* Alternative implementation for weak hash tablesHelmut Eller2026-02-021-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It can be enabled with -DUSE_EPHEMERON_POOL. This variant uses the ephemeron pool and hence sovles the key-in-value problem. This version stores key/values pairs a vector-of-pairs instead of a pair-of-vectors. The same vector-of-pairs type is used for weak and non-weak. This avoids the code duplication used by the pair-of-vector version; though it adds a bit of overhead to the non-weak code path. * src/lisp.h: (struct vector_pair [!USE_EPHEMERON_POOL]): New type. (struct pair_vector [USE_EPHEMERON_POOL]):New type. (hash_table_kv): New typedef used to both version. (hash_table_kv_create, hash_table_kv_free, hash_table_kv_key) (hash_table_kv_value, hash_table_kv_set_key, hash_table_kv_set_value) (hash_table_kv_null): New helpers (struct Lisp_Hash_Table): Use a single field kv of type hash_table_kv instead of two fields.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The info returned from `garbage-collect` is really handy to track the evolution of the heap size, but sadly it's available only at the cost of running a full GC, which has two big downsides: it's slow, it affects what we're measuring, and it can't be used in `post-gc-hook`. So, this patch makes it available without running the GC. * src/alloc.c (Fgarbage_collect_heapsize): New function, extracted from `Fgarbage_collect`. (Fgarbage_collect): Use it. (syms_of_alloc): defsubr it. * doc/lispref/internals.texi (Garbage Collection): Extract documentation for it from that of `garbage-collect`.

| * Include malloc.h early in alloc.cPaul Eggert2025-12-071-4/+4
| | | | | | | | | | | | | | | | | | | | | | * src/alloc.c, src/gmalloc.c: Include <malloc.h> before <stdlib.h>. This mimics include patterns elsewhere, and avoids a problem if malloc.h declares realloc (i.e., rpl_realloc) early as extern, whereas Gnulib stdlib.h declares it later as inline which means it is extern inline, which clashes with gmalloc’s definition of rpl_realloc when gmalloc.o is used. Problem discovered when building Emacs on Ubuntu 25.10 with "./configure CC='gcc -m32' emacs_cv_struct_alignment=no gl_cv_header_working_stdalign_h=no".

The primary difficulty was the changed return type of the bignum_val function. The idiom "*bignum_val (foo)" was used all over the place. For the flat representation, it seems impossible to define bignum_val such that it returns a pointer. I changed the return type to a struct, but that made it necessary to change the idiom to "bignum_val (foo).z". * src/bignum.h (FLAT_BIGNUMS): Define if HAVE_MPS. (struct Lisp_Bignums): Define alternative representation. (struct bignum_val): New helper struct. (bignum_val): Change return type and define different version for flat bignums.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only allow string mutation that is certain not to require string data to be resized and reallocated: writing bytes into a unibyte string, and changing ASCII to ASCII in a multibyte string. This ensures that mutation will never transform a unibyte string to multibyte, that the size of a string in bytes never changes, and that the byte offsets of characters remain the same. Most importantly, it removes a long-standing obstacle to reform of string representation and allow for future performance improvements. * src/data.c (Faset): Disallow resizing string mutation. * src/fns.c (clear_string_char_byte_cache): * src/alloc.c (resize_string_data): Remove. * test/src/data-tests.el (data-aset-string): New test. * test/lisp/subr-tests.el (subr--subst-char-in-string): Skip error cases. * test/src/alloc-tests.el (aset-nbytes-change): Remove test that is no longer relevant. * doc/lispref/strings.texi (Modifying Strings): * doc/lispref/sequences.texi (Array Functions): * doc/lispref/text.texi (Substitution): Update manual. * etc/NEWS: Announce.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The compile-time option XMALLOC_BLOCK_INPUT_CHECK was added in 2012 (commit 4d7e6e51dd4acecff) to allow blocking input during malloc-family calls, in case any issues arose from related changes in Emacs 24.3. However, it has not been referenced on emacs-devel or the bug tracker in over a decade. It is clear that we do not need it, as our signal handlers do not allocate memory. Removing it simplifies the allocation function wrappers and eliminates dead debug code.
