Would you guys be able to give the latest ndctl and pmdk packages from
https://launchpad.net/~canonical-server/+archive/ubuntu/nvdimm/ a test
run? I'm currently proposing them for an SRU into bionic, and it would
be best to catch any issues before it hits the bionic-proposed pocket.

[Marcin Ślusarz]

In pmdk 1.4.1 NDCTL_ENABLE controls daxio only, so it's safe to build
pmdk with this flag. The default value has been flipped to "detect", so
if ndctl is installed in the system, there's no need to set it
explicitly.

Should I enable ndctl now with pmdk 1.4.1 and get the daxio utility, or
not yet?

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Andreas Hasenack]

Do you have a preference for which version we should backport to bionic? Cosmic 
has these currently:
pmdk: 1.4 (latest upstream is 1.4.1)
ndctl: 60.1 (latest upstream is 61.2)

In general the latest is usually what people want, but I thought best to
check. Maybe there is something super important we are missing, or
something experimental that we do not want yet.

Keeping in mind that if want to update these, they need to be updated in
cosmic first, and then pushed down to bionic.

[Marcin Ślusarz]

util_file_create timed out because you used file system
(PMEM/NON_PMEM_FS_DIR) that does not support fallocate syscall. glibc's
posix_fallocate falls back to writing zeroes when fallocate is not
supported, so test takes ages to complete.
https://github.com/pmem/pmdk/pull/2939 adds code to detect it and fail
early.

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Marcin Ślusarz]

I'm looking into util_file_create failure.

WRT pcheck, you had hit some bug in our build system. I know what's causing the 
error you are seeing (make tries to build pmemspoil twice, both processes write 
to the same file, which means creation of corrupted object file and that leads 
to failure in linking), but I don't know where is the bug yet. I'll look into 
this.
To work around it run "make test" first and only then use pcheck with -jX.

Without parallelization it worked:

# make check (and pcheck, for parallel check) actually runs it
dh_auto_test -- SKIP_SYNC_REMOTES=y
make SKIP_SYNC_REMOTES=y check

21min to build with that in a VM. Not too bad. I'll add that to the
package and skip the test if it's building in a lxc container.

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Marcin Ślusarz]

jemalloc: We can't upstream those changes, because jemalloc changed too
much since we forked it. pmemcto makes this even harder problem, because
any changes to jemalloc on-media layout would have to invalidate pmemcto
pools and we don't have any mechanism to automatically do that.

testing: Default configuration uses non-pmem code path, which is slow.
You can disable it (unset NON_PMEM_FS_DIR), enable pmem path
(PMEM_FS_DIR) and if you don't have DAX available set
PMEM_FS_DIR_FORCE_PMEM to 1. I'd also recommend disabling tests for
static libraries (TEST_BUILD="debug nondebug") and use "pcheck" target
with -j$(($(nproc)*2)) instead of "check" (it doesn't support -j
option).

FYI, yesterday I pushed some changes to the 1.4 branch to make it
possible to run in-tree tests against installed libraries. Those changes
will be part of 1.4.1 release.

Would you also recommend a minimal testing.sh file to run at least some
of the pmdk unit tests during build? The build environment is usually a
VM, but could be an unprivileged lxd container as well. As we speak I'm
giving a try with the supplied testing.sh.example one (renamed to
testing.sh)

Another review point came up: do you still need the bundled jemalloc

3.6.0. Are these changes not worth pushing back upstream?

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Andreas Hasenack]

They are considered documentation and trigger a lintian warning if not
installed: https://lintian.debian.org/tags/package-does-not-install-
examples.html

Thanks for the NDCTL warning, I won't enable it.

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Marcin Ślusarz]

If you want to disable building examples you have to remove both
examples and benchmarks from src/Makefile ALL_TARGETS/RELEASE_TARGETS.

BTW, why do you even need to that? Why are they included in development
packages?

Please don't build pmdk 1.4 with NDCTL_ENABLE=y. This variable enables
much more than daxio and we are not ready to support that yet.

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Andreas Hasenack]

Question: should I build pmdk with ndctl support, i.e., with the daxio
package? Set NDCTL_ENABLE=y?

When I do that, however, for some reason libpmemobj and others get RPATH
set again, even though I'm passing NORPATH=1:

Right :/

I was trying to find a way to not build the examples, but even removing
the "examples" directory from src/Makefile didn't do it, something else
kept triggering its build. Do you have a tip on how I can avoid building
the examples?

