function acquia_search_multi_subs_get_expected_search_cores in Acquia Search Multiple Indexes 7

Same name and namespace in other branches

1. 8 acquia_search_multi_subs.common.inc \acquia_search_multi_subs_get_expected_search_cores()

Calculates eligible search core names based on environment information, in order of most likely (or preferred!) core names first.

The generated list of expected core names is done according to Acquia Search conventions, prioritized in this order: WXYZ-12345.[env].[acquia_db_name] WXYZ-12345.[env].[sitefolder] WXYZ-12345.[env].default WXYZ-12345_[sitename][env] WXYZ-12345.dev.[sitefolder] (only if $ah_site_environment isn't 'prod') WXYZ-12345_[sitename]dev (only if $ah_site_environment isn't 'prod') WXYZ-12345 (only if $ah_site_environment is 'prod')

NOTE that [sitefolder] is a stripped-down version of the sites/* folder, such that it is only alphanumeric and max. 16 chars in length. E.g. for sites/www.example.com, the expected corename for a dev environment could be WXYZ-12345.dev.wwwexamplecom

Parameters

string $acquia_identifier: Subscription ID. E.g. WXYZ-12345

string $ah_site_environment: String with the environment, from $_ENV[AH_SITE_ENVIRONMENT]. E.g. 'dev', 'test', 'prod'.

string $ah_site_name: From $_ENV[AH_SITE_NAME]

string $sites_foldername: Optional. The current site folder within [docroot]/sites/*.

string $ah_db_name: The Acquia Hosting current DB name.

Return value

array The eligible core_ids sorted by best match first.
