    University of São Paulo Institute of Mathematics and Statistics Bachelor of Computer Science Improving Parallelism in git-grep Matheus Tavares Bernardino Final Essay [v2.0] mac 499 - Capstone Project Program: Computer Science Advisor: Prof. Dr. Alfredo Goldman São Paulo January 19, 2020 Abstract Matheus Tavares Bernardino. Improving Parallelism in git-grep. Capstone Project Report (Bachelor). Institute of Mathematics and Statistics, University of São Paulo, São Paulo, 2019. Version control systems have become standard use in medium to large software development. And, among them, Git has become the most popular (Stack Exchange, Inc., 2018). Being used to manage a large variety of projects, with dierent magnitudes (in both content and history sizes), it must be build to scale. With this in mind, Git’s grep command was made parallel using a producer-consumer mechanism. However, when operating in Git’s internal object store (e.g. for a search in older revisions), the multithreaded version became slower than the sequential code. For this reason, threads were disabled in the object store case. The present work aims to contribute to the Git project improving the parallelization of the grep command and re-enabling threads for all cases. Analyzes were made on git-grep to locate its hotspots, i.e. where it was consumming the most time, and investigate how that could be mitigated. Between other ndings, these studies showed that the object decompression rou- tines accounted for up to one third of git-grep’s total execution time. These routines, despite being thread-safe, had to be serialized in the rst threaded implementation, because of the surrouding thread-unsafe object reading machinery.

  • Git Patch Operation
    GGIITT -- PPAATTCCHH OOPPEERRAATTIIOONN http://www.tutorialspoint.com/git/git_patch_operation.htm Copyright © tutorialspoint.com Patch is a text file, whose contents are similar to Git diff, but along with code, it also has metadata about commits; e.g., commit ID, date, commit message, etc. We can create a patch from commits and other people can apply them to their repository. Jerry implements the strcat function for his project. Jerry can create a path of his code and send it to Tom. Then, he can apply the received patch to his code. Jerry uses the Git format-patch command to create a patch for the latest commit. If you want to create a patch for a specific commit, then use COMMIT_ID with the format-patch command. [jerry@CentOS project]$ pwd /home/jerry/jerry_repo/project/src [jerry@CentOS src]$ git status -s M string_operations.c ?? string_operations [jerry@CentOS src]$ git add string_operations.c [jerry@CentOS src]$ git commit -m "Added my_strcat function" [master b4c7f09] Added my_strcat function 1 files changed, 13 insertions(+), 0 deletions(-) [jerry@CentOS src]$ git format-patch -1 0001-Added-my_strcat-function.patch The above command creates .patch files inside the current working directory. Tom can use this patch to modify his files. Git provides two commands to apply patches git amand git apply, respectively. Git apply modifies the local files without creating commit, while git am modifies the file and creates commit as well. To apply patch and create commit, use the following command: [tom@CentOS src]$ pwd /home/tom/top_repo/project/src [tom@CentOS src]$ git diff [tom@CentOS src]$ git status –s [tom@CentOS src]$ git apply 0001-Added-my_strcat-function.patch [tom@CentOS src]$ git status -s M string_operations.c ?? 0001-Added-my_strcat-function.patch The patch gets applied successfully, now we can view the modifications by using the git diff command.

  • Coordinated Concurrent Programming in Syndicate
    Coordinated Concurrent Programming in Syndicate Tony Garnock-Jones and Matthias Felleisen Northeastern University, Boston, Massachusetts, USA Abstract. Most programs interact with the world: via graphical user interfaces, networks, etc. This form of interactivity entails concurrency, and concurrent program components must coordinate their computa- tions. This paper presents Syndicate, a novel design for a coordinated, concurrent programming language. Each concurrent component in Syn- dicate is a functional actor that participates in scoped conversations. The medium of conversation arranges for message exchanges and coor- dinates access to common knowledge. As such, Syndicate occupies a novel point in this design space, halfway between actors and threads. 1 From Interaction to Concurrency and Coordination Most programs must interact with their context. Interactions often start as re- actions to external events, such as a user’s gesture or the arrival of a message. Because nobody coordinates the multitude of external events, a program must notice and react to events in a concurrent manner. Thus, a sequential program must de-multiplex the sequence of events and launch the appropriate concurrent component for each event. Put differently, these interacting programs consist of concurrent components, even in sequential languages. Concurrent program components must coordinate their computations to re- alize the overall goals of the program. This coordination takes two forms: the exchange of knowledge and the establishment of frame conditions. In addition, coordination must take into account that reactions to events may call for the cre- ation of new concurrent components or that existing components may disappear due to exceptions or partial failures. In short, coordination poses a major prob- lem to the proper design of effective communicating, concurrent components.

These include identity paths refl : a = a (reflexivity of category theory. The propositional equality type becomes proof- equality), inverse paths ! p : b = a when p : a = b (symme- relevant, and acts like paths in a space.

We reformulate patch theory us- suggested several extensions to type theory. One is Voevodsky’s ing the tools of homotopy type theory, and clearly separate formal univalence axiom [16, 34], which describes the path structure of theories of patches from their interpretation in terms of basic revi- the universe (the type of small types).

The v1.5.0.0-234 service patch includes fixes for the following issues: • DT089431 : Virtualize page fails to load data for data sources that have non-standard data types. • DT089433: Selecting a decimal column when virtualizing a table results in an error. • DT089484: Unable to preview tables with non-standard data types. • DT089486: Issues after virtualizing files that have long names. Optionally, this document provides instructions on how to patch down to service Version v1.5.0.0-217. Introduction 1 Applying patches A Red Hat® OpenShift® project administrator can apply patches on a cluster that is connected to the internet or on an air-gapped cluster. Before you begin Required role: To install a patch, you must be an administrator of the project (namespace) where the software is deployed. In this topic, the term software can be either the Cloud Pak for Data control plane or a service. Before you apply patches, ensure that: • The machine from which you will run the commands meets the requirements described in Preparing your installation node. • You have the required information about your Red Hat OpenShift cluster, as described in Collecting information about your cluster from your administrator. • The Data Virtualization service instance is running correctly. All service pods must be running and ready. • You use the same repo.yaml file that you used to deploy Data Virtualization service Version v1.5.0.0-217.
