Changes to Readline + +a. Added a guard to prevent nested macros from causing an infinite expansion + loop. + +b. Instead of allocating enough history list entries to hold the maximum list + size, cap the number allocated initially. + +c. Added a strategy to avoid allocating huge amounts of memory if a block of + history entries without timestamps occurs after a block with timestamps. + +d. Added support for keyboard timeouts when an ESC character is the last + character in a macro. + +e. There are several performance improvements when in a UTF-8 locale. + +f. Readline does a better job of preserving the original set of blocked + signals when using pselect() to wait for input. + +g. Fixed a bug that caused multibyte characters in macros to be mishandled. + +h. Fixed several bugs in the code that calculates line breaks when expanding + prompts that span several lines, contain multibyte characters, and contain + invisible character seqeuences. + +i. Fixed several bugs in cursor positioning when displaying lines with prompts + containing invisible characters and multibyte characters. + +j. When performing case-insensitive completion, Readline no longer sorts the + list of matches unless directed to do so. + +k. Fixed a problem with key sequences ending with a backslash. + +l. Fixed out-of-bounds and free memory read errors found via fuzzing. + +m. Fixed several cases where the mark was set to an invalid value. + +n. Fixed a problem with the case-changing operators in the case where the + lower and upper case versions of a character do not have the same number + of bytes. + +o. Handle incremental and non-incremental search character reads returning EOF. + +p. Handle the case where a failing readline command at the end of a multi-key + sequence could be misinterpreted. + +q. The history library now prints a meaningful error message if the history + file isn't a regular file. + +r. Fixed a problem with vi-mode redo (`.') on a command when trying to replace + a multibyte character. + +s. The key binding code now attempts to remove a keymap if a key unbinding + leaves it empty. + +t. Fixed a line-wrapping issue that caused problems for some terminal + emulators. + +u. If there is a key bound to the tty's VDISCARD special character, readline + disables VDISCARD while it is active. + +v. Fixed a problem with exiting bracketed paste mode on terminals that assume + the bracketed paste mode character sequence contains visible characters. + +w. Fixed a bug that could cause a key binding command to refer to an + uninitialized variable. + +x. Added more UTF-8-specific versions of multibyte functions, and optimized + existing functions if the current locale uses UTF-8 encoding. + +y. Fixed a problem with bracketed-paste inserting more than one character and + interacting with other readline functions. + +z. Fixed a bug that caused the history library to attempt to append a history + line to a non-existent history entry. + +aa. If using bracketed paste mode, output a newline after the \r that is the + last character of the mode disable string to avoid overwriting output. + +bb. Fixes to the vi-mode `b', `B', `w', `W', `e', and `E' commands to better + handle multibyte characters. + +cc. Fixed a redisplay problem that caused an extra newline to be generated on + accept-line when the line length is exactly the screenwidth. + +dd. Fixed a bug with adding multibyte characters to an incremental search + string. + +ee. Fixed a bug with redoing text insertions in vi mode. + +ff. Fixed a bug with pasting text into an incremental search string if bracketed + paste mode is enabled. ESC cannot be one of the incremental search + terminator characters for this to work. + +gg. Fixed a bug with anchored search patterns when performing searches in vi + mode. + +2. New Features in Readline + +a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as + Posix specifies (uses fnmatch(3) if available). + +b. There are new `next-screen-line' and `previous-screen-line' bindable + commands, which move the cursor to the same column in the next, or previous, + physical line, respectively. + +c. There are default key bindings for control-arrow-key key combinations. + +d. A negative argument (-N) to `quoted-insert' means to insert the next N + characters using quoted-insert. + +e. New public function: rl_check_signals(), which allows applications to + respond to signals that readline catches while waiting for input using + a custom read function. + +f. There is new support for conditionally testing the readline version in an + inputrc file, with a full set of arithmetic comparison operators available. + +g. There is a simple variable comparison facility available for use within an + inputrc file. Allowable operators are equality and inequality; string + variables may be compared to a value; boolean variables must be compared to + either `on' or `off'; variable names are separated from the operator by + whitespace. + +h. The history expansion library now understands command and process + substitution and extended globbing and allows them to appear anywhere in a + word. + +i. The history library has a new variable that allows applications to set the + initial quoting state, so quoting state can be inherited from a previous + line. + +j. Readline now allows application-defined keymap names; there is a new public + function, rl_set_keymap_name(), to do that. + +k. The "Insert" keypad key, if available, now puts readline into overwrite + mode. + +------------------------------------------------------------------------------- This document details the changes between this version, readline-7.0, and the previous version, readline-6.3. diff --git a/readline/ChangeLog.gdb b/readline/ChangeLog.gdb index 6937880..982ef7b 100644 --- a/readline/ChangeLog.gdb +++ b/readline/ChangeLog.gdb @@ -1,5 +1,9 @@ 2019-08-12 Tom Tromey <tom@tromey.com> + * Imported readline 8.0. + +2019-08-12 Tom Tromey <tom@tromey.com> + * Makefile.in (xfree.o): Don't depend on readline.h. * xfree.c (xfree): Remove gdb workaround. * xmalloc.h (xfree): Remove #define. diff --git a/readline/INSTALL b/readline/INSTALL index e1a92d3..afb4d53 100644 --- a/readline/INSTALL +++ b/readline/INSTALL @@ -1,7 +1,7 @@ Basic Installation ================== -These are installation instructions for Readline-7.0. +These are installation instructions for Readline-8.0.
