Each call to fwrite() 2020-08-06T22:17:04Z Carl Hetherington cth@carlh.net 2020-08-06T22:11:38Z urn:sha1:6c685e0cd6143dd7a8b1a9b5631b1bc9c0c4d687 writes a few (often around 4) blocks of (I think) directory data to the drive, so if you only fwrite() one block it ends up writing 1 block of "payload" and 4 blocks of "admin". Using bigger blocks makes it faster; an even bigger block than this makes it a little faster still, but not significantly. The extra block writing is seemingly triggered by fwrite() calling ext4_block_cache_write_back(..., 0). A better fix is probably to call this another way, at the end of the file copy. Check that we have a connection to the disk writer before starting to use it in earnest. 2020-08-06T22:10:59Z Carl Hetherington cth@carlh.net 2020-08-06T22:10:59Z urn:sha1:334d3cb564c72bd430a17c6e6f01aeb488fb191c Fix some unused variable warnings on macOS. 2020-07-27T09:05:08Z Carl Hetherington cth@carlh.net 2020-07-27T09:05:08Z urn:sha1:99c1d1f247343b884af0b51389311484ed265d3b Various OSX warnings fixes. 2020-07-26T19:30:59Z Carl Hetherington cth@carlh.net 2020-07-26T19:29:43Z urn:sha1:6eba051dcbb8c56e3e2efea946ce0380d17a7b33 Update deprecated method call. 2020-07-26T19:30:59Z Carl Hetherington cth@carlh.net 2020-07-26T17:41:41Z urn:sha1:2370c03b83e1a074c6b7362885e69bc364553e49 Do all writes then do all verification and report progress 2020-05-02T22:41:24Z Carl Hetherington cth@carlh.net 2020-05-02T22:41:24Z urn:sha1:9bdf75cc619740246c2c413d204f26e228e75bb1 for each separately (#1743) Try to start _writer on-demand on macOS (#1739). 2020-05-02T19:37:14Z Carl Hetherington cth@carlh.net 2020-05-02T19:37:14Z urn:sha1:3a715c7e0d5cbb39ffd6816899ef3050e8331882 Add git commits to writer log files. 2020-04-30T18:07:46Z Carl Hetherington cth@carlh.net 2020-04-30T18:07:46Z urn:sha1:3ee6f2e6ee3682fd1eebfd15c2d61588587e7096 Turn on lwext4 debugging to see if that helps. 2020-04-30T14:59:49Z Carl Hetherington cth@carlh.net 2020-04-30T14:59:49Z urn:sha1:4c435d735b010929dfb222e2da0cf90205e6a6c1 Missed part of rdisk -> disk revert. 2020-04-29T23:25:52Z Carl Hetherington cth@carlh.net 2020-04-29T23:25:52Z urn:sha1:2a3ba951af6da9f3e9770e971ceb07025090cef1
