2018-12-18locale: Rewrite locale/gen-translit.pl in PythonFlorian Weimer
This commit does not change the generated output file. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2018-12-17Add test that MAP_* constants agree with kernel.Joseph Myers
Continuing the process of building up and using Python infrastructure for extracting and using values in headers, this patch adds a test that MAP_* constants from sys/mman.h agree with those in the Linux kernel headers. (Other sys/mman.h constants could be added to the test separately.) This set of constants has grown over time, so the generic code is enhanced to allow saying extra constants are OK on either side of the comparison (where the caller sets those parameters based on the Linux kernel headers version, compared with the version the headers were last updated from). Although the test is a custom Python file, my intention is to move in future to a single Python script for such tests and text files it takes as inputs, once there are enough examples to provide a guide to the common cases in such tests (I'd like to end up with most or all such sets of constants copied from kernel headers having such tests, and likewise for structure layouts from the kernel). The Makefile code is essentially the same as for tst-signal-numbers, but I didn't try to find an object file to depend on to represent the dependency on the headers used by the test (the conform/ tests don't try to represent such header dependencies at all, for example). Tested with build-many-glibcs.py, and also for x86_64 with older kernel headers. * scripts/glibcextract.py (compare_macro_consts): Take parameters to allow extra macros from first or second sources. * sysdeps/unix/sysv/linux/tst-mman-consts.py: New file. * sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc] (tests-special): Add $(objpfx)tst-mman-consts.out.

2018-12-10Use gen-as-const.py to process .pysym files.Joseph Myers
This patch eliminates the gen-py-const.awk variant of gen-as-const, switching to use of gnu-as-const.py (with a new --python option) to process .pysym files (i.e., to generate nptl_lock_constants.py), as the syntax of those files is identical to that of .sym files. Note that the generated nptl_lock_constants.py is *not* identical to the version generated by the awk script. Apart from the trivial changes (comment referencing the new script, and output being sorted), the constant FUTEX_WAITERS, PTHREAD_MUTEXATTR_FLAG_BITS, PTHREAD_MUTEXATTR_FLAG_PSHARED and PTHREAD_MUTEX_PRIO_CEILING_MASK are now output as positive rather than negative constants (on x86_64 anyway; maybe not necessarily on 32-bit systems): < FUTEX_WAITERS = -2147483648 --- > FUTEX_WAITERS = 2147483648 < PTHREAD_MUTEXATTR_FLAG_BITS = -251662336 < PTHREAD_MUTEXATTR_FLAG_PSHARED = -2147483648 --- > PTHREAD_MUTEXATTR_FLAG_BITS = 4043304960 > PTHREAD_MUTEXATTR_FLAG_PSHARED = 2147483648 < PTHREAD_MUTEX_PRIO_CEILING_MASK = -524288 --- > PTHREAD_MUTEX_PRIO_CEILING_MASK = 4294443008 This is because gen-as-const has a cast of the constant value to long int, which gen-py-const lacks. I think the positive values are more logically correct, since the constants in question are in fact unsigned in C. But to reliably produce gen-as-const.py output for constants that always (in C and Python) reflects the signedness of values with the high bit of "long int" set would mean more complicated logic needs to be used in computing values. The more correct positive values by themselves produce a failure of nptl/test-mutexattr-printers, because masking with ~PTHREAD_MUTEXATTR_FLAG_BITS & ~PTHREAD_MUTEX_NO_ELISION_NP now leaves a bit -1 << 32 in the Python value, resulting in a KeyError exception. To avoid that, places masking with ~ of one of the constants in question are changed to mask with 0xffffffff as well (this reflects how ~ in Python applies to an infinite-precision integer whereas ~ in C does not do any promotions beyond the width of int). Tested for x86_64. * scripts/gen-as-const.py (main): Handle --python option. * scripts/gen-py-const.awk: Remove. * Makerules (py-const-script): Use gen-as-const.py. ($(py-const)): Likewise. * nptl/nptl-printers.py (MutexPrinter.read_status_no_robust): Mask with 0xffffffff together with ~(PTHREAD_MUTEX_PRIO_CEILING_MASK).

