What's new:
-----------
* autoload.cc (IdnToAscii): Define. (IdnToUnicode): Define. (FreeAddrInfoW): Define. (GetAddrInfoW): Define. (GetNameInfoW): Define. * net.cc: Drop W. Richard STEVENS libgai implementation. (cygwin_freeaddrinfo): Move code from ipv4_freeaddrinfo here. Move definition up in file to avoid forward declaration in ga_duplist. (ga_dup): Take addrinfoW as input. Add parameters to get IDN flags and to set error value. Handle IDN flags and especially AI_CANONIDN. Convert input wchar_t ai_canonname string to multibyte for output. (ga_duplist): Add parameters to get IDN flags and to set error value and propagate to ga_dup. Call cygwin_freeaddrinfo. (gai_errmap): Add comments. Align error strings to GLibc. Add EAI_IDN_ENCODE entry. (get_ipv6_funcs): Remove. (load_ipv6_guard): Remove. (ipv6_inited): Remove. (load_ipv6): Remove. (load_ipv6_funcs): Remove. (cygwin_getaddrinfo): Drop calling load_ipv6. Handle AI_IDN* flags. Convert input strings to wchar_t and call GetAddrInfoW/FreeAddrInfoW. In case hints is NULL, set default ai_flags explicitely to AI_V4MAPPED | AI_ADDRCONFIG, as documented for Glibc. Only add AI_ALL if AI_ADDRCONFIG is not given. Unconditionally add Windows-specific AI_DISABLE_IDN_ENCODING to ai_flags to make IDN behaviour compatible to Glibc even on Windows 8 and later. (cygwin_getnameinfo): Drop calling load_ipv6. Handle NI_IDN* flags. Call GetNameInfoW and convert returned strings from wchar_t to multibyte. * include/netdb.h: Add comments to describe flags and error values. (AI_*): Define all flags using hex values for clearness. (AI_IDN): Define. (AI_CANONIDN): Define. (AI_IDN_ALLOW_UNASSIGNED): Define. (AI_IDN_USE_STD3_ASCII_RULES): Define. (NI_*): Define all flags using hex values for clearness. (NI_IDN): Define. (NI_IDN_ALLOW_UNASSIGNED): Define. (NI_IDN_USE_STD3_ASCII_RULES): Define. (EAI_IDN_ENCODE): Define.

AI_IDN_USE_STD3_ASCII_RULES.
- getnameinfo now supports glibc-specific International Domain Name (IDN)
extension flags: NI_IDN, NI_IDN_ALLOW_UNASSIGNED, NI_IDN_USE_STD3_ASCII_RULES.
* common.din: Export posix_spawn[...] functions. * exec.cc (execve): Add EXPORT_ALIAS _execve. * include/cygwin/version.h (CYGWIN_VERSION_API_MINOR): Bump. * posix.sgml (std-susv4): Add posix_spawn[...] here. (std-notimpl): Drop here.

