From bcdeeca524b4fe6a9f2da195fb6022dbcaf057a1 Mon Sep 17 00:00:00 2001 From: Al-Amin Firdows Date: Sat, 27 Jun 2026 09:57:55 +0600 Subject: [PATCH 1/8] feat: Add granular cache flushing commands Adds granular cache flushing for posts, terms, comments, users, and options. Implements CLI equivalents for WordPress cache-clearing functions: - wp cache flush-post [ID] - wp cache flush-term [ID] - wp cache flush-comment [ID] - wp cache flush-user [ID] - wp cache flush-option [name] Addresses #108: Allow selective cache clearing instead of flushing entire cache. Without IDs/names, clears all cache groups for that type. With IDs/names, clears specific items using WordPress core functions. --- composer.json | 5 + features/cache-flush-granular.feature | 126 +++++++++++++++++++ src/Cache_Command.php | 175 ++++++++++++++++++++++++++ 3 files changed, 306 insertions(+) create mode 100644 features/cache-flush-granular.feature diff --git a/composer.json b/composer.json index aba06a05..e48a0f05 100644 --- a/composer.json +++ b/composer.json @@ -39,7 +39,12 @@ "cache decr", "cache delete", "cache flush", + "cache flush-comment", "cache flush-group", + "cache flush-option", + "cache flush-post", + "cache flush-term", + "cache flush-user", "cache get", "cache incr", "cache patch", diff --git a/features/cache-flush-granular.feature b/features/cache-flush-granular.feature new file mode 100644 index 00000000..9e08ee47 --- /dev/null +++ b/features/cache-flush-granular.feature @@ -0,0 +1,126 @@ +Feature: Granular cache flushing operations + + @skip-object-cache + Scenario: Flush post cache + Given a WP install + And a wp-content/mu-plugins/test-harness.php file: + """ + 123, 'post_title' => 'Test' ), 'posts' ); + wp_cache_set( 'meta_123', array( 'key' => 'value' ), 'post_meta' ); + }; + WP_CLI::add_hook( 'before_invoke:cache flush-post', $cache_post ); + """ + + When I run `wp cache flush-post` + Then STDOUT should contain: + """ + Success: Post caches cleared. + """ + + When I run `wp cache flush-post 123` + Then STDOUT should contain: + """ + Success: Post cache for ID 123 cleared. + """ + + @skip-object-cache + Scenario: Flush term cache + Given a WP install + And a wp-content/mu-plugins/test-harness.php file: + """ + 5 ), 'terms' ); + wp_cache_set( 'term_meta_5', array(), 'term_meta' ); + }; + WP_CLI::add_hook( 'before_invoke:cache flush-term', $cache_term ); + """ + + When I run `wp cache flush-term` + Then STDOUT should contain: + """ + Success: Term caches cleared. + """ + + When I run `wp cache flush-term 5` + Then STDOUT should contain: + """ + Success: Term cache for ID 5 cleared. + """ + + @skip-object-cache + Scenario: Flush comment cache + Given a WP install + And a wp-content/mu-plugins/test-harness.php file: + """ + 1 ), 'users' ); + wp_cache_set( 'user_meta_1', array(), 'user_meta' ); + }; + WP_CLI::add_hook( 'before_invoke:cache flush-user', $cache_user ); + """ + + When I run `wp cache flush-user` + Then STDOUT should contain: + """ + Success: User caches cleared. + """ + + When I run `wp cache flush-user 1` + Then STDOUT should contain: + """ + Success: User cache for ID 1 cleared. + """ + + @skip-object-cache + Scenario: Flush option cache + Given a WP install + And a wp-content/mu-plugins/test-harness.php file: + """ + 'value' ), 'options' ); + }; + WP_CLI::add_hook( 'before_invoke:cache flush-option', $cache_option ); + """ + + When I run `wp cache flush-option` + Then STDOUT should contain: + """ + Success: Option caches cleared. + """ + + When I run `wp cache flush-option my_option` + Then STDOUT should contain: + """ + Success: Option cache for 'my_option' cleared. + """ diff --git a/src/Cache_Command.php b/src/Cache_Command.php index ab5c8b56..df6e425e 100644 --- a/src/Cache_Command.php +++ b/src/Cache_Command.php @@ -611,4 +611,179 @@ function ( $key ) { } } } + + /** + * Clears post related caches. + * + * @subcommand flush-post + * + * ## OPTIONS + * + * [] + * : Post ID.
