Techniques for dealing with non-determinism and concurrency issues in monitoring a concurrent component-based system are also discussed.
A new wave of compilers are starting to make serious inroads in eliminating concurrency issues and security issues.
Nonetheless, synthesising an adaptor compliant with a given contract is not an easy task where concurrency issues must be kept in mind and security attacks must be analysed and prevented.
(2) Similarly, only a small share of bugs are unreproducible and related to concurrency issues (2%).
Answer RQ1: Only 4% of the total set of bugs are related to concurrency issues, while the majority of bugs (i.e., 96%) are of non-concurrency type.
Our results indicate that a relatively small share of bugs is related to concurrency issues, while the vast majority are non-concurrency bugs.
A bug with at least one keyword related to concurrency issues is categorized as Concurrency keywords matched, some of these bugs are fixed and closed and others are unreproducible.
Answer RQ2: The fraction of unreproducible bugs from the total set of bugs is only 4% while 2% of the total set are unreproducible and related to concurrency issues.
As seen in Fig. 4, out of the 9169 reported bugs in the projects' databases, 351 (i.e., ∼4%) bugs are related to concurrency issues and are causing a certain type of concurrency bug while the rest (i.e., ∼96%) are identified as non-concurrency bugs.
Collaboratively creating experimental data is significantly more convenient in web-based applications, as concurrency issues, such as file locks, can be avoided.
This type of data items are usually implemented as a property, unless there are some performance or concurrency issues that makes it necessary to keep a copy of the data within the object itself.
