When using `IFTODT` defined in libc, `dirent.d_type` oriented pathtype
is compatible with `IFTODT(stat.st_mode)`. However they are not
compatible when emulating `IFTODT`, so `glob_helper` has to stat instead
of reusing dirent result by passing unknown pathtype to `glob_helper`.
This is a follow-up fix of 0c90ca4dd0
dir.c defines IFTODT if the system doesn't have it. The macro is used
when comparing with rb_pathtype_t's cases. rb_pathtype_t's cases are
defined by DT_XXX macro if they are available, or defined using IFTODT.
Most POSIX-compatible platforms have both IFTODT and DT_XXX and most of
other platforms like MinGW have neither of them. On those platforms,
DT_XXX-oriented rb_pathtype_t is always compared with values converted
by system's IFTODT, and emulated-IFTODT-oriented rb_pathtype_t is always
compared with values converted by emulated-IFTODT.
However, when IFTODT is *not defined* and DT_XXX is *defined*, like
on wasi-libc, DT_XXX-oriented rb_pathtype_t was compared with values
converted by emulated-IFTODT, and they are not guaranteed to be
compatible.
This patch fixes such a situation by using emulated-IFTODT to define
rb_pathtype_t when either IFTODT or DT_XXX is not available.
This was already documented as being ignored, but it wasn't being
ignored, causing an issue in a particular case where a UTF-8
pattern was provided and a filename was tested that wasn't valid
UTF-8.
Fixes [Bug #14456]
The documentation already stated this was an error in one case
(when it was previously a warning). Describe the other case,
where chdir without block is called inside block passed to chdir.
Fixes [Bug #15661]
RARRAY_AREF has been a macro for reasons. We might not be able to
change that for public APIs, but why not relax the situation internally
to make it an inline function.
Sort the results which matched single wildcard or character set in
binary ascending order, unless `sort: false` is given. The order
of an Array of pattern strings and braces are not affected.
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
This removes the related tests, and puts the related specs behind
version guards. This affects all code in lib, including some
libraries that may want to support older versions of Ruby.
This removes the security features added by $SAFE = 1, and warns for access
or modification of $SAFE from Ruby-level, as well as warning when calling
all public C functions related to $SAFE.
This modifies some internal functions that took a safe level argument
to no longer take the argument.
rb_require_safe now warns, rb_require_string has been added as a
version that takes a VALUE and does not warn.
One public C function that still takes a safe level argument and that
this doesn't warn for is rb_eval_cmd. We may want to consider
adding an alternative method that does not take a safe level argument,
and warn for rb_eval_cmd.
This changeset basically replaces `ruby_xmalloc(x * y)` into
`ruby_xmalloc2(x, y)`. Some convenient functions are also
provided for instance `rb_xmalloc_mul_add(x, y, z)` which allocates
x * y + z byes.
Cfuncs that use rb_scan_args with the : entry suffer similar keyword
argument separation issues that Ruby methods suffer if the cfuncs
accept optional or variable arguments.
This makes the following changes to : handling.
* Treats as **kw, prompting keyword argument separation warnings
if called with a positional hash.
* Do not look for an option hash if empty keywords are provided.
For backwards compatibility, treat an empty keyword splat as a empty
mandatory positional hash argument, but emit a a warning, as this
behavior will be removed in Ruby 3. The argument number check
needs to be moved lower so it can correctly handle an empty
positional argument being added.
* If the last argument is nil and it is necessary to treat it as an option
hash in order to make sure all arguments are processed, continue to
treat the last argument as the option hash. Emit a warning in this case,
as this behavior will be removed in Ruby 3.
* If splitting the keyword hash into two hashes, issue a warning, as we
will not be splitting hashes in Ruby 3.
* If the keyword argument is required to fill a mandatory positional
argument, continue to do so, but emit a warning as this behavior will
be going away in Ruby 3.
* If keyword arguments are provided and the last argument is not a hash,
that indicates something wrong. This can happen if a cfunc is calling
rb_scan_args multiple times, and providing arguments that were not
passed to it from Ruby. Callers need to switch to the new
rb_scan_args_kw function, which allows passing of whether keywords
were provided.
This commit fixes all warnings caused by the changes above.
It switches some function calls to *_kw versions with appropriate
kw_splat flags. If delegating arguments, RB_PASS_CALLED_KEYWORDS
is used. If creating new arguments, RB_PASS_KEYWORDS is used if
the last argument is a hash to be treated as keywords.
In open_key_args in io.c, use rb_scan_args_kw.
In this case, the arguments provided come from another C
function, not Ruby. The last argument may or may not be a hash,
so we can't set keyword argument mode. However, if it is a
hash, we don't want to warn when treating it as keywords.
In Ruby files, make sure to appropriately use keyword splats
or literal keywords when calling Cfuncs that now issue keyword
argument separation warnings through rb_scan_args. Also, make
sure not to pass nil in place of an option hash.
Work around Kernel#warn warnings due to problems in the Rubygems
override of the method. There is an open pull request to fix
these issues in Rubygems, but part of the Rubygems tests for
their override fail on ruby-head due to rb_scan_args not
recognizing empty keyword splats, which this commit fixes.
Implementation wise, adding rb_scan_args_kw is kind of a pain,
because rb_scan_args takes a variable number of arguments.
In order to not duplicate all the code, the function internals need
to be split into two functions taking a va_list, and to avoid passing
in a ton of arguments, a single struct argument is used to handle
the variables previously local to the function.
