随着Undo发布Live Recorder 5.0,这使得在多进程系统上的调试变得更加轻松。

随着Undo发布Live Recorder 5.0,Linux调试迈出了一大步。该产品于上个月发布,这使得在多进程系统上的调试变得更加轻松。它基于飞行记录仪技术(飞行记录仪技术) ,它更加深入进程之中,以深入了解每个进程的情况。这包括内存,线程,程序流,服务调用等。为了实现这一目标,Live Recorder 5.0的记录,重放和调试功能都得到了增强,能够:

记录进程更改共享内存变量的确切顺序。甚至可以针对特定变量并在任何进程中跳转到最后修改该变量的一行。通过随机化线程执行来暴露潜在缺陷,以帮助揭示竞态,崩溃和其他多线程缺陷。记录并重放单个Kubernetes和Docker容器的执行,以帮助在微服务环境中更快地解决缺陷。

Undo Live Recorder使工程团队能够记录和重放任何软件程序的执行,而无论软件多么复杂。并且可以诊断和修复测试或生产中问题的根本原因。

XXDepending on your license, Live Recorder can use the live-record command on the command line, but is somewhat similar to strace, but instead of printing system calls and signals, it creates an "Undo Record". Then you can debug the capture failures in the recording (far more efficient than analyzing the core dump!). These recordings can also be shared with other workers and can be replayed using a reversible debugger to further investigate the cause of the crash or other issues.

The Undo engine supports the following Linux distributions:

Red Hat Enterprise Linux 6.8, 6.9, 6.10, 7.4, 7.5, 7.6, and 8.0 Fedora 28, 29, and 30SuSE Linux Enterprise Server 12.3, 12.4, and 15 Ubuntu 16.04 LTS, 18.04 LTS, 18.10, and 19.04

Undo is a fast-growing, venture capital-backed technology startup with headquarters in San Francisco and Cambridge, UK. They claim that Live Recorder can determine 100% of the factors that cause any software failure even in the most complex software environments.
