2006-09-15  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am: Remove CRYPT_LIBS use; we no longer rely on libcrypt.
	* stdlib.c: Remove setkey(3) wrapper.
	* unistd.c: Remove encrypt(3) wrapper.

2006-08-13  Miguel de Icaza  <miguel@novell.com>

	* serial.c (get_bytes_in_buffer): Change the signature, we do not
	return any meaningful error other than -1.

2006-06-28  Zoltan Varga  <vargaz@gmail.com>

	* mph.h (MPH_INTERNAL): Only use this if HAVE_VISIBILITY_HIDDEN is
	defined since it is not supported on some archs with gcc.

2006-04-28  Wade Berrier <wberrier@novell.com>

	* serial.c: Add sys/filio.h for solaris for FIONREAD

2006-04-20  Geoff Norton  <gnorton@customerdna.com>

	* serial.c: Change TIOCINQ to FIONREAD to 
	fix the build on the *BSDs.

2006-04-19  Carlos Alberto Cortez <calberto.cortez@gmail.com>

	* serial.c: Added poll_serial () function, to poll
	outside the read_serial () functions; and get_bytes_in_buffer (), to
	get bytes in serialport buffers . Update some functions/enums
	used by System.IO.Port.SerialPort too (Changes aproved by Miguel:
	we will add tests in the managed side).
	
2006-03-22  Carlos Alberto Cortez <calberto.cortez@gmail.com>

	* serial.c: Add get_signal_code, get_signal, and set_signal
	functions to access serial signals. Also add a MonoSerialSignal
	enum, which is a copy of System.IO.Ports.SerialSignal.

Thu Mar 16 17:27:46 CET 2006 Paolo Molaro <lupus@ximian.com>

	* serial.c: removed useless serial.h file (it was also
	breaking the build).

2006-03-09  Carlos Alberto Cortez <calberto.cortez@gmail.com>

	* serial.c: Fix a pair of wrong or incomplete assignations
	in set_attributes.
	
2006-02-28  Carlos Alberto Cortez <calberto.cortez@gmail.com>

	* serial.h: New file with serial port constants.
	* serial.c: Use the constants in serial.h instead of magic numbers.
	
2006-01-03  Jonathan Pryor  <jonpryor@vt.edu>

	* sys-time.c: lutimes(2) only exists on some BSDs.  There's a configure
	  check for it now -- use it.

2005-12-28  Jonathan Pryor  <jonpryor@vt.edu>

	* map-icalls.h: Flush (add utimes_bad, lutimes, futimes).
	* sys-time.c: Add lutimes(2) and futimes(2) wrapper.

2005-12-27  Jonathan Pryor  <jonpryor@vt.edu>

	* map.c: Include <sys/mman.h>.  Fixes #77091.  Thanks to Ben Gamari.

2005-12-01  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am: Use $(CRYPT_LIB), not -lcrypt, as not all platforms 
	  support -lcrypt.
	* stdlib.c: Wrap Mono_Posix_Syscall_setkey() within HAVE_SETKEY, not
	  PLATFORM_WIN32

2005-12-01  Daniel Drake  <dsd@gentoo.org>

	* Makefile.am: Link against libcrypt, needed for setkey(3) as referenced
	in stdlib.c. Problem caught by Michael Hill.

2005-11-07  Jonathan Pryor  <jonpryor@vt.edu>

	* map-icalls.h: Oddly, this file didn't get the new functions added in
	  2005-10-14 -- ToConfstrName, FromConfstrName, etc.  Add them.
	* map.c, map.h: Remove invalid enumeration value SyslogFacility.LOG_USRE.

2005-10-14  Jonathan Pryor  <jonpryor@vt.edu>

	* signal.c: Don't build Syscall wrappers on Win32.

