| * refs.c: change resolve_ref_unsafe reading argument to be a flags fieldRonnie Sahlberg2014-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref resolves successfully for writing but not for reading). Change this to be a flags field instead, and pass the new constant RESOLVE_REF_READING when we want this behaviour. While at it, swap two of the arguments in the function to put output arguments at the end. As a nice side effect, this ensures that we can catch callers that were unaware of the new API so they can be audited. Give the wrapper functions resolve_refdup and read_ref_full the same treatment for consistency.

| | | | | | | | | | | | | | | | | | | | | | Change the ref transaction API so that we pass the reflog message to the create/delete/update functions instead of to ref_transaction_commit. This allows different reflog messages for each ref update in a multi-ref transaction.

|\ \ | |/ |/| | | | | | | | | | | Code cleanup. * jn/parse-config-slot: color_parse: do not mention variable name in error message pass config slots as pointers instead of offsets
| * color_parse: do not mention variable name in error messageJeff King2014-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally the color-parsing function was used only for config variables. It made sense to pass the variable name so that the die() message could be something like: $ git -c color.branch.plain=bogus branch fatal: bad color value 'bogus' for variable 'color.branch.plain' These days we call it in other contexts, and the resulting error messages are a little confusing: $ git log --pretty='%C(bogus)' fatal: bad color value 'bogus' for variable '--pretty format' $ git config --get-color foo.bar bogus fatal: bad color value 'bogus' for variable 'command line' This patch teaches color_parse to complain only about the value, and then return an error code. Config callers can then propagate that up to the config parser, which mentions the variable name. Other callers can provide a custom message. After this patch these three cases now look like: $ git -c color.branch.plain=bogus branch error: invalid color value: bogus fatal: unable to parse 'color.branch.plain' from command-line config $ git log --pretty='%C(bogus)' error: invalid color value: bogus fatal: unable to parse --pretty format $ git config --get-color foo.bar bogus error: invalid color value: bogus fatal: unable to parse default color value Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * pass config slots as pointers instead of offsetsJonathan Nieder2014-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many config-parsing helpers, like parse_branch_color_slot, take the name of a config variable and an offset to the "slot" name (e.g., "color.branch.plain" is passed along with "13" to effectively pass "plain"). This is leftover from the time that these functions would die() on error, and would want the full variable name for error reporting. These days they do not use the full variable name at all. Passing a single pointer to the slot name is more natural, and lets us more easily adjust the callers to use skip_prefix to avoid manually writing offset numbers. This is effectively a continuation of 9e1a5eb, which did the same for parse_diff_color_slot. This patch covers all of the remaining similar constructs.

* | | lockfile: change lock_file::filename into a strbufMichael Haggerty2014-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For now, we still make sure to allocate at least PATH_MAX characters for the strbuf because resolve_symlink() doesn't know how to expand the space for its return value. (That will be fixed in a moment.) Another alternative would be to just use a strbuf as scratch space in lock_file() but then store a pointer to the naked string in struct lock_file. But lock_file objects are often reused. By reusing the same strbuf, we can avoid having to reallocate the string most times when a lock_file object is reused.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When figuring out the author name for a commit, we may end up either pointing to const storage from getenv("GIT_AUTHOR_*"), or to newly allocated storage based on an existing commit or the --author option. Using const pointers to getenv's return has two problems: 1. It is not guaranteed that the return value from getenv remains valid across multiple calls. 2. We do not know whether to free the values at the end, so we just leak them. We can solve both by duplicating the string returned by getenv().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than parsing the header manually to find the "author" field, and then parsing its sub-parts, let's use find_commit_header and split_ident_line. This is shorter and easier to read, and should do a more careful parsing job. For example, the current parser could find the end-of-email right-bracket across a newline (for a malformed commit), and calculate a bogus gigantic length for the date (by using "eol - rb"). As a bonus, this also plugs a memory leak when we pull the date field from an existing commit (we still leak the name and email buffers, which will be fixed in a later commit).

| * | date: use strbufs in date-formatting functionsJeff King2014-08-27
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the date functions write into fixed-size buffers. This is a minor pain, as we have to take special precautions, and frequently end up copying the result into a strbuf or heap-allocated buffer anyway (for which we sometimes use strcpy!). Let's instead teach parse_date, datestamp, etc to write to a strbuf. The obvious downside is that we might need to perform a heap allocation where we otherwise would not need to. However, it turns out that the only two new allocations required are: 1. In test-date.c, where we don't care about efficiency. 2. In determine_author_info, which is not performance critical (and where the use of a strbuf will help later refactoring).

