Fetching from a shallow-cloned repository used to be forbidden, primarily because the codepaths involved were not carefully vetted and we did not bother supporting such usage.

Allow a safer "rewind of the remote tip" push than blind "--force", by requiring that the overwritten remote ref to be unchanged since the new history to replace it was prepared. The machinery is more or less ready. The "--force" option is again the big red button to override any safety, thanks to J6t's sanity (the original round allowed --lockref to defeat --force). The logic to choose the default implemented here is fragile (e.g. "git fetch" after seeing a failure will update the remote-tracking branch and will make the next "push" pass, defeating the safety pretty easily). It is suitable only for the simplest workflows, and it may hurt users more than it helps them. * jc/push-cas: push: teach --force-with-lease to smart-http transport send-pack: fix parsing of --force-with-lease option t5540/5541: smart-http does not support "--force-with-lease" t5533: test "push --force-with-lease" push --force-with-lease: tie it all together push --force-with-lease: implement logic to populate old_sha1_expect[] remote.c: add command line option parser for "--force-with-lease" builtin/push.c: use OPT_BOOL, not OPT_BOOLEAN cache.h: move remote/connect API out of it

Since 664059fb (transport-helper: update remote helper namespace, 2013-04-17), a 'push' operation on a remote helper updates the private ref by default.

2013-06-21transport-helper: be quiet on read errors from helpersLibravatar Jeff King1-1/+1
Prior to commit 81d340d4, we did not print any error message if a remote transport helper died unexpectedly. If a helper did not print any error message (e.g., because it crashed), the user could be left confused. That commit tried to rectify the situation by printing a note that the helper exited unexpectedly. However, this makes a much more common case worse: when a helper does die with a useful message, we print the extra "Reading from 'git-remote-foo failed" message. This can also end up confusing users, as they may not even know what remote helpers are (e.g., the fact that http support comes through git-remote-https is purely an implementation detail that most users do not know or care about). Since we do not have a good way of knowing whether the helper printed a useful error, and since the common failure mode is for it to do so, let's default to remaining quiet. Debuggers can dig further by setting GIT_TRANSPORT_HELPER_DEBUG. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

When pushing, the remote namespace is updated correctly (e.g. refs/origin/master), but not the remote helper's (e.g. refs/testgit/origin/master), which currently is only updated while fetching. Since the remote namespace is used to tell fast-export which commits to avoid (because they were already imported/exported), it makes sense to have them in sync so they don't get generated twice.

For the modes that need it. In the future we should probably error out, instead of providing half-assed support.

2013-04-15transport-helper: pass --signed-tags=warn-strip to fast-exportLibravatar John Keeping1-1/+2
Currently, attempting to push a signed tag to a remote helper which uses fast-export results in the remote helper failing because the default fast-export action for signed tags is "abort". This is not helpful for users because there is no way to pass additional arguments to fast-export here, either from the remote helper or from the command line. In general, the signature will be invalidated by whatever transformation a remote helper performs on a tag to push it to a repository in a different format so the correct behaviour is to strip the tag. Doing this silently may surprise people, so use "warn-strip" to issue a warning when a signed tag is encountered.

2013-04-11transport-helper: report errors properlyLibravatar Felipe Contreras1-1/+1
If a push fails because the remote-helper died (with fast-export), the user may not see any error message. We do correctly die with a failed exit code, as we notice that the helper has died while reading back the ref status from the helper. However, we don't print any message. This is OK if the helper itself printed a useful error message, but we cannot count on that; let's let the user know that the helper failed. In the long run, it may make more sense to propagate the error back up to push, so that it can present the usual status table and give a nicer message. But this is a much simpler fix that can help immediately. While we're adding tests, let's also confirm that the remote-helper dying is also detected when importing refs. We currently do so robustly when the helper uses the "done" feature (and that is what we test). We cannot do so reliably when the helper does not use the "done" feature, but it is not even worth testing; the right solution is for the helper to start using "done".

2013-01-24push: introduce REJECT_FETCH_FIRST and REJECT_NEEDS_FORCELibravatar Junio C Hamano1-0/+10
When we push to update an existing ref, if: * the object at the tip of the remote is not a commit; or * the object we are pushing is not a commit, it won't be correct to suggest to fetch, integrate and push again, as the old and new objects will not "merge". We should explain that the push must be forced when there is a non-committish object is involved in such a case. If we do not have the current object at the tip of the remote, we do not even know that object, when fetched, is something that can be merged. In such a case, suggesting to pull first just like non-fast-forward case may not be technically correct, but in practice, most such failures are seen when you try to push your work to a branch without knowing that somebody else already pushed to update the same branch since you forked, so "pull first" would work as a suggestion most of the time. And if the object at the tip is not a commit, "pull first" will fail, without making any permanent damage. As a side effect, it also makes the error message the user will get during the next "push" attempt easier to understand, now the user is aware that a non-commit object is involved. In these cases, the current code already rejects such a push on the client end, but we used the same error and advice messages as the ones used when rejecting a non-fast-forward push, i.e. pull from there and integrate before pushing again. Introduce new rejection reasons and reword the messages appropriately. [jc: with help by Peff on message details] Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-10-07Connect fast-import to the remote-helper via pipe, adding 'bidi-import' ↵Libravatar Florian Achleitner1-13/+31
capability The fast-import commands 'cat-blob' and 'ls' can be used by remote-helpers to retrieve information about blobs and trees that already exist in fast-import's memory. This requires a channel from fast-import to the remote-helper. remote-helpers that use these features shall advertise the new 'bidi-import' capability to signal that they require the communication channel. When forking fast-import in transport-helper.c connect it to a dup of the remote-helper's stdin-pipe. The additional file descriptor is passed to fast-import via its command line (--cat-blob-fd). It follows that git and fast-import are connected to the remote-helpers's stdin. Because git can send multiple commands to the remote-helper on it's stdin, it is required that helpers that advertise 'bidi-import' buffer all input commands until the batch of 'import' commands is ended by a newline before sending data to fast-import. This is to prevent mixing commands and fast-import responses on the helper's stdin.

2012-02-23disconnect from remote helpers more gentlyLibravatar Jeff King1-3/+10
When git spawns a remote helper program (like git-remote-http), the last thing we do before closing the pipe to the child process is to send a blank line, telling the helper that we are done issuing commands. However, the helper may already have exited, in which case the parent git process will receive SIGPIPE and die. In particular, this can happen with the remote-curl helper when it encounters errors during a push. The helper reports individual errors for each ref back to git-push, and then exits with a non-zero exit code. Depending on the exact timing of the write, the parent process may or may not receive SIGPIPE. This causes intermittent test failure in t5541.8, and is a side effect of 5238cbf (remote-curl: Fix push status report when all branches fail). Before that commit, remote-curl would not send the final blank line to indicate that the list of status lines was complete; it would just exit, closing the pipe. The parent git-push would notice the closed pipe while reading the status report and exit immediately itself, propagating the failing exit code. But post-5238cbf, remote-curl completes the status list before exiting, git-push actually runs to completion, and then it tries to cleanly disconnect the helper, leading to the SIGPIPE race above. This patch drops all error-checking when sending the final "we are about to hang up" blank line to helpers. There is nothing useful for the parent process to do about errors at that point anyway, and certainly failing to send our "we are done with commands" line to a helper that has already exited is not a problem.
