TracUpgrade
v1 v2 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 the easiest to use it also to upgrade you Trac installation. 13 13 14 14 {{{ 15 # easy_install --upgrade Trac 15 # easy_install --upgrade Trac=0.12beta1 16 16 }}} 17 (once beta1 is released, that is) 17 18 18 19 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]). … … 20 21 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 22 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-packages23 * on Linux: `/usr/lib/python2.X/site-packages` 24 * on Windows: `C:\Python2.X\lib\site-packages` 25 * on MacOSX: `/Library/Python/2.X/site-packages` 25 26 26 27 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). 27 28 28 29 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.31 30 32 31 === 2. Upgrade the Trac Environment === #UpgradetheTracEnvironment … … 46 45 trac-admin /path/to/projenv upgrade --no-backup 47 46 }}} 48 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 47 51 48 === 3. Update the Trac Documentation === #UpdatetheTracDocumentation … … 67 64 68 65 === 5. Steps specific to a given Trac version === 69 ==== Upgrading to Trac 0.12 ==== 66 ==== Upgrading from Trac 0.11 to Trac 0.12 ==== 67 ===== Python 2.3 no longer supported ===== 68 The minimum supported version of python is now 2.4 69 70 ===== SQLite v3.x required ===== 70 71 SQLite v2.x is no longer supported, if you happen to still use a Trac database using this format, you'll need to convert it to SQLite v3.x first. See [trac:PySqlite#UpgradingSQLitefrom2.xto3.x] for details. 71 72 72 ==== Upgrading to Trac 0.11 ==== 73 ===== Site Templates ===== 74 The templating engine has changed in 0.11, please look at TracInterfaceCustomization for more information. 73 ===== Multiple Repository Support ===== 74 If you plan to add more repositories to your Trac instance, as this is now possible with the newly introduced multiple repository support, please refer to TracRepositoryAdmin#Migration. 75 76 This can be of interest even if you only have one repository, as there's now a way to avoid the potentially costly resync check at every request. 77 78 ===== Improved repository synchronization ===== 79 In addition to supporting multiple repositories, a new more efficient method for synchronizing Trac and your repositories was implemented. 80 81 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. 82 83 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. 84 85 ==== Upgrading from Trac 0.10 to Trac 0.11 ==== 86 ===== Site Templates and Styles ===== 87 The templating engine has changed in 0.11 to Genshi, please look at TracInterfaceCustomization for more information. 88 89 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. 75 90 76 91 ===== Trac Macros, Plugins ===== … … 85 100 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. 86 101 102 ===== Web Admin plugin integrated ===== 103 If you had the webadmin plugin installed, you can uninstall it as it is part of the Trac code base since 0.11. 104 87 105 === 6. Restart the Web Server === #RestarttheWebServer 88 106 … … 93 111 === parent dir === 94 112 If you use a trac parent env configuration and one of the plugins in one child does not work, none of the children work. 95 96 === some core modules won't load ===97 This can happen in particular with Python 2.3 on Windows when upgrading without uninstalling first.98 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:99 {{{100 ERROR: Skipping "trac.about = trac.about": (can't import "No module named about")101 }}}102 Remove the `Lib/site-packages/trac` folder and reinstall.103 113 104 114 === Wiki Upgrade === … … 113 123 == Older Versions == 114 124 115 For upgrades from versions older than Trac 0.10, refer first to trac:wiki:0.10/TracUpgrade. 116 117 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. 118 {{{ 119 $ sqlite3 db/trac.db "update system set value=20 where name='database_version'" 120 }}} 121 (upgrade can be redone the normal way later on) 125 For upgrades from versions older than Trac 0.10, refer first to [trac:wiki:0.10/TracUpgrade#SpecificVersions]. 122 126 123 127 -----
