Continuing the consolidation on Python for various miscellaneous build
and test scripts, this patch moves conformtest from Perl to Python.
The substance of the tests run is intended to be the same as before,
except that the previous test for tags did not actually achieve the
intended purpose of verifying whether a tag was already declared, so
is changed to one that would actually fail for a tag that wasn't
declared, and a typo in the old test for variables being available
($xyzzy instead of xyzzy) would have made that test not use the
correct type (but it would have passed anyway with warnings). No
attempt is made to keep the details of what the test output looks
like; instead, tests are given names which are made to follow PASS: /
FAIL: / XFAIL: / SKIP: / MISSING: as appropriate.
In the new version, there is more consistent parsing of test lines
(into a series of words, either surrounded by {} or separated by
spaces) that applies for all kinds of test lines, rather than the old
approach of different regular expressions for every kind of test. A
few of the conform/data/ files are adjusted so their syntax works with
the new script (which now requires spaces in certain cases where the
old script tolerated them being missing, and does not allow stray
semicolons at the end of "function" lines). Similarly, common logic
is used around what happens with a second subtest if a first one fails
(e.g., a test for a symbol's type if the test for availability fails),
rather than such logic being replicated separately for each kind of
test. Common parsing also applies for test lines both when they are
lines for the header under test and when they are lines for another
header specified with allow-header, again unlike the old script.
Tested for x86_64, and with build-many-glibcs.py.
* conform/conformtest.py: New file.
* conform/conformtest.pl: Remove.
* conform/GlibcConform.pm: Likewise.
* conform/glibcconform.py (KEYWORDS_C90): New constant.
(KEYWORDS_C99): Likewise.
(KEYWORDS): Likewise.
* conform/Makefile ($(conformtest-header-tests)): Use
conformtest.py instead of conformtest.pl. Do not pass --tmpdir
option. Use --header instead of --headers.
* conform/data/arpa/inet.h-data: Remove trailing semicolons on
function entries.
* conform/data/spawn.h-data: Likewise.
* conform/data/fcntl.h-data (openat): Add space after function
name.
* conform/data/wchar.h-data (wcscasecmp): Likewise.
(wcscasecmp_l): Likewise.
* conform/data/termios.h-data (c_cc): Add space after element
name.
Now that we require Python 3.4 or later, Python code creating
temporary directories can use tempfile.TemporaryDirectory in "with" to
have the directory deleted automatically instead of needing to use
try/finally to handle removing a directory created with
tempfile.mkdtemp. This patch does so in conform/glibcconform.py.
Tested for x86_64.
* conform/glibcconform.py: Do not import shutil.
(list_exported_functions): Use tempfile.TemporaryDirectory instead
of mkdtemp.
Continuing the move of test code from Perl to Python (which seems
uncontroversial, unlike dependencies on Python in the actual build of
glibc), this patch replaces conform/list-header-symbols.pl with a
Python script, as a first step in converting the conform/ tests.
(conform/glibcconform.py is an equivalent to GlibcConform.pm,
containing code that will be relevant to move than one of the conform/
scripts.)
Tested for x86_64, including verifying that the symbol lists generated
are identical to those generated by the Perl version.
* conform/glibcconform.py: New file.
* conform/list-header-symbols.py: Likewise.
* conform/list-header-symbols.pl: Remove.
* conform/Makefile (tests-special): Only add linknamespace tests
if [PYTHON].
($(linknamespace-symlists-tests)): Use list-header-symbols.py.
