+ <youpi> uh, the i686 profiles have much more progression than i386
+ <youpi> it seems they don't actually run these
+ <pinotree> youpi: what do you mean with "we don't run those"?
+ <pinotree> iirc there are three build profiles done, but there are 4
+ regression test files
+ <youpi> yes, but some failing tests are not run in the three build profiles
+ <youpi> even if they are built for all of them
+ <pinotree> not even run? which ones?
+ <youpi> see for instance test-ifloat.out
+ <youpi> test-ifloat is built in all profiles, but only run in the libc one
+ <pinotree> don't have a glibc built tree around atm, sorry :/
+ <youpi> perhaps because glibc thinks it's not useful to run it again if it
+ fails on i386
+ <youpi> you can check the logs
+ <pinotree> do you think glibc's build system is that smart? :)
+ <pinotree> all the builds are done in separate builddirs, so theorically
+ they should not touch each other...
+ <youpi> yes
+ <youpi> that's why I'm surprised
+ <pinotree> could it be they get not run in optimized/particular builds?
+ <pinotree> what about linux/kfreebsd i386?
+ <youpi> I don't see what makes them not run
+ <youpi> or at least be treated particularly by th eMakefile
+ <youpi> not run on kfreebsd either
+ <youpi> pinotree: also, most of the tests now working have been marked as
+ failing by your patches for 2.17, would it be possible to retry them on
+ the box you used at that time?
+ <pinotree> that's the vm on my machine
+ <youpi> which kind of vm?
+ <youpi> kvm?
+ <pinotree> y
+ <youpi> they are working here
+ <youpi> with kvm
+# Building
+Run `debian/rules patch` to apply patches (instead of having it done during the
+build). Then you can edit files manually.
+Several passes: `libc`, `i686`, `xen`; `EGLIBC_PASSES='libc i686'`, etc.
+If building with `EGLIBC_PASSES=libc` (more specifically, without `xen`), the
+`libc0.3-dev_extra_pkg_install` rule in `debian/sysdeps/` will
+fail. (Same for `libc6-dev_extra_pkg_install` in `debian/sysdeps/`, for
+example.) Why is this special handling only done for `xen`, but not for
+> Samuel: Historically because it's done that way in linux-i386. I don't know
+> the real reason.
+Do `export LC_ALL=C` before building, otherwise the testsuite/make error
+messages will be different from those stored in the
+`debian/testsuite-checking/expected-results-*` files, resulting in a spurious
+build failure.
+Run `debian/rules build-arch DEB_BUILD_OPTIONS=parallel=2 [EGLIBC_PASSES=...]`
+to build (or `build` instead of `build-arch` to build the arch-independent
+stuff, too). Can interrupt with `C-c` during locale stuff or testsuite if only
+interested in the build tree.
+Run `fakeroot debian/rules binary DEB_BUILD_OPTIONS=parallel=2
+[EGLIBC_PASSES=...]` to build Debian packages or `binary-arch` for just the
+architecture-dependent ones.
+The latter two steps can also be combined as `dpkg-buildpackage -R'debian/rules
+EGLIBC_PASSES=libc' -nc -b -uc`. `-nc` will prevent the *clean step* which
+would first try to un-patch, which may conflict if you have done any edits
+apter applying patches.
+If the Debian symbol versioning file is not up to date and the build of Debian
+packages fails due to this, putting `DPKG_GENSYMBOLS_CHECK_LEVEL=0` in the
+environment \`\`helps''; see `man dpkg-gensymbols`.
+# IRC, freenode, #hurd, 2013-07-01
+ <braunr> something seems to have changed with regard to patch handling in
+ eglibc 2.17
+ <braunr> pinotree: when i add a patch to series and use dpkg-buildpackage,
+ i'm told there are local modifications and the build stops :/
+ <braunr> any idea what i'm doing wrong ?
+ <pinotree> which steps do you do?
+ <braunr> i extract the sources, copy the patch to debian/patches/hurd-i386,
+ add the appropriate line to debian/patches/series, call dch -i, then
+ dpkg-buildpackage
+ <pinotree> eglibc is a "3.0 (quilt)" format source package
+ <pinotree> this means its default patches are in a quilt-style system, and
+ they are applied on extraction
+ <braunr> ok
+ <braunr> and it can't detect new patches ?
+ <pinotree> so if you add a new patch to the global serie, you have to push
+ it manually
+ <braunr> i have to revert them all ?
+ <braunr> ok
+ <braunr> how do i do that ?
+ <pinotree> quilt push -a
+ <braunr> ok
+ <braunr> thanks
+ <pinotree> remember to do that before starting the build, since the rest
+ assumes the quilt-style patches are fully applied
+ <bddebian> No push applies them, quilt pop -a reverts them
+ <pinotree> yeah, and he has to push the new over the dpkg-applied ones
+ <bddebian> Oh, aye
+ <braunr> does quilt change series ?
+ <pinotree> no
+ <braunr> ok
+ <pinotree> i mean, some commands do that
+ <braunr> so i do everything i did, with an additional push, right ?
+ <pinotree> ok, screw me, i didn't get your question above :P
+ <braunr> does that change your answer ?
+ <pinotree> <braunr> does quilt change series ?
+ <braunr> yes
+ <pinotree> if you import or create a new patch, it changes series indeed
+ <braunr> ok
+ <pinotree> push or pop of patches does not
+ <braunr> i'm doing it wron
+ <braunr> g
+ <pinotree> btw, in a quilt patch stack you can easily import a new patch
+ using the import command
+ <pinotree> so for example you could do
+ <pinotree> apt-get source eglibc # or get it somehow else
+ <pinotree> cd eglibc-*
+ <pinotree> quilt import /location/of/my/patch
+ <pinotree> quilt push # now your patch is applied
+ <braunr> ah thanks
+ <pinotree> dpkg-buildpackage as usual
+ <braunr> that's what i was looking for
+ <bddebian> quilt new adds a new entry in series
+ <pinotree> y
+ <bddebian> or import, aye
+ <pinotree> braunr: if you want to learn quilt, a very good doc is its own,
+ eg /usr/share/doc/quilt/quilt.txt.gz
+ * bddebian has never actually used import
+ <braunr> ok
+ <pinotree> it is basically a simple stack of patches
+ <youpi> braunr: yes, patch handling is a bit different
+ <youpi> the arch-independant patches are applied by dpkg-source -x
+ <youpi> and the arch-dependent patches are applied during build
