Cygwin: add 3.2.1 release file and add fixes up to this point Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2021-04-20 16:46:01 +08:00
What's new:
-----------
Cygwin: updates to wire in profiler, gmondump These are updates to wire into the build tree the new tools profiler and gmondump, and to supply documentation for the tools. The documentation for profiler and ssp now mention each other but do not discuss their similarities or differences. That will be handled in a future update to the "Profiling Cygwin Programs" section of the Cygwin User's Guide, to be supplied.
2021-07-16 12:49:57 +08:00
- An IP-sampling profiler named 'profiler' has been added. It can be used
to profile any Cygwin program along with any DLLs loaded.
- A new tool 'gmondump' has been added. It can dump the raw information
of any "gmon.out" file created by profiler, ssp, or use of the gcc/g++
option '-pg'. (Continue using gprof to get symbolic profile displays.)
Cygwin: clarify importance of new GNU-specifc API Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2021-08-02 19:53:38 +08:00
- New GNU-specific APIs, slated to become part of the next POSIX standard:
pthread_cond_clockwait, pthread_mutex_clocklock, pthread_rwlock_clockrdlock,
pthread_rwlock_clockwrlock, sem_clockwait.

What changed:
-------------
Cygwin: cfsetspeed: allow speed to be a numerical baud rate The Linux man page for cfsetspeed(3) specifies that the speed argument must be one of the constants Bnnn (e.g., B9600) defined in termios.h. But Linux in fact allows the speed to be the numerical baud rate (e.g., 9600). For consistency with Linux, we now do the same. Addresses: https://cygwin.com/pipermail/cygwin/2021-July/248887.html
2021-07-11 19:04:58 +08:00
- The speed argument to cfsetspeed(3) can now be a numerical baud rate
rather than a Bnnn constant, as on Linux.

Bug Fixes
---------
- Fix values returned by select(2) for shutdown sockets.
Addresses: https://cygwin.com/pipermail/cygwin-developers/2021-April/012092.html
Cygwin: connect: set connect state for DGRAM sockets When connect is called on a DGRAM socket, the call to Winsock's connect can immediately return successfully rather than failing with WSAEWOULDBLOCK. Set the connect state to "connected" in this case. Previously the connect state remained "connect_pending" after the successful connection.
2021-04-24 02:40:07 +08:00
- Introduce a new hypotl(3) function not suffering unnecessary overflows.

2021-04-24 02:40:07 +08:00
- Fix a bug in recognizing a successful completion of connect(2) on a
datagram socket.
Cygwin: connect: implement resetting a connected DGRAM socket Following POSIX and Linux, allow a connected DGRAM socket's connection to be reset (so that the socket becomes unconnected). This is done by calling connect and specifing an address whose family is AF_UNSPEC.
2021-04-24 06:17:57 +08:00
- Fix connect(2) when called with an address structure whose family is
AF_UNSPEC. As specified by POSIX and Linux, this is allowed on
datagram sockets, and its effect is to reset the socket's peer
address.
Ensure nanosleep(2) never returns negative rem It appears to be the case that NtQueryTimer can return a negative time remaining for an unsignalled timer. The value appears to be less than the timer resolution. Signed-off-by: David Allsopp <david.allsopp@metastack.com>

Cygwin: fix all usages of NtQueryDirectoryObject Due to reports on the Cygwin mailing list[1][2], it was uncovered that a NtOpenDirectoryObject/NtQueryDirectoryObject/NtClose sequence with NtQueryDirectoryObject iterating over the directory entries, one entry per invocation, is not running atomically. If new entries are inserted into the queried directory, other entries may be moved around and then accidentally show up twice while iterating. Change (almost) all NtQueryDirectoryObject invocations so that it gets a really big buffer (64K) and ideally fetches all entries at once. This appears to work atomically. "Almost" all, because fhandler_procsys::readdir can't be easily changed.

Cygwin: Make native clipboard layout same for 32- and 64-bit 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.
2021-10-25 17:25:40 +08:00
- Fix access violation that can sometimes occur when copy/pasting between
32-bit and 64-bit Cygwin environments. Align clipboard descriptor layouts.

Cygwin: convert malloc lock to SRWLOCK 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. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

- Fix a synchronization issue when running multiple threads from DLL
initialization which in turn call malloc.
