The upper 16 bits - are used for special cygwin operations. - * winsup.h: Change definition of do_exit to allow calling from - signal handler. - * dcrt0.cc (do_exit): Change to allow calling from signal handler - in place of _exit. This is necessary to ensure that only cygwin - internal applications can exit with the upper order 16 bits set - to non-zero. - -Wed Nov 12 23:02:34 1997 Geoffrey Noer <noer@cygnus.com> - - patch from cgf@bbc.com (Chris Faylor): - * dcrt0.cc (do_exit): New function. Subsumes functionality of - _exit but takes a DWORD argument. Changed to avoid some shutdown - activities when called with REPARENTING bit set in argument. Also - explicitly kills any executing non-cygwin subprocess from a - spawn(P_OVERLAY)... - (_exit): Use do_exit for exiting. Ensure that only low order 1 - bits of status are used or confusion will result if exiting with - some higher order bits set. - * exceptions.cc (set_process_mask): Reflect new method for - sig_send to send signals to self. - (handle_sigsuspend): Reflect new method for sig_send to send - signals to self. - * fork.cc: A handle name was changed in the pinfo structure to - be more reflective of its use. Change forkee_stopped to - subproc_ready everywhere. - * pinfo.cc (pinfo::clearout): Change forkee_stopped to - subproc_ready. - (pinfo_init): Use PID_EXECED flag to determine if this process has - been execed. If so, signal the remaining stub in the process - which invoked us so that the stub can terminate and let us take - over as this pid. - * sigproc.cc (sig_send): Change method for determining if sending - signals to myself. A NULL pointer means communicate with my - signal handler. This is necessary to allow communication with - our own signal processors after reparenting an execed process. - Also, add an additional test to detect if a process goes away in - the middle of attempting to send it a signal. - (allow_sig_dispatch): Reflect new method for sig_send to send - signals to self. - (getsem): Use dwProcessId in names for signal semaphores. Allows - communicating with both parts of a process that is temporarily - "split in two" while execing. - (sig_proc): Avoid printing an error if WAIT_FAILED and exiting - anyway. Process requests even if loop_wait == 0. - (proc_subproc): Defensive check for manipulating processes prior - to initialization or after terminating sigproc. - Use different check for subprocesses that have been reparented. - Hopefully this will eliminate WFSO, error 6 problems. - (wait_subproc): Only exit when loop_wait == 0 and not dealing with - a process. - * spawn.cc: Set up two global variables, used on exit when - execing a non-cygwin process: hExeced - handle of non-cygwin - process which is being waited for by a stub, pExeced - windows pid - of the process. - (spawn_guts): Reorganize to always (temporarily) wait for the new - process when P_OVERLAY. If a cygwin process is invoked, then the - wait will return when an event is signalled and the new process - will be "reparented" in the ppid. If a non-cygwin process is - invoked, wait until the process exits or a signal is received - which terminates the process.

