Jon Turney a15297381d Fix handling of '+' by 'cygcheck -p'
The form data sent to the server should be application/x-www-form-urlencoded

This replaces spaces with '+' before being RFC 1738 encoded, so a literal
'+' must be %-encoded also.

Corinna Vinschen 095cac4b8d Cygwin: Add IUTF8 termios iflag
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.

Hans-Peter Nilsson cd5e7e2d82 Committed, libgloss: hook up cris-elf to the initfini-array support.
After a binutils change "a while ago" (2015-12) to default to
--enable-initfini-array, i.e. to merge .ctors and .dtors into
.init_array and .fini_array, this is needed for cdtors to run at all.

Based on what goes on in arm/ and aarch64/.  Tested for cris-elf by
running the gcc testsuite.

By the way, the configure test doesn't detect this change, so the
HAVE_INITFINI_ARRAY ifdeffery is somewhat redundant.  Still, the
change is tested to be safe with older binutils too.

libgloss/
	* cris/crt0.S, cris/lcrt0.c: Include newlib.h.
	[HAVE_INITFINI_ARRAY] (_init): Define to __libc_init_array.
	[HAVE_INITFINI_ARRAY] (_fini): Ditto __libc_fini_array.

In patch b219285f87 you have a syntax
error in the PLD instruction.  The syntax for the pld argument should be
in square brackets as it's a memory address like so: pld [r1].  With

Pat Pannuto 3ebc26958e arm: Remove RETURN macro
LTO can re-order top-level assembly blocks, which can cause this
macro definition to appear after its use (or not at all), causing
compilation failures. On modern toolchains (armv4t+), assembly
should write `bx lr` in all cases, and linkers will transparently
convert them to `mov pc, lr`, allowing us to simply remove the
macro.
  (source: https://groups.google.com/forum/#!topic/comp.sys.arm/3l7fVGX-Wug
   and verified empirically)

For the armv4.S file, preserve this macro to maximize backwards
compatibility.

Thomas Preudhomme cd1b883526 Prefix consistenly target-independent locks with __
Hi,

With the patch to allow newlib's locking routine to be retargeted currently
under discussion, we need to start thinking of locks as part of newlib's ABI
since newlib depends on specific names being provided by the OS. This patch
renames 2 locks so that they follow the same naming convention as other locks.
It needs to be applied before the retargeting patch, while locks are still an
internal consideration.

Newlib builds successfully with this change.

Ok for master branch?

Best regards,

Thomas

Eric Blake ca3e3bc54e nl_langinfo: Add NL_LOCALE_NAME macro
Provide an extension NL_LOCALE_NAME() macro, with semantics
matching glibc, which can be used as:
  nl_langinfo_l(NL_LOCALE_NAME(LC_MESSAGES), locale);
to get back the locale string that locale was originally
created with during newlocale(). This in turn allows a library
(such as gettext) to determine what thread-local locale settings
it has inherited from the main program without having to be told
what parameters were passed to newlocale(), for less overall
coupling between parts of the program.

gnulib is set up to use the extension:

input which results in newer readline using pselect to fail handling such

During debugging and testing it turned out that while reading console
input, single key presses during an Alt+Numpad sequences where not
ignored, so ultimately a sequence like

  Alt-down Numpad-1 Numpad-2 Numpad-3

whihc is supposed to result in a single character in the input stream
will actually result in 4 chars in the input stream, three control
sequences and the actual character.

Both problems should be fixed by this patch.

