905509 - [OS.File] OS.File needs a way to change the modified time of a file.

Status: RESOLVED DUPLICATE of bug 924916

(Toolkit Graveyard :: OS.File, defect)

Description

[Mark Hammond [:markh] [:mhammond]]

Bug 897880 introduced a requirement to "touch" a file using OS.File, but there's no OS.File way to achieve this.  That bug introduces a nasty hack to achieve it, but we'd like to replace it with something sane.  As it needs to do it in a ChromeWorker, there's no access to nsIFile either.

(It might make sense to make more of the "stat" object writable, but I'll initially keep this bug to the narrow scope needed by bug 897880)

I have browsed quickly the source code of GNU touch and it seems to simply open for append then close. Barring any mistake, this is exactly your nasty hack of bug 897880. I suspect that we can't do any better under Windows, either.

I actually tried that in bug 897880 but couldn't make it work.  As checked in, that bug reads 1 byte from the file and writes it back.  It may be that I did something wrong though.
