The fuse protocol includes a FUSE_INTERRUPT operation that the client can send to the server to indicate that it wants to abort an in-progress operation. It's required to interrupt any syscall that is blocking on a fuse operation. This commit adds basic FUSE_INTERRUPT support. If a process receives any signal while it's blocking on a FUSE operation, it will send a FUSE_INTERRUPT and wait for the original operation to complete. But there is still much to do: * The current code will leak memory if the server ignores FUSE_INTERRUPT, which many do. It will also leak memory if the server completes the original operation before it receives the FUSE_INTERRUPT. * An interrupted read(2) will incorrectly appear to be successful. * fusefs should return immediately for fatal signals. * Operations that haven't been sent to the server yet should be aborted without sending FUSE_INTERRUPT. * Test coverage should be better. * It would be great if write operations could be made restartable. That would require delaying uiomove until the last possible moment, which would be sometime during fuse_device_read. PR: 236530 Sponsored by: The FreeBSD Foundation |

src/tests: The FreeBSD test suite
=================================
To run the FreeBSD test suite:
(1) Make sure that kyua is installed:
pkg install kyua
(2) To run the tests:
kyua test -k /usr/tests/Kyuafile
(3) To see the test results:
kyua report
For further information on using the test suite, read tests(7):
man tests
Description of FreeBSD test suite
=================================
The build of the test suite is organized in the following manner:
* The build of all test artifacts is protected by the MK_TESTS knob.
The user can disable these with the WITHOUT_TESTS setting in
src.conf(5).
* The goal for /usr/tests/ (the installed test programs) is to follow
the same hierarchy as /usr/src/ wherever possible, which in turn drives
several of the design decisions described below. This simplifies the
discoverability of tests. We want a mapping such as:
/usr/src/bin/cp/ -> /usr/tests/bin/cp/
/usr/src/lib/libc/ -> /usr/tests/lib/libc/
/usr/src/usr.bin/cut/ -> /usr/tests/usr.bin/cut/
... and many more ...
* Test programs for specific utilities and libraries are located next
to the source code of such programs. For example, the tests for the
src/lib/libcrypt/ library live in src/lib/libcrypt/tests/. The tests/
subdirectory is optional and should, in general, be avoided.
* The src/tests/ hierarchy (this directory) provides generic test
infrastructure and glue code to join all test programs together into
a single test suite definition.
* The src/tests/ hierarchy also includes cross-functional test programs:
i.e. test programs that cover more than a single utility or library
and thus don't fit anywhere else in the tree. Consider this to follow
the same rationale as src/share/man/: this directory contains generic
manual pages while the manual pages that are specific to individual
tools or libraries live next to the source code.
In order to keep the src/tests/ hierarchy decoupled from the actual test
programs being installed --which is a worthy goal because it simplifies
the addition of new test programs and simplifies the maintenance of the
tree-- the top-level Kyuafile does not know which subdirectories may
exist upfront. Instead, such Kyuafile automatically detects, at
run-time, which */Kyuafile files exist and uses those directly.
Similarly, every directory in src/ that wants to install a Kyuafile to
just recurse into other subdirectories reuses this Kyuafile with
auto-discovery features. As an example, take a look at src/lib/tests/
whose sole purpose is to install a Kyuafile into /usr/tests/lib/.
The goal in this specific case is for /usr/tests/lib/ to be generated
entirely from src/lib/.
