Only dump the actual data, and the test encoded as an enum. This
simplifies dumping, makes dump files smaller and saves space at run
time.
* src/lisp.h (hash_table_std_test_t): New enum.
(struct Lisp_Hash_Table): Add frozen_test member, consuming no extra space.
* src/fns.c (hashfn_user_defined): Now static.
(hash_table_test_from_std): New.
(hash_table_rehash): Rename to...
(hash_table_thaw): ...this and rewrite.
* src/pdumper.c (hash_table_contents): Only include actual data, not
unused space.
(hash_table_std_test): New.
(hash_table_freeze): Set frozen_test from test.
(dump_hash_table): Dump frozen_test, not the whole test struct.
Don't bother other dumping fields that can be derived.
These parameters have no visible semantics and are hardly ever used,
so just use the default values for all hash tables. This saves
memory, shrinks the external representation, and will improve
performance.
* src/fns.c (std_rehash_size, std_rehash_threshold): New.
(hash_index_size): Use std_rehash_threshold. Remove table argument.
All callers updated.
(make_hash_table): Remove rehash_size and rehash_threshold args.
All callers updated.
(maybe_resize_hash_table)
(Fhash_table_rehash_size, Fhash_table_rehash_threshold):
Use std_rehash_size and std_rehash_threshold.
(Fmake_hash_table): Ignore :rehash-size and :rehash-threshold args.
* src/lisp.h (struct Lisp_Hash_Table):
Remove rehash_size and rehash_threshold fields.
(DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE): Remove.
* src/lread.c (hash_table_from_plist): Don't read rehash-size or
rehash-threshold.
(syms_of_lread): Remove unused symbols.
* src/print.c (print_object): Don't print rehash-size or rehash-threshold.
* src/pdumper.c (dump_hash_table): Don't dump removed fields.
This takes less space (saves an entire word) and is more type-safe.
No change in behaviour.
* src/lisp.h (hash_table_weakness_t): New.
(struct Lisp_Hash_Table): Replace Lisp object `weak` with enum
`weakness`.
* src/fns.c
(keep_entry_p, hash_table_weakness_symbol): New.
(make_hash_table): Retype argument. All callers updated.
(sweep_weak_table, Fmake_hash_table, Fhash_table_weakness):
* src/alloc.c (purecopy_hash_table, purecopy, process_mark_stack):
* src/pdumper.c (dump_hash_table):
* src/print.c (print_object): Use retyped field.
It's not a meaningful part of the external representation.
This allows for faster printing and reading, smaller
external representation, and less memory consumption.
* src/print.c (print_object): Omit size.
* src/lread.c (hash_table_from_plist): Take size from the data.

Qunbound is used for many things; using a predicate and constant for

The profiler stored data being collected in Lisp hash tables but
relied heavily on their exact internal representation, which made it
difficult and error-prone to change the hash table implementation.
In particular, the profiler has special run-time requirements that are
not easily met using standard Lisp data structures: accesses and
updates are made from async signal handlers in almost any messy
context you can think of and are therefore very constrained in what
they can do.
The new profiler tables are designed specifically for their purpose
and are more efficient and, by not being coupled to Lisp hash tables,
easier to keep safe.
The old profiler morphed internal hash tables to ones usable from Lisp
and thereby made them impossible to use internally; now export_log
just makes new hash table objects for Lisp. The Lisp part of the
profiler remains entirely unchanged.
* src/alloc.c (garbage_collect): Mark profiler tables.
* src/eval.c (get_backtrace): Fill an array of Lisp values instead of
a Lisp vector.
* src/profiler.c (log_t): No longer a Lisp hash table but a custom
data structure: a fully associative fixed-sized cache that maps
fixed-size arrays of Lisp objects to counts.
(make_log): Build new struct.
(mark_log, free_log, get_log_count, set_log_count, get_key_vector)
(log_hash_index, remove_log_entry, trace_equal, trace_hash)
(make_profiler_log, free_profiler_log, mark_profiler): New.
(cmpfn_profiler, hashtest_profiler, hashfn_profiler)
(syms_of_profiler_for_pdumper): Remove.
(approximate_median, evict_lower_half, record_backtrace, export_log)
(Fprofiler_cpu_log, Fprofiler_memory_log, syms_of_profiler):
Adapt to the new data structure.
These are useful for measuring hashing and collisions.
* src/fns.c (Finternal__hash_table_histogram)
(Finternal__hash_table_buckets, Finternal__hash_table_index_size):
New.
* lisp/progmodes/sh-script.el (sh-font-lock-paren): Also recognize
`FOO)` after `{`.
(sh-smie-sh-rules): Make `for` rule apply to `case FOO { ...}` as well.
* test/manual/indent/shell.sh: Add new test case.
* lisp/progmodes/lua-ts-mode.el (lua-ts--simple-indent-rules):
Add a rule to indent multi-line assignments and if statements.
(lua-ts-indent-continuation-lines): New user option.
* test/lisp/progmodes/lua-ts-mode-resources/indent.erts: Add
tests. (Bug#68279)
This fixes bug#68200.
* lisp/emacs-lisp/bytecomp.el (byte-compile-output-docform):
Note that let-binding a buffer local variable leaves it buffer
local, hence to transfer the binding of
byte-compile-dynamic-docstrings to the output buffer, an
intermediate variable is needed. Implement this.
* lisp/auth-source.el (auth-source-macos-keychain-search):
Support numeric port numbers (bug#68376).
(auth-source-macos-keychain-search-items): Make regexp more robust.
* test/lisp/auth-source-tests.el (test-macos-keychain-search):
Extend test.
It looks like there are actually three kinds of no-op functions.
* doc/lispref/functions.texi (Calling Functions): Fix count and
plural of no-op functions.
