a002cbb9	2021-02-05T17:08:45	regex: fix comment location * lib/regexec.c (update_regs): Move comment.
e3a06e1c	2021-02-05T17:08:39	regex-tests: add bug 11053 test * tests/test-regex.c (main): New test case for glibc bug 11053.
70b673eb	2021-02-05T17:08:10	regex: fix longstanding backref match bug This fixes a longstanding glibc bug concerning backreferences <https://sourceware.org/11053> (2009-12-04). * lib/regexec.c (proceed_next_node, push_fail_stack) (pop_fail_stack): Push and pop the previous registers as well as the current ones. All callers changed. (set_regs): Also pop if CUR_NODE has already been checked, so that it does not get added as a duplicate set entry. (update_regs): Fix comment location. * tests/test-regex.c (tests): New constant. (bug_regex11): New test function. (main): Bump alarm value. Call new test function.
f5596242	2021-02-05T16:35:46	regex: avoid duplicate in espilon closure * lib/regcomp.c (calc_eclosure_iter): Insert NODE into epsilon closure first rather than last. Otherwise, the epsilon closure might contain a duplicate of NODE.
7256c713	2021-02-05T17:08:29	regex: debug check for set member duplicates * lib/regex_internal.c (re_node_set_insert): Add a DEBUG_ASSERT that would have caught some recently-fixed performance bugs that caused sets to contain duplicate members.
d6f9ba54	2021-02-05T16:35:45	regex: minor refactoring * lib/regexec.c (proceed_next_node): Use more-local decls.
37f2bbbe	2021-02-05T16:35:45	regex: avoid undefined behavior * lib/regexec.c (pop_fail_stack): If the stack is empty, return -1 instead of indulging in undefined behavior. This simplifies callers, and avoids undefined behavior in some cases (see glibc bug 11053, though this change does not fix that overall bug).
a588d480	2021-02-05T16:35:46	regex-tests: fix typo * tests/test-regex.c (main): Fix typo that would have caused an old test case to report incorrect values on failure.
388d9432	2021-02-05T16:35:46	regex: make it easier to merge into glibc * lib/regex_internal.h [_LIBC]: Do not include Gnulib’s dynarray.h.

5c52f00c	2021-01-19T18:35:30	fnmatch, regex, fts: FALLTHROUGH consistency Be more consistent about how FALLTHROUGH is defined. For Gnulib, use attribute.h. For glibc, use __GNUC__ >= 7.

b0ebaf83	2021-01-08T17:54:30	tempname: don’t block for minutes Derived from a patch proposed by Adhemerval Zanella in: https://sourceware.org/pipermail/libc-alpha/2021-January/121302.html * lib/tempname.c (random_bits): Use GRND_NONBLOCK.

