It absorbed lessons from many sources along the way.
Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language There are no significant changes to the language specification.
A corner case involving shifts of untyped constants has been clarified, and as a result the compilers have been updated to allow the index expression x[1. The grammar for method expressions has been updated to relax the syntax to allow any type expression as a receiver; this matches what the compilers were already implementing.
Read is a valid, if unusual, method expression that the compilers already accepted and is now permitted by the language grammar.
Ports There are no new supported operating systems or processor architectures in this release. Most of the work has focused on strengthening the support for existing ports, in particular new instructions in the assembler and improvements to the code generated by the compilers.
As announced in the Go 1.
The arm port is still broken. This allows binary distributions to be unpacked anywhere in the file system and then be used without setting GOROOT explicitly.
Modification times are no longer consulted or relevant. The old advice to add -a to force a rebuild in cases where the modification times were misleading for one reason or another for example, changes in build flags is no longer necessary: If you observe otherwise, please file a bug.
For more details, see go help build. The effect of the cache should be to speed builds that do not explicitly install packages or when switching between different copies of source code for example, when changing back and forth between different branches in a version control system.
The old advice to add the -i flag for speed, as in go build -i or go test -i, is no longer necessary: For more details, see go help cache. The new build cache makes future commands still run as quickly as if the dependencies had been installed.
To force the installation of dependencies, use the new go install -i flag. Installing dependency packages should not be necessary in general, and the very concept of installed packages may disappear in a future release.
One new requirement implied by these changes is that binary-only packages must now declare accurate import blocks in their stub source code, so that those imports can be made available when linking a program using the binary-only package. For more details, see go help filetype.
Any such problems are treated like build errors and prevent execution of the test. Only a high-confidence subset of the available go vet checks are enabled for this automatic check. The go test -coverpkg flag now interprets its argument as a comma-separated list of patterns to match against the dependencies of each test, not as a list of packages to load anew.
Also, the go test -coverprofile option is now supported when running multiple tests. In case of failure due to timeout, tests are now more likely to write their profiles before exiting.
In past releases, go test only applied this merging most of the time. The new go test -failfast flag disables running additional tests after any test fails.
Note that tests running in parallel with the failing test are allowed to complete. Finally, the new go test -json flag filters test output through the new command go tool test2json to produce a machine-readable JSON-formatted description of test execution. This allows the creation of rich presentations of test execution in IDEs and other tools.
For more details about all these changes, see go help test and the test2json documentation. This closes a security hole in which a downloaded package uses compiler options like -fplugin to run arbitrary code on the machine where it is being built.This creates two different files; a C/C++ source file example_wrap.c or initiativeblog.com and numerous Java files.
The generated C/C++ source file contains the JNI wrapper code that needs to be compiled and linked with the rest of your C/C++ application. The Java Secure Socket Extension (JSSE) enables secure Internet communications.
It provides a framework and an implementation for a Java version of the SSL and TLS protocols and includes functionality for data encryption, server authentication, message integrity, . Aug 06, · Today we released the final version of Team Foundation Server TFS is a major step forward, with tons of improvements throughout the development process but with special emphasis on DevOps capabilities.
In this tutorial we will create a small hello world application using Spring MVC in Eclipse and Tomcat.
We will learn about different spring annotations @Controller, @RequestMapping and also how to configure Spring in web xml. Java IntelliJ IDEA brings support for the upcoming Java The IDE now supports local-variable syntax for lambda parameters according to the JEP , so you can use the var keyword in lambda expressions..
