* Use a dedicated type to represent interpreted-function valuesStefan Monnier2024-04-281-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change `function` so that when evaluating #'(lambda ...) we return an object of type `interpreted-function` rather than a list starting with one of `lambda` or `closure`. The new type reuses the existing PVEC_CLOSURE (nee PVEC_COMPILED) tag and tries to align the corresponding elements: - the arglist, the docstring, and the interactive-form go in the same slots as for byte-code functions. - the body of the function goes in the slot used for the bytecode string. - the lexical context goes in the slot used for the constants of bytecoded functions. The first point above means that `help-function-arglist`, `documentation`, and `interactive-form`s don't need to distinguish interpreted and bytecode functions any more. Main benefits of the change: - We can now reliably distinguish a list from a function value. - `cl-defmethod` can dispatch on `interactive-function` and `closure`. Dispatch on `function` also works now for interpreted functions but still won't work for functions represented as lists or as symbols, of course. - Function values are now self-evaluating. That was alrready the case when byte-compiled, but not when interpreted since (eval '(closure ...)) signals a void-function error. That also avoids false-positive warnings about "don't quote your lambdas" when doing things like `(mapcar ',func ...)`. * src/eval.c (Fmake_interpreted_closure): New function. (Ffunction): Use it and change calling convention of `Vinternal_make_interpreted_closure_function`. (FUNCTIONP, Fcommandp, eval_sub, funcall_general, funcall_lambda) (Ffunc_arity, lambda_arity): Simplify. (funcall_lambda): Adjust to new representation. (syms_of_eval): `defsubr` the new function. Remove definition of `Qclosure`. * lisp/emacs-lisp/cconv.el (cconv-make-interpreted-closure): Change calling convention and use `make-interpreted-closure`. * src/data.c (Fcl_type_of): Distinguish `byte-code-function`s from `interpreted-function`s. (Fclosurep, finterpreted_function_p): New functions. (Fbyte_code_function_p): Don't be confused by `interpreted-function`s. (Finteractive_form, Fcommand_modes): Simplify. (syms_of_data): Define new type symbols and `defsubr` the two new functions. * lisp/emacs-lisp/cl-print.el (cl-print-object) <interpreted-function>: New method. * lisp/emacs-lisp/oclosure.el (oclosure): Refine the parent to be `closure`. (oclosure--fix-type, oclosure-type): Simplify.

(byte-code-function): Add it as a parent. (interpreted-function): Adjust parent (the type itself was already added earlier by accident). * lisp/emacs-lisp/bytecomp.el (byte-compile--reify-function): Adjust to new representation. (byte-compile): Use `interpreted-function-p`. * lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand): Adjust to new representation. (side-effect-free-fns): Add `interpreted-function-p` and `closurep`. * src/profiler.c (trace_hash, ffunction_equal): Simplify. * lisp/profiler.el (profiler-function-equal): Simplify. * lisp/emacs-lisp/nadvice.el (advice--interactive-form-1): Use `interpreted-function-p`; adjust to new representation; and take advantage of the fact that function values are now self-evaluating. * lisp/emacs-lisp/lisp-mode.el (closure): Remove `lisp-indent-function` property. * lisp/emacs-lisp/disass.el (disassemble-internal): Adjust to new representation. * lisp/emacs-lisp/edebug.el (edebug--strip-instrumentation): Use `interpreted-function-p`. * lisp/emacs-lisp/comp-common.el (comp-known-type-specifiers): Add `closurep` and `interpreted-function-p`. * test/lisp/help-fns-tests.el (help-fns-test-lisp-defun): Adjust to more precise type info in `describe-function`. * test/lisp/erc/resources/erc-d/erc-d-tests.el (erc-d--render-entries): Use `interpreted-function-p`. * test/lisp/emacs-lisp/macroexp-resources/vk.el (vk-f4, vk-f5): Don't hardcode function values. * doc/lispref/functions.texi (Anonymous Functions): Don't suggest that function values are lists.

* (COMPILED): Rename to CLOSUREStefan Monnier2024-04-281-3/+3
| | | | | | | | | | | | | | | | | | In preparation for the use of `PVEC_COMPILED` objects for interpreted functions, rename them to use a more neutral name. * src/lisp.h (enum pvec_type): Rename `PVEC_COMPILED` to `PVEC_CLOSURE`.

(xcompiled): New obsolete alias. (xpr): Adjust accordingly. Also adjust to new PVEC_CLOSURE tag name.
* Share hash table test structsMattias Engdegård2024-01-131-1/+1
| | | | | | | | | | | | | | | | This saves several words in the hash table object at the cost of an indirection at runtime. This seems to be a gain in overall performance. FIXME: We cache hash test objects in a rather clumsy way. A better solution is sought. * src/lisp.h (struct Lisp_Hash_Table): Use a pointer to the test struct. All references adapted. * src/alloc.c (garbage_collect): * src/fns.c (struct hash_table_user_test, hash_table_user_tests) (mark_fns, get_hash_table_user_test): New state for caching test structs, and functions managing it.
* Remove rehash-threshold and rehash-size struct membersMattias Engdegård2024-01-131-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Represent hash table weakness as an enum internallyMattias Engdegård2024-01-131-1/+1
| | | | | | | | | | | | | | | | 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.
* Decouple profiler from Lisp hash table internalsMattias Engdegård2024-01-121-204/+283
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the table overflows and wh evict entries, keep track of those counts in a global counter so we can see the proportion of samples this represents. * src/profiler.c (struct profiler_log): Add `discarded` field. (evict_lower_half): Change arg to be `struct profiler_log`. Transfer counts to the new `discarded` field. (record_backtrace): Change arg to be `struct profiler_log`.

