- Add missing handling for WAIT_CANCELED in cygwait() for read_mtx
in raw_read().
|

This code looks like it's written to be copied & pasted between diff
C libraries and relies on _LIBC only being used with glibc. This will
break when newlib changes from _COMPILING_NEWLIB to _LIBC, so delete
the glibc-specific logic ahead of time.

- If output of C# program is redirected to pipe, pipe reader falsely
detects EOF. This happens after overhaul of pipe implementation.
This patch fixes the issue.

Regenerate the files using automake-1.15 & autoconf-2.69 to match the
binutils/gdb/gcc projects. Ran:
libgloss $ find -name configure.ac -printf '%h\n' | while read d; do
(cd $d; export WANT_AUTOCONF=2.69 WANT_AUTOMAKE=1.15;
aclocal-1.15 -I.. && autoconf-2.69); done
|
|
The maintainer rules refer to configure.in directly, so update that
after renaming all the configure.ac files.

Cygwin always requests FILE_WRITE_ATTRIBUTES permissions when trying to
change DAC information. This can lead to permission problems when
trying to chmod/chown files on Samba shares. Drop requesting
FILE_WRITE_ATTRIBUTES on Samba shares and go with WRITE_DAC/WRITE_OWNER
only.

Also rename release 3.4.0 to 3.3.2. It doesn't make sense to
duplicate the issues fixed in 3.3.x into the 3.4.0 relnotes.
Only patches not backported into 3.3.x belong into 3.4.0.

ldtoa cuts the number of digits it returns based on a computation of
number of supported bits (144) divide by log10(2). Not only is the
integer approximation of log10(2) ~= 8/27 missing a digit here, it
also fails to take really small double and long double values into
account.
Allow for the full potential precision of long double values. At the
same time, change the local string array allocation to request only as
much bytes as necessary to support the caller-requested number of
digits, to keep the stack size low on small targets.
In the long run a better fix would be to switch to gdtoa, as the BSD
variants, as well as Mingw64 do.

- Currently, bash occasionally exits by Ctrl-C with the following
scenario.
1) Start bash in the command prompt.
2) Run 'exec bash'.
3) Press Ctrl-C several times.

Currently, newlib does not declare strsignal if DEFS_H is defined,
ostensibly to work around a gdb bug. However, gdb itself compiles
even with this ifndef removed, and this makes sim (another part of
gdb) fail to compile.
Since it is not clear exactly what issue this was working around,
this patch just replaces that ifdef with the correct check,
i.e. __POSIX_VISIBLE >= 200809.

The file configure.in was renamed to configure.ac in libgloss/riscv but
the hard coded name in the Makefile for that directory was not updated.
This patch simply renamed this to configure.ac.

Per https://cygwin.com/pipermail/cygwin-developers/2021-October/012429.html,
we may encounter a crash when starting multiple threads during process
startup (here: fhandler_fifo::fixup_after_{fork,exec}) which in turn
allocate memory via malloc.
The problem is concurrent usage of malloc before the malloc muto has
been initialized.
To fix this issue, convert the muto to a SRWLOCK and make sure it is
statically initalized. Thus, malloc can be called as early as necessary
and malloc_init is only required to check for user space provided malloc.
Note that this requires to implement a __malloc_trylock macro to be
called from fork.

This patch unifies the layout of the clipboard descriptor cygcb_t for
32- and 64-bit Cygwin. It allows correct copy/paste between the two
environments without corruption of user's copied data and without access
violations due to interpreting that data as a size field.
The definitions of CYGWIN_NATIVE and cygcb_t are moved to a new include
file, sys/clipboard.h. The include file is used by fhandler_clipboard.cc
as well as getclip.c and putclip.c in the Cygwin cygutils package.
When copy/pasting between 32- and 64-bit Cygwin environments, both must
be running version 3.3.0 or later for successful operation.

Reported by prodisDown:
In picolibc/newlib/libc/string/strrchr.c
if (i) { while ((s=strchr(s, i))) { last = s; s++; } } else { last = strchr(s, i); }
Value (for example 0xFFFFFF00) in if (i) can pass test and
then be typecasted to char inside strchr(). Then s++ and then
buffer overrun.
It can be fixed by preventive typecast i = (int) (char) i; or
typecasting inside expression if ((char) i).
Fixed by casting to char.

Add specialized rotations RB_RED_ROTATE_LEFT() and RB_RED_ROTATE_RIGHT() which
may be used if we rotate a red child which has a black sibling. Such a red
node must have at least two child nodes so that the following red-black tree
invariant is fulfilled:
Every path from a given node to any of its descendant NULL nodes goes through
the same number of black nodes.
PARENT
/ \
BLACK RED
/ \
BLACK BLACK
|
|
Add specialized rotations RB_PARENT_ROTATE_LEFT() and RB_PARENT_ROTATE_RIGHT()
which may be used if the parent node exists and the direction of the child is
known. The specialized rotations are derived from RB_ROTATE_LEFT() and
RB_ROTATE_RIGHT() where the RB_SWAP_CHILD() was replaced by a simple
assignment.

In RB_GENERATE_REMOVE_COLOR() simplify a chain of conditions of the following
pattern
if (x) {
...
} else if (!x) {
...
}
to
if (x) {
...
} else {
...
}
|
|
We have
#define RB_ISRED(elm, field) \
((elm) != NULL && RB_COLOR(elm, field) == RB_RED)
So, the RB_ISRED() contains an implicit check for NULL. In
RB_GENERATE_REMOVE_COLOR() the "elm" pointer cannot be NULL in the while
condition. Use RB_COLOR(elm) == RB_BLACK instead.

- The commit b531d6b0 introduced temporary_query_hdl() which uses
SystemHandleInformation. With this patch, ProcessHandleInformation
rather than SystemHandleInformation is used if it is available.
This request is faster, however, is only available since Windows 8,
therefore, SystemHandleInformation is used for Windows Vista and 7
as before.
|
|
- The commit f79a4611 introduced query_hdl, which is the read pipe
handle kept in the write pipe instance in order to determine if
the pipe is ready to write in select(). This implementation has
a potential risk that the write side fails to detect the closure
of the read side if more than one writer exists and one of them
is a non-cygwin process.
With this patch, the strategy of commit f79a4611 is used only if
the process is running as a service. For a normal process,
instead of keeping query_hdl in the write pipe instance, it is
retrieved temporarily when select() is called. Actually, we
want to use tenporary query_hdl for all processes, however, it
does not work for service processes due to OpenProcess()
failure.

In view of the previous changes to open_setup, we can always assume
that hdl_cnt_mtx is non-NULL.
|
|
open_setup is called by dtable::init_std_file_from_handle and
fhandler_base::open_with_arch. In both cases, failure of open_setup
is now a fatal error.
Currently this can only happen in the following situation: A Cygwin
process is started by a non-Cygwin process, one of the standard IO
handles is a pipe handle, and Cygwin is unable to create a required
mutex (read_mtx or hdl_cnt_mtx).
|
|
|
|
Convert fhandler_base::open_setup to a (virtual) method that returns a
bool result. For the moment, it and its overrides always return true.
|
|
This fixes the problem reported here:
