Description Joeri Capens 2009-10-21 06:54:01 UTC
Zsh fails to build on with USE=static on three different machines. After removing the USE option it compiles fine on all machines.

This error occurs with 4.3.9, 4.3.10 and perhaps older versions too.


Reproducible: Always

Steps to Reproduce:
1. echo "app-shells/zsh static" >> /etc/portage/package.use
2. emerge zsh
3.

Actual Results:  
make[2]: Entering directory `/var/tmp/portage/app-shells/zsh-4.3.9/work/zsh-4.3.9/Src'

Comment 3 SpanKY gentoo-dev 2010-08-15 06:38:22 UTC
Created attachment 243007 [details]
sb-sigsuspend.c

to reproduce:
gcc -static sb-sigsuspend.c
sandbox
./a.out
<hang>
Comment 4 SpanKY gentoo-dev 2010-08-15 20:12:42 UTC
so the case is basically:
 - static app (so we're ptracing it)
 - app registers a SIGCHLD handler
 - app does a fork()
 - parent waits for the child to exit
 - parent waits forever

this is because the ptrace code swallows all SIGCHLD events on the assumption that it's for us, not for the thing we're tracing.  i added this during the initial ptrace work for the explicit reason of ignoring SIGCHLD events for a process, but perhaps i didnt think things through enough.

i'll run some regression tests and package emerges, and if things still pass, just drop it and move on.

also, this doesnt affect zsh stabilization as the issue only happens with ~arch sandbox (stable sandbox doesnt support static app tracing).
Comment 6 Joeri Capens 2010-08-17 12:26:27 UTC
I'm not sure if Comment #2 and later are actually related to the problem I originally reported? In my case, the configure stage runs fine, it's the compile stage where things go wrong. Disabling sandbox does not make a difference, using sandbox-2.3 does not fix it either.

However, the original bug has actually been fixed in zsh-4.3.10-r1:

    *zsh-4.3.10-r1 (02 May 2010)

    02 May 2010; Torsten Veller <tove@gentoo.org> +zsh-4.3.10-r1.ebuild:
    EAPI=2. Depend on libpcre with USE=static-libs for a static build.

zsh-4.3.10-r1 and zsh-4.3.9 compile fine with USE=static after libpcre has been compiled with USE=static-libs.

I guess the the "libpcre with USE=static-libs" dependency should be added to zsh-4.3.9(-r1) ? Or perhaps it's time to stabilize >=zsh-4.3.10-r1 ?
Comment 7 Joeri Capens 2010-08-17 12:30:47 UTC
By the way, the title of this bug used to be "app-shell/zsh fails to build with USE=static"
Comment 8 SpanKY gentoo-dev 2010-08-17 12:34:03 UTC
use the clone link to resubmit and re-review

you need to post your config.log and a full build.log as an attachment when you do though
