[racket-dev] overwrite
When I use drracket, I frequently get a warning that my file has been modified on disk and the question of whether I want to save the file or revert. Is anyone else suffering from this problem? _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev

Re: [racket-dev] overwrite
Looking at the code, I don't see anything suspicious (assuming that after-save-file and file-or-directory-modify-seconds work properly, that is). If you find a way to make it happen (even if it only works 1 in 10 tries or something), that would help. Or if you had the energy to instrument the after-save-file method in the framework to tell what it is doing and watched those printsouts and compared them with reality that would be a lot of help.

Re: [racket-dev] overwrite
Dunno whether this helps... I haven't looked at the pertinent Racket code, but errors like this often happen in Unix applications because the mtime of the file is in the future relative to the current time clock. Less commonly, because the mtime changed since the file was read by the app or since the app last checked. The most common case can happen because a VC/CM system is updating the times (someone mentioned Git, and some other systems do this), because it's a network filesystem and the server and workstation clocks aren't synced sufficiently, or because NTP or some other mechanism dangerously jumped the current time clock in reverse (usually a good NTP daemon will slow the clock rather than jump in reverse).

One other note; if it's NTP, it would probably happen only on computers whose clocks tended to run a little fast or a little slow; this could explain why some of us have never seen this, and others see it all the time.

Re: [racket-dev] overwrite
Yes, that's it. Also, put something into the after-save-file-method: diff --git a/collects/framework/private/editor.rkt b/collects/framework/private/editor.rkt index 0c8981b..cb5504a 100644 --- a/collects/framework/private/editor.rkt +++ b/collects/framework/private/editor.rkt @@ -190,7 +190,8 @@ (set! last-saved-file-time (and filename (file-exists? filename) - (file-or-directory-modify-seconds filename) + (file-or-directory-modify-seconds filename)) +(log-warning (format "saved ~a at ~a" filename last-saved-file-time) (inner (void) after-save-file success?)) and then when you see this strange behavior, maybe it the particular numbers that you're seeing might shed some light on which part of this is going wrong.

NTP is unlikely to be the problem, since the times are saved on the filesystem, independently of the system time (or clock). And since Robby says that DrR compares only the time value regardless of being in the future, then there shouldn't be any problem with that. (It might, however, lead to problems if there's something that can change the file's time when it's in the future -- for example, if compiling the file tries to guarantee that it is not in the future for the compiled file to be further in time, and if DrR causes this by the automatic compilation. (This is not a guess about the problem, just an example of how it could break.)) As for git, it shouldn't lead to times in the future, since unlike other systems (like svn), it does not have a time stamp for each file. Instead, the idea is that it only changes files that it touches and uses the current time. This is why a rebase operation can lead to a lot of time changes -- since it will undo your commit(s), then fast-forward the repository, then replay the commits, so you end up with many files that have the same contents, but a different time. (And as an unrelated reminder -- if this bothers anyone, I have a wrapper that properly restores the time for such operations.) -- ((lambda (x) (x x)) (lambda (x) (x x))) Eli Barzilay: http://barzilay.org/ Maze is Life! _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
Re: [racket-dev] overwrite
Is this happening on network-mounted drives? One strange thing I've run into in the past is that on SMB-mounted filesystems, the timestamp is rounded off to a multiple of 2 seconds. It seems like that could cause this problem. rsync has a --modify-window parameter to accommodate this. e.g. see here: http://www.goodjobsucking.com/?p=16 _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev

I tried to save the file, and was informed that it had changed on disk since my last save from DrRacket, and did I want to overwrite it. Here's what I got last-saved-file-time: 1299611826 file-modified-time: 1299611832 These times are both quite close to when I tried to save. In retrospect, I should have added the output of (current-seconds) to the log output. I don't recall a six-second delay while trying to save.

How about also putting the filename into the log (the one that's being passed to file-or-directory-modify-seconds) and recording if it is the after-load-file or the after-save-file method that's updating the last-saved-file-time field?
