The mockup example -of a "typical implementation of the sentry ctor" given in -27.6.1.1.2, p6, removed in ISO/IEC 14882:2003, doesn't show -exception handling, either. Since the ctor is not classified -as a formatted or unformatted input function, the text in -27.6.1.1, p1 through p4 does not apply. All this would seem -to suggest that the sentry ctor should not catch or in any -way handle exceptions thrown from any functions it may call. -Thus, the typical implementation of an istream extractor may -look something like [1]. +In section 24.2.6 [random.access.iterators], +Table 76 gives the return type of a[n] as convertible to T. This is +not consistent with the semantics of *(a + n) which returns T& by +Table 74. *(a + n) = t is valid while a[n] = t is invalid. </p> <p> -The problem with [1] is that while it correctly sets ios::badbit -if an exception is thrown from one of the functions called from -the sentry ctor, if the sentry ctor reaches EOF while extracting -whitespace from a stream that has eofbit or failbit set in -exceptions(), it will cause an ios::failure to be thrown, which -will in turn cause the extractor to set ios::badbit. -</p> - -<p> -The only straightforward way to prevent this behavior is to -move the definition of the sentry object in the extractor -above the try block (as suggested by the example in 22.2.8, -p9 and also indirectly supported by 27.6.1.3, p1). See [2]. -But such an implementation will allow exceptions thrown from -functions called from the ctor to freely propagate to the -caller regardless of the setting of ios::badbit in the stream -object's exceptions(). +Discussion from the Copenhagen meeting: the first part is +uncontroversial. The second part, operator[] for Random Access +Iterators, requires more thought. There are reasonable arguments on +both sides. Return by value from operator[] enables some potentially +useful iterators, e.g. a random access "iota iterator" (a.k.a +"counting iterator" or "int iterator"). There isn't any obvious way +to do this with return-by-reference, since the reference would be to a +temporary. On the other hand, <tt>reverse_iterator</tt> takes an +arbitrary Random Access Iterator as template argument, and its +operator[] returns by reference. If we decided that the return type +in Table 76 was correct, we would have to change +<tt>reverse_iterator</tt>. This change would probably affect user +code. </p> <p> -So since neither [1] nor [2] behaves as expected, the only -possible solution is to have the sentry ctor catch exceptions -thrown from called functions, set badbit, and propagate those -exceptions if badbit is also set in exceptions(). (Another -solution exists that deals with both kinds of sentries, but -the code is non-obvious and cumbersome -- see [3].) +History: the contradiction between <tt>reverse_iterator</tt> and the +Random Access Iterator requirements has been present from an early +stage. In both the STL proposal adopted by the committee +(N0527==94-0140) and the STL technical report (HPL-95-11 (R.1), by +Stepanov and Lee), the Random Access Iterator requirements say that +operator[]'s return value is "convertible to T". In N0527 +reverse_iterator's operator[] returns by value, but in HPL-95-11 +(R.1), and in the STL implementation that HP released to the public, +reverse_iterator's operator[] returns by reference. In 1995, the +standard was amended to reflect the contents of HPL-95-11 (R.1). The +original intent for operator[] is unclear. </p> <p> -Please note that, as the issue points out, current libraries -do not behave consistently, suggesting that implementors are -not quite clear on the exception handling in istream::sentry, -despite the fact that some LWG members might feel otherwise. -(As documented by the parenthetical comment here: -http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/papers/2003/n1480.html#309) +In the long term it may be desirable to add more fine-grained +iterator requirements, so that access method and traversal strategy +can be decoupled.

The two choices are equivalent except in - convoluted test cases, and many implementations already ignore the - standard and use narrow instead of widen.</p> - -<p> -First, I disagree that using narrow() instead of widen() would -necessarily have unfortunate performance implications.

In fact, the requirement in 22.4.1.1.2 -[locale.ctype.virtuals], p13 forbids narrow() to translate an alternate -digit character, wc, to an ordinary digit in the basic source -character set unless the expression -(ctype<charT>::is(ctype_base::digit, wc) == true) holds.

