abg-workers: Rework the worker queue to improve concurrent behaviour
This patch refactors the abigail::workers::queue and abigail::workers::worker implementations to avoid holding locking primitives longer than necessary. In particular, the queue_cond_mutex was held during the entiry worker runtime, effectively serializing the workers. Hence, use a mutex+cond pair for each, the input and output queue and only synchronize around the interaction with their corresponding queues. The tasks_todo_(mutex|cond) are meant to synchronize scheduling and distribution of work among workers, while tasks_done_(mutex|cond) are used for synchronizing threads when putting back the tasks to the output queue and to hold back threads waiting for the queue and workers to drain. Along that way, I did some cleanup that was now possible. - Move entire implementation of abigail::workers::task into header. - Make default_notify a static member. - Replace the multiple constructors with one with default arguments. * include/abg-workers.h (workers::task): move entire implementation to header and drop superfluous forward declaration. * src/abg-workers.cc (workers::task):: Likewise. (workers::queue::priv): Drop queue_cond_mutex, rename queue_cond to tasks_todo_cond, add task_done_cond, make default_notify static. (workers::queue::priv::priv): Add default arguments to fully qualified constructor, drop the remaining ones. (workers::queue:prive::more_tasks_to_execute): Drop method. (workers::queue:prive::schedule_task): Do not synchronize access to the queue condition variable, but only on the mutex. (do_bring_workers_down): Likewise. Also await tasks_done to be empty. (workers::queue:prive::worker::wait_to_execute_a_task): Await tasks on the tasks_todo with tasks_todo_(cond|mutex) and signal task completion to tasks_done_cond.

Add compatibility layer for C++11 mode
Introduce a compatibility layer for C++11 code by adding include/abg-cxx-compat.h. abg-cxx-compat defines a new namespace abg_compat and defines abg_compat::hash abg_compat::shared_ptr abg_compat::weak_ptr abg_compat::dynamic_pointer_cast abg_compat::static_pointer_cast abg_compat::unordered_map abg_compat::unordered_set based on definitions from std::tr1 (std=gnu++98) or std:: (std=gnu++11). I decided for introducing abg_compat:: rather than polluting abigail:: to allow an easier transition to C++11 at a later time and to not subtly break existing code. As the shared_ptr in C++11 defines shared_ptr::operator bool() explicit, some locations where a shared_ptr is assigned to boolean, needed to be adjusted to explicitly cast to bool. * include/abg-cxx-compat.h: new file introducing the abg_compat namespace to provide C++11 functionality from either std::tr1 or std:: * include/Makefile.am: Add the new abg-cxx-compat.h to source distribution. * include/abg-comparison.h: replace std::tr1 usage by abg_compat and adjust includes accordingly: likewise * include/abg-diff-utils.h: likewise * include/abg-fwd.h: likewise * include/abg-ini.h: likewise * include/abg-interned-str.h: likewise * include/abg-ir.h: likewise * include/abg-libxml-utils.h: likewise * include/abg-libzip-utils.h: likewise * include/abg-reporter.h: likewise * include/abg-sptr-utils.h: likewise * include/abg-suppression.h: likewise * include/abg-tools-utils.h: likewise * include/abg-workers.h: likewise * src/abg-comp-filter.cc: likewise * src/abg-comparison-priv.h: likewise * src/abg-corpus.cc: likewise * src/abg-dwarf-reader.cc: likewise * src/abg-hash.cc: likewise * src/abg-ir.cc: likewise * src/abg-reader.cc: likewise * src/abg-suppression.cc: likewise * src/abg-tools-utils.cc: likewise * src/abg-writer.cc: likewise * tests/test-diff-filter.cc: likewise * tests/test-diff-pkg.cc: likewise * tests/test-read-dwarf.cc: likewise * tests/test-read-write.cc: likewise * tests/test-types-stability.cc: likewise * tests/test-write-read-archive.cc: likewise * tools/abicompat.cc: likewise * tools/abidiff.cc: likewise * tools/abidw.cc: likewise * tools/abilint.cc: likewise * tools/abipkgdiff.cc: likewise Signed-off-by: Matthias Maennich <maennich@google.com> Signed-off-by: Dodji Seketeli <dodji@redhat.com> |

