* Don't build print-number-table unless it will be usedGemini Lasswell2019-09-131-53/+39
| | | | | | | | | | | | | | | | | | There are only a few users of print-number-table, and none of them use it when print-circle is nil. A couple of them used to. print_object was changed in 2012-04-20 "* src/print.c (print_preprocess): Only check print_depth if print-circle is nil". byte-compile-output-docform which uses print-number-table binds print-circle to t before printing unless byte-compile-disable-print-circle is set, but that variable has been marked obsolete since 24.1. * src/print.c (print_preprocess): Assert Vprint_circle is non-nil. Remove code handling the case when Vprint_circle is nil. (print, Fprint_preprocess): Don't call print_preprocess unless Vprint_circle is non-nil. (print_object): Remove comment referencing removed code in print_preprocess.
* Fix unnecessary hash table creation in cl-prin1 (bug#36566)Gemini Lasswell2019-09-131-2/+6
| | | | | | | | | | | | cl-prin1 prints all its punctuation by passing strings to prin1. When print-circle was set, print_preprocess was creating a new hash table for each string, causing excessive garbage collection when printing large Lisp objects with cl-prin1. * src/print.c (print_number_index): Fix typo in comment above. (PRINT_CIRCLE_CANDIDATE_P): Don't create print_number_table for top-level strings with no properties, except when print_continuous_numbering is on.
* Adjust remaining uses of `NILP (HASH_HASH)`.Stefan Monnier2019-07-261-10/+16
| | | | | | | | * src/json.c (lisp_to_json_toplevel_1): * src/pdumper.c (dump_hash_table_stable_p, hash_table_contents): * src/print.c (print, print_vectorlike): * src/minibuf.c (Ftry_completion, Fall_completions, Ftest_completion): Use `EQ (HASH_KEY, Qunbound)` instead of `NILP (HASH_HASH)`.
* Rename ‘pure’ to ‘purecopy’Paul Eggert2019-07-201-2/+2
| | | | | | * 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.
* Use fewer locks when accessing stdioPaul Eggert2019-07-081-6/+6

* Remove printmax_t etc.Paul Eggert2019-07-071-11/+11
| | | | | | | | | | | | printmax_t etc. were needed only for platforms that lacked support for printing intmax_t. These platforms are now so obsolete that they are no longer practical porting targets. * src/image.c (gs_load): Fix unlikely buffer overrun discovered while making these changes. It was introduced in 2011-07-17T00:34:43!eggert@cs.ucla.edu. * src/lisp.h (printmax_t, uprintmax_t, pMd, pMu, pMx): Remove. All uses replaced by their standard counterparts intmax_t, uintmax_t, PRIdMAX, PRIuMAX, PRIxMAX.
* Use simpler way to print function pointersPaul Eggert2019-05-051-21/+26
| | | | | | | | | | | | | The module code can’t possibly work on weird platforms where function pointers are wider than data pointers, so there’s no need to bother with the stackoverflow-like approach that is intended only for portability to such platforms. Besides, the stackoverflow-like approach does not work well on weird platforms where CHAR_BIT is not a multiple of 4. * src/lisp.h (pMx): New macro. * src/print.c (data_from_funcptr) [HAVE_MODULES]: New function. (print_vectorlike) [HAVE_MODULES]: Use it. (print_object): Make sure buf is big enough for this.
* Avoid compiler warning in print.cEli Zaretskii2019-05-051-1/+1
| | | | | | * src/print.c (print_vectorlike): Don't use %hh, as that is not portable enough; we don't yet assume a C99-compliant library.
* Avoid undefined behavior when printing function pointers.Philipp Stephani2019-05-041-11/+18
| | | | | | * src/print.c (print_vectorlike): Don’t pass a function pointer to ‘snprintf’, as that is undefined behavior. Instead, print the individual bytes making up the function pointer.