2005-10-14  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am (MPH_UNIX_SOURCE): Add syslog.c.
	* dirent.c, grp.c, pwd.c, signal.c, stdio.c, stdlib.c: Wrap functions which
	  return `void' so that they instead: (1) return `int', (2) clear errno
	  before calling the real function, and (3) return -1 if errno changed.
	  This must be done in native code because calling 
	  Stdlib.SetLastError/Syscall.xxx
	  from managed code won't work reliably (since errno may change between the
	  SetLastError call and the actual Syscall invocation).
	* unistd.c: Same as above, and allow fpathconf(3), pathconf(3), sysconf(3), 
	  and confstr(3) callers to explicitly choose their own errno value.
	* map.c, map.h: Handle enumeration name change in Mono.Unix.Native
	  (e.g. ConfStr --> ConfstrName, etc.).  This is so that they follow the
	  established naming conventions.
	* map-icalls.h: Add new icalls.
	* syslog.c: Added; wraps <syslog.h> functions.

2005-10-06  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am (MPH_C_SOURCE): Add string.c.
	* string.c: Added; exports strlen(3) wrapper.
	* map-icalls.h: Prototype for strlen(3) wrapper.

2005-09-29  Miguel de Icaza  <miguel@novell.com>

	* support-heap.c: Add meat to the Heap routines. 

2005-09-20  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am (refresh): Use the make-map.exe in Mono.Unix.Native.
	* map-icalls.h, map.c, map.h: Update to catch new enums AccessModes, Errno,  
	  and MmapProts.  Huge re-ordering because of namespace change in managed
	  code (not relevant to C API), and make-map.exe now outputs types/members
	  in alphabetical order (to avoid major code churn in the future).

2005-07-12  Daniel Drake  <dsd@gentoo.org>

	* sys-xattr.c: Use <attr/attr.h> if <sys/xattr.h> does not exist (e.g. for
	glibc 2.2)
	* Makefile.am: Link to libattr if libc does not provide the xattr
	syscalls.

Thu Jul 7 12:35:20 EDT 2005 Paolo Molaro <lupus@ximian.com>

	*supportw.c, Makefile.am: remove calls and link to libmono/libwapi.

2005-07-01  Daniel Drake  <dsd@gentoo.org>

	* sys-xattr.c: Support FreeBSD's extattr implementation. Slight API rework
	  to provide transparency between Linux and FreeBSD EA's.
	* map-icalls.h: Update as above

2005-06-30 Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* supportw.c: HeapDestroy.
	* Makefile.am: don't build supportw on windows.

2005-06-29  Ben Maurer  <bmaurer@ximian.com>

	* Makefile.am: namespace our library.

2005-06-29 Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* supportw.c:
	* supportw.h:
	* Makefile.am: new library intended to provide often P/Invoked windows
	API functions not present in io-layer.

2005-06-29  Jonathan Pryor  <jonpryor@vt.edu>

	* map.c: Handle Syslog-related changes (SyslogFacility isn't a 
	  [Flags] enum); make-map.exe changes.

2005-06-28  Jonathan Pryor  <jonpryor@vt.edu>

	* map.c, map.h: Handle Syslog-related changes (SyslogLevel isn't a [Flags]
	  enum; change in order between LOG_USER and LOG_USRE).

2005-06-27  Jonathan Pryor  <jonpryor@vt.edu>

	* map.c, map.h: Add corrected spelling of LOG_USER.

2005-06-13  Miguel de Icaza  <miguel@novell.com>

	*  sys-statvfs.c (copy_statfs): f_flags is the field name on BSD,
	not f_flag. 

2005-06-08  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am: Create an unversioned library.  We won't make any gaurantees
	  about ABI stability until Mono 1.2 (if then).

2005-06-07  Jonathan Pryor  <jonpryor@vt.edu>

	* sys-mman.c: Check for presence of mremap and remap_file_pages.

2005-06-05  Jonathan Pryor  <jonpryor@vt.edu>

	* map-icalls.h, map.h: Change header comment so it matches what 
	  `make refresh` generates.
	* map.c: Add <sys/xattr.h> header.

