Initialization safety

摘要

Embodiments of the disclosure are directed to inserting a declaration of a non-overwritable variable pointing to a current object in a source code, and inserting a code of storing a value referencing the current object to the non-overwritable variable. Embodiments of the disclosure are directed to converting a source code to generate a shared object in a lock-free mode by inserting a declaration of a non-overwritable variable pointing to a current object in the source code, and inserting a code of storing a value referencing the current object to the non-overwritable variable.

主权项

1. A system, comprising:
at least one processor configured to execute a plurality of threads, where each thread of the plurality of threads is configured to access an object in a lock-free mode based on an insertion of a declaration of a non-overwritable variable pointing to a current object in a source code and a storage of a value referencing the current object to the non-overwritable variable; wherein a first thread of the plurality of threads, when executed by the at least one processor, causes the system to:
lock a shared list;allocate the object;modify a value of the object; andput the object corresponding to the modified value at a head of the shared list.
