To libify `git apply` functionality we have to signal errors to the caller instead of die()ing. To do that in a compatible manner with the rest of the error handling in "builtin/apply.c", gitdiff_*() functions should return -1 instead of calling die(). A previous patch made it possible for gitdiff_*() functions to return -1 in case of error. Let's take advantage of that to make gitdiff_verify_name() return -1 on error, and to have gitdiff_oldname() and gitdiff_newname() directly return what gitdiff_verify_name() returns.

2016-08-11builtin/apply: make gitdiff_*() return 1 at end of headerLibravatar Christian Couder1-3/+9
The gitdiff_*() functions that are called as p->fn() in parse_git_header() should return 1 instead of -1 in case of end of header or unrecognized input, as these are not real errors. It just instructs the parser to break out. This makes it possible for gitdiff_*() functions to return -1 in case of a real error. This will be done in a following patch.

2016-08-11builtin/apply: make apply_all_patches() return 128 or 1 on errorLibravatar Christian Couder1-11/+26
To finish libifying the apply functionality, apply_all_patches() should not die() or exit() in case of error, but return either 128 or 1, so that it gives the same exit code as when die() or exit(1) is called. This way scripts relying on the exit code don't need to be changed. While doing that we must take care that file descriptors are properly closed and, if needed, reset to a sensible value. Also, according to the lockfile API, when finished with a lockfile, one should either commit it or roll it back. This is even more important now that the same lockfile can be passed to init_apply_state() many times to be reused by series of calls to the apply lib functions.

2016-07-18fsck: optionally show more helpful info for broken linksLibravatar Johannes Schindelin1-4/+38
When reporting broken links between commits/trees/blobs, it would be quite helpful at times if the user would be told how the object is supposed to be reachable. With the new --name-objects option, git-fsck will try to do exactly that: name the objects in a way that shows how they are reachable. For example, when some reflog got corrupted and a blob is missing that should not be, the user might want to remove the corresponding reflog entry. This option helps them find that entry: `git fsck` will now report something like this: broken link from tree b5eb6ff... (refs/stash@{<date>}~37:) to blob ec5cf80...

2016-07-18blame: allow to blame paths freshly added to the indexLibravatar Mike Hommey1-1/+9
When blaming files, changes in the work tree are taken into account and displayed as being "Not Committed Yet". However, when blaming a file that is not known to the current HEAD, git blame fails with `no such path 'foo' in HEAD`, even when the file was git add'ed. Allowing such a blame is useful when the new file added to the index (not yet committed) was created by renaming an existing file. It also is useful when the new file was created from pieces already in HEAD, moved or copied from other files and blaming with copy detection (i.e. "-C").

2016-07-13fsck: use streaming interface for large blobs in packLibravatar Nguyễn Thái Ngọc Duy1-0/+4
For blobs, we want to make sure the on-disk data is not corrupted (i.e. can be inflated and produce the expected SHA-1). Blob content is opaque, there's nothing else inside to check for. For really large blobs, we may want to avoid unpacking the entire blob in memory, just to check whether it produces the same SHA-1. On 32-bit systems, we may not have enough virtual address space for such memory allocation. And even on 64-bit where it's not a problem, allocating a lot more memory could result in kicking other parts of systems to swap file, generating lots of I/O and slowing everything down. For this particular operation, not unpacking the blob and letting check_sha1_signature, which supports streaming interface, do the job is sufficient. check_sha1_signature() is not shown in the diff, unfortunately. But if will be called when "data_valid && !data" is false. We will call the callback function "fn" with NULL as "data". The only callback of this function is fsck_obj_buffer(), which does not touch "data" at all if it's a blob.

2016-07-13pack-objects: do not truncate result in-pack object size on 32-bit systemsLibravatar Nguyễn Thái Ngọc Duy1-7/+8
A typical diff will not show what's going on and you need to see full functions. The core code is like this, at the end of of write_one() e->idx.offset = *offset; size = write_object(f, e, *offset); if (!size) { e->idx.offset = recursing; return WRITE_ONE_BREAK; } written_list[nr_written++] = &e->idx; /* make sure off_t is sufficiently large not to wrap */ if (signed_add_overflows(*offset, size)) die("pack too large for current definition of off_t"); *offset += size; Here we can see that the in-pack object size is returned by write_object (or indirectly by write_reuse_object). And it's used to calculate object offsets, which end up in the pack index file, generated at the end. If "size" overflows (on 32-bit sytems, unsigned long is 32-bit while off_t can be 64-bit), we got wrong offsets and produce incorrect .idx file, which may make it look like the .pack file is corrupted.

2016-07-13index-pack: correct "offset" type in unpack_entry_data()Libravatar Nguyễn Thái Ngọc Duy1-1/+1
unpack_entry_data() receives an off_t value from unpack_raw_entry(), which could be larger than unsigned long on 32-bit systems with large file support. Correct the type so truncation does not happen. This only affects bad object reporting though.

2016-07-13index-pack: report correct bad object offsets even if they are largeLibravatar Nguyễn Thái Ngọc Duy1-3/+4
Use the right type for offsets in this case, off_t, which makes a difference on 32-bit systems with large file support, and change formatting code accordingly. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-07-13index-pack: correct "len" type in unpack_data()Libravatar Nguyễn Thái Ngọc Duy1-7/+7
On 32-bit systems with large file support, one entry could be larger than 4GB and overflow "len". Correct it so we can unpack a full entry. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-07-13sha1_file.c: use type off_t* for object_info->disk_sizepLibravatar Nguyễn Thái Ngọc Duy1-2/+2
This field, filled by sha1_object_info() contains the on-disk size of an object, which could go over 4GB limit of unsigned long on 32-bit systems. Use off_t for it instead and update all callers.

Don't throw the memory allocated for remove_dir_recursively() away after a single call, use it for the other entries as well instead. Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