While this is nice and simple, in practice it makes it hard to use for two reasons: 1. When you want to conditionally skip or keep the string as-is, you have to introduce a temporary variable. For example: tmp = skip_prefix(buf, "foo"); if (tmp) buf = tmp; 2. It is verbose to check the outcome in a conditional, as you need extra parentheses to silence compiler warnings. For example: if ((cp = skip_prefix(buf, "foo")) /* do something with cp */ Both of these make it harder to use for long if-chains, and we tend to use starts_with() instead. However, the first line of "do something" is often to then skip forward in buf past the prefix, either using a magic constant or with an extra strlen(3) (which is generally computed at compile time, but means we are repeating ourselves). This patch refactors skip_prefix() to return a simple boolean, and to provide the pointer value as an out-parameter. If the prefix is not found, the out-parameter is untouched. This lets you write: if (skip_prefix(arg, "foo ", &arg)) do_foo(arg); else if (skip_prefix(arg, "bar ", &arg)) do_bar(arg); Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

It's easy to turn a strbuf into such a pair (by dereferencing its members), but less easy to go the other way (you can strbuf_attach, but that has implications about memory ownership). This patch teaches commit_tree (and its associated callers and sub-functions) to take such a pair for the commit message rather than a strbuf. This makes passing the buffer around slightly more verbose, but means we can get rid of some dangerous strbuf_attach calls in the next patch.

This is a backward-incompatible change, but should be so in a good way (aka bugfix). * jl/status-added-submodule-is-never-ignored: commit -m: commit staged submodules regardless of ignore config status/commit: show staged submodules regardless of ignore config

But when commit doesn't generate the status output (e.g. when used in a script with '-m') the ignored submodule will still not be committed. This is because in that case a different code path is taken which calls index_differs_from() instead of calling the wt_status functions. Fix that by calling index_differs_from() from builtin/commit.c with a diff_options argument value that tells it not ignore any submodule changes unless the '--ignore-submodules' option is used. Even though this option isn't yet implemented for cmd_commit() but only for cmd_status() this prepares cmd_commit() to correctly handle the '--ignore-submodules' option later. As status and commit share the same ignore_submodule_arg variable this makes the code more robust against accidental breakage and documents how to correctly call index_differs_from(). Change the expected result of the test documenting this problem from failure to success. Signed-off-by: Jens Lehmann <Jens.Lehmann@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This should stop surprises because git strips some lines unexpectedly. Note that git is not smart enough to recognize '#' as the comment char in custom templates and convert it if the final comment char is different. It thinks '#' lines in custom templates as part of the commit message. So don't use this with custom templates.

However, this check is redundant and harmful. It's redundant because we will already notice the empty message later, after we would have run the editor, and die there (just as we would for a regular, not "-C" case, where the user provided an empty message in the editor). It's harmful for a few reasons: 1. It does not respect --allow-empty-message. As a result, a "git rebase -i" cannot "pick" such a commit. So you cannot even go back in time to fix it with a "reword" or "edit" instruction. 2. It does not take into account other ways besides the editor to modify the message. For example, "git commit -C empty-commit -m foo" could take the author information from empty-commit, but add a message to it. There's more to do to make that work correctly (and right now we explicitly forbid "-C with -m"), but this removes one roadblock. 3. The existing check is not enough to prevent segfaults. We try to find the "\n\n" header/body boundary in the commit. If it is at the end of the string (i.e., no body), _or_ if we cannot find it at all (i.e., a truncated commit object), we consider the message empty. With "-C", that's OK; we die in either case. But with "-c", we continue on, and in the case of a truncated commit may end up dereferencing NULL+2. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

However, this means obvious things like "--date=now" or "--date=2.days.ago" will not work. Instead, let's fallback to the approxidate function to handle this for us. Note that we must try parse_date ourselves first, even though approxidate will try strict parsing itself. The reason is that approxidate throws away any timezone information it sees from the strict parsing, and we want to preserve it. So asking for: git commit --date="@1234567890 -0700" continues to set the date in -0700, regardless of what the local timezone is.
