由 家住魔仙堡 提交于 2019-12-10 23:50:03
问题 We have an spring application which dynamically loads components based in the lib folder. This application needs to be deployed on different AS, like Jetty,Tomcat,JBoss.. Now, JBoss has this VFS feature, where it does not really unpack your war it seems, and uses vfs:// for files inside the war/jar.. Currently we are in the process of upgrading (from Java6) to Java7, and we encounter the following problem. First of all, snowdrop 1.0.0GA no longer works under Java7, because the InputStream was

How to construct an in-memory virtual file system and then write this structure to disk

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-10 17:35:37
问题 I'm looking for a way to create a virtual file system in Python for creating directories and files, before writing these directories and files to disk. Using PyFilesystem I can construct a memory filesystem using the following: >>> import fs >>> dir = fs.open_fs('mem://') >>> dir.makedirs('fruit') SubFS(MemoryFS(), '/fruit') >>> dir.makedirs('vegetables') SubFS(MemoryFS(), '/vegetables') >>> with dir.open('fruit/apple.txt', 'w') as apple: apple.write('braeburn') ... 8 >>> dir.tree() ├── fruit

Is it possible to have a Linux VFS cache with a FUSE filesystem?

由 萝らか妹 提交于 2019-12-10 09:44:39
问题 It seems that the Linux VFS cache does not work by default with a FUSE filesystem. For example, the "read" call seems to be systematically forwarded to the FUSE filesystem. I work on a FUSE specific remote filesystem. I need a very aggressive cache. Do I need to implement my own page cache? Or is it possible to activate the Linux VFS cache for this particular FUSE filesystem? Or does someone know a good proxy/cache FUSE filesystem (or a kind of C library to do that without reinventing the

Why can't I open a JBoss vfs:/ URL?

问题 We are upgrading our application from JBoss 4 to JBoss 6. A couple of pieces of our application get delivered to the client in an unusual way: jars are looked up inside of our application and sent to the client from a servlet, where the client extracts them in order to run certain support functions. In JBoss 4 we would look these jars up with the classloader and find a jar:// URL which would be used to read the jar and send its contents to the client. In JBoss 6 when we perform the lookup we

Difference between statvfs() and statfs() system calls?

由 拥有回忆 提交于 2019-12-08 14:37:57
问题 Why do the statfs() and statvfs() calls both exist when they're so similar? Under what circumstances would I prefer one over the other? 回答1: Err, "historical reasons". Originally 4.4BSD defined a statfs() call. Linux later implemented a slightly different call with the same name. Posix standardized it between all freenix and Unix versions by defining statvfs() . statfs() is OS-specific statvfs() is posix-conforming As they all return slightly different structures, later ones to come along can
