* Correctly cache images when frames vary in their font metricsPo Lu2024-06-201-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/alloc.c (mark_frame): Mark this frame's image cache, if it exist.

This excludes only those symbols which are interned and referenced only once during Emacs's initialization, the timing of whose interning is inconsequential, and symbols in w32.c, which would need to be transferred to a new syms_of_w32 function that I cannot test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/cus-edit.el (Custom-mode): Enable text conversion, now that fields are correctly treated. * src/alloc.c (mark_frame): Mark f->conversion.field. * src/androidterm.c (android_update_selection): Adjust conversion region and selection position by the field start and end. * src/editfns.c (find_field): Export function. * src/frame.c (make_frame): Clear f->conversion.field. * src/frame.h (struct text_conversion_state) <field>: New field. * src/lisp.h (find_fields, reset_frame_conversion): Export functions. * src/minibuf.c (Fread_from_minibuffer): Reset frame conversion if Voverriding_text_conversion_style is set. * src/textconv.c (textconv_query): Narrow to field.

| | | | | | | | | | | | | | | | | | 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`. (enum Lisp_Compiled): Use `CLOSURE_` prefix i.s.o `COMPILED_`. Also use `CODE` rather than `BYTECODE`. (CLOSUREP): Rename from `COMPILEDP`.

* Revert "Replace XSETSYMBOL with make_lisp_symbol"Mattias Engdegård2024-03-041-4/+8
| | | | | | | | This reverts commit de6b1e1efb1a36c69e7a6e09297e1de5b1477121. While it did simplify code, there aren't much in the way of technical benefits the change at this time, and there were protest against the unwarranted style change.
* Replace XSETSYMBOL with make_lisp_symbolMattias Engdegård2024-02-241-8/+4
| | | | | * src/lisp.h (XSETSYMBOL): Remove. All callers changed to use make_lisp_symbol.
* Add a proper type for obarraysMattias Engdegård2024-02-231-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new opaque type replaces the previous use of vectors for obarrays. `obarray-make` now returns objects of this type. Functions that take obarrays continue to accept vectors for compatibility, now just using their first slot to store an actual obarray object. obarray-size and obarray-default-size now obsolete. * lisp/obarray.el (obarray-default-size, obarray-size): Declare obsolete. (obarray-make, obarrayp, obarray-clear): Remove from here. * src/fns.c (reduce_emacs_uint_to_hash_hash): Remove from here. * src/lisp.h (struct Lisp_Obarray, OBARRAYP, XOBARRAY, CHECK_OBARRAY) (make_lisp_obarray, obarray_size, check_obarray) (obarray_iter_t, make_obarray_iter, obarray_iter_at_end) (obarray_iter_step, obarray_iter_symbol, DOOBARRAY, knuth_hash): New.

(obarray_index, allocate_obarray, make_obarray, grow_obarray) (obarray_default_bits, Fobarray_make, Fobarrayp, Fobarray_clear): New. * etc/emacs_lldb.py (Lisp_Object): * lisp/emacs-lisp/cl-macs.el (`(,type . ,pred)): * lisp/emacs-lisp/cl-preloaded.el (cl--typeof-types): * lisp/emacs-lisp/comp-common.el (comp-known-type-specifiers): * lisp/emacs-lisp/comp.el (comp-known-predicates): * src/alloc.c (cleanup_vector, process_mark_stack): * src/data.c (Ftype_of, syms_of_data): * src/minibuf.c (Ftry_completion, Fall_completions, Ftest_completion): * src/pdumper.c (dump_obarray_buckets, dump_obarray, dump_vectorlike): * src/print.c (print_vectorlike_unreadable): * test/lisp/abbrev-tests.el (abbrev-make-abbrev-table-test): * test/lisp/obarray-tests.el (obarrayp-test) (obarrayp-unchecked-content-test, obarray-make-default-test) (obarray-make-with-size-test): Adapt to new type.
* Replace XSET_HASH_TABLE with make_lisp_hash_tableMattias Engdegård2024-02-191-2/+1
| | | | | * src/lisp.h (XSET_HASH_TABLE): Remove, replace with... (make_lisp_hash_table): ...this. All callers adapted.