* Port to Oracle Developer Studio 12.6Paul Eggert2019-04-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This compiler is a bit pickier about checking conformance to the C standard, ranging from syntax trivia (no extra ";" at the top level) to portability trivia (warnings re conversion between function and data pointers) to more-important stuff like lack of support for some __attribute__ usages. * src/dynlib.c (dynlib_addr): First argument is a function pointer, not a data pointer. All callers changed. * src/emacs-module.c (module_function_address): Return module_funcptr, not void *. All uses changed. * src/lisp.h (module_funcptr) [HAVE_MODULES]: New type. * src/lread.c (union ieee754_double): Don’t assume the usual semantics for converting signed to unsigned int when initializing a bitfield, as the Oracle compiler complains and the C standard is unclear. * src/pdumper.c (ALLOW_IMPLICIT_CONVERSION): Make it clearer that -Wsign-conversion is disabled everywhere in this file. (dump_trace, dump_tailq_prepend, dump_tailq_append): Don’t assume __attribute__. (dump_object_self_representing_p): Don’t disable conversion warnings; it’s not needed here. (DEFINE_FROMLISP_FUNC): Avoid possible signal in integer conversion from unsigned to signed. (DEFINE_FROMLISP_FUNC, finish_dump_pvec): Avoid warning about unreachable statements on platforms not supporting the __attribute__. (intmax_t_from_lisp, intmax_t_to_lisp, dump_off_from_lisp) (dump_off_to_lisp, dump_emacs_reloc_immediate_lv) (dump_emacs_reloc_immediate_ptrdiff_t) (dump_emacs_reloc_immediate_intmax_t) (dump_emacs_reloc_immediate_int, dump_emacs_reloc_immediate_bool): Omit stray semicolon that violates C standard. (dump_metadata_for_pdumper): Add cast to pacify compiler complaining about conversion from function pointer to data pointer. (Fdump_emacs_portable): Do not use CALLN to call a function with zero arguments, as C99 prohibits empty initializers. * src/xdisp.c (syms_of_xdisp): Do not nest calls to pure_list, to work around a bug in Oracle Developer Studio 12.6.
* Move definition of Lisp_Module_Function to emacs-module.c.Philipp Stephani2019-04-241-2/+2
| | | | | | | | | | | | | * src/lisp.h: Remove include of emacs-module.h. Remove definition of Lisp_Module_Function structure. * src/emacs-module.c (module_function_documentation) (module_function_address): New accessor functions for module function fields. (emacs_subr, struct Lisp_Module_Function): Move from lisp.h. * src/print.c (print_vectorlike): * src/doc.c (Fdocumentation): Use the new accessor functions.
* Remove some #ifdefs for user pointers.Philipp Stephani2019-04-191-2/+0
| | | | | | | | | | | | | | | | | Even if Emacs is compiled without module support, we don't have to comment out every bit of user pointer support. Defining the basic structures and functions and detecting user pointers in switch statements is harmless, and we're already doing the same for module functions. Removing these #ifdefs makes the code a bit easier to read. * src/lisp.h (PVEC_USER_PTR, struct Lisp_User_Ptr, USER_PTRP) (XUSER_PTR): Define unconditionally. * src/data.c (Ftype_of): * src/alloc.c (cleanup_vector): * src/print.c (print_vectorlike): * src/pdumper.c (dump_vectorlike): Remove #ifdef for user pointers.

* | Fix mishandling of symbols that look like numbersPaul Eggert2018-10-101-34/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/bignum.c (make_neg_biguint): New function. * src/lread.c (read1): Do not mishandle an unquoted symbol with name equal to something like "1\0x", i.e., a string of numeric form followed by a NUL byte. Formerly these symbols were misread as numbers. (string_to_number): Change last argument from an integer flag to a pointer to the length. This lets the caller figure out how much of the prefix was used. All callers changed. Add a fast path if the integer (sans sign) fits in uintmax_t. Update comments and simplify now that bignums are present. * src/print.c (print_object): Fix quoting of symbols that look like numbers, by relying on string_to_number for the tricky cases rather than trying to redo its logic, incorrectly. For example, (read (prin1-to-string '\1e+NaN)) formerly returned "1e+NaN", which was wrong: a backslash is needed in the output to prevent it from being read as a NaN. Escape NO_BREAK_SPACE too, since lread.c treats it like SPACE. * test/src/print-tests.el (print-read-roundtrip): Add tests illustrating the abovementioned bugs.
* | Several fixes for formatting bignumsPaul Eggert2018-08-311-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/bignum.c: Include stdlib.h, for abs. (bignum_bufsize, bignum_to_c_string): New functions. * src/bignum.c (bignum_to_string): * src/print.c (print_vectorlike): Use them. * src/editfns.c (styled_format): Instead of having a separate buffer for sprintf (which does not work for bignums), just append to the main buffer. When formatting bignums, add support for the standard integer flags -, #, 0, + and space. Fix some comments. Capitalize properly when formatting bignums with %X. Use functions like c_isdigit rather than reinventing the wheel. Simplify computation of excess precision. * src/print.c: Do not include bignum.h; no longer needed. (print_vectorlike): Avoid recalculating string length. * test/src/editfns-tests.el (format-bignum): Test some of the above fixes.
