v3 v4 15 15 === 2. Update the Trac Code #UpdatetheTracCode 16 16 17 Get the new version as described in TracInstall, or your operating system specific procedure. 18 19 If you already have a 0.12 version of Trac installed via `easy_install`, it might be easiest to also use `easy_install` to upgrade your Trac installation: 20 21 {{{#!sh 22 easy_install --upgrade Trac==1.0 23 }}} 24 25 If you do a manual (not operating system-specific) upgrade, you should also stop any running Trac servers before the installation. Doing "hot" upgrades is not advised, especially on Windows ([trac:#7265]). 17 Get the new version as described in TracInstall, or through your operating system package manager. 18 19 If you already an earlier version of Trac installed via `easy_install`, it might be easiest to also use `easy_install` to upgrade your Trac installation: 20 21 {{{#!sh 22 easy_install --upgrade Trac==1.2 23 }}} 26 24 27 25 You may also want to remove the pre-existing Trac code by deleting the `trac` directory from the Python `lib/site-packages` directory, or remove Trac `.egg` files from former versions. … … 31 29 * on MacOSX: `/Library/Python/2.X/site-packages` 32 30 33 You may also want to remove the Trac `cgi-bin`, `htdocs`, `templates` and `wiki-default` directories that are commonly found in a directory called `share/trac`. The exact location depends on your platform. This cleanup is not mandatory, but makes it easier to troubleshoot issues later on, as your installation is uncluttered by code or templates from a previous release that is not used anymore. As usual, make a backup before actually removing things.31 You may also want to remove the directory in which your static resources are [TracInstall#cgi-bin deployed]. The exact location depends on your platform. This cleanup is not mandatory, but makes it easier to troubleshoot issues later on, as your installation is uncluttered by code or templates from a previous release that is not used anymore. As usual, make a backup before actually removing things. 34 32 35 33 === 3. Upgrade the Trac Environment #UpgradetheTracEnvironment … … 42 40 }}} 43 41 44 This command will do nothingif the environment is already up-to-date.42 This command will not have any effect if the environment is already up-to-date. 45 43 46 44 Note that a backup of your database will be performed automatically prior to the upgrade. 47 This feature is relatively new for PostgreSQL or MySQL databases, so if it fails, you will have to backup the database manually. Then, to perform the actual upgrade , run:45 This feature is relatively new for PostgreSQL or MySQL databases, so if it fails, you will have to backup the database manually. Then, to perform the actual upgrade: 48 46 {{{#!sh 49 47 trac-admin /path/to/projenv upgrade --no-backup … … 65 63 trac-admin /path/to/env deploy /deploy/path 66 64 }}} 67 this will extract static resources and CGI scripts (`trac.wsgi`, etc) from new Trac version and its plugins into `/deploy/path`. 65 66 This will extract static resources and CGI scripts (`trac.wsgi`, etc) from new Trac version and its plugins into `/deploy/path`. 68 67 69 68 Some web browsers (IE, Opera) cache CSS and Javascript files aggressively, so you may need to instruct your users to manually erase the contents of their browser's cache, a forced refreshed (`<F5>`) should be enough. … … 74 73 === 6. Steps specific to a given Trac version 75 74 75 ==== Upgrading from Trac 1.0 to 1.2 #to1.2 76 77 ===== Python 2.5 no longer supported 78 79 Upgrade Python to at least 2.6 or 2.7, but not 3.0 or greater. 80 81 ===== Obsolete Plugins 82 83 Trac has added functionality equivalent to the following plugins: 84 * [https://trac-hacks.org/wiki/AdminEnumListPlugin AdminEnumListPlugin] 85 * [https://trac-hacks.org/wiki/DateFieldPlugin DateFieldPlugin]: see the **time** [TracTicketsCustomFields#AvailableFieldTypesandOptions custom field type] 86 * [https://trac-hacks.org/wiki/GroupBasedRedirectionPlugin GroupBasedRedirectionPlugin]: the default handler can set as a user preference. 87 * [https://trac-hacks.org/wiki/LinenoMacro LinenoMacro]: see WikiProcessors#AvailableProcessors 88 * [https://trac-hacks.org/wiki/NeverNotifyUpdaterPlugin NeverNotifyUpdaterPlugin]: see [TracNotification#notification-subscriber-section notification subscribers] 89 * [https://trac-hacks.org/wiki/QueryUiAssistPlugin QueryUiAssistPlugin]: see TracQuery#Filters. 90 * [https://trac-hacks.org/wiki/TicketCreationStatusPlugin TicketCreationStatusPlugin]: see [#NewWorkflowActions] 91 92 The plugins should be removed when upgrading Trac to 1.2. 