+
+Good morning Guix developers,
+
+C-Lightning is one of the earliest living implementations of the Lightning
+Network protocol.
+I am one of the developers of this implementation.
+
+I tested this as follows:
+
+* Extracted the package `c-lightning` into a `c-lightning.scm` file.
+* Ran `guix build --rounds=3D4 -f c-lightning.scm` on an X86-64 server to
+  check for reproducability issues.
+* Ran the compiled `lightningd` with `lightningd --version`,
+  `lightningd --help`, and the developer-secret undocumented
+  `lightningd --test-daemons-only` and checked they work correctly.
+* Ran the compiled `lightningd` with `lightningd --proxy=3D127.0.0.1:9050
+  --bind-addr=3D127.0.0.1:9735 --addr=3Dstatictor:127.0.0.1:9051
+  --always-use-proxy=3Dtrue` on a server with Bitcoin and Tor installed,
+  and checked that it indeed created an LN wallet and started operating
+  the node.
+  * This also tests the SQLITE database backend and that the sub-daemons
+    are accessible and runnable.
+* From an existing Lightning Network node, did a `lightning-cli connect`
+  to the new node running on the above command, and confirmed that the
+  above new node was connected to, and that it started downloading the
+  gossip map (the first thing every new node does when it initially gets
+  connected to the network).
+* On a separate X86-64 machine with the same Guix commit version, copied
+  the `c-lightning.scm` file and reran `guix build --rounds=3D4 -f
+  c-lightning.scm` as well.
+* Checked that the same `/gnu/store` path was produced on the separate
+  machine as on the first test server.
+* Checked that this command produced the exact same text on both computers:
+  `find ${GNU_STORE_PATH} -type f | sort | xargs -n1 sha256sum`.
+* Extracted the package `c-lightning-postgresql` into a
+  `c-lightning-postgresql.scm` file.
+* Ran `guix build --rounds=3D4 -f c-lightning-postgresql.scm` on a X86-64
+  server to check for reproducibility issues.
+* Chekced that `strings ${GNU_STORE_PATH}/bin/lightningd` for the
+  `c-lightning-postgresql` had references to `PQ*` functions, and that
+  the `c-lightning` version had none, meaning that `c-lightning-postgresql`
+  indeed included PostgreSQL support.
+
+Thus, PostgreSQL support is not fully tested yet, but I believe the
+produced binaries will work correctly as a C-Lightning instance.
+Therefore I would like to submit this patch for inclusion into Guix.
+
+Some notes:
+
+* C-Lightning includes an extensive suite of tests, but these require
+  several additional python packages, some of which (e.g.
+  `python-bitcoinlib`) are not yet in Guix.
+  The tests are extensive and *very long*, running the entire test
+  suite can take an hour or more depending on exact settings.
+* I took advantage of the functional nature of Guix and disabled the
+  relative-path `BINTOPKGLIBEXECDIR`, making it an absolute path, as
+  it also incidentally solves the issue of "upgrading C-lightning may
+  cause strange problems in a running instance".
+  See patch for more details.
+* Our `configure` and `Makefile` are weird and I should probably go
+  fix those upstream.
+
+Regards,
+ZmnSCPxj

