* | Unbreak echoingDaniel Colascione2018-06-091-1/+5
| | | | | | | | * src/keyboard.c (read_key_sequence): Don't echo_truncate the first time.
* | Fix pointer misuse in JSON parserPaul Eggert2018-06-091-32/+28
| | | | | | | | | | | | | | | | | | * src/json.c (lisp_to_json_toplevel_1): Fix pointer misuse not caught by C type checking (json_t ** converted to void * where the program expected json_t *). Bug caught on Fedora 28 x86-64 via './configure CFLAGS="-g3 -O2 -fsanitize=address" CANNOT_DUMP=yes'. Avoid similar problems in the future by rewriting to use json_t * instead of json_t **.
* | Correctly set last_nonmenu_event when replayingDaniel Colascione2018-06-091-3/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | read_key_sequence can, in various circumstances, play back recorded events. Make sure that we set last_nonmenu_event as if we weren't replaying. Without this change, we leave last_nonmenu_event set to whatever it was before we started replaying, leading to spurious random keymap menu prompts appearing after reading terminal control sequences, the translation of which sometimes causes event replays. * src/keyboard.c: (grow_bool_vector): New function (read_key_sequence): Remember menu event history per-event.
* | Add debug facility for formatting in rr sessionsDaniel Colascione2018-06-092-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | The existing debug print commands don't work in rr, since they touch stderr. The new xfmt command just calls Fformat and doesn't touch the stdio streams. * src/.gdbinit: (xfmt): New GDB command. * src/print.c: (debug_format): New function.
* | Fix read buffer overrun on overflowed integersPaul Eggert2018-06-091-2/+2
| | | | | | | | | | | | | | * src/lread.c (read_integer): Fix off-by-1 buffer overrun introduced in 2018-04-17T23:23:16Z!eggert@cs.ucla.edu. The bug could occur when Emacs read radixed integers containing more than 100 digits. Bug caught by AddressSanitizer.
* | Make error checking for thread functions stricter.Philipp Stephani2018-06-092-23/+79
| | | | | | | | | | | | | | | | | | | | | | | | * src/systhread.c (sys_thread_create): Change return type to bool. Check for errors returned by pthread_attr_setstacksize and pthread_attr_destroy. (sys_mutex_init): Abort on errors. Enable mutex checks when checking is enabled. (sys_cond_init): Abort on errors. (sys_mutex_lock, sys_mutex_unlock, sys_cond_wait) (sys_cond_signal, sys_cond_broadcast, sys_cond_destroy): Check for errors in debug mode.
* | Remove AddressSanitizer bug workaroundPaul Eggert2018-06-082-6/+6
| | | | | | | | | | | | | | | | | | This workaround no longer appears to be needed. * src/alloc.c (USE_ALIGNED_ALLOC): Don’t leave undefined merely because ADDRESS_SANITIZER is defined, as that bug in -fsanitize=address appears to have been fixed. See: https://github.com/google/sanitizers/issues/337 * src/conf_post.h (vfork): Improve comment.
* | Fix formatting in the face filter changeDaniel Colascione2018-06-081-22/+31
| | | | | | | | | | | | * src/xfaces.c: (evaluate_face_filter,filter_face_ref) (merge_face_ref,syms_of_xfaces): Fix comments, formatting.
* | Port alignment verification to x86 --with-wide-intPaul Eggert2018-06-081-4/+4
| | | | | | | | | | | | | | | | | | Problem reported by Eli Zaretskii in: https://lists.gnu.org/r/emacs-devel/2018-06/msg00238.html * src/lisp.h (struct Lisp_Symbol, union vectorlike_header) (struct Lisp_Cons, struct Lisp_String): Do not check alignment if !USE_LSB_TAG, as alignment is needed only if we are tagging the low-order bits.
* | ; Tiny tpyo fixMichal Nazarewicz2018-06-081-1/+0
| | | | | | | | | | * src/xfaces.c (face-remapping-alist): remove an empty ‘(3)’ introduced in a docstring by mistake.
* | Add support for per-window face remappingDaniel Colascione2018-06-078-123/+286
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend face specifications to support the notion of filtering to a specific context and add a filter that limits a face specification to windows having a certain parameter. * src/xfaces.c: (evaluate_face_filter,filter_face_ref): New functions. (merge_face_ref): Ignore filtered face specifications.

