“…APIMigrator primarily relates to example-based program transformation techniques (e.g., [1,13,16,18,20,21,23]). APIMigrator differs from some of these techniques [1,16,18,20,21] in that it uses a more general approach to identify when a migration patch is applicable.…”

“…As opposed to A4 [13], APIMigrator identifies migration examples in remote repositories, handles changes in return values, and is able to prioritize migration examples. Finally, unlike Meditor [23], APIMigrator can analyze and compare multiple examples while performing migrations, allowing for prioritizing and using migration patches that are closer to the essence of the required changes. Additionally, our tool also performs differential testing to validate the migrations performed.…”

To provide their functionality, mobile apps interact extensively with the application programming interface (API) of the underlying operating system. Given that this API evolves frequently, app developers are periodically required to migrate API usages in their apps to ensure that the apps behave as expected when running on the new API. To help developers with this tedious, error-prone, and time-consuming task, we defined a technique for automated API migration and implemented it in a tool called APIMigrator that supports Android apps. APIMigrator (1) automatically migrates API usages within an app by leveraging how developers of other apps migrated corresponding API usages and (2) validates the migrations through differential testing. We evaluated APIMigrator on a benchmark of 15 real-world apps and obtained promising results. Overall, our tool was able to migrate 85% of the API usages considered and validate 68% of these migrations. We provide a demo video of the tool at https://youtu.be/v0VfpKi_IDc.

“…Other work [57,58] goes beyond simple replacement of library API calls. Xu et al [57] use syntactic program differencing and program dependency analysis to target actual edits and replacements. Although it is a syntactic rather than semantic approach, they are able to add new code to help migration of libraries.…”

Library migration is a challenging problem, where most existing approaches rely on prior knowledge. This can be, for example, information derived from changelogs or statistical models of API usage.This paper addresses a different API migration scenario where there is no prior knowledge of the target library. We have no historical changelogs and no access to its internal representation. To tackle this problem, this paper proposes a novel approach (M 3 ), where probabilistic program synthesis is used to semantically model the behavior of library functions. Then, we use an SMT-based code search engine to discover similar code in user applications. These discovered instances provide potential locations for API migrations.We evaluate our approach against 7 well-known libraries from varied application domains, learning correct implementations for 94 functions. Our approach is integrated with standard compiler tooling, and we use this integration to evaluate migration opportunities in 9 existing C/C++ applications with over 1MLoC. We discover over 7,000 instances of these functions, of which more than 2,000 represent migration opportunities.

“…For the problem of crosslanguage program translation, much work has utilized various statistical language models for tokens [23], phrases [15,24,25], or APIs [4,8,21,22,28,38,39]. A few studies also used word embedding for API mapping and migration (e.g., [12,13,26,28,35]), but our work does not need large number of manually specified parallel corpora or mapping seeds. Tools for translating code among specific languages in practice (e.g., Java2CSharp [5]) also often dependent on manually defined rules specific to the grammars of individual languages, while our approach alleviates the need of language-specific rules.…”