2018-12-10Move tst-signal-numbers to Python.Joseph Myers
This patch converts the tst-signal-numbers test from shell + awk to Python. As with gen-as-const, the point is not so much that shell and awk are problematic for this code, as that it's useful to build up general infrastructure in Python for use of a range of code involving extracting values from C headers. This patch moves some code from gen-as-const.py to a new glibcextract.py, which also gains functions relating to listing macros, and comparing the values of a set of macros from compiling two different pieces of code. It's not just signal numbers that should have such tests; pretty much any case where glibc copies constants from Linux kernel headers should have such tests that the values and sets of constants agree except where differences are known to be OK. Much the same also applies to structure layouts (although testing those without hardcoding lists of fields to test will be more complicated). Given this patch, another test for a set of macros would essentially be just a call to glibcextract.compare_macro_consts (plus boilerplate code - and we could move to having separate text files defining such tests, like the .sym inputs to gen-as-const, so that only a single Python script is needed for most such tests). Some such tests would of course need new features, e.g. where the set of macros changes in new kernel versions (so you need to allow new macro names on the kernel side if the kernel headers are newer than the version known to glibc, and extra macros on the glibc side if the kernel headers are older). tst-syscall-list.sh could become a Python script that uses common code to generate lists of macros but does other things with its own custom logic. There are a few differences from the existing shell + awk test. Because the new test evaluates constants using the compiler, no special handling is needed any more for one signal name being defined to another. Because asm/signal.h now needs to pass through the compiler, not just the preprocessor, stddef.h is included as well (given the asm/signal.h issue that it requires an externally provided definition of size_t). The previous code defined __ASSEMBLER__ with asm/signal.h; this is removed (__ASSEMBLY__, a different macro, eliminates the requirement for stddef.h on some but not all architectures). Tested for x86_64, and with build-many-glibcs.py. * scripts/glibcextract.py: New file. * scripts/gen-as-const.py: Do not import os.path, re, subprocess or tempfile. Import glibcexctract. (compute_c_consts): Remove. Moved to glibcextract.py. (gen_test): Update reference to compute_c_consts.

2018-12-03Make gen-as-const.py handle '--' consistently with awk script.Joseph Myers
It was reported in <https://sourceware.org/ml/libc-alpha/2018-12/msg00045.html> that gen-as-const.py fails to generate test code in the case where a .sym file has no symbols in it, so resulting in a test failing to link for Hurd. The relevant difference from the old awk script is that the old script treated '--' lines as indicating that the text to do at the start of the test (or file used to compute constants) should be output at that point if not already output, as well as treating lines with actual entries for constants like that. This patch changes gen-as-const.py accordingly, making it the sole responsibility of the code parsing .sym files to determine when such text should be output and ensuring it's always output at some point even if there are no symbols and no '--' lines, since not outputting it means the test fails to link. Handling '--' like that also avoids any problems that would arise if the first entry for a symbol were inside #ifdef (since the text in question must not be output inside #ifdef). Tested for x86_64, and with build-many-glibcs.py for i686-gnu. Note that there are still compilation test failures for i686-gnu (linknamespace tests, possibly arising from recent posix_spawn-related changes). * scripts/gen-as-const.py (compute_c_consts): Take an argument 'START' to indicate that start text should be output. (gen_test): Likewise. (main): Generate 'START' for first symbol or '--' line, or at end of input if not previously generated.
2018-12-03Fix test-as-const-jmp_buf-ssp.c generation on gnu-i386Samuel Thibault
hurd's jmp_buf-ssp.sym does not define any symbol. scripts/gen-as-const.py currently was emitting an empty line in that case, and the gawk invocation was prepending "asconst_" to it, ending up with: .../build/glibc/setjmp/test-as-const-jmp_buf-ssp.c:1:2: error: expected « = », « , », « ; », « asm » or « __attribute__ » at end of input 1 | asconst_ | ^~~~~~~~ * scripts/gen-as-const.py (main): Avoid emitting empty line when there is no element in `consts'.