Several fixes and enhancements to abigail::workers
While making abipkgdiff to use the abigail::workers API to do away with using pthreads directory, it appeared that the abigail::workers API needs fixes and enhancements. Fixes ===== * Don't try to schedule a task if the pointer to the task is nil * Fix a data race when bringing workers (of a queue) down * Always try to wake up all waiting threads when bringing down queue workers. * Fix a data race when accessing the queue condition variable * Fix a data race when notifying listeners about the end of the job performed by the task. Enhancements ============ * Pass the "task done" notifier by reference, to the worker queue. Without this, the worker queue needs to copy the "task done" notifier by value. This implies that user code needs to provide task done notifier instances that come with potentially complicated copy constructors. By passing it by reference and by just re-using the notifier from the user code, we do away with the need for copying altogether. This also fixes some latent copying bugs. * Add a workers::queue::schedule_tasks() method This allows user code to schedule a vector of tasks at once. * make workers::queue::get_completed_tasks() return a non-const vector This enables user code to sort the completed tasks as they wish. * include/abg-workers.h (queue::tasks_type): New typedef. (queue::queue): Pass task_done_notify by reference. (queue::schedule_tasks): Declare new member function. (queue::get_completed_tasks): Return non-const vector. * src/abg-workers.cc (queue::priv::default_notify): New data member. (queue::priv::notify): Make this data member be a reference. (queue::priv::priv): Initialize the notify data member to either the new default_notify (if no notifier is provided by the constructor) or to the notifier provided by the constructor. (queue::priv::schedule_task): Do not schedule a nil task. Update comment. (queue::priv::schedule_tasks): Add a new member function. (queue::priv::do_bring_workers_down): Update comment. Protect access to "bring_workers_down" with tasks_todo_mutex to prevent a data race. Call pthread_cond_broadcast on the queue_cond unconditionaly to prevent some worker threads to keep waiting for ever. Also, protect the access to the queue_cond by the queue_cond_mutex to precent a data race. (queue::queue): Pass the notifier by reference. Update comment. (queue::schedule_task): Update comment. (queue::schedule_tasks): Define new member function. (queue::wait_for_workers_to_complete): Update comment. (queue::get_completed_tasks): Return a non-const vector. Update comment. (worker::wait_to_execute_a_task): Update several comments. Make the execution of the notification code to be synchronized (on the tasks_done_mutex). Signed-off-by: Dodji Seketeli <dodji@redhat.com> |

Use worker threads pattern to speed up some tests
We are going to need to speed up more and more tests, and coding directly with libpthread for that can be tedious and bug-prone. So I devised an implementation for the worker threads design pattern instead, and used it to speed up some tests. * include/Makefile.am: Add the new abg-workers.h to source distribution. * include/abg-workers.h: New file. * src/Makefile.am: Add the new abg-worker.cc to source distribution. * src/abg-workers.cc: New file. * tests/test-utils.cc: Update copyright. Make get_src_dir() and get_build_dir() return a const char*, as opposed to returning a string. Make that const char reside in thread local storage, so that two concurrent threads can safely call these functions in parallel, without any race. * tests/test-utils.h: Make get_src_dir() and get_build_dir() return a const char*, as opposed to returning a string. * tests/test-abicompat.cc: Update copyright. Adjust for get_src_dir() and get_build_dir() change. * tests/test-abidiff.cc: Likewise. * tests/test-alt-dwarf-file.cc: Likewise. * tests/test-core-diff.cc: Likewise. * tests/test-diff-dwarf-abixml.cc: Likewise. * tests/test-diff-dwarf.cc: Likewise. * tests/test-diff-pkg.cc: Likewise. * tests/test-diff-suppr.cc: Likewise. * tests/test-lookup-syms.cc: Likewise. * tests/test-read-dwarf.cc: Likewise. * tests/test-read-write.cc: Likewise. * tests/test-types-stability.cc: Likewise.
