      * src/alloc.c (allow_garbage_collection)

      Say that hashes are fixnums.
      (Fmake_hash_table): Say that that an integer rehash-size
      should be a fixnum.
      * doc/lispref/hash.texi (Defining Hash): Say that hash and
      comparison functions should be consistent and pure, and should

      pure_alloc returns cleared memory · 4a1507b8
      Paul Eggert authored
      * src/alloc.c (pure_alloc): Clear any heap-allocated storage.
      This is simpler than auditing all the callers to make sure
      they don’t assume pure memory is cleared memory, and the
      performance implication is nonexistent except when Emacs
      is misconfigured.  Also, add an assertion to catch
      caller misuse when pure space is exhausted.

      Fix expand-file-name for names starting with '~' · 8b13ec1d
      Ken Brown authored
      * src/fileio.c: (file_name_absolute_no_tilde_p):
      New static function.
      (Fexpand_file_name): If the current buffer's default-directory
      starts with "~user" where "user" is not a valid user name, don't
      give the '~' a special meaning.  Just treat the value of
      default-directory as a relative name.  (Bug#36502)
      * test/src/fileio-tests.el
      (fileio-tests--relative-default-directory): Add a test.

      Tweak recent hash-table fix · 49e80e76
      Paul Eggert authored
      * src/fns.c (maybe_resize_hash_table): Completely initialize the
      new ‘next’ vector before allocating more vectors, as this
      preserves locality a bit better and it’s safer not to leave an
      uninitialized Lisp object around.  Use next_size instead of
      new_size to compute new index size.

      Fix crash if user test munges hash table · 515afc9c
      Paul Eggert authored
      * src/fns.c (restore_mutability)
      (hash_table_user_defined_call): New functions.
      (cmpfn_user_defined, hashfn_user_defined): Use them.
      (make_hash_table, copy_hash_table):
      Mark new hash table as mutable.
      (check_mutable_hash_table): New function.
      (Fclrhash, Fputhash, Fremhash): Use it instead of CHECK_IMPURE.
      * src/lisp.h (struct hash_table_test): User-defined functions
      now take pointers to struct Lisp_Hash_Table, not to struct
      hash_table_test.  All uses changed.
      (struct Lisp_Hash_Table): New member ‘mutable’.
      * src/pdumper.c (dump_hash_table): Copy it.

      Simplify hashfn/cmpfn calling convention · b6f194a0
      Paul Eggert authored
      * src/fns.c (cmpfn_eql, cmpfn_equal, cmpfn_user_defined)
      (hashfn_eq, hashfn_equal, hashfn_eql, hashfn_user_defined):
      * src/profiler.c (cmpfn_profiler, hashfn_profiler):
      Use new calling convention where the return value is a fixnum
      instead of EMACS_UINT.  While we’re at it, put the hash table
      at the end, since that’s a bit simpler and generates better
      code (at least on the x86-64).  All callers changed.
      * src/fns.c (hash_lookup): Store fixnum rather than EMACS_UINT.
      All callers changed.
      (hash_put): Take a fixnum rather than an EMACS_UINT.
      All callers changed.  Remove unnecessary eassert (XUFIXNUM does it).
      * src/lisp.h (struct hash_table_test):
      Adjust signatures of cmpfn and hashfn.

      Inhibit GC after inhibit_garbage_collection · 5018b663
      Paul Eggert authored
      Without this patch, there are unlikely ways that garbage
      collection could occur (sometimes causing undefined behavior)
      even when inhibit_garbage_collection is in effect.
      * src/alloc.c (garbage_collection_inhibited): New var.
      (pure_alloc): Increment it if pure space is exhausted, so that
      garbage_collect_1 no longer needs to inspect
      (allow_garbage_collection): New function.
      (inhibit_garbage_collection): Increment the new variable rather
      than specbinding a user variable.
      (garbage_collect_1): Do not garbage collect if the new variable
      is set, rather than if pure_bytes_used_before_overflow is set.

      Simplify maybe_gc implementation · 26de2d42
      Paul Eggert authored
      * src/alloc.c (consing_until_gc): New variable, replacing the
      combination of consing_since_gc and gc_relative_threshold.
      All uses changed.
      (byte_ct): Move decl here from lisp.h.
      (memory_full_cons_threshold): New an enum constant.
      (free_cons): Check for integer overflow in
      statistics calculation.
      * src/lisp.h (object_ct): Move decl here from alloc.c.
      (OBJECT_CT_MAX): New macro.
      (maybe_gc): Simplify accordingly.

      Rename ‘pure’ to ‘purecopy’ · df5024db
      Paul Eggert authored
      * src/lisp.h (struct Lisp_Hash_Table): Rename ‘pure’ member to
      ‘purecopy’, as the old name was quite confusing (it did not
      mean the hash table was pure).  All uses changed.

      Fix hash table overallocation etc. · b0908a0f
      Paul Eggert authored
      * src/fns.c (set_hash_key_and_value, set_hash_next)
      (set_hash_hash, set_hash_index): Remove.  All uses removed.
      (maybe_resize_hash_table): Don’t update h->next until it’s
      known that all the allocations succeeded, to avoid trashing
      the hash table if memory is exhausted.  Don’t overallocate the
      other vectors.  Don’t output growth message if the hash table
      didn’t actually grow due to allocation failure.  Assume C99
      decls after statements.