It involves the handling of case-insensitive matching -of character ranges such as [Z-a]. The proper behavior (according to the -ECMAScript standard) is unimplementable given the current specification -of the TR1 regex_traits<> class template. John Maddock, the author of -the TR1 regex proposal, agrees there is a problem. The full discussion -can be found at http://lists.boost.org/boost/2005/06/28850.php (first -message copied below). We don't have any recommendations as yet. -</p> -<p> --- Begin original message -- -</p> -<p> -The situation of interest is described in the ECMAScript specification -(ECMA-262), section 15.10.2.15: -</p> -<p> -"Even if the pattern ignores case, the case of the two ends of a range -is significant in determining which characters belong to the range. -Thus, for example, the pattern /[E-F]/i matches only the letters E, F, -e, and f, while the pattern /[E-f]/i matches all upper and lower-case -ASCII letters as well as the symbols [, \, ], ^, _, and `." -</p> -<p> -A more interesting case is what should happen when doing a -case-insentitive match on a range such as [Z-a]. It should match z, Z, -a, A and the symbols [, \, ], ^, _, and `. This is not what happens with -Boost.Regex (it throws an exception from the regex constructor). -</p> -<p> -The tough pill to swallow is that, given the specification in TR1, I -don't think there is any effective way to handle this situation. -According to the spec, case-insensitivity is handled with -regex_traits<>::translate_nocase(CharT) -- two characters are equivalent -if they compare equal after both are sent through the translate_nocase -function. But I don't see any way of using this translation function to -make character ranges case-insensitive. Consider the difficulty of -detecting whether "z" is in the range [Z-a]. Applying the transformation -to "z" has no effect (it is essentially std::tolower). And we're not -allowed to apply the transformation to the ends of the range, because as -ECMA-262 says, "the case of the two ends of a range is significant." -</p> -<p> -So AFAICT, TR1 regex is just broken, as is Boost.Regex. One possible fix -is to redefine translate_nocase to return a string_type containing all -the characters that should compare equal to the specified character. But -this function is hard to implement for Unicode, and it doesn't play nice -with the existing ctype facet. What a mess! -</p> -<p> --- End original message -- -</p> - -<p><i>[ -John Maddock adds: -]</i></p> - - -<p> -One small correction, I have since found that ICU's regex package does -implement this correctly, using a similar mechanism to the current -TR1.Regex. -</p> -<p> -Given an expression [c1-c2] that is compiled as case insensitive it: -</p> -<p> -Enumerates every character in the range c1 to c2 and converts it to it's -case folded equivalent. That case folded character is then used a key to a -table of equivalence classes, and each member of the class is added to the -list of possible matches supported by the character-class. This second step -isn't possible with our current traits class design, but isn't necessary if -the input text is also converted to a case-folded equivalent on the fly. -</p> -<p> -ICU applies similar brute force mechanisms to character classes such as -[[:lower:]] and [[:word:]], however these are at least cached, so the impact -is less noticeable in this case. -</p> -<p> -Quick and dirty performance comparisons show that expressions such as -"[X-\\x{fff0}]+" are indeed very slow to compile with ICU (about 200 times -slower than a "normal" expression). For an application that uses a lot of -regexes this could have a noticeable performance impact. ICU also has an -advantage in that it knows the range of valid characters codes: code points -outside that range are assumed not to require enumeration, as they can not -be part of any equivalence class. I presume that if we want the TR1.Regex -to work with arbitrarily large character sets enumeration really does become -impractical. -</p> -<p> -Finally note that Unicode has: -</p> -<p> -Three cases (upper, lower and title). -One to many, and many to one case transformations. -Character that have context sensitive case translations - for example an -uppercase sigma has two different lowercase forms - the form chosen depends -on context(is it end of a word or not), a caseless match for an upper case -sigma should match either of the lower case forms, which is why case folding -is often approximated by tolower(toupper(c)). -</p> -<p> -Probably we need some way to enumerate character equivalence classes, -including digraphs (either as a result or an input), and some way to tell -whether the next character pair is a valid digraph in the current locale. -</p> +<p><b>Rationale:</b></p> <p> -Hoping this doesn't make this even more complex that it was already, +Recommend NAD.

