* | Don’t trust st_size when scanning file head+tailPaul Eggert2025-07-131-15/+12
| | | | | | | | | | | | | | * src/fileio.c (Finsert_file_contents): Do not look at st_size when scanning the file’s head and tail for a coding system comment. Instead, just use read and SEEK_END and don’t worry if the latter fails. st_size and lseek might not work in a /proc file system.
* | copy-file no longer trusts st_sizePaul Eggert2025-07-131-42/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In copy-file, do not trust st_size, since it might change as we run, or we might be in a /proc system where it is unreliable anyway. Also, fix some other unlikely copy-file bugs while we’re here. * src/fileio.c (Fcopy_file): Use O_TRUNC when opening a destination that already exists. This saves us the trouble of having to call ftruncate with a possibly-bogus st_size; the old motivation for using ftruncate is no longer compelling. Do not assume ptrdiff_t is as wide as ssize_t; although this is true on all known platforms, it’s easy to not assume it. Don’t trust st_size. Prefer SSIZE_MAX to TYPE_MAXIMUM (ssize_t). Always read+write, regardless of whether copy_file_range failed.
* | READ_BUF_SIZE → sizeof read_bufPaul Eggert2025-07-131-2/+2
| | | | | | | | | | | | * src/fileio.c (Finsert_file_contents): Minor refactoring. This should help future patches which distinguish read_buf’s size from other uses of READ_BUF_SIZE which may change.
* | insert-file-contents errno confusionPaul Eggert2025-07-131-11/+15
| | | | | | | | | | | | * src/fileio.c (read_non_regular): Return negation of errno on failure, instead of -1. (Finsert_file_contents): Signal with correct errno when a read fails.
* | Avoid crashes when profiling multi-threaded Lisp (bug#76970)Pip Cet2025-07-121-1/+5
| | | | | | | | | | * src/eval.c (backtrace_p): Check 'current_thread' before dereferencing it.

* | Move CSS into the SVG wrapperAlan Third2025-07-101-30/+26
| | | | | | | | | | | | | | | | This allows CSS to be used with librsvg < 2.48. * src/image.c (svg_load_image): Move CSS construction and include "color". Also append the CSS passed in by the user rather than replacing it.
* | Change foreground color handling for SVG files (bug#77841)Alan Third2025-07-101-1/+1

* | Unintern Qget_file_char and Qget_emacs_mule_file_charMattias Engdegård2025-07-101-3/+10
| | | | | | | | | | | | | | | | These symbols are used in the reader as special constants and can't be passed from Lisp (Emacs would crash). * src/lread.c (syms_of_lread): Unintern. (init_source): Use BASE_EQ.
* | Speed up low-level parts of the reader and refactorMattias Engdegård2025-07-101-392/+415
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inspect the given 'readcharfun' source once, before using it, instead of for each character read. This moves a bunch of branches away from the critical path, with separate functions for different source types. Replace some preprocessor macros with functions. * src/lread.c (READCHAR, UNREAD, READCHAR_REPORT_MULTIBYTE) (FROM_FILE_P): Remove; use corresponding functions instead. All callers adapted. (source_t): New struct that takes the place of the `readcharfun` and `readbyte` arguments in many places. (init_source) (source_buffer_get, source_buffer_unget) (source_marker_get, source_marker_unget) (source_string_get, source_string_unget) (source_file_get, source_file_unget) (source_function_get, source_function_unget) (from_file_p, unreadbyte_from_file): New. (readbyte_from_stdio): Replace `readbyte_from_file`. (readchar, unreadchar): Rewrite. (lisp_file_lexical_cookie, readevalloop, read_internal_start): Create a source_t for use during reading. All signatures and functions called adapted. (read_char_escape): Remove check for an error that can no longer occur.

* | Nativecomp don't materialize non-materializable objects (bug#78606)Andrea Corallo2025-07-091-19/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The native compiler should not try to generate in rendered code immediate floats produced by the constrain on the '=' operator. * test/src/comp-tests.el (comp-test-78606-1): Add test. * test/src/comp-resources/comp-test-funcs.el (comp-test-78606-1-f): New function. * src/comp.c (emit_mvar_rval): Check if an immediate is materializable. * lisp/emacs-lisp/comp.el (comp-ctxt): Add 'non-materializable-objs-h' slot.

