Backslashes in file names in destroot cause activate to fail

[jpo@…]

Seems like a simple enough fix for anyone who is familiar with TCL and the base plumbing. I'm not unfortunately.

Consider the following:

PortSystem          1.0
name                backslash-test
version             1
categories          devel
platforms           darwin
description         tests backslashes in filenames for the activate target

fetch               {}
checksum            {}
use_configure       no
build               {}
destroot {
    touch "${destroot}${prefix}/share/back\\slash"
}

Which produces the following results

$ sudo port destroot backslash-test
--->  Fetching distfiles for backslash-test
--->  Verifying checksums for backslash-test
--->  Extracting backslash-test
--->  Configuring backslash-test
--->  Building backslash-test
--->  Staging backslash-test into destroot
$ find backslash-test -type f
backslash-test/work/.macports.backslash-test.state
backslash-test/work/destroot/opt/local/share/back\slash
$ sudo port install backslash-test
--->  Activating backslash-test @1_0

Please see the log file for port backslash-test for details:

Error: Processing of port backslash-test failed

I've attached a full log of an install of the above portfile from a clean state.

Btw, I found this while trying to port deco-archive (​http://hartlich.com/deco/archive/) which has a directory full of files named as regexes.

Hmm. I wish I could edit the original ticket since the

$ sudo port activate backslash-test
$ sudo port install backslash-test

was a copy-paste fail and not actually activate with no output.

In any case, the full log is still accurate.
