This started as a complex new test for checkout going through the
"typechanges" test repository, but that revealed numerous issues
with checkout, including:
* complete failure with submodules
* failure to create blobs with exec bits
* problems when replacing a tree with a blob because the tree
"example/" sorts after the blob "example" so the delete was
being processed after the single file blob was created
This fixes most of those problems and includes a number of other
minor changes that made it easier to do that, including improving
the TYPECHANGE support in diff/status, etc.

The adds a test for the submodule diff capabilities and then
fixes a few bugs with how the output is generated. It improves
the accuracy of OIDs in the diff delta object and makes the
submodule output more closely mirror the OIDs that will be used
by core git.

There are a few cases where diff should leave directories in
the diff list if we want to match core git, such as when the
directory contains a .git dir. That feature was lost when I
introduced some of the new submodule handling.
This restores that and then fixes a couple of related to diff
output that are triggered by having diffs with directories in
them.
Also, this adds a new flag that can be passed to diff if you
want diff output to actually include the file content of any
untracked files.

1. teach diff.c:maybe_modified to query git_submodule_status for the
modification state of a submodule. According to the
git_submodule_status docs, it will filter for to-ignore states
already.
2. teach diff_output.c:get_workdir_content to check the submodule status
again and create a line like:
Subproject commit <SHA-1>\n
or
Subproject comimt <SHA-1>-dirty\n
like git.git does.

diff_output.c:get_blob_content used to try to read the submodule commit
as a blob in the superproject's odb. Of course it cannot find it and
errors out with GIT_ENOTFOUND, implcitly terminating the whole diff
output.
This patch teaches it to create a text that describes the submodule
instead. The text looks like:
Subproject commit <SHA1>\n
which is what git.git does, too.

There are a lot of places where the diff API gives the user access
to internal data structures and many of these were being exposed
through non-const pointers. This replaces them all with const
pointers for any object that the user can access but is still
owned internally to the git_diff_list or git_diff_patch objects.
This will probably break some bindings... Sorry!

This fixes all the bugs in the new diff patch code. The only
really interesting one is that when we merge two diffs, we now
have to actually exclude diff delta records that are not supposed
to be tracked, as opposed to before where they could be included
because they would be skipped silently by `git_diff_foreach()`.
Other than that, there are just minor errors.

Replacing the `git_iterator` object, this creates a simple API
for accessing the "patch" for any file pair in a diff list and
then gives indexed access to the hunks in the patch and the lines
in the hunk. This is the initial implementation of this revised
API - it is still broken, but at least builds cleanly.
|
| | |
|
| |
|
|
|
|
| |
The last change tweaked the way we use the hunk_curr pointer
during iteration, but failed to reset the value back to NULL
when switching files.
|
| |
|
|
|
|
|
| |
There is a bug in building the linked list of line records in the
diff iterator and also an off by one element error in the hunk
counts. This fixes both of these, adds some test data with more
complex sets of hunk and line diffs to exercise this code better.

In the process of adding tests for the max file size threshold
(which treats files over a certain size as binary) there seem to
be a number of problems in the new code with detecting binaries.
This should fix those up, as well as add a test for the file
size threshold stuff.
Also, this un-deprecates `GIT_DIFF_LINE_ADD_EOFNL`, since I
finally found a legitimate situation where it would be returned.

Often `git_odb_read_header` will "fail" and have to read the
entire object into memory instead of just the header. When this
happens, the object is loaded and then disposed of immediately,
which makes it difficult to efficiently use the header information
to decide if the object should be loaded (since attempting to do
so will often result in loading the object twice).
This commit takes the existing code and reorganizes it to have
two new functions:
- `git_odb__read_header_or_object` which acts just like the old
read header function except that it returns the object, too, if
it was forced to load the whole thing. It then becomes the
callers responsibility to free the `git_odb_object`.
- `git_object__from_odb_object` which was extracted from the old
`git_object_lookup` and creates a subclass of `git_object` from
an existing `git_odb_object` (separating the ODB lookup from the
`git_object` creation). This allows you to use the first header
reading function efficiently without instantiating the
`git_odb_object` twice.
There is no net change to the behavior of any of the existing
functions, but this allows internal code to tap into the ODB
lookup and object creation to be more efficient.

This commit adds a max_size value in the public `git_diff_options`
structure so that the user can automatically flag blobs over a
certain size as binary regardless of other properties.
Also, and perhaps more importantly, this moves binary detection
to be as early as possible in the diff traversal inner loop and
makes sure that we stop loading objects as soon as we decide that
they are binary.

The `git_diff_iterator_num_files` API was problematic, since we
don't actually know the exact number of files to be iterated over
until we load those files into memory. This replaces it with a
new `git_diff_iterator_progress` API that goes from 0 to 1, and
moves and renamed the old API for the internal places that can
tolerate a max value instead of an exact value.

Previously when diffing blobs, the diff code just ran with a NULL
repository object. Of course, that's not necessary and the test
for a NULL repo was confusing. This makes the blob diff run with
the repo that contains the blobs and clarifies the test that it
is possible to be diffing data where the path is unknown.

