5: + code until an issue has reached DR status. +

5: string::compare specification questionable

This should be two overloaded functions rather than a single function. -

17: +

17: Bad bool parsing

Apparently extracting Boolean values was messed up... -

19: +

19: "Noconv" definition too vague

If codecvt::do_in returns noconv there are no changes to the values in [to, to_limit). -

22: +

22: Member open vs flags

Re-opening a file stream does not clear the state flags. -

23: +

23: Num_get overflow result

Implement the proposed resolution. -

25: +

25: String operator<< uses width() value wrong

Padding issues. -

48: +

48: Use of non-existent exception constructor

An instance of ios_base::failure is constructed instead. -

49: +

49: Underspecification of ios_base::sync_with_stdio

The return type is the previous state of synchronization. -

50: +

50: Copy constructor and assignment operator of ios_base

These members functions are declared private and are thus inaccessible. Specifying the correct semantics of "copying stream state" was deemed too complicated. -

60: +

60: What is a formatted input function?

This DR made many widespread changes to basic_istream and basic_ostream all of which have been implemented. -

63: +

63: Exception-handling policy for unformatted output

Make the policy consistent with that of formatted input, unformatted input, and formatted output. -

68: +

68: Extractors for char* should store null at end

And they do now. An editing glitch in the last item in the list of [27.6.1.2.3]/7. -

74: +

74: Garbled text for codecvt::do_max_length

The text of the standard was gibberish. Typos gone rampant. -

75: +

75: Contradiction in codecvt::length's argument types

Change the first parameter to stateT& and implement the new effects paragraph. -

83: +

83: string::npos vs. string::max_size()

Safety checks on the size of the string should test against max_size() rather than npos. -

90: +

90: Incorrect description of operator>> for strings

The effect contain isspace(c,getloc()) which must be replaced by isspace(c,is.getloc()). -

91: +

91: Description of operator>> and getline() for string<> might cause endless loop

They behave as a formatted input function and as an unformatted input function, respectively (except that getline is not required to set gcount). -

103: +

103: set::iterator is required to be modifiable, but this allows modification of keys.

For associative containers where the value type is the same as the key type, both iterator and const_iterator are constant iterators. -

109: +

109: Missing binders for non-const sequence elements

The binder1st and binder2nd didn't have an operator() taking a non-const parameter. -

110: +

110: istreambuf_iterator::equal not const

This was not a const member function. Note that the DR says to replace the function with a const one; we have instead provided an overloaded version with identical contents. -

117: +

117: basic_ostream uses nonexistent num_put member functions

num_put::put() was overloaded on the wrong types. -

118: +

118: basic_istream uses nonexistent num_get member functions

Same as 117, but for num_get::get(). -

129: +

129: Need error indication from seekp() and seekg()

These functions set failbit on error now. -

130: +

130: Return type of container::erase(iterator) differs for associative containers

Make member erase return iterator for set, multiset, map, multimap. -

136: +

136: seekp, seekg setting wrong streams?

seekp should only set the output stream, and seekg should only set the input stream. -

167: +

167: Improper use of traits_type::length()

op<< with a const char* was calculating an incorrect number of characters to write. -

169: +

169: Bad efficiency of overflow() mandated

Grow efficiently the internal array object. -

171: +

171: Strange seekpos() semantics due to joint position

Quite complex to summarize... -

181: +

181: make_pair() unintended behavior

This function used to take its arguments as reference-to-const, now it copies them (pass by value). -

195: +

195: Should basic_istream::sentry's constructor ever set eofbit?

Yes, it can, specifically if EOF is reached while skipping whitespace. -

206: +

206: operator new(size_t, nothrow) may become unlinked to ordinary operator new if ordinary version replaced @@ -144,97 +144,97 @@

The nothrow forms of new and delete were changed to call the throwing forms, handling any exception by catching it and returning a null pointer. -

211: +

211: operator>>(istream&, string&) doesn't set failbit

If nothing is extracted into the string, op>> now sets failbit (which can cause an exception, etc., etc.). -

214: +

214: set::find() missing const overload

Both set and multiset were missing overloaded find, lower_bound, upper_bound, and equal_range functions for const instances. -

231: +

231: Precision in iostream?

For conversion from a floating-point type, str.precision() is specified in the conversion specification. -

233: +

233: Insertion hints in associative containers

Implement N1780, first check before then check after, insert as close to hint as possible. -

235: +

235: No specification of default ctor for reverse_iterator

The declaration of reverse_iterator lists a default constructor. However, no specification is given what this constructor should do. -

241: +

241: Does unique_copy() require CopyConstructible and Assignable?

Add a helper for forward_iterator/output_iterator, fix the existing one for input_iterator/output_iterator to not rely on Assignability. -

243: +

243: get and getline when sentry reports failure

Store a null character only if the character array has a non-zero size. -

251: +

251: basic_stringbuf missing allocator_type

This nested typedef was originally not specified. -

253: +

253: valarray helper functions are almost entirely useless

Make the copy constructor and copy-assignment operator declarations public in gslice_array, indirect_array, mask_array, slice_array; provide definitions. -

265: +

265: std::pair::pair() effects overly restrictive

The default ctor would build its members from copies of temporaries; now it simply uses their respective default ctors. -

266: +

266: bad_exception::~bad_exception() missing Effects clause

The bad_* classes no longer have destructors (they are trivial), since no description of them was ever given. -

271: +

271: basic_iostream missing typedefs

The typedefs it inherits from its base classes can't be used, since (for example) basic_iostream<T>::traits_type is ambiguous. -

275: +

275: Wrong type in num_get::get() overloads

Similar to 118. -

280: +

280: Comparison of reverse_iterator to const reverse_iterator

Do not specify what codecvt<wchar_t, char, mbstate_t>::do_length must return. -
