| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes msh handle variable expansion within backticks more correctly. Current behaviour (wrong): -------------------------- BusyBox v1.00-rc3 (2004.08.26-11:51+0000) Built-in shell (msh) Enter 'help' for a list of built-in commands. $ A='`echo hello`' $ echo $A `echo hello` $ echo `echo $A` hello $ New behaviour (correct): ------------------------ BusyBox v1.00-rc3 (2004.08.26-11:51+0000) Built-in shell (msh) Enter 'help' for a list of built-in commands. $ A='`echo hello`' $ echo $A `echo hello` $ echo `echo $A` `echo hello` $ The current behaviour (wrong according to standards) was actually my fault. msh handles backticks by executing a subshell (which makes it work on MMU-less systems). Executing a subshell makes it hard to only expand variables once in the parent. Therefore I export all variables that will be expanded within the backticks and let the subshell handle the expansion instead. The bug was found while searching for security leaks in CGI-scripts. Current behaviour of msh makes it easy to expand backticks by mistake in $QUERY_STRING. I recommend appling the patch before release of bb 1.00. /Jonas git-svn-id: svn://busybox.net/trunk/busybox@9199 69ca8d6d-28ef-0310-b511-8ec308f3f277

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A question was posted a month ago by Mark Alamo to see if others had problems with sourcing subscripts within msh. We asked his firm to fix the msh.c bug he described because we didn't have enough time to do it ourselves. When msh.c is executing a compound statement and there is a . command to source another script file, msh.c will not execute the subscript until it's completed executing the rest of the compound statement. His example was this: Echo "Start" ; . ./subA; echo "mid" ; . ./subB ; echo "end" subA and subB execute AFTER end is printed in reverse order. The same is true if the sourced files are inside an if else fi, case esac, or any compound statement. Attached is a patch to msh.c. It fixes the problem. Cd to the root of your busybox tree and execute "patch -p1 < msh.c.patch" Unfortunately, I won't have more time to work on this so I hope that there aren't any problems!

| | | | | | | | | | | | | | | | | | | | | | | | | This is a bulk spelling fix patch against busybox-1.00-pre10. If anyone gets a corrupted copy (and cares), let me know and I will make alternate arrangements. Erik - please apply. Authors - please check that I didn't corrupt any meaning. Package importers - see if any of these changes should be passed to the upstream authors. I glossed over lots of sloppy capitalizations, missing apostrophes, mixed American/British spellings, and German-style compound words. What is "pretect redefined for test" in cmdedit.c? Good luck on the 1.00 release! - Larry git-svn-id: svn://busybox.net/trunk/busybox@8759 69ca8d6d-28ef-0310-b511-8ec308f3f277

handles all the basic stuff (for, case/esac, while, if/then/else), and is very small (adds just 38k on x86). It is not as rigorously correct about Bourne semantics as bash, but for most things it is quite workable. There is still some work to be done to further shrink it (it has its own globbing functions instead of using the libc ones, for example), but it is quite usable as is. -Erik git-svn-id: svn://busybox.net/trunk/busybox@2949 69ca8d6d-28ef-0310-b511-8ec308f3f277
