The contents of the .gitattributes files may evolve over time, but "git
check-attr" always checks attributes against them in the working tree
and/or in the index. It may be beneficial to optionally allow the users
to check attributes taken from a commit other than HEAD against paths.
Add a new flag `--source` which will allow users to check the
attributes against a commit (actually any tree-ish would do). When the
user uses this flag, we go through the stack of .gitattributes files but
instead of checking the current working tree and/or in the index, we
check the blobs from the provided tree-ish object. This allows the
command to also be used in bare repositories.
Since we use a tree-ish object, the user can pass "--source
HEAD:subdirectory" and all the attributes will be looked up as if
subdirectory was the root directory of the repository.
We cannot simply use the `<rev>:<path>` syntax without the `--source`
flag, similar to how it is used in `git show` because any non-flag
parameter before `--` is treated as an attribute and any parameter after
`--` is treated as a pathname.
The change involves creating a new function `read_attr_from_blob`, which
given the path reads the blob for the path against the provided source and
parses the attributes line by line. This function is plugged into
`read_attr()` function wherein we go through the stack of attributes
files.

The null stream filter unsurprisingly does not look at its "filter"
argument, since it just eats bytes. But we can't drop it, since it has
to conform to the same virtual interface that real filters do. Mark the

As reported in [1] the "UNUSED(var)" macro introduced in
2174b8c75de (Merge branch 'jk/unused-annotation' into next,
2022-08-24) breaks coccinelle's parsing of our sources in files where
it occurs.
Let's instead partially go with the approach suggested in [2] of
making this not take an argument. As noted in [1] "coccinelle" will
ignore such tokens in argument lists that it doesn't know about, and
it's less of a surprise to syntax highlighters.
This undoes the "help us notice when a parameter marked as unused is
actually use" part of 9b240347543 (git-compat-util: add UNUSED macro,
2022-08-19), a subsequent commit will further tweak the macro to
implement a replacement for that functionality.

The start_async(), etc, functions need a "proc" callback that conforms
to a particular interface. Not every callback needs every parameter
(e.g., the caller might not even ask to open an input descriptor, in
which case there is no point in the callback looking at it). Let's mark
these for -Wunused-parameter.

The callback passed to git_config() must conform to a particular
interface. But most callbacks don't actually look at the extra "void
*data" parameter. Let's mark the unused parameters to make
-Wunused-parameter happy.
Note there's one unusual case here in get_remote_default() where we
actually ignore the "value" parameter. That's because it's only checking
whether the option is found at all, and not parsing its value.

The warning about converting line endings is extremely confusing. Its
two sentences each use the word "will" without specifying a timeframe,
which makes it sound like both sentences are referring to the same
timeframe. On top of that, it uses the term "original line endings"
without saying whether "original" means LF or CRLF.
Rephrase the warning to be clear about when the line endings will be
changed and what they will be changed to.
On a platform whose native line endings are not CRLF (e.g. Linux), the
"git add" step in the following sequence triggers the warning in
question:
$ git config core.autocrlf true
$ echo 'Hello world!' >hello.txt
$ git add hello.txt
warning: LF will be replaced by CRLF in hello.txt
The file will have its original line endings in your working directory

The clean/smudge conversion code path has been prepared to better
work on platforms where ulong is narrower than size_t.
* mc/clean-smudge-with-llp64:
clean/smudge: allow clean filters to process extremely large files
odb: guard against data loss checking out a huge file
git-compat-util: introduce more size_t helpers
odb: teach read_blob_entry to use size_t
t1051: introduce a smudge filter test for extremely large files
test-lib: add prerequisite for 64-bit platforms
test-tool genzeros: generate large amounts of data more efficiently
test-genzeros: allow more than 2G zeros in Windows
|
|
The filter system allows for alterations to file contents when they're
moved between the database and the worktree. We already made sure that
it is possible for smudge filters to produce contents that are larger
than `unsigned long` can represent (which matters on systems where
`unsigned long` is narrower than `size_t`, most notably 64-bit Windows).
Now we make sure that clean filters can _consume_ contents that are
larger than that.
Note that this commit only allows clean filters' _input_ to be larger
than can be represented by `unsigned long`.
This change makes only a very minute dent into the much larger project
to teach Git to use `size_t` instead of `unsigned long` wherever
appropriate.

