    Move dubious file: -> smb: conversion from INetURLObject to file UCP · 46c645bf
    Stephan Bergmann yazdı
    The Linux-only conversion of file URLs with a non-empty (other than "localhost")
    authority to smb URLs had been added in 2010 with
    0b9ef81b "tools-urlobj-smb-scheme-patch.diff:
    migrated" (applying a Go-oo patch?) but giving no rationale beyond "process
    relative SMB paths (in hyperlinks) correctly".  That makes it hard to tell
    whether that patch is (still) actively useful for anything, or was just a
    misguided hack from the beginning:
    
    * Why make this Linux only?  What about other non-Windows OSs?  (On Windows,
      such URLs can be resolved as UNC pathnames.)  If the reason for Linux-only was
      that it is the only OS where LO can handle smb URLs via GIO, why not make it
      conditional on ENABLE_GIO?
    
    * Why map to smb?  There are various remote file access protocols.  Hardcoding
      smb looks arbitrary here.
    
    Anyway, INetURLObject is arguably at a wrong level for such a patch.  To not
    drop the hack wholesale, reimplement it in the file UCP, forwarding to a
    potential other UCP that can handle smb URLs any file://<host>/... URLs
    (rewritten as smb URLs) that the file UCP cannot handle itself.
    (file://localhost/... URLs will already have been normalized to file:///... by
    INetURLObject when they reach the file UCP, and even if they were not, the
    osl/file.hxx functionality underlying fileaccess::TaskManager::getUnqFromUrl
    knows how to handle them, so they will not take the forward-to-smb code branch.)
    
    (The corresponding #ifdef WIN code from 0b9ef81b
    has already been removed with 82034b04
    "tdf#119326 crash when adding "Windows Share" File resource".)
    
    (I came across that 2010 patch while looking into
    <https://bugs.documentfoundation.org/show_bug.cgi?id=107461> "Does not support
    'file://' scheme with actual hostname".  A next step would be to make the file
    UCP actually handle any file://<host>/... URLs that denote the local host.)
