早期freebsd实现

Wed Dec  9 14:48:38 1992  Per Bothner  ([e-mail])

	* streambuf.h:  #undef open and close, in case some header
	file defines these as macros.

Thu Dec  3 19:40:07 1992  Per Bothner  ([e-mail])

	* Makefile.in (distclean, realclean): Don't delete
	Makefile until *after* recursing.

Mon Nov 23 14:05:47 1992  Per Bothner  (bothner at cygnus.com)

	* filebuf.C (filebuf::open):  Fix typo ios::app -> ios::out.

Tue Nov 17 21:52:55 1992  Per Bothner  ([e-mail])

	* filebuf.C (filebuf::open):  ios::app implies ios::out.
	* igetline.C (istream::getline, istream::get):  Slightly more
	complicated to handle empty lines without setting error state.

Thu Nov  5 18:08:48 1992  Per Bothner  ([e-mail])

	* streambuf.h:  Add _S_IS_APPENDING flag.
	* filebuf.C:  Handle append mode better.  (Seek to end when
	opening. File position is unpredictable before and after a write.)
	* streambuf.h:  Fix semi-typo for value of ios:fixed.

Mon Nov  2 22:25:53 1992  Per Bothner  ([e-mail])

	* strstream.h (strstream):  Fix broken default constructor.
	* stdstrbufs.C:  Don't include unneeded <stdiostream.h>
	(which caused mips assembler to complain about a conflict).
	* stdiostream.C (stdiobuf::sync):  Don't call fflush()
	on read-only files.

Sun Nov  1 14:54:26 1992  Per Bothner  ([e-mail])

	* floatconv.C:  Renamed from dtoa.C, to avoid conflicts
	with ../src/dtoa.cc.
	* Makefile.in:  Update as appropriate.

	* filebuf.C, indstream.{h,C}, stdiostream.{h,C}, streambuf.{h,C}:
	Rename sputn/sgetn virtual methods to xsputn/xsgetn.
	Add sputn/sgetn inlined non-virtual that just call  xsputn/xsgetn.
	This change is to be compatible with ANSI and AT&T.
	* stdstrbufs.C:  Make sure all standard stdiobufs are unbuffered.

Wed Oct 21 17:48:03 1992  Per Bothner  (bothner at PersSony)

	* outfloat.C (__outfloat): If no error, return value is
	number of characters printed.
	* sbufvform.C (streambuf::vform):  Fix a number of buglets.

Tue Oct 20 15:20:17 1992  Per Bothner  ([e-mail])

	* streambuf.h, sbufvscan.C, sbufvform.C : Add streambuf::scan
	and streambuf::form.
	* sbufvform.C:  Fix handling of precision for integer formats.
	* iostream.texi: Document the various form & scan methods.

Fri Oct 16 15:42:15 1992  Per Bothner  ([e-mail])

	Many changes here and there, many to bring closer to ANSI draft.

	* streambuf.h:  Fill character is now wchar_t.
	Add some (unused) hooks for raising exceptions.
	* sbufvscan.C (streambuf::vscan):  Set error state using an
	to (ios*) parameter instead of an (ios::iostate*).
	* iostream.C:  Change usages of streambuf::vscan().
	* iostream.C:  Slightly changed interpretations of basefield.
	* iostream.h:  Add some missing methods (signed and
	unsigned char versions of put(), get(), and getline()).
	* streambuf.{ch], indstream.[Ch]:  Removed ungetfail virtual,
	following latest ANSI draft:  Use pbackfail virtual instead.
	* filebuf.C: Moved streambuf::_un_link and streambuf::_link_in
	to streambuf.C.
	* filebuf.C (filebuf::attach):  Do *not* set _S_DELETE_DONT_CLOSE
	flag, for compatibily with AT&T.
	* filebuf.C (filebuf::seekoff):  Don't move any pointers
	if mode is 0.
	* fstream.h:  Add fstreambase::setbuf() and fstreambase::is_open().
	* fstream.[Ch] (fstreambase::close):  Set failbit if close fails.
	* fstream.C (fstreambase constructors), strstream.C (various
	constructors):  Use new ios::init() method.
	* fstream.C (fstreambase::open):  Do a clear() first.

