This page contains a couple of guidelines and rules that we want to try to follow when it comes to managing the manifests.
Since most of our projects can be found on GitHub, we are using that as the main remote. If you need to include other remotes for some reason, then that is OK, but please double check of there is any maintained (and preferably official) mirror for the project at GitHub before adding a new remote.
To have some kind of structure of the files, we have split them up in three
sections, one for pure OP-TEE gits, one for OP-TEE supporting gits found at
linaro-swg and then a third,
misc section where everything else can be
found. I.e., a template looks like this (this also includes the default remote
<?xml version="1.0" encoding="UTF-8"?> <manifest> <remote name="github" fetch="https://github.com" /> <default remote="github" revision="master" /> <!-- OP-TEE gits --> <!-- linaro-swg gits --> <!-- Misc gits --> </manifest>
Project XML elements¶
<projects ... > lines should be on the format as shown below with the
attributes in this order. The reason for this is to have it uniformly done
across all manifests and that it will make it easier when comparing various
versions of manifests with diff tools. All three attributes are mandatory.
The only exception is
revision which does not have to be stated if it is
master that we are tracking.
<project path="name_and_path_on_disk" name="upstream_name.git" revision="git_revsion" />
Within each of the three sections, all
<project ... > lines shall be
sorted in alphabetic order (this is again for making it easier to diff
manifests). The only expection here is
build.git which uses the
element. Having that at the end makes it look cleaner.
Additional XML attributes¶
If you are using another remote than the default, then that should come
revision attribute (this is true for all attributes other than
Alignment of XML attributes¶
The three mandatory XML attributes
revision should be
column aligned. Alignment of additional XML attributes are optional.
When to use clone-depth=”1”?¶
clone-depth="1" you are telling
git that you only want
a certain commit and not the entire git log history. You can only use this under
two conditions and that is when
revision is either a branch or a tag. Pure
SHA-1's does not work and will even raise
git sync errors
in some cases. So, the rules are, if you use either
revision="refs/heads/my_branch", then you
clone-depth="1" right after the
Spaces or tabs?¶
Only use spaces!
Here is an example showing the basis for an OP-TEE manifest. The names are fictive etc, but it describes everything said above.
<?xml version="1.0" encoding="UTF-8"?> <manifest> <remote name="github" fetch="https://github.com" /> <remote name="other" fetch="https://someotherlocation.com" /> <default remote="github" revision="master" /> <!-- OP-TEE gits --> <project path="optee_abc" name="OP-TEE/optee_abc.git" /> <project path="optee_def" name="OP-TEE/optee_def.git" /> <!-- linaro-swg gits --> <project path="lswg_abc" name="linaro-swg/lswg-abc.git" revision="aaaabbbbcccc93e64c2fdd6ae8b0be14a8c45719" /> <project path="lswg_def" name="linaro-swg/lswg-def.git" revision="ddddeeeeffff83e64c2fdd6ae8b0be14a8c45719" /> <!-- Misc gits --> <project path="my_other" name="my_other.git" revision="refs/tags/2017.11" clone-depth="1" remote="other" /> </manifest>