* | Modularize bignums betterPaul Eggert2018-08-271-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/bignum.c, src/bignum.h: New files. Only modules that need to know how bignums are implemented should include bignum.h. Currently these are alloc.c, bignum.c (of course), data.c, emacs.c, emacs-module.c, floatfns.c, fns.c, print.c. * src/Makefile.in (base_obj): Add bignum.o. * src/alloc.c (make_bignum_str): Move to bignum.c. (make_number): Remove; replaced by bignum.c’s make_integer. All callers changed. * src/conf_post.h (ARG_NONNULL): New macro. * src/json.c (json_to_lisp): Use it. * src/data.c (Fnatnump): Move NATNUMP’s implementation here from lisp.h. * src/data.c (Fnumber_to_string): * src/editfns.c (styled_format): Move conversion of string to bignum to bignum_to_string, and call it here. * src/emacs-module.c (module_make_integer): * src/floatfns.c (Fabs): Simplify by using make_int. * src/emacs.c: Include bignum.h, to expand its inline fns. * src/floatfns.c (Ffloat): Simplify by using XFLOATINT. (rounding_driver): Simplify by using double_to_bignum. (rounddiv_q): Clarify use of temporaries. * src/lisp.h: Move decls that need to know bignum internals to bignum.h. Do not include gmp.h or mini-gmp.h; that is now bignum.h’s job. (GMP_NUM_BITS, struct Lisp_Bignum, XBIGNUM, mpz_set_intmax): Move to bignum.h. (make_int): New function. (NATNUMP): Remove; all callers changed to use Fnatnump. (XFLOATINT): If arg is a bignum, use bignum_to_double, so that bignum internals are not exposed here. * src/print.c (print_vectorlike): Use SAFE_ALLOCA to avoid the need for a record_unwind_protect_ptr.
* | Turn misc objects into pseudovectorsPaul Eggert2018-08-111-91/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eliminate the category of miscellaneous objects, and turn all such objects into pseudovectors. The immediate motivation for this change is to free up an enum Lisp_Type tag value, a scarce resource that can be better used elsewhere. However, this change is worthwhile in its own right, as it improves performance slightly on my platform, 0.3% faster for 'make compile-always' on Fedora 28, and it simplifies the garbage collector and interpreter (Bug#32405). * doc/lispref/internals.texi (Garbage Collection): * etc/NEWS: Document change to garbage-collect return value. * src/alloc.c (total_markers, total_free_markers): (union aligned_Lisp_Misc, MARKER_BLOCK_SIZE) (struct marker_block, marker_block, marker_block_index) (misc_free_list, allocate_misc, live_misc_holding) (live_misc_p, sweep_misc): * src/lisp.h (lisp_h_MARKERP, lisp_h_MISCP, MARKERP, MISCP) (Lisp_Misc, enum Lisp_Misc_Type, Lisp_Misc_Free) (Lisp_Misc_Marker, Lisp_Misc_Overlay, Lisp_Misc_Finalizer) (Lisp_Misc_Ptr, Lisp_Misc_User_Ptr, Lisp_Misc_Limit) (Lisp_Misc_Bignum) (XSETMISC, struct Lisp_Misc_Any, XMISCANY, XMISCTYPE) (struct Lisp_Free, union Lisp_Misc, XMISC): Remove. All uses removed. (cleanup_vector): Clean up objects that were formerly misc and are now pseudovectors. (make_misc_ptr, build_overlay, Fmake_marker, build_marker) (make_bignum_str, make_number, make_pure_bignum) (make_user_ptr, Fmake_finalizer): Build as pseudovectors, not as misc objects. (mark_finalizer_list, queue_doomed_finalizers) (compact_undo_list, mark_overlay, mark_object) (unchain_dead_markers): Mark as vector-like objects, not as misc objects. (mark_maybe_object, mark_maybe_pointer, valid_lisp_object_p) (total_bytes_of_live_objects, survives_gc_p): * src/fns.c (sxhash): No need to worry about misc objects. (garbage_collect_1): Do not generate a 'misc' component. (syms_of_alloc): No need for 'misc' symbol. * src/buffer.c (overlays_at, overlays_in, overlay_touches_p) (overlay_strings, recenter_overlay_lists) (fix_start_end_in_overlays, fix_overlays_before) (Foverlay_lists, report_overlay_modification) (evaporate_overlays): * src/editfns.c (overlays_around): * src/data.c (Ftype_of): * src/fns.c (internal_equal): * src/lisp.h (mint_ptrp, xmint_pointer, FINALIZERP) (XFINALIZER, MARKERP, XMARKER, OVERLAYP, XOVERLAY, USER_PTRP) (XUSER_PTR, BIGNUMP, XBIGNUM): * src/print.c (print_vectorlike, print_object): * src/undo.c (record_marker_adjustments): * src/xdisp.c (load_overlay_strings): Formerly misc objects are now pseudovectors. * src/lisp.h (PVEC_MARKER, PVEC_OVERLAY, PVEC_FINALIZER) (PVEC_BIGNUM, PVEC_MISC_PTR, PVEC_USER_PTR): New constants, replacing their misc versions. All uses changed. (struct Lisp_Marker, struct Lisp_Overlay, struct Lisp_Misc_Ptr) (struct Lisp_Bignum, struct Lisp_User_Ptr, struct Lisp_Finalizer): Make usable as a pseudovector by using a pseudovector header, replacing any DIY components, and putting Lisp_Object members first. All uses changed.

