* Optimize setjmp/longjmp for moxie.Anthony Green2019-12-202-87/+39
| | | | | We don't need to save/restore every register -- just those we don't expect to be trashed by function calls.
* Cygwin: pty: Fix ESC[?3h and ESC[?3l handling again.Takashi Yano2019-12-191-1/+1
| | | | | | - Even with commit fe512b2b12a2cea8393d14f038dc3914b1bf3f60, pty still has a problem in ESC[?3h and ESC[?3l handling if invalid sequence such as ESC[?$ is sent. This patch fixes the issue.
* Don't display trailing '.' in _dcvtKeith Packard2019-12-181-3/+12
| | | | | | | In the two helper functions that _dcvt calls for 'f' and 'e' mode, if there are no digits to display after the decimal point, don't add one. Signed-off-by: Keith Packard <keithp@keithp.com>
* Fix gcvt to always show 'ndigits' of precisionKeith Packard2019-12-181-11/+7
| | | | | | | | | Leading zeros after the decimal point should not count towards the 'ndigits' limit. This makes gcvt match glibc and the posix gcvt man page. Signed-off-by: Keith Packard <keithp@keithp.com>
* Fix fcvt to only show 'ndigit' past decimalKeith Packard2019-12-181-8/+1
| | | | | | | Even if the number is really small and this means showing *no* digits. This makes newlib match glibc, and the fcvt posix man page. Signed-off-by: Keith Packard <keithp@keithp.com>
* Cygwin: pty: Fix a bug regarding ESC[?3h and ESC[?3l handling.Takashi Yano2019-12-181-2/+5
| | | | | | | - Midnight commander (mc) does not work after the commit 1626569222066ee601f6c41b29efcc95202674b7 as reported in https://www.cygwin.com/ml/cygwin/2019-12/msg00173.html. This patch fixes the issue.
* doc: Untabify python scripts used for making man pagesJon Turney2019-12-182-219/+219
| | | | | These scripts fail with a TabError exception if 'python' is python3, as mixing tabs and spaces in indentation is forbidden in python3.

* Cygwin: symlink_info::check: avoid assertion failureKen Brown2019-12-091-1/+2
| | | | | | | | | | | On certain error conditions there is a code snippet that checks whether the last component of the path has a trailing dot or space or a leading space. Skip this check if the last component is empty, i.e., if the path ends with a backslash. This avoids an assertion failure if the trailing backslash is the only backslash in the path, as is the case for a DOS drive 'X:\'. Addresses: https://cygwin.com/ml/cygwin/2019-12/msg00016.html
* libm: switch sf_log1p from double error routines to floatKeith Packard2019-12-022-4/+2
| | | | | | | | | sf_log1p was using __math_divzero and __math_invalid, which drag in a pile of double-precision code. Switch to using the single-precision variants. This also required making those available in __OBSOLETE_MATH mode. Signed-off-by: Keith Packard <keithp@keithp.com>

* newlib: fix fseek optimization with SEEK_CURBastien Bouclet2019-11-182-50/+12
| | | | | | | The call to fflush was invalidating the read buffer, preventing relative seeks to positions that would have been inside the read buffer from being optimized. The call to srefill would then re-read mostly the same data that was initially in the read buffer.
* Cygwin: pty: Trigger redraw screen if ESC[?3h or ESC[?3l is sent.Takashi Yano2019-11-151-0/+22
| | | | | | | | | | - Pseudo console clears console screen buffer if ESC[?3h or ESC[?3l is sent. However, xterm/vt100 does not clear screen. This cause mismatch between real screen and console screen buffer. Therefore, this patch triggers redraw screen in that situation so that the synchronization is done on the next execution of native app. This solves the problem reported in: https://www.cygwin.com/ml/cygwin-patches/2019-q4/msg00116.html
* Cygwin: console: Revise the code checking if the console is legacy.Takashi Yano2019-11-131-14/+15
| | | | | | | - Accessing shared_console_info before initializing causes access violation in checking if the console is legacy mode. This patch fixes this issue. This solves the problem reported in: https://www.cygwin.com/ml/cygwin-patches/2019-q4/msg00099.html
* Cygwin: pty: Use redraw screen instead of clear screen.Takashi Yano2019-11-133-16/+18
| | | | | | | | | | - Previously, pty cleared screen at startup for synchronization between the real screen and console screen buffer for pseudo console. With this patch, instead of clearing screen, the screen is redrawn when the first native program is executed after pty is created. In other words, synchronization is deferred until the native app is executed. Moreover, this realizes excluding $TERM dependent code.
* regtool: allow /proc/registry{,32,64}/ registry path prefixBrian Inglis2019-11-132-5/+19
| | | | | The user can supply the registry path prefix /proc/registry{,32,64}/ to use path completion.
* Stash reent marker in upper bits of s1 on AMD GCNKwok Cheung Yeung2019-11-081-10/+10
| | | | | | | s[0:3] contain a descriptor used to set up the initial value of the stack, but only the lower 48 bits of s[0:1] are currently used. The reent marker is currently set in s3, but by stashing it in the upper 16 bits of s[0:1] instead, s3 can be freed up for other purposes.