In the case of non-integer values of <tt>m</tt>, the -definition <tt><i>L</i><sub>n</sub><sup>(m)</sup> = (1/n!)e<sup>x</sup>x<sup>-m</sup> (d/dx)<sup>n</sup> (e<sup>-x</sup>x<sup>m+n</sup>)</tt> -must be used, which also holds for integer values of <tt>m</tt>. See -Abramowitz & Stegun, 22.11.6 for the general case, and 22.5.16-17 for -the integer case.

While the C++ 2003 standard -consistenly uses the empty exception specification, <tt>throw()</tt>, -to declare functions that are guaranteed not to throw exceptions, the -current working draft contains a number of "<i>Throws:</i> Nothing." -clause to specify essentially the same requirement. The difference -between the two approaches is that the former specifies the behavior -of programs that violate the requirement (<tt>std::unexpected()</tt> -is called) while the latter leaves the behavior undefined. - - </p> - <p> - -A survey of the working draft reveals that there are a total of 209 -occurrences of <tt>throw()</tt> in the library portion of the spec, -the majority in clause 18, a couple (literally) in 19, a handful in -20, a bunch in 22, four in 24, one in 27, and about a dozen in D.9. - - </p> - <p> - -There are also 203 occurrences of "<i>Throws:</i> Nothing." scattered -throughout the spec. - - </p> - <p> - -While sometimes there are good reasons to use the "<i>Throws:</i> -Nothing." approach rather than making use of <tt>throw()</tt>, these -reasons do not apply in most of the cases where this new clause has -been introduced and the empty exception specification would be a -better approach. - - </p> - <p> - -First, functions declared with the empty exception specification -permit compilers to generate better code for calls to such -functions.

The mockup example +of a "typical implementation of the sentry ctor" given in +27.6.1.1.2, p6, removed in ISO/IEC 14882:2003, doesn't show +exception handling, either. Since the ctor is not classified +as a formatted or unformatted input function, the text in +27.6.1.1, p1 through p4 does not apply. All this would seem +to suggest that the sentry ctor should not catch or in any +way handle exceptions thrown from any functions it may call. +Thus, the typical implementation of an istream extractor may +look something like [1]. +</p> + +<p> +The problem with [1] is that while it correctly sets ios::badbit +if an exception is thrown from one of the functions called from +the sentry ctor, if the sentry ctor reaches EOF while extracting +whitespace from a stream that has eofbit or failbit set in +exceptions(), it will cause an ios::failure to be thrown, which +will in turn cause the extractor to set ios::badbit. +</p> + +<p> +The only straightforward way to prevent this behavior is to +move the definition of the sentry object in the extractor +above the try block (as suggested by the example in 22.2.8, +p9 and also indirectly supported by 27.6.1.3, p1). See [2]. +But such an implementation will allow exceptions thrown from +functions called from the ctor to freely propagate to the +caller regardless of the setting of ios::badbit in the stream +object's exceptions(). +</p> + +<p> +So since neither [1] nor [2] behaves as expected, the only +possible solution is to have the sentry ctor catch exceptions +thrown from called functions, set badbit, and propagate those +exceptions if badbit is also set in exceptions(). (Another +solution exists that deals with both kinds of sentries, but +the code is non-obvious and cumbersome -- see [3].) +</p> + +<p> +Please note that, as the issue points out, current libraries +do not behave consistently, suggesting that implementors