DeepAnalyze: Learning to Localize Crashes at Scale [article]

Manish Shetty, Chetan Bansal, Suman Nath, Sean Bowles, Henry Wang, Ozgur Arman, Siamak Ahari
2021 arXiv   pre-print
The analysis provides valuable insights on where and how the crashes happen and what methods to blame for the crashes.  ...  crashes of the same applications, but also bootstraps crash localization for other applications with zero to very little additional training data.  ...  Prior work in crash analysis has heavily focused on crash bucketization [14, 16, 54] . But, in order to do effective bucketization, crash localization is critical. Wu et al.  ...

Dalí: A Periodically Persistent Hash Map

Faisal Nawab, Joseph Izraelevitz, Terence Kelly, Charles B. Morrey III, Dhruva R. Chakrabarti, Michael L. Scott, Marc Herbstritt
2017 International Symposium on Distributed Computing  
To guarantee forward progress, we periodically force a write-back of all dirty data in the cache, ensuring that all "sufficiently old" updates have indeed become persistent, at which point they become semantically  ...  In the era that follows a crash, the visible content of each bucket (the records that will be seen by an initial read or update) will be precisely the valid content of that bucket.  ...  A trivial induction (starting with initially empty content) shows that this prepending operation preserves both well formedness and the desired sequential semantics.  ...

So there is a great need of a structured mining algorithm - where given a crash log, the existing bug database could be mined to find out the class to which the bug should be allocated.  ...  number of buckets with the goal that no two buckets contain error reports from the same bug.  ...  Consider the following data taken from the crash report of a bug.  ...

Aion: Better Late than Never in Event-Time Streams [article]

Sérgio Esteves, Gianmarco De Francisci Morales, Rodrigo Rodrigues, Marco Serafini, Luís Veiga
2020 arXiv   pre-print
In particular, we introduce a proactive caching scheme, where we leverage the semantics of stream processing to anticipate the need for bringing data to memory.  ...  However, current systems maintain this state in memory, which either imposes a maximum period of tolerated lateness, or causes the system to degrade performance or even crash when the system memory runs  ...  Data Transfer Policies The choice of the timing of data transfers between the m-bucket and the p-bucket takes into consideration the semantics of the streaming application.  ...

Automatic and scalable fault detection for mobile applications

Lenin Ravindranath, Suman Nath, Jitendra Padhye, Hari Balakrishnan
2014 Proceedings of the 12th annual international conference on Mobile systems, applications, and services - MobiSys '14  
The techniques in VanarSena are driven by a study of 25 million real-world crash reports of Windows Phone apps reported in 2012.  ...  VanarSena runs on cloud servers: the developer uploads the app binary; VanarSena then runs several app "monkeys" in parallel to emulate user, network, and sensor data behavior, returning a detailed report of crashes  ...  Together, these buckets represent around 48% of crashes in the top 100 buckets (and 35% of all crashes); the number of unique root causes for these buckets is 8.  ...

Obladi: Oblivious Serializable Transactions in the Cloud [article]

Natacha Crooks and Matthew Burke and Ethan Cecchetti and Sitar Harel and Rachit Agarwal and Lorenzo Alvisi
2018 arXiv   pre-print
Assume the encryption scheme used in Π Ob is semantically secure and the MACs are existentially unforgeable.  ...  Modeling Crashes In the real system the proxy can crash at any time.  ...  As all data is encrypted, the only difference between H 1 and H 2 is the contents of the ciphertexts, and by assumption the encryption scheme is semantically secure.  ...

Bridging the programming gap between persistent and volatile memory using WrAP

Ellis Giles, Kshitij Doshi, Peter Varman
2013 Proceedings of the ACM International Conference on Computing Frontiers - CF '13  
Note that partially written buckets that were not attached to the Log at the time of system crash can be safely discarded, since their transactions are treated as not having completed.  ...  Copy-on-write semantics trigger the copying of a block that need to be updated.  ...

Distributed programming in Argus

1988 Communications of the ACM  
(Argus is an extension of the CLU language [15] , and most of its syntax and semantics is taken from CLU.)  ...  It prevents other calls that use the same bucket because it acquires a write lock on the bucket (when it assigns to the ith element of the bucket).  ...

Fast crash recovery in RAMCloud

Diego Ongaro, Stephen M. Rumble, Ryan Stutsman, John Ousterhout, Mendel Rosenblum
2011 Proceedings of the Twenty-Third ACM Symposium on Operating Systems Principles - SOSP '11  
RAMCloud is a DRAM-based storage system that provides inexpensive durability and availability by recovering quickly after crashes, rather than storing replicas in DRAM.  ...  approach will scale to recover larger memory sizes (64 GB or more) in less time with larger clusters. • Harnessing scale: RAMCloud takes advantage of the system's large scale to recover quickly after crashes  ...  However, H-Store is focused more on achieving full RDBMS semantics and less on achieving large scale or low latency to the same degree as RAMCloud.  ...

Putting Randomized Compiler Testing into Production (Experience Report)

Alastair F. Donaldson, Hugues Evrard, Paul Thomson, Tobias Pape, Robert Hirschfeld
2020 European Conference on Object-Oriented Programming  
We wrote several ad-hoc scripts to classify variants that caused crashes into unique "buckets", so that each bucket represents a unique bug (based on the top function name in the stack trace).  ...  No valid shader should not cause a driver crash, so there is no need to keep a semantic equivalence with the reference shader.  ...

Fast Nonblocking Persistence for Concurrent Data Structures [article]

Wentao Cai, Haosen Wen, Vladimir Maksimovski, Mingzhe Du, Rafaello Sanna, Shreif Abdallah, Michael L. Scott
2021 arXiv   pre-print
Like its predecessor, nbMontage is buffered durably linearizable: it guarantees that the state recovered in the wake of a crash will represent a consistent prefix of pre-crash execution.  ...  Unlike its predecessor, nbMontage ensures wait-free progress of the persistence frontier, thereby bounding the number of recent updates that may be lost on a crash, and allowing a thread to force an update  ...  In the wake of a crash, threads ignore nodes prepended to hash bucket lists during the two most recent epochs. No other writes-back or fences are required. Cohen et al.  ...

It also arranges to persist only that data minimally required to reconstruct the structure after a crash.  ...  If a crash occurs in epoch e, all work performed in epochs e and e-1 is lost, but work from prior epochs is preserved.  ...  The Montage queue employs a single lock; the Montage hash map has a lock per bucket.  ...
