(P) +* If a line began with a tabulator and another tabulator was inserted with + the cursor located on the first tabulator, the display was not updated + appropriately since the last release (Bugreport by Matthew Fischer). (P) +* Fixed a segmentation fault that occured in multibyte locales when operation + was continued after vi had been stopped by ^Z, with the cursor positioned + in a line longer than the terminal width as the last line of the current + screen. +* Made multicolumn characters work in lines longer than the screen width in + visual mode (Bugreport by Matthew Fischer). +* Made it work for Big5 locales (Patches by Matthew Fischer). +* Fixed a problem with the 'r' command in EUC-JP and Big5 locales (Bugreport + by Matthew Fischer). +* The insertion of multicolumn characters and tab characters in multibyte + locales now works with terminals that have the 'ic' but no 'im' termcap + capability (Bugreport by Matthew Fischer). +* The argument to the -w option is correctly recognized now. +* If the SHELL environment variable is set to the empty string, it is now + ignored. +* A non-null exit status is now returned if a file could not be opened, if + an invalid address is given for a command, or if a tag is not found. +* If the match for a substitution is of length zero, a line overflow is + now avoided when compiled with the 'UNIX(R) Regular Expression Library'. +* When moving left while the cursor is positioned over a multicolumn + character at the end of the line, the bell is rung now (Bugreport by + Matthew Fischer). +* When moving up or down to a row with different column arrangement while + the cursor is positioned over a multicolumn character, the leftmost + character above the original position is chosen in the new row. +* If both the -t and the -c option are given, the -t option is now + processed first, i.e. the command is executed at the position where + the tag was found. +* The -w option now also sets the scroll size for the 'z' command. +* When the name of a nonexisting file is given with the 'edit' ex command, + the command now succeeds and prints a "[New file]" message. +* If standard output is not a terminal, no '\r' is written at the end of + printed lines anymore. +* The 'source' ex command now works if command input comes from a pipe or + regular file. +* Ex does not exit on errors immediately anymore if standard input is not + a terminal but a pipe or regular file. +* The 'substitute' ex command can now be abbreviated as 'sub', 'subst' etc. +* A new version of mapmalloc.c that is derived from Unix 7th Edition code + has been introduced. +* If the 'next!' ex command is given and the autowrite option is set, the + current file is not written anymore. + +Release 1/19/05 +* The last release erroneously made 'X' work like 'x' in visual mode. It now + deletes the character before the cursor again as documented (Bugreport by + Matthew Fischer). (P) +* When a multicolumn character was replaced by another multicolumn character + in insert mode, the display was not updated appropriately with terminals + other than xterm. +* Various rendering errors happened with multicolumn characters if they + started at an even column (counting from 1 upwards). +* When a multicolumn character was inserted and then replaced, the visual + screen representation was sometimes not updated accordingly. +* Undoing the replacement of a multicolumn character by a singlecolumn + character twice made the singlecolumn character invisible. +* The 'cw' visual command with a multibyte character as last character of + the affected word located at the end of the line left garbage bytes past + the end of the new text. +* Visual 'U' followed by 'u' lead to garbage on the screen when multibyte + characters were present on the changed line. +* The position of '$' when changing text was fixed for cases where the first + changed character had multiple columns but the last one had not. +* The handling of multicolumn characters was fixed for terminals without the + IM (insert mode) capability. It is unlikely that such terminals actually + exist, but vi will use the corresponding code for open mode if a termcap + entry is not available. +* When an illegal multibyte sequence is entered in vi insert mode, no garbage + bytes are generated anymore when the insert mode is left. +* The '\u', '\l', '\U', and '\L' substitution sequences work with multibyte + characters now. +* Handle character case conversions with the '~' vi command correctly if the + length of the converted multibyte sequence is smaller than the original one. +* Multibyte sequences that correspond to an unprintable character are now + printed as multiple octal escape sequences. +* Pressing the ^U (kill) character in insert mode with a multibyte character + at the beginning of an insertion at the start of a line sometimes positioned + the cursor at weird locations since the last revision. +* Fixed an old vi bug: If a vi command that yanked or deleted part of a line + was followed by an ex command that also yanked or deleted some text, a + following 'p' vi command pasted the text affected by the former vi command. + It now pastes the text of the last yank or delete even if that was an ex + command. +* Some build fixes for diet libc have been made. + +Release 12/2/04 +* Support for multibyte character locales was added. +* The code has been converted to ANSI C, and support for pre-POSIX systems has + been dropped. +* When the end of the current line consists of blank characters and the 'w' + visual command is given at this point, vi now advances to the start of the + next line instead of ringing the bell. This is compatible with SVR4 vi and + seems to be what POSIX specifies. +* If the replacement part of a substitute command consists of a single '%', + as in ':s/foo/%/', the replacement part of the previous substitution is + used. This is compatible with SVR4 vi and is specified by POSIX. +* Fixed a number of possible heap overflows, e.g. because of too long tag + strings. + +Release 6/5/04 +* Some changes were made to the Makefile to support RPM builds. In particular, + the meaning of the DESTDIR and PREFIX variables was changed. +* An insufficient size of a variable caused the window size set to 8 on + FreeBSD if the terminal baud rate was 38400. + +Release 1/3/04 +* Changes to the included libterm only: Made multiple tc= capabilities in + a termcap entry work; recognize tc= also if it is not the last capability + in an entry (Bugreport by Andrew Minter). + +Release 9/3/03 +* The code did not check st_blksize from stat(2) at other points besides + the one fixed in the last release. +* The keyboard input character with code 255 ("y in ISO-8859-1) was + misinterpreted as end-of-file indicator. + +Release 8/27/03 +* Compile fixes for AIX and HP-UX (Mike Jetzer). +* Delete temporary file when preserving was successful after receiving + SIGHUP or SIGTERM (Fix taken from 4.3BSD Reno). +* Set MAILRC to /dev/null in expreserve to avoid reading the user's + mail initialization file. +* Optionally use Caldera's 'UNIX(R) Regular Expression Library' to + get POSIX.2 compatible REs. +* Don't refuse to quit with 'No write since last change' if a line of a + newly read input file is too long but no changes were made by the user. +* The POSIX_2 preprocessor define has been removed. The behavior previously + enabled by this variable is now the default (except as noted below). +* Backslash inside RE bracket expresssions (as in [\]]) is now recognized + as an escape character by default. This is not POSIX.2 compliant, but is + compatible with historic vi behavior, is demanded by the some traditional + standards such as the System V Interface definition, and is compatible + with vim. To get POSIX.2 compliant behavior here, define NO_BE_BACKSLASH. +* The input buffer did overflow with large values of st_blksize from stat(2). + +Release 4/3/02 +* Option "showmode" has no effect on hardcopy or glass terminals (P). +* Fixed undo for :r! command. +* Interrupt character is not misinterpreted as DEL on insertion (P). +* Fixed interaction of <count>~ vi command with abbreviations and macros (P). +* Avoid horizontal scrolling of showmode string on wraparound to last line (P). +* No showmode string is printed when executing a macro. +* Recovery listing fixed not to mix characters from long filenames in + /var/preserve with /var/tmp listing (P). +* Catch SIGXFSZ (file size limit exceeded). + +Release 3/3/02 +* Separated terse/noterse messages for RE errors (P). +* The expreserve and exrecover commands work again (P). +* Passing beyond EOL in <count>~ vi command is not an error (P). +* Fixed segmentation violation on mdjc'd and related bugs (Sven Mascheck). +* Marks remain on lines changed in an undo operation. +* Close mapmalloc file descriptor for /dev/zero on exec() (P). +* Added -L and -V command line options as in SVr4 ex. +* POSIX.2: Processing EXINIT does not depend on stdin being a terminal. +* POSIX.2: No newline is appended to an empty file in visual mode. +* Fixed segmentation violation on :f^V^M^M and similar commands. +* Mapmalloc extended to allocate and release multiple memory pools. +* Exrecover lists /var/tmp in addition to /var/preserve. +* Have multiple attempts to create named buffer temporary file. +* Size limit for temporary file names removed. + +Release 2/17/02 +* POSIX.2: Backslash has no special meaning inside RE bracket expressions. +* RE cleanup; make it compile without POSIX_2 defined (P). +* Fixed $(CC) to "$(CC)" for libterm compilation (Felix von Leitner) (P). +* Support for LC_MESSAGES using catgets() added. +* Renamed POSIX define to POSIX_1. +* Renamed UNIX98 define to POSIX_2. +* POSIX.2: Fixed a conflict between -t tag and wrapscan option. +* POSIX.2: Take the initial value for the vi scroll command from scroll var. +* <count>~ vi command fixed to work with repeat and control chars in text (P). +* Fixed recursion on :ab abbreviations (Bugreport by Matthias Kopfermann). +* Fixed undo for :<addr>r command in visual mode. +* Made modelines compatible to SVr4 ex: The option name is "modelines" or + "ml" now; a space or tab preceeding "ex:" or "vi:" is not required. +* Use O_EXCL and O_NOFOLLOW when creating temporary files, if possible. + +Release 1/26/02 +* Use mmap() for memory allocation if possible. +* POSIX.2: Added RE interval expressions \{m,n\} (taken from V7 expr). +* POSIX.2: Added backreferences \1 ... \9. +* Print one-character mode strings if both "showmode" and "terse" are set. +* Added the "flash" variable. +* POSIX.2: "~" visual command accepts a count. +* License notices added. + +Release 5/21/01 +* If compiled using BIT8, all characters except ASCII NUL can now be handled. +* Support larger files if LARGEF is defined. + +Release 09/23/00 +* POSIX locale support for 8bit character sets is enabled by -DBIT8. +* Regex code is 8bit clean. +* Smaller fixes for SVR4 systems. +* POSIX termios support including job control. +* POSIX sigaction support. +* Check for ELF executables and compressed files. +* Extended the pattern for temporary files from 5 to 10 digits. +* ANSI C stdarg function calling added, Linux/ia64 needs them. +* Reintegrated the UCVISUAL routines from 4.4BSD ex. +* Only use the "ic" termcap sequence if "im" is empty. +* POSIX.2: Command line options added and revised. +* POSIX.2: Added a "showmode" option for novices. +* POSIX.2: Ex respects the environment variables COLUMNS and LINES. +* POSIX.2: Added an "exrc" option like on POSIX.2 ex; arbitrary .exrc + files are ignored unless it is set in EXINIT or ~/.exrc. +* POSIX.2: If .exrc files are world or group writeable, they are ignored + unless "sourceany" is set. +* Ex now provides malloc routines. They are necessary since C library + calls like setlocale could otherwise break the sbrk calls in ex. As + an additional benefit, linking against ncurses is now possible. + +Release 31/05/00 +* String extraction using mkstr and xstr is not longer be done. +* An ANSI C preprocessor may be used. +* Changes of symbol names due to collisions on newer systems. +* Fixed a null pointer reference in ex_tty.c. +* Included the 2.11BSD termcap in a subdirectory. Ex could use any + termcap library, however, that does not use malloc(). +* Support of eight bit characters excluding the range 0200 to 0237 is + enabled with -DISO8859_1. It does not include the regular expression code, + but otherwise works well in practice with the ISO-8859-1 character set. + +Fixes for problems that were introduced in this port are marked (P), unless +they only affect newly introduced parts (such as multibyte support). |
