Closed Bug 757351 Opened 7 years ago Closed 7 years ago
Sync uses deprecated octal literals
Not sure if it can be useful, but chrome workers now have access to a global object OS.Constants.libc that defines S_IRGRP, S_IROTH, S_IRUSR, S_IRWXG, S_IRWXO, S_IRWXU, S_IWGRP, S_IWOTH, S_IWUSR, S_IXOTH, S_IXGRP, S_IXUSR.
Yoric: do you have an MDN link for OS.Constants.libc? I can't seem to find it...
Here is the source: http://dxr.lanedo.com/mozilla-central/dom/system/OSFileConstants.cpp.html. But, it doesn't appear that OS is defined in the main chrome thread (opened web console from about:about). So, I don't think Sync will be able to use these constants :(
No MDN doc yet. And yes, it is defined only in worker threads. I will add support for main thread once I have started working on main-thread OS.File, but for the moment, it was deemed too early. There is a bug for exporting it to the main thread, though (bug 750178). If you need these constants in the main thread, though, I can reprioritize that bug.
OK. Let's wait until bug 750178 is complete and then we'll tackle this. Removing mentored bug flags until we are unblocked.
Depends on: 750178
Whiteboard: [good first bug][mentor=gps][lang=js]
Maybe we're conflating two separate systems. FileUtils provides convenient and canonical ways to do File I/O with XPCOM. Yoric's stuff seems different from that. Since browser/base/content/sync/utils.js uses the XPCOM way, I think it should just use FileUtils, unless the proposal is to convert it to Yoric's system.
Indeed, looks like FileUtils is the right way to go. My work on OS.File (and OSFileConstants.cpp) is designed to eventually render FileUtils obsolete, but this might take some time.
Yoric: What's the state of OS.File these days?
sync triage: We think this should wait on yoric's work. Yoric, if that is still going, what's the bug to depend on?
Splendid! This should be relatively easy to tackle. The offending file in the source tree is browser/base/content/sync/utils.js.
I'll tackle this if nobody minds. I'm new here, and if I'm doing something wrong, please tell me!

You're doing everything right so far :) You'll want to read this, at the very least, and probably more besides if you're not already familiar with contributing to the Mozilla codebase. https://developer.mozilla.org/docs/Mercurial_FAQ#How_can_I_generate_a_patch_for_somebody_else_to_check-in_for_me.3F More: https://developer.mozilla.org/docs/Developer_Guide Either :gps or myself (:rnewman) is a great value to put in the reviewer field when you get that far, and we're here to offer advice if you need it. You can also ping one of us in #sync on IRC. Keep us posted of your progress!
Heh, Josh mid-aired me.

epiary: are you still working on this? If not, please update bug metadata appropriately. Thanks!
Aha, whoops! Looks like I put this off for some time now and forgot about it. I'll work on it some time these next few weeks, and by the end of that period I'll either finish or unassign myself.
Any news, epiary?
Alas, no, sorry to disappoint. I'm going to remove my status as assignee.
Just wonder how to reproduce this warning
I would like to contribute to this bug. I read the comments but wasnt able to draw some notable idea from it. It would be great if I am given a clear picture of what the bug is. 1. On IRC, the mentor told me that the offending line is | stream.init(fp.file, -1, 0600, 0); | in utils.js 2. Do i need to study the entire code of utils.js or only some part. Currently I have messed with my mercurial, it seems i need to pull a fresh copy. So it may take some time to start off. I will be updating the status here time to time.
(In reply to Amod [:greatwarrior] from comment #21) > 1. On IRC, the mentor told me that the offending line is | > stream.init(fp.file, -1, 0600, 0); | in utils.js Yes. The issue is the "0600" on that line. Unfortunately, per <https://developer.mozilla.org/en-US/docs/PR_Open#Parameters> the constants you want -- (PR_IRUSR | PR_IWUSR) -- aren't available from JS. OS.Constants exposes them (S_IRUSR | S_IWUSR), but unless this file already has access to OS.Constants, we shouldn't introduce a dependency just for this. So if OS.Constants is already in scope, great; use those. If not, introduce a constant "PERMISSIONS_RWUSR" defined as 0x180. I'm marking this bug as a dependency of Bug 433295, which is essentially "you can't use these constants from JS". If OS.Constants is now widely available, including in this scope, perhaps we can dupe that bug to the landing bug for OS.Constants. (Yoric?) > 2.

On the main thread, OS.Constants is not (and probably never will be) automatically in the scope. You need to import it with Components.utils.import("resource:///gre/modules/osfile.jsm"); On worker threads, OS.Constants is in the default scope.

Is the header correct ? especially : Bug 757351 - Sync uses deprecated octal literals; r=rnewman Since I am new here, I am not much used to patch headers. So I apologize for any mistake.
