2018-08-13attr: remove index from git_attr_set_direction()Libravatar Nguyễn Thái Ngọc Duy1-1/+1
Since attr checking API now take the index, there's no need to set an index in advance with this call. Most call sites are straightforward because they either pass the_index or NULL (which defaults back to the_index previously). There's only one suspicious call site in unpack-trees.c where it sets a different index. This code in unpack-trees is about to check out entries from the new/temporary index after merging is done in it. The attributes will be used by entry.c code to do crlf conversion if needed. entry.c now respects struct checkout's istate field, and this field is correctly set in unpack-trees.c, there should be no regression from this change.

2018-08-13attr: remove an implicit dependency on the_indexLibravatar Nguyễn Thái Ngọc Duy1-1/+1
Make the attr API take an index_state instead of assuming the_index in attr code. All call sites are converted blindly to keep the patch simple and retain current behavior. Individual call sites may receive further updates to use the right index instead of the_index. There is one ugly temporary workaround added in attr.c that needs some more explanation. Commit c24f3abace (apply: file commited with CRLF should roundtrip diff and apply - 2017-08-19) forces one convert_to_git() call to NOT read the index at all. But what do you know, we read it anyway by falling back to the_index. When "istate" from convert_to_git is now propagated down to read_attr_from_array() we will hit segfault somewhere inside read_blob_data_from_index. The right way of dealing with this is to kill "use_index" variable and only follow "istate" but at this stage we are not ready for that: while most git_attr_set_direction() calls just passes the_index to be assigned to use_index, unpack-trees passes a different one which is used by entry.c code, which has no way to know what index to use if we delete use_index. So this has to be done later. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Add a repository argument to allow callers of lookup_commit_reference_gently to be more specific about which repository to handle.

2017-09-25Merge branch 'rs/archive-excluded-directory'Libravatar Junio C Hamano1-17/+2
"git archive", especially when used with pathspec, stored an empty directory in its output, even though Git itself never does so. This has been fixed. * rs/archive-excluded-directory: archive: don't add empty directories to archives
2017-09-14archive: don't add empty directories to archivesLibravatar René Scharfe1-17/+2
While git doesn't track empty directories, git archive can be tricked into putting some into archives. One way is to construct an empty tree object, as t5004 does. While that is supported by the object database, it can't be represented in the index and thus it's unlikely to occur in the wild. Another way is using the literal name of a directory in an exclude pathspec -- its contents are are excluded, but the directory stub is included. That's inconsistent: exclude pathspecs containing wildcards don't leave empty directories in the archive. Yet another way is have a few levels of nested subdirectories (e.g. d1/d2/d3/file1) and ignoring the entries at the leaves (e.g. file1). The directories with the ignored content are ignored as well (e.g. d3), but their empty parents are included (e.g. d2). As empty directories are not supported by git, they should also not be written into archives. If an empty directory is really needed then it can be tracked and archived by placing an empty .gitignore file in it. There already is a mechanism in place for suppressing empty directories. When read_tree_recursive() encounters a directory excluded by a pathspec then it enters it anyway because it might contain included entries. It calls the callback function before it is able to decide if the directory is actually needed. For that reason git archive adds directories to a queue and writes entries for them only when it encounters the first child item -- but currently only if pathspecs with wildcards are used. Queue *all* directories, no matter if there even are pathspecs present. This prevents git archive from writing entries for empty directories in all cases.

This prevents read_tree_recursive() from descending into them and this avoids write_archive_entry() rejecting them later on, which queue_or_write_archive_entry() is not prepared for.

Convert lookup_commit, lookup_commit_or_die, lookup_commit_reference, and lookup_commit_reference_gently to take struct object_id arguments.

2015-10-05avoid sprintf and strcpy with flex arraysLibravatar Jeff King1-2/+3
When we are allocating a struct with a FLEX_ARRAY member, we generally compute the size of the array and then sprintf or strcpy into it. Normally we could improve a dynamic allocation like this by using xstrfmt, but it doesn't work here; we have to account for the size of the rest of the struct. But we can improve things a bit by storing the length that we use for the allocation, and then feeding it to xsnprintf or memcpy, which makes it more obvious that we are not writing more than the allocated number of bytes. It would be nice if we had some kind of helper for allocating generic flex arrays, but it doesn't work that well: - the call signature is a little bit unwieldy: d = flex_struct(sizeof(*d), offsetof(d, path), fmt, ...); You need offsetof here instead of just writing to the end of the base size, because we don't know how the struct is packed (partially this is because FLEX_ARRAY might not be zero, though we can account for that; but the size of the struct may actually be rounded up for alignment, and we can't know that). - some sites do clever things, like over-allocating because they know they will write larger things into the buffer later (e.g., struct packed_git here). So we're better off to just write out each allocation (or add type-specific helpers, though many of these are one-off allocations anyway).

