alloc_nr, ALLOC_GROW, and ALLOC_GROW_BY are commonly used macros for
dynamic array allocation. Moving these macros to git-compat-util.h with
the other alloc macros focuses alloc.[ch] to allocation for Git objects
and additionally allows us to remove inclusions to alloc.h from files
that solely used the above macros.

Earlier, 47cfc9bd (attr: add flag `--source` to work with tree-ish,
2023-01-14) taught "git check-attr" the "--source=<tree>" option to
allow it to read attribute files from a tree-ish, but did so only
for the command. Just like "check-attr" users wanted a way to use
attributes from a tree-ish and not from the working tree files,
users of other commands (like "git diff") would benefit from the
same.
Undo most of the UI change the commit made, while keeping the
internal logic to read attributes from a given tree-ish. Expose the
internal logic via a new "--attr-source=<tree>" command line option
given to "git", so that it can be used with any git command that
runs as part of the main git process.
Additionally, add an environment variable GIT_ATTR_SOURCE that is set
when --attr-source is passed in, so that subprocesses use the same value
for the attributes source tree.

The userdiff regexp patterns for various filetypes that are built
into the system have been updated to avoid triggering regexp errors
from UTF-8 aware regex engines.
* rs/userdiff-multibyte-regex:
userdiff: support regexec(3) with multi-byte support
|
|
Since 1819ad327b (grep: fix multibyte regex handling under macOS,
2022-08-26) we use the system library for all regular expression
matching on macOS, not just for git grep. It supports multi-byte
strings and rejects invalid multi-byte characters.
This broke all built-in userdiff word regexes in UTF-8 locales because
they all include such invalid bytes in expressions that are intended to
match multi-byte characters without explicit support for that from the
regex engine.
"|[^[:space:]]|[\xc0-\xff][\x80-\xbf]+" is added to all built-in word
regexes to match a single non-space or multi-byte character. The \xNN
characters are invalid if interpreted as UTF-8 because they have their
high bit set, which indicates they are part of a multi-byte character,
but they are surrounded by single-byte characters.
Replace that expression with "|[^[:space:]]" if the regex engine
supports multi-byte matching, as there is no need to have an explicit
range for multi-byte characters then. Check for that capability at
runtime, because it depends on the locale and thus on environment
variables. Construct the full replacement expression at build time
and just switch it in if necessary to avoid string manipulation and
allocations at runtime.
Additionally the word regex for tex contains the expression
"[a-zA-Z0-9\x80-\xff]+" with a similarly invalid range. The best
replacement with only valid characters that I can come up with is
"([a-zA-Z0-9]|[^\x01-\x7f])+". Unlike the original it matches NUL
characters, though. Assuming that tex files usually don't contain NUL
this should be acceptable.

It can be useful to specify diff algorithms per file type. For example,
one may want to use the minimal diff algorithm for .json files, another
for .c files, etc.
The diff machinery already checks attributes for a diff driver. Teach
the diff driver parser a new type "algorithm" to look for in the
config, which will be used if a driver has been specified through the
attributes.
Enforce precedence of the diff algorithm by favoring the command line
option, then looking at the driver attributes & config combination, then
finally the diff.algorithm config.
To enforce precedence order, use a new `ignore_driver_algorithm` member
during options parsing to indicate the diff algorithm was set via command
line args.

A new kind of class was added in Java 17 -- sealed classes.[1] This
feature includes several new keywords that may appear in a declaration
of a class. New modifiers before name of the class: "sealed" and
"non-sealed", and a clause after name of the class marked by keyword
"permits".
The current set of regular expressions in userdiff.c already allows the
modifier "sealed" and the "permits" clause, but not the modifier
"non-sealed", which is the first hyphenated keyword in Java.[2] Allow
hyphen in the words that precede the name of type to match the
"non-sealed" modifier.
In new input file "java-sealed" for the test t4018-diff-funcname.sh, use
a Java code comment for the marker "RIGHT". This workaround is needed,
because the name of the sealed class appears on the line of code that
has the "ChangeMe" marker.

A new kind of class was added in Java 16 -- records.[1] The syntax of
records is similar to regular classes with one important distinction:
the name of the record class is followed by a mandatory list of
components. The list is enclosed in parentheses, it may be empty, and
it may immediately follow the name of the class or type parameters, if
any, with or without separating whitespace. For example:
public record Example(int i, String s) {
}
public record WithTypeParameters<A, B>(A a, B b, String s) {
}
record SpaceBeforeComponents (String comp1, int comp2) {
}
Support records in the builtin userdiff pattern for Java. Add "record"
to the alternatives of keywords for kinds of class.
Allowing matching various possibilities for the type parameters and/or
list of the components of a record has already been covered by the
preceding patch.

