With the parser rework [1] and run_kernel() rework [2], this allows the parser to print out test results incrementally. Currently, that's held up by the fact that the LineStream eagerly pre-fetches the next line when you call pop(). This blocks parse_test_result() from returning until the line *after* the "ok 1 - test name" line is also printed. One can see this with the following example: $ (echo -e 'TAP version 14\n1..3\nok 1 - fake test'; sleep 2; echo -e 'ok 2 - fake test 2'; sleep 3; echo -e 'ok 3 - fake test 3') | ./tools/testing/kunit/kunit.py parse Before this patch [1]: there's a pause before 'fake test' is printed. After this patch: 'fake test' is printed out immediately. This patch also adds * a unit test to verify LineStream's behavior directly * a test case to ensure that it's lazily calling the generator * an explicit exception for when users go beyond EOF [1] https://lore.kernel.org/linux-kselftest/20211006170049.106852-1-dlatypov@google.com/ [2] https://lore.kernel.org/linux-kselftest/20211005011340.2826268-1-dlatypov@google.com/ Signed-off-by: Daniel Latypov <dlatypov@google.com> Reviewed-by: David Gow <davidgow@google.com> Reviewed-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