are +not quite clear on the exception handling in istream::sentry, +despite the fact that some LWG members might feel otherwise. +(As documented by the parenthetical comment here: +http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/papers/2003/n1480.html#309) +</p> + +<p> +Also please note that those LWG members who in Copenhagen +felt that "a sentry's constructor should not catch exceptions, +because sentries should only be used within (un)formatted input +functions and that exception handling is the responsibility of +those functions, not of the sentries," as noted here +http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/papers/2001/n1310.html#309 +would in effect be either arguing for the behavior described +in [1] or for extractors implemented along the lines of [3]. +</p> + +<p> +The original proposed resolution (Revision 25 of the issues +list) clarifies the role of the sentry ctor WRT exception +handling by making it clear that extractors (both library +or user-defined) should be implemented along the lines of +[2] (as opposed to [1]) and that no exception thrown from +the callees should propagate out of either function unless +badbit is also set in exceptions(). +</p> + + +<p>[1] Extractor that catches exceptions thrown from sentry:</p> + +<blockquote> +<pre>struct S { long i; }; + +istream& operator>> (istream &strm, S &s) +{ + ios::iostate err = ios::goodbit; + try { + const istream::sentry guard (strm, false); + if (guard) { + use_facet<num_get<char> >(strm.getloc ()) + .get (istreambuf_iterator<char>(strm), + istreambuf_iterator<char>(), + strm, err, s.i); + } + } + catch (...) { + bool rethrow; + try { + strm.setstate (ios::badbit); + rethrow = false; + } + catch (...) { + rethrow = true; + } + if (rethrow) + throw; + } + if (err) + strm.setstate (err); + return strm; +} +</pre> +</blockquote> + +<p>[2] Extractor that propagates exceptions thrown from sentry:</p> + +<blockquote> +<pre>istream& operator>> (istream &strm, S &s) +{ + istream::sentry guard (strm, false); + if (guard) { + ios::iostate err = ios::goodbit; + try { + use_facet<num_get<char> >(strm.getloc ()) + .get (istreambuf_iterator<char>(strm), + istreambuf_iterator<char>(), + strm, err, s.i); + } + catch (...) { + bool rethrow; + try { + strm.setstate (ios::badbit); + rethrow = false; + } + catch (...) { + rethrow = true; + } + if (rethrow) + throw; + } + if (err) + strm.setstate (err); + } + return strm; +} +</pre> +</blockquote> + +<p> +[3] Extractor that catches exceptions thrown from sentry +but doesn't set badbit if the exception was thrown as a +result of a call to strm.clear(). +</p> + +<blockquote> +<pre>istream& operator>> (istream &strm, S &s) +{ + const ios::iostate state = strm.rdstate (); + const ios::iostate except = strm.exceptions (); + ios::iostate err = std::ios::goodbit; + bool thrown = true; + try { + const istream::sentry guard (strm, false); + thrown = false; + if (guard) { + use_facet<num_get<char> >(strm.getloc ()) + .get (istreambuf_iterator<char>(strm), + istreambuf_iterator<char>(), + strm, err, s.i); + } + } + catch (...) { + if (thrown && state & except) + throw; + try { + strm.setstate (ios::badbit); + thrown = false; + } + catch (...) { + thrown = true; + } + if (thrown) + throw; + } + if (err) + strm.setstate (err); + + return strm; +} +</pre> +</blockquote> + +<p> +[Pre-Berlin] Reopened at the request of Paolo Carlini and Steve Clamage. +</p> + +<p> +[Pre-Portland] A relevant newsgroup post: +</p> + +<p> +The current proposed resolution of issue #309 +(http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#309) is +unacceptable.

