  50. 50. Package Model An update package is the bundled feature you want to install.
  51. 51. Package Structure <ul><li>An update feature is packaged as a zip </li><ul><li>A package descriptor file: package.xml.
  52. 52. An installation descriptor: install.xml.
  53. 53. The package data: </li><ul><li>JARs to install
  54. 54. configuration files and other resources to copy on the server. </li></ul><li>Descriptor files must reside in the ZIP root. </li></ul></ul>
  55. 55. The Package Descriptor <ul><ul><li>A Package is uniquely identified by its name and version.
  56. 56. A Package has a type and a set of properties required by the installer. </li></ul></ul>
  57. 57. Package Properties <ul><li>Main properties: </li><ul><li>Title – A title to be used in the UI.
  58. 58. Description – The package description
  59. 59. Vendor – the Vendor name
  60. 60. Platforms – a list of target platforms </li><ul><li>The target platforms limit the distributions where the package can be installed. </li></ul><li>Dependencies – a list of dependencies, if any. </li></ul></ul>
  61. 61. Package Dependencies <ul><li>A package may require some other packages to be installed before you install it. </li><ul><li>Dependencies are identified using the package ID – which has the format: 'name'-'version'.
  62. 62. Dependencies are transitive – in order to be able to install your package you must install all transitive dependencies. </li></ul><li>A special dependency are the target platforms. </li><ul><li>You cannot install a package on an unsupported platform. </li></ul></ul>
  63. 63. Package Install - Descriptor <ul><li>Installable artifacts: </li><ul><li>Nuxeo bundles (installed in bundles directory)
  64. 64. Local third party libraries (installed in Nuxeo 'lib' directory)
  65. 65. Global third party libraries (installed in container 'lib' directory)
  66. 66. Static resource files
  67. 67. Configuration files (installed in Nuxeo 'config' directory) </li></ul></ul>
  68. 68. Package Install - Example <ul><li>Use package variables to specify artifact locations. </li></ul>
  69. 69. Package Install - Variables <ul><li>In an install.xml you can use a set of useful variables like: </li><ul><li>Package related </li><ul><li>package.id, package.name, package version
  70. 70. package.root – the package root </li></ul><li>Environment
  71. 71. env.lib, env.bundles, env.config, env.syslib
  72. 72. sys.timestamp </li></ul><li>And also any Java System or Nuxeo Property </li></ul>
  73. 73. Studio Packages <ul><li>Studio provides integration with Update Center.
  74. 74. You can install a Studio generated plugin in one click from Admin Center! </li><ul><li>You can install either tagged versions either the working copy of the project. </li></ul><li>Studio Packages are hot deployable. </li><ul><li>No need to restart the server.
  75. 75. Refresh the browser to see the changes. </li></ul></ul>
  76. 76. Update System What happens when installing or uninstalling a package?
  77. 77. The Installation Process <ul><li>The package is validated to check if all conditions are met – dependencies are resolved and the install script is valid.
  78. 78. The installation starts – any user options are passed to install commands </li><ul><li>Each install rule is executed in the order it appear in the descriptor.
  79. 79. An install log is created by appending in the reverse execution order the commands that succeeded.
  80. 80. If install succeeds an uninstall.xml file is generated from the install log. </li></ul></ul>
  81. 81. Automatic Rollback <ul><li>Installation ensures that failures in an install task will not leave the system in an unknown state.
  82. 82. In case of a failure, an automatic rollback is done – and thesystem is reset to its initial state (the one before starting the installation).
  83. 83. The rollback mechanism executes all the commands present in the install log.
  84. 84. Rollback is also done if an uninstall fails. </li></ul>
  85. 85. The Uninstall Process <ul><li>The uninstall descriptor is auto-generated when an install succeeds from the install log.
  86. 86. At install time, a backup is made for any file replaced or removed by the installer.
  87. 87. Also an MD5 fingerprint is generated for any installed artifact.
  88. 88. At uninstall backups are restored but only if the MD5 of the target file match the one created by the installer. </li></ul>
  89. 89. Uninstall Descriptor
  90. 90. Hot Reload Support <ul><li>Limited hot reload after an install / uninstall is supported for some packages. </li><ul><li>Any Studio Packages
  91. 91. Any Package that doesn't contain Java code </li></ul><li>Hot reload will be improved to also support packages containing java classes in the near future. </li></ul>
  92. 92. What's Next? <ul><li>Project delivery through Marketplace
  93. 93. Install wizard improvements
  94. 94. Hot reloading improvements
  95. 95. Nuxeo Studio introspection of Marketplace packages
  96. 96. Commercial packages with e-payment </li></ul>
  97. 97. Thank you!
