Hey folks.
I also need Apache::Upload for a mod_perl script, and upgrading seemed like the
only way to go about it. I downloaded the patch that Blair provided, but
unfortunately, things did not go as easily as I might have hoped.
What follows is an explanation of what I went through to get this thing to
package. You can skip down a bit if you just want a recipe of what I did.
I unpacked libapreq2-2.04_03-dev.tar.gz (as obtained from Apache) and Blair's
patch applied cleanly (with -p1). However, attempting to dpkg-buildpackage it
resulted in lots of errors having to do with modperl_ types. I tried for a
while to figure out what was wrong and pretty much gave up, deciding instead to
see if I could just compile the apache supplied tar.gz.
It didn't take me long to realize that, due to Debian's Apache 2 being named,
well, apache2 (and not httpd), the configure script was somewhat confused. No
problem; changing a line in acinclude.m4 and rerunning the buildconf script
fixed this. Manually inspecting Blair's patch showed that he did this too. I
then went ahead and perl Makefile.PL'd the sucker and watched the compilation
messages shoot by.
Until I was greeted with an error regarding a missing modperl_ include file. I
had expected this, because of what Blair said, so following his lead I went
ahead and built debian's supplied modperl2 locally on my machine (no problems
there) and then copied over the requisite files. I then restarted the make and
all was well: complilation completed, and make test passed all tests. Whew!
Having done that, I figured that I should be able to simply take the debian/
related files out of Blair's patch and copy them into the source archive,
dpkg-buildpackage, and all would be well. I was very wrong about this.
It turns out that while the source archive will compile once, make distclean
(after having copied in the modperl_ include files) will *not* clean the tree
sufficiently to allow compilation again. In fact, the errors I got using
Blair's patch were exactly the ones I got trying to make distclean && make --
and sure enough, inspection of his patch noted that he had included the
various modperl_ include files. Blair, if you're reading this, explaining in
more detail how exactly you went about getting this son of a bitch to compile
would greatly sate my curiosity.
At any rate, once I figured this out, I realized I could automate the entire
build process by simply altering the debian/rules file to allow make to fail
once, and then copy all the modperl_ headers in, and then restart the build.
But because (for reasons I don't fully understand) copying in the header files
in totally mucks up the build if you try to make distclean && make, the rules
file can build only once.
Since dpkg-buildpackage will first debian/rules build and then
debian/rules binary, this meant that while it would build correctly the first
time, binary would actually go ahead and rebuild it, for whatever reason. So
I nuked the "build" predep on the binary-arch: rule, and switched my invoking
command to dpkg-buildpackage -rfakeroot -B -us -uc. It then built correctly,
but failed during installation.
It turns out that the Makefile in the env/ subdirectory of the package uses
apxs to install the module. This command completely ignores the DESTDIR
variable passed to make, meaning that apxs2 doesn't play nice and it actually
tries to install the module directly into /usr/lib/apache2 instead of into
$(TMP)/usr/lib/apache2 as it ought to.
My solution to this was to create a bin directory, and use perl to write
wrappers around cp, chmod, ranlib, and grep to ensure that any absolute paths
passed as arguments to these functions would be relocated to the $(TMP)
directory.
Make install then completed successfully, and doing it with dpkg-buildpackage
worked as well.
Ok, here it is, in steps.
1. Make a temp directory. Mine was /home/atp/pkgs/temp, if you see that
anywhere, replace it with your temp directory.
2. Download Blair's patch and put it in that directory.
3. Download libapreq2-2.04_03-dev.tar.gz from Apache's website.
4. apt-get source libapache2-mod-perl2
5. Build mod perl2 (cd into the directory and type:
dpkg-buildpackage -rfakeroot -us -uc
You may need to install some of the build-depends packages to do this.)
6. In your temp directory, make a directory called incs, and then do
cp -p /path/to/libapache2-mod-perl2-1.999.20/src/modules/perl/*.h \
/path/to/your/temp/dir/incs
7. You can delete the modperl source and related files now if you'd like to.
8. Extract the debian/ control files from Blair's patch. There are lots of
ways to do this. I did it with an ed script (assuming your pwd is the
temp dir):
mkdir debian && for i in \
$(grep '^diff.*debian' 2.04-patch.txt | cut -f 3 -d ' '); do \
f=$(basename $i); echo "$f"; \
(echo "/$(echo "$i" | sed 's@/@\\/@g')/d"; echo "ka"; \
echo ".,/^diff/s/^+//"; echo "'a+3,.-1p"; echo "q") | \
ed -s 2.04-patch.txt > debian/$f; \
done
All that does it take out the patches in the debian subdirectory. You
could do it by hand, but I'm much too lazy to do that.
9. Make the debian/rules script executable:
chmod 755 rules
10. Now, in your temp dir, mkdir bin, and create a perl script called
fix_arguments.pl. Because it's a rather long script, I've placed it
at the end of this e-mail. Make the script executable:
chmod 755 fix_arguments.pl
11. In the bin directory, do
for i in cp chmod grep ranlib; do ln -s fix_arguments.pl $i; done
You should now have 4 symlinks in this dir, all linked to fix_arguments.pl.
12. Now, in the debian subdirectory of your temp dir, patch the rules file. I
did this with an ed script again:
(echo '[EMAIL PROTECTED]([EMAIL PROTECTED]"`pwd`/../bin:\$\$PATH" &@'; \
echo '45s/ build//'; echo '32a'; \
echo -e '\011-$(MAKE) OPTIMIZE="$(OPTIMIZE)" LD_RUN_PATH=""'; \
echo -e '\011$(CP) -p ../incs/*.h src/'; echo '.'; echo '17a'; \
echo 'ifndef CP'; echo 'CP = /bin/cp'; echo 'endif'; echo; \
echo '.'; echo 'w') | ed -s rules
13. Ok, now create the build-clean script (which I've attached below) in your
temp directory. Make it executable (chmod 755 build-clean).
At this point, your temp directory should look like this:
/path/to/your/temp/directory/
2.04-patch
bin/
chmod -> fix_arguments.pl
cp -> fix_arguments.pl
fix_arguments.pl <- executable!
grep -> fix_arguments.pl
ranlib -> fix_arguments.pl
build-clean <- executable!
debian/
apreq.load
changelog
compat
control
copyright
dirs
rules <- executable!
shlibs
incs/
lots of modperl_ include files
libapreq2-2.04_03-dev.tar.gz
Ok, if you copied everything in correctly, type ./build-clean at the prompt.
It should build and package the sucker.
Note: after doing this whole process, I ar -x'ed the produced deb file and
greped for my home directory, to make sure that none of the binaries have
any references to my home dir. One did; /usr/lib/apache2/modules/mod_apreq.a.
Note that this file is not even present in 2.03, for whatever reason. Messing
around with objdump, I discovered that this string is present in in the
.debug_str section. I'm not sure what this is for (though I presume it's for
debugging, heh). The command to dump this data is
objdump -j .debug_str -s mod_apreq.a
Probably should pipe it through less. My home directory was stored around line
0760. I suppose I'll find out if this is a problem soon enough.
Ok, the files. Remember to edit the $DIR variable in fix_arguments.pl to
point to the actual location of your home dir.