* Cygwin: fix quoting when starting invisible console processCorinna Vinschen2019-11-051-5/+7
| | | | | | | | | | | | | | | | | | | | fhandler_console::create_invisible_console_workaround() does not use the lpApplicationName parameter and neglects to quote its command name on lpCommandLine in the call to CreateProcessW. Given CreateProcessW's brain-dead method to evaluate the application path given on the command line, this opens up a security problem if Cygwin is installed into a path with spaces in it. Fix this by using the lpApplicationName parameter and quoting of the application path in the lpCommandLine parameter (used as argv[0] in the called console helper. For extended paranoia, make the argument string array big enough to fit full 64 bit pointer values into it. Handles usually only use the lower 32 bit, but better safe than sorry.

* Move timeval macros to <sys/time.h>Sebastian Huber2019-11-042-32/+31
| | | | | In FreeBSD, NetBSD, and OpenBSD these macros are defined in <sys/time.h>.
* Synchronize <sys/time.h> with FreeBSDSebastian Huber2019-11-041-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | This change is based on the FreeBSD commit: Author: asomers <asomers@FreeBSD.org> Date: Mon Jul 30 15:46:40 2018 +0000 Make timespecadd(3) and friends public The timespecadd(3) family of macros were imported from NetBSD back in r35029. However, they were initially guarded by #ifdef _KERNEL. In the meantime, we have grown at least 28 syscalls that use timespecs in some way, leading many programs both inside and outside of the base system to redefine those macros. It's better just to make the definitions public. Our kernel currently defines two-argument versions of timespecadd and timespecsub. NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define three-argument versions. Solaris also defines a three-argument version, but only in its kernel. This revision changes our definition to match the common three-argument version. Bump _FreeBSD_version due to the breaking KPI change.

* Cygwin: fix process parent/child relationship after execveCorinna Vinschen2019-11-024-23/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 5a0f2c00aa "Cygwin: fork/exec: fix child process permissions" removed the PROCESS_DUP_HANDLE handle permission of the parent process handle in the child to avoid a security problem. It turned out that this broke the following scenario: If a process forks and then the parent execs, the child loses the ability to register the parent's death. To wit, after the parent died the child process does not set its own PPID to 1 anymore. The current exec mechanism copies required handle values (handles to keep contact to the child processes) into the child_info for the about-to-be-exec'ed process. The exec'ed process is supposed to duplicate these handles. This fails, given that we don't allow the exec'ed process PROCESS_DUP_HANDLE access to the exec'ing process since commit 5a0f2c00aa. The fix is to avoid the DuplicateHandle calls in the exec'ed process. This patch sets the affected handles to "inheritable" in the exec'ing process at exec time. The exec'ed process just copies the handle values and resets handle inheritance to "non-inheritable". The exec'ing process doesn't have to reset handle inheritance, it exits after setting up the exec'ed process anyway. Testcase: $ ssh-agent /bin/sleep 3 ssh-agent forks and the parent exec's sleep. After sleep exits, `ps' should show ssh-agent to have PPID 1, and eventually ssh-agent exits. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Fix libgloss being built for disabled multilibsJozef Lawrynowicz2019-11-022-0/+2
| | | | | | | | | Target libraries are considered to be built for GCC's "host", not GCC's "target". The "host" variable must be set by configure scripts using "config-ml.in" to determine multilib support, otherwise disabled multilibs (specified as a configure argument with --disable-<multilib>) will still be built for the subdirectories those configure scripts reside in.
