Alan Somers aef22f2d75 fusefs: correctly handle short reads A fuse server may return a short read for three reasons: * The file is opened with FOPEN_DIRECT_IO. In this case, the short read should be returned directly to userland. We already handled this case correctly. * The file was truncated server-side, and the read hit EOF. In this case, the kernel should update the file size. Fixed in the case of VOP_READ. Fixing this for VOP_GETPAGES is TODO. * The file is opened in writeback mode, there are dirty buffers past what the server thinks is the file's EOF, and the read hit what the server thinks is the file's EOF. In this case, the client is trying to read a hole, and should zero-fill it. We already handled this case, and I added a test for it. Sponsored by: The FreeBSD Foundation		2019-06-21 21:44:31 +00:00

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/.