2005-05-31  Jonathan Pryor  <jonpryor@vt.edu>

	* sys-mman.c: Add wrappers for mmap, munmap, mprotect, msync, mlock,
	  munlock, mremap, mincore, remap_file_pages.
	* map-icalls.h: Update to latest shared interface.
	* map.c, map.h: Add {To,From} pairs for MmapFlags, MmapProt, MsyncFlags,
	  MlockallFlags, MremapFlags.
	* mph.h: Add mph_return_*_if_ssize_t_overflow macros.

2005-05-31  Jonathan Pryor  <jonpryor@vt.edu>

	* unistd.c: Oops -- deal with s/LockFlags/LockfCommand/ change.

2005-05-31  Jonathan Pryor  <jonpryor@vt.edu>

	* map.h, map.c, map-icalls.h: Rename LockFlags to LockfCommand.

2005-05-20  Zoltan Varga  <vargaz@freemail.hu>

	* Makefile.am (MPH_C_SOURCE): Add map-icalls.h. Fixes #75012.

2005-05-18  Jonathan Pryor  <jonpryor@vt.edu>

	* map-icalls.h: Added; auto-generated file which contains Mono_Posix_*
	  declarations for DllImport functions in Mono.Posix.dll.  This ensure
	  consistency between Mono.Posix.dll and MonoPosixHelper.so.
	* mph.h: Add include for map-icalls.h, to ensure that all MonoPosixHelper
	  exports have correct prototypes.
	* dirent.c, grp.c, macros.c, pwd.c, signal.c, stdio.c, sys-stat.c, 
	  sys-time.c, utime.c: Correct prototypes to match map-icalls.h.  Alas, this
	  "loses" information -- FILE* becomes void*, etc. -- but no semantics or
	  ABI should be changed (except for Mono_Posix_Syscall_utime).  Some
	  structure names also changed to match the generated names; since the
	  structures are private, this shouldn't break anything.
	* errno.c: Remove Mono_Posix_Syscall_SetLastError so we don't get a warning
	  about a missing prototype.  This was never in a stable release.
	* old-map.c: Include mph.h for prototype checking.
	* unistd.c: SeekFlags conversion is now done in managed code so that a short
	  isn't passed as a parameter; Correct prototypes to match map-icalls.h.
	* sys-xattr.c: fix lsetxattr/fsetxattr confusion; Correct prototypes to 
	  match map-icalls.h.
	* sys-sendfile.c: Move mph.h include so that HAVE_SYS_SENDFILE_H is used.
	* sys-wait.c: Include mph.h so that prototypes are checked.

2005-05-16  Jonathan Pryor  <jonpryor@vt.edu>

	* sys-statvfs.c: Include "map.h" for Mono_Posix_ToMountFlags prototype.
	* map.c: Include <sys/statvfs.h> so Mono_Posix_{To,From}MountFlags actually
	  does something useful.

2005-05-12  Jonathan Pryor  <jonpryor@vt.edu>

	* map.c, map.h: Add FromMountFlags, ToMountFlags.  (MountFlags is used in
	  `struct statvfs', which is POSIX).
	* sys-statvfs.c: Use ToMountFlags to convert the OS flags value into the
	  managed equivalent.

2005-05-03  Geoff Norton  <gnorton@customerdna.com>

	* sys-xattr.c:  Mac OS/X Tiger supports xattr but has a different API for supporting
	resource forks.  Allow mono to build on Tiger.

2005-04-30  Jonathan Pryor  <jonpryor@vt.edu>

	* stdio.c: Add Mono_Posix_Stdlib_DumpFilePosition, which create a hex string
	  "dump" of a fpos_t.  This is used for Mono.Unix.FilePosition.ToString().

2005-04-19  Jonathan Pryor  <jonpryor@vt.edu>

	* map.c, map.h: Added XattrFlags values, functions.
	* sys-xattr.c: Added; <sys/xattr.h> wrapper functions.  Thanks to Daniel
	  Drake for writing these.
	* Makefile.am: Add sys-xattr.c to the build.

2005-04-07  Jonathan Pryor  <jonpryor@vt.edu>

	* errno.c: Use the GNU version of strerror_r if _GNU_SOURCE is defined
	  (otherwise assume existence of XPG variant).  This allows proper
	  compilation under Red Hat 9.
	* fstab.c: protect against users calling setfsent(), setfsent(), ...  
	  endfsent(), which would otherwise leak a FILE handle.

