2019-03-30vi: allow manual screen update if SIGWINCH isn't supportedRon Yorston
On platforms that don't support SIGWINCH vi can be configured with FEATURE_VI_USE_SIGNALS disabled and FEATURE_VI_WIN_RESIZE enabled. This allows the user to force an update with ^L when the screen is resized. However, because the SIGWINCH handler hasn't run the virtual screen buffer won't have been updated and the display becomes corrupted. Fix this by calling new_screen() if necessary.

2019-03-26man: don't skip default path which appears in config fileRon Yorston
If the MANPATH environment variable isn't set a provisional default path of /usr/man is placed in man_path_list. This is only used if a configuration file doesn't contain an alternative path. If a configuration file lists the default path first: MANPATH /usr/man:/usr/share/man add_MANPATH() sees that the default entry is already present and skips it. As a result man_path_list only contains the second and subsequent components of the configured MANPATH. In such cases the path should not be skipped. function old new delta add_MANPATH 170 183 +13 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 13/0) Total: 13 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2019-02-27udhcpc: don't exit after backgrounding on -n -bAndrey Mazo
Currently, running "udhcpc -n -b" causes udhcpc to go to background and then exit after some time unless a lease is obtained. It's not very useful to do so as the calling process doesn't know if the lease was obtained or not anyway. The code actually tries to favor "-b" over "-n", but doesn't clear "-n" flag while clearing "-b" after backgrounding. So, clear "-n" flag after going into background. This effectively makes "-b" override "-n" completely and "-n -b" behave the same as "-b". This allows to override default "-n" option, passed to udhcpc by ifupdown, without recompiling busybox.

2019-02-25ash: eval: avoid leaking memory associated with redirections. Closes 7748Ron Yorston
The following constructs result in ever-increasing memory usage: while true; do { true; } </dev/null; done while true; do ( true; ) </dev/null; done For comparison, bash displays static memory usage in both cases. This has been fixed in dash by commit 2bc6caa. The maintainer writes: I have simplified evaltree so that it simply sets the stack mark unconditionally. This allows us to remove the stack marks in the functions called by evaltree.

2019-02-11vi: further fixes to undo after autoindentRon Yorston
Commit bb983f30e (vi: fix faulty undo after autoinsert) has a number of problems: - The commit message refers to 'autoinsert' when it really means 'autoindent'. - The indentation of undo_push_insert() was incorrect. - Most seriously the commit only fixed the problem for cases where the indentation was exactly one character. This is because undo_push() only allows single characters to be queued for UNDO_INS_QUEUED. Lifting this restriction allows the example given in the previous commit message (with a three character indent) to work. function old new delta undo_push 406 435 +29 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 29/0) Total: 29 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