2018-11-30Replace gen-as-const.awk by gen-as-const.py.Joseph Myers
This patch replaces gen-as-const.awk, and some fragments of the Makefile code that used it, by a Python script. The point is not such much that awk is problematic for this particular script, as that I'd like to build up a general Python infrastructure for extracting information from C headers, for use in writing tests of such headers. Thus, although this patch does not set up such infrastructure, the compute_c_consts function in gen-as-const.py might be moved to a separate Python module in a subsequent patch as a starting point for such infrastructure. The general idea of the code is the same as in the awk version, but no attempt is made to make the output files textually identical. When generating a header, a dict of constant names and values is generated internally then defines are printed in sorted order (rather than the order in the .sym file, which would have been used before). When generating a test that the values computed match those from a normal header inclusion, the test code is made into a compilation test using _Static_assert, where previously the comparisons were done only when the test was executed. One fragment of test generation (converting the previously generated header to use asconst_* prefixes on its macro names) is still in awk code in the makefiles; only the .sym processing and subsequent execution of the compiler to extract constants have moved to the Python script. Tested for x86_64, and with build-many-glibcs.py. * scripts/gen-as-const.py: New file. * scripts/gen-as-const.awk: Remove. * Makerules ($(common-objpfx)%.h $(common-objpfx)%.h.d): Use gen-as-const.py. ($(objpfx)test-as-const-%.c): Likewise.
2018-11-29posix: Do not include testcases.h, ptestcases.h in source treeFlorian Weimer
These files were both auto-generated and shipped in the source tree. We can assume that sed is available and always generate the files during the build.
2018-11-28Do not copy glibc sources in build-many-glibcs.py.Joseph Myers
Now that build-many-glibcs.py touches at checkout time all files that might get rebuilt in the glibc source directory in a normal glibc build and test run, this patch stops the script from copying the glibc source directory, so that all builds use the original directory directly (and less disk space is used, less I/O is involved and cached copies of the sources in memory can be shared between all the builds - as well as avoiding spurious failures from copying while "git gc" is running). This is similar to how all other components were already handled. Any bugs involving writing into the source directory can be dealt with in future as normal bugs, just as such bugs already are handled. Tested with build-many-glibcs.py runs with a read-only glibc source directory, with all files not touched by the script having timestamps in forwards alphabetical order and separately with all files not touched by the script having timestamps in backwards alphabetical order. * scripts/build-many-glibcs.py (Glibc.build_glibc): Use original source directory instead of a copy. (CommandList.create_copy_dir): Remove.
2018-11-26abilist.awk: Treat .tdata like .tbss and reject unknown combinations.Carlos O'Donell
Mathieu Desnoyers ran into an issue with his rseq patch where he was the first person to add weak thread-local data and this resulted in an ABI list update with entries like this: "GLIBC_2.29 w ? D .tdata 0000000000000020". The weakness of the symbol has nothing to do with the DSOs ABI and so we should not write anything about weak symbols here. The .tdata entries should be treated exactly like .tbss entries and the output should have been: "GLIBC_2.29 __rseq_abi T 0x20" This change makes abilist.awk handle .tdata just like .tbss, while at the same time adding an error case for the default, and the unknown line cases. We never want anyone to be able to add such entries to any ABI list files and should see an immediate error and consult with experts. Tested by Mathieu Desnoyers <mathieu.desnoyers@efficios.com> with the rseq patch set and 'make update-all-abi'. Tested myself with 'make update-all-abi' on x86_64 with no changes.