2005-04-05  Zoltan Varga  <vargaz@freemail.hu>

	* mph.h: Apply patch from the freebsd ports collection.

2005-02-10  Zoltan Varga  <vargaz@freemail.hu>

	* zlib_macros.c (create_z_stream): Explicitly check for older versions
	of zlib.

2005-02-08  Zoltan Varga  <vargaz@freemail.hu>

	* pwd.c (Mono_Posix_Syscall_getpwnam_r): Add another part missing from the last patch.

2005-02-07  Jonathan Pryor  <jonpryor@vt.edu>

	* grp.c: Oops.  Didn't see other Solaris fix in #72292.

2005-02-07  Jonathan Pryor  <jonpryor@vt.edu>

	* grp.c, pwd.c: Clear errno before calling the actual calls, as errno may
	  have a stale value, leading to spurious errors later.  Fixes #72292.

2005-02-03  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am (MPH_C_SOURCE): Move errno.c into MPH_C_SOURCE, so it's built
	  on Windows as well as Unix.

2005-02-03  Jonathan Pryor  <jonpryor@vt.edu>

	* errno.c: Mono_Posix_Syscall_SetLastError should be in Stdlib, not Syscall, 
	  since it's part of ANSI C (and errno will be used from StdioFileStream).  
	  Add Mono_Posix_Stdlib_SetLastError.  Don't remove the Syscall version, as 
	  we don't want to break Mono 1.1.4/svn users the day after release. :-)

2005-01-25  Jonathan Pryor  <jonpryor@vt.edu>

	* macros.c: Use gint64, not long, to match C# declaration.  Fixes 71152.

2005-01-23  Geoff Norton  <gnorton@customerdna.com>

	* dirent.c: Include <unistd.h> to bring off_t in on gcc4.0+OSX

2005-01-13  Jonathan Pryor  <jonpryor@vt.edu>

	* map.h: Correct Mono_Posix_OpenFlags values (they should now match 
	  x86 linux); remove unused enumerations (MountFlags, etc.).

2005-01-13  Jonathan Pryor  <jonpryor@vt.edu>

	* fstab.c: Fix HPUX support.  HPUX includes both <fstab.h> and
	  <checkpoint.h>, so we need to give preference to <checkpoint.h>.

2005-01-05  Jonathan Pryor  <jonpryor@vt.edu>

	* fstab.c: Add support for HPUX, which uses <checklist.h>.

2005-01-05  Jonathan Pryor  <jonpryor@vt.edu>

	* map.c: Continuing my ineptitude...  <sys/wait.h> isn't on Win32.
	* mph.h: Win32 doesn't define EOVERFLOW, either.  Define it.

2005-01-05  Jonathan Pryor  <jonpryor@vt.edu>

	* map.c: Include <config.h> so we can check for PLATFORM_WIN32.

2005-01-05  Jonathan Pryor  <jonpryor@vt.edu>

	* map.c: Fix Win32 build break.  Win32 doesn't have all the sys/* headers.

2005-01-05  Jonathan Pryor  <jonpryor@vt.edu>

	* serial.c: HPUX compiler fix.
	* stdlib.c: Add C-defined macro wrappers.

2005-01-04  Jonathan Pryor  <jonpryor@vt.edu>

	* stdio.c: Add wrapper for C99's snprintf(3).

2005-01-04  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am: Rewrite.  Remove configure-generated warnings about 
	  multiple _LIBADD and _SOURCES lines.  Add support for Win32.  
	  Win32 support is limited to ANSI C functions.
	* stdio.c: Don't compile Unix wrappers on Win32.

2005-01-04  Raja R Harinath  <rharinath@novell.com>

	* Makefile.am (LIBS): Remove.  Was overriding results of configure check.
	(libMonoPosixHelper_la_LIBADD): List $(GLIB_LIBS) here.

