Re-jig the module-weight calculations.
- modules can have a weight
- module instances can have a weight
- jobs, from the module, can have a weight
This is now configurable on a case-by-case basis, rather than having
C++ only as an option and a weird hack for unpackfs.
This is more a test-inspired hack than anything else: since signals
are delivered asynchronously, we can end up delivering progress
signals out-of-order, and then the signal spy lists them wrong:
progress goes backwards.
Insert a tiny delay between jobs to allow signals to be delivered
in-order.
- compute weights and accumulations beforehand
- mutex-lock structures so you can enqueue while running jobs
- simplify progress reporting calculations
- doesn't actually run any jobs
In advance of PR #1491, test loading and stringlist extraction.
- from code, extraction works "normally"
- for YAML data, the stringlist isn't actually a stringlist
- The weight is the module (instance) weight, which can be
- the default weight of 1
- the weight specified for the module (in module.desc / the module
descriptor; this defaults to 1, above)
- the weight specified for the instance (in settings.conf)
The last of these "wins"; weights are constrained to 1..100
The weight isn't actually used in progress computation yet.
- loads emergency, noconfig, requiredModules keys
- warns (and marks descriptor invalid) if there are unused / unknown
keys left over in the descriptor data.
- add fields -- all const, all bogus -- to the descriptor,
introduce a stub method to load the descriptor from
YAML data (e.g. read from module.desc)
- lighten the type-naming in Module a little, with usings
- In most cases, you **know** the table covers all the enum
values, and the extra parameter *ok* is just annoying.
Provide a convenience that doesn't distinguish empty
from empty-but-valid.
- move the enums
- expose the named-enum functions for them
- **start** replacing Descriptor with something stronger; this fails
zero tests so it obviously wasn't tested at all
- setting the weight in *instances* should be different from letting
the default weight (of 1) stand; explicitly saying 1 should
carry some weight (ha!)
- any invalid instance key will cause a complaint
- "new" custom instances in sequence get a complaint, but
the instance description added to the list is valid
- there's no reason to ignore custom instances that are **not**
mentioned in the *instances* section: it may be useful to
name more that one even without distinct config files.
- no more weights in constructors; do that in fromSettings() only.
- simplify test to drop those constructors
- set config file also for "normal" descriptors; fix test
- expose, for testing purposes, the load-from-YAML-data part
alongside the public constructor that reads a YAML file
- add test for building the list of instances
- looks funny
- is hard to get clang-format to respect this; it's intended as an
access-modifier, but those are baked into the code rather than
being configurable.
- is probably rare enough that #ifdef is acceptable
- Requirement.cpp was there "just in case" the header grew
functions that need an implementation, but that seems
unlikely (the header is just a struct of POD).
- the scripts are BSD-2-clause,
- the generated files are CC0 (I'm not *100%* sure about the
derived file CountryData_p.cpp, which lists countries and
country codes -- it **is** extracted from CLDR data which
is not CC0)
