Bug 1310704

This is present in RHEL-6 too.
In RHEL-7 it has been fixes as bug 1225118

+++ This bug was initially created as a clone of Bug #1045723 +++

%autosetup -pN parsing doesn't terminate at EOL but continues to read the next line. For example this and foo.patch:

    %autosetup -p1
    echo hello

...results in this rpmbuild error:

    + /usr/bin/cat [...]/foo.patch
    + /usr/bin/patch -p1 -secho hello
    /usr/bin/patch: invalid option -- 'h'

Reproducer srpm attached.

Right, this looks like an off-by-one'ish thing with parametrized macros. The effect is reproducable with just this:

--
%define foo(x) echo "FOO"

%foo -x
echo hello
--

If %foo is "called" with -x, "hello" ends up on the same line, otherwise it goes on a line of its own. I'll have a closer look when back at work next week, but the behavior seems to be ages old (present in rpm 4.4.x too)

--- Additional comment from Ville Skyttä on 2013-12-27 12:13:35 EST ---

IIRC I've always ended parametrized macro definitions with %{nil}, don't remember exactly why but I suppose it could have been in order to avoid this very issue.

--- Additional comment from Panu Matilainen on 2014-01-02 08:41:13 EST ---

Yeah, %{nil} at end avoids the issue, and given all the quirks in macro processing people just tend to use whatever gets the job done, whether the whatever makes sense or not.

For added fun, merely adding a trailing space is enough to trigger this "behavior" too, ie '%foo ' will also cause the newline to be silently eaten away. I've a preliminary fix for it, the remaining question is whether there are people actually relying on that longstanding quirk.

Fixed upstream now: http://rpm.org/gitweb?p=rpm.git;a=commitdiff;h=1bdcd0500865efd3566efd7f951228f69b58e755

I guess I'd better stick that into rawhide rpm and see what blows up :)

FYI, this just went into rawhide as of rpm-4.11.2-3, lets see what (if anything) happens...

This change breaks many macros used by Java packages

Macro definition (see also [1]):

%pom_xpath_inject()   %{expand: %{__pom_call}xpath_inject   %*
}

Macro call (see also [2]):

# use java 5 generics in modello plugin
%pom_xpath_inject "pom:plugin[pom:artifactId[text()='modello-maven-plugin']]"\
"/pom:executions/pom:execution/pom:configuration" \
"<useJava5>true</useJava5>" doxia-modules/doxia-module-fml/pom.xml

macro expansion diff between rpm 4.11.2-2 and 4.11.2-3:

There's new line added which breaks the code.

So, that'd be ... a macro argument with a literal line-continuation in it, or something like that. Eep.

I've reverted the change while I scratch my with this.

I also faced this bug when trying to use %autosetup -S git. :P

--- Additional comment from Panu Matilainen on 2014-08-19 05:29:55 EDT ---

FWIW this should be now fixed in F21 + rawhide, in a way that doesn't break the Java macros.

--- Additional comment from Fedora End Of Life on 2015-01-09 17:23:05 EST ---

This message is a notice that Fedora 19 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 19. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 19 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

--- Additional comment from Jaroslav Reznik on 2015-03-03 11:57:43 EST ---

This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.
