* | Fix bug with face-id after restoring from pdumpEli Zaretskii2019-01-281-0/+5
| | | | | | | | | | | | | | | | | | | | * src/xfaces.c (init_xfaces): New function. * src/emacs.c (main) [HAVE_PDUMPER]: If dumped with pdumper, call init_xfaces. (Bug#34226) * src/lisp.h (init_xfaces) [HAVE_PDUMPER]: Add prototype. * test/lisp/faces-tests.el (faces--test-face-id): New test for bug#34226.
* | Improve pdump load diagnosticsEli Zaretskii2019-01-271-4/+6
| | | | | | | | | | * src/emacs.c (load_pdump): Improve diagnostics when pdump file fails to load correctly.

* | Improve pdump file search and 'pdumper-stats'Eli Zaretskii2019-01-261-7/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/pdumper.c (pdumper_record_wd): New function. (pdumper_load): Use xstrdup instead of strdup, as on MS-Windows the latter uses the wrong heap. Don't free a NULL pointer. * src/emacs.c (load_pdump): Support the use case where the Emacs binary was renamed: look in exec-directory for the pdump file whose base name is derived from the Emacs binary, in addition to just emacs.pdmp. (main): Call pdumper_record_wd to prepend CWD to the pdump file name. * src/fileio.c (file_name_absolute_p): Now extern. * src/lisp.h (file_name_absolute_p): Add prototype. * src/pdumper.h (pdumper_record_wd): Add prototype. * doc/emacs/cmdargs.texi (Initial Options): Update the documentation of where Emacs looks for the dump file.

* | Clean up memory allocation and unexec support on MS-WindowsEli Zaretskii2019-01-181-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/w32heap.c (report_temacs_memory_usage): Condition on !CANNOT_DUMP, in addition to ENABLE_CHECKING. (init_heap): Accept an argument, which tells us what heap allocation method to use. (DUMPED_HEAP_SIZE) [CANNOT_DUMP]: Define to a small value, as we don't use dumped_data[] in this case. * src/w32heap.h (init_heap): Adjust prototype. <using_dynamic_heap>: Remove declaration. * src/emacs.c (main) [WINDOWSNT]: Determine heap allocation method based on whether we are in temacs and whether unexec will be used to dump Emacs. Pass the heap allocation method to init_heap, which is now called after parsing the --temacs=METHOD option. * src/unexw32.c (unexec): Don't fiddle with using_dynamic_heap. <using_dynamic_heap>: Remove definition. * src/w32proc.c (malloc_before_init, realloc_before_init) (free_before_init): New functions, to catch memory allocation before heap allocation method is set up.
* | Avoid compilation warnings in MS-Windows buildAndy Moreton2019-01-161-1/+1
| | | | | | | | | | | | * src/pdumper.c (dump_cold_bignum): * src/emacs.c(load_pdump) [WINDOWSNT]: Avoid compiler warnings due to 64-bit vs 32-bit data type mismatches.
* | Improve documentation of pdumper; minor code cleanupEli Zaretskii2019-01-161-50/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/emacs.c (usage_message): Add the --dump-file option. (string_starts_with_p, find_argument): Functions removed; use 'argmatch' instead. (PDUMP_FILE_ARG): Macro removed; use literal strings instead, as with other command-line options. Use HAVE_PDUMPER for cpp conditionals which used PDUMP_FILE_ARG. (load_pdump, main): Use 'argmatch' for "--dump-file" and "--temacs" arguments, thus supporting the "-dump-file" and "-temacs" variants, for consistency with other options. (main): Remove the extra fatal error for using --dump-file in unexec'ed Emacs: load_pdump does that anyway. (standard_args): Add --dump-file and --temacs, with appropriate priorities. * etc/NEWS: Expand on the pdumper support. * doc/emacs/cmdargs.texi (Initial Options): Document the '--dump-file' command-line option.