* | Fix crashes when "emacsclient -nw" frames are suspended (bug#78980)Pip Cet2025-07-091-3/+3
| | | | | | | | | | * src/frame.c (frame_redisplay_p): Start loop with 'f', not its parent frame. Simplify return expression.
* | print_error_message: Handle user-error to the echo area speciallySean Whitton2025-07-091-0/+13
| | | | | | | | | | | | * src/print.c (print_error_message): For a user-error that is to be printed to the echo area, use message3 in order to preserve fontification.
* | Handle invalid frame_or_window slots in tty input events (Bug#78966)Martin Rudalics2025-07-092-10/+34
| | | | | | | | | | | | | | | | | | | | | | * src/frame.c (make_terminal_frame): Initialize terminal's top_frame slot if it has not been set up yet (Bug#78966). * src/keyboard.c (kbd_buffer_get_event): Do not assume that the event's frame_or_window slot always produces a valid frame (Bug#78966). (tty_read_avail_input): Try to make sure that the input event we create has a valid frame_or_window slot (Bug#78966). Add assertion to that purpose.
* | Add a synchronous way to get parser change ranges (bug#78402)Yuan Fu2025-07-081-10/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit only adds the new function, the fix for the bug is in the next commit. * doc/lispref/parsing.texi (Using Parser): Add docs. * lisp/treesit.el (treesit): Add shortdoc. * src/treesit.c (treesit_get_affected_ranges): New function extracted from treesit_call_after_change_functions. (treesit_call_after_change_functions): Extract out. (treesit_ensure_parsed): Return affected regions. (Ftreesit_parser_changed_regions): New function that returns the affected regions.

* | Refactor buffering code in the Lisp readerMattias Engdegård2025-07-071-71/+77
| | | | | | | | | | | | | | | | | | | | | | Abstract the buffering in the reader with a struct and plain functions instead of rather unhygienic preprocessor macros. * src/lread.c (READ_AND_BUFFER, INVALID_SYNTAX_WITH_BUFFER): Removed, replaced with... (readbuf_t, readbuf_grow, add_char_to_buffer, read_and_buffer) (invalid_syntax_with_buffer): ...these new functions and struct. (read0): Use new code instead of old preprocessor macros.

* | process-attributes uses CLOCK_BOOTTIME for uptimePaul Eggert2025-06-171-41/+13
| | | | | | | | | | | | | | * src/sysdep.c (get_host_uptime) [GNU_LINUX || CYGWIN || __ANDROID__]: New function, replacing get_host_boot_time. Use CLOCK_BOOTTIME instead of inspecting /proc/stat. All callers changed. This should be an even better way to fix Bug#63496.
* | process-attributes uses /proc/stat for boot timePaul Eggert2025-06-171-2/+43
| | | | | | | | | | | | | | | | | | | | | | | | With a Linux kernel, use /proc/stat rather than get_boot_time to get boot time, since when Emacs is running in a container we want the underlying host boot time, not the container boot time. This should be a better way to fix Bug#63496. * src/sysdep.c: Do not include boot-time.h. (get_host_boot_time) [GNU_LINUX || CYGWIN || __ANDROID__]: New function. (system_process_attributes) [GNU_LINUX || CYGWIN || __ANDROID__]: Use it instead of get_boot_time.

| | | | | | | | | | | | | | * src/xdisp.c (try_scrolling): Don't loop when the partially-visible cursor line is at the top of the window. This looping are pointless, and just makes redisplay slow for no reason. (Bug#78766)
* | process-attributes now uses get_boot_timePaul Eggert2025-06-151-36/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed this issue while looking into Bug#63496. GNU Emacs does not infer the boot time consistently on GNU/Linux and similar platforms: android_notifications_notify_1 and get_boot_sec use Gnulib’s boot-time module, but process-attributes has idiosyncratic code that evidently predates that module. The idiosyncratic code returns an unstable etime, which is a minor bug. Simplify process-attributes by just using Gnulib. This returns a stable etime. It may also fix Bug#63496; if not, we can fix Gnulib later. * src/sysdep.c: Include <boot-time.h>. (get_up_time) [GNU_LINUX || CYGWIN || __ANDROID__]: Remove. (system_process_attributes) [GNU_LINUX || CYGWIN || __ANDROID__]: Use get_boot_time instead of get_up_time.