* 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.
* Improve stack-overflow heuristic on GNU/LinuxPaul Eggert2017-07-141-1/+1

* Fix core dump in substitute-object-in-subtreePaul Eggert2017-07-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this fix, (substitute-object-in-subtree #0=(#0# 'a) 'a) would dump core, since the C code would recurse indefinitely through the infinite structure. This patch adds an argument to the function, and renames it to lread--substitute-object-in-subtree as the function is not general-purpose and should not be relied on by outside code. See Bug#23660. * src/intervals.c (traverse_intervals_noorder): ARG is now void *, not Lisp_Object, so that callers need not cons unnecessarily. All callers changed. Also, remove related #if-0 code that was “temporary” in the early 1990s and has not been compilable for some time. * src/lread.c (struct subst): New type, for substitution closure data. (seen_list): Remove this static var, as this info is now part of struct subst. All uses removed. (Flread__substitute_object_in_subtree): Rename from Fsubstitute_object_in_subtree, and give it a 3rd arg so that it doesn’t dump core when called from the top level with an already-cyclic structure. All callers changed. (SUBSTITUTE): Remove. All callers expanded and then simplified. (substitute_object_recurse): Take a single argument SUBST rather than a pair OBJECT and PLACEHOLDER, so that its address can be passed around as part of a closure; this avoids the need for an AUTO_CONS call. All callers changed. If the COMPLETED component is t, treat every subobject as potentially circular. (substitute_in_interval): Take a struct subst * rather than a Lisp_Object, for the closure data. All callers changed. * test/src/lread-tests.el (lread-lread--substitute-object-in-subtree): New test, to check that the core dump does not reoccur.
* Escape control characters in backtraces (Bug#6991)Noam Postavsky2017-06-291-12/+33
| | | | | | | | | | * src/print.c (syms_of_print): Add new variable, print-escape-control-characters. (print_object): Print control characters with octal escape codes when print-escape-control-characters is true. * lisp/subr.el (backtrace): * lisp/emacs-lisp/debug.el (debugger-setup-buffer): Bind `print-escape-control-characters' to t.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This can improve performance significantly on stdio-bottlenecked code. E.g., make-docfile is 3x faster on my Fedora 25 x86-64 desktop. * admin/merge-gnulib (GNULIB_MODULES): Add unlocked-io. * lib-src/ebrowse.c, lib-src/emacsclient.c, lib-src/etags.c: * lib-src/hexl.c, lib-src/make-docfile.c, lib-src/movemail.c: * lib-src/profile.c, lib-src/update-game-score.c: Include unlocked-io.h instead of stdio.h, since these programs are single-threaded. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/unlocked-io.h, m4/unlocked-io.m4: New files, copied from Gnulib. * src/charset.c, src/cm.c, src/emacs.c, src/image.c, src/keyboard.c: * src/lread.c, src/term.c: Include sysstdio.h, possibly instead of stdio.h, to define the unlocked functions if the system does not provide them. * src/charset.c, src/lread.c (getc_unlocked): Remove, since sysstdio.h now defines it if needed. * src/cm.c (cmputc, cmcheckmagic): * src/dispnew.c (update_frame, update_frame_with_menu) (update_frame_1, Fsend_string_to_terminal, Fding, bitch_at_user): * src/emacs.c (main, Fdump_emacs): * src/fileio.c (Fdo_auto_save, Fset_binary_mode): * src/image.c (slurp_file, png_read_from_file, png_load_body) (our_stdio_fill_input_buffer): * src/keyboard.c (record_char, kbd_buffer_get_event, handle_interrupt): * src/lread.c (readbyte_from_file): * src/minibuf.c (read_minibuf_noninteractive): * src/print.c (printchar_to_stream, strout) (Fredirect_debugging_output): * src/sysdep.c (reset_sys_modes, procfs_ttyname) (procfs_get_total_memory): * src/term.c (tty_ring_bell, tty_send_additional_strings) (tty_set_terminal_modes, tty_reset_terminal_modes) (tty_update_end, tty_clear_end_of_line, tty_write_glyphs) (tty_write_glyphs_with_face, tty_insert_glyphs) (tty_menu_activate): * src/xfaces.c (Fx_load_color_file): Use unlocked stdio when it should be safe. * src/sysstdio.h (clearerr_unlocked, feof_unlocked, ferror_unlocked) (fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked) (fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked) (putc_unlocked, putchar_unloced): Provide substitutes if not declared.