* Change hash range reduction from remainder to multiplicationMattias Engdegård2024-02-061-3/+4
| | | | | | | | | | | | | | | | This makes both lookups and rehashing cheaper. The index vector size is now always a power of 2. The first table size is reduced to 6 (from 8), because index vectors would become excessively big otherwise. * src/lisp.h (struct Lisp_Hash_Table): Replace index_size with index_bits. All references adapted. (hash_table_index_size): New accessor; use it where applicable. * src/fns.c (hash_index_size): Replace with... (compute_hash_index_bits): ...this new function, returning the log2 of the index size. All callers adapted. (hash_index_index): Knuth multiplicative hashing instead of remainder. (maybe_resize_hash_table): Reduce first table size from 8 to 6.
* Prefer C23 ckd_* to Gnulib *_WRAPV and *_OK macrosPaul Eggert2024-01-281-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | * src/alloc.c (android_make_lisp_symbol) [HAVE_ANDROID && !__clang__]: * src/android.c (android_blit_copy, android_blit_xor) (android_get_image): * src/androidmenu.c (android_menu_show): * src/androidselect.c (Fandroid_get_clipboard_data) (android_notifications_notify_1): * src/androidterm.c (android_decode_utf16) (android_text_to_string): * src/haiku_select.cc (be_display_notification): * src/sfnt.c (sfnt_read_cmap_format_8, sfnt_read_cmap_format_12) (sfnt_read_cmap_format_14, sfnt_read_cmap_table_1) (sfnt_expand_compound_glyph_context, sfnt_poly_edges_exact) (sfnt_read_meta_table, sfnt_read_ttc_header) (sfnt_read_cvt_table, sfnt_read_fpgm_table) (sfnt_read_prep_table, sfnt_make_interpreter) (sfnt_interpret_simple_glyph, sfnt_interpret_compound_glyph_2) (sfnt_interpret_compound_glyph, sfnt_read_default_uvs_table) (sfnt_read_nondefault_uvs_table, sfnt_create_uvs_context) (sfnt_read_fvar_table, sfnt_read_gvar_table) (sfnt_read_avar_table, sfnt_read_cvar_table): * src/sfntfont-android.c (GET_SCANLINE_BUFFER): * src/textconv.c (really_commit_text, really_set_composing_text) (really_replace_text, get_surrounding_text): Prefer C2x stdckdint.h macros to intprops.h macros.
* Rename TAG_PTR to TAG_PTR_INITIALLYPaul Eggert2024-01-281-1/+1
| | | | | | | | * src/lisp.h (TAG_PTR_INITIALLY): Rename from TAG_PTR, since calls can be used only as initializers, and the convention elsewhere in lisp.c is to give these macros names ending in ‘_INITIALLY’. This should help avoid confusion such as we recently experienced in make_lisp_symbol_internal. All uses changed.
* (struct composition): Remove dependency on hash-table internalsStefan Monnier2024-01-241-0/+2
| | | | | | | | | | | | | | | | | | | | | `struct composition` kept an index into the internal `key_and_value` array of hash tables, which only worked because of details of how hash-tables are handled. Replace it with a reference to the key stored at that location in the hash-table, which saves us an indirection while at it. * src/composite.h (struct composition): Replace `hash_index` with the actual `key`. (COMPOSITION_KEY): Simplify accordingly. (mark_composite): Declare. * src/composite.c (get_composition_id): Adjust accordingly. (mark_composite): New function. * src/charset.c (mark_charset): Uncomment. * src/lisp.h (mark_charset): Declare. * src/alloc.c (garbage_collect): Call `mark_charset` and `mark_composite`. * src/pdumper.c (hash_table_contents): Remove invalid comment, since compositions aren't dumped.
* Change HASH_UNUSED_ENTRY_KEY from Qunbound to NULL floatMattias Engdegård2024-01-211-8/+16
| | | | | | | | | | | | | This removes hacks from code that had to be careful not to use Qunbound as a hash table key, at the cost of a minor hack in the GC marker. * src/lisp.h (INVALID_LISP_VALUE, HASH_UNUSED_ENTRY_KEY): Define as a null-pointer float. * src/alloc.c (process_mark_stack): Add hack to ignore that value. * src/pdumper.c (dump_object_needs_dumping_p) (pdumper_init_symbol_unbound, pdumper_load): * src/print.c (PRINT_CIRCLE_CANDIDATE_P): Remove hacks for Qunbound.
