Writing distributed and parallel applications is rather
difficult. Because of this difficulty, many bugs appear during
development and frequently, on deployed applications. Classical
debugging techniques are not enough anymore because of the
non-determinism induced by this kind of applications. Record and
replay techniques have been created in order to help developers. These
techniques are composed by two main phases. The record phase captures
all non-deterministic events of the execution. Then, during the replay
phase, the original execution can be repeated in order to find the
causes of the bugs. Unfortunately, tracing all non-deterministic
events introduces a large overhead. This thesis presents Symber,
a record and replay tool for multithreaded Java applications that
combines partial logging with an inference mechanism based on symbolic
execution. Thus, Symber is able to reduce the overhead introduced by
only logging the local execution path and the order in which the locks
are acquired. Our results demonstrate that Symber produces a
competitive overhead in comparison to other tech- niques and still
maintains the ability to efficiently replay concurrency bugs.
