TracUpgrade
v1 v2 4 4 == Instructions == 5 5 6 Typically, there are fivesteps involved in upgrading to a newer version of Trac:6 Typically, there are seven steps involved in upgrading to a newer version of Trac: 7 7 8 8 === 1. Update the Trac Code === #UpdatetheTracCode … … 10 10 Get the new version as described in TracInstall, or your operating system specific procedure. 11 11 12 If you installed a recent 0.11 version of Trac via {{{easy_install}}}, it might be the easiest to use it also to upgrade you Trac installation.12 If you already have a 0.11 version of Trac installed via `easy_install`, it might be easiest to also use `easy_install` to upgrade your Trac installation: 13 13 14 14 {{{ 15 # easy_install --upgrade Trac 15 # easy_install --upgrade Trac==0.12 16 16 }}} 17 17 18 If you do a manual (not operating system specific) upgrade, you should also stop any running Trac server before the installation. Doing "hot" upgrades is not advised, especially not on Windows ([trac:ticket:7625#7265]).18 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]). 19 19 20 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 .eggs from former versions.21 The location of the site-packages directory depends on the operating system , and the location in which Python was installed. However, the following locations are common:22 * on Linux: /usr/lib/python2.X/site-packages23 * on Windows: C:\Python2.X\lib\site-packages24 * on MacOSX: /Library/Python/2.X/site-packages20 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. 21 The location of the site-packages directory depends on the operating system and the location in which Python was installed.

(The exact location depends on your platform.) 27 27 28 This cleanup is not mandatory, but it makes it easier to troubleshoot issues later on, as you won't waste your time looking at code or templates from a previous release that are not being used anymore... As usual, make a backup before actually deleting things. 29 30 If you had the webadmin plugin installed, you can now uninstall it as it is now part of the Trac code base. 28 This cleanup is not mandatory, but makes it easier to troubleshoot issues later on, as you won't waste your time looking at code or templates from a previous release that are not being used anymore...

Upgrade the Trac Environment === #UpgradetheTracEnvironment … … 47 45 }}} 48 46 49 If you are using custom CSS styles or modified templates in the templates directory of the TracEnvironment, you will need to convert them to the Genshi way of doing things. To continue to use your style sheet, follow the instructions at TracInterfaceCustomization#SiteAppearance.50 51 47 === 3.

