| 22 | # The following section is based on a similar feature in LTTng-tools. |
| 23 | |
| 24 | ## |
| 25 | ## This target generates an include file that contains the git version |
| 26 | ## string of the current branch, it must be continuously updated when |
| 27 | ## we build in the git repo and shipped in dist tarballs to reflect the |
| 28 | ## status of the tree when it was generated. If the tree is clean and |
| 29 | ## the current commit is tag a starting with "v", consider this a |
| 30 | ## release version and set an empty git version. |
| 31 | ## |
| 32 | ## Here is what the inline script does: |
| 33 | ## |
| 34 | ## First, delete any stale "version.i.tmp" file. |
| 35 | ## |
| 36 | ## If "bootstrap" and ".git" exists in the top source directory and the git |
| 37 | ## executable is available, get the current git version string in the form: |
| 38 | ## |
| 39 | ## "latest_tag"(-"number_of_commits_on_top")(-g"latest_commit_hash")(-dirty) |
| 40 | ## |
| 41 | ## And store it in "version.i.tmp", if the current commit is tagged, the tag |
| 42 | ## starts with "v" and the tree is clean, consider this a release version and |
| 43 | ## overwrite the git version with an empty string in "version.i.tmp". |
| 44 | ## |
| 45 | ## If we don't have a "version.i.tmp" nor a "version.i", generate an empty |
| 46 | ## string as a failover. If a "version.i" is present, for example when building |
| 47 | ## from a distribution tarball, get the git_version using grep. |
| 48 | ## |
| 49 | ## Fetch the BT_VERSION_EXTRA_NAME define from "version/extra_version_name" and output it |
| 50 | ## to "version.i.tmp". |
| 51 | ## |
| 52 | ## Fetch the BT_VERSION_EXTRA_DESCRIPTION define from "version/extra_version_description", |
| 53 | ## sanitize and format it with a sed script to replace all non-alpha-numeric values |
| 54 | ## with "-" and join all lines by replacing "\n" with litteral string c-style "\n" and |
| 55 | ## output it to "version.i.tmp". |
| 56 | ## |
| 57 | ## Repeat the same logic for the "version/extra_patches" directory. |
| 58 | ## Data fetched from "version/extra_patches" must be sanitized and |
| 59 | ## formatted. |
| 60 | ## The data is fetched using "ls" with an ignore pattern for the README.adoc file. |
| 61 | ## The sanitize step uses sed with a script to replace all |
| 62 | ## non-alpha-numeric values, except " " (space), to "-". |
| 63 | ## The formatting step uses sed with a script to join all lines |
| 64 | ## by replacing "\n" with litteral string c-style "\n". |
| 65 | ## |
| 66 | ## If we don't have a "version.i" or we have both files (version.i, version.i.tmp) |
| 67 | ## and they are different, copy "version.i.tmp" over "version.i". |
| 68 | ## This way the dependent targets are only rebuilt when the git version |
| 69 | ## string or either one of extra version string change. |
