2020-09-16Add function to create a fake inode in FUSE integration testCraig Chi
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
2020-09-16Add function generating array of iovec with different FUSE structsCraig Chi
This commit adds a function in the newly created fuse_util library, which accepts a variable number of arguments and data structures. Fixes #3609
2020-09-16Add functions in FUSE integration test to get metrics from FUSE serverCraig Chi
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
2020-09-16Extend integration test to test sequence of FUSE operationCraig Chi
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

2020-08-10Implement FUSE_GETATTRCraig Chi
FUSE_GETATTR is called when a stat(2), fstat(2), or lstat(2) is issued from VFS2 layer to a FUSE filesystem. Fixes #3175

2020-08-04Fix FUSE integration test failed with ECONNREFUSEDCraig Chi
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

2020-08-04Add FUSE integration testCraig Chi
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