The two choices are equivalent except in + convoluted test cases, and many implementations already ignore the + standard and use narrow instead of widen.</p> + +<p> +First, I disagree that using narrow() instead of widen() would +necessarily have unfortunate performance implications. A possible +implementation of narrow() that allows num_get to be implemented +in a much simpler and arguably comparably efficient way as calling +widen() allows, i.e. without making a virtual call to do_narrow every +time, is as follows: +</p> + +<pre> inline char ctype<wchar_t>::narrow (wchar_t wc, char dflt) const + { + const unsigned wi = unsigned (wc); + + if (wi > UCHAR_MAX) + return typeid (*this) == typeid (ctype<wchar_t>) ? + dflt : do_narrow (wc, dflt); + + if (narrow_ [wi] < 0) { + const char nc = do_narrow (wc, dflt); + if (nc == dflt) + return dflt; + narrow_ [wi] = nc; + } + + return char (narrow_ [wi]); + } +</pre> + +<p> +Second, I don't think the change proposed in the issue (i.e., to use +narrow() instead of widen() during Stage 2) would be at all +drastic. Existing implementations with the exception of libstdc++ +currently already use narrow() so the impact of the change on programs +would presumably be isolated to just a single implementation. Further, +since narrow() is not required to translate alternate wide digit +representations such as those mentioned in issue <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#303">303</a> +to +their narrow equivalents (i.e., the portable source characters '0' +through '9'), the change does not necessarily imply that these +alternate digits would be treated as ordinary digits and accepted as +part of numbers during parsing. In fact, the requirement in 22.4.1.1.2 +[locale.ctype.virtuals], p13 forbids narrow() to translate an alternate +digit character, wc, to an ordinary digit in the basic source +character set unless the expression +(ctype<charT>::is(ctype_base::digit, wc) == true) holds.

It involves the handling of case-insensitive matching +of character ranges such as [Z-a]. The proper behavior (according to the +ECMAScript standard) is unimplementable given the current specification +of the TR1 regex_traits<> class template. John Maddock, the author of +the TR1 regex proposal, agrees there is a problem. The full discussion +can be found at http://lists.boost.org/boost/2005/06/28850.php (first +message copied below). We don't have any recommendations as yet. +</p> +<p> +-- Begin original message -- +</p> +<p> +The situation of interest is described in the ECMAScript specification +(ECMA-262), section 15.10.2.15: +</p> +<p> +"Even if the pattern ignores case, the case of the two ends of a range +is significant in determining which characters belong to the range. +Thus, for example, the pattern /[E-F]/i matches only the letters E, F, +e, and f, while the pattern /[E-f]/i matches all upper and lower-case +ASCII letters as well as the symbols [, \, ], ^, _, and `." +</p> +<p> +A more interesting case is what should happen when doing a +case-insentitive match on a range such as [Z-a]. It should match z, Z, +a, A and the symbols [, \, ], ^, _, and `. This is not what happens with +Boost.Regex (it throws an exception from the regex constructor). +</p> +<p> +The tough pill to swallow is that, given the specification in TR1, I +don't think there is any effective way to handle this situation. +According to the spec, case-insensitivity is handled with +regex_traits<>::translate_nocase(CharT) -- two characters are equivalent +if they compare equal after both are sent through the translate_nocase +function. But I don't see any way of using this translation function to +make character ranges case-insensitive. Consider the difficulty of +detecting whether "z" is in the range [Z-a]. Applying the transformation +to "z" has no effect (it is essentially std::tolower). And we're not +allowed to apply the transformation to the ends of the range, because as +ECMA-262 says, "the case of the two ends of a range is significant." +</p> +<p> +So AFAICT, TR1 regex is just broken, as is Boost.Regex. One possible fix +is to redefine translate_nocase to return a string_type containing all +the characters that should compare equal to the specified character. But +this function is hard to implement for Unicode, and it doesn't play nice +with the existing ctype facet. What a mess! +</p> +<p> +-- End original message -- +</p> + +<p><i>[ +John Maddock adds: +]</i></p> + + +<p> +One small correction, I have since found that ICU's regex package does +implement this correctly, using a similar mechanism to the current +TR1.Regex. +</p> +<p> +Given an expression [c1-c2] that is compiled as case insensitive it: +</p> +<p> +Enumerates every character in the range c1 to c2 and converts it to it's +case folded equivalent. That case folded character is