The classloader hacking causes subtle downstream effects, breaking unrelated tests. the testCglibClassesAreLoadedJustInTimeForEnhancement() method as it turns out this was one of the culprits in the recent build breakage. For example, take a look at these gems from my early days committing to Spring: $ git log -oneline -5 -author cbeams -before "Fri Mar 26 2009"Į5f4b49 Re-adding ConfigurationPostProcessorTests after its brief removal in r814. If you browse the log of any random Git repository, you will probably find its commit messages are more or less a mess. So go ahead and switch over to that new coding standard git won't hold you back anymore.Contents: Introduction | The Seven Rules | Tips Introduction: Why good commit messages matter You can even share a list of ignored commits with your entire team. Fear of polluting the git blame output no longer has to be a blocker for applying style changes in bulk: these commits can now be ignored. Git 2.23 contains an absolute game changer that is not even mentioned in the release highlights. That way you can hit the ground running when it's time to upgrade. git-blame-ignore-revs file with commits you would like to hide from git blame. But even if you cannot upgrade yet for some reason, you can already start building a. On the git downloads page you can find out how to obtain the latest git for your platform. One last thing: be aware that you need at least version 2.23 of git to use these new features. It would be awesome if they added such a feature soon. Hope that this is considered a bug and will be fixed in an upcoming version.Īnother limitation to be aware of is that platforms like GitHub and GitLab do not yet support files with commits to ignore for the 'blame'-button in their user interface. Be aware however that git currently gives an error when this setting is configured globally but a repository has no. git-blame-ignore-revs naming convention you can even set this configuration variable globally, so that it applies to all your repositories, each with their own. This causes git to automatically ignore the commits specified in that file for every call to git blame. This means that even after our bulk style change, we can get back a meaningful context for the 'real' changes to our function: Lines changed by the ignored commit will be attributed to the previous commit touching that line instead. Using -ignore-rev, one can specify a commit to be ignored by git blame. To limit the impact of such 'unimportant' bulk commits, git 2.23 adds a new option to git blame. That means they have to live with either a coding standard that they would rather not have, or with a codebase that does not follow their standards. ' bottles of cider on the wall.' īecause these bulk changes render git blame useless, many teams refrain from applying automated style changes of this magnitude. +function describeBottles (int $amount = 42 ): string +++ -1,5 +1,5 describeBottles (int $amount = 42 ): string If we would now use git blame to find the background for a line of code, the output would be:Ĭommit df0ee6b006ee0f90cccc18b71ced290f6cae18d9 (HEAD -> master )ĭiff -git a/describeBottles.php b/describeBottles.php It touches every line without altering the meaning or intent of the code. Now the team has one huge commit with style changes in their repository. There are similar tools for almost all other programming languages. Luckily there are tools like PHP-CS-Fixer and phpcbf to automatically convert the whole codebase to the new standard. One day they decide to adopt the PSR-2 coding style guide that has become popular in the PHP community. The team behind the describeBottles-function has always used their own coding standards, with opening braces on the same line and 'CRLF' line endings. This makes git blame an absolute life saver in legacy projects. Perhaps it contains the full user testing results, providing us with even more context. We even have a link to a Jira ticket where we can find more information.