93 94 ===== New workflow actions #NewWorkflowActions 95 96 The ticket creation step is controlled with a workflow action. The default workflow has `create` and `create_and_assign` actions. The `create` action will always be added when upgrading the database. The `create_and_assign` action will be added if the workflow has an //assigned// state. You may want to edit your workflow after upgrading the database to customize the actions available on the //New Ticket// page. 97 98 ===== New permissions policy for read-only wiki pages 99 100 Since 1.1.2 the read-only attribute of wiki pages is enabled and enforced only when `ReadonlyWikiPolicy` is in the list of active permission policies. If `[trac] permission_policy` has the default value `DefaultPermissionPolicy, LegacyAttachmentPolicy`, then `ReadonlyWikiPolicy` should be automatically appended to the list when upgrading the environment: 101 {{{#!ini 102 [trac] 103 permission_policies = ReadonlyWikiPolicy, 104 DefaultPermissionPolicy, 105 LegacyAttachmentPolicy 106 }}} 107 108 If other permission policies are enabled, `trac.ini` will need to have `ReadonlyWikiPolicy` appended to the list of active `permission_policies`. See TracFineGrainedPermissions#ReadonlyWikiPolicy for additional details on the proper ordering. 109 76 110 ==== Upgrading from Trac 0.12 to Trac 1.0 #to1.0 77 111 78 112 ===== Python 2.4 no longer supported 113 79 114 Upgrade Python to at least 2.5, but not 3.0. 80 115 116 ===== Obsolete Plugins 117 118 Trac has added functionality equivalent to the following plugins: 119 120 * [https://trac-hacks.org/wiki/BatchModifyPlugin BatchModifyPlugin] 121 * [https://trac-hacks.org/wiki/GitPlugin GitPlugin] 122 * [https://trac-hacks.org/wiki/OverrideEditPlugin OverrideEditPlugin] 123 124 The plugins should be removed when upgrading Trac to 1.0. 125 81 126 ===== Subversion components not enabled by default for new installations 127 82 128 The Trac components for Subversion support are no longer enabled by default. To enable the svn support, you need to make sure the `tracopt.versioncontrol.svn` components are enabled, for example by setting the following in the TracIni: 83 129 {{{#!ini … … 85 131 tracopt.versioncontrol.svn.* = enabled 86 132 }}} 133 87 134 The upgrade procedure should take care of this and change the TracIni appropriately, unless you already had the svn components explicitly disabled. 88 135 89 136 ===== Attachments migrated to new location 137 90 138 Another step in the automatic upgrade will change the way the attachments are stored. Create a backup of the `attachments` directory before upgrading. In case the `attachments` directory contains some files which are //not// attachments, the last step of the migration to the new layout will fail: the deletion of the now unused `attachments` directory can't be done if there are still files and folders in it. You may ignore this error, but better to move them elsewhere and remove the `attachments` directory manually. The attachments themselves are now all located in your environment below the `files/attachments` directory. 91 139 92 140 ===== Behavior of `[ticket] default_owner` changed 141 93 142 Prior to 1.0, the owner field of new tickets always defaulted to `[ticket] default_owner` when the value was not empty. If the value was empty, the owner field defaulted to to the Component's owner. In 1.0 and later, the `default_owner` must be set to `< default >` to make new tickets default to the Component's owner. This change allows the `default_owner` to be set to an empty value if no default owner is desired. 94 143 … … 96 145 97 146 ===== Python 2.3 no longer supported 147 98 148 The minimum supported version of Python is now 2.4. 99 149 100 150 ===== SQLite v3.x required 151 101 152 SQLite v2.x is no longer supported. If you still use a Trac database of this format, you'll need to convert it to SQLite v3.x first. See [trac:PySqlite#UpgradingSQLitefrom2.xto3.x] for details. 102 153 103 154 ===== [trac:PySqlite] 2 required 155 104 156 [trac:PySqlite] 1.1.x is no longer supported. Please install 2.5.5 or later if possible, see [#Tracdatabaseupgrade Trac database upgrade] below. 105 157 158 ===== Obsolete Plugins 159 160 Trac has added functionality equivalent to the following plugins: 161 162 * [https://trac-hacks.org/wiki/AutoQueryPlugin AutoQueryPlugin] 163 * [https://trac-hacks.org/wiki/AdminConsoleProviderPatch AdminConsoleProviderPatch] 164 * [https://trac-hacks.org/wiki/AnchorMacro AnchorMacro]: see WikiFormatting#SettingAnchors 165 * [https://trac-hacks.org/wiki/TicketChangePlugin TicketChangePlugin]: see [TracPermissions#TicketSystem TICKET_EDIT_COMMENT permission] 166 * [https://trac-hacks.org/wiki/TicketDeletePlugin TicketDeletePlugin]: see `tracopt.ticket.deleter` 167 * [https://trac-hacks.org/wiki/SubversionLocationPlugin SubversionLocationPlugin]: see TracRepositoryAdmin#Repositories 168 * [https://trac-hacks.org/wiki/WikiCreoleRendererPlugin WikiCreoleRendererPlugin]: see [trac:WikiCreole] 169 * [https://trac-hacks.org/wiki/RepoRevisionSyntaxPlugin RepoRevisionSyntaxPlugin] (added in 0.12.1) 170 171 The plugins should be removed when upgrading Trac to 0.12. 172 106 173 ===== Multiple Repository Support 174 107 175 The latest version includes support for multiple repositories. If you plan to add more repositories to your Trac instance, please refer to TracRepositoryAdmin#Migration. 