A class or interface in Java can have type parameters following the name
in the declared type, surrounded by angle brackets (paired less than and
greater than signs).[2] The type parameters -- `A` and `B` in the
examples -- may follow the class name immediately:
public class ParameterizedClass<A, B> {
}
or may be separated by whitespace:
public class SpaceBeforeTypeParameters <A, B> {
}
A part of the builtin userdiff pattern for Java matches declarations of
classes, enums, and interfaces. The regular expression requires at
least one whitespace character after the name of the declared type.
This disallows matching for opening angle bracket of type parameters
immediately after the name of the type. Mandatory whitespace after the
name of the type also disallows using the pattern in repositories with a
fairly common code style that puts braces for the body of a class on
separate lines:
class WithLineBreakBeforeOpeningBrace
{
}
Support matching Java code in more diverse code styles and declarations
of classes and interfaces with type parameters immediately following the
name of the type in the builtin userdiff pattern for Java. Do so by
just matching anything until the end of the line after the keywords for
the kind of type being declared.

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 implementation of digit-separating single-quotes introduced a
note-worthy regression: the change of a character literal with a
digit would splice the digit and the closing single-quote. For
example, the change from 'a' to '2' is now tokenized as
'[-a'-]{+2'+} instead of '[-a-]{+2+}'.
The options to fix the regression are:
- Tighten the regular expression such that the single-quote can only
occur between digits (that would match the official syntax).
- Remove support for digit separators.
I chose to remove support, because
- I have not seen a lot of code make use of digit separators.
- If code does use digit separators, then the numbers are typically
long. If a change in one of the segments occurs, it is actually
better visible if only that segment is highlighted as the word
that changed instead of the whole long number.
This choice does introduce another minor regression, though, which
is highlighted in the test case: when a change occurs in the second
or later segment of a hexadecimal number where the segment begins
with a digit, but also has letters, the segment is mistaken as
consisting of a number and an identifier. I can live with that.

Generally, word regex can be written such that they match tokens
liberally and need not model the actual syntax because it can be assumed
that the regex will only be applied to syntactically correct text.
The regex for cpp (C/C++) is too liberal, though. It regards these
sequences as single tokens:
1+2
1.5-e+2+f
and the following amalgams as one token:
.l as in str.length
.f as in str.find
.e as in str.erase
Tighten the regex in the following way:
- Accept + and - only in one position in the exponent. + and - are no
longer regarded as the sign of a number and are treated by the
catcher-all that is not visible in the driver's regex.
- Accept a leading decimal point only when it is followed by a digit.
For readability, factor hex- and binary numbers into an own term.
As a drive-by, this fixes that floating point numbers such as 12E5
(with upper-case E) were split into two tokens.

Add a diff driver for Scheme-like languages which recognizes top level
and local `define` forms, whether it is a function definition, binding,
syntax definition or a user-defined `define-xyzzy` form.
Also supports R6RS `library` forms, `module` forms along with class and
struct declarations used in Racket (PLT Scheme).
Alternate "def" syntax such as those in Gerbil Scheme are also
supported, like defstruct, defsyntax and so on.
The rationale for picking `define` forms for the hunk headers is because
it is usually the only significant form for defining the structure of
the program, and it is a common pattern for schemers to have local
function definitions to hide their visibility, so it is not only the top
level `define`'s that are of interest. Schemers also extend the language
with macros to provide their own define forms (for example, something
like a `define-test-suite`) which is also captured in the hunk header.
Since it is common practice to extend syntax with variants of a form
like `module+`, `class*` etc, those have been supported as well.
The word regex is a best-effort attempt to conform to R7RS[1] valid
identifiers, symbols and numbers.

The third part of the Fortran xfuncname regex wants to match the
beginning of a subroutine or function, so it allows for all characters
except `'`, `"` or whitespace before the keyword 'function' or
'subroutine'. This is meant to match the 'recursive', 'elemental' or
'pure' keywords, as well as function return types, and to prevent
matches inside strings.
However, the negated set does not contain the `!` comment character,
so a line with an end-of-line comment containing the keyword 'function' or
'subroutine' followed by another word is mistakenly chosen as a hunk header.
Improve the regex by adding `!` to the negated set.

It's typical to find Markdown documentation alongside source code, and
having better context for documentation changes is useful; see also

The pattern is based on the CommonMark specification 0.29, section 4.2
<https://spec.commonmark.org/> but doesn't match empty headings, as
seeing them in a hunk header is unlikely to be useful.
Only ATX headings are supported, as detecting setext headings would
require printing the line before a pattern matches, or matching a
multiline pattern. The word-diff pattern is the same as the pattern for

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.

* ln/userdiff-elixir:
userdiff: remove empty subexpression from elixir regex
|
|
The regex failed to compile on FreeBSD.
Also add /* -- */ mark to separate the two regex entries given to
the PATTERNS() macro, to make it consistent with patterns for other
content types.

The userdiff machinery has been taught that "async def" is another
way to begin a "function" in Python.
* jh/userdiff-python-async:
userdiff: support Python async functions
|
|
Python's async functions (declared with "async def" rather than "def")
were not being displayed in hunk headers. This commit teaches git about
the async function syntax, and adds tests for the Python userdiff regex.
