HotSWUp 2009: Second ACM Workshop on Hot Topics in Software Upgrades

(co-located with OOPSLA 2009)
Orlando, Florida
October 25, 2009


The goal of HotSWUp is to identify cutting-edge research ideas for
implementing software upgrades. Software must be upgraded regularly
to incorporate bug fixes and security patches or to keep up with the
evolving requirements. Whether upgrades are applied offline or online,
they significantly impact the software's performance and reliability.
Recent studies and a large body of anecdotal evidence suggest that,
in practice, upgrades are failure-prone, tedious, and expensive.

HotSWUp is an interdisciplinary workshop, based on synergies among
the areas of programming languages (e.g., as reflected at
conferences such as OOPSLA or PLDI), software engineering (e.g., as
reflected at ICSE or FSE) and systems (e.g., as reflected at SOSP or
OSDI). By seeking contributions from both academic researchers and
industry practitioners, HotSWUp aims to combine novel ideas
with experience from upgrading real systems. The workshop builds on
the success of HotSWUp'08, where the paper presentations and lively
discussions attracted a diverse audience of researchers.

The topics of interest include, but are not limited to:

- Programming language / operating system / database support for
software upgrades.
- Improving the reliability of upgrades (e.g., support for upgrade
validation and for rollback after failures).
- Support for system restructuring (e.g., evolving APIs, changes to
database schemas).
- Identifying dependencies between components and guaranteeing safe
interactions among mixed versions.
- Coordinating and disseminating upgrades in large-scale distributed
- Tools for preparing, testing, and applying software upgrades.
- Human factors in software upgrades (e.g., usability of upgrading
tools, common operator mistakes).


We solicit position papers that fall into one of the following categories:

- Suggest how a successful approach can be applied in a different context
(e.g., static dependency analysis applied to distributed-system upgrades).
- Refute an old assumption about software upgrades (e.g., by presenting
negative results).
- Describe a new problem or propose a novel solution to an old problem.
- Present empirical evidence related to the practical implementation of
software upgrades.

Papers must not exceed 5 pages, in the ACM SIGPLAN 10 point format, and must
be submitted electronically at The workshop proceedings
will be published in the ACM Digital Library.
