2022-07-06stdlib: Tests for mbrtoc8, c8rtomb, and the char8_t typedef.Tom Honermann
This change adds tests for the mbrtoc8 and c8rtomb functions adopted for C++20 via WG21 P0482R6 and for C2X via WG14 N2653, and for the char8_t typedef adopted for C2X from WG14 N2653. The tests for mbrtoc8 and c8rtomb specifically exercise conversion to and from Big5-HKSCS because of special cases that arise with that encoding. Big5-HKSCS defines some double byte sequences that convert to more than one Unicode code point. In order to test this, the locale dependencies for running tests under wcsmbs is expanded to include zh_HK.BIG5-HKSCS. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
2022-07-06stdlib: Implement mbrtoc8, c8rtomb, and the char8_t typedef.Tom Honermann
This change provides implementations for the mbrtoc8 and c8rtomb functions adopted for C++20 via WG21 P0482R6 and for C2X via WG14 N2653. It also provides the char8_t typedef from WG14 N2653. The mbrtoc8 and c8rtomb functions are declared in uchar.h in C2X mode or when the _GNU_SOURCE macro or C++20 __cpp_char8_t feature test macro is defined. The char8_t typedef is declared in uchar.h in C2X mode or when the _GNU_SOURCE macro is defined and the C++20 __cpp_char8_t feature test macro is not defined (if __cpp_char8_t is defined, then char8_t is a builtin type).

2021-11-10Support C2X printf %b, %BJoseph Myers
C2X adds a printf %b format (see <http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2630.pdf>, accepted for C2X), for outputting integers in binary. It also has recommended practice for a corresponding %B format (like %b, but %#B starts the output with 0B instead of 0b). Add support for these formats to glibc. One existing test uses %b as an example of an unknown format, to test how glibc printf handles unknown formats; change that to %v. Use of %b and %B as user-registered format specifiers continues to work (and we already have a test that covers that, tst-printfsz.c). Note that C2X also has scanf %b support, plus support for binary constants starting 0b in strtol (base 0 and 2) and scanf %i (strtol base 0 and scanf %i coming from a previous paper that added binary integer literals). I intend to implement those features in a separate patch or patches; as discussed in the thread starting at <https://sourceware.org/pipermail/libc-alpha/2020-December/120414.html>, they will be more complicated because they involve adding extra public symbols to ensure compatibility with existing code that might not expect 0b constants to be handled by strtol base 0 and 2 and scanf %i, whereas simply adding a new format specifier poses no such compatibility concerns. Note that the actual conversion from integer to string uses existing code in _itoa.c. That code has special cases for bases 8, 10 and 16, probably so that the compiler can optimize division by an integer constant in the code for those bases. If desired such special cases could easily be added for base 2 as well, but that would be an optimization, not actually needed for these printf formats to work. Tested for x86_64 and x86. Also tested with build-many-glibcs.py for aarch64-linux-gnu with GCC mainline to make sure that the test does indeed build with GCC 12 (where format checking warnings are enabled for most of the test).

2020-06-01mbstowcs: Document, test, and fix null pointer dst semantics (Bug 25219)Carlos O'Donell
The function mbstowcs, by an XSI extension to POSIX, accepts a null pointer for the destination wchar_t array. This API behaviour allows you to use the function to compute the length of the required wchar_t array i.e. does the conversion without storing it and returns the number of wide characters required. We remove the __write_only__ markup for the first argument because it is not true since the destination may be a null pointer, and so the length argument may not apply. We remove the markup otherwise the new test case cannot be compiled with -Werror=nonnull. We add a new test case for mbstowcs which exercises the destination is a null pointer behaviour which we have now explicitly documented. The mbsrtowcs and mbsnrtowcs behave similarly, and mbsrtowcs is documented as doing this in C11, even if the standard doesn't come out and call out this specific use case. We add one note to each of mbsrtowcs and mbsnrtowcs to call out that they support a null pointer for the destination. The wcsrtombs function behaves similarly but in the other way around and allows you to use a null destination pointer to compute how many bytes you would need to convert the wide character input. We document this particular case also, but leave wcsnrtombs as a references to wcsrtombs, so the reader must still read the details of the semantics for wcsrtombs.

