  "message": "Test the progress display\n\n\u0027progress.c\u0027 has seen a few fixes recently [1], and, unfortunately,\nsome of those fixes required further fixes [2].  It seems it\u0027s time to\nhave a few tests focusing on the subtleties of the progress display.\n\nAdd the \u0027test-tool progress\u0027 subcommand to help testing the progress\ndisplay, reading instructions from standard input and turning them\ninto calls to the display_progress() and display_throughput()\nfunctions with the given parameters.\n\nThe progress display is, however, critically dependent on timing,\nbecause it\u0027s only updated once every second or, if the toal is known\nin advance, every 1%, and there is the throughput rate as well.  These\nmake the progress display far too undeterministic for testing as-is.\nTo address this, add a few testing-specific variables and functions to\n\u0027progress.c\u0027, allowing the the new test helper to:\n\n  - Disable the triggered-every-second SIGALRM and set the\n    \u0027progress_update\u0027 flag explicitly based in the input instructions.\n    This way the progress line will be updated deterministically when\n    the test wants it to be updated.\n\n  - Specify the time elapsed since start_progress() to make the\n    throughput rate calculations deterministic.\n\nAdd the new test script \u0027t0500-progress-display.sh\u0027 to check a few\nsimple cases with and without throughput, and that a shorter progress\nline properly covers up the previously displayed line in different\nsituations.\n\n[1] See commits 545dc345eb (progress: break too long progress bar\n    lines, 2019-04-12) and 9f1fd84e15 (progress: clear previous\n    progress update dynamically, 2019-04-12).\n[2] 1aed1a5f25 (progress: avoid empty line when breaking the progress\n    line, 2019-05-19)\n\nSigned-off-by: SZEDER Gábor \u003cszeder.dev@gmail.com\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