then used a key to a +table of equivalence classes, and each member of the class is added to the +list of possible matches supported by the character-class. This second step +isn't possible with our current traits class design, but isn't necessary if +the input text is also converted to a case-folded equivalent on the fly. +</p> +<p> +ICU applies similar brute force mechanisms to character classes such as +[[:lower:]] and [[:word:]], however these are at least cached, so the impact +is less noticeable in this case. +</p> +<p> +Quick and dirty performance comparisons show that expressions such as +"[X-\\x{fff0}]+" are indeed very slow to compile with ICU (about 200 times +slower than a "normal" expression). For an application that uses a lot of +regexes this could have a noticeable performance impact. ICU also has an +advantage in that it knows the range of valid characters codes: code points +outside that range are assumed not to require enumeration, as they can not +be part of any equivalence class. I presume that if we want the TR1.Regex +to work with arbitrarily large character sets enumeration really does become +impractical. +</p> +<p> +Finally note that Unicode has: +</p> +<p> +Three cases (upper, lower and title). +One to many, and many to one case transformations. +Character that have context sensitive case translations - for example an +uppercase sigma has two different lowercase forms - the form chosen depends +on context(is it end of a word or not), a caseless match for an upper case +sigma should match either of the lower case forms, which is why case folding +is often approximated by tolower(toupper(c)). +</p> +<p> +Probably we need some way to enumerate character equivalence classes, +including digraphs (either as a result or an input), and some way to tell +whether the next character pair is a valid digraph in the current locale. +</p> +<p> +Hoping this doesn't make this even more complex that it was already, +</p> + +<p><i>[ +Portland: Alisdair: Detect as invalid, throw an exception. +Pete: Possible general problem with case insensitive ranges. +]</i></p> + + +<p><i>[ +2009-07 Frankfurt +]</i></p> + + +<blockquote> +<p> +We agree that this is a problem, but we do not know the answer. +</p> +<p> +We are going to declare this NAD until existing practice leads us in some direction. +</p> +<p> +No objection to NAD Future. +</p> +<p> +Move to NAD Future. +</p> +</blockquote> + + + +<p><b>Proposed resolution:</b></p> + + + + + +<hr> <h3><a name="525"></a>525. type traits definitions not clear</h3> <p><b>Section:</b> 20.6.4 [meta.unary], TR1 4.5 [tr.meta.unary] <b>Status:</b> <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#NAD%20Editorial">NAD Editorial</a> <b>Submitter:</b> Robert Klarer <b>Opened:</b> 2005-07-11 <b>Last modified:</b> 2008-03-13</p> @@ -8438,7 +11071,6 @@ in the WP. <h3><a name="526"></a>526.

Instead, it appears -preferable to have the Swappable requirement defined exclusively in -terms of the existence of an appropriate swap function. +In a private email, Daveed writes: </p> +<blockquote> <p> -Section 20.1.4 [lib.swappable] of the current Working Draft (N2009) -says: +I am not familiar with the C TR, but my guess is that the +class type approach still won't match a built-in type +approach because the notion of "promotion" cannot be +emulated by user-defined types. +</p> +<p> +Here is an example: </p> -<blockquote><p> -The Swappable requirement is met by satisfying one or more of the -following conditions:</p> -<ul> -<li> -T is Swappable if T satisfies the CopyConstructible requirements -(20.1.3) and the Assignable requirements (23.1); -</li> -<li> -T is Swappable if a namespace scope function named swap exists in the -same namespace as the definition of T, such that the expression -swap(t,u) is valid and has the semantics described in Table 33. -</li> -</ul> </blockquote> -I can think of three disadvantages of this definition: -<ol> -<li> -If a client's type T satisfies the first condition (T is both -CopyConstructible and Assignable), the client cannot stop T from -satisfying the Swappable requirement without stopping T from -satisfying the first condition. -<p> -A client might want to stop T from satisfying the Swappable -requirement, because swapping by means of copy construction and -assignment might throw an exception, and she might find a throwing -swap unacceptable for her type. On the other hand, she might not feel -the need to fully implement her own swap function for this type. In -this case she would want to be able to simply prevent algorithms that -would swap objects of type T from being used, e.g., by declaring a -swap function for T, and leaving this function purposely undefined. -This would trigger a link error, if an attempt would be made to use -such an algorithm for this type. For most standard