2018-11-26Touch more glibc source files in build-many-glibcs.py.Joseph Myers
build-many-glibcs.py currently copies the source tree to avoid issues with parallel builds trying to write into it. This copying can result in occasional spurious build failures from bots, when a "git gc" is in progress that changes .git contents while copying is taking place, and it would also be desirable to avoid the need to copy to save on disk space, I/O and memory used in build-many-glibcs.py builds. In preparation for removing the copying, this patch arranges for build-many-glibcs.py to touch more files on checkout so their timestamps do not result in make attempting to rebuild them. Before actually removing the copying, I intend to do further tests to ensure I haven't missed any other such makefile dependencies. This is of course without prejudice to possibly moving more of these files to being generated in the build directory rather than being checked in at all, where that can be done using build tools already required for the build. For sysdeps files (installed and otherwise) it would be necessary to make sure this does not affect the search ordering, for headers used in the build it would be necessary to ensure they are generated early enough, and for errlist.c there may be dual licensing reasons for keeping it checked in. Tested that a checkout with build-many-glibcs.py does touch the expected files and that a glibcs build for aarch64-linux-gnu succeeds. * scripts/build-many-glibcs.py (Context.fix_glibc_timestamps): Touch additional files.

2018-10-26Remove pre-Python-3.4 compatibility from build-many-glibcs.py.Joseph Myers
Since we have consensus on requiring Python 3.4 or later to build glibc, it follows that compatibility with older Python versions is also no longer relevant to auxiliary Python scripts for use in glibc development. This patch removes such compatibility code from build-many-glibcs.py (compatibility code needed for 3.4, which lacks the newer subprocess interface, is kept). Because build-many-glibcs.py is not itself called from the glibc build system, this patch is independent of the configure checks for having a new-enough Python version, which are only relevant to uses of Python from the main build and test process. Tested with build-many-glibcs.py building glibc for aarch64-linux-gnu (with Python 3.4 to make sure that still works). * scripts/build-many-glibcs.py: Remove compatibility for missing os.cpu_count and re.fullmatch.
2018-10-22Use Linux 4.19 in build-many-glibcs.py.Joseph Myers
* scripts/build-many-glibcs.py (Context.checkout): Default Linux version to 4.19.
2018-09-24Don't build libnsl for new ABIsAndreas Schwab
For architectures and ABIs that are added in version 2.29 or later the option --enable-obsolete-nsl is no longer available, and no libnsl compatibility library is built.
2018-09-11Add build-many-glibcs.py support for building more GCC libraries.Joseph Myers
Every so often we get libsanitizer or libgo builds breaking with new glibc because of some change in the glibc headers. glibc's build-many-glibcs.py deliberately disables libsanitizer and GCC languages other than C and C++ because the point is to test glibc and find glibc problems (including problems shown up by new compiler warnings in new GCC), not to test libsanitizer or libgo; if the compiler build fails because of libsanitizer or libgo failing to build, that could hide the existence of new problems in glibc. However, it seems reasonable to have a non-default mode where build-many-glibcs.py does build those additional pieces, which this patch adds. Note that I do not intend to run a build-many-glibcs.py bot with this new option. If people concerned with libsanitizer, libgo or other potentially affected GCC libraries wish to find out about such problems more quickly, they may wish to run such a bot or bots (and to monitor the results and fix issues found - obviously there will be some overlap with issues found by my bots not using that option). Note also that building a non-native Ada compiler requires a sufficiently recent native (or build-x-host, in general) Ada compiler to be used, possibly more or less the same version as being built. That needs to be in the PATH when build-many-glibcs.py --full-gcc is run; the script does not deal with setting up such a compiler (or any of the other host tools needed for building GCC and glibc, beyond the GMP / MPFR / MPC libraries), but perhaps it should, to avoid the need to keep updating such a compiler manually when running a bot. Tested by running build-many-glibcs.py with the new option, with mainline GCC. There are build failures for various configurations, which may be of interest to Go / Ada people even if you're not