* | Fit kill_buffer_xwidgets into 80Paul Eggert2018-06-071-10/+10
| | | | | | | | | | * src/xwidget.c (kill_buffer_xwidgets): Reindent and use C99 style to fit in 80 columns.
* | Minor cleanup of save_excursion_restorePaul Eggert2018-06-071-24/+17
| | | | | | | | | | * src/editfns.c (save_excursion_restore): Use clearer names for locals. Free earlier, removing the need for a label and goto.
* | New function record_unwind_protect_excursionPaul Eggert2018-06-077-9/+15
| | | | | | | | | | | | | | | | | | | | | | This simplifies callers a bit, and will simplify future changes. * src/eval.c (record_unwind_protect_excursion): New function. * src/buffer.c (Fkill_buffer): * src/bytecode.c (exec_byte_code): * src/editfns.c (Fsave_excursion, Freplace_buffer_contents): * src/lread.c (readevalloop, Feval_buffer): * src/window.c (scroll_command): Use it.

* | Fix ftfont_open2 failure cleanupPaul Eggert2018-06-071-2/+5
| | | | | | | | | | * src/ftfont.c (ftfont_open2): Don’t increment counter if failing. Avoid use-after-free once the increment bug is fixed.
* | Don’t over-align if WIDE_EMACS_INTPaul Eggert2018-06-071-5/+11
| | | | | | | | | | | | | | * src/lisp.h (GCALIGNED_UNION): New macro. (struct Lisp_Symbol, union vectorlike_header) (struct Lisp_Cons, struct Lisp_String): Use it to avoid possible over-alignment if !USE_LSB_TAG.
* | Fix GC-related commentaryPaul Eggert2018-06-071-9/+12
| | | | | | | | | | | | | | * src/lisp.h: USE_STACK_LISP_OBJECTS is no longer experimental. Also, remove confusion about scope vs lifetime. And say that stack-allocated strings should not be given text properties.
* | Accept plists when serializing and parsing JSONJoão Távora2018-06-071-24/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * doc/lispref/text.texi (Parsing JSON): Mention plist support. * src/json.c (lisp_to_json_toplevel_1): Serialize plists to json.

| | | | | | | | | | | | | | | | | | | | | | | | | | * src/fileio.c (Fexpand_file_name): Don't build multibyte strings from unibyte non-ASCII strings when NAME and DEFAULT_DIRECTORY have different multibyteness, as this adds bytes to the byte sequence, and in some situations, e.g., when the home directory includes non-ASCII characters, can fail file APIs. (Bug#30755) * lisp/startup.el (normal-top-level): Make sure default-directory is set to a multibyte string when decoded on MS-Windows.

| | | | | | | | | | | | | | | | | | | | * src/font.c (font_open_entity): Fail after 15 iterations through the loop that looks for a font whose average_width and height are both positive. This avoids infinite loops for fonts that, e.g., report average_width of zero for any possible size we try. (Bug#31316) (cherry picked from commit e2879c1f837059335af89022b2a9ac9bc861e96d)

(Bug#30582) Reset the line_number_produced_p flag before laying out the glyph row. (x_produce_glyphs): Use the line_number_produced_p flag to decide whether to offset the X coordinate due to line-number display. Use the tab_offset member to restore the original TAB width for alignment purposes. (move_it_in_display_line_to): Don't produce line numbers when moving in hscrolled window to the left of first_visible_x. (maybe_produce_line_number): Set the line_number_produced_p flag. (Bug#30584) * src/term.c (produce_glyphs): Correct TAB width only when line_number_produced_p flag is set. (cherry picked from commit 1ac190553886ff20817d3dd218464e2fc6f9e42a)
| * Fix wait_reading_process_output wait_proc hangMatthias Dahl2018-06-022-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/process.c (read_process_output): Track bytes read from a process. (wait_reading_process_output): If called recursively through timers and/or process filters via accept-process-output, it is possible that the output of wait_proc has already been read by one of those recursive calls, leaving the original call hanging forever if no further output arrives through that fd and no timeout has been set. Fix that by using the process read accounting to keep track of how many bytes have been read and use that as a condition to break out of the infinite loop and return to the caller as well as to calculate the proper return value (if a wait_proc is given that is). * src/process.h (struct Lisp_Process): Add nbytes_read to track bytes read from a process. (cherry picked from commit 4ba32858d61eee16f17b51aca01c15211a0912f8)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/dispnew.c (buffer_posn_from_coords): Improve commentary. * src/xdisp.c (move_it_in_display_line_to): Don't exit the loop under truncate-lines if the glyph at TO_CHARPOS was not yet produced. This avoids bailing out too early when we are at TO_CHARPOS, but didn't yet produce glyphs for that buffer position, because the last call to PRODUCE_GLYPHS at this position was for an object other than the buffer. For further details, see http://lists.gnu.org/archive/html/emacs-devel/2018-01/msg00537.html. (cherry picked from commit c0154ac7c3423f68d8f3a2e85a756c9759219039)
