* Cygwin: Make dumper scan more than first 4GB of VM on x86_64Jon Turney2020-07-121-2/+2
| | | | | It's unclear that we need an end address here at all, or can just rely on VirtualQueryEx() failing when we reach the end of memory regions.
* Cygwin: Add a new win32_pstatus data type for modules on x86_64Jon Turney2020-07-122-4/+16
| | | | | | | Also take a bit more care with sizes in other data types to ensure they are the same on x86 and x86_64. Add some explanatory comments.
* Cygwin: Update ELF target used by dumper on x86_64Jon Turney2020-07-121-2/+8
| | | | | | Like [1], but actually making the effort to be 'usable' and 'tested'. [1] https://cygwin.com/pipermail/cygwin/2019-October/242815.html

* testsuite: Fix iconv tests to use new encoding config definesKeith Packard via Newlib2020-07-103-48/+47
| | | | | | | | _ICONV_CONVERTER -> ICONV_FROM_ENCODING. It's not perfect, as the library can support different from/to encodings now, but at least in the default configurations the tests now work. Signed-off-by: Keith Packard <keithp@keithp.com>
* libc/iconv: find_alias was mis-computing remaining alias table lengthKeith Packard via Newlib2020-07-101-1/+1
| | | | | | | | This caused the strnstr to walk off the end of the alias array and fetch invalid data. Instead of attempting to update 'len', just re-compute it based on the table end pointer that is already known. Signed-off-by: Keith Packard <keithp@keithp.com>
* libc/iconv: Remove unneeded pointer var for _iconv_aliasesKeith Packard via Newlib2020-07-102-6/+3
| | | | | | | The pointer value for the iconv alias data never changes, so get rid of the pointer and make it an array instead. Signed-off-by: Keith Packard <keithp@keithp.com>
* libc/iconv: Detect CES handler loading failureKeith Packard via Newlib2020-07-101-1/+1

* Fix invalid acl_entry_t on 32-bit CygwinDavid Allsopp2020-07-102-1/+5
| | | | | | | If the acl_t struct was at or above 0x80000000 then the pointer was sign-extended to 0xffff_ffff_8000_0000 and so the index was lost. Signed-off-by: David Allsopp <david.allsopp@metastack.com>
* Cygwin: convert sys_wcstombs/sys_mbstowcs wrapper to inline functionsCorinna Vinschen2020-07-104-66/+62
| | | | | | | | | | | This should slightly speed up especially path conversions, given there's one less function call rearranging all function arguments in registers/stack (and less stack pressure). For clarity, rename overloaded sys_wcstombs to _sys_wcstombs and sys_cp_mbstowcs to _sys_mbstowcs. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* fhandler_proc.cc(format_proc_cpuinfo): add microcode registry lookup valuesBrian Inglis2020-07-091-9/+35
| | | | | | | | | | | Re: CPU microcode reported wrong in /proc/cpuinfo https://sourceware.org/pipermail/cygwin/2020-May/245063.html earlier Windows releases used different registry values to store microcode revisions depending on the MSR name being used to get microcode revisions: add these alternative registry values to the cpuinfo registry value lookup; iterate thru the registry data until a valid microcode revision is found; some revision values are in the high bits, so if the low bits are all clear, shift the revision value down into the low bits

* Cygwin: fix buffer overrun in cygwin_strcasecmpCorinna Vinschen2020-07-062-14/+23
| | | | | | | | | | | | | | | | | | | | | | | | | sys_mbstowcs is called with the destination buffer length set to MaximumLength from the receiving UNICODE_STRING buffer. This is twice as much as the actual size of the buffer in wchar_t units, which is the unit expected by sys_mbstowcs. sys_mbstowcs always attaches a NUL, within the destination buffersize given. But if the string is exactly one wchar_t less than the actual buffer, and the buffersize is given too large, sys_mbstowcs writes a NUL one wchar_t beyond the buffer. This has only been exposed with Cygwin 3.1.5 because alloca on newer gcc 9 apparently allocates more tightly. The alloca buffer here is requested with 16 bytes, which is exactly the number of bytes required for the string L"cmd.exe". Older gcc apparently allocated a few more bytes on the stack, while gcc 9 allocates in 16 byte granularity... Fix this by giving the correct destination buffer size to sys_mbstowcs.

