问题 Given a snapshot of an existing redis database in a dump.rdb (or in .json format) file, I want to restore this data in my own machine to run some tests on it. Any pointers on how to do this would be greatly appreciated. I have resorted to trying to parse the data in the dump.rdb and then save it in a redis DB manually. I feel like there is/should be a cleaner way. 回答1: If you want to restore the entire file, simply copy it to the right directory specified in redis.conf and restart redis

问题 I am using Symfony 4 on PHP 7.1.14 with Xdebug enabled and html_errors=on . When I use {{ dump() }} function in my twig, data printed on the screen is hard to read because of poor Xdebug formatting (ugly dump). It's also not dumping objects, which is necessary in my case (I see them as an object and can't see their properties). I remember using this function in Symfony 3 with PHP 7.0.13 and the output was presented as the cool black area with foldable data (cool dump). All PHP options and

问题 I am trying to do a forced java thread dump programmatically, just like the command jstack -F -l <PID> would do it. My best attempt: I created a subclass from sun.jvm.hotspot.tools.JStack overwriting run() with the following code analogous to sun.jvm.hotspot.tools.JStack.run() but in the last line calling start(printstream) instead of start() : StackTrace stacktrace = new StackTrace(mixedMode, concurrentLocks); try { Class<?> stacktraceTool = stacktrace.getClass().getSuperclass(); Method

问题 I have a multi-threaded C++ program that deadlocks in some rare cases. The problem is hard to reproduce and I can only reproduce it in a remote machine. The method I want to use for solving this problem is run the program wait for deadlock send abort signal to it for generating core dump copy the dump back to my local machine use gdb to debug it I do not have gdb on the remote machine and cannot install anything on it.

问题 I need a dump of a svn repository. I found two solutions svnrdump dump And svnadmin dump svnrdump dump is the same of svnadmin dump ? If not, what are the differences between these two commands ? 回答1: svnrdump generates the same dump as svnadmin dump . According to the red book: The svnrdump program is, to put it simply, essentially just network-aware flavors of the svnadmin dump and svnadmin load subcommands, rolled up into a separate program. The only difference between the two is that