* Be more systematic about parens in C source codePaul Eggert2024-01-201-25/+25
| | | | | | | | | Be more systematic about putting space before paren in calls, and in avoiding unnecessary parentheses in macros. This was partly inspired by my wading through gcc -E output while debugging something else, and seeing too many parens. This patch does not change the generated .o files on my platform.
* Share hash table test structsMattias Engdegård2024-01-131-7/+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.
* Use non-Lisp allocation for internal hash-table vectorsMattias Engdegård2024-01-131-11/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using xmalloc for allocating these arrays is much cheaper than using Lisp vectors since they are no longer marked or swept by the GC, and deallocated much sooner. This makes GC faster and less frequent, and improves temporal locality. Zero-sized tables use NULL for their (0-length) vectors except the index vector which has size 1 and uses a shared constant static vector since it cannot be modified anyway. This makes creation and destruction of zero-sized hash tables very fast; they consume no memory outside the base object. * src/lisp.h (struct Lisp_Hash_Table): Retype the index, next, hash and key_and_value vectors from Lisp_Object to appropriately typed arrays (although hash values are still stored as Lisp fixnums). Add explicit table_size and index_size members. All users updated. * src/alloc.c (gcstat): Add total_hash_table_bytes. (hash_table_allocated_bytes): New. (cleanup_vector): Free hash table vectors when sweeping the object. (hash_table_alloc_bytes, hash_table_free_bytes): New. (sweep_vectors): Update gcstat.total_hash_table_bytes. (total_bytes_of_live_objects): Use it. (purecopy_hash_table): Adapt allocation of hash table vectors. (process_mark_stack): No more Lisp slots in the struct to trace. * src/fns.c (empty_hash_index_vector): New. (allocate_hash_table): Allocate without automatically GCed slots. (alloc_larger_vector): Remove. (make_hash_table, copy_hash_table, maybe_resize_hash_table): Adapt vector allocation and initialisation. * src/pdumper.c (hash_table_freeze, hash_table_thaw, dump_hash_table) (dump_hash_table_contents): Adapt dumping and loading to field changes.
* Allow zero hash table sizeMattias Engdegård2024-01-131-1/+2
| | | | | | | | | | | This avoids any extra allocation for such vectors, including empty tables read by the Lisp reader, and provides extra safety essentially for free. * src/fns.c (make_hash_table): Allow tables to be 0-sized. The index will always have at least one entry, to avoid extra look-up costs. * src/alloc.c (process_mark_stack): Don't mark pure objects, because empty vectors are pure.
* Represent hash table weakness as an enum internallyMattias Engdegård2024-01-131-3/+3
| | | | | | | | | | | | | | | | 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.
* ; * src/alloc.c (purecopy_hash_table): SimplifyMattias Engdegård2024-01-121-15/+5
| | | | | Copy the entire struct, then take care of fields needing special treatment.
* Decouple profiler from Lisp hash table internalsMattias Engdegård2024-01-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Delete obsolete GC debugging codeStefan Kangas2024-01-031-102/+0
| | | | | | | | | | | | | | | | | | | | This code was introduced in 2014 to catch a GC bug that, according to Paul Eggert in 2019, "seems to have been fixed" (see 2b552f34892 2019-08-21 "Don’t debug fset by default"). It has been marked obsolete since that time, and no one has mentioned it on our mailing lists since. Let's just get rid of it. * src/alloc.c (SUSPICIOUS_OBJECT_CHECKING) [ENABLE_CHECKING]: Don't define. (suspicious_free_record, suspicious_objects, suspicious_object_index) (suspicious_free_history, suspicious_free_history_index) (note_suspicious_free) [SUSPICIOUS_OBJECT_CHECKING]: Delete.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally discovered by Tyler Dodge in his article "Significant Garbage Collection Improvement For Emacs". While testing this change on Archlinux system with Intel i5-7200U CPU, average time of garbage collection gets reduced by ≈25%. Other users report improvements up to 50%. While monitoring PSS of emacs with and without customizations loaded before and after the patch, no statistically significant differences were discovered. So overall, this change is a win. * src/alloc.c (BLOCK_ALIGN): increase from 1024 to 32768.
