* [BUILTIN] Add another missing LC_COLLATE to mkbuiltinsMatthew Burgess2009-08-31

* [BUILTIN] Fix NUL termination in readcmdHerbert Xu2009-08-31
| | | | | | | | | | | | Commit 55c46b7286f5d9f2d8291158203e2b61d2494420 ([BUILTIN] Honor tab as IFS whitespace when splitting fields in readcmd) introduced a bug where sometimes garbage would follow the last field preceding the end-of-line. This was caused by an off-by-one error in the string length calculation. This patch fixes the bug. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [EVAL] Revert SKIPEVAL into EXEXITHerbert Xu2009-08-11
| | | | | | | Now that eval handles EV_TESTED correctly, we can remove the SKIPEVAL hack and simply use EXEXIT for set -e. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [EVAL] Pass EV_TESTED into evalcmdHerbert Xu2009-08-11
| | | | | | | | | | | | | | | | | | This patch fixes the case where the eval command is used with set -e and as part of a construct that should not cause the shell to abort, e.g., as part of the condition of an if statement. This is achieved by propagating the EV_TESTED flag into the evalstring function through evalcmd. As this alters the prototype of evalcmd it is now invoked explicitly by evalbltin. The built-in infrastructure has been changed to accomodate this special case. In order to ensure that the EXIT trap is properly executed this patch clears evalskip in exitshell. This wasn't needed before because of the broken way evalstring worked where it always clears evalskip when called by minusc. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [SHELL] Add preliminary LINENO supportRocky Bernstein2009-08-11
| | | | | | | | | | | | | | | | | | | | | | | Looks like in contrast to what the dash.1 manual page says, expansion of PS{1,2,4} does work. Here is a little patch to set LINENO. The ways in that it is less than ideal mirror the ways that the line number error reporting is also less than ideal. For example if you run this: ( x=$((1/0)) # Just to add another line # And another ) # error reports this line The error reported will be the closing parenthesis even though I think most people would prefer the error to be the one where x was set.

* [BUILTIN] Honor tab as IFS whitespace when splitting fields in readcmdStefan Potyra2009-08-11
| | | | | | | | | | | | | | | | | | | When I try to split fields by tabs, dash doesn't honour multiple tabs between fields as whitespace (at least that's how I interpret [1], please correct me if I'm wrong). #!/bin/sh # "1\t2\t\t3" TESTSTRING="1 2 3" # only "\t" IFS=" " echo "$TESTSTRING" | while read p1 p2 p3; do echo "p1=${p1}, p2=${p2}, p3=${p3}" done Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [REDIR] Fix incorrect savefd conversionsHerbert Xu2009-06-27

* [JOBS] Fix dowait signal raceHerbert Xu2009-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This test program by Alexey Gladkov can cause dash to enter an infinite loop in waitcmd. #!/bin/dash trap "echo TRAP" USR1 stub() { echo ">>> STUB $1" >&2 sleep $1 echo "<<< STUB $1" >&2 kill -USR1 $$ } stub 3 & stub 2 & until { echo "###"; wait; } do echo "*** $?" done The problem is that if we get a signal after the wait3 system call has returned but before we get to INTON in dowait, then we can jump back up to the top and lose the exit status. So if we then wait for the job that has just exited, then it'll stay there forever. I made the original change that caused this bug to fix pretty much the same bug but in the opposite direction. That is, if we get a signal after we enter wait3 but before we hit the kernel then it too can cause the wait to go on forever (assuming the child doesn't exit). In fact this is pretty much exactly the scenario that you'll find in glibc's documentation on pause(). The solution is given there too, in the form of sigsuspend, which is the only way to do the check and wait atomically. So this patch fixes Alexey's race without reintroducing the old bug by converting the blocking wait3 to a sigsuspend. In order to do this we need to set a signal handler for SIGCHLD, so the code has been modified to always do that. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* [BUILD] Fixed build on OS XMark Mentovai2009-01-13
| | | | | | | | | | | | | | | | | | | | Hi, Herbert and friends. I've created a small patch that allows dash to be built on Mac OS X. I'm contributing it here with the hope that it's suitable for inclusion in dash. The changes in this patch are: - __attribute__((__alias__())) is not supported, add an autoconf check - open64 is not present although the stat64 family is, separate the autoconf checks - A syntax error had slipped into a non-glibc codepath - mkbuiltins had a nonportable mktemp invocation for the case where tempfile is not availalble Nothing in this patch is actually Mac OS X-specific, so it might aid portability to other platforms as well.

* [EXPAND] Fixed non-leading slash treatment in expmetaHerbert Xu2008-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | Back in January an attempt was made to fix the interpretation of quoted slashes in expmeta. However, this only fixed those cases where the quoted slash is at the front of the word. The case of non-leading slashes caused the previous directory part to gain a back slash suffix which causes subsequent pattern matches to fail. This patch fixes this by removing the back slash in that case. Thanks to Romain Tartière fox reporting this bug.

| | | | | | | | | | | | | | | | (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.

| | | | | | | | | | | | | | | | Previously expandstr used the string "" to indicate that it needs to be treated just like a here-doc except that there is no terminator. However, the string "" is in fact a valid here-doc terminator so now that we deal with it correctly expandstr no longer works in the presence of new-lines in the prompt. This patch introduces the FAKEEOFMARK macro which does not equal any real EOF marker but is distinct from the NULL pointer which is used to indicate non-here-doc contexts.

* [EXPAND] Expand here-documents in the current shell environmentHerbert Xu2007-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously we always expanded here-documents in a subshell. This is contrary to the POSIX specification and how other shells behave.

This patch move the expansion into the current shell environment. Test case: unset a cat <<- EOF > /dev/null ${a=NOT} EOF echo ${a}BAD Old result: BAD New result: NOTBAD
* [EXPAND] Removed herefd hackHerbert Xu2007-11-11
| | | | | | | | | | | The herefd hack goes back more than a decade. it limits the amount of memory we have to allocate when expanding here-documents by writing the result out from time to time. However, it's no longer safe because the stack is used to place intermediate results too and there we certainly don't want to write them out should we be short on memory. In any case, with today's computers we can afford to keep the entire result in memory and write them out at the end.
