- The internal handles in HPCON should not be inheritable, however,
the current code duplicates them as inheritable when handing over
ownership of the pseudo console. This patch fixes the issue.

* libc/include/machine/ieeefp.h (__FLOAT_TYPE, __DOUBLE_TYPE): New
macros.
* libc/include/math.h: Uses __DOUBLE_TYPE __FLOAT_TYPE to define
double_t float_t if possible.

- Currently, close_pseudoconsole() is called unconditionally from
fhandler_termios::process_sigs() on Ctrl-C. This causes deadlock
if Ctrl-C is pressed while setup_pseudoconsole() is called. With
this patch, close_pseudoconsole() is called only if the master
process is the owner of the nat-pipe to avoid the deadlock.

DEJAGNU could not find the function 'newlib_target_compile', because it was defined in another file.

This macro is unused or expands to nothing.

- As mentioned in commit message of the commit b531d6b0, if multiple
writers including non-cygwin app exist, the non-cygwin app cannot
detect pipe closure on the read side when the pipe is created by
system account or the the pipe creator is running as service.
This is because query_hdl which is held in write side also is a
read end of the pipe, so the pipe is still alive for the non-cygwin
app even after the reader is closed.
To avoid this problem, this patch lets all processes in the same
process group close query_hdl using newly introduced internal signal
__SIGNONCYGCHLD when non-cygwin app is started.

Removed the unused function _cleanup() from findfp.c.
|
|
This fixes a bug introduced in a previous patch (Commit 44b60f0c:
Make __sdidinit unused). Removed intitialization of __cleanup from
__smakebuf_r(). All callers of __smakebuf_r() call __sinit()
through the_CHECK_INIT macro, thus __cleanup is already
initialized. This fix also allows _cleanup_r() to be made static.
Changed its name to cleanup_stdio() and removed its declaration
from local.h.

[PATCH] newlib: Only call _fputwc_r if ELIX_LEVEL >= 4
(nano-)vfprintf.c is enabled for ELIX_LEVEL >= 1. When _WIDE_ORIENT
is set, its __sprint_r / __sfputs_r functions unconditionally called
_fputwc_r which is only in ELEX_LEVEL >= 4. With this commit,
the _WIDE support in (nano-)vfprintf.c is disabled for ELEX_LEVEL < 4.

This code has not been updated since 2016, and it looks like it has
rotted quite a bit since. It does not build against the current set
of phoenix sources -- I had to hack both the kernel headers and the
newlib headers up to get it to build, and I still have no idea if it
actually links or runs. It seems like the project itself has moved
away from newlib and to its own C library:
https://phoenix-rtos.com/documentation/libc/README.md
So since there's no interest from the phoenix folks to maintain this,
and it has a significant amount of non-standard code that we try to
keep up-to-date (without actually testing it), just punt it all.

The recent makefile reorganization broke the amdgcn port by creating
duplicate __malloc_lock symbols. This patch fixes the problem by renaming
the malloc_support.c file to mlock.c, thus overriding the default symbol
properly. Actually, I'm not sure how this ever worked?

Consistently use

I've had this lying around for probably a year or two at this point.
It just changes all the instance of "errno" from a common symbol to an
extern. I can't offhand recall where the actual definition is, but it
certainly exists in the generic code.

- Using memcmp() to compare structure such as INPUT_RECORD is not
correct manner because padding may not be initialized. This patch
stops to use memcmp() for comparison of INPUT_RECORD.
|
|
- dwControlKeyState also may be null'ed on WriteConsoleInputW().
Therefore ignore it in event comparison as well as wVirtualKeyCode
and wVirtualScanCode.
|
|
|
|
- The commit "Cygwin: console: Improve the code to avoid typeahead
key swapping." did not solve the problem enough. Two unexpected
things happen.
(1) wVirtualKeyCode and wVirtualScanCode of readback key event may
be null'ed even if they are not zero on WriteConsoleInputW().
Therefore, memcmp() may report the event sequence is not equal.
(2) WriteConsoleInputW() may not be atomic. The event sequence
which is written by WriteConsoleInputW() may be inserted by
key input in the middle of the sequence. Current code gives
up to fix in this situation.
This patch should fix that issue.

This was disabled as part of the migration away from the cygnus option
as that implied no-dependencies.
We currently have 1-to-1 updates enabled -- if you touch a .c file,
the corresponding .o file will be rebuilt. But if you touch a header
file, none of the files using that get rebuilt.

When using a compiler that automatically enables -D_FORTIFY_SOURCE,
building winsup fails with errors like below. Since winsup is not
setup to compile itself with _FORTIFY_SOURCE, disable it for now.

