![]() URLs by looking for source files in a specific search order: When the download() method is called, BitBake tries to resolve the (sstate) code uses the fetch module to fetch the sstate files. In OpenEmbedded for example, the shared state The SRC_URI and WORKDIR variables are not hardcoded into theįetcher, since those fetcher methods can be (and are) called withĭifferent variable names. If you want to see the above code in action,Įxamine the OpenEmbedded class file base.bbclass The code to execute the first part of this process, a fetch, looksįor convenience, the naming in these examples matches the variables Patching, however, is not covered by this module. GettingĪnd unpacking the files is often optionally followed by patching. The files from somewhere (cached or otherwise) and then unpacking thoseįiles into a specific location and perhaps in a specific way. Theįetcher codebase deals with two distinct processes in order: obtaining 4.1 The Download (Fetch) īitBake takes several steps when fetching source code or files. “fetch” refers to “fetch2” in this manual. Obsolete and has been removed from the codebase. It is the second major version of the API. The current fetch module is called “fetch2” and refers to the fact that As such, this module forms an important part of BitBake. Fetching source code is one of the cornerstones of building With the intricacies of downloading source code and files from remote Previous HEAD position was 132abfe.BitBake’s fetch module is a standalone piece of library code that deals Now the tool has been switched to the version v1.0. Nothing to commit, working directory clean If you want to create a new branch to retain commits you create, you mayĭo so (now or later) by using -b with the checkout command again. State without impacting any branches by performing another checkout. You can look around, make experimentalĬhanges and commit them, and you can discard any commits you make in this Now, let’s check out the first version of the tool. To see the current version of the tool, use “git describe”. +++ -1,3 +1,6 is a test file for git tag. Let’s do some modification for the tool and then create another tag for it. +++ -0,0 +1,3 is a test file for git tag.īy doing the above procedure, a tag has been added to the tool. ![]() $git tag -a v1.0 -m "the first tag" $git tagĬommit 132abfe4e4ce8f8cefaf2ad9bb1f39c59d5f2b7b !!!NOTE: Commit first before adding the tag to the tool. The following example shows how to add a tag to the tool, and how to switch between different versions of the tool. You can delete a tag any time if that version is discarded by using the command “git tag –d v1.0”. You can check out a specific version of the tool by using the command “git checkout v1.0”. You can see the tag data along with the commit that was tagged by using the git show command. If you don’t specify a message for an annotated tag, Git launches your editor so you can type it in. The -m specifies a tagging message, which is stored with the tag. The easiest way is to specify -a when you run the tag command: $ git tag -a v1.0 -m 'first release' They’re checksummed contain the tagger name, e-mail, and date have a tagging message and can be signed and verified with GNU Privacy Guard (GPG).Ĭreating an annotated tag in Git is simple. However, it is highly recommended to use the annotated tags, because they are stored as full objects in the Git database. Git uses two main types of tags: lightweight and annotated. Generally, people use this functionality to mark release points (v1.0, and so on). Like most VCSs, Git has the ability to tag specific points in history as being important.
