We can free them after they are no longer needed. (Currently, being a NOEXEC applet is much larger waste of memory for the case of long-running awk script). function old new delta awk_main 831 827 -4 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-06-27vi: stored search pattern applies to ':s'Ron Yorston
The same stored search pattern applies to both search ('/') and search/replace (':s') operations. A search/replace operation with an empty "find" string (':s//abc/') should use the last stored search pattern, if available, and issue an error message if there is none. If the "find" string is not empty it should replace the stored search pattern. function old new delta colon 3952 4024 +72 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 72/0) Total: 72 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

follow links Add O_NOFOLLOW (and O_NOCTTY for good measure) to open calls like e2fsprogs does. In lsattr, when recursing, operate only on regular files, symlinks, and directories. (Otherwise, "lsattr /dev" can e.g. open a watchdog device... not good). At this time, looks like chattr/lsattr can't operate on symlink inodes - ioctls do not work on open(O_PATH | O_NOFOLLOW) fds. function old new delta lsattr_dir_proc 168 203 +35 change_attributes 410 408 -2 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 35/-2) Total: 33 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-06-21vi: fix backward search with GNU regexRon Yorston
With FEATURE_VI_REGEX_SEARCH enabled backward searches don't work. This is problematic on distros that enable regexes, such as Tiny Core Linux and Fedora. When calling GNU re_search() with a negative range parameter (indicating a backward search) the start offset must be set to the end of the area being searched. The return value of re_search() is the offset of the matched pattern from the start of the area being searched. For a successful search (positive return value) char_search() can return the pointer to the start of the area plus the offset. FEATURE_VI_REGEX_SEARCH isn't enabled by default but when it is: function old new delta char_search 256 247 -9 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-9) Total: -9 bytes Signed-off-by: Andrey Dobrovolsky <andrey.dobrovolsky.odessa@gmail.com> Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