Several methods specify that they take a 'struct index_state' pointer
with the 'const' qualifier because they intend to only query the data,
not change it. However, we will be introducing a step very low in the
method stack that might modify a sparse-index to become a full index in
the case that our queries venture inside a sparse-directory entry.
This change only removes the 'const' qualifiers that are necessary for
the following change which will actually modify the implementation of
index_name_stage_pos().

Create `enum conv_attrs_classification` to express the different ways

This will be used in a later commit when deciding whether to add a file

Separate the attribute gathering from the actual conversion by adding
_ca() variants of the conversion functions. These variants receive a
precomputed 'struct conv_attrs', not relying, thus, on an index state.
They will be used in a future patch adding parallel checkout support,
for two reasons:
- We will already load the conversion attributes in checkout_entry(),
before conversion, to decide whether a path is eligible for parallel
checkout. Therefore, it would be wasteful to load them again later,
for the actual conversion.
- The parallel workers will be responsible for reading, converting and
writing blobs to the working tree. They won't have access to the main
process' index state, so they cannot load the attributes. Instead,
they will receive the preloaded ones and call the _ca() variant of
the conversion functions. Furthermore, the attributes machinery is
optimized to handle paths in sequential order, so it's better to leave
it for the main process, anyway.

Update the calling sequence of `read_packetized_to_strbuf()` to take

only existing caller accordingly to explicitly pass the
formerly-assumed flags.
The `read_packetized_to_strbuf()` function calls `packet_read()` with

assumption has been fine for the single existing caller
`apply_multi_file_filter()` in `convert.c`.

Remove the `packet_flush_gently()` call in `write_packetized_from_buf() and

Rename both functions to `write_packetized_from_*_no_flush()` to prevent

`write_packetized_from_buf()` currently only has one caller:

The gitattributes documentation mentions that either the clean cmd or
the smudge cmd can be left unspecified in a filter definition. However,
when the filter is marked as 'required', the absence of any one of these
two should be treated as an error. Git already fails under these
circumstances, but not always in a pleasant way: omitting a clean cmd in
a required filter triggers an assertion error which leaves the user with
a quite verbose message:
git: convert.c:1459: convert_to_git_filter_fd: Assertion "ca.drv->clean || ca.drv->process" failed.
This assertion is not really necessary, as the apply_filter() call below
it already performs the same check. And when this condition is not met,
the function returns 0, making the caller die() with a much nicer
message. (Also note that die()-ing here is the right behavior as
`would_convert_to_git_filter_fd() == true` is a precondition to use
convert_to_git_filter_fd(), and the former is only true when the filter
is required.) So remove the assertion and add two regression tests to
make sure that git fails nicely when either the smudge or clean command
is missing on a required filter.

We return the length to a subset of a string using an "int *"
out-parameter. This is fine most of the time, as we'd expect config keys
to be relatively short, but it could behave oddly if we had a gigantic
config key. A more appropriate type is size_t.
Let's switch over, which lets our callers use size_t as appropriate
(they are bound by our type because they must pass the out-parameter as
a pointer). This is mostly just a cleanup to make it clear this code
handles long strings correctly. In practice, our config parser already
chokes on long key names (because of a similar int/size_t mixup!).
When doing an int/size_t conversion, we have to be careful that nobody
was trying to assign a negative value to the variable. I manually
confirmed that for each case here. They tend to just feed the result to
xmemdupz() or similar; in a few cases I adjusted the parameter types for
helper functions to make sure the size_t is preserved.

Now that we have the codebase wired up to pass any additional metadata
to filters, let's collect the additional metadata that we'd like to
pass.
The two main places we pass this metadata are checkouts and archives.
In these two situations, reading HEAD isn't a valid option, since HEAD
isn't updated for checkouts until after the working tree is written and
archives can accept an arbitrary tree. In other situations, HEAD will
usually reflect the refname of the branch in current use.
We pass a smaller amount of data in other cases, such as git cat-file,
where we can really only logically know about the blob.
This commit updates only the parts of the checkout code where we don't
use unpack_trees. That function and callers of it will be handled in a
future commit.
In the archive code, we leak a small amount of memory, since nothing we
pass in the archiver argument structure is freed.

