With this patch, the code of abipkgdiff.cc doesn't use the pthreads
API directly anymore. Rather, it uses the higher level "Workers
Queue" API provided by the abigail::workers namespace.
The main benefits are:
- better code readability and maintainability. The code base doesn't
have any global variable anymore. This is going to be helpful when
adding new features to the abipkgdiff.cc code base.
- faster code. The tests/runtestdiffpkg test program executes on ~
17s without the patch, and on ~ 11s with the patch on my old X220
laptop.
* tools/abipkgdiff.cc: Remove ftw.h, pthread.h, unistd.h, add
fts.h and abg-workers.h.
(verbose, elf_file_paths_tls_key, reports_map, env_map, map_lock)
(arg_lock, prog_options): Remove all these global variables.
(struct package_descriptor): Remove this type.
(pthread_routine_extract_package)
(first_package_tree_walker_callback_fn)
(second_package_tree_walker_callback_fn, pthread_routine_compare)
(pthread_join, pthread_routine_extract_pkg_and_map_its_content):
Remove these functions.
(options::{num_workers, verbose}): Define new data members.
(options::options): Initialize the new verbose and num_workers data members.
(package::erase_extraction_directory)
(erase_created_temporary_directories_parent): Take the program
options in parameter. Don't use the global verbose variable
anymore.
(package::erase_extraction_directories)
(erase_created_temporary_directories, extract_package): Take the
program options in parameter.
(extract_rpm, extract_deb, extract_tar): Likewise. And don't use
the global verbose variable anymore.
(compare): Don't use the global verbose variable anymore. Use the
new compare_task type along with the abigail::workers::queue type.
(pkg_extraction_task, pkg_prepare_task, compare_task)
(comparison_done_notify): Define new classes.
(maybe_update_vector_of_package_content): Define new static
function.
(create_maps_of_package_content): Don't take the ftw_cp_type
anymore. Don't use the global verbose variable anymore. Use the
fts_{open,read,close} functions, rather than the ftw one.
(extract_package_and_map_its_content): Don't use pthreads anymore.
Use the new pkg_extraction_task type created along with the
abigail::workers::queue type.
(prepare_packages): Don't use pthreads anymore. Use the new
pkg_prepare_task type along with the abigail::workers::queue type.
(elf_size_is_greater): Adjust to use
abigail::workers::queue::tasks, rather than the previous
compaer_args_sptr type.
(parse_command_line): Adjust to stop using the global verbose
variable.
(main): Remove use of global variables prog_options and also the
packages variable.
