| * Introduce binfmt supportJean-Christophe PLAGNIOL-VILLARD2012-04-181-12/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | This will allow to execute any file and detect it's type to handle it. This will allow to use shell for bootp bootfile or dfu. You can register multiple hook for the same filetype. They will be execute in the invert order of register. If a hook does not handle the file you just return -ERESTARTNOHAND; This is only available with hush parser. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
* | hush: bail out of scripts on syntax errorSascha Hauer2012-05-021-1/+3
|/ | | | | | | | | | | | | | On a systax error we have to bail out of the shell instead of setting inp->p to NULL and crash barebox with a NULL pointer deref. This only happened in scripts. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> This fixes the problem I had (i.e. a boot loop caused by a stray fi in /env/bin/init).

* hush source: expand $PATHSascha Hauer2012-03-181-1/+16
| | | | | | | | The behaviour of other shells suggest that with source or '.' the path should be resolved using the PATH environment variable. Do the same in barebox. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* commands: remove struct command pointer from commandsSascha Hauer2012-02-271-4/+4
| | | | | | This is unused in all commands and thus can be removed. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* getopt: save and restore contextSascha Hauer2012-02-271-5/+10
| | | | | | | | | | | | execute_command is the single point where commands are executed and thus a new getopt context is needed. currently we call getopt_reset here to reset the context. This breaks though when a command tries to run a command itself by calling execute_command or run_command. In this case we have to store the context and restore it afterwards. The same is necessary in builtin_getopt. Currently noone does this so this one shouldn't fix a bug, but merely allows us to do such things later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* hush: implement getopt builtinSascha Hauer2010-10-081-2/+108
| | | | | | | | | | | | | | | | | | | | Positional parameters are not nice, so implement a getopt function. This has to be done as a builtin because otherwise we have no access to the parents argc/argv. getopt works as expected, here is a little example: while getopt "hs:" OPT do if [ $OPT = h ]; then echo "usage" exit 1 else echo "scr: opt: $OPT optarg: $OPTARG" fi done Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* hush: fix nasty memory leak in hushSascha Hauer2010-10-081-0/+1
| | | | | | | | | Fix memory leak in globbing part of hush. a simple '[' on the command line was enough to trigger it. We must call globfree() before setting the glob structure to zero. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* hush: Fix return code when calling 'exit' inside loopsSascha Hauer2010-03-301-11/+3
| | | | | | | | | | | | | | | | | | | | v2: Do not exit from all scripts but only the current one This fixes the case: barebox:/ cat /test if [ 0 = 0 ]; then exit 1 fi barebox:/ /test barebox:/ echo $? 0 barebox:/ Also, remove code to not allow exit from main shell. The for(;;) loop in common/startup.c will bring us back anyway. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | This has been done with the following script: find -path ./.git -prune -o -type f -print0 | xargs -0 -r sed -i \ -e 's/u2boot/barebox/g' \ -e 's/U2Boot/barebox/g' \ -e 's/U-boot V2/barebox/g' \ -e 's/u-boot v2/barebox/g' \ -e 's/U-Boot V2/barebox/g' \ -e 's/U-Boot-v2/barebox/g' \ -e 's/U_BOOT/BAREBOX/g' \ -e 's/UBOOT/BAREBOX/g' \ -e 's/uboot/barebox/g' \ -e 's/u-boot/barebox/g' \ -e 's/u_boot/barebox/g' \ -e 's/U-Boot/barebox/g' \ -e 's/U-boot/barebox/g' \ -e 's/U-BOOT/barebox/g' find -path ./.git -prune -o \( -name "*u-boot*" -o -name "*uboot*" -o -name "*u_boot*" \) -print0 | \ xargs -0 -r rename 's/u[-_]?boot/barebox/' It needs some manual fixup following in the next patch Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* hush: Fix quotingSascha Hauer2008-11-101-1/+1
| | | | | | | | | | | | | | | This patch removes adding of an additional \ when doing echo "\"" which gives \" instead of just " I checked in latest busybox hush and this code is still present there, but it behaves correctly in busybox due to some other code pathes I didn't investigate.