Not a big issue, but I don't think shipping object files and Visual

Makefiles are not self-contained (they source Makefile.inc, which is not
included in the package)

I made no attempt at creating an upgrade path from the nvml-named
packages. If you were using them before, I suggest to purge them and
reinstall these instead.

Packaging 1.4 sounds great :). You don't need to do anything for
Valgrind support in 1.4.

Nobody had considered that libvmmalloc.so would not be available. Our tests use 
libvmalloc.so (that's how I found this issue - 
https://github.com/pmem/pmdk/pull/2873) and today I found out that even our 
libvmmalloc man page tells you to use libvmmalloc.so.
I'll fix both issues on PMDK side.

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Andreas Hasenack]

I'm almost done packaging 1.4, as per comment #51. We would prefer to
stick with 1.4 unless you object. Keeping in mind that upgrading to 1.4
after 1.3.1 is released into bionic would be much harder, as it changes
the source name.

With that in mind, do I need any changes in 1.4 regarding what you said
about valgrind? Of course, you haven't seen my packages yet, but in
principle?

About the LD_LIBRARY_PATH issue with debug builds, why would you set
LD_PRELOAD to the libfoo.so symlink (instead of libfoo.so.1), even when
using pmdk (formelly nvml) installed from source? Just because "it
works" and then you don't have to remember the major lib version, or
update docs whenever that changes? .so symlinks are not meant to be used
as runtime libraries, but I can appreciate it's a bit convenient.

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Marcin Ślusarz]

One more issue which I haven't noticed earlier - missing Valgrind
support.

Bit of background: PMDK supports both regular upstream Valgrind tools 
(memcheck, helgrind and drd) and  our pmemcheck tool (available at 
https://github.com/pmem/valgrind).
To enable support for all tools you have to use EXTRA_CFLAGS="-DUSE_VALGRIND" 
option for make. We know that no distribution will package our special version 
of Valgrind, so we made an option to build PMDK with support for the upstream 
tools only, but it requires listing them all:
EXTRA_CFLAGS="-DUSE_VG_MEMCHECK -DUSE_VG_HELGRIND -DUSE_VG_DRD"

In 1.4 we fixed this by incorporating Valgrind headers into the tree and 
enabling support for all tools without any flag, independent of installed 
Valgrind version. If someone would want to use pmemcheck they would have to 
build our Valgrind fork, without rebuilding PMDK.
Eventually we will upstream pmemcheck, but that's a long term activity.

In the mean time, for 1.3 packages I'd suggest to go with just upstream
Valgrind tools.

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Marcin Ślusarz]

I tested ~ppa18 with PMDK in-tree tests and I realized that removal of .so 
files from nvml_dbg directory we discussed earlier breaks the assumption that 
you can just set LD_LIBRARY_PATH and everything will work correctly WHEN 
libvmmalloc is involved.
This works:
LD_PRELOAD=libvmmalloc.so ./app
This doesn't:
LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/nvml_dbg LD_PRELOAD=libvmmalloc.so 
./app
Of course you can set LD_PRELOAD to libvmmalloc.so.1, but it's a bit annoying 
that you have to do that when library built from source works as intended...

As the upstream has change the project name to `pmdk` we will be
changing the source package to match.  If there are any objections,
please speak now. :)

There was some toolchain change in ubuntu bionic in the past few days that 
broke the build:

https://lists.ubuntu.com/archives/ubuntu-devel/2018-April/040289.html

I don't know yet what that is about, so I disabled some example building
in the meantime. I've seen in the logs that some examples are still
built, but at least the failure doesn't happen anymore.

~ppa18 is my new Ubuntu Archive Admin review candidate, which I will
submit shortly. It would be great if you could give it another round of
testing.


I'll now switch back to ndctl and bring that one into compliance.

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Andreas Hasenack]

I've been working on more lintian fixes raised by the AA review. Here is 
today's batch:
nvml (1.3.1-0ubuntu1~ppa12) bionic; urgency=medium

  * Install pmemobj docs into a html subdir
  * Enable parallel build (dh $@ --parallel)
  * Several lintian fixes:
- binary-control-field-duplicates-source
- duplicate-short-description
- extended-description-is-probably-too-short
- restore lintian override about ldconfig for the debug libraries, but
  this time in the -debug packages and not -dev packages.
- using-first-person-in-description
- extended-description-is-probably-too-short
- debian-watch-does-not-check-gpg-signature
- d/p/spelling-fixes.patch: assorted spelling fixes
- useless-autogenerated-doxygen-file
- hardening-no-bindnow


