[pkg-go] ratt report for golang-blackfriday (1.2+git20150720.80.8cec3a8-1)

[Anthony Fok]

Hello Tianon, Martín and Paul:

Thank you for allowing me to upgrade the golang-blackfriday package
(for the sake of Hugo http://gohugo.io/ , hehe)

And Michael, thank you for creating ratt (“Rebuild All The Things!”).

golang-blackfriday-dev (now golang-github-russross-blackfriday-dev)
is used by two existing source packages, namely go-md2man and
dh-make-golang.

I am happy to report that Blackfriday’s latest upstream snapshot
dated 2015-07-20 passes the Debian ratt test:

Some notes from the experience (before I forget them):

 1. sbuild tends to just "hang there" without any error message.[1]
    I ran into the same problem, but got around it, thanks to the
    solution posted by Raphaël Hertzog,[2] by changing "--dist=sid"
    to "--dist=unstable" in my local copy of ratt.

    It seems the quick-start instructions at https://wiki.debian.org/sbuild
    configures for "unstable" rather than "sid", though I must admit
    I know little about sbuild, and I was only trying to get ratt
    up-and-running as fast as I could, so I didn’t dig into this.

    [2] https://lists.debian.org/debian-devel/2015/07/msg00654.html

 2. The package I used for the ratt test is _not_ the same as the one
    I uploaded, difference being the "ratt test" version has the
    "golang-blackfriday-dev" to "golang-github-russross-blackfriday-dev"
    rename reverted.  Otherwise, sbuild would have the old
    golang-blackfriday-dev (1.2-1) installed instead.

    (go-md2man depends only on golang-blackfriday-dev, whereas dh-make-golang
    depends on golang-blackfriday-dev | golang-github-russross-blackfriday-dev,
    favouring the old package.)

    In retrospect, my use of Conflicts/Provides/Replaces rather than the use
    of a dummy transitional package is probably the culprit, though I
    thought carrying a dummy transitional package is a bit of a burden
    and didn’t go that route.

Overall, the Debian "ratt" experience is awesome, and once sbuild is
configured properly, it is a rather fast and fun experience, taking
only 7 minutes for 2 packages.  I am especially with the buildlog reports
that sbuild generate.  They are comprehensive, and beautiful to look at.
Oooooooooooo!  (/me likes eye candies)

Cheers,

Anthony