Resynchronize the Trac Environment Against the Source Code Repository === … … 63 59 64 60 {{{ 65 trac-admin /path/to/projenv re sync61 trac-admin /path/to/projenv repository resync '*' 66 62 }}} 67 63 68 === 5. Steps specific to a given Trac version === 69 ==== Upgrading to Trac 0.11 ==== 70 ===== Site Templates ===== 71 The templating engine has changed in 0.11, please look at TracInterfaceCustomization for more information. 64 === 5. Refresh static resources === 65 66 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: 67 {{{ 68 trac-admin /path/to/env deploy /deploy/path 69 }}} 70 this will extract static resources and CGI scripts (`trac.wsgi`, etc) from new Trac version and its plugins into `/deploy/path`. 71 72 Some web browsers cache CSS and Javascript files persistently, so you may need to instruct your users to manually erase the contents of their browser's cache. 73 74 === 6. Steps specific to a given Trac version === 75 ==== Upgrading from Trac 0.11 to Trac 0.12 ==== 76 ===== Python 2.3 no longer supported ===== 77 The minimum supported version of python is now 2.4 78 79 ===== SQLite v3.x required ===== 80 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. 81 82 ===== PySqlite 2 required ===== 83 PySqlite 1.1.x is no longer supported. Please install 2.5.5 or later if possible (see [#Tracdatabaseupgrade Trac database upgrade] below). 84 85 ===== Multiple Repository Support ===== 86 The latest version includes support for multiple repositories. If you plan to add more repositories to your Trac instance, please refer to TracRepositoryAdmin#Migration. 87 88 This may be of interest to users with only one repository, since there's now a way to avoid the potentially costly resync check at every request. 89 90 ===== Improved repository synchronization ===== 91 In addition to supporting multiple repositories, there is now a more efficient method for synchronizing Trac and your repositories. 92 93 While you can keep the same synchronization as in 0.11 adding the post-commit hook as outlined in TracRepositoryAdmin#Synchronization and TracRepositoryAdmin#ExplicitSync will allow more efficient synchronization and is more or less required for multiple repositories. 94 95 Note that if you were using the `trac-post-commit-hook`, ''you're strongly advised to upgrade it'' to the new hook documented in the above references, as the old hook will not work with anything else than the default repository and even for this case, it won't trigger the appropriate notifications. 96 97 ===== Authz permission checking ===== 98 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). 99 100 ==== Upgrading from Trac 0.10 to Trac 0.11 ==== 101 ===== Site Templates and Styles ===== 102 The templating engine has changed in 0.11 to Genshi, please look at TracInterfaceCustomization for more information. 103 104 If you are using custom CSS styles or modified templates in the `templates` directory of the TracEnvironment, you will need to convert them to the Genshi way of doing things. To continue to use your style sheet, follow the instructions at TracInterfaceCustomization#SiteAppearance. 72 105 73 106 ===== Trac Macros, Plugins ===== 74 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 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.107 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. 75 108 76 109 ===== For FCGI/WSGI/CGI users ===== … … 82 115 This will create a deploy directory with the following two subdirectories: `cgi-bin` and `htdocs`. Then update your Apache configuration file `httpd.conf` with this new `trac.cgi` location and `htdocs` location. 83 116 84 === 6. Restart the Web Server === #RestarttheWebServer 117 ===== Web Admin plugin integrated ===== 118 If you had the webadmin plugin installed, you can uninstall it as it is part of the Trac code base since 0.11. 119 120 === 7. Restart the Web Server === #RestarttheWebServer 85 121 86 122 If you are not running [wiki:TracCgi CGI], reload the new Trac code by restarting your web server. … … 91 127 If you use a trac parent env configuration and one of the plugins in one child does not work, none of the children work. 92 128 93 === some core modules won't load ===94 This can happen in particular with Python 2.3 on Windows when upgrading without uninstalling first.95 Some modules were previously capitalized and were changed to lower case, e.g. trac/About.py became trac/about.py. You may find such messages in the Trac log:96 {{{97 ERROR: Skipping "trac.about = trac.about": (can't import "No module named about")98 }}}99 Remove the `Lib/site-packages/trac` folder and reinstall.100 101 129 === Wiki Upgrade === 102 130 `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. 103 131 132 === Trac database upgrade === 133 134 A known issue in some versions of PySqlite (2.5.2-2.5.4) prevents the trac-admin upgrade script from successfully upgrading the database format. It is advised to use either a newer or older version of the sqlite python bindings to avoid this error. For more details see ticket [trac:#9434]. 135 136 == Upgrading Python == 137 138 Upgrading Python to a newer version will require reinstallation of Python packages: Trac of course; also [http://pypi.python.org/pypi/setuptools easy_install], if you've been using that. Assuming you're using Subversion, you'll also need to upgrade the Python bindings for svn. 139 140 === Windows and Python 2.6 === 141 142 If you've been using !CollabNet's Subversion package, you may need to uninstall that in favor of [http://alagazam.net/ Algazam], which has the Python bindings readily available (see TracSubversion). The good news is, that works with no tweaking. 104 143 105 144 == Changing Database Backend == … … 110 149 == Older Versions == 111 150 112 For upgrades from versions older than Trac 0.10, refer first to trac:wiki:0.10/TracUpgrade. 113 114 Note that downgrading from Trac 0.11 to Trac 0.10.4 or 0.10.5 is easy, but has to be done manually, e.g. 115 {{{ 116 $ sqlite3 db/trac.db "update system set value=20 where name='database_version'" 117 }}} 118 (upgrade can be redone the normal way later on) 151 For upgrades from versions older than Trac 0.10, refer first to [trac:wiki:0.10/TracUpgrade#SpecificVersions]. 119 152 120 153 -----
