2024-07-24libstdc++: Add file-io-diff to replace @diff@ markup in I/O testsJonathan Wakely12-37/+73
This adds a new dg-final action to compare two files after a test has run, so that we can verify that fstream operations produce the expected results. With this change, all uses of @diff@ that seem potentially useful have been converted to actually compare the files and FAIL if they differ. The file-io-diff action can take two arguments naming the files to be compared, or for convenience it can take a single string and will compare STR.tst and STR.txt, as that's how it's commonly used. Additionally, all remaining uses of @require@ are converted to dg-additional-files directives, so that the TODO in libstdc++.exp can be resolved. libstdc++-v3/ChangeLog: * testsuite/27_io/basic_filebuf/close/char/1.cc: Remove @require@ and @diff@.

2024-07-24libstdc++: Replace @require@ markup in some I/O testsJonathan Wakely8-24/+16
We can replace the @require@ markup with { dg-additional-files ... } directives, so that the required files are explicitly named and are explicitly copied into place for tests that require it. This will allow a later change to remove the "Copy all required data files" step in the proc libstdc++_init in testsuite/lib/libstdc++.exp that is marked TODO. This commit uses dg-additional-files for a subset of the files that contain @require@. Also remove the @diff@ markup where appears to be copy & pasted from other test files, and so serves no purpose. For example, there is no output file created by 27_io/basic_ifstream/cons/char/1.cc so there is nothing for @diff@ to compare. Maybe the purpose was to check that reading the .tst file with an ifstream doesn't change it, but we've survived without doing those comparisons for many years so I think we can remove those cases of @diff@ markup. libstdc++-v3/ChangeLog: * testsuite/27_io/basic_filebuf/close/char/2.cc: Remove @require@ and @diff@ markup.

2024-04-15libstdc++: Fix infinite loop in std::istream::ignore(n, delim) [PR93672]Jonathan Wakely2-0/+135
A negative delim value passed to std::istream::ignore can never match any character in the stream, because the comparison is done using traits_type::eq_int_type(sb->sgetc(), delim) and sgetc() never returns negative values (except at EOF). The optimized version of ignore for the std::istream specialization uses traits_type::find to locate the delim character in the streambuf, which _can_ match a negative delim on platforms where char is signed, but then we do another comparison using eq_int_type which fails. The code then keeps looping forever, with traits_type::find locating the character and traits_type::eq_int_type saying it's not a match, so traits_type::find is used again and finds the same character again. A possible fix would be to check with eq_int_type after a successful find, to see whether we really have a match. However, that would be suboptimal since we know that a negative delimiter will never match using eq_int_type. So a better fix is to adjust the check at the top of the function that handles delim==eof(), so that we treat all negative delim values as equivalent to EOF. That way we don't bother using find to search for something that will never match with eq_int_type. The version of ignore in the primary template doesn't need a change, because it doesn't use traits_type::find, instead characters are extracted one-by-one and always matched using eq_int_type. That avoids the inconsistency between find and eq_int_type. The specialization for std::wistream does use traits_type::find, but traits_type::to_int_type is equivalent to an implicit conversion from wchar_t to wint_t, so passing a wchar_t directly to ignore without using to_int_type works. libstdc++-v3/ChangeLog: PR libstdc++/93672 * src/c++98/istream.cc (istream::ignore(streamsize, int_type)): Treat all negative delimiter values as eof(). * testsuite/27_io/basic_istream/ignore/char/93672.cc: New test. * testsuite/27_io/basic_istream/ignore/wchar_t/93672.cc: New test.

2022-07-12libstdc++: Check for EOF if extraction avoids buffer overflow [PR106248]Jonathan Wakely2-0/+80
In r11-2581-g17abcc77341584 (for LWG 2499) I added overflow checks to the pre-C++20 operator>>(istream&, char*) overload. Those checks can cause extraction to stop after filling the buffer, where previously it would have tried to extract another character and stopped at EOF. When that happens we no longer set eofbit in the stream state, which is consistent with the behaviour of the new C++20 overload, but is an observable and unexpected change in the C++17 behaviour. What makes it worse is that the behaviour change is dependent on optimization, because __builtin_object_size is used to detect the buffer size and that only works when optimizing. To avoid the unexpected and optimization-dependent change in behaviour, set eofbit manually if we stopped extracting because of the buffer size check, but had reached EOF anyway. If the stream's rdstate() != goodbit or width() is non-zero and smaller than the buffer, there's nothing to do. Otherwise, we filled the buffer and need to check for EOF, and maybe set eofbit. The new check is guarded by #ifdef __OPTIMIZE__ because otherwise __builtin_object_size is useless. There's no point compiling and emitting dead code that can't be eliminated because we're not optimizing. We could add extra checks that the next character in the buffer is not whitespace, to detect the case where we stopped early and prevented a buffer overflow that would have happened otherwise. That would allow us to assert or set badbit in the stream state when undefined behaviour was prevented. However, those extra checks would increase the size of the function, potentially reducing the likelihood of it being inlined, and so making the buffer size detection less reliable. It seems preferable to prevent UB and silently truncate, rather than miss the UB and allow the overflow to happen. libstdc++-v3/ChangeLog: PR libstdc++/106248 * include/std/istream [C++17] (operator>>(istream&, char*)): Set eofbit if we stopped extracting at EOF. * testsuite/27_io/basic_istream/extractors_character/char/pr106248.cc: New test. * testsuite/27_io/basic_istream/extractors_character/wchar_t/pr106248.cc: New test.

