| BitBake 'Fetch' git implementation |
| |
| git fetcher support the SRC_URI with format of: |
| SRC_URI = "git://some.host/somepath;OptionA=xxx;OptionB=xxx;..." |
| |
| Supported SRC_URI options are: |
| |
| - branch |
| The git branch to retrieve from. The default is "master" |
| |
| This option also supports multiple branch fetching, with branches |
| separated by commas. In multiple branches case, the name option |
| must have the same number of names to match the branches, which is |
| used to specify the SRC_REV for the branch |
| e.g: |
| SRC_URI="git://some.host/somepath;branch=branchX,branchY;name=nameX,nameY" |
| SRCREV_nameX = "xxxxxxxxxxxxxxxxxxxx" |
| SRCREV_nameY = "YYYYYYYYYYYYYYYYYYYY" |
| |
| - tag |
| The git tag to retrieve. The default is "master" |
| |
| - protocol |
| The method to use to access the repository. Common options are "git", |
| "http", "https", "file", "ssh" and "rsync". The default is "git". |
| |
| - rebaseable |
| rebaseable indicates that the upstream git repo may rebase in the future, |
| and current revision may disappear from upstream repo. This option will |
| remind fetcher to preserve local cache carefully for future use. |
| The default value is "0", set rebaseable=1 for rebaseable git repo. |
| |
| - nocheckout |
| Don't checkout source code when unpacking. set this option for the recipe |
| who has its own routine to checkout code. |
| The default is "0", set nocheckout=1 if needed. |
| |
| - bareclone |
| Create a bare clone of the source code and don't checkout the source code |
| when unpacking. Set this option for the recipe who has its own routine to |
| checkout code and tracking branch requirements. |
| The default is "0", set bareclone=1 if needed. |
| |
| - nobranch |
| Don't check the SHA validation for branch. set this option for the recipe |
| referring to commit which is valid in tag instead of branch. |
| The default is "0", set nobranch=1 if needed. |
| |
| - usehead |
| For local git:// urls to use the current branch HEAD as the revision for use with |
| AUTOREV. Implies nobranch. |