+
+Good morning Guix developers,
+
+C-Lightning is one of the earliest living implementations of the Lightning
+Network protocol.
+I am one of the developers of this implementation.
+
+I tested this as follows:
+
+* Extracted the package `c-lightning` into a `c-lightning.scm` file.
+* Ran `guix build --rounds=3D4 -f c-lightning.scm` on an X86-64 server to
+  check for reproducability issues.
+* Ran the compiled `lightningd` with `lightningd --version`,
+  `lightningd --help`, and the developer-secret undocumented
+  `lightningd --test-daemons-only` and checked they work correctly.
+* Ran the compiled `lightningd` with `lightningd --proxy=3D127.0.0.1:9050
+  --bind-addr=3D127.0.0.1:9735 --addr=3Dstatictor:127.0.0.1:9051
+  --always-use-proxy=3Dtrue` on a server with Bitcoin and Tor installed,
+  and checked that it indeed created an LN wallet and started operating
+  the node.
+  * This also tests the SQLITE database backend and that the sub-daemons
+    are accessible and runnable.
+* From an existing Lightning Network node, did a `lightning-cli connect`
+  to the new node running on the above command, and confirmed that the
+  above new node was connected to, and that it started downloading the
+  gossip map (the first thing every new node does when it initially gets
+  connected to the network).
+* On a separate X86-64 machine with the same Guix commit version, copied
+  the `c-lightning.scm` file and reran `guix build --rounds=3D4 -f
+  c-lightning.scm` as well.
+* Checked that the same `/gnu/store` path was produced on the separate
+  machine as on the first test server.
+* Checked that this command produced the exact same text on both computers:
+  `find ${GNU_STORE_PATH} -type f | sort | xargs -n1 sha256sum`.
+* Extracted the package `c-lightning-postgresql` into a
+  `c-lightning-postgresql.scm` file.
+* Ran `guix build --rounds=3D4 -f c-lightning-postgresql.scm` on a X86-64
+  server to check for reproducibility issues.
+* Chekced that `strings ${GNU_STORE_PATH}/bin/lightningd` for the
+  `c-lightning-postgresql` had references to `PQ*` functions, and that
+  the `c-lightning` version had none, meaning that `c-lightning-postgresql`
+  indeed included PostgreSQL support.
+
+Thus, PostgreSQL support is not fully tested yet, but I believe the
+produced binaries will work correctly as a C-Lightning instance.
+Therefore I would like to submit this patch for inclusion into Guix.
+
+Some notes:
+
+* C-Lightning includes an extensive suite of tests, but these require
+  several additional python packages, some of which (e.g.
+  `python-bitcoinlib`) are not yet in Guix.
+  The tests are extensive and *very long*, running the entire test
+  suite can take an hour or more depending on exact settings.
+* I took advantage of the functional nature of Guix and disabled the
+  relative-path `BINTOPKGLIBEXECDIR`, making it an absolute path, as
+  it also incidentally solves the issue of "upgrading C-lightning may
+  cause strange problems in a running instance".
+  See patch for more details.
+* Our `configure` and `Makefile` are weird and I should probably go
+  fix those upstream.
+
+Regards,
+ZmnSCPxj

+Hello!
+
+Thanks for the patch!
+
+I built it and it was successful, however, few comments:
+
+The various hacks in the recipe to get a working build seem troublesome
+maintenance-wise, is it possible you think since you are a developer
+that you make the build scripts a bit more standard in the project?
+
+I see there's some vendored libraries: gheap, jsmn, libbacktrace,
+libsodium, libwally-core ; Is it possible to unvendor those and create
+separate packages for each of them? Or is there a requirement of strict
+behavior here, either way, you could also create separate packages for
+each of them even if those are specific to c-lightning. It would make
+the main recipe cleaner, since as far as I can see it's also why the
+build system is so stubborn to GNU Guix? That it also attempts to build
+vendored libraries?

+Good morning Leo,

+
+Already working on that, but 0.10.0 will release soon and I doubt my change=
+s will make it by then, so Guix might get c-lightning to 0.10.1 or later if=
+ we wait for it.
+
+> I see there's some vendored libraries: gheap, jsmn, libbacktrace,
+> libsodium, libwally-core ; Is it possible to unvendor those and create
+> separate packages for each of them? Or is there a requirement of strict

+> each of them even if those are specific to c-lightning. It would make
+> the main recipe cleaner, since as far as I can see it's also why the
+> build system is so stubborn to GNU Guix? That it also attempts to build
+> vendored libraries?
+
+I think it is more the custom `configure` script.
+The custom `configure` script also compiles a ***C*** program that then gen=
+erates the configuration for the `ccan` library of the project, meaning cro=
+ss-compilation requires special work for C-Lightning.
+And `configure` does not call `configure` of the included libraries as well=
+.
+
+Yes, it is true that there is something of a requirement of a strict behavi=
+or here, I suppose it is possible to use `git-fetch` instead of `url-fetch`=
+ for our external libraries.
+How do I generate `guix hash` for `git-fetch`ed `source`s?
+However it also means that every release of C-Lightning I have to go double=
+-check what git commit to use for each library (though `jsmn` and `libbackt=
+race` at least seem very stable).
+
+But it looks to me that unvendoring will require more extensive patching of=
+ the `Makefile` and an even larger maintenance burden on Guix side?
+
+`libwally-core` itself depends on another library `libsecp256k1`, so I supp=
+ose it must transitively be unvendored as well.
+
+> Additionally, please do enable the test suite it's really valuable in
+> GNU Guix.
+
+The test suite is fairly large and can take a significant amount of time to=
+ run in full.
+
+In addition, part of the test includes checks which take advantage of `BINT=
+OPKGLIBEXECDIR` relative path we normally use, which I want to disable for =
+Guix at least since the relative path only has an advantage if the user wan=
+ts to move the installation after-the-fact to a different location (and on =
+Guix the "installation" path cannot be moved anyway).
+Using an absolute `BINTOPKGLIBEXECDIR` gives an advantage as mentioned in t=
+he comments that a profile being upgraded from one version of C-Lightning t=
+o another does not cause problems for daemons currently running off the pro=
+file.
+The test can be disabled (but not easily), I suppose.
+
+> I can help packaging the necessary Python dependencies, also we have a
+> Python importer, e.g. "$ guix import pypi -r <pkg>" to help us go
+> faster at it.
+
+Please do, I am not very familiar with any Python infrastructure and am pri=
+marily a C programmer here, I just barely hack together some kind of test i=
+n Python.
+