interested in running such a bot: * mips64 / mips64el (all configuration): ICE building libstdc++, as seen without using the new option <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87156>. * aarch64_be: error building libgo (little-endian aarch64 works fine): version.go:67:13: error: expected ';' or ')' or newline 67 | BigEndian = | ^ version.go:67:3: error: reference to undefined name 'BigEndian' 67 | BigEndian = | ^ * arm (all configurations): error building libgo: /scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:29:5: error: reference to undefined name 'randomTrap' 29 | if randomTrap == 0 { | ^ /scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:38:34: error: reference to undefined name 'randomTrap' 38 | r1, _, errno := syscall.Syscall(randomTrap, | ^ What's happening there is, I think, that the arm*b*-*-* case in libgo/configure.ac is wrongly matching arm-glibc-linux-gnueabi with the 'b' in the vendor part, and then something else is failing to handle GOARCH=armbe. Given that you can have configurations with multilibs of both endiannesses, endianness should always be detected by configure.ac, for all architectures, using a compile test of whether __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, not based on textual matches to the host (= target at top-level) triplet. * armeb (all configurations): error building libada (for some reason the Arm libada configuration seems to do different things for EH for big-endian, which makes no sense to me and doesn't actually work): a-exexpr.adb:87:06: "System.Exceptions.Machine" is not a predefined library unit a-exexpr.adb:87:06: "Ada.Exceptions (body)" depends on "Ada.Exceptions.Exception_Propagation (body)" a-exexpr.adb:87:06: "Ada.Exceptions.Exception_Propagation (body)" depends on "System.Exceptions.Machine (spec)" * hppa: error building libgo (same error as for aarch64_be). * ia64: ICE building libgo.

2018-09-10Add build-many-glibcs.py --enable-obsolete-* configs.Joseph Myers
We've had issues before with build failures (with new GCC) in code only built with --enable-obsolete-rpc or --enable-obsolete-nsl not being reported for a while because build-many-glibcs.py does not test those configure options. This patch adds configurations (32-bit and 64-bit) using those options so that in future we can notice quickly if they start failing to build. Tested the new configurations do build with GCC 8. * scripts/build-many-glibcs.py (Context.add_all_configs): Add x86_64 and i686 configs using --enable-obsolete-rpc --enable-obsolete-nsl.

2018-06-26Fix hardcoded /tmp paths in testing (bug 13888).Joseph Myers
As noted in bug 13888, and as I noted previously in <https://sourceware.org/ml/libc-alpha/2000-10/msg00111.html>, various tests used hardcoded paths in /tmp, so posing issues for simultaneous test runs from different build directories. This patch fixes such uses of hardcoded file names to put them in the build directory instead (in the case of stdio-common/bug5 the file names are changed as well, to avoid a conflict with the name bug5.out also used for the automatic test output redirection). It also fixes test-installation.pl likewise (that was using filenames with $$ in them rather than strictly hardcoded names, but that's still not good practice for temporary file naming). Note that my list of files changed is not identical to that in bug 13888. I added tst-spawn3.c and test-installation.pl, and removed some tests that seem to me (now) to create temporary files securely (simply using /tmp is not itself a problem if the temporary files are handled properly with mkstemp; I haven't checked whether those tests used to do things insecurely). conformtest is not changed because the makefiles always pass a --tmpdir option so the /tmp default is irrelevant, and for the same reason there is no actual problem with nptl/tst-umask1.c because again the makefiles always override the default. nptl/sockperf.c is ignored because there is no code to run it; probably that file should actually be removed. Some tests use the mktemp function, but I think they all use it in a way that *is* secure (for generating names for directories / sockets / fifos / symlinks, where the operation using the name will not follow symlinks and so there is no potential for a symlink attack on the account running the testsuite). Some tests use the tmpnam function to generate temporary file names. This is in principle insecure, but not addressed by this patch (I consider it a separate issue from the fully hardcoded paths). Tested for x86_64.

_init and _fini are special functions provided by glibc for linker to define DT_INIT and DT_FINI in executable and shared library. They should never be put in dynamic symbol table.

