core_auto_updates_settings()

Compatibility

Present in every tracked release (6.7.7 to 7.1.0), and compiles on PHP 7.4 through 8.6-dev.

Performance profile

How much work a call to core_auto_updates_settings() does, and what it touches: the algorithmic scaling, the Zend instruction count per call across PHP versions, the hooks it hands control to, and the core code that calls it. Measured from the compiled opcodes, not a stopwatch, so every number is identical on any machine running the same PHP version, and every function in core is ranked by cost.

Cost class

Moderate

Reads stored settings via get_site_option(), cached per request but not free on a cold cache.

Scaling

Constant

No loop in the body: the same number of instructions runs whatever you pass in.

Instructions

77–157

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 204.

Plugin surface

4 hooks

Third-party callbacks on 'allow_dev_auto_core_updates', 'allow_minor_auto_core_updates', 'allow_major_auto_core_updates' run inside this call, and their cost is not bounded by anything here.

Called by

0

Nothing in core calls this; the cost is only what you spend yourself.

What it touches

• optionnetwork optionget_site_option()called directly
• hookthird-party callbacksapply_filters()called directly
• transienttransientget_site_transient()one call below core_auto_updates_settings()

Further down the call graph this can also reach cache, serialize and query. Those are the worst case, several calls deep and usually down an error path, not what a normal call pays.

What one call costs · 16 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost core_auto_updates_settings() can have, taken from its control-flow graph on PHP 8.5.