2015-06-29convert "enum date_mode" into a structLibravatar Jeff King1-1/+1
In preparation for adding date modes that may carry extra information beyond the mode itself, this patch converts the date_mode enum into a struct. Most of the conversion is fairly straightforward; we pass the struct as a pointer and dereference the type field where necessary. Locations that declare a date_mode can use a "{}" constructor. However, the tricky case is where we use the enum labels as constants, like: show_date(t, tz, DATE_NORMAL); Ideally we could say: show_date(t, tz, &{ DATE_NORMAL }); but of course C does not allow that. Likewise, we cannot cast the constant to a struct, because we need to pass an actual address. Our options are basically: 1. Manually add a "struct date_mode d = { DATE_NORMAL }" definition to each caller, and pass "&d". This makes the callers uglier, because they sometimes do not even have their own scope (e.g., they are inside a switch statement). 2. Provide a pre-made global "date_normal" struct that can be passed by address. We'd also need "date_rfc2822", "date_iso8601", and so forth. But at least the ugliness is defined in one place. 3. Provide a wrapper that generates the correct struct on the fly. The big downside is that we end up pointing to a single global, which makes our wrapper non-reentrant. But show_date is already not reentrant, so it does not matter. This patch implements 3, along with a minor macro to keep the size of the callers sane.

2015-01-14standardize usage info string formatLibravatar Alex Henrie1-2/+2
This patch puts the usage info strings that were not already in docopt- like format into docopt-like format, which will be a litle easier for end users and a lot easier for translators. Changes include: - Placing angle brackets around fill-in-the-blank parameters - Putting dashes in multiword parameter names - Adding spaces to [-f|--foobar] to make [-f | --foobar] - Replacing <foobar>* with [<foobar>...] Signed-off-by: Alex Henrie <alexhenrie24@gmail.com> Reviewed-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-12-01tree.c: update read_tree_recursive callback to pass strbuf as baseLibravatar Nguyễn Thái Ngọc Duy1-13/+21
This allows the callback to use 'base' as a temporary buffer to quickly assemble full path "without" extra allocation. The callback has to restore it afterwards of course.

"git archive" learned to filter what gets archived with pathspec. * nd/archive-pathspec: archive: support filtering paths with glob
2014-09-22archive: support filtering paths with globLibravatar Nguyễn Thái Ngọc Duy1-3/+94
This patch fixes two problems with using :(glob) (or even "*.c" without ":(glob)"). The first one is we forgot to turn on the 'recursive' flag in struct pathspec. Without that, tree_entry_interesting() will not mark potential directories "interesting" so that it can confirm whether those directories have anything matching the pathspec. The marking directories interesting has a side effect that we need to walk inside a directory to realize that there's nothing interested in there. By that time, 'archive' code has already written the (empty) directory down. That means lots of empty directories in the result archive. This problem is fixed by lazily writing directories down when we know they are actually needed. There is a theoretical bug in this implementation: we can't write empty trees/directories that match that pathspec. path_exists() is also made stricter in order to detect non-matching pathspec because when this 'recursive' flag is on, we most likely match some directories. The easiest way is not consider any directories "matched".

2014-02-28add uploadarchive.allowUnreachable optionLibravatar Scott J. Goldman1-2/+11
In commit ee27ca4, we started restricting remote git-archive invocations to only accessing reachable commits. This matches what upload-pack allows, but does restrict some useful cases (e.g., HEAD:foo). We loosened this in 0f544ee, which allows `foo:bar` as long as `foo` is a ref tip. However, that still doesn't allow many useful things, like: 1. Commits accessible from a ref, like `foo^:bar`, which are reachable 2. Arbitrary sha1s, even if they are reachable. We can do a full object-reachability check for these cases, but it can be quite expensive if the client has sent us the sha1 of a tree; we have to visit every sub-tree of every commit in the worst case. Let's instead give site admins an escape hatch, in case they prefer the more liberal behavior. For many sites, the full object database is public anyway (e.g., if you allow dumb walker access), or the site admin may simply decide the security/convenience tradeoff is not worth it. This patch adds a new config option to disable the restrictions added in ee27ca4. It defaults to off, meaning there is no change in behavior by default.
