* Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen2016-06-231-2/+0
| | | | | | | | | | | | | | Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause. Everything else stays under GPLv3+. New Linking Exception exempts resulting executables from LGPLv3 section 4. Add CONTRIBUTORS file to keep track of licensing. Remove 'Copyright Red Hat Inc' comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Revert "Refactor to avoid nonnull checks on "this" pointer."Corinna Vinschen2016-04-051-40/+15
| | | | | | | | | This reverts commit 0008bdea02b690ab19ffe997499cb9a96ee5a66d. This patch introduced a regression. Calling FOO=$(...) in zsh hangs indefinitely and has to be killed forcefully. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

(chown_worker): Detect if this is an 'auto' device rather than an on-filesystem device and handle appropriately. (chmod_device): New function. (chmod): Detect if this is an 'auto' device rather than an on-filesystem device and handle appropriately. Use chmod_device to set mode of in-filesystem devices. (stat_worker): Eliminate path_conv argument. Call build_fh_name to construct fhandler. Use fh->error() rather than pc->error to detect errors in fhandler construction. (access_worker): New function pulled from access. Accommodate in-filesystem devices. (access): Use access_worker. (fpathconf): Detect if this is an 'auto' device rather than an on-filesystem device and handle appropriately. (mknod_worker): New function. (mknod32): New function. (chroot): Free normalized path -- assuming it was actually cmalloced. * tty.cc (create_tty_master): Tweak for new device class. (tty::common_init): Ditto. * winsup.h (stat_worker): Remove. (symlink_worker): Declare. * exceptions.cc (set_process_mask): Just call sig_dispatch_pending and don't worry about pending_signals since sig_dispatch_pending should always do the right thing now. (sig_handle): Reorganize SIGCONT handling to more closely conform to SUSv3. * pinfo.h: Move __SIG enum to sigproc.h. (PICOM_FIFO): New enum element. (_pinfo): Remove 'thread2signal' stuff throughout class. (_pinfo::commune_send): Make varargs. (_pinfo::sigtodo): Eliminate. (_pinfo::thread2signal): Ditto. * signal.cc (kill_worker): Eliminate call to setthread2signal. * sigproc.cc (local_sigtodo): Eliminate. (getlocal_sigtodo): Ditto. (sigelem): New class. (pending_signals): New class. (sigqueue): New variable, start of sigqueue linked list. (sigcatch_nonmain): Eliminate. (sigcatch_main): Eliminate. (sigcatch_nosync): Eliminate. (sigcomplete_nonmain): Eliminate. (pending_signals): Eliminate. (sig_clear): Call signal thread to clear pending signals, unless already in signal thread. (sigpending): Call signal thread to get pending signals. (sig_dispatch_pending): Eliminate use of pending_signals and just check sigqueue. (sigproc_terminate): Eliminate all of the obsolete semaphore stuff. Close signal pipe handle. (sig_send): Eliminate all of the obsolete semaphore stuff and use pipe to send signals. (getevent): Eliminate. (pending_signals::add): New function. (pending_signals::del): New function. (pending_signals::next): New function. (wait_sig): Eliminate all of the obsolete semaphore stuff. Use pipe to communicate and maintain a linked list of signals. * sigproc.h: Move __SIG defines here. Add __SIGPENDING. (sig_dispatch_pending): Remove "C" specifier. (sig_handle): Accept a mask argument. * thread.cc: Remove signal handling considerations throughout.
* Throughout, remove "include <errno.h>" from files which already includeChristopher Faylor2003-06-161-1/+0
| | | | | | | | | | | | | | | | | | | cygerrno.h. * include/cygwin/config.h (__DYNAMIC_REENT__): Define. * include/cygwin/version.h: Bump API minor version. * cygwin.din: Export __getreent * cygerrno.h: Include errno.h. Fix places where _impure_ptr is used directly to store the errno value. * debug.cc (__set_errno): Ditto. * errno.cc: Remove _RRENT_ONLY define to get errno.cc compiled. * signal.cc: Rename _reent_clib to _REENT throughout. * thread.h (reent_clib): Remove prototype. * thread.cc (reent_clib): Rename reent_clib to __getreent. Return _impure_ptr until MTinterface is initialized. (reent_winsup): Fix a possible SEGV when _r == NULL. Return NULL instead. * MTinterface::fixup_after_fork: Switch reent back to _impure_ptr to keep signal handling running when fork is called from a thread other than the mainthread.
* * dir.cc: Change __off32_t to _off_t and __off64_t to _off64_tCorinna Vinschen2003-04-011-2/+2