This is where the unix device -emulation happens. - -dtable.cc maps posix file descriptors to a table of file handlers (type -fhandler) in the dll. It's mostly concerned with managing the table -of descriptors (open, dup, fork, select). Most of the posix I/O -system calls (syscalls.cc) use the fdtab table to call the right -fhandler directly. - -fhandler.cc is the base class; specific types are derived as -appropriate (see fhandler.h). dtable.cc is in charge of selecting and -creating a suitable fhandler when you open a file. path.cc handles -emulated files in /dev (like /dev/null) by returning an FH_* value -from get_device_number (which dtable.cc calls in dtable::build_fhandler). - -Note: if you're looking for read() and write(), they call _read() and -_write() in syscalls.cc. The non-underscored ones are in -newlib/libc/syscalls and just call the underscored ones. - -=== How "fork" works - -It all starts in fork() in fork.cc. - -Set up a pid in the shared memory area for the new child. Use -setjmp() to capture state. First time (parent), set up some stuff and -use CreateProcess to run a second copy of the same executable. The -second copy will note in the shared memory area that it's a fork, and -do the longjmp. They sync up and the parent copies all it's program -memory to the child's address space. There's also code to reload -dlls, map shared memory and mmap'd files, etc. - -Handling the special startup for the child is done in dcrt0.cc in many -places. This case is triggered by a special StartupInfo structure -that's passed from the parent to the child in CreateProcessA. diff --git a/winsup/cygwin/acconfig.h b/winsup/cygwin/acconfig.h deleted file mode 100644 index c187c0be3..000000000 --- a/winsup/cygwin/acconfig.h +++ /dev/null @@ -1,14 +0,0 @@ -/* Define if DEBUGGING support is requested. */ -#undef DEBUGGING - -/* Define if building "extra" thread-safe Cygwin DLL. */ -#undef _CYG_THREAD_FAILSAFE - -/* Define if GCC supports builtin memset. */ -#undef HAVE_BUILTIN_MEMSET - -/* Define if building thread-safe Cygwin DLL. */ -#undef _MT_SAFE - -/* Define if using new vfork functionality. */ -#undef NEWVFORK diff --git a/winsup/cygwin/ansi.sgml b/winsup/cygwin/ansi.sgml deleted file mode 100644 index d6a41ab31..000000000 --- a/winsup/cygwin/ansi.sgml +++ /dev/null @@ -1,59 +0,0 @@ -<sect1 id="std-ansi"> -<title>Compatibility with ANSI</title> - -<para>The following functions are compatible with ANSI:</para> - -<sect2><title>stdio</title><para> - -clearerr, fclose, feof, ferror, fflush, fgetc, fgetpos, fgets, fopen, -fprintf, fputc, fputs, fread, freopen, fscanf, fseek, fsetpos, ftell, -fwrite, getc, getchar, gets, perror, printf, putc, putchar, puts, -remove, rename, rewind, scanf, setbuf, setvbuf, sprintf, sscanf, -tmpfile, tmpnam, vfprintf, ungetc, vprintf, vsprintf, - -</para></sect2> -<sect2><title>string</title><para> - -memchr, memcmp, memcpy, memmove, memset, strcat, strchr, strcmp, -strcoll, strcpy, strcspn, strerror, strlen, strncat, strncmp, strncpy, -strpbrk, strrchr, strspn, strstr, strtok, strxfrm - -</para></sect2> -<sect2><title>stdlib</title><para> - -abort, abs, assert, atexit, atof, atoi, atol, bsearch, calloc, div, -exit, free, getenv, labs, ldiv, longjmp, malloc, mblen, mbstowcs, -mbtowc, qsort, rand, realloc, setjmp, srand, strtod, strtol, strtoul, -system, wcstombs, wctomb - -</para></sect2> -<sect2><title>time</title><para> - -asctime, gmtime, localtime, time, clock, ctime, difftime, mktime, -strftime - -</para></sect2> -<sect2><title>signals</title><para> - -raise, signal - -</para></sect2> -<sect2><title>ctype</title><para> - -isalnum, isalpha, iscntrl, isdigit, isgraph, islower, isprint, -ispunct, isspace, isupper, isxdigit, tolower, toupper - -</para></sect2> -<sect2><title>math</title><para> - -acos, asin, atan, atan2, ceil, cos, cosh, exp, fabs, floor, fmod, -frexp, ldexp, log, log10, modf, pow, sin, sinh, sqrt, tan, tanh - -</para></sect2> -<sect2><title>misc</title><para> - -localeconv, setlocale, va_arg, va_end, va_start - -</para></sect2> - -</sect1>

Let's start with how versioning used to be done. - - Historical versioning in Cygwin 16.0 to 19.5: - - In the olden days of Cygwin, we had a dll major and minor version - and a registry version. The major number started at 16 because the - "b15" GNU-Win32 release of the compiler tools was out when this - scheme was started. We incremented the DLL name frequently (for - every official release) and towards the end of this period every - release used a different shared memory area to prevent DLLs from - interfering with each other (embedding a build timestamp into the - name of the shared memory area). This turned out to be a Bad Idea - (tm) because people needed to mingle separate releases and have - them work together more than we thought they would. This was - especially problematic when tty info needed to be retained when an - old Cygwin executable executed a newer one. - - In the old scheme, we incremented the major number whenever a - change to the dll invalidated existing executables. This can - happen for a number of reasons, including when functions are - removed from the export list of the dll.

