Hi,

This series makes the 'if' conditions less liberal, by formalizing a simple
expression tree based on bare boolean logic of configure option identifiers.

(this allows to express conditions in Rust in my QAPI-Rust PoC series)

thanks

v7: after Markus review
 - use is_present() in introspect too
 - drop now needless "qapi: _make_enum_members() to work with pre-built QAPISchemaIfCond"
 - add tests to cover more error cases
 - indentation updates
 - commit message updates
 - rebased

v6: after Markus review
 - drop the predicate tree, QAPISchemaIfCond simply holds the original object
 - introduce the dict operations ('all', 'any', 'not') in multiple patches
 - split QAPISchemaIfCond introduction in multiple patches
 - replace __bool__ usage with is_present()
 - removed __eq__
 - move cgen/docgen implementation to common.py
 - doc & commit message updates
 - rebased

v5:
 - drop the [ COND, ... ] sugar form
 - move documentation update as first patch
 - documentation and commit message tweaks

v4:
 - keep gen_if/gen_endif in common.py, reducing C codegen in schema.py
 - raise NotImplemented instead of False for unhandled __eq__
 - change check_if() to keep the json/raw form, add _make_if() to build a
   QAPISchemaIfCond
 - improve __repr__ usage
 - drop ABC usage
 - tweaks here and there
 - add various commit tags

v3:
 - rebasing on queued pt4 (after waiting for it to land)
 - improve documentation generation, to be more human-friendly
 - drop typing annotations from schema.py (not yet queued)
 - commit message tweaks

v2:
 - fix the normalization step to handle recursive expr
 - replace IfCond by QAPISchemaIf (JohnS)
 - commit message and documentation tweaks
 - mypy/flake8/isort

Marc-André Lureau (10):
  docs: update the documentation upfront about schema configuration
  qapi: wrap Sequence[str] in an object

  qapi: replace if condition list with dict {'all': [...]}
  qapi: add 'any' condition
  qapi: Use 'if': { 'any': ... } where appropriate

Except for the special casing assert in _make_implicit_object_type(),
which needs to handle schema objects, it's a mechanical change.

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Instead of building prepocessor conditions from a list of string, use
the result generated from QAPISchemaIfCond.cgen() and hide the
implementation details.

Note: this patch introduces a minor regression, generating a redundant
pair of parenthesis. This is fixed in a later patch in this
series ("qapi: replace if condition list with dict [..]")

  To: qemu-devel; +Cc: Marc-André Lureau, jsnow, Markus Armbruster

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Instead of building the condition documentation from a list of string,
use the result generated from QAPISchemaIfCond.docgen().

This changes the generated documentation from:
- COND1, COND2... (where COND1, COND2 are Literal nodes, and ',' is Text)
to:
- COND1 and COND2 (the whole string as a Literal node)

This will allow us to generate more complex conditions in the following
patches, such as "(COND1 and COND2) or COND3".

Adding back the differentiated formatting is left to the wish list.

  To: qemu-devel; +Cc: Marc-André Lureau, jsnow, Markus Armbruster

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Change the 'if' condition strings to be C-agnostic. It will accept
'[A-Z][A-Z0-9_]*' identifiers. This allows to express configuration
conditions in other languages (Rust or Python for ex) or other more
suitable forms.

Fixed in most, but not all instances, actually.  I can see some 50
remaining in generated qapi-*.[ch] at the end of this series.  Let's
s/fixed/mostly fixed/, and move on.

Possible improvement: have methods gen_if() and gen_endif(), so we can
replace

    gen_if(IFCOND.cgen())

and

    gen_endif(IFCOND.cgen())

by

    IFCOND.gen_if()

and

    IFCOND.gen_endif()

Can be done on top.

What about a TODO comment?   you suggest a suitable spot?

I don't think this matters much, it will never be a user-friendly text. But
we can leave a comment in the docgen() function to say that the sphinx
build could benefit from a formatted string.

Looks like you forgot to un-swap cgen_ifcond() and docgen_ifcond().  Can
do in my tree.

I suggested a more legible version in review of v6.  Not worth a respin
by itself.

Note to self: try to get rid of redundant parenthesis here.

Note to self: cgen_ifcond() and docgen_ifcond() are almost identical.
Refactor?

John hasn't answered my question whether :forms: makes sensw without

Mind if I squash in the move of the helper function to the beginning?

This is slightly subtle.

QAPISchemaIfCond.ifcond can look like one of

* {'all': [COND, ...]}

* {'any': [COND, ...]}          (only after PATCH 07)

* {'not': COND}                 (only after PATCH 08)

* STRING

* {}

This is just like the AST, except "absent" is now {} instead of None.
It can occur only at the root.

cgen_ifcond() and docgen_ifcond() are recursive, which means they
happily accept {} anywhere, and generate crap.

I believe the code works anyway, because it only ever creates {} in
QAPISchemaIfCond.__init__(), i.e. at the root.

Non-local correctness argument.  I'd like to try my hand at tweaking the
code so it's more obviously correct.  Not now.

s/a dict/an object/, since we're talking about JSON, not Python.

The existing error messages don't get this right 100% either.

s/a list/an array/

Can do both in my tree.

Syntax changes, but the error message remains "'if' condition [] of
struct is useless".  The new error message visible in bad-if-all.err
above refers to the same thing as "'all' condition of struct", which is
better.

Not worth a respin by itself.  If improving it is trivial, I'll do it in
my tree.

This will change (for the better) when we drop OrderedDict in favor of
plain dict.  Tolerable.

We have a bunch of check_FOO().  Some normalize, and have :forms:.  Some
don't, and don't have :forms:.  This patch changes check_if() not to
normalize.  So far, it leaves a degenerate :forms: behind.  Let's drop
it.  Can do in my tree.

Function docgen_ifcond(), I presume.  Method docgen() is a simple
wrapper.

Something like

    # TODO Doc generated for conditions needs polish

Only a few trivial things left to correct or improve.  I'll take care of

Pre-existing, but the (double (nesting)) is a bit lisp-y considering
this comment is user-facing, where using [] for one of the layers
might help readability.

I'm squashing it into PATCH 06, which already has similar changes to

Easier to read:

     'if': { 'all': ['defined(TEST_IF_ALT)',
