Version 0.22.0 released

Happy 2016! I thought you might enjoy a new WP-CLI release before I dive into the RESTful CLI project.

Use wp cli update to install v0.22.0, representing 137 resolved issues and pull requests. Here’s what’s new.

search-replace for love and profit

Last month, Pantheon generously sponsored 15 hours of my time to address some of the long-standing bugs in the backlog, and make a few substantial enhancements too.

Let’s start with the good stuff:

  • Performance boost! Instead of running a MYSQL LIKE statement every 1000 rows, WP-CLI now just runs it once [#2304]. On a post meta table of ~3.5 million rows where 75,610 rows were affected, this change improved execution time from 734.926s to 225.509s (3.3x faster).
  • Use the --export=<filename> argument to create a SQL file of your transformed data, instead of making updates to the database [#2254]. This is a helpful feature when you want to prepare a database for a new environment without having to import and then run search-replace.
  • Wildcards can be used in table names [#2233]. search-replace against just meta tables with wp search-replace <old-string> <new-string> '*meta*'. Note: the pattern needs to be quoted, as * is a special character in Bash.

I also landed a number of search-replace bug fixes and minor enhancements:

  • Recurses objects by default when replacing inside of serialized data [#2222]. Among other things, this ensures theme mods are transformed as expected. You can disable the behavior with --no-recurse-objects. But, if you do disable the behavior, I’d like to hear from you. I think this is an unnecessary option we could remove at a later date.
  • Properly escapes quotes used in search or replace strings [#2230].
  • Lets users know to flush their persistent object cache after a search-replace procedure is performed [#2236].
  • Bails early when the replacement string is the same as the search string [#2235].
  • Indicates execution time when running search/replace with --verbose [#2242].
  • Prevents unnecessary calls to $wpdb->update() when there are no replacements to be made [#2245].
  • Drops unnecessary REGEXP query when in regex mode [#2305].

Changes to supported versions

WP-CLI’s minimum supported WordPress version is now 3.7 [#2261].

We also officially support PHP 7 [#2330].

Everything else in v0.22.0

Improvements to wp scaffold (plugin|plugin-tests):

  • Makes Travis less noisy by only sending email notifications on the initial build failure for a branch [#2194].
  • Plugin header follows WordPress’ PHPDoc standards [#2197].
  • Adds .dist extension to PHPUnit config file to permit overriding with a local config file [#2247]
  • Parses readme.txt to find WordPress versions to use as Travis tested versions [#2255].
  • Includes a default .gitignore [#2297].

New flags for existing commands:

  • wp core update --minor to only perform minor updates [#2256].
  • wp (post|comment|user) meta delete <id> --all to delete all meta values on a given object [#2265].
  • wp core update-db --dry-run to see whether a database needs an upgrade [#2293].
  • wp media regenerate --only-missing for faster performance on sites with lots of images where only a small number are missing sizes [#2292].
  • wp cron event run --all to execute all registered cron events [#2323].
  • wp site empty --uploads to empty a site and delete its uploads directory too [#2339].
  • wp core install --skip-email to install without email notifications [#2345].
  • wp transient (get|set|delete) --network to manage site transients [#2351].

Framework enhancements:

  • Introduces wp_version_compare() when comparing WordPress versions [#2237]. SVN and Git tags include -src in $wp_version, which
    version_compare() doesn’t like.
  • Defers to the $PAGER environment variable when set [#2264].
  • Introduces a composer.lock file to the project, to fix dependencies to specific hashes [#2280].
  • Magically globalizes any new variables defined in wp-config.php, as they’re expected to be global [#2318].
  • If a --require=<file> is missing, specifies the context of where the missing file is referenced for easier debugging [#2336].
  • Use mustangostang/spyc instead of bundling our own copy [#2350]. The Spyc class is still available in the global namespace.
  • Introduces WP_CLIUtilsget_temp_dir() for safer temp directories [#2353].

Improvements to other commands:

  • Includes not_found label when scaffolding a custom taxonomy [#2196].
  • Permits installing remote plugin files without .zip in filename [#2193].
  • Warns when adding a user as a super admin when the user is already a super admin [#2202].
  • Uses WP_CLI::log() instead of WP_CLI::line() in wp import, so --quiet flag is respected [#2234].
  • Adds support to wp db tables for wildcard tables (e.g. *meta*), --all-tables-with-prefix, and --format=csv [#2250].
  • Improves error message when installing a plugin or theme and the resource isn’t found [#2253,#2267].
  • Supports custom wp export filename formats with --filename_format=<format> [#2230]
  • Assumes db errors during wp install to be installation failures, and reports accordingly [#2337].
  • Exposes plugin header details at runtime for wp scaffold plugin [#2338].
  • Includes ci/behat-tags.php in wp scaffold package-tests [#2342].

Bug fixes across the board:

  • Lets help run early when WP is detected, but not installed (e.g. wp core config --help) [#2190]. Bug was introduced in v0.20.0.
  • When scaffolding a child theme, creates a safe version of the parent theme slug for the child enqueue function [#2203]. Previously, if the parent slug included dashes, an invalid enqueue function would be scaffolded.
  • Suppresses error notices when looking for wp-config.php and PHP’s open_basedir is in effect [#2211].
  • Fixes error notice in WP_CLILoggersQuiet [#2210].
  • Fixes all_items label in custom post type scaffolding [#2213].
  • Ensures actually downloads the nightly WP-CLI Phar build, and not a redirect [#2214].
  • Sets the upload_space_check_disabled to 1 when installing multisite [#2238]. This mirrors core’s behavior on new installs.
  • Provides a more helpful message when image regeneration fails [#2239].
  • Properly updates menu sub-item parent when parent is deleted [#2262].
  • Stops prefixing rewrite rules with index.php when using wp rewrite structure [#2279].
  • Fixes typo in wp transient set synopsis [#2282].
  • Restores wp core verify-checksums for non-US English locales [#2287]. Bug was introduced in v0.21.0.
  • Switches to the readline library, when available, for better support of arrow keys using --prompt [#2325].
  • WP_CLIFormatter properly checks for null values on objects [#2322].
  • In wp media import, uses host instead of scheme to determine whether a file is remote or local, for Windows compatibility [#2324].
  • Ensures updating a plugin with an invalid --version=<version> specified doesn’t delete the plugin [#2346].
