Deep dive into feature versioning in SharePoint 2010

  1. 1. Deep dive into feature versioning and upgrade support in SharePoint 2010<br />Jeremy Thake<br />
  2. 2. Jeremy Thake <br />Enterprise Architect since April ’11 at AvePoint<br />SharePoint MVP since July ’10<br />Co-Founder of<br />Speaker at MS TechEd 2009/10, SPC 11<br /><br /> @jthake<br />

  7. 7. Some easier than others<br />Definition vs. Instance<br />Site Column <Field><br />SPSite, SPWeb<br />Content Type <ContentType> <br />SPSite, SPWeb, SPList<br />Web Part <WebPart> <br />WP Gallery, Instances on pages<br />List Template<br />SPSite, SPWeb, Instances at SPWeb<br />
  8. 8. Some easier than others<br />Module (Page Layout, Master Page, Style sheets)<br />As long as not ‘customised’<br />Renaming files<br />
  9. 9. “OLD SKOOL”<br />Imperative in-place upgrade<br />Deactivate/Activate -> “if column missing add it”<br />Deactivate/Retract/Remove/Add/Deploy/Activate<br />Won’t work if in USE!<br />Field<br />Content Types – blocks delete<br />Web Parts out of gallery and Web Part Instances<br />List Templates – removes but breaks List instances<br />Workflow – removes assembly, breaks Workflow instances<br />New Feature - Stapling<br />PowerShell<br />

  15. 15. Upgrading features declaratively<br />Version attribute not just for show ;-)<br />Not set by default in XML so uses<br />ActivationDependencies can specify version<br />UpgradeActions element<br />VersionRange with Begin & End versions<br />MinimumVersion<br />ApplyElementManifest<br />AddContentTypeField<br />MapFile<br />
  16. 16. Upgrading Features Declaratively<br />DEMO<br />
  17. 17. AddContentTypeField<br />Add Columns to ContentType<br />
  18. 18. ApplyElementManifests<br />Integrated new artefacts into existing feature<br />E.g. New Fields in a Content Type<br />
  19. 19. Mapfile<br />Repoint a file to a new location on filesystem<br />E.g. renaming/relocating a deployed style sheet<br />Uncustomised files only<br />
  21. 21. Upgrading Feature Instances<br />DEMO<br />
  22. 22. Code ran<br />update-spsolution -identity SharePointProject.wsp-literalpathbinDebugSharePointProject.wsp –GACDeployment<br />
  23. 23. Powershell<br />get-spfeature | where {$_.DefinitionId -eq '7cd284c9-b998-457b-b782-4473744b7daf' }<br />| select DisplayName, Version<br />(get-spweb http://sp2010rtm:99/).Features | where {$_.DefinitionId -eq '7cd284c9-b998-457b-b782-4473744b7daf' }<br />psconfig -cmd upgrade -inplaceb2b<br />$site = get-spsite http://siteurl<br />$enabledfeature = $site.Features | where {$_.DefinitionId -eq '7cd284c9-b998-457b-b782-4473744b7daf' }<br />if($enabledfeature)<br />{<br /> $enabledfeature.Upgrade($false)<br />}<br />
  24. 24.
  25. 25. Upgrade actions Imperative<br />Provide assembly & class in UpgradeActions<br />CustomUpgradeActionss element provides Name and Parameters<br />Fires FeatureUpgrading event receiver<br />
  26. 26. Upgrading Features Imperatively<br />DEMO<br />
  29. 29.
  30. 30. TIPS<br />Don’t forget to change definition as well do upgrade<br />ALWAYS quit PowerShell when rebuilding WSP<br />Or use different names for WSP<br />If CustomUpgradeAction fails, doesn’t upgrade feature<br />Will leave things “half baked” – defensive coding<br />Adjust ULS logs to see messages<br />‘Feature Infrastructure’, ‘Fields’, ‘General’<br />
  31. 31. What to watch - Definitions<br />Copy definition, create new one, hide old version<br />List Templates<br />Workflow<br />Site Definitions<br />or Feature stapling<br />
  32. 32. What to watch - instances<br />Web Parts<br />Imperatively modify properties<br />Assembly upgrade<br />List Instances<br />Incrementally upgrade<br />Workflows<br />Assembly upgrade on existing activities<br />Changing what activities exist on current instances<br />“You’re on your own soldier”<br />
  33. 33. SANDBOXED SOLUTIONS<br />Slightly different!<br />Upgrade button for Sandboxed Solutions<br />On upgrading a Solution<br />All Features are upgraded automatically!<br />
  34. 34. Solution version<br />Defined by having new wsp name <br />e.g. SPDevWiki_v1.0.0.0.wsp and SPDevWiki_v2.0.0.0.wsp<br />Sandboxed Solutions<br />Deploying different versions to different Site Collections in Farm<br />Supported in Farm Solutions<br />Easy way to identify what version in different Farms <br />no other way of identifying solutions<br />only keeps most recent<br />
  35. 35. Assembly versions<br />New Assembly Version<br />Workflow instances + Web Part instances<br />Will remove old version from GAC breaking old Web Parts<br />Use Binding Redirect if not worried about old assembly version – if so why do it in the first place?<br />Assembly Versioning broken in Sandboxed Solutions<br />
  36. 36. Feature upgrade object model<br />QueryFeatures method (4 overloads)<br />GuidfeatureId<br />GuidfeatureId, boolneedsUpgrade<br />GuidfeatureId, Version featureVersion<br />SPFeatureScope scope, boolneedsUpgrade<br />Available from SPWebService(Farm), SPWebApplication, SPContentDatabase & SPSite<br />
  37. 37. Versioning strategies<br />Main Goal<br />Identify which versions are across farm<br />Assembly version and Feature versions will diverge<br />Release notes needed!<br />Stick with one approach<br />Major.Minor.Build.Revision<br />Change severity (breaking/major/minor)<br />Shipping/non-shipping (product orientated)<br />Incorporate sprint/iteration<br />Incorporate changeset number<br />Other crazy approaches!<br />
  38. 38. How can I prepare 2007 code?<br />Start versioning your features – default<br /><SharePoint:UIVersionedContentUIVersion=“4”><br />Deprecated API’s<br />Binding redirects<br />VSeWSS -> VS2010 supported<br />WSPBuilder/STSDev/STSADM/custom -> manual<br />
