[ptxdist] Proper quoting of semicolons in URLs

[Dennis.Herbrich@hytera.de]

Good day, everyone!

When using ptxdist to "get" a package with an URL with semicolons in it, 
for example a snapshot from a gitweb repo, anything after the first 
semicolon
is interpreted as options to wget. Unfortunately I was unable to find a 
quoting
style that prevented this while still handing over a usable URL to wget:

An example for an URL I want to use:
http://git.xilinx.com/?p=linux-xlnx.git;a=snapshot;h=04d9378881401e71f83b8b4fea0abd71d33b4052;sf=tgz

I'm using ptxdist 2013.01.90 and copied the original kernel.make to my 
project
rules, with a custom KERNEL_URL. I tried these variations, and got the 
following
(slightly cleaned) results:

"Naive":
KERNEL_URL              := 
http://git.xilinx.com/?p=linux-xlnx.git;a=snapshot;h=04d9378881401e71f83b8b4fea0abd71d33b4052;sf=tgz

$ ptxdist-2013.01.90 print KERNEL_URL
http://git.xilinx.com/?p=linux-xlnx.git;a=snapshot;h=04d9378881401e71f83b8b4fea0abd71d33b4052;sf=tgz
$ ptxdist-2013.01.90 get kernel
ptxdist: error: invalid option 'a=snapshot' to ptxd_make_get_http


"Doublequoting":
KERNEL_URL              := 
"http://git.xilinx.com/?p=linux-xlnx.git;a=snapshot;h=04d9378881401e71f83b8b4fea0abd71d33b4052;sf=tgz"

$ ptxdist-2013.01.90 print KERNEL_URL
http://git.xilinx.com/?p=linux-xlnx.git
(This downloads an obviously unwanted HTML index page)


"Singlequoting":
KERNEL_URL              := 
'http://git.xilinx.com/?p=linux-xlnx.git;a=snapshot;h=04d9378881401e71f83b8b4fea0abd71d33b4052;sf=tgz'

$ ptxdist-2013.01.90 print KERNEL_URL
'http://git.xilinx.com/?p=linux-xlnx.git;a=snapshot;h=04d9378881401e71f83b8b4fea0abd71d33b4052;sf=tgz'
$ ptxdist-2013.01.90 get kernel
Could not download package
URL: 
'http://git.xilinx.com/?p=linux-xlnx.git;a=snapshot;h=04d9378881401e71f83b8b4fea0abd71d33b4052;sf=tgz'


Using backslashes to escape the semicolons does not work, either, same 
behaviour
as in "Naive".

Using urlencoding as in 
KERNEL_URL              := 
http://git.xilinx.com/?p=linux-xlnx.git%3Ba=snapshot%3Bh=04d9378881401e71f83b8b4fea0abd71d33b4052%3Bsf=tgz
would technically work with ptxdist, but gitweb doesn't seem to decode 
this,
 and throws a 404, which seems broken by itself. :(

Does anybody have a suggestion how to quote semicolons in my URL properly,
lest they are passed literally to wget instead of being split into 
options?
Is there some $(call verbatim,FOO) macro, perchance?

Thanks!
