#68446: sourcehut portgroup: project name should be included in default distname
------------------------+-----------------------
 Reporter:  ryandesign  |      Owner:  (none)
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.8.1
 Keywords:              |       Port:  sourcehut
------------------------+-----------------------
 The sourcehut portgroup sets this default distname:

 {{{#!tcl
     git.branch              [join
 ${sourcehut.tag_prefix}]${sourcehut.version}[join ${sourcehut.tag_suffix}]
 }}}
 {{{#!tcl
     default distname        {${git.branch}}
 }}}

 This is not suitable because it does not include the project name.

 This is the reason why, in [https://distfiles.macports.org/go/ the go
 directory of the distfiles server], which contains the distfiles of
 numerous projects that are written in the go language, we have numerous
 distfiles whose names are only the version number with no indication of
 what project they belong to:

 * 0.2.1.tar.gz (kiln)
 * 0.3.0.tar.gz (kiln)
 * 0.3.1.tar.gz (kiln)
 * 0.3.2.tar.gz (kiln)
 * 0.4.0.tar.gz (kiln)
 * v0.3.0.tar.gz (hut)
 * v0.3.4.tar.gz (ijq)
 * v0.3.5.tar.gz (ijq)
 * v0.3.6.tar.gz (ijq)
 * v0.3.8.tar.gz (ijq)
 * v0.4.0.tar.gz (ijq)
 * v0.4.1.tar.gz (ijq)

 Worse, this could lead to conflicts in the future if any of those projects
 ever reach a version number any of the other projects had ever reached.

 Use a default distname that includes the project name, like kiln-0.2.1 or
 hut-v0.3.0. If the sourcehut service doesn't offer a URL that provides
 such a file, fake it with a [wiki:PortfileRecipes#fetchwithgetparams dummy
 GET parameter] like the github portgroup does.
