This patch is just for review. It enables FUSE support in the API via two new calls, 'guestfs_mount_local' and 'guestfs_umount_local'. FUSE turns out to be very easy to deadlock (necessitating that the machine be rebooted). Running the test from the third patch is usually an effective way to demonstrate this. However I have not yet managed to produce a simple reproducer that

This changes the proposed API slightly. Previously 'mount-local' generating a 'mounted' event when the filesystem was ready, and from the 'mounted' event you had to effectively do a fork. Now, 'mount-local' just initializes the mountpoint and you have to call 'mount-local-run' to enter the FUSE main loop. Between these calls you can do a fork or whatever

This version doesn't crash or cause hung processes or stuck mountpoints, so that's an improvement. Rich.

The 'localmountpoint' variable in the handle is available only when building with FUSE support, so guard it in a proper #ifdef block.

Recently i deployed latest 1.17.40 on rhel6.1. When i ran a tiny program which was to test the function guestfs_mount_local() or those similar functions that mounts locally, Error prompted?undefined symbol guest_mount_local ! Why didn`t this undefined symbol error prompt when the program was first compiled,but occurred when it was run? Then i gave guestfish mount local a try in the shell, and

Thank you Rich, I checked the version and found that it printed an old 1.17.17 version which was deployed before. But I remembered i did check the version in guestfish shell and it said 1.17.40 before that?then i totally ignored the fact i had another version involved. I`ve changed the LD_LIBRARY_PATH and the "undefined symbol" error disappeared.But some "inspection API not

Hi I`ve been trying this guestfs_mount_local api for quite a few days, but still can`t get over it. Now it seems to have enter the fuse loop but have some problems with 'mount'? and stops at guestfs_mount_local_run(g). Here`s corresponding code in the test program: ?? if(guestfs_mount_local(g,"/mnt/libg")==-1) exit(EXIT_FAILURE); else guestfs_mount_local_run(g); ?? Below is a

the 'hivex' had been installed actually, hivex.x86_64 0:1.2.4-3.el6 and perl-hivex.x86_64 0:1.2.4-3.el6, however it just could not be detected.Maybe i should compile one rather than just yum. I`m not familiar with hivex,as far as i know, it can be used to modify windows registry, but why the inspection API had been binded with hivex when we might use inspection api solely with linux os

[These two patches are for discussion only] Allow FUSE support to be used directly through the API. This is the second commit. In order to make this usable from guestfish, we have to also bind the events API in guestfish. This is the first commit. Rich.

Because of previous automated commits, such as changing 'guestfs___' -> 'guestfs_int_', several function calls no longer lined up with their parameters, and some lines were too long. The bulk of this commit was done using emacs batch mode and the technique described here: http://www.cslab.pepperdine.edu/warford/BatchIndentationEmacs.html The changes suggested by emacs were

Thanks a lot. I was trying to copy on local disk and guestfs_download () solved my problem. Now I am trying to modify source code of guestfs_download () to extract file in memory. Can you guide me what should i do to achieve that. Mohsin On Fri, Feb 10, 2017 at 2:13 AM, Richard W.M.
