We currently have seven callers of `reduce_heads(foo)`. Six of them do not use the original list `foo` again, and actually, all six of those end up leaking it. Introduce and use `reduce_heads_replace(&foo)` as a leak-free version of `foo = reduce_heads(foo)` to fix several of these. Fix the remaining leaks using `free_commit_list()`. While we're here, document `reduce_heads()` and mark it as `extern`. Signed-off-by: NMartin Ågren <martin.agren@gmail.com> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Old implementation determined number of hashes by dividing length of line by length of hash, which works only if all hash representations have same length. New graft line parser works in two phases: 1. In first phase line is scanned to verify correctness and compute number of hashes, then graft struct is allocated. 2. In second phase line is scanned again to fill up already allocated graft struct. This way graft parsing code can support different sizes of hashes without any further code adaptations. A number of alternative implementations were considered and discarded: - Modifying graft structure to store oid_array instead of FLEXI_ARRAY indicates undesirable usage of struct to readers. - Parsing into temporary string_list or oid_array complicates code by adding more return paths, as these structures needs to be cleared before returning from function. - Determining number of hashes by counting separators might cause maintenance issues, if this function needs to be modified in future again.

Simplify the code for moving members inside of an array and make it more robust by using the helper macro MOVE_ARRAY. It calculates the size based on the specified number of elements for us and supports NULL pointers when that number is zero. Raw memmove(3) calls with NULL can cause the compiler to (over-eagerly) optimize out later NULL checks. This patch was generated with contrib/coccinelle/array.cocci and spatch (Coccinelle).

This makes it consistent with how "git commit -v -s" inserts a new Signed-off-by: line. This can be done by the same logic as the existing helper function, wt_status_truncate_message_at_cut_line(), uses, but it wants the caller to pass a strbuf to it. Because the function ignore_non_trailer() used by the command takes a <pointer, length> pair, not a strbuf, steal the logic from wt_status_truncate_message_at_cut_line() to create a new wt_status_locate_end() helper function that takes <pointer, length> pair, and make ignore_non_trailer() call it to help "interpret-trailers". Since there is only one caller of wt_status_truncate_message_at_cut_line() in cmd_commit(), rewrite it to call wt_status_locate_end() helper instead and remove the old helper that no longer has any caller.

Git's source code assumes that unsigned long is at least as precise as time_t. Which is incorrect, and causes a lot of problems, in particular where unsigned long is only 32-bit (notably on Windows, even in 64-bit versions). So let's just use a more appropriate data type instead. In preparation for this, we introduce the new `timestamp_t` data type. By necessity, this is a very, very large patch, as it has to replace all timestamps' data type in one go. As we will use a data type that is not necessarily identical to `time_t`, we need to be very careful to use `time_t` whenever we interact with the system functions, and `timestamp_t` everywhere else.

When we call parse_commit, it will complain to stderr if the object does not exist or cannot be read. This means that we may produce useless error messages if this situation is expected (e.g., because the object is marked UNINTERESTING, or because revs->ignore_missing_links is set). We can fix this by adding a new "parse_X_gently" form that takes a flag to suppress the messages. The existing "parse_X" form is already gentle in the sense that it returns an error rather than dying, and we could in theory just add a "quiet" flag to it (with existing callers passing "0"). But doing it this way means we do not have to disturb existing callers. Note also that the new flag is "quiet_on_missing", and not just "quiet". We could add a flag to suppress _all_ errors, but besides being a more invasive change (we would have to pass the flag down to sub-functions, too), there is a good reason not to: we would never want to use it. Missing a linked object is expected in some circumstances, but it is never expected to have a malformed commit, or to get a tree when we wanted a commit. We should always complain about these corruptions. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

There is no API to ask "Does this commit have associated data in slab?". If an application wants to (1) parse just a few commits at the beginning of a process, (2) store data for only these commits, and then (3) start processing many commits, taking into account the data stored (for a few of them) in the slab, the application would use slabname##_at() to allocate a space to store data in (2), but there is no API other than slabname##_at() to use in step (3). This allocates and wastes new space for these commits the caller is only interested in checking if they have data stored in step (2). Introduce slabname##_peek(), which is similar to slabname##_at() but returns NULL when there is no data already associated to it in such a use case.
