问题 I have created Google Cloud Storage Bucket and mounted it to my VM using: gcsfuse my-bucket /path/to/mount/point When I type df -H its listed as mounted filesystem. I have the following issue: If I upload file to the bucket using the GCP web console I can see it from the VM. If I try to create a directory however from the VM to the mounted file system mkdir /path/to/mount/point/test it says: mkdir: cannot create directory ‘/path/to/mount/point/test’: Input/output error 回答1: I found the cause.

问题 I have a application which places message in JMS Queue.The message size can be upto 150 mb. JMS message contains byte array data with additional metadata as xml,once the message is placed in queue the camel route application picks the message and calls the external java api with the message.i would like to stream the message from the JMS Queue using camel jms component. Can you please tell me if i can acheive it using camel. Currently i am facing heap error issue. Sample JMS message is as

What is happening when this code calls FUSE like this?

问题 I am working through another person's implementation of file system with python fuse. I am trying to understand the flow of the program. When the code's main method is called it somehow calls the listDirectory method. Where is the code for this FUSE method defined? Where can I find documentation of what is happening? I searched the fuse.py file for this method and can't find it. def listDirectory(): print '[*] Listing Directory' message = str({"RequestType":4}) print "sending message " +

How to initialize a struct using the c style while using the g++ compiler?

主宰稳场 提交于 2019-12-10 18:24:50
问题 Generally, in order to initialize a struct in c, we could only specify part of the fields. Like below: static struct fuse_operations hello_oper = { .getattr = hello_getattr, .readdir = hello_readdir, .open = hello_open, .read = hello_read, }; However, in C++, we should initialize the variables in the struct without naming the fields. Now, what if I would like to initialize a struct using the c style while using the g++ compiler, how to accomplish this? PS: the reason I need to do this is that

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

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

Possible to run multiple main loops?

我的梦境 提交于 2019-12-09 16:48:22
问题 I'm working with both libfuse and the glib event interface and I've run into an issue where I need to run multiple main loops concurrently (glib's g_main_loop_run and fuse_loop_mt ). I've already attempted to created a detached thread for glib's event loop under a secondary context, e.g.: static void * event_loop(void *arg) { GMainLoop *event_loop; GMainContext *context; context = g_main_context_new(); g_main_context_push_thread_default(context); event_loop = g_main_loop_new(context, FALSE);

Use libfuse in a project, without root access (for installation)? FTP mounts & inotify/kqueue/FSEvents

拈花ヽ惹草 提交于 2019-12-08 08:29:29
I'd like my application to be able to show a directory listing from a remote FTP (or SFTP etc) location. When a file/directory changes in the remote directory tree, the application should update its view with the relevant changes. Because traversing the entire tree is slow and wasteful, I'd like to use something along the lines of FSEvents (inotify/kqueues on Linux), but obviously these libraries are filesystem-based, and a connection to an FTP server is not the same as a mounted filesystem. In order to make these libraries work, I'd need to actually mount a filesystem backed by FTP/SFTP on

what is recvmsg equivalent in python?

限于喜欢 提交于 2019-12-08 07:52:40
问题 I am implementing a python script to do fuse mount programatically. I have written an equivalent in C, by making use of socketpair and recvmsg api's. But in python recvmsg is not implemented, so I am stuck. Can anyone of you tell me a python equivalent of this? Any help would be appreciated. Let me tell why do I need recvmsg, I require to send the fd of the fuse mount from the child to the parent. 回答1: What you could look at is using pyx or a C module for Python that implements the required

Trying to use Fuse to mount HDFS. Can't compile libhdfs

问题 I'm attempting to compile libhdfs (a native shared library that allows external apps to interface with hdfs). It's one of the few steps I have to take to mount Hadoop's hdfs using Fuse. The compilation seems to go well for a while but finishes with "BUILD FAILED" and the following problems summary - commons-logging#commons-logging;1.0.4: configuration not found in commons-logging#commons-logging;1.0.4: 'master'.
