Don't propagate arbitrary golang errors up from fusefs because errors
that don't map to an errno result in a sentry panic.

This commit implements FUSE_SETATTR command. When a system call modifies
the metadata of a regular file or a folder by chown(2), chmod(2),
truncate(2), utime(2), or utimes(2), they should be translated to
corresponding FUSE_SETATTR command and sent to the FUSE server.
Fixes#3332
According to Linux 4.4's FUSE behavior, the flags and fh attributes in
FUSE_GETATTR are only used in read, write, and lseek. fstat(2) doesn't
use them either. Add tests to ensure the requests sent from FUSE module
are consistent with Linux's.
Updates #3655
Adds a function for the testing thread to set up a fake inode with a
specific path under mount point. After this function is called, each
subsequent FUSE_LOOKUP request with the same path will be served with
the fixed stub response.
Fixes#3539
This commit adds 3 utility functions to ensure all received requests
and preset responses are consumed.
1. Get number of unconsumed requests (received by the FUSE server but
not consumed by the testing thread).
2. Get number of unsent responses (set by the testing thread but not
processed by the FUSE server).
3. Get total bytes of the received requests (to ensure some operations
don't trigger FUSE requests).
Fixes#3607
Original FUSE integration test has limited capabilities. To test more
situations, the new integration test framework introduces a protocol
to communicate between testing thread and the FUSE server. In summary,
this change includes:
1. Remove CompareResult() and break SetExpected() into
SetServerResponse() and GetServerActualRequest(). We no longer set
up an expected request because we want to retrieve the actual FUSE
request made to the FUSE server and check in the testing thread.
2. Declare a serial buffer data structure to save the received requests
and expected responses sequentially. The data structure contains a
cursor to indicate the progress of accessing. This change makes
sequential SetServerResponse() and GetServerActualRequest() possible.
3. Replace 2 single directional pipes with 1 bi-directional socketpair.
A protocol which starts with FuseTestCmd is used between the testing
thread and the FUSE server to provide various functionality.
Fixes#3405
The newer version of FUSE_INIT checks the response from the FUSE server
if its major number is equal to 7. If it's not, then FUSE_INIT fails and
further filesystem operations will get ECONNREFUSED. To mitigate this
issue, we can send back a response with major version equals to 7 when
consuming the first FUSE_INIT request.
Fixes#3500
This commit adds an integration test framework for FUSE support. Please
refer to the test example and test/fuse/README.md for further details.
Fixes#3098