This adds support to diff and status for running filters (a la crlf)
on blobs in the workdir before computing SHAs and before generating
text diffs. This ended up being a bit more code change than I had
thought since I had to reorganize some of the diff logic to minimize
peak memory use when filtering blobs in a diff.
This also adds a cap on the maximum size of data that will be loaded
to diff. I set it at 512Mb which should match core git. Right now
it is a #define in src/diff.h but it could be moved into the public
API if desired.

This adds better header comments and also fixes a bug in one of
simple APIs that tells the number of lines in the current hunk.

This refactors the diff output code so that an iterator object
can be used to traverse and generate the diffs, instead of just
the `foreach()` style with callbacks. The code has been rearranged
so that the two styles can still share most functions.
This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses
that as a common error code for marking the end of iteration when
using a iterator style of object.

This is a big redesign of the git_submodule_status API and the
implementation of the redesigned API. It also fixes a number of
bugs that I found in other parts of the submodule API while
writing the tests for the status part.
This also fixes a couple of bugs in the iterators that had not
been noticed before - one with iterating when there is a gitlink
(i.e. separate-work-dir) and one where I was treating anything
even vaguely submodule-like as a submodule, more aggressively
than core git does.

In looking at PR #878, I found a few small bugs in the diff code,
mostly related to work that can be avoided when processing tree-
to-tree diffs that was always being carried out. This commit has
some small fixes in it.

This updates all the `foreach()` type functions across the library
that take callbacks from the user to have a consistent behavior.
The rules are:
* A callback terminates the loop by returning any non-zero value
* Once the callback returns non-zero, it will not be called again
(i.e. the loop stops all iteration regardless of state)
* If the callback returns non-zero, the parent fn returns GIT_EUSER
* Although the parent returns GIT_EUSER, no error will be set in
the library and `giterr_last()` will return NULL if called.
This commit makes those changes across the library and adds tests
for most of the iteration APIs to make sure that they follow the
above rules.

There are three actual changes in this commit:
1. When the trailing newline of a file is removed in a diff, the
change will now be reported with `GIT_DIFF_LINE_DEL_EOFNL` passed
to the callback. Previously, the `ADD_EOFNL` constant was given
which was just an error in my understanding of when the various
circumstances arose. `GIT_DIFF_LINE_ADD_EOFNL` is deprecated and
should never be generated. A new newline is simply an `ADD`.
2. Rewrote the `diff_delta__merge_like_cgit` function that contains
the core logic of the `git_diff_merge` implementation. The new
version doesn't actually have significantly different behavior,
but the logic should be much more obvious, I think.
3. Fixed a bug in `git_diff_merge` where it freed a string pool
while some of the string data was still in use. This led to
`git_diff_print_patch` accessing memory that had been freed.
The rest of this commit contains improved documentation in `diff.h`
to make the behavior and the equivalencies with core git clearer,
and a bunch of new tests to cover the various cases, oh and a minor
simplification of `examples/diff.c`.

File modes were both not being ignored properly on platforms
where they should be ignored, nor be diffed consistently on
platforms where they are supported.
This change adds a number of diff and status filemode change
tests. This also makes sure that filemode-only changes are
included in the diff output when they occur and that filemode
changes are ignored successfully when core.filemode is false.
There is no code that automatically toggles core.filemode
based on the capabilities of the current platform, so the user
still needs to be careful in their .git/config file.

GProf shows `git_text_gather_stats` as the most expensive call
in large diffs. The function calculates a lot of information
that is not actually used and does not do so in a optimal
order. This introduces a tuned `git_buf_is_binary` function
that executes the same algorithm in a fraction of the time.

Depending on the operation, we need to consider gitattributes
in both the work dir and the index. This adds a parameter to
all of the gitattributes related functions that allows user
control of attribute reading behavior (i.e. prefer workdir,
prefer index, only use index).
This fix also covers allowing us to check attributes (and
hence do diff and status) on bare repositories.
This was a somewhat larger change that I hoped because it had
to change the cache key used for gitattributes files.

Since strnlen is not supported on all platforms and since we
now have the shiny new git_text_is_binary in the filtering
code, let's convert diff binary detection to use the new stuff.
|

| |
| |
| |
| |

To make this code more resilient to future changes, we'll
explicitly translate the libgit2 structure to the libxdiff
structure.
|
| | |
| |
| |
| |
| |
| |
| |
| | |
This should restore the ability to include libgit2 headers
in C++ projects.

This adds support for roughly-right tracking of submodules
(although it does not recurse into submodules to detect
internal modifications a la core git), and it adds support
for including unmodified files in diff iteration if requested.

to work right.

This also includes droping `git_buf_lasterror` because it makes no sense
in the new system. Note that in most of the places were it has been
dropped, the code needs cleanup. I.e. GIT_ENOMEM is going away, so
instead it should return a generic `-1` and obviously not throw
anything.