* Update copyright year to 2018Paul Eggert2018-01-011-1/+1

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-1/+1
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.
* Use float instead of Lisp_Object for rehash_sizePaul Eggert2017-02-211-3/+2
| | | | | | | | | | | | | | | | | | * src/alloc.c (purecopy_hash_table): * src/fns.c (maybe_resize_hash_table, Fmake_hash_table): (Fhash_table_rehash_size): * src/lisp.h (struct Lisp_Hash_Table.rehash_size): The rehash_size member of struct Lisp_Hash_Table is now a float, not a Lisp_Object. * src/alloc.c (purecopy_hash_table): Assign members in order. * src/fns.c (make_hash_table): Use EMACS_INT for size and float for rehash_size, instead of Lisp_Object for both. All callers changed. * src/lisp.h (DEFAULT_REHASH_SIZE): Now float, not double, and 1 smaller. * src/print.c (print_object): Simplify by calling Fhash_table_rehash_size and Fhash_table_rehash_threshold. Avoid unnecessary NILP.
* Use ptrdiff_t instead of Lisp_Object for collisionPaul Eggert2017-02-211-5/+5
| | | | | | | | | | | | | | | | | | | | | | * src/alloc.c (purecopy_hash_table): Assign, don’t purecopy. * src/fns.c (set_hash_next_slot, set_hash_index_slot): Hash index arg is now ptrdiff_t index (or -1 if empty), not Lisp_Object integer (or Qnil if empty). All callers changed. (larger_vecalloc): New static function. (larger_vector): Use it. (HASH_NEXT, HASH_INDEX): Move here from lisp.h. Return ptrdiff_t index (or -1) not Lisp_Object integer (or Qnil). All callers changed. * src/fns.c (make_hash_table, maybe_resize_hash_table, hash_lookup) (hash_put, hash_remove_from_table, hash_clear, sweep_weak_table): * src/profiler.c (evict_lower_half, record_backtrace): -1, not nil, is now the convention for end of collision list. * src/fns.c (maybe_resize_hash_table): Avoid double-initialization of the free list. Reallocate H->next last, in case other reallocations exhaust memory. * src/lisp.h (struct Lisp_Hash_Table): ‘next_free’ is now ptrdiff_t, not Lisp_Object. Adjust commentary for ‘next’ and ‘index’, which no longer contain nil. (HASH_NEXT, HASH_INDEX): Move to src/fns.c.
* Change type of `rehash_threshold' and `pure' fields in hash-tablesStefan Monnier2017-02-181-2/+2
| | | | | | | | | | | | * src/lisp.h (struct Lisp_Hash_Table): Change type of `rehash_threshold' and `pure' fields and move them after `count'. * src/fns.c (make_hash_table): Change type of `rehash_threshold' and `pure'. (Fmake_hash_table, Fhash_table_rehash_threshold): * src/category.c (hash_get_category_set): * src/xterm.c (syms_of_xterm): * src/profiler.c (make_log): * src/print.c (print_object): * src/alloc.c (purecopy_hash_table, purecopy): Adjust accordingly.
* Fix hash tables not being purified correctly.Vibhav Pant2017-01-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | * src/alloc.c (purecopy_hash_table) New function, makes a copy of the given hash table in pure storage. Add new struct `pinned_object' and `pinned_objects' linked list for pinning objects. (Fpurecopy) Allow purifying hash tables (purecopy) Pin hash tables that are either weak or not declared with `:purecopy t`, use purecopy_hash_table otherwise. (marked_pinned_objects) New function, marks all objects in pinned_objects. (garbage_collect_1) Use it. Mark all pinned objects before sweeping. * src/lisp.h Add new field `pure' to struct `Lisp_Hash_Table'. * src/fns.c: Add `purecopy' parameter to hash tables. (Fmake_hash_table): Check for a `:purecopy PURECOPY' argument, pass it to make_hash_table. (make_hash_table): Add `pure' parameter, set h->pure to it. (Fclrhash, Fremhash, Fputhash): Enforce that the table is impure with CHECK_IMPURE. * src/lread.c: (read1) Parse for `purecopy' parameter while reading hash tables. * src/print.c: (print_object) add the `purecopy' parameter while printing hash tables. * src/category.c, src/emacs-module.c, src/image.c, src/profiler.c, src/xterm.c: Use new (make_hash_table).
