[Debian-med-packaging] Bug#992725: gbp:error: More than one archive specified. Try --help.

Package: routine-update
Version: 0.0.6
Severity: important

Hi Andreas,

when working on making sure the python-biopython watch file was
appropriately fixed, I saw routine-update choke with the
following error:

	$ routine-update
	gbp:info: Fetching from default remote for each branch
	gbp:info: Branch 'master' is already up to date.
	gbp:info: Branch 'pristine-tar' is already up to date.
	gbp:info: Branch 'upstream' is already up to date.

	uupdate: ../python-biopython-1.79+dfsg directory exists.
	uupdate: remove ../python-biopython-1.79+dfsg directory.
	uupdate: -> Overwrite to python-biopython_1.79+dfsg-1.debian.tar.xz
	[master dcb2e9f] routine-update: New upstream version
	 1 file changed, 3 insertions(+), 2 deletions(-)
	gbp:error: More than one archive specified. Try --help.

Adding `set -x` at the top of the routine-update script, I see
that uscan_out catches an additionall line dpkg-source which
matches with subsequent filtering:

	+ uscan_out='uscan info: Last orig.tar.* tarball version (from debian/changelog): 1.78+dfsg
	uscan info: Last orig.tar.* tarball version (dversionmangled): 1.78
	uscan info: New orig.tar.* tarball version (oversionmangled): 1.79
	Successfully repacked ../python-biopython-179.tar.gz as ../python-biopython_1.79+dfsg.orig.tar.xz, deleting 2 files from it.
	uscan info: New orig.tar.* tarball version (after mk-origtargz): 1.79+dfsg
	dpkg-source: info: unpacking python-biopython_1.79+dfsg.orig.tar.xz'

	++ echo 'uscan info: Last orig.tar.* tarball version (from debian/changelog): 1.78+dfsg
	uscan info: Last orig.tar.* tarball version (dversionmangled): 1.78
	uscan info: New orig.tar.* tarball version (oversionmangled): 1.79
	Successfully repacked ../python-biopython-179.tar.gz as ../python-biopython_1.79+dfsg.orig.tar.xz, deleting 2 files from it.
	uscan info: New orig.tar.* tarball version (after mk-origtargz): 1.79+dfsg
	dpkg-source: info: unpacking python-biopython_1.79+dfsg.orig.tar.xz'

	++ grep '.orig.tar.[bgx]z2*'

	++ sed 's#^.* \(\.\./[^ ]*\.orig\.tar\.[bgx]z2*\).*#\1#'

Ultimately leading to a faulty tarball name which is passed as
such to `gbp import-orig`, hence the "More than one archive
specified" error:

	+ tarball='../python-biopython_1.79+dfsg.orig.tar.xz
	dpkg-source: info: unpacking python-biopython_1.79+dfsg.orig.tar.xz'

routine-update 0.0.6 is around for quite some time, so I believe
it is a specific combination of watch option which might trigger
this, or simply a recent update somewhere else in the tooling.
Just in case, the corresponding watch file is:

	version=4
	
	opts="\
	filenamemangle=s%(?:.*?)?v?(\d[\d.]*)\.tar\.gz%@PACKAGE at -$1.tar.gz%,\
	uversionmangle=s/b/~b/;s/(\d)(\d+)/$1.$2/,\
	repacksuffix=+dfsg,\
	dversionmangle=s/\+dfsg//,\
	repack,\
	compression=xz" \
		https://github.com/biopython/biopython/tags \
		(?:.*?/)?biopython[v-]?(\d[\d.]*)\.tar\.gz debian uupdate

Complementing the `grep` command here over with the following
pattern might help:

	grep '\.\./.*.orig.tar.[bgx]z2*'

For information,
Have a nice day,  :)
Étienne.

PS: Note the debsums error is caused by the `set -x` added on
    top of the script.