2018-05-04Ignore absolute symbols in ABI tests.Joseph Myers
A recent binutils patch <https://sourceware.org/ml/binutils/2018-04/msg00336.html> stops the MIPS linker including the _gp_disp absolute symbol in dynamic symbol tables. With older binutils, it is included for MIPS o32 (despite the use of symbol versioning), and this means that all the ABI test baselines for MIPS o32 include "_gp_disp _gp_disp A". This symbol is not meaningfully part of the ABI for shared libraries, since it always has to be resolved at static link time to the local definition for the linked object. All the other absolute symbols in ABI test baselines are the names of symbol versions. I don't think the mere existence of a symbol version with a given name - as opposed to the contents of that version if nonempty - is part of the ABI either. Thus, this patch allows the ABI tests to pass both before and after the binutils change by changing abilist.awk not to include absolute symbols in its output, and changing the baselines accordingly. Tested for x86_64, and with build-many-glibcs.py. * scripts/abilist.awk: Ignore absolute symbols. * sysdeps/mach/hurd/i386/ld.abilist: Remove absolute symbols. *

2018-04-27Remove tilegx port.Joseph Myers
Since tile support has been removed from the Linux kernel for 4.17, this patch removes the (unmaintained) port to tilegx from glibc (the tilepro support having been previously removed). This reflects the general principle that a glibc port needs upstream support for the architecture in all the components it build-depends on (so binutils, GCC and the Linux kernel, for the normal case of a port supporting the Linux kernel but no other OS), in order to be maintainable. Apart from removal of sysdeps/tile and sysdeps/unix/sysv/linux/tile, there are updates to various comments referencing tile for which removal of those references seemed appropriate. The configuration is removed from README and from build-many-glibcs.py. contrib.texi keeps mention of removed contributions, but I updated Chris Metcalf's entry to reflect that he also contributed the non-removed support for the generic Linux kernel syscall interface. __ASSUME_FADVISE64_64_NO_ALIGN support is removed, as it was only used by tile. * sysdeps/tile: Remove. * sysdeps/unix/sysv/linux/tile: Likewise. * README (tilegx-*-linux-gnu): Remove from list of supported configurations. * manual/contrib.texi (Contributors): Mention Chris Metcalf's contribution of support for generic Linux kernel syscall interface. * scripts/build-many-glibcs.py (Context.add_all_configs): Remove tilegx configurations. (Config.install_linux_headers): Do not handle tile. * sysdeps/unix/sysv/linux/aarch64/ldsodefs.h: Do not mention Tile in comment. * sysdeps/unix/sysv/linux/nios2/Makefile: Likewise. * sysdeps/unix/sysv/linux/posix_fadvise.c: Likewise. [__ASSUME_FADVISE64_64_NO_ALIGN] (__ALIGNMENT_ARG): Remove conditional undefine and redefine. * sysdeps/unix/sysv/linux/posix_fadvise64.c: Do not mention Tile in comment. [__ASSUME_FADVISE64_64_NO_ALIGN] (__ALIGNMENT_ARG): Remove conditional undefine and redefine.
2018-04-25Use GCC 8 in build-many-glibcs.py by default.Joseph Myers
Now that GCC 8 has branched, this patch makes build-many-glibcs.py default to using GCC 8 branch instead of GCC 7. The effect should be that all builds complete cleanly and the compilation parts of the glibc testsuite complete cleanly except for on i686-gnu (with GCC 7 there were testsuite failures for some other configurations as well). I've replaced my bot building using GCC 6 branch with one using GCC 8 branch. (Of course glibc should continue building with GCC 6 - and for that matter GCC 5 and 4.9, which are no longer maintained, are supported versions as well - but building with GCC 6 will no longer be included in my bot testing.) * scripts/build-many-glibcs.py (Context.checkout): Default GCC version to GCC 8 branch.
