env: throw an error when an empty key is used

2013-05-09T21:03:05+00:00

If the environment contains an entry like "=value" "\0" we should throw
an error when parsing the environment. Otherwise, U-Boot will enter in
an infinite loop.

"env grep" - add support for regular expression matches

2013-05-01T20:24:00+00:00

When CONFIG_REGEX is enabled, the new option "-e" becomes available
which causes regular expression matches to be used.  This allows for
example things like these:

- print all MAC addresses:

	=> env grep -e eth.*addr
	eth1addr=00:10:ec:80:c5:15
	ethaddr=00:10:ec:00:c5:15

- print all variables that have at least 2 colons in their value:

	=> env grep -v -e :.*:
	addip=setenv bootargs ${bootargs} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off
	panic=1
	eth1addr=00:10:ec:80:c5:15
	ethaddr=00:10:ec:00:c5:15
	ver=U-Boot 2013.04-rc1-00289-g497746b-dirty (Mar 22 2013 - 12:50:25)

etc.

"env grep" - reimplement command using hexport_r()

2013-05-01T20:24:00+00:00

Also drop hstrstr_r() which is not needed any more.
The new code is way more flexible.

hashtable: preparations to use hexport_r() for "env grep"

2013-05-01T20:24:00+00:00

The output of "env grep" is unsorted, and printing is done by a
private implementation to parse the hash table.  We have all the
needed code in place in hexport_r() alsready, so let's use this
instead.  Here we prepare the code for this, without any functional
changes yet.

env: Add environment variable flags

2012-12-13T18:46:56+00:00

Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.

If the entry is not found in the env ".flags", then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

env: Add support for callbacks to environment vars

env: Hide '.' variables in env print by default

2012-12-13T18:46:55+00:00

When printing all variables with env print, don't print variables that
begin with '.'.  If env print is called with a '-a' switch, then
include variables that begin with '.' (just like the ls command).

Variables printed explicitly will be printed even without the -a.

env: Refactor apply into change_ok

2012-12-13T18:46:55+00:00

Move the read of the old value to inside the check function.  In some
cases it can be avoided all together and at the least the code is only
called from one place.

Also name the function and the callback to more clearly describe what
it does.

Pass the ENTRY instead of just the name for direct access to the whole
data structure.

Pass an enum to the callback that specifies the operation being approved.
