* Fix unwarranted point movement after C-gEli Zaretskii2021-08-15
| | | | | | | | | | | | | | | | | When the same buffer is displayed in more than one window, redisplay temporarily moves point to the window-point when it works on non-selected windows. If we allow C-g to quit out of redisplay_window in this situation, point will appear to have moved to the window-point of that non-selected window, which is unwarranted. These changes prevent quitting in strategic places, so that we never quit out of redisplay_window. * src/xdisp.c (run_window_scroll_functions): Prevent quitting while running window-scroll-functions, so that we don't quit out of redisplay_window with temporarily moved point. (redisplay_window): While redisplaying the mode line, prevent quitting, to avoid exiting while point is temporarily moved. (decode_mode_spec): Use safe_call1 instead of call1, to trap any errors instead of letting them throw out of redisplay. (Bug#44448)

* Fix problem where an error would change standard-outputLars Ingebrigtsen2021-08-13
| | | | | | * src/keyboard.c (cmd_error): Don't set standard-output/standard-input (bug#30529). Instead bind them temporarily while handling the error.
* Allow using XLFD font names with dashes in the family nameLars Ingebrigtsen2021-08-11
| | | | | | | | * src/font.c (font_parse_xlfd_1): Rename from font_parse_xlfd to allow calling twice from a wrapper (bug#35816). (font_parse_xlfd): Wrapper function -- first try to parse in the normal way, and then try to guess that the hyphenated bits are in the family name.

* Simplify macOS drawing codeAlan Third2021-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert EmacsSurface into a CALayer subclass so we can use the built-in relationships. Also simplify the macOS versioning code. This will result in more warnings on older versions of macOS but makes reading the code easier. * configure.ac: Add QuartzCore framework. * src/nsterm.h (NS_DRAW_TO_BUFFER): Remove define and all references. (EmacsSurface, EmacsLayer): Rename EmacsSurface to EmacsLayer and modify the definition to fit the new function. * src/nsterm.m (ns_update_begin): (ns_update_end): (ns_focus): (ns_unfocus): Use the new overridden lockFocus and unlockFocus and simplify the frame management. ([EmacsView dealloc]): ([EmacsView viewDidResize:]):Don't explicitly release surfaces.

* Convert fringe bitmaps to vectors on NS portAlan Third2021-07-26
| | | | | | | | | | | | | | | Unfortunately *step doesn't support masks for bitmap images so changing the colors of fringe bitmaps is awkward. We can work around this by converting the bitmap into an NSBezierPath and drawing it in the required color. * src/nsterm.m (ns_define_fringe_bitmap): (ns_destroy_fringe_bitmap): New functions (ns_draw_fringe_bitmap): Display the NSBezierPath. * src/nsimage.m ([EmacsImage initFromXBM:width:height:fg:bg:reverseBytes:]): Remove variable that's there to allow us to easily modify the XBM colors. ([EmacsImage setXBMColor:]): Remove method.

| | | | | | | * src/nsterm.m (ns_set_offset): Unify the two branches into one, most of the code is the same. (ns_set_window_size): Use the provided tools to calculate the window size instead of doing it ourselves.

* Fix image crash on macOS (bug#49688)Alan Third2021-07-26
| | | | | * src/nsimage.m ([EmacsImage allocInitFromFile:]): Use isValid to check whether the image is valid instead of generating a tiff.
* Fix compilation of xftfont.c with old fontconfigEli Zaretskii2021-07-25