2018-04-19Disable lock elision for mutex pretty printer tests.Stefan Liebler
If e.g. the testcase nptl/test-mutex-printers is run with enabled lock-elision, it fails on s390x with: Error: Response does not match the expected pattern. Command: print *mutex Expected pattern: pthread_mutex_t Response: No symbol "mutex" in current context. (gdb) See https://www.sourceware.org/ml/libc-alpha/2018-03/msg00583.html for more details. In fact the mutex pretty printer tests rely on looking at the internal details of the lock, thus we disable it by setting up the GLIB_TUNABLES environment variable inside gdb. ChangeLog: * scripts/test_printers_common.py (init_test): Disable lock elision.
2018-04-18Make build-many-glibcs.py build GCC for powerpcspe with --enable-obsolete.Joseph Myers
The powerpcspe GCC port has been obsoleted in GCC 8 for not having had the removal of code for non-SPE processors completed. This patch accordingly arranges for build-many-glibcs.py to configure GCC with --enable-obsolete for affected configurations. This is temporary; either the port gets cleaned up and unobsoleted in GCC and the configure option can be removed, or the port gets removed in GCC and we should remove the corresponding glibc support. Tested with build-many-glibcs.py for the affected configurations. * scripts/build-many-glibcs.py (Context.add_all_configs): Use --enable-obsolete for powerpc-linux-gnuspe.

2018-02-07Don't install libio.h or _G_config.h.Zack Weinberg
We shipped 2.27 with libio.h and _G_config.h still installed but issuing warnings when used. Let's stop installing them early in 2.28 so that we have plenty of time to think of another plan if there are problems. The public stdio.h had a genuine dependency on libio.h for the complete definitions of FILE and cookie_io_functions_t, and a genuine dependency on _G_config.h for the complete definitions of fpos_t and fpos64_t; these are moved to single-type headers. bits/types/struct_FILE.h also provides a handful of accessor and bitflags macros so that code is not duplicated between bits/stdio.h and libio.h. All the other _IO_ and _G_ names used by the public stdio.h can be replaced with either public names or __-names. In order to minimize the risk of breaking our own compatibility code, bits/types/struct_FILE.h preserves the _IO_USE_OLD_IO_FILE mechanism exactly as it was in libio.h, but you have to define _LIBC to use it, or it'll error out. Similarly, _IO_lock_t_defined is preserved exactly, but will error out if used without defining _LIBC. Internally, include/stdio.h continues to include libio.h, and libio.h scrupulously provides every _IO_* and _G_* name that it always did, perhaps now defined in terms of the public names. This is how this patch avoids touching dozens of files throughout glibc and becoming entangled with the _IO_MTSAFE_IO mess. The remaining patches in this series eliminate most of the _G_ names. Tested on x86_64-linux; in addition to the test suite, I installed the library in a sysroot and verified that a simple program that uses stdio.h could be compiled against the installed library, and I also verified that installed stripped libraries are unchanged. * libio/bits/types/__fpos_t.h, libio/bits/types/__fpos64_t.h: New single-type headers split from _G_config.h. * libio/bits/types/cookie_io_functions_t.h * libio/bits/types/struct_FILE.h New single-type headers split from libio.h. * libio/Makefile: Install the above new headers. Don't install libio.h, _G_config.h, bits/libio.h, bits/_G_config.h, or bits/libio-ldbl.h. * libio/_G_config.h, libio/libio.h: Delete file. * libio/bits/libio.h: Remove improper-inclusion guard. Include stdio.h and don't repeat anything that it does. Define _IO_fpos_t as __fpos_t, _IO_fpos64_t as __fpos64_t, _IO_BUFSIZ as BUFSIZ, _IO_va_list as __gnuc_va_list, __io_read_fn as cookie_read_function_t, __io_write_fn as cookie_write_function_t, __io_seek_fn