Summary: Linux version of LibreOffice locks open documents in a
way incompatible with MS Word
Severity: normal
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: Other
Status: UNCONFIRMED
Version: 4.0 all versions
Component: filters and storage
Product: LibreOffice
When I try to open a document in MS Word (run via Wine), having it open in
LibreOffice Writer, Word hangs. I've reported this to Wine [1]. The developer
answered:
> My guess is that the Linux version of LibreOffice locks the file

> range-locks the entire thing, while the Windows version uses
> CreateFile sharing semantics (not available on Linux).

So this also seems to affect real Windows-based Word when accessing file on a
network share. The Wine developer also suggests the following:
> LibreOffice could fix this by locking only bytes 0x7fffff93 through
> 0x7fffffe2. We're limited by the design decisions of MS, and I can't

> I'd be happy to discuss this further with LibreOffice devs.
