2021-03-16Lots of performance tuning of native Linux implementation, but still 5-10% ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
slower than libdispatch.
2021-03-16Simplify non-native-Linux implementation. Appears to make little difference ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
to benchmarks.
2021-03-16Add benchmark results for GCD on Linux, Win32 thread pools on Windows, and ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
ASIO on both Linux and Windows. My native implementation is overcreating threads currently, so not worth recording those yet.

2021-03-16Finally got a fully working native implementation on Linux. I had realised ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
that attempting to fix this each morning before work was turning into never actually making progress, so I carved out four hours this morning without distraction, and boom here we go. I next need to simplify this implementation, it has become bloated with all the changes, it definitely could be made much leaner.

dynamic_thread_pool_group, but still not working quite right yet.
2021-03-16Dynamic scaling within native Linux implementation of ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
dynamic_thread_pool_group is somewhat working now, but it's not working quite right yet.
2021-03-16Implement thread enumeration for Linux native dynamic_thread_pool_group.Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
2021-03-16Make the dynamic thread pool work scheduling not quite as strict in the ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
native Linux implementation, now we only examine higher priority groups once per group cycle. This produces behaviours much more consistent with the Win32 thread pool and Grand Central Dispatch.
2021-03-16wip native linux threadpool implementation for dynamic_thread_pool_group.Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
2021-03-16Hopefully fix failure to find libdispatch on Mac OS. Also hopefully fix test ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
failure on Windows.
2021-03-16Implemented and debugged a Grand Unified Dispatch backend for ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
dynamic_thread_pool_group. Works surprisingly nicely on Linux, haven't actually tested it on Mac OS nor FreeBSD, but no reason it shouldn't work just fine.
2021-03-16Implement dynamic_thread_pool_group::io_aware_work_item.Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
2021-03-16Add unit test to ensure nested dynamic thread pool groups work as expected. ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
Still Windows only implementation.
2021-03-16wip dynamic_thread_pool_group, so far has Windows support only. Note that ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
LLFIO now hard requires Windows 7 rather than Vista.
2021-03-16Add statfs_t::f_iosinprogress and statfs_t::f_ioswaittime whichNiall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
can be used to monitor how congested the underlying hardware device for a handle is.
2021-03-15Fix inability to open directory junctions on Windows using `symlink_handle` ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
(issue #73).

2021-03-08Suppress warning on Linux.Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
2021-03-06Fix lots of bugs due to newer kernel 5.8 in Ubuntu 20.04, and OpenZFS v0.8:Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
1. clone_extents_to() didn't handle partial clones, and now it does. 2. OpenZFS has a bug in SEEK_DATA which caused empty clones, we use a hacky workaround to fix it. 3. mapped_file_handle now fails loudly if it fails to allocate the map due to VMA exhaustion. This closes off a ton of unpleasant surprise in heavily loaded applications. 4. If your Linux kernel was old enough, or you are on ZFS, renaming a mapped_file_handle caused internal state corruption which led to lots of bad things, including `bad_file_descriptor` errors. 5. On Windows, renaming a mapped_file_handle now tears down and restores the maps, as you cannot rename a file with open maps.
2021-02-23Fix breakage caused by upstream changes to quickcpplib. De-CRLF cached ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
filelist files.
2021-02-17mapped_file_handle::read() and write() was not detecting when VA space had ↵Niall Douglas (s [underscore] sourceforge {at} nedprod [dot] com)
been exhausted, and was incorrectly segfaulting the process rather than returning errc::not_enough_memory.