2005-01-04  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am: Add libnsl to LIBS.  Hopefully this will let sparc link.
	* mph.h: Make MPH_INTERNAL conditional on __GNUC__.

2005-01-03  Jonathan Pryor  <jonpryor@vt.edu>

	* signal.c, stdio.c: Remove "function declaration isn't a prototype" warnings.
	* unistd.c: Check for presence of gethostname and sethostname.

2005-01-03  Jonathan Pryor  <jonpryor@vt.edu>

	* mph.h, x-struct-str.c: Add "const" to parameters to remove 
	  "warning: passing arg [2|4]...discards qualifiers" message.

2005-01-03  Jonathan Pryor  <jonpryor@vt.edu>

	* fstab.c: Remove some sparc compiler warnings.

2005-01-03  Jonathan Pryor  <jonpryor@vt.edu>

	* fstab.c: Solaris doesn't support getfsent(3), but it provides equivalent
	  functionality in getvfsent(3C).  Implement Solaris support.

2005-01-02  Jonathan Pryor  <jonpryor@vt.edu>

	* stdio.c: More wrapper functions.  I missed a few macros...  This should
	  complete all macro's defined in <stdio.h> for C99.

2004-12-30  Jonathan Pryor  <jonpryor@vt.edu>

	* stdio.c: More wrapper functions.  This should complete C89's <stdio.h>
	  requirements.

2004-12-30  Jonathan Pryor  <jonpryor@vt.edu>

	* sys-statvfs.c: Further proving that changing code without compiling is
	  dangerous business...  Compiler fix for OS X.

2004-12-30  Jonathan Pryor  <jonpryor@vt.edu>

	* signal.c: Mac OS X portability fixes -- it doesn't provide sighandler_t!

2004-12-30  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am: Add signal.c to the build.
	* signal.c: Added.  Contains helper functions to wrap signal(2).

2004-12-30  Jonathan Pryor  <jonpryor@vt.edu>

	* sys-statvfs.c: Fix Mac OS X build (statfs.f_frsize doesn't exist on OSX;
	  f_fsid isn't an integral type; fstatfs needs to use fpathconf).

2004-12-29  Jonathan Pryor  <jonpryor@vt.edu>

	* unistd.c: Null-terminate the string returned by readlink(2).  This works
	  around a marshaler "issue".

2004-12-28  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am: Add GLIB_LIBS to the LIBS line, since we require linking
	  against glib-2.0 (to use g_assert()).

2004-12-28  Jonathan Pryor  <jonpryor@vt.edu>

	* fstab.c: Added; wrap <fstab.h> functions: getfsent(3), getfsfile(3), 
	  getfsspec(3).
	* map.c: Add new conversion functions for SyslogOptions, SyslogFacility, 
	  SyslogLevel; see syslog(3) for details.
	* map.h: Add new conversion functions and values for SyslogOptions, 
	  SyslogFacility, SyslogLevel; see syslog(3) for details.
	* Makefile.am (MPH_SOURCE): add fstab.c, sys-statvfs.c, x-struct-str.c.
	* mph.h: Document location for Mac OS X man page documentation; add
	  MPH_INTERNAL macro for intra-library function calls (for functions that
	  shouldn't be exported from libMonoPosixHelper.so); declare
	  _mph_copy_structure_strings().
	* pwd.c: Use _mph_copy_structure_strings() to copy strings embedded within
	  struct passwd.
	* sys-statvfs.c: Added; wrap <sys/statvfs.h> functions statvfs(2),
	  fstatvfs(2), and (to complicate things) implement (f)statvfs(2) in terms
	  of (f)statfs(2) on Mac OS X (which lacks the -vfs calls).
	* x-struct-str.c: implements _mph_copy_structure_strings(), which is a
	  generalized interface to copy strings between structures (as is needed in
	  pwd.c and fstab.c).

Thu Dec 23 14:58:09 EST 2004 Paolo Molaro <lupus@ximian.com>

	* serial.c: remove mono calls from here: they break the build
	and they don't belong here.

