This is the last patch release for libpmemobj-cpp 1.10 version. Maintenance of this version is no longer supported. It contains all bugfixes and updates from previous patch releases (1.9.1, 1.8.2, 1.7.1, 1.6.1, 1.5.2).

This release fixes minor bugs.

Notable changes:

• concurrent_hash_map: fix free_data()
• concurrent_hash_map: make double to size_t cast explicit in defragment()
• peristent_ptr: add missing offset calculation

This release fixes minor bugs.

This is the last patch release for libpmemobj-cpp 1.8 version. Maintenance of this version is no longer supported.

Notable changes:

• vector: fix referencing empty array
• vector: Fix undefined behaviour on realloc

This release fixes minor bugs.

This is the last patch release for libpmemobj-cpp 1.7 version. Maintenance of this version is no longer supported.

Notable changes:

• Properly install pkg-config file for all configurations
• Fix void_t declaration and API usage for concurrent hashmap test

This release introduces new concurrent data structure - MPSC queue and implements limited concurrency support for radix tree.

New features:

• Introduce experimental MPSC queue (pmem::obj::experimental::mpsc_queue)
• Implement support for multi-reader single-writer concurrency in pmem::obj::experimental::radix_tree
• Introduce basic_dram_inline_string which can be kept both on pmem and dram

Bug fixes:

• Fix radix_tree leaf layout to ensure proper key/value alignment

Other changes:

• Switch default CMake's build type from "Debug" to "RelWithDebInfo" it's relevant for a GitHub users (who may e.g. run some benchmarks)
• Add std::initializer_list constructor to pmem::obj::array to mimic aggregate initialization post C++20

This release fixes minor bugs.

This is the last patch release for libpmemobj-cpp 1.6 version. Maintenance of this version is no longer supported.

Notable changes:

• string: fix max_size() return value
• allocation_flag: mark constructor as explicit
• peristent_ptr: change ptr_offset_magic to be properly aligned
• fix few headers' includes

This release fixes minor bugs.

This is the last patch release for libpmemobj-cpp 1.5 version. Maintenance of this version is no longer supported.

Notable changes:

• operator[] for contiguous_iterator takes signed integral instead of unsigned
• throw an exception when pmemobj_mutex_unlock fail
• fix crash when a previous transaction failed to start because of already taken lock.

This release introduces new transaction handler type (flat_transaction) which solves https://github.com/pmem/libpmemobj-cpp/issues/516 (more information can be found in README).

It also introduces several improvements and bugfixes for radix_tree as well as additional methods for pmem::obj::string_view.

New features:

• pmem::obj::flat_transaction
• extend API for pmem::obj::string_view (relational operators, find, substr, copy, compare)

Bug fixes:

• make default bytes_view implementation in radix_tree work for wide characters
• fix assign_val function in radix tree which incorrectly handled inline_string<CharT> for CharT != char
• fix use after free in radix_tree::erase method

Other changes:

• allow using any iterator which supports operator[], operator-() and operator--() in pmem::obj::slice

This release introduces a new experimental container - persistent radix_tree along with inline_string and string_view classes.

It also introduces a new pointer type: self_relative_ptr with std::atomic specialization.

New features:

• experimental radix_tree container (single-threaded sorted map)
• experimental inline_string class (class serves similar purpose to pmem::obj::string, but keeps the data within the same allocation as inline_string itself)
• string_view class (support for compilers older than C++17)
• experimental self_relative_ptr and std::atomic<self_relative_ptr> specialization (persistent smart ptr which encapsulates the self offseted pointer and provides member access, dereference and array access operators - for some workloads it could be faster alternative for persistent_ptr)

Optimizations:

• optimizations for concurrent_map with self_relative_ptr

Other changes:

• missing constructors for basic_string class
• conversion operator for basic_string class
• ported libcxx's sorted map tests
• lower and lower_eq methods for concurrent_map
• missing constructor for concurrent_map (comparator as an argument)
