=================
buildstream 1.3.1
=================
o BREAKING CHANGE: Default strip-commands have been removed as they are too
specific. Recommendation if you are building in Linux is to use the
ones being used in freedesktop-sdk project, for example
o All elements must now be suffixed with `.bst`
Attempting to use an element that does not have the `.bst` extension,
will result in a warning.
o BREAKING CHANGE: The 'manual' element lost its default 'MAKEFLAGS' and 'V'
environment variables. There is already a 'make' element with the same
variables. Note that this is a breaking change, it will require users to
make changes to their .bst files if they are expecting these environment
variables to be set.
o Failed builds are included in the cache as well.
`bst checkout` will provide anything in `%{install-root}`.
A build including cached fails will cause any dependant elements
to not be scheduled and fail during artifact assembly,
and display the retry prompt during an interactive session.
o Due to enabling the use of relative workspaces, "Legacy" workspaces
may need to be closed and remade before the changes will affect them.
Downgrading after using this feature may result in workspaces
not functioning correctly
o Elements may now specify 'build-depends' and 'runtime-depends' fields
to avoid having to specify the dependency type for every entry in
'depends'.
o Source plugins may now request access access to previous during track and
fetch by setting `BST_REQUIRES_PREVIOUS_SOURCES_TRACK` and/or
`BST_REQUIRES_PREVIOUS_SOURCES_FETCH` attributes.
o Add new `pip` source plugin for downloading python packages using pip,
based on requirements files from previous sources.
o Generate Docker images from built artifacts using
`contrib/bst-docker-import` script.
o Added Documentation on how to create out of source builds. This includes the
new the `conf-root` variable to make the process easier. And there has been
a bug fix to workspaces so they can be build in workspaces too.
o Creating a build shell through the interactive mode or `bst shell --build`
will now use the cached build tree if available locally. It is now easier to
debug local build failures.
o `bst shell --sysroot` now takes any directory that contains a sysroot,
instead of just a specially-formatted build-root with a `root` and `scratch`
subdirectory.
o The buildstream.conf file learned new 'prompt.auto-init',
'prompt.really-workspace-close-remove-dir', and
'prompt.really-workspace-reset-hard' options. These allow users to suppress
certain confirmation prompts, e.g. double-checking that the user meant to
run the command as typed.
o Due to the element `build tree` being cached in the respective artifact their
size in some cases has significantly increased. In *most* cases the build trees
are not utilised when building targets, as such by default bst 'pull' & 'build'
will not fetch build trees from remotes. This behaviour can be overridden with
the cli main option '--pull-buildtrees', or the user configuration cache group
option 'pull-buildtrees = True'. The override will also add the build tree to
already cached artifacts. When attempting to populate an artifactcache server
with cached artifacts, only 'complete' elements can be pushed. If the element
is expected to have a populated build tree then it must be cached before pushing.
o Added new `bst source-checkout` command to checkout sources of an element.
o `bst workspace open` now supports the creation of multiple elements and
allows the user to set a default location for their creation. This has meant
that the new CLI is no longer backwards compatible with buildstream 1.2.
o Add sandbox API for command batching and use it for build, script, and
compose elements.
o BREAKING CHANGE: The `git` plugin does not create a local `.git`
repository by default. If `git describe` is required to work, the
plugin has now a tag tracking feature instead. This can be enabled
by setting 'track-tags'.
=================
buildstream 1.1.5
=================
o Add a `--tar` option to `bst checkout` which allows a tarball to be
created from the artifact contents.
o Fetching and tracking will consult mirrors defined in project config,
and the preferred mirror to fetch from can be defined in the command
line or user config.
o Added new `remote` source plugin for downloading file blobs
o Add support for the new include '(@)' directive in project.conf and .bst files
=================
buildstream 1.1.4
=================
o `bst workspace` commands and `bst track` will substitute their
source elements when performing those operations, e.g. performing
`bst track` on a filter element will track the sources on the
element that it depends on (if it has sources).
o Added new simple `make` element
o Switch to Remote Execution CAS-based artifact cache on all platforms.
Artifact servers need to be migrated.
o BuildStream now requires python version >= 3.5
o BuildStream will now automatically clean up old artifacts when it
runs out of space. The exact behavior is configurable in the user's
buildstream.conf.
=================
buildstream 1.1.3
=================
o Added new `bst init` command to initialize a new project.
o Cross junction tracking is now disabled by default for projects
which can support this by using project.refs ref-storage
New options have been added to explicitly enable cross-junction
tracking.
o Failed jobs are now summarised at the end of a build.
Use `--verbose` and `--no-verbose` to adjust the amount of detail given.
o BuildElements' `configure-commands` are only run once for
workspaces now, which allows for incremental builds.
Appropriate API for plugins is also exposed through
`Element.prepare`.
o The `cmake` plugin now supports building with ninja with the
newly added `generator` configuration option.
o `bst workspace close` and `bst workspace reset` now support multiple
elements. All elements can be specified using `--all`.
o The elements whose cache keys had to be determined during the build
are summarised at the end of the build.
o Fixed versioning introspection to be dynamic, many users use
a developer install mode so they can update with git, now the
version information is always up to date in logs.
This causes a minor API break: The --version output now only
outputs the version.
=================
buildstream 1.1.2
=================
o New ref-storage option allows one to store source refs, such
as git shas, in one central project.refs file instead of inline
with the source declarations.
o Deprecated `--track-save` optionality in `bst build`, this
does not make sense to support now that we have project.refs.
o Added the `sandbox` configuration option which can be used in
`project.conf` and elements, to control the user ID and group ID
used in build sandboxes.
o Added new `deb` source implementation, for staging of downloaded
deb package files.
=================
buildstream 1.1.1
=================
o New project configuration controlling how the sandbox behaves
when `bst shell` is used; allowing projects to provide a more
functional shell environment.
o The `bst shell` command now has a `--mount` option allowing
users to mount files and directories into the sandbox for
testing purposes.
o Log lines are now configurable with the new "message-format"
user configuration, allowing one to express optional fields
such as microsecond precision and wallclock time.
o Newly added filter element
o Git source plugin now allows disabling of submodule checkouts
o In the same way we allow overriding element configurations
by their 'kind' in project.conf, we now support the same
for source plugin configurations.
o Tar and zip sources now automatically recall an `etag`
from the http headers, optimizing tracking of tarballs
significantly (issue #62)
=================
buildstream 1.1.0
=================
o Multiple artifact caches are now supported in project and
user configuration with a priority order (issue #85)
o Add junction support for subprojects
o Changes towards incremental builds in workspaces
o `bst shell --build` now creates true build sandbox
o Many bug fixes
=================
buildstream 1.0.0
=================
First stable release of BuildStream
BuildStream 1.0.0 is all about API stability - for the past months we
have been reviewing our various API surfaces, implementing strategies
for revisioning of our interfaces and cleaning up. Long term stability
is very important for build reproducibility over time, and this release
is the first promise we are making on any API surfaces.
Stable API surfaces include:
o The command line interface
o The YAML user configuration file format
o The YAML project `.bst` file format
o The core Python module imported by external plugins
