If don’t, garbage characters can be inserted to the front of external buffer in underflow(). Because underflow() copies remaining characters in external buffer to it’s front. This results wrong characters insertion when seekpos() or seekoff() is called.

e103a3d69bAndrew Morrow: The current CMake setup for libc++ incorrectly uses the variable LLVM_ENABLE_ASSERTIONS instead of LIBCXX_ENABLE_ASSERTIONS when figuring out what _DEBUG/NDEBUG defines to set. It also tries to test the non-existent variable 'uppercase_CMAKE_BUILD_TYPE', which the top level LLVM CMakeLists.txt sets up, but which the top level libc++ CMakeLists.txt currently does not. Changing the variable name tested and creating the uppercase release name variable allows libc++ to honor the LIBCXX_ENABLE_ASSERTIONS option correctly.

ef793f2513Andrew Morrow: Among the various libc++ tests that currently don't pass on Linux are localization/locale.categories/category.collate/category.ctype/locale.ctype.byname/is_1.pass.cpp and scan_is.pass.cpp. The tests fail when the character class being tested is compound, like ctype_base::alnum or ctype_base::graph, because the existing series of conditionals in do_is an do_scan_is will abort too early. For instance, if the character class being tested is alnum, and the character is numeric, do_is will return false because iswalpha_l will return false, 'result' becomes false, and the 'true' result from the later call to iswdigit_l ends up being ignored . A similar problem exists in do_scan_is.

In my experience, putting in a yield for every failed iteration is also a major performance booster. This change makes one of the performance tests I was using (a highly contended one) run about 20 times faster.

In general it has not been decided exactly how libc++ will track changes made to C++11. New features and design changes will probably be #ifdef'd, especially if they are not backwards compatible. Defects and 'dumb mistakes' are more likely to just be put in. Decisions on telling one from the other will be made on a case by case basis.

7a44515588This commit establishes a new bucket_count policy in the unordered containers: The policy now allows a power-of-2 number of buckets to be requested (and that request honored) by the client. And if the number of buckets is set to a power of 2, then the constraint of the hash to the number of buckets uses & instead of %. If the client does not specify a number of buckets, then the policy remains unchanged: a prime number of buckets is selected. The growth policy is that the number of buckets is roughly doubled when needed. While growing, either the prime, or the power-of-2 strategy will be preserved. There is a small run time cost for putting in this switch. For very cheap hash functions, e.g. identity for int, the cost can be as high as 18%. However with more typical use cases, e.g. strings, the cost is in the noise level. I've measured cases with very cheap hash functions (int) that using a power-of-2 number of buckets can make look up about twice as fast. However I've also noted that a power-of-2 number of buckets is more susceptible to accidental catastrophic collisions. Though I've also noted that accidental catastrophic collisions are also possible when using a prime number of buckets (but seems far less likely). In short, this patch adds an extra tuning knob for those clients trying to get the last bit of performance squeezed out of their hash containers. Casual users of the hash containers will not notice the introduction of this tuning knob. Those clients who swear by power-of-2 hash containers can now opt-in to that strategy. Clients who prefer a prime number of buckets can continue as they have.

635ce1d127The rules for emplace in map, multimap, unordered_map and unordered_multimap changed a while back and I'm just now updating to these new rules. In a nutshell, you've got to know you're emplacing to a pair and use one of pair's constructors. I made one extension: If you want to emplace the key and default construct the mapped_type, you can just emplace(key), as opposed to emplace(piecewise_construct, forward_as_tuple(key), forward_as_tuple()).
