From 244fbe1460ffa77647468d97b4d8e7e79d7579bf Mon Sep 17 00:00:00 2001 From: Neil McErlean Date: Wed, 5 Jan 2011 14:16:59 +0000 Subject: [PATCH] Merge from V3.4 to HEAD. Fix for ALF-6192. r24622 Fix for ALF-6192 alfresco share could not delete file with preview. This issue was ultimately caused by the incorrect use of a BeforeDeleteNode policy. As a workaround to ALF-4119 a beforeDeleteNode policy was defined in RenditionAspect.java. This policy ensured that when path/template-based renditions were deleted, that the parent-child association to the source node, which is a non-primary association, was removed. In doing so, future calls to renditionService.getRenditions() would not return renditions from the archive store. However, this led to the permissions problem observed in this issue. It is possible that running the BeforeDeleteNode policy as system could have resolved the problem. However an alternative workaround for the deleted renditions problem has been implemented. The policy has been removed and instead, the RenditionService filters the results. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@24690 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261 --- .../alfresco/rendition-services-context.xml | 5 - .../repo/rendition/RenditionAspect.java | 116 ------------------ .../repo/rendition/RenditionServiceImpl.java | 24 ++++ .../RenditionServiceIntegrationTest.java | 15 ++- 4 files changed, 33 insertions(+), 127 deletions(-) delete mode 100644 source/java/org/alfresco/repo/rendition/RenditionAspect.java diff --git a/config/alfresco/rendition-services-context.xml b/config/alfresco/rendition-services-context.xml index 755ebbe7b7..d5cb354cb4 100644 --- a/config/alfresco/rendition-services-context.xml +++ b/config/alfresco/rendition-services-context.xml @@ -169,11 +169,6 @@ - - - - - diff --git a/source/java/org/alfresco/repo/rendition/RenditionAspect.java b/source/java/org/alfresco/repo/rendition/RenditionAspect.java deleted file mode 100644 index d704fb0508..0000000000 --- a/source/java/org/alfresco/repo/rendition/RenditionAspect.java +++ /dev/null @@ -1,116 +0,0 @@ -/* - * Copyright (C) 2005-2010 Alfresco Software Limited. - * - * This file is part of Alfresco - * - * Alfresco is free software: you can redistribute it and/or modify - * it under the terms of the GNU Lesser General Public License as published by - * the Free Software Foundation, either version 3 of the License, or - * (at your option) any later version. - * - * Alfresco is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