That last one, hardening-no-bindnow, meant I changed the build flags. This is 
what is used now:
CPPFLAGS   : -Wdate-time -D_FORTIFY_SOURCE=2 -D_GNU_SOURCE -D_REENTRANT
CFLAGS : -g -O2 
-fdebug-prefix-map=/home/ubuntu/nvdimm/nvml/nvml-git=. -fstack-protector-strong 
-Wformat -Werror=format-security -std=gnu99 -Wall -Werror -pthread 
-DSRCVERSION="debian/1.3.1-0ubuntu1_ppa5-92-g79c0594" -O2 -U_FORTIFY_SOURCE 
-D_FORTIFY_SOURCE=2 -DJEMALLOC_LIBVMEM -fvisibility=hidden
LDFLAGS: -Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,-z,now 
-Wl,-z,relro -Wl,--fatal-warnings


Before it was:
CPPFLAGS   : -Wdate-time -D_FORTIFY_SOURCE=2 -D_GNU_SOURCE -D_REENTRANT
CFLAGS : -g -O2 
-fdebug-prefix-map=/home/ubuntu/nvdimm/nvml/nvml-git=. -fstack-protector-strong

-D_FORTIFY_SOURCE=2 -DJEMALLOC_LIBVMEM -fvisibility=hidden
LDFLAGS: -Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,-z,relro 
-Wl,--fatal-warnings

(don't mind the version, that's just in my local builds)

There is another flags-related lintian warning that I have to address:
I: libvmem1-debug: hardening-no-fortify-functions 
usr/lib/x86_64-linux-gnu/nvml_dbg/libvmem.so.1.0.0

But since this is about the debug libraries, I think I will just add a
note to READBE.source and/or override it.

nvml (1.3.1-0ubuntu1~ppa11) bionic; urgency=medium

  * Create missing .version file based on the upstream version listed in
the debian/changelog topmost entry.

That should work for a build from a directory that is not a git

For now you can create .version file in the top level directory. We are

I suspect a dh_* script just did the right thing once I moved the dbg
libraries to their own -debug packages.

What should I do to get the right version in the pkgconfig files?

We tracked one test failure in ppa7 version to debug libraries not
having symbols, but I see ppa10 already have them. I don't see it
mentioned in Changelog. What happened?

(obj_convert test injects crashes in some specific places using gdb and
see if consecutive open handles such pool correctly)

[Marcin Ślusarz]

I don't think there is a need for -dev-debug packages. The interface
between debug and release packages is the same by design, so nobody
should ever need to link to debug libraries.

Both debian/1.3.1-0ubuntu1_ppa5-43-g1b3d0af and nvml-1.3.1 are wrong. It
should say 1.3.1. It seems we'll have to create source packages with
.version file or keep it in tree.

I don't think versioning is working correctly when this is built from a
git tree that is not upstream. For example, I build this from my
packaging branch, and I get:

ubuntu@bionic-nvdimm:~$ pmempool --version
pmempool debian/1.3.1-0ubuntu1_ppa5-43-g1b3d0af

ubuntu@bionic-nvdimm:~$ cat /usr/lib/x86_64-linux-gnu/pkgconfig/libvmmalloc.pc

Description: libvmmalloc library from NVML project
Version: ${version}

We'll see what the PPA gets.

Ok, new layout done: https://pastebin.ubuntu.com/p/8bV9CWFy3r/

Pushing to the ppa:

nvml (1.3.1-0ubuntu1~ppa8) bionic; urgency=medium

  * Drop the manpage lintian override and fix the problem instead.
  * Create new -debug packages for the *_dbg/ libraries, document it
in README.source and drop the ldconfig lintian override.
  * Patch the devel manpages explaining that the extra debug libraries
are in the -debug packages.

There was no consideration done for the upgrade from previous versions
of these packages, you may have to remove and reinstall if you get
conflicts or stray files.

These are the git repositories I've been working with, I don't remember
if I mentioned this before:

nvml: https://code.launchpad.net/~ahasenack/ubuntu/+source/nvml/+git/nvml
ndctl: https://code.launchpad.net/~ahasenack/ubuntu/+source/ndctl/+git/ndctl

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Andreas Hasenack]

Hi Marcin,

I'm planning on splitting the *_dbg directories out into their own
packages. Including runtime libraries from /usr/lib/$ARCH/*_dbg/ in the
-dev package wasn't very popular.