- Allow to use advisory locking on any device. POSIX fcntl and lockf locking
works with any device, BSD flock locking only with devices backed by an OS
handle. Right now this excludes console windows on pre Windows 8, as well as
almost all virtual files under /proc from BSD flock locking.
* devices.in (dev_storage): Map /dev/zero and /dev/full to \Device\Null. * devices.cc: Regenerate. * dtable.h (struct dtable): Make fhandler_base friend, rather than fhandler_disk_file. * fhandler.cc (fhandler_base::open_with_arch): Create unique id. (fhandler_base::cleanup): Call del_my_locks. (fhandler_base::fcntl): Handle F_GETLK, F_SETLK and F_SETLKW. * fhandler.h (fhandler_base::get_dev): Return real device number. (fhandler_base::set_unique_id): New inline method. (fhandler_disk_file::lock): Drop declaration. (fhandler_disk_file::get_dev): New method, return pc.fs_serial_number. (fhandler_dev_zero::open): Drop declaration. * fhandler_disk_file.cc (fhandler_disk_file::close): Move del_my_locks call to fhandler_base::open_with_arch. (fhandler_disk_file::fcntl): Move handling of locking commands to fhandler_base::fcntl. (fhandler_base::open_fs): Drop call to NtAllocateLocallyUniqueId. * fhandler_zero.cc (fhandler_dev_zero::open): Remove so that default fhandler_base::open is used to open \Device\Null. * flock.cc (fixup_lockf_after_exec): Finding a single fhandler is enough here. (fhandler_base::lock): Replace fhandler_disk_file::lock. Refuse to lock nohandle devices. Handle read/write test using POSIX flags. Explain why. Never fail on SEEK_CUR or SEEK_END, rather assume position 0, just as Linux. * net.cc (fdsock): Create unique id.
2013-10-24 11:41:17 +02:00
* exception.h: Fold in content of include/exceptions.h. * include/exceptions.h: Remove.
2013-10-27 10:42:17 +01:00
- The header /usr/include/exceptions.h, containing implementation details for
32 bit Windows' exception handling only, has been removed.
* devices.in (dev_storage): Map /dev/zero and /dev/full to \Device\Null. * devices.cc: Regenerate. * dtable.h (struct dtable): Make fhandler_base friend, rather than fhandler_disk_file. * fhandler.cc (fhandler_base::open_with_arch): Create unique id.

Fixes: http://cygwin.com/ml/cygwin/2013-09/msg00155.html
* fhandler_process.cc (format_process_ctty): Fix random content of /proc/$PID/ctty if the process has no controlling tty. Set to just "\n" instead.

- Properly set process sid rather than always using -1.
Fixes: http://cygwin.com/ml/cygwin/2013-10/threads.html#00237
* fhandler_clipboard.cc (fhandler_dev_clipboard::open): Drop gratuitios handling of membuffer. It's NULL anyway. (fhandler_dev_clipboard::lseek): Set membuffer to NULL after freeing it to avoid subsequent crashes when accessing invalid pointer.
2013-10-25 17:04:24 +02:00
- Fix a potential crash after calling lseek on /dev/clipboard.

- Fix a handle inheritance bug in raw disk and tape device handling which
led to EBADF errors in child processes.
*** empty log message ***
2013-10-30 11:00:32 +01:00
- open("/dev", O_CREAT) accidentally created a /dev file if no /dev
exists at the time.
- DIR *d = opendir ("foo"); flock (dirfd (d), ...); worked, but did the
wrong thing.
- Reading from /dev/windows was broken for some time.
- select'ing on /dev/windows accidentally didn't take the setting of
ioctl (WINDOWS_HWND) into account.

- Fix typos in cygcheck which could crash Windows 8 and 8.1 machines.
Fixes: http://cygwin.com/ml/cygwin/2013-11/msg00334.html
* ntdll.h (RtlGetVersion): Declare. * wincap.cc (wincapc::init): Rather than GetVersionEx, call RtlGetVersion which is not crippled by missing Windows 8.1 manifest. * wincap.h (wincapc): Change type of version to RTL_OSVERSIONINFOEXW. Align formatting of all class members.
2013-11-19 23:21:11 +01:00
- Show OS version correctly even on Windows 8.1 and Server 2012 R2.

- dup2() could crash in some cases for a destination >= 256
Fixes: http://cygwin.com/ml/cygwin/2013-09/msg00397.html
* syscalls.cc (try_to_bin): Take additional parameter to get file open flags. If the file to move to the bin has been opened casesensitive, reopen it caseinsensitive. Explain why. Revert the default name of the Vista-and-later recycler to mixed case for readability. (unlink_nt): Call try_to_bin with file open flags as evaluated.
2013-11-27 15:27:34 +01:00
- Try to workaround the following problem: unlink(2) could fail, if the
file was opened casesensitive and has to be moved to the recycler due
to a sharing violation.
