With the patch request option you may order a correction of some particular problem that can be found in Open CASCADE. You may decide to use this option when work-around is not available or you prefer the most efficient solution.
Corrections of all submitted problem from all support clients, as well as custom development and internal R&D projects are collected and are delivered in the nearest release. This can be either maintenance release (version x.y.z) exclusively available to the clients or publicly available minor (x.y) or major (x.0) release. The latter accumulate all modifications introduced in the intermediate maintenance releases.
Upon submitting the problem you receive a unique ID, under which the request (a bug or an improvement) has been registered in the global tracking tool – Bugzilla. You may always contact the Customer Support manager to consult on the progress of your registered request. Moreover, Release Notes accompanying every Open CASCADE release include an exhaustive enumeration of all corrections made therein. Thus, you can easily find out whether your problem has been completely fixed.
Correction of a problem includes not only debugging and modification of the source code but also involves all certification tasks. These include enriching existing database with a new test case, making source code portable and running non-regression tests on all supported platforms. Such quality assurance approach will guarantee the problem will not appear in the future versions of Open CASCADE. In addition, with recent improvement of internal certification process, majority of corrections now result in further updates of technical documentation. This ensures on-going quality growth of the product delivered in every release.
Patch request is available as an option within a-la carte programs. Consider that one patch corrects one bug.
