This patch fixes it by pushing the syntax stack if innerdq is

parser: Add syntax stack for recursive parsing
Without a stack of syntaxes we cannot correctly these two cases
together:
"${a#'$$'}"
"${a#"${b-'$$'}"}"
A recursive parser also helps in some other corner cases such
as nested arithmetic expansion with paratheses.
This patch adds a syntax stack allocated from the stack using
alloca. As a side-effect this allows us to remove the naked
backslashes for patterns within double-quotes, which means that
EXP_QPAT also has to go.
This patch also fixes removes any backslashes that precede right
braces when they are present within a parameter expansion context,
and backslashes that precede double quotes within inner double
quotes inside a parameter expansion in a here-document context.
The idea of a recursive parser is based on a patch by Harald van
Dijk.

parser: Fix backquote support in here-document EOF mark
Currently using backquotes in a here-document EOF mark is broken
because dash tries to do command substitution on it. This patch
fixes it by checking whether we're looking for an EOF mark during

This turned out to be easy to fix. The routine producing the "$-"
expansion failed to skip options for which there is no option letter,
but only a long-form name. In dash, 'nolog' and 'debug' are currently
the only two such options. Patch below.

commit

"udhcp: use poll() instead of select()"
Feb 16 2017
udhcp_sp_read() is meant to check whether signal pipe indeed has some data to read.
In the above commit, it was changed as follows:
- if (!FD_ISSET(signal_pipe.rd, rfds))
+ if (!pfds[0].revents)
return 0;
The problem is, the check was working for select() purely by accident.
Caught signal interrupts select()/poll() syscalls, they return with EINTR
(regardless of SA_RESTART flag in sigaction). _Then_ signal handler is invoked.
IOW: they can't see any changes to fd state caused by signal haldler
(in our case, signal handler makes signal pipe ready to be read).
For select(), it means that rfds[] bit array is unmodified, bit of signal
pipe's read fd is still set, and the above check "works": it thinks select()
says there is data to read.
This accident does not work for poll(): .revents stays clear, and we do not
try reading signal pipe as we should. In udhcpd, we fall through and block
in socket read. Further SIGTERM signals simply cause socket read to be
interrupted and then restarted (since SIGTERM handler has SA_RESTART=1).
Fixing this as follows: remove the check altogether. Set signal pipe read fd
to nonblocking mode. Always read it in udhcp_sp_read().
If read fails, assume it's EAGAIN and return 0 ("no signal seen").
udhcpd avoids reading signal pipe on every recvd packet by looping if EINTR
(using safe_poll()) - thus ensuring we have correct .revents for all fds -
and calling udhcp_sp_read() only if pfds[0].revents!=0.
udhcpc performs much fewer reads (typically it sleeps >99.999% of the time),
there is no need to optimize it: can call udhcp_sp_read() after each poll
unconditionally.
To robustify socket reads, unconditionally set pfds[1].revents=0
in udhcp_sp_fd_set() (which is before poll), and check it before reading
network socket in udhcpd.
TODO:
This might still fail: if pfds[1].revents=POLLIN, socket read may still block.
There are rare cases when select/poll indicates that data can be read,
but then actual read still blocks (one such case is UDP packets with
wrong checksum). General advise is, if you use a poll/select loop,
keep all your fds nonblocking.
Maybe we should also do that to our network sockets?

wget: fix fetching of https URLs with http proxy
When fetching a https:// URL with HTTP proxy configured
(e.g. with environment variable http_proxy=http://your-proxy:3128)
busybox was making a https connection to the proxy.
This was because the protocol scheme for the target URL was used to determine whether to connect to the proxy over SSL or not.
When the proxy is in use, the decision on whether to connect to the proxy over https
should based on the proxy URL not on the target URL.
