Take maintainership Update to v1.10 == 21 January 2011 == I've just released sparsehash 1.10. This fixes a performance regression in sparsehash 1.8, where sparse_hash_map would copy hashtable keys by value even when the key was explicitly a reference. It also fixes compiler warnings from MSVC 10, which uses some c++0x features that did not interact well with sparsehash. There is no reason to upgrade unless you use references for your hashtable keys, or compile with MSVC 10. A full list of changes is described in [http://google-sparsehash.googlecode.com/svn/tags/sparsehash-1.10/ChangeLog ChangeLog]. === 24 September 2010 === I've just released sparsehash 1.9. This fixes a size regression in sparsehash 1.8, where the new allocator would take up space in `sparse_hash_map`, doubling the sparse_hash_map overhead (from 1-2 bits per bucket to 3 or so). All users are encouraged to upgrade. This change also marks enums as being Plain Old Data, which can speed up hashtables with enum keys and/or values. A full list of changes is described in [http://google-sparsehash.googlecode.com/svn/tags/sparsehash-1.9/ChangeLog ChangeLog]. === 29 July 2010 === I've just released sparsehash 1.8. This includes improved support for `Allocator`, including supporting the allocator constructor arg and `get_allocator()` access method. To work around a bug in gcc 4.0.x, I've renamed the static variables `HT_OCCUPANCY_FLT` and `HT_SHRINK_FLT` to `HT_OCCUPANCY_PCT` and `HT_SHRINK_PCT`, and changed their type from float to int. This should not be a user-visible change, since these variables are only used in the internal hashtable classes (sparsehash clients should use `max_load_factor()` and `min_load_factor()` instead of modifying these static variables), but if you do access these constants, you will need to change your code. Internally, the biggest change is a revamp of the test suite. It now has more complete coverage, and a more capable timing tester. There are other, more minor changes as well. A full list of changes is described in the [http://google-sparsehash.googlecode.com/svn/tags/sparsehash-1.8/ChangeLog ChangeLog]. === 31 March 2010 === I've just released sparsehash 1.7. The major news here is the addition of `Allocator` support. Previously, these hashtable classes would just ignore the `Allocator` template parameter. They now respect it, and even inherit `size_type`, `pointer`, etc. from the allocator class. By default, they use a special allocator we provide that uses libc `malloc` and `free` to allocate. The hash classes notice when this special allocator is being used, and use `realloc` when it can. This means that the default allocator is significantly faster than custom allocators are likely to be (since realloc-like functionality is not supported by STL allocators). There are a few more minor changes as well. A full list of changes is described in the [http://google-sparsehash.googlecode.com/svn/tags/sparsehash-1.7/ChangeLog ChangeLog]. === 11 January 2010 === I've just released sparsehash 1.6. The API has widened a bit with the addition of `deleted_key()` and `empty_key()`, which let you query what values these keys have. A few rather obscure bugs have been fixed (such as an error when copying one hashtable into another when the empty_keys differ). A full list of changes is described in the [http://google-sparsehash.googlecode.com/svn/tags/sparsehash-1.6/ChangeLog ChangeLog]. === 9 May 2009 === I've just released sparsehash 1.5.1. Hot on the heels of sparsehash 1.5, this release fixes a longstanding bug in the sparsehash code, where `equal_range` would always return an empty range. It now works as documented. All sparsehash users are encouraged to upgrade. === 7 May 2009 === I've just released sparsehash 1.5. This release introduces tr1 compatibility: I've added `rehash`, `begin(i)`, and other methods that are expected to be part of the `unordered_map` API once `tr1` in introduced. This allows `sparse_hash_map`, `dense_hash_map`, `sparse_hash_set`, and `dense_hash_set` to be (almost) drop-in replacements for `unordered_map` and `unordered_set`. There is no need to upgrade unless you need this functionality, or need one of the other, more minor, changes described in the [http://google-sparsehash.googlecode.com/svn/tags/sparsehash-1.5/ChangeLog ChangeLog].

Give up maintainership, as I have not so much as looked at pkgsrc in

well over a year now. Sorry. :-(

Add DESTDIR support.

Mon May 2 07:04:46 2005 Google Inc. * sparsehash: version 0.2 release * Preliminary support for msvc++ compilation. (csilvers) * Documentation fixes -- some example code was incomplete! (csilvers) * Minimize size of config.h to avoid other-package conflicts (csilvers) * Contribute a C-based version of sparsehash that served as the inspiration for this code. One day, I hope to clean it up and support it, but for now it's just in experimental/, for playing around with. (csilvers) * Change default namespace from std to google. (csilvers) Thu Nov 3 20:12:31 2005 Google Inc. * sparsehash: version 0.3 release * Quiet compiler warnings on some compilers. (csilvers) * Some documentation fixes: example code for dense_hash_map. (csilvers) * Fix a bug where swap() wasn't swapping delete_key(). (csilvers) * set_deleted_key() and set_empty_key() now take a key only, allowing hash-map values to be forward-declared. (csilvers) * support for std::insert_iterator (and std::inserter). (csilvers) Sun Apr 23 22:42:35 2006 Google Inc. * sparsehash: version 0.4 release * Remove POD requirement for keys and values!