I'm still working out the details, but it should be more or less like this 
(using libpmem as an example):
libpmem1: continues as is
libpmem-dev: no longer includes /usr/lib/x86_64-linux-gnu/nvml_dbg; has small 
patch to manpages explaining that nvml_dbg is in a new package in Ubuntu systems
libpmem1-debug: ships /usr/lib/x86_64-linux-gnu/nvml_dbg/lib*.so.*
libpmem-dev-debug: ships /usr/lib/x86_64-linux-gnu/nvml_dbg/{lib*.a,lib*.so} 
and requires libpmem1-debug

Is the separate dev package necessary? I.e., do you need the special
debug library build when linking with your applications and wanting the
extra logging? Or can apps keep linking against the normal library, and
just set LD_LIBRARY_PATH when they need extra logging? I assume the
latter, so the dev-debug package wouldn't be necessary.

Enjoy your holidays. I'm off on Friday (March 30th) but back on Monday.

I fixed this today. stable-1.3 fix:
https://github.com/pmem/pmdk/commit/5cbd2be4ae1ae7541da5975c9071fa36b53cd835

Testing those packages is taking longer than I expected. I'll report back as 
soon as I get the results.
However without minimum version check, pmemfile builds fine and its tests pass, 
so I don't expect full test suite will find anything.

(FYI, I'll be out of office until Wednesday)

This is actually a bug in NVML/PMDK. It seems nobody tried to use pkg-
config files with minimum version specified for packages built out of
git tree.

Temporarily you can work around it by creating ".version" file in the
top level directory with "1.3.1" as content.

I asked some people internally to test those packages. I think we'll get
results tomorrow.

While waiting on that I tried to build pmemfile project 
(https://github.com/pmem/pmemfile) and I got this:
-- Checking for module 'libpmemobj>=1.3'
--   Requested 'libpmemobj >= 1.3' but version of libpmemobj is 

This is because "version" field in all .pc files is empty.

The ndctl package is working for me, I verified listing namespaces and
converting namespaces between a few different modes.

The only cosmetic issue is that the version does not match the package
version. By default git-version tries to do the right thing based on the
tag, but if you're building without the git tree it may fall back to the
default defined version.

E.g.:

$ dpkg-query -l ndctl
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)

Hi,

it just occurred to me that we never had a comment in this bug about the
packaged software actually works correctly with the hardware it was
meant for.

Could you please add a comment here saying that these packages are
working correctly with your hardware? And that the devel packages are
correct in the sense that you can link your applications using them?

Thanks

Just pushed nvml 1.3.1-0ubuntu1~ppa7 to the PPA:

nvml (1.3.1-0ubuntu1~ppa7) bionic; urgency=medium

  * Add a lintian override for the manpages.
  * Add a lintian override for dev packages regarding ldconfig because of
the _dbg subdirectory.
  * Install docs for libpmemobj and fix its directory to match the package
name

The ldconfig lintian override is about the _dbg directory we talked
about. I don't know yet if an Archive Admin will accept that, we will
find out. I added links to this bug and to the issue you opened in
github.

I also renamed the libpmemobj++ documentation directory. The package is
named libpmemobj-dev, but make install was installing the docs to
/usr/share/libpmemobj++-dev/.

I'm going to check the debian/copyright file on ndctl now, I think it
needs a bit of work. I've seen at least one case where a file has an
lgpl license but d/copyright claims it's gpl.

I understand your concern, but I'd like to ask you to not remove it yet, 
because:
- it would make responding to bug reports and support requests a bit harder
- shipped man pages mention those libraries

But I think you are right, so I opened an issue with the proposal to get rid of

[Andreas Hasenack]

Would you expect end users to need the files from that nvml_dbg
directory?

In the current packaging, these go into the corresponding libfoo-dev
packaages, but that's not really correct from a packaging perspective.
At most they should be in some new package, something like libfoo-extra-
debugging-dev perhaps, but I found no precedence for such a thing.

Ubuntu already produces packages with debugging symbols for all builds,
so that aspect is covered and wouldn't be lost. What these won't have is
the extra logging, asserts and expensive checks that you mentioned,
which I assume cannot be enabled at runtime with an environment variable
for example.

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Marcin Ślusarz]

Files under nvml_dbg are builds with debugging symbols, logging, asserts
and expensive checks that we normally don't want users to run with.