as cookie_seek_function_t, __io_close_fn as cookie_close_function_t, and _IO_cookie_io_functions_t as cookie_io_functions_t. Define _STDIO_USES_IOSTREAM, __HAVE_COLUMN, and _IO_file_flags here, in the "compatibility defines" section. Remove an #if 0 block. Use the "body" macros from bits/types/struct_FILE.h to define _IO_getc_unlocked, _IO_putc_unlocked, _IO_feof_unlocked, and _IO_ferror_unlocked. Move prototypes of __uflow and __overflow... * libio/stdio.h: ...here. Don't include bits/libio.h. Don't define _STDIO_USES_IOSTREAM. Get __gnuc_va_list directly from stdarg.h. Include bits/types/__fpos_t.h, bits/types/__fpos64_t.h, bits/types/struct_FILE.h, and, when __USE_GNU, bits/types/cookie_io_functions_t.h. Use __gnuc_va_list, not _G_va_list; __fpos_t, not _G_fpos_t; __fpos64_t, not _G_fpos64_t; FILE, not struct _IO_FILE; cookie_io_functions_t, not _IO_cookie_io_functions_t; __ssize_t, not _IO_ssize_t. Unconditionally define BUFSIZ as 8192 and EOF as (-1). * libio/bits/stdio.h: Add multiple-include guard. Use the "body" macros from bits/types/struct_FILE.h instead of _IO_* macros from libio.h; use __gnuc_va_list instead of va_list and __ssize_t instead of _IO_ssize_t. * libio/bits/stdio2.h: Similarly. * libio/iolibio.h: Add multiple-include guard. Include bits/libio.h after stdio.h. * libio/libioP.h: Add multiple-include guard. Include stdio.h and bits/libio.h before iolibio.h. * include/bits/types/__fpos_t.h, include/bits/types/__fpos64_t.h * include/bits/types/cookie_io_functions_t.h * include/bits/types/struct_FILE.h: New wrappers. * bits/_G_config.h, sysdeps/unix/sysv/linux/_G_config.h: Get definitions of _G_fpos_t and _G_fpos64_t from bits/types/__fpos_t.h and bits/types/__fpos64_t.h respectively. Remove improper-inclusion guards. * conform/data/stdio.h-data: Update expectations of va_list. * scripts/check-installed-headers.sh: Remove special case for libio.h and _G_config.h.

2018-01-29Make build-many-glibcs.py clean git source directories.Joseph Myers
With the git checkouts of Hurd components in build-many-glibcs.py involving running autoreconf, there's a risk that generated files could be left behind by an old autoreconf run (if an old version of the sources generates those files in the source directory but a new version does not). This patch avoids that by using git clean -dxfq when updating git checkouts. In this patch, that's conditional on --replace-sources, to avoid removing any local not-checked-in files someone may have in their checkout unless the option has been specifically passed that says it's OK to blow old checkouts away, complete with any local changes to them. * scripts/build-many-glibcs.py (Context.git_checkout): Use git clean -dxfq for git updates when replacing sources.
2018-01-29Clean up build-many-glibcs.py libcilkrts disabling.Joseph Myers
The disabling of libcilkrts in build-many-glibcs.py has some peculiarities. It's only for the final GCC build, not the initial bootstrap one, whereas normally anything disabled for the final build should be disabled for the bootstrap one as well. And it's only for Hurd, when it's more natural by analogy with the libsanitizer disabling to disable this library unconditionally, not only for targets where it's known to break. This patch cleans up that disabling accordingly, adding a comment so it's obvious it can be removed once GCC 7 is too old to build glibc. * scripts/build-many-glibcs.py (Config.build_gcc): Use --disable-libcilkrts unconditionally, not just for the final GCC build for Hurd.

2018-01-27hurd: fix gcc build in build-many-glibcs.pySamuel Thibault
gcc's libcilkrts has never actually supported GNU/Hurd, and doesn't automatically disable it, and the support was actually removed in gcc trunk, so that will never actually be fixed there. * scripts/build-many-glibcs.py [os == gnu] (build_gcc): Pass --disable-libcilkrts to gcc configure.
