22 | # The following section is based on a similar feature in LTTng-tools. | |

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 | |
89e18e1e PP |
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. | |
578e048b | 48 | ## |
89e18e1e PP |
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. | |
