We can do something more fancy on Mac, but it's more risky (I was developing this on Linux). I can add a TODO(phajdan.jr) to port the Mac logic here when I switch to the Mac checkout. we _have_ to do exactly what sqlite's vfs does (on linux _and_ on mac). otherwise, we'll end up with subtle bugs that will take months to debug. > > platform/sql/chromium/SQLiteFileSystemChromiumPosix.cpp:1090 > > sqlite3_vfs* unix_vfs = sqlite3_vfs_find("unix"); > We still need it for other things, like xDlError, xSleep, xCurrentTime, and so on. we should copy-paste + modify those too, and remove any references to the "unix" VFS: either we reuse as much of it as possible, or we don't use it at all. 281529 7 68080 phajdan.jr 2010-09-20 07:31:18 -0700 Created attachment 68080 patch Dumitru, thanks for review.

Just think there may ght be demand for use_system_sqlite=1, with reasons just like use_system_skia=1 and use_system_libjpeg, etc. Just read http://code.google.com/p/chromium/issues/detail?id=22208 and noticed that this is still a pending issue at chromium side. As the bug at chromium side is still open, I think we'd better also keep this one open if fixing at chromium side is not enough to fix the issue. 563850 23 michaeln 2012-02-23 19:42:48 -0800 > I just started to look at the issue, and haven't got much detail yet.

As the bug at chromium side is still open, I think we'd better also keep this one open if fixing at chromium side is not enough to fix the issue. Proceed with caution :) The presence of a change request in a tracking system does not mean there is a compelling reason to do it. The reason I'm probing for a justification is because resolving this has hair on it. Pawel was the motivating force for USE_SYSTEM_SQLITE for quite some time but has since dropped it (but only after some lengthy efforts). 574011 24 wangxianzhu 2012-03-08 11:34:10 -0800 (In reply to comment #20) > I'm sure we should reopen this bug, according to https://lists.webkit.org/pipermail/webkit-dev/2011-June/017169.html > > I'll work on this bug, fix the tsan reported racing issues.