2018-10-22Stop c32rtomb and mbrtoc32 aliasing wcrtomb and mbrtowc (bug 23793).Joseph Myers
glibc does: /* There should be no difference between the UTF-32 handling required by c32rtomb and the wchar_t handling which has long since been implemented in wcrtomb. */ weak_alias (__wcrtomb, c32rtomb) /* There should be no difference between the UTF-32 handling required by mbrtoc32 and the wchar_t handling which has long since been implemented in mbrtowc. */ weak_alias (__mbrtowc, mbrtoc32) The reasoning in those comments to justify those aliases is incorrect: ISO C requires that, for the case of a NULL mbstate_t* being passed, each function has its *own* internal static mbstate_t. Thus a program must be able to use both wcrtomb and c32rtomb at the same time with each keeping its own separate state, and likewise for mbrtowc and mbrtoc32. This patch duly sets up separarate char32_t function that wrap the wchar_t ones. Note that the included test only covers the mbrtoc32 / mbrtowc pair. While I think the change made is logically correct for c32rtomb / wcrtomb as well, I'm not sure we have a locale with a suitable state-dependent multibyte encoding for testing that part of the change.

2018-10-19Handle surrogate pairs in c16rtomb (bug 23794, DR#488, C2X).Joseph Myers
The c16rtomb implementation has: // XXX The ISO C 11 spec I have does not say anything about handling // XXX surrogates in this interface. The DR#488 resolution, as applied to C2X, requires surrogate pairs to be handled here (so the first call returns 0 and stores the high surrogate in the mbstate_t, while the second call combines the surrogates, produces a multibyte character and returns the number of bytes written). This patch implements that. (mbrtoc16 already handled producing surrogates as output.) Tested for x86_64.

2018-03-13[BZ 1190] Make EOF sticky in stdio.Zack Weinberg
C99 specifies that the EOF condition on a file is "sticky": once EOF has been encountered, all subsequent reads should continue to return EOF until the file is closed or something clears the "end-of-file indicator" (e.g. fseek, clearerr). This is arguably a change from C89, where the wording was ambiguous; the BSDs always had sticky EOF, but the System V lineage would attempt to read from the underlying fd again. GNU libc has followed System V for as long as we've been using libio, but nowadays C99 conformance and BSD compatibility are more important than System V compatibility. You might wonder if changing the _underflow impls is sufficient to apply the C99 semantics to all of the many stdio functions that perform input. It should be enough to cover all paths to _IO_SYSREAD, and the only other functions that call _IO_SYSREAD are the _seekoff impls, which is OK because seeking clears EOF, and the _xsgetn impls, which, as far as I can tell, are unused within glibc. The test programs in this patch use a pseudoterminal to set up the necessary conditions. To facilitate this I added a new test-support function that sets up a pair of pty file descriptors for you; it's almost the same as BSD openpty, the only differences are that it allocates the optionally-returned tty pathname with malloc, and that it crashes if anything goes wrong.

2018-02-07Define char16_t, char32_t consistently with uint_least16_t, uint_least32_t ↵Joseph Myers
(bug 17979). As noted in bug 17979 (and as I noted earlier in <https://sourceware.org/ml/libc-alpha/2012-02/msg00647.html>), uchar.h has gratuitously complicated code to determine the types for char16_t and char32_t, and to reject including that header for pre-C11 compilers not defining __CHAR16_TYPE__ and __CHAR32_TYPE__. Since those types are always required to match uint_least16_t and uint_least32_t, which glibc knows how to define without reference to such predefined macros, it's safe just to define those types the same as the *least* types are defined in stdint.h, so allowing the header to work with (for example) GCC 4.3. This patch implements that. bits/types.h is made to define __int_leastN_t and __uint_leastN_t so the logic for those types can stay in a single place, and stdint.h is made to use those __*_t to define the public *_t types. uchar.h is then made to use __uint_least16_t and __uint_least32_t to define char16_t and char32_t, so simplifying the logic there. A new test is added that verifies the types chosen for char16_t and char32_t do indeed match the types the compiler uses for u"" and U"" string literals. Tested for x86_64. (I have not tested with any of the older compilers for which this would actually make a difference to whether you can include uchar.h.) [BZ #17979] * posix/bits/types.h (__int_least8_t): New typedef.

