* Cygwin: Add IUTF8 termios iflagCorinna Vinschen2017-01-311-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The termios code doesn't handle erasing of multibyte characters in canonical mode, it always erases a single byte. When entering a multibyte character and then pressing VERASE, the input ends up with an invalid character. Following Linux we introduce the IUTF8 input flag now, set by default. When this flag is set, VERASE or VWERASE will check if the just erased input byte is a UTF-8 continuation byte. If so, it erases another byte and checks again until the entire UTF-8 character has been removed from the input buffer. Note that this (just as on Linux) does NOT work with arbitrary multibyte codesets. This only works with UTF-8. For a discussion what happens, see https://cygwin.com/ml/cygwin/2017-01/msg00299.html Sidenote: The eat_readahead function is now member of fhandler_termios, not fhandler_base. That's necessary to get access to the terminal's termios flags. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Consolidate wctomb/mbtowc calls for POSIX-1.2008Corinna Vinschen2016-08-151-1/+1
| | | | | | | | | | | | | | | | | | | | | - Remove charset parameter from low level __foo_wctomb/__foo_mbtowc calls. - Instead, create array of function for ISO and Windows codepages to point to function which does not require to evaluate the charset string on each call. Create matching helper functions. I.e., __iso_wctomb, __iso_mbtowc, __cp_wctomb and __cp_mbtowc are functions returning the right function pointer now. - Create __WCTOMB/__MBTOWC macros utilizing per-reent locale and replace calls to __wctomb/__mbtowc with calls to __WCTOMB/__MBTOWC. - Drop global __wctomb/__mbtowc vars. - Utilize aforementioned changes in Cygwin to get rid of charset in other, calling functions and simplify the code. - In Cygwin restrict global cygheap locale info to the job performed by internal_setlocale. Use UTF-8 instead of ASCII on the fly in internal conversion functions. - In Cygwin dll_entry, make sure to initialize a TLS area with a NULL _REENT->_locale pointer. Add comment to explain why.

* Don't raise SIGTTIN from poll/selectCorinna Vinschen2016-07-271-2/+2
| | | | | | | | | | | | | SIGTTIN should be raised when read() is made on a tty in a backgrounded process, but not when it's tested with poll()/select(). I guess poll()/select() does need to call bg_check(), in order to detect the error conditions that notices (that is, if bg_check() returns bg_eof or bg_error, then fd is ready as an error condition exists) so add an optional parameter to fhandler_base::bg_select() to indicate that signals aren't desired. See https://cygwin.com/ml/cygwin-developers/2016-07/msg00004.html
* Handle up to 63 partitions per driveCorinna Vinschen2016-06-231-3/+4
| | | | | | | | | | | | | | Revamp device parsing code. Introducing support for more partitions into the shilka-generated parser has the unfortunate side-effect of raising the size of the DLL by almost 2 Megs. Therefore we split out the handling for /dev/sdXY devices into a tiny bit of hand-written code. While at it, remove some unused cruft from devices.* and generally clean up the device class to provide access methods instead of direct access to members.

* Be truthful about reporting whether readahead is availableJohannes Schindelin2016-04-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In 7346568 (Make requested console reports work, 2016-03-16), code was introduced to report the current cursor position. It works by using a pointer that either points to the next byte in the readahead buffer, or to a NUL byte if the buffer is depleted, or the pointer is NULL. These conditions are heeded in the fhandler_console::read() method, but the condition that the pointer can point at the end of the readahead buffer was not handled properly in the get_cons_readahead_valid() method. This poses a problem e.g. in Git for Windows (which uses a slightly modified MSYS2 runtime which is in turn a slightly modified Cygwin runtime) when vim queries the cursor position and immediately goes on to read console input, erroneously thinking that the readahead buffer is valid when it is already depleted instead. This condition results in an apparent freeze that can be helped only by pressing keys repeatedly. The full Git for Windows bug report is here: https://github.com/git-for-windows/git/issues/711 Let's just teach the get_cons_readahead_valid() method to handle a depleted readahead buffer correctly.

The new ACLs now store the POSIX ACL MASK/CLASS_OBJ permission mask, and they allow to inherit the S_ISGID bit. ACL inheritance now really works as desired, in a limited, but theoretically equivalent fashion even for non-Cygwin processes. To accommodate Windows default ACLs, the new code ignores SYSTEM and Administrators group permissions when computing the MASK/CLASS_OBJ permission mask on old ACLs, and it doesn't deny access to SYSTEM and Administrators group based on the value of MASK/CLASS_OBJ when creating the new ACLs. The new code now handles the S_ISGID bit on directories as on Linux: Setting S_ISGID on a directory causes new files and subdirs created within to inherit its group, rather than the primary group of the user who created the file. This only works for files and directories created by Cygwin processes. 2015-05-29 Corinna Vinschen <corinna@vinschen.de> Reapply POSIX ACL changes. * utils.xml (setfacl): Show new option output.
