|\ | | | | | | | | | | | | | | | | | | | | | | | | Improve error and advice messages given locally when "git push" refuses when it cannot compute fast-forwardness by separating these cases from the normal "not a fast-forward; merge first and push again" case. * jc/push-reject-reasons: push: finishing touches to explain REJECT_ALREADY_EXISTS better push: introduce REJECT_FETCH_FIRST and REJECT_NEEDS_FORCE push: further simplify the logic to assign rejection reason push: further clean up fields of "struct ref"
| * push: introduce REJECT_FETCH_FIRST and REJECT_NEEDS_FORCEJunio C Hamano2013-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * push: further clean up fields of "struct ref"Junio C Hamano2013-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "nonfastforward" and "update" fields are only used while deciding what value to assign to the "status" locally in a single function. Remove them from the "struct ref". The "requires_force" field is not used to decide if the proposed update requires a --force option to succeed, or to record such a decision made elsewhere. It is used by status reporting code that the particular update was "forced". Rename it to "forced_update", and move the code to assign to it around to further clarify how it is used and what it is used for. Signed-off-by: Junio C Hamano <gitster@pobox.com>

For matching keys without subsections, it is simple enough to call "strcmp". Matching keys with subsections is a little more complicated, and each callback does it in an ad-hoc way, usually involving error-prone pointer arithmetic. Let's provide a helper that keeps the pointer arithmetic all in one place.

|\ \ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some reimplementations of Git does not write all the stat info back to the index due to their implementation limitations (e.g. jgit running on Java). A configuration option can tell Git to ignore changes to most of the stat fields and only pay attention to mtime and size, which these implementations can reliably update. This avoids excessive revalidation of contents. * rr/minimal-stat: Enable minimal stat checking

Other implementations, eg. Git in cygwin are allegedly also somewhat incompatible with Git For Windows and on *nix platforms the resolution of the timestamps may differ. Any stat checking by git will then need to check content, which may be very slow, particularly on Windows. Since mtime and size is typically enough we should allow the user to tell git to avoid checking these fields if they are set to zero in the index. This change introduces a core.checkstat config option where the the user can select to check all fields (default), or just size and the whole second part of mtime (minimal).

We limit the use of these macros to __GNUC__, since gcc is the primary beneficiary of the new information, and because we use GNU features for handling variadic macros. However, clang also defines __GNUC__, but generates warnings with -Wunused-value when these macros are used in a void context, because the constant "-1" ends up being useless. Gcc does not complain about this case (though it is unclear if it is because it is smart enough to see what we are doing, or too dumb to realize that the -1 is unused). We can squelch the warning by just disabling these macros when clang is in use.

The primary cause of the bug is that the check in a new helper function is_forwardable() assumed both old and new objects are available and can be checked, which is not always the case. The way the caller uses the result of this function is also wrong. If the helper says "we do not want to let this push go through", the caller unconditionally translates it into "we blocked it because the destination already exists", which is not true at all in this case. Fix this by doing these three things: * Remove unnecessary not_forwardable from "struct ref"; it is only used inside set_ref_status_for_push(); * Make "refs/tags/" the only hierarchy that cannot be replaced without --force; * Remove the misguided attempt to force that everything that updates an existing ref has to be a commit outside "refs/tags/" hierarchy. The policy last one tried to implement may later be resurrected and extended to ensure fast-forwardness (defined as "not losing objects", extending from the traditional "not losing commits from the resulting history") when objects that are not commit are involved (e.g. an annotated tag in hierarchies outside refs/tags), but such a logic belongs to "is this a fast-forward?" check that is done by ref_newer(); is_forwardable(), which is now removed, was not the right place to do so.

These pathspecs are treated not as literal paths, but as glob patterns that can be fed to fnmatch. When a user is giving a specific pattern, this is a nice feature. However, when programatically providing pathspecs, it can be a nuisance. For example, to find the latest revision which modified "$foo", one can use "git rev-list -- $foo". But if "$foo" contains glob characters (e.g., "f*"), it will erroneously match more entries than desired. The caller needs to quote the characters in $foo, and even then, the results may not be exactly the same as with a literal pathspec. For instance, the depth checks in match_pathspec_depth do not kick in if we match via fnmatch. This patch introduces a global command-line option (i.e., one for "git" itself, not for specific commands) to turn this behavior off. It also has a matching environment variable, which can make it easier if you are a script or porcelain interface that is going to issue many such commands. This option cannot turn off globbing for particular pathspecs. That could eventually be done with a ":(noglob)" magic pathspec prefix. However, that level of granularity is more cumbersome to use for many cases, and doing ":(noglob)" right would mean converting the whole codebase to use "struct pathspec", as the usual "const char **pathspec" cannot represent extra per-item flags.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few error functions that simply wrap error() and provide a standardized message text. Like error(), they always return -1; knowing that can help the compiler silence some false positive -Wuninitialized warnings. One strategy would be to just declare these as inline in the header file so that the compiler can see that they always return -1. However, gcc does not always inline them (e.g., it will not inline opterror, even with -O3), which renders our change pointless. Instead, let's follow the same route we did with error() in the last patch, and define a macro that makes the constant return value obvious to the compiler.

This patch uses two variables instead of one, updates both when we set the "fallback" values, and updates them individually when we read from the environment.

A server using "parse_feature_request" could accomplish this with some extra parsing. You must skip past the "key" portion manually, check for "=" versus NUL or space, and then find the length by searching for the next space (or NUL). But clients can't even do that, since the "server_supports" interface does not even return the pointer. Instead, let's have our parser share more information by providing a pointer to the value and its length. The "parse_feature_value" function returns a pointer to the feature's value portion, along with the length of the value. If the feature is missing, NULL is returned. If it does not have an "=", then a zero-length value is returned. Similarly, "server_feature_value" behaves in the same way, but always checks the static server_feature_list variable. We can then implement "server_supports" in terms of "server_feature_value". We cannot implement the original "parse_feature_request" in terms of our new function, because it returned a pointer to the beginning of the feature. However, no callers actually cared about the value of the returned pointer, so we can simplify it to a boolean just as we do for "server_supports".

This will both give us a tiny bit of a performance enhancement when working with long pathnames and is a refactoring for more readability of the code. It enhances readability, by making it more clear what is a flag, and where the length is stored and make it clear which functions use stages in comparisions and which only use the length. It also makes CE_NAMEMASK private, so that users don't mistakenly write the name length in the flags.

There are many more places where we know what types of objects are called for. This patch adds support for "commit", "treeish", "tree", and "blob", which could be used in the following contexts: - "git apply --build-fake-ancestor" reads the "index" lines from the patch; they must name blob objects (not even "blob-ish"); - "git commit-tree" reads a tree object name (not "tree-ish"), and zero or more commit object names (not "committish"); - "git reset $rev" wants a committish; "git reset $rev -- $path" wants a treeish. They will come in later patches in the series. Signed-off-by: Junio C Hamano <gitster@pobox.com>