Integrate the old libm/test/ subdir into the main build. It hasn't
been used in a long time causing the code to rot a bit. I've fixed
some of those, but it still fails for many ports, so it's disabled
by default. People who want to take a closer look can run:
$ make libm/test/test
|
|
To help prevent people from missing running this script, integrate it
into the build via maintainer mode.
Also fix the inverted exit status to make this work correctly -- for
some reason, it exited 1 when it worked, and 0 when it failed.
|
|
Replace all of the individual autotool steps with a single autoreconf.
This simplifies the documentation greatly, and in the current system,
only takes ~10 seconds to regenerate everything.
Update the developer documentation to cover all the major components
of the current build system. Hopefully this is a fairly complete road
map to everything. I tried to include everything that I wish I knew
when I started hacking on this :P.

Convert all the libc/ subdir makes into the top-level Makefile. This
allows us to build all of libc from the top Makefile without using any
recursive make calls. This is faster and avoids the funky lib.a logic
where we unpack subdir archives to repack into a single libc.a. The
machine override logic is maintained though by way of Makefile include
ordering, and source file accumulation in libc_a_SOURCES.
There's a few dummy.c files that are no longer necessary since we aren't
doing the lib.a accumulating, so punt them.
The winsup code has been pulling the internal newlib ssp library out,
but that doesn't exist anymore, so change that to pull the objects.

- Variable remlen stores the return value of QueryDosDeviceW(), so
it is better to be DWORD.
|
|
- If UNC path for DFS is mounted to a drive with drive letter, the
error "Too many levels of symbolic links" occurs when accessing
to that drive. This is because GetDosDeviceW() returns unexpected
string such as "\Device\Mup\DfsClient\;Z:000000000003fb89\dfsserver
\dfs\linkname" for the mounted UNC path "\??\UNC\fileserver\share".
This patch adds a workaround for this issue.

- Unlike linux, fsync() calls FlushFileBuffers() even for special

Rather than define per-object rules in the Makefile, have small files
that define & include the right content. This simplifies the build
rules, and makes understanding the source a little easier (imo) as it
makes all the subdirs behave the same: you have 1 source file and it
produces 1 object. It's also about the same amount of boiler plate,
without having to define custom build rules that can fall out of sync.
We also realign the free & pvalloc definitions: common code puts these
in malloc.o & valloc.o respectively, not in free.o & pvalloc.o objects.
This will also be important as we merge the libc.a build into the top
dir since it relies on a single flat list of objects for overrides.
|
|
Move the multiplex logic out of the build and into source files to
make the build rules a lot simpler.
|
|
The mallopt symbol is defined in tiny-malloc.c, not mallocr.c, but
the Makefile in here tries to compile it out of the latter. This
leads to mallopt never being defined.
The build also creates mallinfo.o & mallopt.o & mallstats.o objects
to override common ones, but the common dir doesn't use these names.
Instead, it places these all in mstats.o.
So move the build define logic to a dedicated file and compile it
directly to make things a bit simpler while fixing the missing func
and aligning objects with the cmomon code.

- After the commit "Cygwin: pty, console: Fix handle leak which
occurs on exec() error.", startxwin cannot start X due to the
error "Failed to activate virtual core keyboard: 2". The problem
is access violation in the code retrieving the pgid of the ctty.
This patch fixes the issue.

Also take the opportunity to clean up the unnecessary header deps in

Some awk implementations such as old versions of mawk do not support the
length() function. Use the return value of the POSIX split() function instead.

This file is a little confusing: it provides all of the mallocr logic,
but is compiled multiple times to produce a unique symbol each time.
For example, building mallocr.c with -DDEFINE_FREER produces freer.o
that only defines _free_r(). This is fine for most symbols, but it's
a little confusing when defining mallocr itself -- we produce a file
with the same symbol name, but we still need -DDEFINE_MALLOCR. In
order to move the logic from the build rules to source files, using
mallocr.c both as a multiplexer and for defining a single symbol is a
bit tricky. It's possible (if we add a lot of redundant preprocessor
checks to mallocr.c, or we add complicated build flags just for this
one files), but it's easier if we simply rename this to a dedicated
file. So let's do that.
We do this as a dedicated commit because the next one will create a
new mallocr.c file and git's automatic diff algorithms can handle
trivial renames, but it can't handle renames+creates in the same
commit.
|
|
Simplify the build system logic a bit by moving the mallocr.c ->
nano-mallocr.c redirection from the Makefile to the source files.
This allows for consistent object name usage regardless of the
configuration options used in case a machine dir wants to define
its own override.