Also, simplify bignum memory management, fixing some unlikely leaks. This patch improved the performance of (+ 2 2) by a factor of ten on a simple microbenchmark computing (+ x 2), byte-compiled, with x a local variable initialized to 2 via means the byte compiler could not predict: performance improved from 135 to 13 ns. The platform was Fedora 28 x86-64, AMD Phenom II X4 910e. Performance also improved 0.6% on ‘make compile-always’. * src/bignum.c (init_bignum_once): New function. * src/emacs.c (main): Use it. * src/bignum.c (mpz): New global var. (make_integer_mpz): Rename from make_integer. All uses changed. * src/bignum.c (double_to_bignum, make_bignum_bits) (make_bignum, make_bigint, make_biguint, make_integer_mpz): * src/data.c (bignum_arith_driver, Frem, Flogcount, Fash) (expt_integer, Fadd1, Fsub1, Flognot): * src/floatfns.c (Fabs, rounding_driver, rounddiv_q): * src/fns.c (Fnthcdr): Use mpz rather than mpz_initting and mpz_clearing private temporaries. * src/bignum.h (bignum_integer): New function. * src/data.c (Frem, Fmod, Fash, expt_integer): * src/floatfns.c (rounding_driver): Use it to simplify code. * src/data.c (FIXNUMS_FIT_IN_LONG, free_mpz_value): Remove.

(floatop_arith_driver, arith_driver): Simplify by assuming NARGS is at least 2. All callers changed. (float_arith_driver): New arg, containing the partly converted value of the next arg. Reorder args for consistency. All uses changed. (bignum_arith_driver): New function. (arith_driver): Use it. Do fixnum-only integer calculations in intmax_t instead of mpz_t, when they fit. Break out mpz_t calculations into bignum_arith_driver. (Fquo): Use floatop_arith_driver instead of float_arith_driver, since the op is known to be valid. (Flogcount, Fash): Simplify by coalescing bignum and fixnum code. (Fadd1, Fsub1): Simplify by using make_int.

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.
* | Avoid libgmp aborts by imposing limitsPaul Eggert2018-08-211-34/+0

The numeric limit is large and platform-dependent; with 64-bit GMP 6.1.2 it is around 2**2**37. Work around the problem by refusing to call libgmp functions with arguments that would cause an abort. With luck libgmp will have a better way to do this in the future. Also, introduce a variable integer-width that lets the user control how large bignums can be. This currently defaults to 2**16, i.e., it allows bignums up to 2**2**16. This should be enough for ordinary computation, and should help Emacs to avoid thrashing or hanging. Problem noted by Pip Cet (Bug#32463#71). * doc/lispref/numbers.texi, etc/NEWS: Document recent bignum changes, including this one. Improve documentation for bitwise operations, in the light of bignums. * src/alloc.c (make_number): Enforce integer-width. (integer_overflow): New function. (xrealloc_for_gmp, xfree_for_gmp): Move here from emacs.c, as it's memory allocation. (init_alloc): Initialize GMP here, rather than in emacs.c. (integer_width): New var. * src/data.c (GMP_NLIMBS_MAX, NLIMBS_LIMIT): New constants. (emacs_mpz_size, emacs_mpz_mul) (emacs_mpz_mul_2exp, emacs_mpz_pow_ui): New functions. (arith_driver, Fash, expt_integer): Use them. (expt_integer): New function, containing integer code that was out of place in floatfns.c. (check_bignum_size, xmalloc_for_gmp): Remove. * src/emacs.c (main): Do not initialize GMP here. * src/floatfns.c (Fexpt): Use expt_integer, which now contains integer code moved from here. * src/lisp.h (GMP_NUMB_BITS): Define if gmp.h doesn’t.
* | Reject outlandishly-wide bignumsPaul Eggert2018-08-161-3/+21
| | | | | | | | | | | | | | | | | | Do not allow bignums that are so wide that their log base 2 might not fit into a fixnum, as this will cause problems elsewhere. We already have a similar limitation for bool-vectors. * src/emacs.c (check_bignum_size, xmalloc_for_gmp): New function. (xrealloc_for_gmp): Check for too-large bignum. (main): Use xmalloc_for_gmp.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With --[bg-]daemon and Type=forking, systemd will only consider the daemon to have fully started up once the original process exits, and will wait until then to start units depending on the Emacs service. To get the same functionality with --fg-daemon, use Type=notify instead of Type=simple and explicitly send a readiness notification to systemd at the point where the forked process would in --bg-daemon mode notify its parent process and cause it to exit. Similarly, notify systemd at the beginning of the shutdown process as well. (Both of these calls are successful no-ops if emacs was not started by systemd.) * etc/emacs.service: Update Type. * src/emacs.c (daemon-initialized) [HAVE_LIBSYSTEMD]: * src/emacs.c (kill-emacs) [HAVE_LIBSYSTEMD]: Call sd_notify().

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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