	* strstream.[hC]:  Add strsteambuf constructors with (const char*)
	buffer.  These call new method init_const(), which sets the
	_NO_WRITE flag.  New strstreambuf::pbackfail() method fails
	if _NO_WRITE flag is set.  Needed for ANSI.
	* strstream.[hC]:  Add support for user-supplied allocation
	and free routines (from ANSI).  (New methods init_static
	and init_dynamic now used by constructors.)
	* strstream.C (strstreambuf::init_static):  Try new mechanism
	for when the buffer is "assumed to continue indefinitely."

	* iostream.C, stdstrbufs.C:  Remove not_open_filebuf.
	* stdstrbufs.C: Rename _{cin,cout,cerr}_sbuf to
	__std_filebuf_{0,1,2}.  Also define __std{in,out,err}_stdiobuf
	as standard stdiobufs.  Chain all 6 standard streambufs together.
	* stdstreams.C:  Use the __std{in,out,err}_stdiobuf rather
	than __std_filebuf_{0,1,2} by default for {cin,cout,cerr}
	- unless _STDIO_USES_IOSTREAM or USE_FILEBUF are defined.
	* streambuf.h, stdstreams.C:  New function ios::sync_with_stdio
	to switch between using __std_filebuf_{0,1,2} and
	__std{in,out,err}_stdiobuf for standard streams.  This is
	normally not needed, but is provided for AT&T compatibility.

	* iomanip.h: Rename template classes to be lower-case (following
	ANSI).  Don't declare anything if _G_NO_TEMPLATES is defined in
	<_G_config.h>.  Rename DEFINE_IOMANIP_FN1 -> __DEFINE_IOMANIP_FN1.

	* stdiostream.[hC]:  Re-implement:  Make stdiobuf sub-class
	of filebuf, and use the virtual sys_ functions (e.g. sys_read)
	to call stdio function (e.g. fread).  This simpifies stdiobuf,
	and gives us filebuf features automatically.

Sun Oct 11 19:12:20 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

	* Makefile.in: make info files at 'info' time, not install-info

Thu Sep  3 16:23:00 1992  Per Bothner  ([e-mail])

	* filebuf.C:  Remove #include of <sys/file.h>.  It is not
	standard (not in Posix), and doesn't seem to be needed.

Tue Sep  1 13:10:20 1992  Per Bothner  ([e-mail])

	* filebuf.C (filebuf::sys_write):  Set error flag appropriately.
	* procbuf.C (procbuf::sys_close):  Add Posix support.
	* stdstrbufs.C: Make cerr be unbuffered.
	* iostream.h (ostream::opfx), streambuf.h (streambuf::sputc):
	Cosmetic changes; may help cfront to inline.
	* iostream.C (istream::ignore), streambuf.C (streambuf::seekmark),
	strstream.C (strstreambuf::overflow, strstreambuf::seekoff),
	parsestream.C (string_parsebuf::string_parsebuf), editbuf.C
	(edit_streambuf::seekoff), indstream.C (indirectbuf::overflow):
	Comment out default argument specifications that duplicate
	earlier definitions (to placate cfront).
	* streambuf.h, filebuf.C:  New static member filebuf::openprot
	(Non-ANSI AT&T-ism).
	* streambuf.h:  Add ios::bin enum flag, for binary I/O
	on non-Unix systems.  Unused so far.

Wed Aug 12 11:43:55 1992  Per Bothner  ([e-mail])

	* Makefile.in: 'install-info' should install iostream.info*.

Tue Aug 11 23:46:38 1992  Per Bothner  ([e-mail])

	* Makefile.in:  Bump to VERSION 0.85.

	* iostream.[hC], fstream.[hC], strstream.[hC]:  Convert to using
	multiple inheritance, with ios as a virtual base class.  I think
	this is slightly more cumbersome and inefficient, but it improves
	compatibility 	with other implementation (such as AT&T), and
	will probably be required by ANSI.  (It also allows removing some
	duplicate methods.)  Also (for compatibilty), convert operator<<
	and operator>> binary functions to unary methods.
	* stdstreams.C:  Chaneg initialization using fake_?stream
	classes to match new use of virtual base classes.
	* streambuf.h:  Make ios::~ios be virtual.

