* lib/**.{h,c,gperf}: Use LGPLv2+ notice whenever the module description
says so.
|
| |
|
|
|
| |
* lib/realloc.c (_GL_USE_STDLIB_ALLOC): Do not define. This
module relies on GNU malloc. This fixes a test failure on AIX 7.1.

In glibc 2.30 and later, malloc, realloc and calloc reject
attempts to create objects larger than PTRDIFF_MAX bytes.
This patch changes malloc-gnu etc. to support this behavior
on non-GNU hosts. It also makes this change for malloc-posix etc.
since it’s a safety measure that ought to be in POSIX (perhaps
we can talk them into that...).
In writing this patch I found a complicated set of code that had
accumulated over the years, some written by yours truly. I got
rid of the code I couldn’t see the need for nowadays. Among other
things, the GNU realloc behavior is no longer incompatible with
the C standard, because in C17 the latter was relaxed to allow the
former. If I went too far in cleaning up, the old stuff can be
resurrected.
This change is mostly for 32-bit platforms, since practical 64-bit
platforms cannot create objects larger than PTRDIFF_MAX bytes anyway.
* doc/posix-functions/calloc.texi:
* doc/posix-functions/malloc.texi:
* doc/posix-functions/realloc.texi:
Mention ptrdiff_t issues, and go into more detail about what
the gnu extension module does.
* doc/posix-functions/realloc.texi: Fix now-obsolete commentary
about C99 vs glibc, as C17 allows the glibc behavior and POSIX
will follow suit when it gets around to it.
* lib/calloc.c, lib/malloc.c, lib/realloc.c:
Simplify by always supplying a GNU-compatible version,
as that suffices for correctness and is good enough for performance.
Include xalloc-oversized.h, and use xalloc_oversized to
check for ptrdiff_t overflow.
(NEED_CALLOC_GNU, NEED_MALLOC_GNU, NEED_REALLOC_GNU): Remove.
* m4/calloc.m4 (_AC_FUNC_CALLOC_IF):
* m4/malloc.m4 (_AC_FUNC_MALLOC_IF):
* m4/realloc.m4 (_AC_FUNC_REALLOC_IF):
Don’t start with a newline. Fix message to match behavior.
* m4/calloc.m4 (_AC_FUNC_CALLOC_IF): Don’t test for size_t overflow,
as the ptrdiff_t test is good enough.
* m4/calloc.m4 (gl_FUNC_CALLOC_GNU):
* m4/malloc.m4 (gl_FUNC_MALLOC_GNU):
* m4/realloc.m4 (gl_FUNC_REALLOC_GNU):
Do not define HAVE_CALLOC_GNU, HAVE_MALLOC_GNU, HAVE_REALLOC_GNU.
It’s not worth the aggravation of maintaining these, as they
are confusing (they don’t really mean GNU-compatible anyway).
Don’t bother testing for GNU behavior if we have already decided
to replace the function, since the replacement is always GNUish.
* m4/calloc.m4 (gl_FUNC_CALLOC_POSIX):
* m4/realloc.m4 (gl_FUNC_REALLOC_POSIX):
Defer to gl_FUNC_MALLOC_POSIX.
* m4/malloc.m4 (gl_FUNC_MALLOC_PTRDIFF, gl_CHECK_MALLOC_PTRDIFF):
New macros.
(gl_FUNC_MALLOC_POSIX): Use them to check for ptrdiff_t overflow.
* modules/calloc-gnu, modules/malloc-gnu, modules/realloc-gnu:
Remove no-longer-needed module indicators.
* modules/calloc-posix, modules/malloc-posix, modules/realloc-posix:
Depend on xalloc-oversized.
* modules/malloc-posix: Require gl_FUNC_MALLOC_POSIX instead of
calling it directly, so that other code can require it.
* modules/realloc-posix: Depend on free-posix and malloc-posix.

Suggested by Paul Eggert in
<https://lists.gnu.org/archive/html/bug-gnulib/2021-04/msg00119.html>.
* lib/malloc.c: Drop the code that intends to collaborate with
AC_FUNC_MALLOC.
* lib/realloc.c: Drop the code that intends to collaborate with
AC_FUNC_REALLOC.
* lib/calloc.c: Drop the code that intends to collaborate with the
nonexistent macro AC_FUNC_CALLOC.

* lib/realloc.c: #undef realloc if config.h defines it.
This fixes a typo that I introduced in
2011-04-08T18:39:01Z!eggert@cs.ucla.edu.
Apparently nobody uses Gnulib realloc in that way?

* modules/realloc-posix (configure.ac): Invoke gl_MODULE_INDICATOR.

Run "make update-copyright". Compare to commit 1602f0a from last year.

Run the new "make update-copyright" rule.

Use the same procedure as for 2009, outlined in

The files named by the following are exempted:
grep -v '^#' config/srclist.txt|grep -v '^$' \
| while read src dst; do
test -f "$dst" && { echo "$dst"; continue; }
test -d "$dst" || continue
echo "$dst"/$(basename "$src")
done > exempt
git ls-files tests/unictype >> exempt
In the remaining files, convert to all-interval notation if
- there is already at least one year interval like 2000-2003
- the file is maintained by me
- the file is in lib/uni*/, where that style already prevails
Otherwise, use update-copyright's default.
