When they are found to match, the common context lines in the preimage is replaced with the fixed copy, because these lines will then be copied to the corresponding place in the postimage by a later call to update_pre_post_images(). Lines that are added in the postimage, under --whitespace=fix, have their whitespace errors already fixed when apply_one_fragment() prepares the preimage and the postimage, so in the end, application of the patch can be done by replacing the block of text in the file being patched that matched the preimage with what is in the postimage that was updated by update_pre_post_images(). In the earlier days, fixing whitespace errors always resulted in reduction of size, either collapsing runs of spaces in the indent to a tab or removing the trailing whitespaces. These days, however, some whitespace error fix results in extending the size. 250b3c6c (apply --whitespace=fix: avoid running over the postimage buffer, 2013-03-22) tried to compute the final postimage size but its math was flawed. It counted the size of the block of text in the original being patched after fixing the whitespace errors on its lines that correspond to the preimage. That number does not have much to do with how big the final postimage would be. Instead count (1) the added lines in the postimage, whose size is the same as in the final patch result because their whitespace errors have already been corrected, and (2) the fixed size of the lines that are common.

| * apply: make update_pre_post_images() sanity check the given postlenJunio C Hamano2015-01-222-0/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "git apply --whitespace=fix" used to be able to assume that fixing errors will always reduce the size by e.g. stripping whitespaces at the end of lines or collapsing runs of spaces into tabs at the beginning of lines. An update to accomodate fixes that lengthens the result by e.g. expanding leading tabs into spaces were made long time ago but the logic miscounted the necessary space after such whitespace fixes, leading to either under-allocation or over-usage of already allocated space. Illustrate this with a runtime sanity-check to protect us from future breakage. The test was stolen from Kyle McKay who helped to identify the problem. Helped-by: "Kyle J.

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | The interactive "show a list and let the user choose from it" interface "add -i" used showed and prompted to the user even when the candidate list was empty, against which the only "choice" the user could have made was to choose nothing. * ak/add-i-empty-candidates: add -i: return from list_and_choose if there is no candidate

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The list_and_choose() helper is given a prompt and a list, asks the user to make selection from the list, and then returns a list of items chosen. Even when it is given an empty list as the original candidate set to choose from, it gave a prompt to the user, who can only say "I am done choosing". Return an empty result when the input is an empty list without bothering the user. The existing caller must already have a logic to say "Nothing to do" or an equivalent when the returned list is empty (i.e. the user chose to select nothing) if it is necessary, so no change to the callers is necessary. This fixes the case where "add untracked" is asked in "git add -i" and there is no untracked files in the working tree. We used to give an empty list of files to choose from with a prompt, but with this change, we no longer do.

These days, we try to use the full 40-hex object names internally to avoid ambiguity that can arise after rebase starts running. Newly created objects during the rebase may share the same prefix with existing commits listed in the insn sheet. These object names are shortened just before invoking the sequence editor to present the insn sheet to the end user, and then expanded back to full object names when the editor returns. But the code still used the shortened names when preparing the insn sheet for the very first time, resulting "7 hexdigits or more" output to the user. Change the code to use full 40-hex commit object names from the very beginning to make things more uniform. Signed-off-by: Kirill A.

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).

Otherwise the push is refused. This hook can be used to customize this "push-to-deploy" logic. The hook receives the commit with which the tip of the current branch is going to be updated, and can decide what kind of local changes are acceptable and how to update the index and the working tree to match the updated tip of the current branch. For example, the hook can simply run `git read-tree -u -m HEAD "$1"` in order to emulate 'git fetch' that is run in the reverse direction with `git push`, as the two-tree form of `read-tree -u -m` is essentially the same as `git checkout` that switches branches while keeping the local changes in the working tree that do not interfere with the difference between the branches.

Atomic pushes are activated by a new command line flag --atomic. In order to do this we also need to change the semantics for send_pack() slightly. The existing send_pack() function actually doesn't send all the refs back to the server when multiple refs are involved, for example when using --all. Several of the failure modes for pushes can already be detected locally in the send_pack client based on the information from the initial server side list of all the refs as generated by receive-pack. Any such refs that we thus know would fail to push are thus pruned from the list of refs we send to the server to update. For atomic pushes, we have to deal thus with both failures that are detected locally as well as failures that are reported back from the server. In order to do so we treat all local failures as push failures too. We introduce a new status code REF_STATUS_ATOMIC_PUSH_FAILED so we can flag all refs that we would normally have tried to push to the server but we did not due to local failures. This is to improve the error message back to the end user to flag that "these refs failed to update since the atomic push operation failed."

The default behavior is still the old non atomic way, one ref at a time. This is to cause as little disruption as possible to existing clients. It is unknown if there are client scripts that depend on the old non-atomic behavior so we make it opt-in for now. A later patch will add the possibility to actually use the functionality added by this patch. For now use_atomic is always 0.

To do so we need to stop receive-pack in case of the possible future bug when connectivity is not checked on a shallow push. Also while touching that code we considered that removing the reported refs may be harmful in some situations. Sound the message more like a "This Cannot Happen, Please Investigate!" instead of giving advice to remove refs.

| * | | | | | | | receive-pack.c: shorten the execute_commands loop over all commandsStefan Beller2015-01-071-16/+27

The new helper 'should_process_cmd' checks if a ref update is unnecessary, whether due to an error having occurred or for another reason. The helper 'warn_if_skipped_connectivity_check' warns if we have forgotten to run a connectivity check on a ref which is shallow for the client which would be a bug. This will help us to duplicate less code in a later patch when we make a second copy of the "execute_commands" loop. No functional change intended.
