| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A tilde expansion generates a valid pathname. Splitting it using IFS either leaves it unchanged or changes it to something unintended. Example: IFS=m HOME=/tmp; printf "%s\n" ~ Based on this commit authored by Jilles Tjoelker: http://git.kernel.org/cgit/utils/dash/dash.git/commit/?id=834629283f6c629a4da05ef60bae9445c954a19a Signed-off-by: Ron Yorston <rmy@tigress.co.uk> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* | ash: reset pointers to builtin environment variables after forkRon Yorston2014-01-141-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The builtin environment variables can be accessed using macros that reference the varinit array. initvar puts pointers to varinit into the variable hash table. During forkshell_prepare two copies of the builtin variables are made: once as the varinit array and again through the pointers in the hash table. One of these copies is accessed by code that uses the macros and the other by code that looks up the variable by name. This is the cause of the strange behaviour of IFS in backticks: https://github.com/pclouds/busybox-w32/issues/12 To avoid the problem the pointers in the hash table are reset to the varinit array in forkshell_init. It seemed easier to do it this way than to try and prevent the duplicate copies being made in the first place.

* | ash: don't copy localvars list during forkshellRon Yorston2014-01-131-23/+2
| | | | | | | | | | | | The localvars linked list is only required to tidy up local variables when a shell function returns. There's no point in copying it to a child process.
* | ash: prevent null-pointer exception with local variablesRon Yorston2014-01-101-1/+1
| | | | | | | | | | | | A local variable can have a null text pointer: if so, don't call strlen. localvar_copy handles this correctly because nodeckstrdup doesn't try to copy from the null pointer.
