hi all...
about 2 weeks ago I noticed that modules with DIR_CREATE and DIR_MERGE
sections stopped working with bleedperl. I've tried to trace it as best I
could, but I'm really at a loss since Apache just stops - no core.
sending httpd -X to strace gives me
open("/src/bleedperl/lib/site_perl/5.7.1/i686-linux-thread-multi/Apache/Stop
Me.pm", O_RDONLY|O_LARGEFILE) = 4
fstat(4, {st_mode=S_IFREG|0444, st_size=579, ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0)
= 0x405b6000
read(4, "package Apache::StopMe;\n\nuse 5.7"..., 4096) = 579
read(4, "", 4096) = 0
close(4) = 0
munmap(0x405b6000, 4096) = 0
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++
no matter which module I happen to be using - if it has DIR_CREATE and
DIR_MERGE sections (or SERVER_*) it SIGSEGVs. modules that use custom
directives but without merging seem to be fine.
I have included a simple module for testing. on my system (cvs Apache, cvs
modperl, bleedperl with 2 vhosts)
PerlModule Apache::StopMe
StopMe
in the main server config is sufficient to stop things. maybe I'm chasing
air here, but it just all of a sudden stopped working. I'm at a loss for
how to continue tracking it down (if 'it' actually exists :)