2015-11-24Refactor strtod parsing of NaN payloads.Joseph Myers
The nan* functions handle their string argument by constructing a NAN(...) string on the stack as a VLA and passing it to strtod functions. This approach has problems discussed in bug 16961 and bug 16962: the stack usage is unbounded, and it gives incorrect results in certain cases where the argument is not a valid n-char-sequence. The natural fix for both issues is to refactor the NaN payload parsing out of strtod into a separate function that the nan* functions can call directly, so that no temporary string needs constructing on the stack at all. This patch does that refactoring in preparation for fixing those bugs (but without actually using the new functions from nan* - which will also require exporting them from libc at version GLIBC_PRIVATE). This patch is not intended to change any user-visible behavior, so no tests are added (fixes for the above bugs will of course add tests for them). This patch builds on my recent fixes for strtol and strtod issues in Turkish locales. Given those fixes, the parsing of NaN payloads is locale-independent; thus, the new functions do not need to take a locale_t argument.

2015-11-24Fix strtod ("NAN(I)") in Turkish locales (bug 19266).Joseph Myers
The implementations of strtod and related functions use locale-specific conversions to lower case when parsing the contents of a string NAN(n-char-sequence_opt). This has the consequence that NAN(I) is not treated as being of that form (only the initial NAN part is accepted). The syntax of n-char-sequence directly maps to the ASCII letters, digits and underscore as in identifiers, so it is unambiguous that all ASCII letters must be accepted in all locales. This patch, relative to a tree with <https://sourceware.org/ml/libc-alpha/2015-11/msg00258.html> (pending review) applied and depending on that patch, fixes this problem by checking directly for ASCII letters. This will have the side effect of no longer accepting 'İ' (dotted 'I') inside NAN() in Turkish locales, which seems appropriate (that letter wouldn't have been interpreted as having any meaning in the NaN payload anyway, as not acceptable to strtoull). Tested for x86_64 and x86.

2015-11-23Fix strtol in Turkish locales (bug 19242).Joseph Myers
The implementations of strtol and related functions use locale-specific conversions to upper case before determining whether a character is a valid letter in the argument. This means that in Turkish locales such as tr_TR.UTF-8 and tr_TR.ISO-8859-9, "i" is interpreted as not being a valid number, when if the base passed to strtol is 19 or more it should be interpreted as the number 18. ISO C explicitly says "The letters from a (or A) through z (or Z) are ascribed the values 10 through 35", so clearly intends the standard ASCII letters (otherwise you wouldn't generally have exactly 26 letters to ascribe such values) (whereas white-space must be identified according to the locale). In particular, 'i' and 'I' must be understood to be in that sequence. This patch makes the code do the case conversions and classification in the C locale; the user's locale remains used for whitespace testing (explicitly correct according to ISO C). Note that the way the code worked, the only non-ASCII letter that would previously have been accepted would have been the Turkish 'ı' (dotless 'i'), because the uppercase version of that in Turkish locales is 'I'. This patch means that will no longer be accepted, which seems appropriate. Tested for x86_64 and x86. [BZ #19242] * stdlib/strtol_l.c (ISALPHA): Use _nl_C_locobj_ptr for locale.