1731fef3	2021-01-08T14:22:15	regexec: remove alloca usage in build_trtable Prompted by this different change proposed by Adhemerval Zanella: https://sourceware.org/pipermail/libc-alpha/2021-January/121373.html * lib/regexec.c (build_trtable): Prevent inlining, so that it doesn’t bloat the caller’s stack. Use auto variables instead of alloca/malloc. After these changes, build_trtable’s total stack allocation is only 20 KiB on a 64-bit machine, and this is less than glibc’s 64 KiB cutoff so there’s little point to using alloca to shrink it. Although Gnulib traditionally has used a 4 KiB cutoff, going to 20 KiB here should not be a significant problem in practice; Gnulib-using packages concerned about overflow of tiny stacks can compile with something like gcc -fstack-clash-protection. * config/srclist.txt: Comment out regexec.c for now.
b0e441b8	2021-01-08T12:01:37	scratch_buffer: add scratch_buffer_dupfree macro * lib/scratch_buffer.h (__libc_scratch_buffer_dupfree): New macro, needed to support recent changes in this module.
b6207ab3	2021-01-08T12:00:09	regex: remove alloca usage on regex set_regs Derived from this patch by Adhemerval Zanella: https://sourceware.org/pipermail/libc-alpha/2021-January/121372.html * lib/regex_internal.h: Include dynarray.h, for Gnulib. * lib/regexec.c (DYNARRAY_STRUCT, DYNARRAY_ELEMENT) (DYNARRAY_PREFIX): New macros. Include malloc/dynarray-skeleton.c. (set_regs): Use dynarray rather than alloca. * modules/regex (Depends-on): Add dynarray.
921d2ea1	2021-01-08T11:44:19	dynarray: new module * config/srclist.txt: Mention the new files. * lib/cdefs.h (__attribute_maybe_unused__): New macro, like Gnulib’s _GL_ATTRIBUTE_MAYBE_UNUSED but with glibc naming conventions. * lib/libc-config.h: Use it instead of __glibc_likely. * lib/dynarray.h, modules/dynarray: New files. * lib/malloc/dynarray-skeleton.c, lib/malloc/dynarray.h: * lib/malloc/dynarray_at_failure.c: * lib/malloc/dynarray_emplace_enlarge.c: * lib/malloc/dynarray_finalize.c, lib/malloc/dynarray_resize.c: * lib/malloc/dynarray_resize_clear.c, modules/dynarray: New files, from glibc with the following changes needed for portability to compilers that are not recent-enough GCC. * lib/malloc/dynarray_at_failure.c: Include stdlib.h, for abort. (__libc_dynarray_at_failure) [!_LIBC]: Simply abort. * lib/malloc/dynarray_emplace_enlarge.c: * lib/malloc/dynarray_resize.c: Include intprops.h, and use INT_MULTIPLY_WRAPV instead of __builtin_mul_overflow. * lib/malloc/dynarray.h (__libc_dynarray_at_failure): Use _Noreturn instead of __attribute__ ((noreturn)). * lib/malloc/dynarray_resize_clear.c: Do not include stdlib.h; it’s not needed. (__libc_dynarray_resize_clear): Do not do arithmetic on void . lib/malloc/dynarray-skeleton.c (struct DYNARRAY_STRUCT): Do not use anonymous unions, as they are not in C99. All uses changed. Use __nonnull (X) instead of __attribute__ ((nonnull X)), and __attribute_maybe_unused__ instead of __attribute__ ((unused)).
bdae9a5d	2021-01-08T11:49:59	bootstrap: Fix parsing of package name. * build-aux/bootstrap (package): Attempt to use autoconf --trace to parse AC_INIT before falling back to sed expression.

There is no need in glibc or Gnulib to distinguish clang from other compilers here, so be consistent and use the simpler names. * lib/cdefs.h (__glibc_has_builtin, __glibc_has_extension): Rename from __glibc_clang_has_builtin, __glibc_clang_has_extension. All uses changed. (__glibc_clang_has_attribute): Remove. All uses replaced by __glibc_has_attribute. * lib/libc-config.h [!__glibc_likely]: Undef them here too.

regexec: remove alloca usage in build_trtable Prompted by this different change proposed by Adhemerval Zanella: https://sourceware.org/pipermail/libc-alpha/2021-January/121373.html * lib/regexec.c (build_trtable): Prevent inlining, so that it doesn’t bloat the caller’s stack. Use auto variables instead of alloca/malloc. After these changes, build_trtable’s total stack allocation is only 20 KiB on a 64-bit machine, and this is less than glibc’s 64 KiB cutoff so there’s little point to using alloca to shrink it. Although Gnulib traditionally has used a 4 KiB cutoff, going to 20 KiB here should not be a significant problem in practice; Gnulib-using packages concerned about overflow of tiny stacks can compile with something like gcc -fstack-clash-protection. * config/srclist.txt: Comment out regexec.c for now.

(__libc_dynarray_at_failure) [!_LIBC]: Simply abort. * lib/malloc/dynarray_emplace_enlarge.c: * lib/malloc/dynarray_resize.c: Include intprops.h, and use INT_MULTIPLY_WRAPV instead of __builtin_mul_overflow. * lib/malloc/dynarray.h (__libc_dynarray_at_failure): Use _Noreturn instead of __attribute__ ((noreturn)). * lib/malloc/dynarray_resize_clear.c: Do not include stdlib.h; it’s not needed.
