META-INFO
Meta-information is generally for OpenFOAM internal use only.
The format, content and meaning may be changed at anytime without prior notice. If any of these are changed, these are some of places that will need to be updated accordingly:
- bin/foamEtcFile
- bin/tools/foamConfigurePaths
- bin/tools/foamPackRelease
- etc/openfoam
- wmake/scripts/wmake-build-info
api-info
This file and its contents are to be tracked by git.
- File content (api) generated by
wmake -build-infofrom theOPENFOAMdefine inwmake/rules/General/general - File content (patch) is manually generated content.
build-info
This file is never to be tracked by git, but may be present in shipped source archives.
- File content (branch, build) generated by
wmake -build-infofrom git information and cached from previous wmake (api)
Content types
api
Format: date +%y%m
- 4-digit year-month (YYMM) integer corresponding to the major
release or in unusual cases an intermediate release.
Example,
2106for the June-2021 release.
patch
Format: date +%y%m%d
- 6-digit year-month-day (YYMMDD) integer corresponding to a patch-level for the given released API.
- The first release can have a patch value of
0or1which indicates that it is unpatched or just released. Alternatively it can have a patch value corresponding to the release date.
The patch value is only meaningful together with the api value.
However, for development branches, the patch level should not be
ascribed too much meaning, but will often correspond to the last
merge with a maintenance (eg, master) branch.
Flow of information
Changes in the build information must be reflected in information available in the final binaries. Conversely, it is necessary for later distributions to have a record of the same information.
| property | source | saved |
|---|---|---|
| api | wmake/rules | api-info |
| patch | manual (api-info) | build-info |
| branch | git | build-info |
| build | git | build-info |
The command wmake -build-info -check is used to determine if
the saved information needs synchronization. The command
wmake -build-info -update performs the synchronization.
Notes
The saved information is split into two separate files.
The api-info file contains more permanent information,
whereas the build-info is more transient in nature.
