Usage: ./findversion.sh
|
|
Finds the current revision and if the code is modified.
|
|
|
|
Output: <REV>\t<REV_NR>\t<MODIFIED>\t<CLEAN_REV>
|
|
REV
|
|
a string describing what version of the code the current checkout is
|
|
based on. The exact format of this string depends on the version
|
|
control system in use, but it tries to identify the revision used as
|
|
close as possible (using the svn revision number or hg/git hash).
|
|
This also includes an indication of whether the checkout was
|
|
modified and which branch was checked out. This value is not
|
|
guaranteed to be sortable, but is mainly meant for identifying the
|
|
revision and user display.
|
|
|
|
If no revision identifier could be found, this is left empty.
|
|
REV_NR
|
|
the revision number of the svn revision this checkout is based on.
|
|
This can be used to determine which functionality is present in this
|
|
checkout. For trunk svn checkouts and hg/git branches based upon it,
|
|
this number should be accurate. For svn branch checkouts, this
|
|
number is mostly meaningless, at least when comparing with the
|
|
REV_NR from other branches or trunk.
|
|
|
|
This number should be sortable. Within a given branch or trunk, a
|
|
higher number means a newer version. However, when using git or hg,
|
|
this number will not increase on new commits.
|
|
|
|
If no revision number could be found, this is left empty.
|
|
MODIFIED
|
|
Whether (the src directory of) this checkout is modified or not. A
|
|
value of 0 means not modified, a value of 2 means it was modified.
|
|
Modification is determined in relation to the commit identified by
|
|
REV, so not in relation to the svn revision identified by REV_NR.
|
|
|
|
A value of 1 means that the modified status is unknown, because this
|
|
is not an svn/git/hg checkout for example.
|
|
|
|
CLEAN_REV
|
|
the same as REV but without branch name
|
|
|
|
By setting the AWK environment variable, a caller can determine which
|
|
version of "awk" is used. If nothing is set, this script defaults to
|
|
"awk".
