948-951: The updated documentation for theLocalsmethod is clear and informative.It effectively explains the scope and lifecycle of stored variables, including the automatic removal and closure of resources implementing
io.Closer. The tip about using non-exported types as keys to avoid collisions is a valuable addition for best practices.
962-962: The example code effectively demonstrates the use of non-exported types as keys and type assertions.This is a practical example that not only shows how to use the
Localsmethod but also reinforces the documentation on preventing key collisions and ensuring type safety.Also applies to: 969-976

862-880: Clarify the behavior ofLocalsmethods regardingio.Closer.The documentation added to the
Localsmethods clearly explains the lifecycle of stored values, including the automatic removal and the invocation of theClosemethod for values implementingio.Closer. This is a crucial detail for proper resource management and helps prevent resource leaks.

948-951: Enhanced documentation forctx.Localsclarifies lifecycle and type safety.The updated documentation clearly explains the lifecycle of stored variables and the importance of type assertions, which improves the understanding and correct usage of the
ctx.Localsmethod.
960-960: Updated example code demonstrates best practices for handling keys and type assertions.The example code effectively demonstrates the use of non-exported types for keys to avoid collisions and the proper way to perform type assertions. This is a valuable update for preventing common errors and ensuring data integrity.

177-180: The documentation added to theLocalsmethod clearly explains the lifecycle of stored values and their cleanup process. However, consider a slight grammatical adjustment for clarity.- // All the values are removed from ctx after returning from the top - // RequestHandler. Additionally, Close method is called on each value - // implementing io.Closer before removing the value from ctx. + // All values are removed from ctx after returning from the top + // RequestHandler. Additionally, the Close method is called on each value + // that implements io.Closer before the value is removed from ctx.
Description
Improve the
ctx.Localsdocumentation to clarify the behavior of stored variables and their lifecycle to avoid unintentional resource closures, and provide best practices with keys and values.Changes Introduced
io.Closerinterface, itsClosemethod will be called before it's removed.Details
docs/api/ctx.mdandctx.goLocalsmethod documentation.ctx.Localsregarding variable removal andio.Closerinterface handling.These changes aim to prevent issues with unintentional resource closures, such as database connections, and enhance the clarity and safety of using
ctx.Localsinfiber.
