In the signal handler for the signal SIGWINCH tty_term_resize, we call
tty_dpy_invalidate function. In this function, we change the screen_size
and other critical fields.
While the process is executing the function tty_dpy_flush, and another
SIGWINCH occurs, then the screen_size is changed. And tty_dpy_flush will
access invalid memory which leads to coredump.
In the signal hander of SIGWINCH, we only need to set the flag
complete_refresh.
* fix crash on "https://support.apple.com/kb/HT208050"
* add missing initializer (stupid oversight)
* fix bogus overflow test (another nasty bug waiting to bite)
We desperately need warnings or idioms against such stupid errors.
Using constructors for all locally defined structures seems advidsable,
* use complete list of internal commands
* use tcl specific word parser
* fix quoted and braced string parsers
* improve variable colorizer
* add custom cases in probe function
* add `ustr_match_str`
* fix bug in `eb_free` where log and style buffers were not freed
* free minibuffer history list
* free css symbols when finalizing the graphics html viewer
* add `CLANG_C_TYPES` flag for generic C types
* add `CLANG_C_KEYWORDS` flag for generic C keywords
* add `CLANG_T_TYPES` flag for generic `xxx_t` types
* more explicit regex testing
* support for `u`, `U` and `u64` encoding prefixes
* improve comment detection in diff output for js and c3
* change `get_c_identifier` API for consistency
* add `is_c_identifier_start()` and `is_c_identifier_part()`
* move `qe_haslower` to **util.c**
* update C2 language keyword and type lists
* improve Pike colorizer
- rename `edit_new` as `qe_new_window`
- report error in `qe_new_buffer` and `qe_new_window` upon failure
- rename `qe_find_buffer_file` as `qe_find_buffer_filename`
- rename `read_charset` as `qe_parse_charset`
- reset yank buffer references in `eb_clear()`
- make `qe_init()` return error code and abort upon error
- add debug info in asan, msan and ubsan builds
- avoid function call in `qe_unaccent` for ASCII chars
- fix `find_ligature` return type to detect simple ligatures with a simple test
- fix crash bug in `expand_ligature`, behavior was bogus anyway.
- add clipboard handling method `2` using `pbcopy` and `pbpaste` on macOS
- use this method by default when running under macOS from the Apple
Terminal. The last kill is copied to the system clipboard upon losing
focus and the clipboard contents is retrieved and copied to a new kill
buffer upon gaining focus.
* Fix `put_status`/`put_error` behavior
- use `put_error` instead of `put_status` for command errors
- prevent status message output to console during initialization
- use `put_error` for side effects in command errors
- add `&` prefix in status messages to force screen flush
- flush screen in `qe_display()`, remove redundant calls to `dpy_flush`
- fix gcc compilation errors and warnings
- remove most references to `global_screen`
- free font cache before closing the screen
- prevent mouse handling upon focus detection
* drop CI on macos-12
Mouse:
- add `shift` state in all mouse events
- pass `QEmacsState *qs` to `qe_mouse_event`
- support non drag mouse events with `-m:2` command line option
- dragging beyond window borders generates scrolling events
(should autorepeat, should have menu line at the top for scrolling up)
- cancel active search on mouse_goto
- do not mouse activate window if current active window is modal (popup or
minibuf)
- handle double and triple click: select by words or lines
- handle shift click: extend selection
- add `EditState::mouse_down_offset` for initial dragging buffer offset
- pass `QEEvent *ev` to `mouse_goto()` handlers
events:
- add synthetic key events: QUIT CLOSE EXIT
- use synthetic events for GUI interaction (no longer simulate keystrokes)
tty:
- fix large OSC sequence support for terminal clipboard retrieval
Multicursor:
- use new `QECursor` for multicursor local states
- reallocate `multi_cursor` array in chunks
misc:
- add `eb_peekc(EditBuffer *b, int offset)`
- boolean cmdline options no longer require an argument, true if none provided
- int cmdline options either require an argument (CMD_LINE_INT_ARG) or take an
optional argument, value is incremented if argument is not provided.
