Hello everyone,
I finaly completed the refactoring of XML parsing at the controller
and finalized the patch set. I'll try to briefly summarize here what
has changed.
The goal of this series is to decouple parsing of the XMLs from processing
their contents. Up to now, the execution of lnst-ctl was controlled by the
parser, which proved to be very limiting and also quite convoluted.
This series introduces an intermediary data structure, a sort-of abstract
syntax tree, that is generated by the XML parser. The controller then
doesn't interact with the parser directly; it works with this new
structure instead.
Using this approach, I was able to move all the semantic checks to the
controller while keeping the structural checks in the parser. This will
allow us to use XML schemes for checking the structure in the future.
Apart from that, it makes the parser code much more readable (in my
opinion). Each node of the abstract syntax tree also contains references
back to the original XML file that are used for much more accurate
error reporting.
The series also contains a facelift of the former <command_sequence>
tag (now <task>), which is very closely related to the refactoring
process. The changes are the most prominent with commands. Each
command used to be represented by the <command> tag with a type
attribute. This was changed, so each command type now has it's own
tag instead.
For example:
<command type="test" value="IcmpPing" machine_id="tm">
...
</command>
changed to
<test module="IcmpPing" machine="tm">
...
</test>.
The commands are usualy shorter and easier to distinguish from each
another now.
To help with converting the existing recipes to the up-to-date format,
I modified the 'misc/recipe_conv.py' script, which can be used to
automatically conver all your recipes.
I tested everything I could with my current setup. Please let me know
if you run into problems :-).
Cheers,
-Radek