There are a variety of situations where a filter process can make use of
some additional metadata. For example, some people find the ident
filter too limiting and would like to include the commit or the branch
in their smudged files. This information isn't available during
checkout as HEAD hasn't been updated at that point, and it wouldn't be
available in archives either.
Let's add a way to pass this metadata down to the filter. We pass the
blob we're operating on, the treeish (preferring the commit over the
tree if one exists), and the ref we're operating on. Note that we won't
pass this information in all cases, such as when renormalizing or when
we're performing diffs, since it doesn't make sense in those cases.
The data we currently get from the filter process looks like the
following:
command=smudge
pathname=git.c
0000
With this change, we'll get data more like this:
command=smudge
pathname=git.c
refname=refs/tags/v2.25.1
treeish=c522f061d551c9bb8684a7c3859b2ece4499b56b
blob=7be7ad34bd053884ec48923706e70c81719a8660
0000
There are a couple things to note about this approach. For operations
like checkout, treeish will always be a commit, since we cannot check
out individual trees, but for other operations, like archive, we can end
up operating on only a particular tree, so we'll provide only a tree as
the treeish. Similar comments apply for refname, since there are a
variety of cases in which we won't have a ref.
This commit wires up the code to print this information, but doesn't
pass any of it at this point. In a future commit, we'll have various
code paths pass the actual useful data down.

callees, which has been cleaned up (somewhat).

Allow hash_object_file() to work on arbitrary repos by introducing a
git_hash_algo parameter. Change callers which have a struct repository
pointer in their scope to pass on the git_hash_algo from the said repo.
For all other callers, pass on the_hash_algo, which was already being
used internally at hash_object_file(). This functionality will be used
in the following patch to make check_object_signature() be able to work
on arbitrary repos (which, in turn, will be used to fix an
inconsistency at object.c:parse_object()).

Code simplification.
* rs/skip-iprefix:
convert: use skip_iprefix() in validate_encoding()
utf8: use skip_iprefix() in same_utf_encoding()
|
|
Use skip_iprefix() to parse "UTF" case-insensitively instead of checking
with istarts_with(), building an upper-case version and then using
skip_prefix() on it. This gets rid of duplicate code and of a small
allocation.

The code to skip "UTF" and "UTF-" prefix, when computing an advice
message, did not work correctly when the prefix was "UTF", which
has been fixed.
* rs/convert-fix-utf-without-dash:
convert: fix handling of dashless UTF prefix in validate_encoding()
|
|
Strip "UTF" and an optional dash from the start of 'upper' without
passing a NULL pointer to skip_prefix() in the second call, as it cannot
handle that.

When applying multiple patches with git am, or when rebasing using the
am backend, it's possible that one of our patches has updated a
gitattributes file. Currently, we cache this information, so if a
file in a subsequent patch has attributes applied, the file will be
written out with the attributes in place as of the time we started the
rebase or am operation, not with the attributes applied by the previous
patch. This problem does not occur when using the -m or -i flags to
rebase.
To ensure we write the correct data into the working tree, expire the
cache after each patch that touches a path ending in ".gitattributes".
Since we load these attributes in multiple separate files, we must
expire them accordingly.
Verify that both the am and rebase code paths work correctly, including
the conflict marker size with am -3.

When the "clean" filter can reduce the size of a huge file in the
working tree down to a small "token" (a la Git LFS), there is no
point in allocating a huge scratch area upfront, but the buffer is
sized based on the original file size. The convert mechanism now
allocates very minimum and reallocates as it receives the output
from the clean filter process.
* jh/resize-convert-scratch-buffer:
convert: avoid malloc of original file size
|
|
We write the output of a "clean" filter into a strbuf. Rather than
growing the strbuf dynamically as we read its output, we make the
initial allocation as large as the original input file. This is a good
guess when the filter is just tweaking a few bytes, but it's disastrous
when the point of the filter is to condense a very large file into a
short identifier (e.g., the way git-lfs and git-annex do). We may ask to
allocate many gigabytes, causing the allocation to fail and Git to
die().
Instead, let's just let strbuf do its usual growth.
When the clean filter does output something around the same size as the
worktree file, the buffer will need to be reallocated until it fits,
starting at 8192 and doubling in size. Benchmarking indicates that
reallocation is not a significant overhead for outputs up to a
few MB in size.
