[Bug 37202] New: MSWord hangs on opening a document opened in other program
https://bugs.winehq.org/show_bug.cgi?id=37202 Bug ID: 37202 Summary: MSWord hangs on opening a document opened in other program Product: Wine Version: 1.7.24 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ole32 Assignee: wine-bugs(a)winehq.org Reporter: b7.10110111(a)gmail.com Created attachment 49455 --> https://bugs.winehq.org/attachment.cgi?id=49455 Backtrace from winedbg. Process stopped by Ctrl+C after hanging. How to reproduce: 1. Have a .doc file 2. Open it in LibreOffice 3. Try opening it from MS Word 4. See Word hang 5. Close LibreOffice 6. See file finally opened in MS Word, it's no longer hung As I've tested similar scenario in a virtual machine, there Word gives a dialog saying that the file is locked for reading by another process. It's a regression: 65887802c502c4eeeb3fc905990e3e2f4548a482 is the first bad commit commit 65887802c502c4eeeb3fc905990e3e2f4548a482 Author: Vincent Povirk <vincent(a)codeweavers.com> Date: Fri Apr 18 16:37:56 2014 -0500 ole32: Initial storage file locking implementation. :040000 040000 b86f27a6f6561d9f35fd01166388e2e7a0380c28 68646bad80d38b40a014cb1cbd57b62aa19abad2 M dlls The hang occurs in NtDelayExecution called by NtLockFile (see attached backtrace). -- Do not reply to this email, post in Bugzilla using the above URL to reply.

My guess is that the Linux version of LibreOffice locks the file differently from the Windows version. The Linux version probably range-locks the entire thing, while the Windows version uses CreateFile sharing semantics (not available on Linux). You should see the same behavior as your Windows VM, if you run the Windows version of LibreOffice and Word in the same Wine prefix. You may be able to see the broken behavior without involving Wine, if you run Linux LibreOffice and Word on real Windows, by putting the shared file on a network share (but it depends on how the file share protocol maps those locking operations). In my testing, Windows does hang when opening a storage file, if byte 0x7fffff92 is locked. This is necessary to implement the rich locking semantics (see http://source.winehq.org/source/dlls/ole32/storage32.h#0504) of ole storage based on range locking. LibreOffice could fix this by locking only bytes 0x7fffff93 through 0x7fffffe2. We're limited by the design decisions of MS, and I can't think of a way that we could implement the Windows API correctly while dealing with another program that range-locks the entire file. I'd be happy to discuss this further with LibreOffice devs. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=37202 --- Comment #2 from Ruslan Kabatsayev <b7.10110111(a)gmail.com> --- Indeed, it works with Windows version of LibreOffice as expected. But if I run LibreOffice and Word from different wine prefixes, the locks seem to not work at all, i.e. file is freely opened by Word, as before the commit. Is it intended? Also, should I file a bug report to LibreOffice? (I guess it'd count as "enhancement" there, not a "bug", right?) -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=37202 --- Comment #3 from Vincent Povirk <madewokherd(a)gmail.com> --- The issue with separate prefixes is unfortunately a limitation of Wine: CreateFile sharing semantics don't exist on Linux, and so we have to implement them in wineserver, meaning they only work within the same prefix. Multiple instances of Word in separate prefixes (including over network shares with Windows, if range locking works on the network filesystem) should work correctly, because of the change that caused this bug. Please file a LibreOffice bug and CC me. It's debatable whether they're really doing anything wrong (though I would argue that they have to be prepared to interact with Windows programs over a network share, and what they're currently doing could break that), so enhancement seems appropriate, but I don't think we can fix it on our end. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=37202 --- Comment #5 from Vincent Povirk <madewokherd(a)gmail.com> --- I closed the LibreOffice bug because apparently Word on Windows can cope with an entire file range-locked for writing somehow. So this should be fixable in Wine, somehow. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
https://bugs.winehq.org/show_bug.cgi?id=37202 --- Comment #6 from Vincent Povirk <madewokherd(a)gmail.com> --- Word on Windows seems to cope with this OK (fails after ~2 seconds), but the storage API's my commit modified do not (they fail on Windows after ~20 seconds). -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=37202 --- Comment #7 from Vincent Povirk <madewokherd(a)gmail.com> --- Well, I can't figure out how Word is able to detect this situation in 2 or 0 seconds, when in my own testing with StgOpenStorage it takes 20 seconds to fail, and Word doesn't seem to be doing anything special. I guess I can add the 20 second timeout (which I suspect will mean a 40 second hang in Word, because that's what happens in Word on Windows if I set a read-only lock for the entire file), or I can use read locks to test for this situation in a way that should be compatible with Windows but that I know isn't what Windows does. I guess I'll try both and see what happens. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
