* Fix console clear screen in case of partial scrollingCorinna Vinschen2016-08-011-2/+2
| | | | | | | | | | Commit d7586cb incorrectly checked only for the new cursor position beyond the old cursor position to decide if we have to correct for user scrolling. Since this situation is handled just fine if the cursor is still visible, only perform the subsequent correction if the cursor is not in the visible console window.

* Open process with PROCESS_QUERY_INFORMATION to fetch mapsCorinna Vinschen2016-08-011-2/+2
| | | | | | | | | | | | | | Commit ba58e5f lowered permission requirements when opening threads and processes to {PROCESS,THREAD}_QUERY_LIMITED_INFORMATION. However, when creating the /proc/<PID>/maps file, the call to VirtualQueryEx requires PROCESS_QUERY_INFORMATION access Note: It seems PROCESS_QUERY_LIMITED_INFORMATION is sufficient starting with Windows 8.1, but this is neither documented on MSDN, nor is it a safe bet. It may have to do with a fixed implementation of the UAC trust levels. Let's better follow the docs for now. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Fix clear screen behaviour of console when user scrolled up or downCorinna Vinschen2016-07-291-1/+21
| | | | | | | | | | We must call SetConsoleCursorPosition prior to SetConsoleWindowInfo, otherwise the scroll bars will not be updated by the OS. Make sure to scroll the console window by just the right amount to have the new cursor position one line after the used console buffer area at the top of the console window, no matter the scroll state.

* Don't raise SIGTTIN from poll/selectCorinna Vinschen2016-07-273-10/+41
| | | | | | | | | | | | | 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.

* truncl: Fix setting rounding bits in FPU control wordCorinna Vinschen2016-07-181-2/+6
| | | | | | | | | | | Mingw-w64, which is the source of this code, uses different definitions of the rounding bits FE_TONEAREST and friends. They immediately reflect the bit values in the FPU control word, while on Cygwin they are shifted down to become the values 0-3. Fix the bit computing expression to account for the difference.

* Fix 32-bit SSIZE_MAXEric Blake2016-07-142-1/+12
| | | | | | | | | | | | | | | | | | | POSIX requires that SSIZE_MAX have the same type as ssize_t, but on 32-bit, we were defining it as a long even though ssize_t resolves to an int. It also requires that SSIZE_MAX be usable via preprocessor #if, so we can't cheat and use a cast. If this were newlib, I'd have had to hack _intsup.h to probe the qualities of size_t (via gcc's __SIZE_TYPE__), similar to how we already probe the qualities of int8_t and friends, then cross our fingers that ssize_t happens to have the same rank (most systems do, but POSIX permits a system where they differ such as size_t being long while ssize_t is int). Unfortunately gcc gives us neither __SSIZE_TYPE__ nor __SSIZE_MAX__. On the other hand, our limits.h is specific to cygwin, so we can just shortcut to the correct results rather than being generic to all possible ABI. Signed-off-by: Eric Blake <eblake@redhat.com>

* machine/_types.h: __blkcnt_t should be signedRay Donnelly2016-07-141-1/+1
| | | | | | | | | | [1] states: "blkcnt_t and off_t shall be signed integer types." This causes pacman to fail when the size requirement of the net update operation is negative, instead it calculated a huge positive number.

* strace: Make sure strace timer isn't copied to child processCorinna Vinschen2016-07-061-1/+1
| | | | | | | | | At fork time the .data and .bss segments of the Cygwin DLL are copied over to the child process. This also copies the strace timer since it's in the .bss segment so far. Fix that by moving the strace timer out into the .data_cygwin_nocopy segment. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Redefine locale info in struct _reent for per-thread localesCorinna Vinschen2016-07-061-1/+0
| | | | | | | | | | | | | The _reent members _current_category and _current_locale are not used at all. _current_locale is set to "C" in various points of the code but its value is just as unused as _current_category. This patch redefines these members without changing the size of the structure to allow for an implementation of per-thread locales per POSIX-1.2008 (i.e. uselocale and usage of the per-thread locale in subsequent function calls).

* ldd: Handle executable relocation when setting breakpointCorinna Vinschen2016-07-021-23/+24
| | | | | | | | | | | | | | | | set_entry_point_break() uses GetModuleInformation to fetch the address of the exe's entry point. However, just as with lpStartAddress from the CREATE_PROCESS_DEBUG_EVENT event, the returned address is only computed from the PE file header. It's not actually the entry point in memory, if the executable is relocated (ASLR). See https://msdn.microsoft.com/en-us/library/windows/desktop/ms684229(v=vs.85).aspx Convert this to using the info from CREATE_PROCESS_DEBUG_EVENT combined with the offset from the PE file header's AddressOfEntryPoint to deal with relocation.

* ldd: terminate process on hitting breakpointCorinna Vinschen2016-07-021-4/+1
| | | | | | | | | So far ldd terminates the inferior process as soon as some thread is started. Apparently threads are started from even ntdll.dll before the main thread of the application is started. As a result the dll list is cut short since ldd terminates prematurely.

* Make sure to use the Winsock definition of FIONREAD in ioctlsocket callCorinna Vinschen2016-07-011-1/+2
| | | | | | | | | | Commit b1b46d45 introduced a regression. After redefining FIONREAD as part of restructuring newlib/Cygwin headers, the call to ioctlsocket in the FIONREAD branch of fhandler_socket::ioctl should have been changed to use the Winsock definition of FIONREAD, which I neglected. This only affects 64 bit Cygwin. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
