Yesterday I got to investigate why the unit tests for one of my projects didn't work anymore. The tests are collected by a short Perl program that scans all *.c files and generates the test structure. But... it didn't find some c files anymore :-o I can see them using "DIR", I can see them in Explorer and everywhere else, but Perl is completely oblivious to their existence.
It took a while to understand that I recently updated Cygwin and that this now hides "temporary" files by default. The thing is, this "temporary" flag on Windows is so obscure that there is no UI to set/unset it and even if it is set you usually don't notice it. Turns out my IDE sets the flag by accident, and did so for a decade, I just never noticed until now! It writes a temporary file and then renames that to the final name, without removing the flag... but whatever the reason, even Microsoft occasionally screws this up, apparently: https://social.technet.microsoft.com/Forums/windows/en-US/5d63a03a-f711-4035-a601-d66994c411eb/microsoft-print-to-pdf-troublesome-t-attribute?forum=win10itproapps TL;DR: Please roll back the change in fhandler_disk_file.cc, do not hide files that are otherwise completely visible in all other tools due to a flag that nobody knows about and that cannot be unset trivially, not even by Window's own ATTRIB command or Explorer.
