This version of dash was obtained from
git://git.kernel.org/pub/scm/utils/dash/dash.git
It corresponds up to changeset 46abc8c6d8a5e9a5712bdc1312c0b6960eec65a4
omitting ee5cbe9fd6bc02f31b4d955606288de36c3d4eab.
Several changes have been made for klibc:
* The build system is changed from autotools to kbuild, with a static config.h
* Use of strtod() is guarded by HAVE_STRTOD, which we don't define
* The built-in times command, which requires floating-point support, is
disabled
* The signal_names[] array is replaced by a signal_name() function using
klibc's own signal name array. decode_signal() is changed similarly.
* The read built-in implements the -t option like bash
* mktokens is modified to support out-of-tree builds
* mkbuiltins is modified to sort with LC_ALL=C
* Some header files have header guards added
* Changelog and some manual pages are omitted
* Automatic whitespace fixups
HOWTO sync branch:
1) Generate mailbox of patches and fix up their paths:
git format-patch --subject-prefix='' -N --stdout <changeset>.. \
| awk '(FNR == 1 || blank) && /^From / { header = 1; hash = $2 }
header && /^Subject:/ { sub("^Subject:", "Subject: [klibc] dash:") }
{ print; blank = /^$/ }
header && blank {
print "[ dash commit", hash, "]"; print
header = 0
}' \
| filterdiff --strip 2 --addoldprefix a/usr/dash/ --addnewprefix b/usr/dash/ \
--exclude="*/configure.ac" --exclude="*/ChangeLog" \
--exclude="*/dash.1" --exclude="*/Makefile.am" \
--exclude="*/mksignames.c" \
> dash.mbox
2) Import patches from mailbox:
git am --whitespace=fix -k -i -s ../dash/dash.mbox
3) update config.h
Generate klibc config.h in dash repository:
automake --add-missing
autoreconf
./configure CC=klcc
