DOCUMENT:Q237804 01-MAY-2001 [ssafe] TITLE :BUG: Deploying Shadow Files to a Live Web Site Fails PRODUCT :Microsoft SourceSafe PROD/VER:WINDOWS:5.0,6.0; winnt:4.0 OPER/SYS: KEYWORDS:kbinterop kbInternet kbSSafe500bug kbSSafe600bug kbIIS kbGrpDSSSafe kbiis400bug ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual SourceSafe for Windows, versions 5.0, 6.0 - Microsoft Internet Information Server 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Files shadowed to a live Web site don't get updated. You may not get any error messages or you may get: Error "File is already open" CAUSE ===== IIS 4.0 caches files to speed up Web requests. This caching keeps the file open for a period of 30 to 60 seconds. During this time, if a shadow occurs, that file is locked and cannot be updated. RESOLUTION ========== This issue will be resolved in the next major release of IIS version 5.0. STATUS ====== Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. MORE INFORMATION ================ This problem occurs because IIS 4 locks the file open in the Web browser. The shadow command cannot write to the file because the file has a handle already open. If the shadow command is attempted 60 seconds later, it will succeed. Steps to Reproduce Behavior --------------------------- 1. In the Visual SourceSafe Administrator, create a shadow folder for any Visual SourceSafe project that is a Web site on an IIS 4.0 server. Select the Set read-only flag for all files checkbox. 2. Shadow files to the Web site. 3. Open one of the shadowed files in a Web browser through the URL, like "http://webserver/test.htm". 4. Check out and edit that file in Visual SourceSafe using any editor, such as Microsoft Notepad. 5. Check the file back in.