2004-12-21  Chris Toshok  <toshok@ximian.com>

	* serial.c: initial import of System.IO.Ports pinvoke stuff.

	* Makefile.am (MPH_SOURCE): add serial.c.

2004-11-30  Jonathan Pryor  <jonpryor@vt.edu>

	* mph.h: Use <glib.h>, not <glib/gtypes.h>, as the HP/UX compiler needs
	  <glib/gutils.h> to handle the `inline' keyword.

2004-11-27  Miguel de Icaza  <miguel@ximian.com>

	* Makefile.am (MPH_SOURCE): Add macros.c for compatibility with
	the old API (currently the old API would fail).

2004-11-25  Raja R Harinath  <rharinath@novell.com>

	* Makefile.am (MPH_SOURCE): Distribute old-map.h and map.h.

2004-11-18  Jonathan Pryor  <jonpryor@vt.edu>

	* stdio.c: Add fread(3) and fwrite(3) wrappers.

2004-11-16  Jonathan Pryor  <jonpryor@vt.edu>

	* Makefile.am: Remove sys-mount.c from the build.
	* sys-mount.c: Delete.  We're not exporting mount-related functionality
	  anymore.  It's not remotely portable, and trying to make it portable is a
	  doomed idea.
	* map.c: Remove mount- and umount-related conversion functions.

2004-11-14  Geoff Norton  <gnorton@customerdna.com>
	
	* mph.h:  Revernt jonp's removal of MPH_ON_BSD define as sys-mount.c
	and unistd.c still check this configuration value.  This allows mono
	to build on *BSD again.

2004-11-12  Jonathan Pryor <jonpryor@vt.edu>

	* dirent.c: Only access members which exist on the target
	  platform.
	* errno.c: Only export strerror_r if it's available.
	* mph.h: Remove MPH_ON_BSD; use the configure checks instead.
	* sys-mman.c: Only export posix_madvise if it's available.
	* unistd.c: Only export sethostid if it's available.

2004-11-08  Jonathan Pryor <jonpryor@vt.edu>

	* Makefile.am: Add sys-sendfile.c to the build.
	* dirent.c, fcntl.c, unistd.c: Remove
	  compile-time checks for -64 apis (pread64, etc.), as they're
	  superfluous.  GLibc #defines the functions to the appropriate
	  -64 counterpart when necessary, and Darwin is intrinsically
	  large-file-aware, so manual checking on my part is redundant and
	  unnecessary.
	* grp.c: Add checks for non-portable functions getgrnam_r,
	  getgrgid_r.
	* pwd.c: Add checks for non-portable functions getpwnam_r,
	  getpwuid_r.
	* map.c: Remove <poll.h> include.  Building on Tiger (Mac
	  OS X 10.4 beta) breaks when both <poll.h> and <sys/poll.h> are
	  included, so only use <sys/poll.h>.
	* mph.h: Clean up macro handling for type overflow checking.

2004-11-05  Jonathan Pryor <jonpryor@vt.edu>

	* .cvsignore: Ignore generated files.
	* Makefile.am: Add new INCLUDE directives (for glib
	  headers), source; bump library version (so we don't clobber
	  previous versions of libMonoPosixHelper.so).
	* dirent.c: New file; <dirent.h> wrapper functions; 
	  BSD portability fixes.
	* errno.c: New file; <errno.h> wrapper functions
	* fcntl.c: New file; <fcntl.h> wrapper functions;
	  BSD portability fixes.
	* grp.c: New file; <grp.h> wrapper functions;
	  BSD portability fixes.
	* map.c: Updated macro mapping functions (more enums
	  mapped, more error checking, etc.).
	* map.h: Updated macro mapping functions
	* old-map.c: Previous map.c implementation, for backward
	  compatibility Remove spurious warning about redefining
	  _GNU_SOURCE.
	* old-map.h: Previous map.h implementation, for backward
	compatibility
	* mph.h: New file; Utility types, macros;
	  BSD portability fixes.
	* pwd.c: New file; <pwd.h> wrapper functions;
	  BSD portability fixes.
