glibc 0.6.1

===============================================Pure-Python bindings to glibc (based on ctypes)===============================================.. image:: https://badge.fury.io/py/glibc.png :target: http://badge.fury.io/py/glibc.. image:: https://travis-ci.org/zyga/python-glibc.png?branch=master :target: https://travis-ci.org/zyga/python-glibc.. image:: https://pypip.in/d/glibc/badge.png :target: https://pypi.python.org/pypi/glibcFeatures========* Free software: LGPLv3 license* Works on python 2.7+ and python 3.2+ and pypy* Currently exposes 23 low-level glibc functions (see below), 10 data types and 118 constants. All useful glibc features are in scope (patches welcome!)* ``from glibc import ...`` -- direct access to glibc constants, functions and types via lazy imports, fast startup, low memory overhead, efficient calls to glibc* Translates error codes according to documentation (manual pages) of each supported function. Raises OSError with appropriate values and a customized, easy-to-understand error message.* Uses declarative "bindings", easy to verify for correctness, easy to add more types, functions and constants. Built-in tests verify the value of each constant, size and offset of each structure / union field and the size of the whole structure / union.* Adds high-level abstractions on top of raw functions (pyglibc.select, pyglibc.signalfd, pyglibc.selectors, pyglibc.pthread_sigmask, pyglibc.pipe, pyglibc.subreaper) so that using them is easier and more pythonic.* This code is entirely optional and users can still call the low-level C-equivalents directly.* Where possible, existing Python APIs are followed so that glibc_select and glibc_selectors are drop-in replacements for the select and selectors modules from Python's standard library.Functions=========The following glibc functions are supported=========================== ================================= Name Remarks=========================== =================================``clock_getres(2)````clock_gettime(2)````clock_settime(2)````close(2)`` Same as os.close()``dup(2)`` Same as os.dup()``dup2(2)`` Same as os.dup2()``dup3(2)`` Same as os.dup(flags=)``epoll_create(2)`` Similar to select.epoll()``epoll_create1(2)`` Similar to select.epoll()``epoll_ctl(2)`` Similar to select.epoll.{register,unregister,modify}``epoll_pwait(2)````epoll_wait(2)`` Similar to select.epoll.poll()``eventfd(2)````eventfd_read(2)````eventfd_write(2)````pause(2)````pipe(2)`` Same as os.pipe``pipe2(2)````prctl(2)````pthread_sigmask(2)````read(2)`` Unlike os.read, this one makes no copies``sigaddset(3)````sigdelset(3)````sigemptyset(3)````sigfillset(3)````sigismember(3)````signalfd(2)````sigprocmask(2)````timerfd_create(2)````timerfd_gettime(2)````timerfd_settime(2)``0.6.1 (2014-11-20)==================* Small change to internal APIs (no need to upgrade or there are no public API changes).0.6 (2014-11-09)================* Functions from the pthread library are now supported* Added functions: ``read(2)``, ``pause(2)``, ``eventfd(2)``, ``eventfd_read(2)``, ``eventfd_write(2)``, ``clock_getres(2)``, ``clock_gettime(2)`` and ``clock_settime(2)``.* Added constants: ``NSIG``, ``EFD_CLOEXEC``, ``EFD_NONBLOCK``, ``EFD_SEMAPHORE``, ``CLOCK_REALTIME``, ``CLOCK_MONOTONIC``, ``CLOCK_PROCESS_CPUTIME_ID``, ``CLOCK_THREAD_CPUTIME_ID``, ``CLOCK_MONOTONIC_RAW``, ``CLOCK_REALTIME_COARSE``, ``CLOCK_MONOTONIC_COARSE``, ``CLOCK_BOOTTIME``, ``CLOCK_REALTIME_ALARM``, ``CLOCK_BOOTTIME_ALARM``,* Added new module :mod:`pyglibc.select` that contains a Python 2.7+ version of the select.py from Python 3.4. This module contains a pure-python version of the ``epoll`` class. It may be used in place of the module from the standard library if additional features are desired in a cross-python-version portable manner.