* Cygwin: pty, termios: Unify thoughts of read ahead beffer handling.Takashi Yano via Cygwin-patches2020-07-012-31/+26
| | | | | | | | | | | | | | | - Return value of eat_readahead() is redefined. The return values of fhandler_termios::eat_readahead() and fhandler_pty_slave:: eat_readahead() were little bit different. This patch unifies them to number of bytes eaten by eat_readahead(). - Considerration for raixget() is added to fhandler_pty_master:: accept_input() code. - Transfering contents of read ahead buffer in fhandler_pty_master::transfer_input_to_pcon() is removed since it is not necessary. - fhandler_pty_slave::eat_readahead() ckecks EOL only when ICANON is set. - Guard for _POSIX_VDISABLE is added in checking EOL.
* Cygwin: pty: Discard CSI > Pm m sequence from native windows apps.Takashi Yano via Cygwin-patches2020-07-011-0/+28
| | | | | | | | | - If vim is started from WSL (Ubuntu) which is executed in pseudo console in mintty, shift key and ctrl key do not work. Though this issue is similar to the issue resolved by commit 4527541ec66af8d82bb9dba5d25afdf489d71271, that commit is not effective for this issue. This patch fixes the issue by discarding "CSI > Pm m" in fhandler_pty_master::pty_master_fwd_thread().

* Cygwin: pty: Fix screen distortion after less for native apps again.Takashi Yano via Cygwin-patches2020-06-054-37/+21
| | | | | | | | | | | | | - Commit c4b060e3fe3bed05b3a69ccbcc20993ad85e163d seems to be not enough. Moreover, it does not work as expected at all in Win10 1809. This patch essentially reverts that commit and add another fix. After all, the cause of the problem was a race issue in switch_to_pcon_out flag. That is, this flag is set when native app starts, however, it is delayed by wait_pcon_fwd(). Since the flag is not set yet when less starts, the data which should go into the output_handle accidentally goes into output_handle_cyg. This patch fixes the problem more essentially for the cause of the problem than previous one.

* Cygwin: pty: Fix screen distortion after using less for native apps.cygwin-3_1_5-releaseTakashi Yano via Cygwin-patches2020-06-011-8/+11
| | | | | | - If the output of non-cygwin apps is browsed using less, screen is ocasionally distorted after less exits. This frequently happens if cmd.exe is executed after less. This patch fixes the issue.
* Cygwin: pty: Revise the code which prevents undesired window title.Takashi Yano via Cygwin-patches2020-05-311-2/+7
| | | | | | | - In current pty, the window title can not be set from non-cygwin program due to the code which prevents overwriting the window title to "cygwin-console-helper.exe" in fhandler_pty_master::pty_ master_fwd_thread(). This patch fixes the issue.
* Cygwin: pty: Clean up fhandler_pty_master::pty_master_fwd_thread().Takashi Yano via Cygwin-patches2020-05-311-18/+0
| | | | - Remove the code which is not necessary anymore.
* Cygwin: console: Discard some unsupported escape sequences.Takashi Yano via Cygwin-patches2020-05-311-16/+38
| | | | | | | | | | | - If the cygwin vim is started from a non-cygwin process which is executed in pseudo console, shift key and ctrl key do not work. In this case, vim is executed under /dev/cons*. If vim outputs escape sequence which is not supported by pseudo console, the escape sequence is leaked into the parent pty. This causes unexpected results. This patch fixes the issue by discarding "CSI > Pm m". "OSC 10;? BEL/ST" and "OSC 11;? BEL/ST" are discarded as well.
* Cygwin: pty: Prevent garbage remained in read ahead buffer.Takashi Yano via Cygwin-patches2020-05-312-3/+14
| | | | | | | | | | | | | | | | - After commit 29431fcb5b14d4c5ac3b3161a076eb1a208349d9, the issue reported in https://cygwin.com/pipermail/cygwin/2020-May/245057.html occurs. This is caused by the following mechanism. Cygwin less called from non-cygwin git is executed under /dev/cons* rather than /dev/pty* because parent git process only inherits pseudo console handle. Therefore, less sets ICANON flag for /dev/cons* rather than original /dev/pty*. When pty is switched to non-cygwin git process, line_edit() is used in fhandler_pty_master::write() only to set input_available_event and read ahead buffer is supposed to be flushed in accept_input(). However, ICANON flag is not set for /dev/pty*, so accept_input() is not called unless newline is entered. As a result, the input data remains in the read ahead buffer. This patch fixes the issue.
* Cygwin: update C++ dialect to gnu++14Corinna Vinschen2020-05-303-25/+25

* Cygwin: console: Make cursor keys work in vim under ConEmu.Takashi Yano via Cygwin-patches2020-05-302-6/+15

* Cygwin: stat: fix st_mode of fifos againKen Brown2020-05-282-1/+4
| | | | | | | This partially reverts commit f36262d56ac78f04de147746ce4a85c6155e4a23. That commit incorrectly made the st_mode of a fifo reflect the Windows permissions of the disk file underlying the fifo.
* Cygwin: pty: Prevent meaningless ResizePseudoConsole() calls.Takashi Yano via Cygwin-patches2020-05-281-9/+9
| | | | | - This patch prevents to call ResizePseudoConsole() unless the pty is resized.
