When enough reviewers have approved a code change, you can submit the change to the code base.<\/p>\n<p>In addition to the store of Pending Changes, Gerrit captures notes and comments made about each change. This enables you to review changes at your convenience or when a conversation about a change can\u2019t happen in person. In addition, notes and comments provide a history of each change (what was changed and why and who reviewed the change).<\/p>\n<p>Gerrit project is a workspace consisting of the following elements:<\/p>\n<ul>\n<li>Git repository: It is used to store the merged code base and the changes under review that have not being merged yet. Gerrit has the limitation of a single repository per project. There can also be projects without any code repository associated at all (that is, Security-only projects)<\/li>\n<li>Changes references under review: Git commit-id (expressed as SHA-1 Hexadecimal alphanumeric string) stored in the Gerrit DB and pointing to the corresponding changes stored in the Git repository. A Gerrit change is a Git commit object uploaded for review and associated to its comments and scores. It is stored in the project&#8217;s Git repository but it is not visible\/accessible from the normal Git graph of commits, even it does start from a point on the commits graph.<\/li>\n<li>Access Control Lists (ACLs): It contains the list of roles defined for the Gerrit project and the associated access permissions to the Git repository branches.<\/li>\n<li>Prolog rules: It is the set of rules that govern the Code Review process for the project. 0 Additional metadata: All the extra settings such as description, merge strategy, contributor agreements, and accessory metadata needed in order to manage the project.<\/li>\n<\/ul>\n<p><strong>We have to make and review a change through these stages in Gerrit:<\/strong><\/p>\n<ol>\n<li>Making the change.<\/li>\n<li>Creating the review.<\/li>\n<li>Reviewing the change.<\/li>\n<li>Reworking the change.<\/li>\n<li>Verifying the change.<\/li>\n<li>Submitting the change.<\/li>\n<\/ol>\n<p><a href=\"https:\/\/www.scmgalaxy.com\/tutorials\/wp-content\/uploads\/2018\/08\/gerrit-architecture.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-5152\" src=\"https:\/\/www.scmgalaxy.com\/tutorials\/wp-content\/uploads\/2018\/08\/gerrit-architecture.png\" alt=\"\" width=\"1145\" height=\"553\" srcset=\"https:\/\/www.scmgalaxy.com\/tutorials\/wp-content\/uploads\/2018\/08\/gerrit-architecture.png 1145w, https:\/\/www.scmgalaxy.com\/tutorials\/wp-content\/uploads\/2018\/08\/gerrit-architecture-300x145.png 300w, https:\/\/www.scmgalaxy.com\/tutorials\/wp-content\/uploads\/2018\/08\/gerrit-architecture-768x371.png 768w, https:\/\/www.scmgalaxy.com\/tutorials\/wp-content\/uploads\/2018\/08\/gerrit-architecture-1024x495.png 1024w, https:\/\/www.scmgalaxy.com\/tutorials\/wp-content\/uploads\/2018\/08\/gerrit-architecture-660x319.png 660w\" sizes=\"auto, (max-width: 1145px) 100vw, 1145px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When Gerrit is configured as the central source repository, all code changes are sent to Pending Changes for others to [&hellip;]<\/p>\n","protected":false},"author":4,"featured_media":5178,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_joinchat":[],"footnotes":""},"categories":[4994],"tags":[4922,945],"class_list":["post-5151","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-gerrit","tag-architecture","tag-gerrit"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>How Gerrit Works?