If a handler does not want to handle -the exception it should just return ExceptionContinueSearch, which is 1. - -The handler has the following parameters: -ehandler ( - PEXCEPTION_RECORD erecord, - PEXCEPTION_FRAME myframe, - PCONTEXT context, /-* context before and after *-/ - PVOID dispatch) /-* something *-/ - -When a handler wants to handle the exception, it has some alternatives: - --one is to do do something about the exception condition, like emulating -an invalid instruction, mapping memory where there was a page fault, etc. -If the handler wants to have the context of the thread that causes the -exception changed, it should make that change in the context passed to the -handler. - --the second alternative is to call all exception handlers again, indicating -that you want them to clean up.

This might - * be used for mail addresses or remote logins. - * EX_NOHOST -- The host specified did not exist. This is used - * in mail addresses or network requests. - * EX_UNAVAILABLE -- A service is unavailable. This can occur - * if a support program or file does not exist. This - * can also be used as a catchall message when something - * you wanted to do doesn't work, but you don't know - * why. - * EX_SOFTWARE -- An internal software error has been detected. - * This should be limited to non-operating system related - * errors as possible. - * EX_OSERR -- An operating system error has been detected. - * This is intended to be used for such things as "cannot - * fork", "cannot create pipe", or the like. It includes - * things like getuid returning a user that does not - * exist in the passwd file. - * EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, - * etc.) does not exist, cannot be opened, or has some - * sort of error (e.g., syntax error). - * EX_CANTCREAT -- A (user specified) output file cannot be - * created. - * EX_IOERR -- An error occurred while doing I/O on some file. - * EX_TEMPFAIL -- temporary failure, indicating something that - * is not really an error. In sendmail, this means - * that a mailer (e.g.) could not create a connection, - * and the request should be reattempted later. - * EX_PROTOCOL -- the remote system returned something that - * was "not possible" during a protocol exchange. - * EX_NOPERM -- You did not have sufficient permission to - * perform the operation. This is not intended for - * file system problems, which should use NOINPUT or - * CANTCREAT, but rather for higher level permissions. - */ - -#define EX_OK 0 /* successful termination */ - -#define EX__BASE 64 /* base value for error messages */ - -#define EX_USAGE 64 /* command line usage error */ -#define EX_DATAERR 65 /* data format error */ -#define EX_NOINPUT 66 /* cannot open input */ -#define EX_NOUSER 67 /* addressee unknown */ -#define EX_NOHOST 68 /* host name unknown */ -#define EX_UNAVAILABLE 69 /* service unavailable */ -#define EX_SOFTWARE 70 /* internal software error */ -#define EX_OSERR 71 /* system error (e.g., can't fork) */ -#define EX_OSFILE 72 /* critical OS file missing */ -#define EX_CANTCREAT 73 /* can't create (user) output file */ -#define EX_IOERR 74 /* input/output error */ -#define EX_TEMPFAIL 75 /* temp failure; user is invited to retry */ -#define EX_PROTOCOL 76 /* remote error in protocol */ -#define EX_NOPERM 77 /* permission denied */ -#define EX_CONFIG 78 /* configuration error */ - -#define EX__MAX 78 /* maximum listed value */ - -#endif /* !_SYSEXITS_H_ */ diff --git a/winsup/cygwin/include/syslog.h b/winsup/cygwin/include/syslog.h deleted file mode 100644 index 5721ca5e4..000000000 --- a/winsup/cygwin/include/syslog.h +++ /dev/null @@ -1,16 +0,0 @@ -/* syslog.h - - Copyright 1996, 1998, 2001 Red Hat, Inc. - -This file is part of Cygwin. - -This software is a copyrighted work licensed under the terms of the -Cygwin license.

In general, -if you want blazing speed you're in the wrong place.

There are no "reserved" char values except for -NUL, and no special significance is attached to the top bit of chars. -The string(3) functions are used a fair bit, on the grounds that they are -probably faster than coding the operations in line.
