* include/std/std_sstream.h (_M_sync): When the caller is
setbuf, don't trust _M_string.capacity() to be the size of
the buffer area, use _M_string.size() in this case.
* testsuite/27_io/basic_stringbuf/setbuf/char/4.cc: New.
* testsuite/27_io/basic_stringbuf/setbuf/wchar_t/4.cc: Likewise.
* include/bits/sstream.tcc (overflow): Avoid calling string::assign
unnecessarily when the current _M_string is empty.
2004-10-06 Paolo Carlini <pcarlini@suse.de>
* include/bits/stl_algo.h (__reverse(bidirectional_iterator_tag)):
Avoid iterator postincrement.
(__rotate): Likewise.
* include/bits/stl_algo.h: Minor formatting tweaks.

* include/bits/stl_algo.h (__reverse(random_access_iterator_tag)):
Avoid iterator postincrement; fix swapping middle element with
itself on odd-length inputs.

2004-10-05 Christopher Jefferson <caj@cs.york.ac.uk>
* include/bits/stl_algobase.h (iter_swap): delegate to swap via
__iter_swap when iterator's value_types are equal.
(struct __iter_swap): New.

* include/bits/sstream.tcc (seekpos): Minor rearrangement of two
conditionals consistently with seekoff.
* include/std/std_sstream.h (setbuf): Avoid a string temporary.
(_M_sync): Simplify a bit, clean-up comment.

2004-09-29 Paolo Carlini <pcarlini@suse.de>
* include/std/std_sstream.h (basic_stringbuf(ios_base::openmode)):
Don't use _M_stringbuf_init, keep the pointers null, per 27.7.1.1.
(str()): Slightly tweak, protect from pptr() == 0.
(_M_update_egptr()): Likewise.
* include/bits/sstream.tcc (ssekoff, seekpos): In order to check
for an empty buffer use __beg instead of _M_string.capacity().
* testsuite/27_io/basic_stringbuf/cons/char/1.cc: New.
* testsuite/27_io/basic_stringbuf/cons/wchar_t/1.cc: Likewise.
* testsuite/27_io/basic_filebuf/cons/char/1.cc: New.
* testsuite/27_io/basic_filebuf/cons/wchar_t/1.cc: Likewise.
* testsuite/27_io/basic_streambuf/cons/char/1.cc: Update.
* testsuite/27_io/basic_streambuf/cons/wchar_t/1.cc: Likewise.

Benjamin Kosnik <bkoz@redhat.com>
* testsuite/testsuite_io.h (class constraint_buf): New, extended
and templatized version of constraint_filebuf; add typedefs for
streambuf/stringbuf/filebuf and wchar_t counterparts.

* include/bits/fstream.tcc (xsgetn): Slightly tweak conditional,
as per Nathan's original suggestion.

Andrea Arcangeli <andrea@suse.de>
* config/io/basic_file_stdio.cc (__basic_file<>::close)): Don't
call unnecessarily sync, that is fflush: the library, since 3.4.0
does not use buffered fread/fwrite.
* include/bits/fstream.tcc (basic_filebuf<>::overflow): Likewise.

2004-09-14 Nathan Myers <ncm@cantrip.org>
* include/bits/fstream.tcc (xsgetn): Slightly tweak the recent fix
for 11722: copy can replace move; the common case is __avail == 0.
From-SVN: r87501
2004-09-14 Paolo Carlini <pcarlini@suse.de>
* include/bits/cpp_type_traits.h: Rename __is_trivially_copyable
to __is_scalar, more clear and consistent with "tr1" naming.
* include/bits/stl_algobase.h: Update consistently throughout.

* include/std/std_fstream.h (xsgetn): Declare only.
* include/bits/fstream.tcc (xsgetn): Define, optimize for the
always_noconv() case: when __n > __buflen, copy the available
buffer and issue a direct read.
* testsuite/performance/27_io/filebuf_sgetn_unbuf.cc: New.
* include/bits/fstream.tcc (xsputn): Minor tweak, reorder a