library -implementations, this practice would indeed have the effect of -stopping T from satisfying the Swappable requirement. +<pre> + struct S { + S(_Decimal32 const&); // Converting constructor + }; + void f(S); + + void f(_Decimal64); + + void g(_Decimal32 d) { + f(d); + } +</pre> + +<blockquote> +<p> +If _Decimal32 is a built-in type, the call f(d) will likely +resolve to f(_Decimal64) because that requires only a +promotion, whereas f(S) requires a user-defined conversion. </p> -</li> -<li> -A client's type T that does not satisfy the first condition can not be -made Swappable by providing a specialization of std::swap for T. <p> -While I'm aware about the fact that people have mixed feelings about -providing a specialization of std::swap, it is well-defined to do so. -It sounds rather counter-intuitive to say that T is not Swappable, if -it has a valid and semantically correct specialization of std::swap. -Also in practice, providing such a specialization will have the same -effect as satisfying the Swappable requirement. +If _Decimal32 is a class type, I think the call f(d) will be +ambiguous because both the conversion to _Decimal64 and the +conversion to S will be user-defined conversions with neither +better than the other. </p> -</li> -<li> -For a client's type T that satisfies both conditions of the Swappable -requirement, it is not specified which of the two conditions prevails. -After reading section 20.1.4 [lib.swappable], one might wonder whether -objects of T will be swapped by doing copy construction and -assignments, or by calling the swap function of T. +</blockquote> <p> -I'm aware that the intention of the Draft is to prefer calling the -swap function of T over doing copy construction and assignments.

Note +that while an optimizer may be able to tell whether a function without +an explicit exception specification can throw or not based on its +definition, it can only do so when it can see the source code of the +definition.

This is a +common situation when the called function is a C or POSIX function. + + </li> + <li> + +Alternate, proprietary mechanisms exist (such as +GCC <a href="http://gcc.gnu.org/onlinedocs/gcc-4.3.0/gcc/Function-Attributes.html#index-g_t_0040code_007bnothrow_007d-function-attribute-2160"><tt>__attribute__((nothrow))</tt></a> +or Visual +C++ <a href="http://msdn.microsoft.com/en-us/library/49147z04%28VS.80%29.aspx"><tt>__declspec(nothrow)</tt></a>) +that let implementers mark up non-throwing functions, often without +the penalty mentioned in (1) above. The C++ standard shouldn't +preclude the use of these potentially more efficient mechanisms. + + </li> + <li> + +There are functions, especially function templates, that invoke +user-defined functions that may or may not be +declared <tt>throw()</tt>. Declaring such functions with the empty +exception specification will cause compilers to generate suboptimal +code when the user-defined function isn't also declared not to throw. + + </li> + </ol> + + <p> + +The answer to point (1) above is that implementers can (and some have) +declare functions with <tt>throw()</tt> to indicate to the compiler +that calls to the function can safely be assumed not to throw in order +to allow it to generate efficient code at the call site without also +having to define the functions the same way and causing the compiler +to generate suboptimal code for the function definition. That is, the +function is declared with <tt>throw()</tt> in a header but it's +defined without it in the source file. The <tt>throw()</tt> +declaration is suppressed when compiling the definition to avoid +compiler errors. This technique, while strictly speaking no permitted +by the language, is safe and has been employed in practice. For +example, the GNU C library takes this approach. Microsoft Visual C++ +takes a similar approach by simply assuming that no function with C +language linkage can throw an exception unless it's explicitly +declared to do so using the language extension <tt>throw(...)</tt>. + + </p> + <p> + +Our answer to point (2) above is that there is no existing practice +where C++ Standard Library implementers have opted to make use of the +proprietary mechanisms to declare functions that don't throw. The +language provides a mechanism specifically designed for this +purpose. Avoiding its use in the specification itself in favor of +proprietary mechanisms defeats the purpose of the feature. In +addition, making use of the empty exception specification +inconsistently, in some areas of the standard, while conspicuously +avoiding it and making use of the "<i>Throws:</i> Nothing." form in +others is confusing to users. + + </p> + <p> + +The answer to point (3) is simply to exercise caution when declaring +functions and especially function templates with the empty exception +specification.