P0487R1 resolved LWG 2499 for C++20 by removing the operator>> overloads that have high risk of buffer overflows. They were replaced by equivalents that only accept a reference to an array, and so can guarantee not to write past the end of the array. In order to support both the old and new functionality, this patch introduces a new overloaded __istream_extract function which takes a maximum length. The new operator>> overloads use the array size as the maximum length. The old overloads now use __builtin_object_size to determine the available buffer size if available (which requires -O2) or use numeric_limits<streamsize>::max()/sizeof(char_type) otherwise. This is a change in behaviour, as the old overloads previously always used numeric_limits<streamsize>::max(), without considering sizeof(char_type) and without attempting to prevent overflows. Because they now do little more than call __istream_extract, the old operator>> overloads are very small inline functions. This means there is no advantage to explicitly instantiating them in the library (in fact that would prevent the __builtin_object_size checks from ever working). As a result, the explicit instantiation declarations can be removed from the header. The explicit instantiation definitions are still needed, for backwards compatibility with existing code that expects to link to the definitions in the library. While working on this change I noticed that src/c++11/istream-inst.cc has the following explicit instantiation definition: template istream& operator>>(istream&, char*); This had no effect (and so should not have been present in that file), because there was an explicit specialization declared in <istream> and defined in src/++98/istream.cc. However, this change removes the explicit specialization, and now the explicit instantiation definition is necessary to ensure the symbol gets defined in the library. libstdc++-v3/ChangeLog: * config/abi/pre/gnu.ver (GLIBCXX_3.4.29): Export new symbols. * include/bits/istream.tcc (__istream_extract): New function template implementing both of operator>>(istream&, char*) and operator>>(istream&, char(&)[N]).

2020-07-20libstdc++: Avoid overflow in istream::get(streambuf&) [LWG 3464]Jonathan Wakely2-0/+182
Similar to the recent changes to basic_istream::ignore, this change ensures that _M_gcount doesn't overflow when extracting characters and inserting them into another streambuf. The solution used here is to use unsigned long long for the count. We assume that the number of characters extracted won't exceed the maximum value for that type, but even if it does we avoid any undefined behaviour. libstdc++-v3/ChangeLog: * include/bits/istream.tcc (basic_istream::get(__streambuf_type&, char_type): Use unsigned long long for counter and check if it would overflow _M_gcount. * testsuite/27_io/basic_istream/get/char/lwg3464.cc: New test. * testsuite/27_io/basic_istream/get/wchar_t/lwg3464.cc: New test.
2020-07-13libstdc++: Fix istream::ignore exit conditions (PR 94749, PR 96161)Jonathan Wakely4-2/+462
My previous fix for PR 94749 did fix the reported case, so that the next character is not discarded if it happens to equal the delimiter when __n characters have already been read. But it introduced a new bug, which is that the delimiter character would *not* be discarded if the number of characters discarded is numeric_limits<streamsize>::max() or more before reaching the delimiter. The new bug happens because I changed the code to check _M_gcount < __n. But when __n == numeric_limits<streamsize>::max() that is false, and so we don't discard the delimiter. It's not sufficient to check for the delimiter when the __large_ignore condition is true, because there's an edge case where the delimiter is reached when _M_gcount == __n and so we break out of the loop without setting __large_ignore. PR 96161 is a similar bug to the original PR 94749 report, where eofbit is set after discarding __n characters if there happen to be no more characters in the stream. This patch fixes both cases (and the regression) by checking different conditions for the __n == max case and the __n < max case. For the former case, we know that we must have either reached the delimiter or EOF, and the value of _M_gcount doesn't matter (except to avoid integer overflow). For the latter case we need to check _M_gcount first and only set eofbit or discard the delimiter if it didn't reach __n. For the latter case overflow can't happen because _M_gcount <= __n < max. libstdc++-v3/ChangeLog: PR libstdc++/94749 PR libstdc++/96161 * include/bits/istream.tcc (basic_istream::ignore(streamsize)) [n == max]: Check overflow conditions on _M_gcount.

2020-06-11libstdc++: Fix istream::ignore discarding too many chars (PR 94749)Jonathan Wakely2-0/+152
The current code assumes that if the next character in the stream is equal to the delimiter then we stopped because we saw that delimiter, and so discards it. But in the testcase for the PR we stop because we reached the maximum number of characters, and it's coincidence that the next character equals the delimiter. We should not discard the next character in that case. The fix is to check that we haven't discarded __n characters already, instead of checking whether the next character equals __delim. Because we've already checked for EOF, if we haven't discarded __n yet then we know we stopped because we saw the delimiter. On the other hand, if the next character is the delimiter we don't know if that's why we stopped.