	* iostream.C (ostream::operator<<(const char* S):  Allow S
	to be NULL (in which case print "(null)").
	* igetline.C:  Set eofbit when appropriate.
	* sbufvscan .C:  Remove silly optimzation that depends on
	size_t being unsigned.
	* streambuf.h (ios::ios):  Set ios::dec initially.
	* streambuf.h, filebuf.C:  Add filebuf::setbuf(), to make sure
	that get and put areas are set up (as empty start of reserve).
	* streambuf.C (streambuf::set_column):  Don't call overflow(EOF).
	* filebuf.C (filebuf::sputn):  Fix/optimizatian for
	line-buffered files.
	* Makefile.in:  Add stdiostream.?.
	Make sure 'check' makes libio.a (since 'make all' in .. does
	not), since some tests in ./test assume libio.a.
	* iostream.texi:  Add some notes on indirectbufs and
	the new stdiobufs.
	* stdiostream.[hC]:  New files.  Defines new class stdiobuf:
	A streambuf that forwards all requests to a stdio (FILE*)
	Concept follows AT&T man pages.
	* iomanip.[hC]:  Minor improvements.

Mon Jul 27 18:24:29 1992  Per Bothner  ([e-mail])

	* dtoa.C:  Rename strtod() -> _Xstrtod(), to avoid conflicts
	with strtod() versions in shared libraries.
	* ioprivate.h: #define strtod() as _Xstrtod() (for sbufvscan.C).

Wed Jul 15 21:21:38 1992  Heinrich G. Seidl  ([e-mail])

	* iomanip.h: added parametrized manipulators.
	  iomanip.C: contains the functions, which are called by 
	  the manipulators.

Fri Jul 10 15:49:03 1992  Per Bothner  ([e-mail])

	* filebuf.C (filebuf::sys_write):  Don't use gcc-specific
	extension:  increment of a (void*) pointer.
	* igetline.C (_sb_readline):  Don't drop the last character
	of non-terminal chunks.
	* strstream.[hC]:  Remove _size, _buffer, and _frozen fields
	of a strstreambuf.  Instead, use the plethora of flags and
	fields already available in streambuf (blen(), base(), and
	_S_USER_BUF).  This makes things more consistent and simpler.
	* streambuf.h:  Add streambuf::blen() method.
	* outfloat.C (__outfloat):  Various fixes, including calculation
	of trailing_zeroes and whether to print decimal point.
	* iostream.C:  Various stylistic improvements to Mike's
	long long support:  Avoid code duplication by always using
	long long if __GNUG__ (only needed in a few places); remove
	global variable 'uppercase';  use loop to extract digits,
	rather than recursion; other optimization tweaks.

Thu Jul  2 13:59:55 1992  Mike Stump  (mrs at cygnus.com)

	* iostream.[Ch]: Implement << and >> for long long and
	unsigned long long.

Fri Jun 26 12:10:45 1992  Per Bothner  ([e-mail])

	* Makefile.in:  Increase to version 0.81.  Add a .NOEXPORT.
	* dtoa.C:  Remove some grunge.
	* iostream.h:  Add appropriate const-ness to various casts.
	* sbufvform.C, sbufvscan.C:  More const-ness fixes.
	* outfloat.C:  Different algorithm for formatting exponent.
	* parsestream.C:  Kludge to avoid warning.
	* streambuf.h:  Fix ios::operator void * to avoid
	const-ness-removing cast.
	* streambuf.C:  Kludge for Linux.

Mon Jun 22 14:45:58 1992  Per Bothner  ([e-mail])

	* sbufvform.C:  If prec is -1, use DEFPREC.

Sun Jun 21 00:33:10 1992  Per Bothner  ([e-mail])

	* streambuf.h (ios::ios):  Fix thinko.

Fri Jun 19 23:27:27 1992  Per Bothner  ([e-mail])

	* streambuf.h, iostream.[Ch]:  Remove istream/ostream/iostream
	destructors, and do the cleanup in (new) ios::~ios instead.
	Make default constructor and destructors be inline.
	* iostream.C, fstream.C:  No longer set ios::dont_close flag
	on default constructors.  In addition to being more efficient,
	this also fixes an embarassing memory leak ...
	* procbuf.C:  Remove (union wait) kludge (for NeXT).

Wed Jun 17 17:05:37 1992  Per Bothner  ([e-mail])

	* dtoa.C:  New file, derived from dtoa.h by David M. Gay
	of AT&T.  This does guaranteed accurate conversion between
	floating-pointer numbers and their string representations.
	It exports strtod() (string->double) and dtoa (double->string).
	* outfloat.C:  New file.  Exports __outfloat(), a higher-level
	interface to dtoa().
	* ioprivate.h:  Declare these new functions.
	* sbufvscan.C:  Use new strtod() to convert floats.
	* iostream.C, sbufvform.C:  Use new __outfloat function.
