bitbake: tests/fetch: handle network failures gracefully

2017-09-11T16:19:37+00:00

If there is a network failure the return value from latest_versionstring() is ('','') which later causes an exception when comparing versions. Improve this by checking the return value and failing the test early.

bitbake: tests/fetch: fix GitShallowTest.test_bitbake

2017-07-30T07:43:36+00:00

`git fetch --tags` seems to interact badly with `mirror=fetch`, resulting in the regular branches not being fetched, so drop the unnecessary `--tags`. This fixes this unit test failure: `bb.fetch2.FetchError: Fetcher failure: Unable to resolve 'master' in upstream git repository in git ls-remote output for /tmp/tmp4ag_mgmn/gitsource` [YOCTO #11698] (Bitbake rev: 2d0203fae08c5ff8dc3e9afaa9a819abc4a1af6f) Signed-off-by: Christopher Larson Signed-off-by: Richard Purdie

bitbake: fetch/git: add support for removing arbitrary revs for shallow

2017-06-02T12:36:57+00:00

In certain cases, it's valuable to be able to exert more control over what history is removed, beyond srcrev+depth. As one example, you can remove most of the upstream kernel history from a kernel repository, keeping predominently the non-publically-accessible content. If the repository is private, the history in that repo couldn't be restored via `git fetch --unshallow`, but upstream history could be. Example usage: # Remove only these revs, not at a particular depth BB_GIT_SHALLOW_DEPTH_pn-linux-foo = "0" BB_GIT_SHALLOW_REVS_pn-linux-foo = "v4.1" (Bitbake rev: 97f856f0455d014ea34c28b1c25f09e13cdc851b) Signed-off-by: Christopher Larson Signed-off-by: Richard Purdie

bitbake: fetch/gitannex: add support for shallow mirror tarballs

2017-06-02T12:36:57+00:00

When we're building from a shallow mirror tarball, we don't want to do anything with ud.clonedir, as it's not being used when we unpack. As such, disable updating annex in that case. Also include annex files in the shallow tarball. (Bitbake rev: ca0dd3c95502b22c369fbf37f915f45e02c06887) Signed-off-by: Christopher Larson Signed-off-by: Richard Purdie

bitbake: fetch/gitsm: add support for shallow mirror tarballs

2017-06-02T12:36:57+00:00

When we're building from a shallow mirror tarball, we don't want to do anything with ud.clonedir, as it's not being used when we unpack. As such, disable updating the submodules in that case. Also include the repositories in .git/modules in the shallow tarball. It does not actually make the submodule repositories shallow at this time.

bitbake: fetch/git: add support for keeping extra refs for shallow

2017-06-02T12:36:57+00:00

By default, all unused refs (branches & tags) are removed from the repository, as shallow processing scales with the number of refs it has to process. Add the ability to explicitly specify additional refs to keep. This is particularly useful for recipes with custom checkout processes, or whose git-based versioning requires a tag be available (i.e. for `git describe --tags`). The new `BB_GIT_SHALLOW_EXTRA_REFS` variable is a space-separated list of refs, fully specified, and support wildcards. Example usages: BB_GIT_SHALLOW_EXTRA_REFS = "refs/tags/v1.0" BB_GIT_SHALLOW_EXTRA_REFS += "refs/heads/*" (Bitbake rev: 1771934cd9f8b5847c6fcae0a906fb99d6b0db16) Signed-off-by: Christopher Larson Signed-off-by: Richard Purdie

bitbake: fetch/git: support per-branch/per-url depths for shallow

2017-06-02T12:36:57+00:00

Allow the user to explicitly adjust the depth for named urls/branches. The un-suffixed BB_GIT_SHALLOW_DEPTH is used as the default. Example usage: BB_GIT_SHALLOW_DEPTH = "1" BB_GIT_SHALLOW_DEPTH_doc = "0" BB_GIT_SHALLOW_DEPTH_meta = "0" (Bitbake rev: 9dfc517e5bcc6dd203a0ad685cc884676d2984c4) Signed-off-by: Christopher Larson Signed-off-by: Richard Purdie

bitbake: fetch/git: add support for shallow mirror tarballs

2017-06-02T12:36:57+00:00

This adds support to the git fetcher for fetching, using, and generating mirror tarballs of shallow git repositories. The external git-make-shallow script is used for shallow mirror tarball creation. This implements support for shallow mirror tarballs, not shallow clones. Supporting shallow clones directly is not really doable for us, as we'd need to hardcode the depth between branch HEAD and the SRCREV, and that depth would change as the branch is updated. When BB_GIT_SHALLOW is enabled, we will always attempt to fetch a shallow mirror tarball. If the shallow mirror tarball cannot be fetched, it will try to fetch the full mirror tarball and use that. If a shallow tarball is to be used, it will be unpacked directly at `do_unpack` time, rather than extracting it to DL_DIR at `do_fetch` time and cloning from there, to keep things simple. There's no value in keeping a shallow repository in DL_DIR, and dealing with the state for when to convert the clonedir to/from shallow is not worthwhile. To clarify when shallow is used vs a real repository, a current clone is preferred to either tarball, a shallow tarball is preferred to an out of date clone, and a missing clone will use either tarball (attempting the shallow one first). All referenced branches are truncated to SRCREV (that is, commits *after* SRCREV but before HEAD are removed) to further shrink the repository. By default, the shallow construction process removes all unused refs (branches/tags) from the repository, other than those referenced by the URL. Example usage: BB_GIT_SHALLOW ?= "1" # Keep only the top commit BB_GIT_SHALLOW_DEPTH ?= "1" # This defaults to enabled if both BB_GIT_SHALLOW and # BB_GENERATE_MIRROR_TARBALLS are enabled BB_GENERATE_SHALLOW_TARBALLS ?= "1" (Bitbake rev: 5ed7d85fda7c671be10ec24d7981b87a7d0d3366) Signed-off-by: Christopher Larson Signed-off-by: Richard Purdie

bitbake: git-make-shallow: add script to make a git repo shallow

2017-06-02T12:36:57+00:00

This script will be used by the git fetcher to create shallow mirror tarballs. usage: git-make-shallow [-h] [--ref REF] [--shrink] REVISION [REVISION ...] Remove the history of the specified revisions, then optionally filter the available refs to those specified. positional arguments: REVISION a git revision/commit optional arguments: -h, --help show this help message and exit --ref REF, -r REF remove all but the specified refs (cumulative) --shrink, -s shrink the git repository by repacking and pruning While git does provide the ability to clone at a specific depth, and fetch all remote refs at a particular depth, the depth is across all branches/tags, and doesn't provide the flexibility we need, hence this script. Refs (branches+tags) can be filtered, as the process of history removal scales up rapidly with the number of refs. Even the existing `git fetch --depth=` is extremely slow on an upstream kernel repository with all the branches and tags kept. This uses the same underlying mechanism to implement the history removal which git itself uses (.git/shallow), and the results, when configured similarly, are in line with the results git itself produces with `fetch --depth`.

bitbake: fetch2: handle absolute paths in subdir

2016-09-22T10:18:11+00:00

Currently if you use the subdir parameter in a SRC_URI and pass an absolute path then it gets appended to the unpack directory instead of being used directly. This is inconvenient as it may be useful to use ${S} when you want to unpack a file into the source tree. Change this behaviour so that absolute paths are used directly instead of being appended to the root directory. To ensure that recipes cannot write files to an arbitrary location enforce that the subdir starts with the unpack root.
