The http.addons_manifest is a map {module: manifest_dict} that is
populated upon the first http request. This map is basically a module
manifest cache with an extra `addons_path` key, the path of the module
on the file-system. This cache is eagerly populated upon the first http
request, the map is empty in non-http contextes (e.g. cron) which have
been a source of bugs (e.g. 50c8eb1).
A manifest cache is necessary because reading and parsing python files
from the file-system is not that cheap but there is no reason that cache
is located in `odoo.http`. A thin cache layer now wraps
`load_information_from_description_file()`/`load_manifest()` and is
lazily populated.
The `http.addons_manifest` have been removed. The extra `addons_path`
key is now present in the "normal" manifest. The `read_manifest()` was
hardly used so it has been deprecated. The only way to retrieve a
manifest is now `load_information_from_description_file()` which was
renamed `load_manifest()` (no cache) and `get_manifest()` (cache).
Side note about performances, the cache is necessary. Addons manifest
are read-only and reading + parsing python files from the file system is
not a cheap operation. Running the e-commerce tour
`@website_sale.test_04_admin_website_sale_tour` without cache on
`load_manifest()` requires 68,29 secs to complete on my laptop,
exceeding the default 1-minute time frame allowed in tests. Using a
cache the time is down to 36,53 secs. The performance impact is huge.
