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 |
| 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. |

43 | 41 | |
44 | | This command will do nothing if the environment is already up-to-date. |
45 | | |
46 | | 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: |
48 | | {{{#!sh |
49 | | trac-admin /path/to/projenv upgrade --no-backup |
50 | | }}} |
| 42 | This command will not have any effect if the environment is already up-to-date. |

61 | 55 | === 5. Refresh static resources |
62 | 56 | |
63 | | If you have set up a web server to give out static resources directly (accessed using the `/chrome/` URL) then you will need to refresh them using the same command: |
| 57 | If you have configured your web server to serve static resources directly (accessed using the `/chrome/` URL) then you will need to refresh them using the [TracInstall#MappingStaticResources same command]: |

66 | 60 | }}} |
67 | | this will extract static resources and CGI scripts (`trac.wsgi`, etc) from new Trac version and its plugins into `/deploy/path`. |
68 | | |
69 | | 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 | 71 | === 6. Steps specific to a given Trac version |
75 | 72 | |
| 73 | ==== Upgrading from Trac 1.0 to 1.2 #to1.2 |
| 74 | |
| 75 | ===== Python 2.5 no longer supported |
| 76 | |
| 77 | Upgrade Python to at least 2.6 or 2.7, but not 3.0 or greater. |
| 78 | |
| 79 | ===== Obsolete Plugins |
| 80 | |
| 81 | Trac has added functionality equivalent to the following plugins: |
| 82 | * [https://trac-hacks.org/wiki/AdminEnumListPlugin AdminEnumListPlugin] |
| 83 | * [https://trac-hacks.org/wiki/DateFieldPlugin DateFieldPlugin]: see the **time** [TracTicketsCustomFields#AvailableFieldTypesandOptions custom field type] |
| 84 | * [https://trac-hacks.org/wiki/GroupBasedRedirectionPlugin GroupBasedRedirectionPlugin]: the default handler can set as a user preference. |
| 85 | * [https://trac-hacks.org/wiki/LinenoMacro LinenoMacro]: see WikiProcessors#AvailableProcessors |
| 86 | * [https://trac-hacks.org/wiki/NeverNotifyUpdaterPlugin NeverNotifyUpdaterPlugin]: see [TracNotification#notification-subscriber-section notification subscribers] |
| 87 | * [https://trac-hacks.org/wiki/QueryUiAssistPlugin QueryUiAssistPlugin]: see TracQuery#Filters. |
| 88 | * [https://trac-hacks.org/wiki/TicketCreationStatusPlugin TicketCreationStatusPlugin]: see [#NewWorkflowActions] |
| 89 | |
| 90 | The plugins should be removed when upgrading Trac to 1.2. |
| 91 | |
| 92 | ===== New workflow actions #NewWorkflowActions |
| 93 | |
| 94 | The ticket creation step is controlled with a [TracWorkflow#TicketCreateAction 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. |
| 95 | |
| 96 | ===== New permissions policy for read-only wiki pages |
| 97 | |
| 98 | 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: |
| 99 | {{{#!ini |
| 100 | [trac] |
| 101 | permission_policies = ReadonlyWikiPolicy, |
| 102 | DefaultPermissionPolicy, |
| 103 | LegacyAttachmentPolicy |
| 104 | }}} |
| 105 | |
| 106 | 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. |
| 107 | |
76 | 108 | ==== Upgrading from Trac 0.12 to Trac 1.0 #to1.0 |
77 | 109 | |
78 | 110 | ===== Python 2.4 no longer supported |
| 111 | |
79 | 112 | Upgrade Python to at least 2.5, but not 3.0. |

90 | 123 | |
91 | 124 | ===== Subversion components not enabled by default for new installations |
| 125 | |
92 | 126 | 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: |
93 | 127 | {{{#!ini |
… |
… |
|
95 | 129 | tracopt.versioncontrol.svn.* = enabled |
96 | 130 | }}} |
| 131 | |
97 | 132 | The upgrade procedure should take care of this and change the TracIni appropriately, unless you already had the svn components explicitly disabled. |
98 | 133 | |
99 | 134 | ===== Attachments migrated to new location |
| 135 | |
100 | 136 | 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. |
101 | 137 | |
102 | 138 | ===== Behavior of `[ticket] default_owner` changed |
| 139 | |
103 | 140 | 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. |
104 | 141 | |

… |
|
106 | 143 | |
107 | 144 | ===== Python 2.3 no longer supported |
| 145 | |
108 | 146 | The minimum supported version of Python is now 2.4. |
109 | 147 | |
110 | 148 | ===== SQLite v3.x required |
| 149 | |
111 | 150 | 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. |
112 | 151 | |
113 | 152 | ===== [trac:PySqlite] 2 required |
| 153 | |
114 | 154 | [trac:PySqlite] 1.1.x is no longer supported. Please install 2.5.5 or later if possible, see [#Tracdatabaseupgrade Trac database upgrade] below. |

131 | 171 | ===== Multiple Repository Support |
| 172 | |
132 | 173 | The latest version includes support for multiple repositories. If you plan to add more repositories to your Trac instance, please refer to TracRepositoryAdmin#Migration. |

143 | 184 | |
144 | 185 | ===== Improved repository synchronization |
| 186 | |
145 | 187 | In addition to supporting multiple repositories, there is now a more efficient method for synchronizing Trac and your repositories. |

|
150 | 192 | |
151 | 193 | ===== Authz permission checking |
| 194 | |
152 | 195 | 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. |
153 | 196 | |
154 | 197 | ===== Microsecond timestamps |
| 198 | |
155 | 199 | 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. |
156 | 200 | |
157 | 201 | ==== Upgrading from Trac 0.10 to Trac 0.11 |
| 202 | |
158 | 203 | ===== Site Templates and Styles |
| 204 | |
159 | 205 | The templating engine has changed in 0.11 to Genshi, please look at TracInterfaceCustomization for more information. |
160 | 206 | |

… |
|
162 | 208 | |
163 | 209 | ===== Trac Macros, Plugins |
| 210 | |
164 | 211 | 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. |
165 | 212 | |
166 | 213 | ===== For FCGI/WSGI/CGI users |
| 214 | |
167 | 215 | For those who run Trac under the CGI environment, run this command in order to obtain the trac.*gi file: |
168 | 216 | {{{#!sh |
… |
… |
|
173 | 221 | |
174 | 222 | ===== Web Admin plugin integrated |
| 223 | |
175 | 224 | If you had the [trac:WebAdmin] plugin installed, you can uninstall it as it is part of the Trac code base since 0.11. |
176 | 225 | |
177 | 226 | ===== New Default Configurable Workflow |
178 | 227 | |
179 | | 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. |
180 | | |
181 | | Graphically, that looks like this: |
| 228 | 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: |
182 | 229 | |
183 | 230 | {{{#!Workflow width=500 height=240 |
… |
… |
|
201 | 248 | 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. |
202 | 249 | |
203 | | ===== Global Configuration |
204 | | 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. |
