'''Update the <release> tag in resources/freedesktop/org.wireshark.Wireshark.metainfo.xml
|
|
|
|
According to https://www.freedesktop.org/software/appstream/docs/chap-Metadata.html
|
|
the <releases/> tag in resources/freedesktop/org.wireshark.Wireshark.metainfo.xml should contain release
|
|
information sorted newest to oldest.
|
|
|
|
As part of our release process, when we create release tag x.y.z, we tag
|
|
the next commit x.y.z+1rc0, e.g.
|
|
|
|
v3.0.0 2019-02-28 release tag
|
|
v3.0.1rc0 2019-02-28 next commit after v3.0.0
|
|
v3.0.1 2019-04-08 release tag
|
|
v3.0.2rc0 2019-04-08 next commit after v3.0.1
|
|
|
|
Find a list of release versions based on our most recent rc0 tag and
|
|
update the <releases/> section of resources/freedesktop/org.wireshark.Wireshark.metainfo.xml accordingly.
|
|
Assume that the tag for the most recent release doesn't exist and use
|
|
today's date for it.