2014-11-26Remove TEST_IFUNC, tests-ifunc and *-ifunc.c tests.Joseph Myers
TEST_IFUNC is only tested in two headers, bench-string.h and test-string.h, after it gets defined by those headers, and it never gets undefined. Thus no defines of TEST_IFUNC are needed, and the *-ifunc.c tests that just define TEST_IFUNC and include other tests are also redundant, as is the code to remove $(tests-ifunc) and $(xtests-ifunc) conditionally from tests and xtests. This patch removes the useless defines and tests of TEST_IFUNC and the associated useless tests and makefile code. It thereby fixes a series of warnings "../string/test-string.h:21:0: warning: "TEST_IFUNC" redefined" where test-string.h defines TEST_IFUNC to empty, other files define it to 1 and this produces warnings. Tested for x86_64. * debug/test-stpcpy_chk-ifunc.c: Remove file. * debug/test-strcpy_chk-ifunc.c: Likewise. * wcsmbs/test-wcschr-ifunc.c: Likewise. * wcsmbs/test-wcscmp-ifunc.c: Likewise. * wcsmbs/test-wcscpy-ifunc.c: Likewise. * wcsmbs/test-wcslen-ifunc.c: Likewise. * wcsmbs/test-wcsrchr-ifunc.c: Likewise. * wcsmbs/test-wmemcmp-ifunc.c: Likewise. * Rules [$(multi-arch) = no] (tests): Do not filter out $(tests-ifunc).

2014-06-04Include LOCPATH in default test environment.Joseph Myers
Tests run using the default $(make-test-out) automatically get GCONV_PATH and LC_ALL set, whether or not those environment variables are actually needed for the individual test. However, they do not get LOCPATH set, meaning that a large number of tests have -ENV settings just to set LOCPATH. This patch moves LOCPATH into the default environment used for all tests, on the principle that like GCONV_PATH any settings needed to use files associated with the newly built library, rather than any old installed files, are appropriate to use by default. A further motivation is that various tests using .sh files also set some combination of LC_ALL, GCONV_PATH and LOCPATH. Preferably .sh files should also use the default environment with any additions required for the individual test. Now, it was suggested in <https://sourceware.org/ml/libc-alpha/2014-05/msg00715.html> that various Makefile variables used in testing should be derived by composing the -before-env and -after-env variables used when explicit environment settings are required. With such a change, it's also natural for those variables to include the default settings (via some intermediate makefile variable also used in make-test-out). Because some .sh files only set variables that correspond to the default settings, or a subset thereof, and this applies to more of the .sh files once LOCPATH is in the default settings, doing so reduces the size of a revised version of <https://sourceware.org/ml/libc-alpha/2014-05/msg00596.html>: scripts only needing the (expanded) default settings will not need to receive the separate -before-env and -after-env variables, only the single variable they do at present. So moving LOCPATH into the default settings can reduce churn caused by subsequent patches.

2014-02-26Consistently include Makeconfig after defining subdir.Joseph Myers
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I noted it was necessary to add includes of Makeconfig early in various subdirectory makefiles for the tests-special variable settings added by that patch to be conditional on configuration information. No-one commented on the general question there of whether Makeconfig should always be included immediately after the definition of subdir. This patch implements that early inclusion of Makeconfig in each directory (which is a lot easier than consistent placement of includes of Rules). Includes are added if needed, or moved up if already present. Subdirectory "all:" targets are removed, since Makeconfig provides one. There is potential for further cleanups I haven't done. Rules and Makerules have code such as ifneq "$(findstring env,$(origin headers))" "" headers := endif to override to empty any value of various variables that came from the environment. I think there is a case for Makeconfig setting all the subdirectory variables (other than subdir) to empty to ensure no outside value is going to take effect if a subdirectory fails to define a variable. (A list of such variables, possibly out of date and incomplete, is in manual/maint.texi.) Rules and Makerules would give errors if Makeconfig hadn't already been included, instead of including it themselves. The special code to override values coming from the environment would then be obsolete and could be removed.