108 176 … … 118 186 119 187 ===== Improved repository synchronization 188 120 189 In addition to supporting multiple repositories, there is now a more efficient method for synchronizing Trac and your repositories. 121 190 … … 125 194 126 195 ===== Authz permission checking 196 127 197 The authz permission checking has been migrated to a fine-grained permission policy. If you use authz permissions (aka `[trac] authz_file` and `authz_module_name`), you must add `AuthzSourcePolicy` in front of your permission policies in `[trac] permission_policies`. You must also remove `BROWSER_VIEW`, `CHANGESET_VIEW`, `FILE_VIEW` and `LOG_VIEW` from your global permissions with `trac-admin $ENV permission remove` or the "Permissions" admin panel. 128 198 129 199 ===== Microsecond timestamps 200 130 201 All timestamps in database tables, except the `session` table, have been changed from "seconds since epoch" to "microseconds since epoch" values. This change should be transparent to most users, except for custom reports. If any of your reports use date/time columns in calculations (e.g. to pass them to `datetime()`), you must divide the values retrieved from the database by 1'000'000. Similarly, if a report provides a calculated value to be displayed as a date/time (i.e. with a column named "time", "datetime", "changetime", "date", "created" or "modified"), you must provide a microsecond timestamp, that is, multiply your previous calculation with 1'000'000. 131 202 132 203 ==== Upgrading from Trac 0.10 to Trac 0.11 204 133 205 ===== Site Templates and Styles 206 134 207 The templating engine has changed in 0.11 to Genshi, please look at TracInterfaceCustomization for more information. 135 208 … … 137 210 138 211 ===== Trac Macros, Plugins 212 139 213 The Trac macros will need to be adapted, as the old-style wiki-macros are not supported anymore due to the drop of [trac:ClearSilver] and the HDF. They need to be converted to the new-style macros, see WikiMacros. When they are converted to the new style, they need to be placed into the plugins directory instead and not wiki-macros, which is no longer scanned for macros or plugins. 140 214 141 215 ===== For FCGI/WSGI/CGI users 216 142 217 For those who run Trac under the CGI environment, run this command in order to obtain the trac.*gi file: 143 218 {{{#!sh … … 148 223 149 224 ===== Web Admin plugin integrated 225 150 226 If you had the [trac:WebAdmin] plugin installed, you can uninstall it as it is part of the Trac code base since 0.11. 151 227 152 228 ===== New Default Configurable Workflow 153 229 154 When you run `trac-admin <env> upgrade`, your `trac.ini` will be modified to include a `[ticket-workflow]` section. The workflow configured in this case is the original workflow, so that ticket actions will behave like they did in 0.10. 155 156 Graphically, that looks like this: 230 When you run `trac-admin <env> upgrade`, your `trac.ini` will be modified to include a `[ticket-workflow]` section. The workflow configured in this case is the original workflow, so that ticket actions will behave like they did in 0.10: 157 231 158 232 {{{#!Workflow width=500 height=240 … … 176 250 There are some significant caveats in this, such as accepting a ticket sets it to 'assigned' state, and assigning a ticket sets it to 'new' state. So you will probably want to migrate to "basic" workflow; [trac:source:trunk/contrib/workflow/migrate_original_to_basic.py contrib/workflow/migrate_original_to_basic.py] may be helpful. See TracWorkflow for a detailed description of the new basic workflow. 177 251 178 ===== Global Configuration179 In versions prior to 0.11, the global configuration was by default located in `$prefix/share/trac/conf/trac.ini` or `/etc/trac/trac.ini`, depending on the distribution. You may want to specify that file to inherit from when upgrading. Literally, when upgrading you have to add an `[inherit]` section to your project's `trac.ini` file. Additionally, you have to move your customized templates and common images from `$prefix/share/trac/...` to the new location.180 181 252 === 7. Restart the Web Server #RestarttheWebServer 182 253 … … 197 268 198 269 === Wiki Upgrade 270 199 271 `trac-admin` will not delete or remove default wiki pages that were present in a previous version but are no longer in the new version. 200 272 … … 204 276 205 277 === Parent dir 278 206 279 If you use a Trac parent env configuration and one of the plugins in one child does not work, none of the children will work. 207 280 … … 218 291 === Changing Database Backend 219 292 220 The [http ://trac-hacks.org/wiki/TracMigratePlugin TracMigratePlugin] on [http://trac-hacks.org trac-hacks.org] has been written to assist in migrating between SQLite, MySQL and PostgreSQL databases.293 The [https://trac-hacks.org/wiki/TracMigratePlugin TracMigratePlugin] on [https://trac-hacks.org trac-hacks.org] has been written to assist in migrating between SQLite, MySQL and PostgreSQL databases. 221 294 222 295 === Upgrading from older versions of Trac #OlderVersions