* Added new module :mod:`pyglibc.selectors` that contains a Python 2.7+ version of the selectors.py from Python 3.4. As with pyglibc.select, it can be used in place of the original.* Added new module :mod:`pyglibc._signalfd` that exposes ``signalfd(2)`` in a much more pythonic way. Use signalfd as a file, as a context manager, inspect it in pdb, all easily without having to browse through manual pages. It is exposed as ``pyglibc.signalfd`` for easier importing.* Added new module :mod:`pyglibc._pthread_sigmask` that exposes ``pthread_sigmask(2)`` in a much more pythonic way, making it a perfect companion for the ``signalfd()`` class. It is exposed as ``pyglibc.pthread_sigmask`` for easier importing.* Added new module :mod:`pyglibc._pipe` that expoes ``pipe2(2)`` in the same way as Python 3.4 does via the ``os.pipe()`` and ``os.pipe2()`` functions.* Added new module :mod:`pyglibc._subreaper` that adds pythonic API to ``prctl(PR_{GET,SET}_CHILD_SUBREAPER, ...)``. This module exposes a single instance called ``subreaper``.0.5 (2014-10-22)================* Added tests for structure / union size and offset of each field* New feature, type aliases for non-compound types like ``time_t``.* Added functions: ``prctl(2)``, ``timerfd_create(2)``, ``timerfd_settime(2)``, ``timerfd_gettime(2)``.* Added constants: ``PR_SET_PDEATHSIG``, ``PR_GET_PDEATHSIG``, ``PR_GET_DUMPABLE``, ``PR_SET_DUMPABLE``, ``PR_GET_UNALIGN``, ``PR_SET_UNALIGN``, ``PR_GET_KEEPCAPS``, ``PR_SET_KEEPCAPS``, ``PR_GET_FPEMU``, ``PR_SET_FPEMU``, ``PR_GET_FPEXC``, ``PR_SET_FPEXC``, ``PR_GET_TIMING``, ``PR_SET_TIMING``, ``PR_SET_NAME``, ``PR_GET_NAME``, ``PR_GET_ENDIAN``, ``PR_SET_ENDIAN``, ``PR_GET_SECCOMP``, ``PR_SET_SECCOMP``, ``PR_CAPBSET_READ``, ``PR_CAPBSET_DROP``, ``PR_GET_TSC``, ``PR_SET_TSC``, ``PR_GET_SECUREBITS``, ``PR_SET_SECUREBITS``, ``PR_SET_TIMERSLACK``, ``PR_GET_TIMERSLACK``, ``PR_TASK_PERF_EVENTS_DISABLE``, ``PR_TASK_PERF_EVENTS_ENABLE``, ``PR_MCE_KILL``, ``PR_MCE_KILL_GET``, ``PR_SET_MM``, ``PR_SET_CHILD_SUBREAPER``, ``PR_GET_CHILD_SUBREAPER``, ``PR_SET_NO_NEW_PRIVS``, ``PR_GET_NO_NEW_PRIVS``, ``PR_GET_TID_ADDRESS``, ``PR_SET_THP_DISABLE``, ``PR_GET_THP_DISABLE``, ``PR_UNALIGN_NOPRINT``, ``PR_UNALIGN_SIGBUS``, ``PR_FPEMU_NOPRINT``, ``PR_FPEMU_SIGFPE``, ``PR_FP_EXC_SW_ENABLE``, ``PR_FP_EXC_DIV``, ``PR_FP_EXC_OVF``, ``PR_FP_EXC_UND``, ``PR_FP_EXC_RES``, ``PR_FP_EXC_INV``, ``PR_FP_EXC_DISABLED``, ``PR_FP_EXC_NONRECOV``, ``PR_FP_EXC_ASYNC``, ``PR_FP_EXC_PRECISE``, ``PR_TIMING_STATISTICAL``, ``PR_TIMING_TIMESTAMP``, ``PR_ENDIAN_BIG``, ``PR_ENDIAN_LITTLE``, ``PR_ENDIAN_PPC_LITTLE``, ``PR_TSC_ENABLE``, ``PR_TSC_SIGSEGV``, ``PR_MCE_KILL_CLEAR``, ``PR_MCE_KILL_SET``, ``PR_MCE_KILL_LATE``, ``PR_MCE_KILL_EARLY``, ``PR_MCE_KILL_DEFAULT``, ``PR_SET_MM_START_CODE``, ``PR_SET_MM_END_CODE``, ``PR_SET_MM_START_DATA``, ``PR_SET_MM_END_DATA``, ``PR_SET_MM_START_STACK``, ``PR_SET_MM_START_BRK``, ``PR_SET_MM_BRK``, ``PR_SET_MM_ARG_START``, ``PR_SET_MM_ARG_END``, ``PR_SET_MM_ENV_START``, ``PR_SET_MM_ENV_END``, ``PR_SET_MM_AUXV``, ``PR_SET_MM_EXE_FILE``, ``PR_SET_PTRACER``, ``PR_SET_PTRACER_ANY``, ``TFD_TIMER_ABSTIME``, ``TFD_CLOEXEC`` and ``TFD_NONBLOCK``,* Added structures: ``struct itimerspec``, ``struct timespec`` and ``struct timeval``.* Added type alias for ``time_t`` and ``suseconds_t``0.4 (2014-10-21)================* Started tracking changes relevant to other people.* First release with tests for constants and type sizes.* Fixed issues with ``struct epoll_event`` (size mismatch).* Added functions: ``close(2)``.* Added constants: ``FD_SETSIZE``, ``EPOLLRDNORM``, ``EPOLLRDBAND``, ``EPOLLWRNORM``, ``EPOLLWRBAND``, ``EPOLLMSG``.* Improved bundled demos (not part of release)
