These were previously written in very convoluted C which had to deal
with parsing the crazy output of the "lvm" command. In fact the
parsing was so complex that it was generated by the generator. It's
easier to do this in OCaml.
These are basically legacy APIs. They cannot be expanded and LVM
already supports many more fields. We should replace these with APIs
for getting single named fields from LVM.
Run this command across the source:
perl -pi.bak -e 's/(20[012][0-9])-20[12][012]/$1-2023/g' `git ls-files`
and remove changes to po{,-docs}/*.po{,t} (these will be regenerated
later when we run 'make dist').
Add a way to generate OCaml interfaces for all the modules in the
daemon that implement APIs: this makes sure that for them the
interface of each function matches the actual API specified in the
generator.
This change allows parts of the daemon to be written in the OCaml
programming language. I am using the ‘Main Program in C’ method along
with ‘-output-obj’ to create an object file from the OCaml code /
runtime, as described here:
https://caml.inria.fr/pub/docs/manual-ocaml/intfc.html
Furthermore, change the generator to allow individual APIs to be
implemented in OCaml. This is picked by setting:
impl = OCaml <ocaml_function>;
The generator creates ‘do_function’ (the same one you would have to
write by hand in C), with the function calling the named
‘ocaml_function’ and dealing with marshalling/unmarshalling the OCaml
parameters.
Run the following command over the source:
perl -pi.bak -e 's/(20[01][0-9])-2016/$1-2017/g' `git ls-files`
(Thanks Rich for the perl snippet, as used in past years.)