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[Andreas Hasenack]

Hi, a question. What are the files under /usr/lib/$arch/nvml_dbg/ needed
for? They have debugging symbols? If yes, we already generate debugging
symbols in the ddeb packages, like:

$ dpkg --contents librpmem-dev-dbgsym_1.3.1-0ubuntu1~ppa6_amd64.ddeb
drwxr-xr-x root/root 0 2018-03-21 20:00 ./

[Andreas Hasenack]

I just pushed nvml_1.3.1-0ubuntu1~ppa6 to the ppa:
 nvml (1.3.1-0ubuntu1~ppa6) bionic; urgency=medium
 .
   * updated package descriptions
   * disable rpath
   * remove trigger for man-db
   * lintian: change location of bash completion file

Please test.

A big chunk of the remaining lintian errors are about copyrights. I'll
work on that next, and any feedback you may have so far.

New ndctl upload to the canonical-server PPA at https://launchpad.net
/~canonical-server/+archive/ubuntu/nvdimm/:

ndctl (59.2-0ubuntu1~ppa3) bionic; urgency=medium

  * Install pkgconfig files only in the -dev library packages
  * Don't install .la files, pkgconfig is preferred
  * lib*.so go into -dev packages, lib*.so.* into non-dev
  * Update long description in -dev packages
  * Append major soname version to non-dev library packages
  * Other lintian fixes


Please test.

I'll work on the nvml package now.

[Andreas Hasenack]

Hi,

we switched over to a team-owned PPA:

https://launchpad.net/~canonical-server/+archive/ubuntu/nvdimm/

ppa:canonical-server/nvdimm

Please use this one from now on. At this moment, they contain the latest
debs from Nish that I just re-uploaded there.


** Description changed:

  The support for Intel NVDIMM technology requires both kernel and
  userspace components.  The kernel components have landed in 4.15 and
  will be available in Bionic.  In order for users to take advantage of
  NVDIMMs in their deployments, the following userspace packages are also
  needed in Bionic:
  
  Libraries for accessing and manipulating NV Memory devices:
  
  libpmem -- basic pmem operations like flushing
  libpmemblk, libpmemlog, libpmemobj -- pmem transactions
  libvmem, libvmmalloc -- volatile use of pmem
  libpmempool -- persistent memory pool management
  librpmem -- remote access to persistent memory (EXPERIMENTAL)
  
  Source Code: https://github.com/pmem/nvml
  
  Tools for management of NV devices and device pools.
  
  pmempool -- standalone tool for off-line pool managementDescription:
  
  Source Code: https://github.com/pmem/pmdk/releases/tag/1.3.1
  
  ndctl -- Utility library for managing the libnvdimm (non-volatile memory
  device) sub-system in the Linux kernel.
  
  Source Code: https://github.com/pmem/ndctl

+ Please use this PPA for testing:

Not sure why "NVML ... library" is better than "NVML library for ..." :)

NVML:
1) Nope, for old packages only libpmem had this problem. Now it's even worse - 
none of the packages contain .so used for linking.
3) "detail" directory is still missing.
7) Already backported to stable-1.3 branch, will be part of 1.3.2:

You can see what we came up with here: 
https://github.com/pmem/pmdk/blob/stable-1.3/utils/build-dpkg.sh
"NVML library" was a common mistake. In 1.4 this will no longer be a problem, 
because we renamed NVML to PMDK (Persistent Memory Development Kit)

[Bug 1752378] Re: Please add Userspace Packages for NVDIMM support

[pragyansri.pa...@intel.com]

Update from NVML Team Testing from Marcin Slusarz:

Several issues found, some critical. List in severity order:
1)Libpmem-dev is not installable, because one of the files also exists in 
libpmem.

2)Libpmemobj-dev package doesn't install all C header files, making it
completely useless.

3)Libpmemobj C++ headers and documentation are not packaged at all.

4)Librpmem is not packaged.

5)Libpmemblk-dev, libpmemlog-dev, libpmempool-dev and libpmemobj-dev do
not depend on libpmem-dev (pkg-config files won't work correctly without
libpmem-dev).

6)Libraries are installed to /usr/lib instead of /usr/lib/x86_64-linux-
gnu/.

7)Pkg-config files in all -dev packages point to /usr/local.
This is actually a bug in pmdk, which we already fixed on master. I think it 
doesn't matter much, but it's worth backporting it for 1.3.2.

8)"NVML library" (NVM library library) in package descriptions looks a
bit silly.

9)Homepage points to github, instead of http://pmem.io/pmdk/.