Pat Pannuto e02866a1b4 Add missing headers to fix implicit function defns
A few files were missing headers for memset/malloc, likely missed
because the files don't directly call the functions, rather they
come in via macros in libc/include/sys/reent.h:

    #define _REENT_CHECK(var, what, type, size, init) do { \
      struct _reent *_r = (var); \
      if (_r->what == NULL) { \
        _r->what = (type)malloc(size); \

    #define _REENT_CHECK_ASCTIME_BUF(var) \
      _REENT_CHECK(var, _asctime_buf, char *, _REENT_ASCTIME_SIZE, \
        memset((var)->_asctime_buf, 0, _REENT_ASCTIME_SIZE))

Without these fixes, implicit function signatures are provided,
which gcc warns could cause aliasing issues down the line:

Corinna Vinschen 688d943a52 Always try to write complete incoming buffer on pipes and fifos
This patch fixes the following problem:

Commit 9636c426 refactored the pipe code especially to make sure
to call WriteFile only with chunks matching the maximum atomic write
count.  This accidentally introduced a small change in behaviour
on blocking pipes due to the success case falling through into the
error case.  Rather then writing atomic chunks until all bytes are
written, the code immediately broke from the loop after writing
the first chunk, basically the same as in case of non-blocking
writes.  This behaviour is not compliant to POSIX which requires

 "Write requests to a pipe or FIFO [...]

  * If the O_NONBLOCK flag is clear, a write request may cause the
    thread to block, but on normal completion it shall return nbyte."

Corinna Vinschen 6ed4753e77 rename: Refactor "new file already exists and rename fails" case
If newfile already exists and is in use, trying to overwrite it with
NtSetInformationFile(FileRenameInformation) fails exactly as if we
don't have the permissions to delete it.  Unfortunately the return code
is the same STATUS_ACCESS_DENIED, so we have no way to distinguish
these cases.  What we do here so far is to start a transaction to delete
newfile.  If this open fails with a transactional error we stop the
transaction and retry opening the file without transaction.

But, here's the problem: If newfile is in use, NtOpenFile(oldfile)
naturally does NOT fail with a transactional error.  Rather, the
subsequent call to unlink_nt(newfile) does, because there's another
handle open to newfile outside a transaction.  However, the code does
not check if unlink_nt fails with a transactional error and so fails
to retry without transaction.

This patch recifies the problem and checks unlink_nt's status as well.

Refactor code to get rid of goto into another code block.

Joe Seymour 83c39aedac Fix incorrect cast in nano malloc
As described in nano-mallocr.c, chunks of heap are represented in memory
as a size (of type long), followed by some optional padding containing a
negative offset to size, followed by the data area.

get_chunk_from_ptr is responsible for taking a pointer to the data area
(as returned by malloc) and finding the start of the chunk. It does this
by assuming there is no padding and trying to read the size, if the size
is negative then it uses that as an offset to find the true size.
Crucially, it reads the padding area as a long.

nano_malloc is responsible for populating the optional padding area. It
does so by casting a pointer to an (int *) and writing the negative
offset into it.

This means that padding is being written as an int but read as a long.

On msp430 an int is 2 bytes, while a long is 4 bytes. This means that 2
bytes are written to the padding, but 4 bytes are read from it: it has
only been partially initialised.

nano_malloc is the default malloc implementation for msp430.

This patch changes the cast from (int *) to (long *). The change to
nano_malloc has has been observed to fix a TI Energia project that
had been malfunctioning because malloc was returning invalid addresses.
The change to nano_memalign is based entirely on code inspection.

I've built and tested as follows:
  Configured (gcc+newlib) with: --target=msp430-elf --enable-languages=c
  gcc testsuite variations:
    msp430-sim/-mcpu=msp430
    msp430-sim/-mcpu=msp430x
    msp430-sim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either
    msp430-sim/-mhwmult=none
    msp430-sim/-mhwmult=f5series
My testing has shown no regressions, however I don't know if the gcc
testsuite provides sufficient coverage for this patch?

I don't have write access, so if this patch is acceptable after review,
I would appreciate it if someone would commit it for me.

startfiles of the build tree if available and not random ones from the
installation prefix for this procedure.  The search directories
specified by -B are a bit special, see for_each_path() in gcc.c of the
GCC sources.  First a search is performed on all search paths with the
multilib directory appended (if desired), then a second search is
performed on demand with the base directory only.  For each multilib
there is a "newlib" subdirectory.  This directory is specified by a -B
option for the support libraries.  In order to find the newlib artifacts
(ctr0.o, libc.a, libg.a and libm.a) they must be located in a proper
multilib subdirectory withing the build directory.
