The SRC_URI and WORKDIR variables are not hardcoded into theįetcher, since those fetcher methods can be (and are) called withĭifferent variable names.

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 Additionally, the tool comes with all modern conveniences: The assistant uses the Linux kernel's inotify interface to detect changed files, for example, and to trigger a sync (Figure 1).BitBake’s fetch module is a standalone piece of library code that deals This GUI uses a local web server to provide users with a modern web interface in the browser.

To make what sounds like a very technical piece of software more accessible to the general public, Hess wrote the git-annex assistant. If desired, however, users can follow GnuPG customs and encrypt with a specific public key. GnuPG handles encryption, automatically using a locally generated key by default.

For bona fide archivists, the Amazon Glacier offline store and the public are also supported. In addition to these basic operations, which are described step by step on the git-annex website, numerous variations and accessories are available: The repositories supported by the tool, besides local directories and removable media, include remote servers (assuming they offer SSH access), ownCloud, the Google Drive online service, Amazon S3, Box.com, and. They create the repository on the stick and link the two repositories: Each sees the other side as a remote repository, with which it then synchronizes.

If you want to add another repository to your file storage, such as a USB stick, the commands in Listing 1 will help. Then, all data is stored below the hidden. By default, repositories are in indirect mode. This is the only mode in which you have access to the files. The following commands convert the ~/annex directory into a git-annex repository named My PC: cd ~/annexīefore you can store files in this directory, you need to put it in direct mode by issuing the git annex direct command. Git-annex comes with command-line tools that are quickly and easily learned for technically inclined users, especially if they know Git. A proprietary storage back end stores the files in the. The developer's trick: Git-annex only checks in the metadata, along with a symbolic link, in Git. However, the version control system was designed for storing many small source files, not for large video files, which cause performance and space problems. In both scenarios, the users benefit from the fact that Git repositories can store and compare data in a decentralized way. All she needs is a WiFi connection in a café she automatically encrypts the files she stores with the cloud provider. Git-annex helps Alice find the correct files while she's on the road. In comparison, Alice is permanently on the road with her netbook and USB hard drive and has rented a web server and cloud storage. For safety reasons, git-annex can also create multiple copies of each file. The archivist can use git-annex to manage myriad files in a single directory tree, even though the files are spread across multiple servers and even across removable hard drives.

On the git-annex homepage, Hess describes two target groups for the software: Bob the archivist and Alice the globetrotter.
