Kenno Vanommeslaeghe commented on AIRAVATA-779:
-----------------------------------------------
I don't fully understand the options you are proposing - could you provide some
examples?
Either way, I don't think there exists a generic solution. There are a lot of
UNIX tools and programs that accept a variable-length argument list. No matter
whether you go with a quoted or a comma-separated list, it will break services
that directly call such applications (without a wrapper script) because both
list types will be passed as a single argument. So either you have to break the
possibility of calling these UNIX tools and programs without a wrapper script,
or you have to specify that no Xbaya service should ever receive more than one
array (of a different type).
The big advantage of my proposal is that space-separated lists are the native
list format in UNIX, making the required wrapper script extremely simple:
{code:language=bash}
#!/bin/sh
# Wrapper script to pass 2 arrays to the program "ls"
arglist1="$1"
arglist2="$2"
# In this example, all the elements are passed individually to ls because we
don't quote "$arglist"
ls $arglist1 $arglist2
{code}
Or, an even simpler solution:
{code:language=bash}
#!/bin/sh
# The quotes are lost (unless we explicitly repeat them)
ls $1 $2
{code}
To further illustrate the ease of handling space-separated lists in the shell,
here's a script to perform an operation on each element of an array:
{code:language=bash}
#!/bin/sh
arglist1="$1"
for i in $arglist1 ; do
cp -p $i $i.bak
done
{code}
> Xbaya: handling of StringArray is not consistent with URIArray
