| * ash: make "locak VAR" unset VAR (bash does that)Denys Vlasenko2014-03-161-0/+3

* | ash: further tidying up of MinGW forkshellRon Yorston2014-04-301-41/+47
| | | | | | | | | | | | | | The forkpoint_fn in the forkshell structure was redundant as the fpid element indicated which function to call in the child. Explicitly set fpid before calling spawn_forkshell and replace the forkpoint_fn array with a function, forkshell_child.

* | 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.

* | ash: add noconsole option to hide console window on WIN32Ron Yorston2013-05-241-0/+15
| | | | | | | | | | | | When a shell script is spawned from a GUI application a console window is displayed. If the noconsole option is set the console window is hidden.
* | ash: Add a very small timeout to nonblocking waitRon Yorston2013-05-031-1/+1
| | | | | | | | | | | | | | | | | | | | A nonblocking waitpid was implemented using WaitForMultipleObjects with a timeout of 0. This was to fix an issue where builtin commands in a foreground shell were blocked while a background command was running. However, this caused the shell to consume 100% CPU. A workaround seems to be to use a very small (1ms) timeout.