| | | | | | | | | | | | | | | | | | Fix a FIXME in emacs-module.c. Put the printing into print.c, like other types. * src/print.c (print_vectorlike): Add code to print module functions. * src/emacs-module.c (funcall_module): Stop calling 'module_format_fun_env'. Now that module functions are first-class objects, they can be added to signal data directly. (module_handle_signal): Remove now-unused function 'module_format_fun_env'. * test/src/emacs-module-tests.el (mod-test-sum-test): Adapt unit test. * src/eval.c (funcall_lambda): Adapt call to changed signature of 'funcall_module'.
* Pacify --enable-gcc-warnings without modulesPaul Eggert2017-05-211-384/+367
| | | | | | | | | * src/print.c (print_vectorlike): New function, taken from part of print_object. This one is indented properly, and pacifies --enable-gcc-warnings by using a default case instead of listing all the enum values, sometimes incompletely. (print_object): Use it.
* Reimplement module functionsPhilipp Stephani2017-05-201-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of a lambda, create a new type containing all data required to call the function, and support it in the evaluator. Because this type now also needs to store the function documentation, it is too big for Lisp_Misc; use a pseudovector instead. That also has the nice benefit that we don't have to add special support to the garbage collector. Since the new type is user-visible, give it a predicate. Now we can easily support 'help-function-args' and 'func-arity'; add unit tests for these. * src/lisp.h (allocate_module_function, MODULE_FUNCTIONP) (XMODULE_FUNCTION): New pseudovector type 'module function'. * src/eval.c (FUNCTIONP): Also treat module functions as functions. (funcall_lambda, Ffuncall, eval_sub): Add support for calling module functions. (Ffunc_arity): Add support for detecting the arity of module functions. * src/emacs-module.c (module_make_function): Adapt to new structure. Return module function object directly instead of wrapping it in a lambda; remove FIXME. (funcall_module): New function to call module functions. Replaces `internal--module-call' and is called directly from eval.c. (syms_of_module): Remove internal helper function, which is no longer needed. (module_function_arity): New helper function. * src/data.c (Ftype_of): Adapt to new implementation. (Fmodule_function_p, syms_of_data): New user-visible function. Now that module functions are first-class objects, they deserve a predicate. Define it even if not compiled with --enable-modules so that Lisp code doesn't have to check for the function's existence. * src/doc.c (Fdocumentation): Support module functions. * src/print.c (print_object): Adapt to new implementation. * src/alloc.c (mark_object): Specialized garbage collector support is no longer needed. * lisp/help.el (help-function-arglist): Support module functions. While there, simplify the arity calculation by using `func-arity', which does the right thing for all kinds of functions. * test/data/emacs-module/mod-test.c: Amend docstring so we can test the argument list. * test/src/emacs-module-tests.el (mod-test-sum-docstring): Adapt to new docstring. (mod-test-non-local-exit-signal-test): Because `internal--module-call' is gone, the backtrace has changed and no longer leaks the implementation. (module--func-arity): New test for `func-arity'. (module--help-function-arglist): New test for `help-function-arglist'.
* Introduce new misc type for module functionPhilipp Stephani2017-05-061-0/+5
