2019-11-14diff: export diffstat interfaceLibravatar Daniel Ferreira1-23/+16
Make the diffstat interface (namely, the diffstat_t struct and compute_diffstat) no longer be internal to diff.c and allow it to be used by other parts of git. This is helpful for code that may want to easily extract information from files using the diff machinery, while flushing it differently from how the show_* functions used by diff_flush() do it. One example is the builtin implementation of git-add--interactive's status.

2019-10-07hashmap: remove type arg from hashmap_{get,put,remove}_entryLibravatar Eric Wong1-4/+2
Since these macros already take a `keyvar' pointer of a known type, we can rely on OFFSETOF_VAR to get the correct offset without relying on non-portable `__typeof__' and `offsetof'. Argument order is also rearranged, so `keyvar' and `member' are sequential as they are used as: `keyvar->member' Signed-off-by: Eric Wong <e@80x24.org> Reviewed-by: Derrick Stolee <stolee@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-10-07OFFSETOF_VAR macro to simplify hashmap iteratorsLibravatar Eric Wong1-3/+2
While we cannot rely on a `__typeof__' operator being portable to use with `offsetof'; we can calculate the pointer offset using an existing pointer and the address of a member using pointer arithmetic for compilers without `__typeof__'. This allows us to simplify usage of hashmap iterator macros by not having to specify a type when a pointer of that type is already given. In the future, list iterator macros (e.g. list_for_each_entry) may also be implemented using OFFSETOF_VAR to save hackers the trouble of using container_of/list_entry macros and without relying on non-portable `__typeof__'. v3: use `__typeof__' to avoid clang warnings Signed-off-by: Eric Wong <e@80x24.org> Reviewed-by: Derrick Stolee <stolee@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-10-07hashmap: introduce hashmap_free_entriesLibravatar Eric Wong1-2/+4
`hashmap_free_entries' behaves like `container_of' and passes the offset of the hashmap_entry struct to the internal `hashmap_free_' function, allowing the function to free any struct pointer regardless of where the hashmap_entry field is located. `hashmap_free' no longer takes any arguments aside from the hashmap itself.

2019-10-07hashmap: use *_entry APIs to wrap container_ofLibravatar Eric Wong1-12/+9
Using `container_of' can be verbose and choosing names for intermediate "struct hashmap_entry" pointers is a hard problem. So introduce "*_entry" APIs inspired by similar linked-list APIs in the Linux kernel. Unfortunately, `__typeof__' is not portable C, so we need an extra parameter to specify the type.

In 7fbbcb21b1 ("diff: batch fetching of missing blobs", 2019-04-08), diff was taught to batch the fetching of missing objects when operating on a partial clone, but was not taught to refrain from fetching GITLINKs. Teach diff to check if an object is a GITLINK before including it in the set to be fetched. (As stated in the commit message of that commit, unpack-trees was also taught a similar thing prior, but unpack-trees correctly checks for GITLINK before including objects in the set to be fetched.)

2019-07-11range-diff: suppress line count in outer diffLibravatar Thomas Gummerer1-1/+4
The line count in the outer diff's hunk headers of a range diff is not all that interesting. It merely shows how far along the inner diff are on both sides. That number is of no use for human readers, and range-diffs are not meant to be machine readable. In a subsequent commit we're going to add some more contextual information such as the filename corresponding to the diff to the hunk headers. Remove the unnecessary information, and just keep the "@@" to indicate that a new hunk of the outer diff is starting.

2019-07-11diff: munmap() file contents before running external diffLibravatar Johannes Schindelin1-0/+2
When running an external diff from, say, a diff tool, it is safe to assume that we want to write the files in question. On Windows, that means that there cannot be any other process holding an open handle to said files, or even just a mapped region. So let's make sure that `git diff` itself is not holding any open handle to the files in question. In fact, we will just release the file pair right away, as the external diff uses the files we just wrote, so we do not need to hold the file contents in memory anymore.

Instead of using the repository_format_partial_clone global and fetch_objects() directly, let's use has_promisor_remote() and promisor_remote_get_direct(). This way all the configured promisor remotes will be taken into account, not only the one specified by extensions.partialClone. Also when cloning or fetching using a partial clone filter, remote.origin.promisor will be set to "true" instead of setting extensions.partialClone to "origin". This makes it possible to use many promisor remote just by fetching from them. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Before d473e2e0e8 (diff.c: convert -U|--unified, 2019-01-27), -U and --unified are implemented with a custom parser opt_arg() in diff.c. I didn't check this code carefully and not realize that it's the equivalent of PARSE_OPT_NONEG | PARSE_OPT_OPTARG. In other words, if -U is specified without any argument, the option should be accepted, and the default value should be used. Without PARSE_OPT_OPTARG, parse_options() will reject this case and cause a regression.
