certificate mechanism to authenticate its pushes. Add a test that is modeled after tests for the native transport in t5534-push-signed.sh to t5541-http-push-smart.sh. Update the test Apache configuration to pass GNUPGHOME environment variable through. As PassEnv would trigger warnings for an environment variable that is not set, export it from test-lib.sh set to a harmless value when GnuPG is not being used in the tests. Note that the added test is deliberately loose and does not check the nonce in this step. This is because the stateless RPC mode is inevitably flaky and a nonce that comes back in the actual push processing is one issued by a different process; if the two interactions with the server crossed a second boundary, the nonces will not match and such a check will fail. A later patch in the series will work around this shortcoming. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-06-20transport-helper: avoid reading past end-of-stringJeff King
We detect the "import-marks" capability by looking for that string, but _without_ a trailing space. Then we skip past it using strlen("import-marks "), with a space. So if a remote helper gives us exactly "import-marks", we will read past the end-of-string by one character. This is unlikely to be a problem in practice, because such input is malformed in the first place, and because there is a good chance that the string has an extra NUL terminator one character after the original (because it formerly had a newline in it that we parsed off). We can fix it by using skip_prefix with "import-marks ", with the space. The other form appears to be a typo from a515ebe (transport-helper: implement marks location as capability, 2011-07-16); "import-marks" has never existed without an argument, and it should match the "export-marks" definition above. Speaking of which, we can also use skip_prefix in a few other places while we are in the function. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-05-27transport-helper.c: rearrange xcalloc argumentsBrian Gesiak
xcalloc() takes two arguments: the number of elements and their size. transport_helper_init passes the arguments in reverse order, passing the size of a helper_data*, followed by the number to allocate. Rearrange them so they are in the correct order. Signed-off-by: Brian Gesiak <modocache@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-05-20Revert "Merge branch 'jc/graduate-remote-hg-bzr' (early part)"Junio C Hamano
Instead of showing a warning and working as before, fail and show the message and force immediate upgrade from their upstream repositories when these tools are run, per request from their primary author. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-05-20Revert "Merge branch 'fc/transport-helper-sync-error-fix'"Junio C Hamano
This reverts commit d508e4a8e2391ae2596403b6478d01cf3d5f928f, reversing changes made to e42552135a2a396f37053a89f44952ea907870b2. The author of the original topic says he broke the upcoming 2.0 release with something that relates to "synchronization crash regression" while refusing to give further specifics, so this would unfortunately be the safest option for the upcoming release.
