2015-11-04ash: add support for bash 'function' keywordRon Yorston
Where the POSIX shell allows functions to be defined as: name () compound-command [ redirections ] bash adds the alternative syntax: function name [()] compound-command [ redirections ] Implement this in ash's bash compatibility mode. Most compound commands work (for/while/until/if/case/[[]]/{}); one exception is: function f (echo "no way!") The other two variants work: f() (echo "ok") function f() (echo "also ok") function old new delta parse_command 1555 1744 +189 tokname_array 232 240 +8 .rodata 155612 155566 -46 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/1 up/down: 197/-46) Total: 151 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2015-11-01i2cdump: display the numeric value for block read ioctl() errorsBartosz Golaszewski
This makes busybox i2cdump compatible with the upstream version, which also displays the numeric error value in case of a block read failure. Signed-off-by: Bartosz Golaszewski <bartekgola@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2015-11-01i2cdump: bail-out if block read failsBartosz Golaszewski
We should bail-out if i2c_smbus_read_block_data() or i2c_smbus_read_i2c_block_data() return 0 or less. Add the missing check for the former and fix the existing for the latter. Signed-off-by: Bartosz Golaszewski <bartekgola@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2015-11-01i2cdump: use I2C block mode for the 'i' mode parameterBartosz Golaszewski
Currently we're calling i2c_smbus_read_block_data() for both 'i' and 's' mode parameters. If the bus doesn't support SMBus block mode, then the i2c access ioctl() fails. Make i2cdump behave compatibly with upstream version by calling i2c_smbus_read_i2c_block_data() for I2C block.

2015-11-01i2cdump: don't read block data in non-block modesBartosz Golaszewski
We currently read data twice in byte mode. Add a check to avoid calling i2c_smbus_read_i2c_block_data() if we're not in I2C or SMBus block mode. Signed-off-by: Bartosz Golaszewski <bartekgola@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2015-11-01i2cdetect: fix address skipping in auto modeBartosz Golaszewski
If the bus doesn't support SMBus Quick Write or Receive Byte commands and we're running in auto mode all addresses will be skipped resulting in an empty table being printed. This is caused by not restoring the auto mode after it's been changed for certain address ranges - we need an additional variable to hold the temporary state.

2015-10-30ash: allow popredir to be called if the stack is emptyRon Yorston
If /tmp/test.sh is a script that tries to run a second script which happens to be non-executable this: command . /tmp/test.sh causes a seg fault. This is because clearredir is called in the error path to clear the stack of redirections. The normal path then calls popredir, but popredir fails when the stack is empty.

2015-10-30ash: fix EXEXEC status clobberingRon Yorston
evalcommand always clobbers the exit status in case of an EXEXEC which means that exec always fails with exit status 2 regardless of what it actually returns. This patch adds the missing check for EXEXEC so that the correct exit status is preserved. It causes the test ash-misc/exec.tests to succeed. Based on commit 7f68426 in dash git, by Herbert Xu.

2015-10-30ash: add tests for failures of the exec and command builtinsRon Yorston
The exec builtin should return an exit status of 127 if the command can't be found. It doesn't: it returns 2. If the command builtin is used to source a script that runs a second script that doesn't exist ash should issue an error. Instead it seg faults.

The virtual y can be larger - and we can be even writing there since we are taking into account the y offset. Avoids possible crash.
