Follow-up to #413 and #414, found by running db-command in Docker containers through wp-cli/.github#313.

SQLite options

The SQLite built for the images of PHP 8.0 and older (#413) only had a few of the compile options Debian uses. Among the missing ones is SQLITE_ENABLE_DBSTAT_VTAB, which wp db size needs, and without it the SQLite jobs of db-command on PHP 7.2 to 8.0 hung until they were cancelled. SQLite is now built with the same options as Debian's (compared through pragma compile_options, only HAVE_ISNAN differs, which is detected by the build).

MariaDB client on PHP 7.2

For users that do not exist, MySQL 8 offers a pseudo-random authentication method, including caching_sha2_password and sha256_password. The MariaDB 10.3 client of Debian 10 (the base of the PHP 7.2 image) cannot handle either (missing plugin, or "RSA Encryption not supported" with GnuTLS), so scenarios that expect Access denied for --dbuser=no_such_user failed depending on the name. That image now installs the MariaDB 10.6 client from MariaDB's archive. libmariadb3 is installed explicitly in every image, as it carries the authentication plugins.

Testing

db-command with this Dockerfile, 4 workers in Docker, all passed:

PHP	Database	WordPress	Time
7.2	MySQL 8.0	6.9	38 s
7.2	SQLite	6.9	21 s
7.4	SQLite	latest	18 s
8.0	SQLite	latest	140 s (includes building the image)

Before, PHP 7.4 SQLite hung in wp db size, and PHP 7.2 MySQL 8.0 failed 6 scenarios.

Summary by CodeRabbit

• Chores
  • Updated container build dependencies to include the MariaDB client library and configure the MariaDB package source on Debian Buster.
  • Expanded SQLite build capabilities while retaining the existing version check.

Walkthrough

The Dockerfile adds MariaDB 10.6.27 repository setup for Debian Buster, installs libmariadb3, and enables additional SQLite compile-time options.

Changes: Docker database support

The Docker image may reject UPDATE and DELETE statements using LIMIT; rebuild SQLite with the option enabled during parser generation.
