bitbake: parse: Make include_all raise a parse error for absolute paths

2025-11-07T13:15:35+00:00

It makes no sense to use an absolute path with include_all. (Bitbake rev: 2b19f7b1678974050192a1962244bba594c07bc1) Signed-off-by: Peter Kjellerstedt Signed-off-by: Mathieu Dubois-Briand Signed-off-by: Richard Purdie

bitbake: parse: Make include_all support empty variable expansions

2025-11-07T13:15:35+00:00

include and require support empty variable expansions, typically used with conditional expansions. However, include_all does not, and instead reports an error for the first path in BBPATH. Rewrite include_all so that its behavior matches include and require.

bitbake: parse/ast: add support for 'built-in' fragments

2025-06-20T11:03:37+00:00

When reviewing proposed fragments to add settings for DISTRO and MACHINE, RP noted that such fragments only add clutter and overhead, and there's no need to maintain them as separate files. Rather when bitbake sees 'fragmentvar/fragmentvalue' it can expand that into FRAGMENTVAR = "fragmentvalue". To achieve that, 'addfragments' directive is extended with a parameter that sets the name of the variable that holds definitions of such built-in fragments, for example like this: "machine:MACHINE distro:DISTRO" Then each enabled fragment name is matched against these definitions and the respective variable is set, e.g. 'machine/qemuarm' would match 'machine:MACHINE' and result in MACHINE set to 'qemuarm'. This happens before any fragment files are looked up on disk, and no such lookup happens if there was a match, which should prevent possible misuse of the feature. So the builtin fragment definition is also an allowlist for them. Please also see the patches for oe-core that show an application of the feature.

bitbake: parse/ConfHandler: Add warning for deprecated whitespace usage

2025-04-16T16:41:51+00:00

A lack of whitespace around variable assignment operators makes the files harder to read. There is a deeper issue in that a "+" character can sometimes be confused between the variable name and the assignment operator. Start showing warnings for such usage so we encourage people to use consistent whitespace which helps with file readability in general.

bitbake: parse: Forbid ambiguous assignments to ${.}, ${+}, and ${:} variables

2025-02-05T12:11:01+00:00

Old code that parse variable names in assignment commands behave differently for variables that ends with special symbol for single-character variable names and multi-character variable names. For example: A+="1" # Change variable ${A}, '+' glued to '=' A+ = "1" # Change variable ${A+} +="1" # Change variable ${+}, the '+' symbol not part of assignment operator + = "1" # Change variable ${+} New code would always assume that '.=', '+=', and ':=' is assignment operator. As result code like the following would raise parsing error +="value" While code with extra spaces would work as before + = "value" # Change variable ${+} This change allow to catch issues in code that generate bitbake configuration files in a manner like "echo ${VARNAME}+=${VALUE} >> conf/local.conf" (Bitbake rev: 93059aad13a12cd69d86368795c88e5349197d5d) Signed-off-by: Nikolai Merinov Signed-off-by: Richard Purdie

bitbake: parse: Add include_all conf file directive

2024-12-17T11:48:25+00:00

In some cases it would be helpful to be able to have an include file in a standard location which is included in all layers that are added to the system. The intent is for these to provide configuration tweaks of specific types so that a given file pattern can be adopted more widely for such configuration. The code will search for any named configuration file within BBPATH, so a configuration directive of: include_all conf/distro/include/myinc.conf would include the myinc.conf file in that subpath if present in any directory in BBPATH. Multiple files will be included if present. (Bitbake rev: d01d5593e7829ac60f37bc23cb87dc6917026471) Signed-off-by: Richard Purdie

bitbake: bitbake: parse: add support for flagged fragment variables

2024-12-13T10:44:35+00:00

It was suggested that using flags in fragment content to mark fragment-specific metadata (such as descriptions and dependencies) is prone to quiet regressions when fragments are renamed or moved, and it clutters the fragment content. With this change allowed fragment metadata variables must be explicitly listed in a variable that is given to addfragment directive, and parser will add the flag containing the fragment name to them.

bitbake: parse: add support for 'addfragments' directive

2024-12-08T22:36:11+00:00

It takes two parameters: - location prefix for fragments - name of variable that holds the list of enabled fragments, each of them prefixed by layer id Implementation of this directive essentially expands the fragment list obtained from the variable into absolute fragment paths and hands them to the implementation of 'require'.

bitbake: parse/ConfHandler: allow / in variable flags

2024-12-08T22:36:11+00:00

This is beneficial for config fragments, as their names are specified via flags, and those names can include slashes: BB_CONF_FRAGMENT_SUMMARY[init/systemd] = "This fragment enables systemd as an init manager" (Bitbake rev: 80805988492b35593067230f68782a5687c8f557) Signed-off-by: Alexander Kanavin Signed-off-by: Richard Purdie

bitbake: bitbake: ConfHandler: Allow variable flag name with a single character

2023-04-13T11:01:45+00:00

Update regex pattern to allow variable flag name with a single character. Regression tests have also been updated in `bb.parse` and `bin/bitbake-selftest -k ParseTest` has been successfully executed. Eliminate a trailing space as well. (Bitbake rev: bb9e523291a3cad6e1596ee6a1e715b5e5feba8f) Signed-off-by: Kai Kang Signed-off-by: Richard Purdie
