* [JOBS] Fix cmdtxt crash on if statementsLarry Doolittle2008-05-02
| | | | | | | | | | | | | | | | (Herbert: for context, see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=467065 ) This is a real bug in upstream dash, which has existed since at least dash-0.5.1 (July 2004). It is a latent bug in cmdtxt() (which I think applies only to pipes) as it handles "if" commands. The attached patch fixes it for me. It's possible this patch will fix one or more of #462414, #462977, and #463649. I'll send messages there to see if the submitters can test. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [EXPAND] Move parse-time quote flag detection to run-timeHerbert Xu2007-09-25
| | | | | | | | | | | | | | | | | | | | Because the parser does not recursively parse parameter expansion with respect to quotes, we can't accurately determine quote status at parse time. This patch works around this by moving the quote detection to run-time where we do interpret it recursively. Test case: foo=\\ echo "<${foo#[\\]}>" Old result: <\> New result: <>
* [REDIR] Replace copyfd by savefd and use dup2 elsewhereHerbert Xu2007-05-12
| | | | | | | There are two kinds of users to copyfd, those that want to copy an fd to an exact value and those that want to move an fd to a value >= 10. The former can simply use dup2 directly while the latter share a lot of common code that now constitutes savefd.
* [PARSER] Only use signed char for syntax arraysHerbert Xu2006-04-23
| | | | | | | | | The existing scheme of using the native char for syntax array indicies makes cross-compiling difficult. Therefore it makes sense to choose one specific sign for everyone. Since signed chars are native to most platforms and i386, it makes more sense to use that if we are to choose one type for everyone.
* [JOBS] Fixed support for disabling job controlHerbert Xu2005-10-30
| | | | | Since nobody has compiled with JOBS turned off for quite a while, it has bit-rotted. This patch makes it build again.
* [SIGNAL] Added default implementation of strsignalHerbert Xu2005-10-29
| | | | klibc doesn't have strsignal but it does have sys_siglist.
* Copyright/licence updates and remove all traces of sys/cdefs.hHerbert Xu2005-10-29
| | | | | | | | | | | This change updates the BSD licence to the three-clause version since NetBSD has already done so. This makes dash GPL-compatible. It also adds Christos Zoulas (NetBSD ash maintainer) to the COPYING file. I've added "copyright by Herbert Xu" to most files. Finally all CVS IDs and inclusion of sys/cdefs.h have been removed. The latter is needed for support of klibc.