+Unvendoring is more or less a policy because we must be able to audit
+each piece of software separately for freedom issues (licenses,
+violations to the GNU FSDG), and it eases work for security-patching
+also.
+

+>
+> Yes you can use git-fetch, to make sure we are on the same page, are

+> consensus code?
+
+Well we need to produce signatures and transactions that pass Bitcoin Core =
+signature validation at least, so it is best to use a version of `libsecp25=
+6k1` (which produces signatures) that we know works, as well as `libwally-c=
+ore` (which produces transactions).
+I would personally use the `libsecp256k1` version that `libwally-core` vend=
+ors in as well, since there may be specific interactions between `libwally-=
+core` and `libsecp256k1` that may be different if we use the Bitcoin Core v=
+ersion of `libsecp256k1`.
+
+For `libsodium`, at least the hashing has to work correctly, but I think it=
+ is simple enough that strict behavior requirements are not so onerous.
+Indeed, we usually get this from the OS (but we need a later feature than t=
+hat available on some old Ubuntu versions, which is why it got vendored in)=
+, so I should probably "just" add it as an input.

+
+I understand.
+
+This will require a largish amount of work I think.
+
+Would this technique be acceptable?
+
+* `add-before 'configure 'unvendor-externals`
+  * `rm -rf` the vendored externals.
+  * `ln -s` the needed `.h` and `.la`/`.a`/`.so` files from the `inputs` to=
+ the expected paths within the `external/` directory.

+That would not be simple I think, but let me see what can be done.
+For one, it would be fairly difficult to test it outside of a patched Guix,=

+he libbacktrace we use (Debian ships a libbacktrace for android development=
+, and is not the same package as what we use).
+Of the external packages we use, only libsodium is available on Debian (and=

+ "we can use the system version", because all the others are not available =
+on most systems.
+
+Also --- we would be somewhat wary of taking the "system" `libsecp256k1`, a=
+s this is very consensus-critical, and we know that our program works with =
+a very specific version, but cannot assure this to be true if the "system" =
+`libsecp256k1` is not the exact version.
+(Note that we cannot take the `libsecp256k1` from `bitcoin-core` because (1=

+ and (2) the interface `bitcoin-core` uses may be different from the interf=
+ace we use, it would require review before we would be able to assure that =
+the interfaces they use are exactly the same; this would be mitigated by ru=

+Is there an easy way to ensure that any `libsecp256k1` that gets fed into t=

+We can package every of those in GNU Guix, there's not as much
+bureaucracy as Debian when it comes to inclusion, as long as Free
+Software and freedom-non-controversial. The "system" thing is just so
+handy for us build-system wise we can just provide it as an input and
+it will find things automatically, I don't say that "system" lookup
+should imply to take any available library in general, in the context

+Debian's who can't have or with great difficulty, multiple versions of
+the same library installed.

+
+We can package every of those in GNU Guix, there's not as much
+bureaucracy as Debian when it comes to inclusion, as long as Free
+Software and freedom-non-controversial. The "system" thing is just so
+handy for us build-system wise we can just provide it as an input and
+it will find things automatically, I don't say that "system" lookup
+should imply to take any available library in general, in the context
+of GNU Guix we can give it a particular version and stick to it, unlike
+Debian's who can't have or with great difficulty, multiple versions of

+
+Okay.
+
+It is somewhat unclear to me however how to discover where the library is l=
+ocated.
+As far as I understand how autotools does it, it looks at some standard loc=
+ations on `/`, but I am uncertain if that is how it actually works.
+
+For example if `libwally-core` is separately packaged, obviously it would i=
+nstall into a `/gnu/store/*` via a `--prefix` override.
+And if the dependent package were using autotools, it is somehow able to ma=
+gically find where the `lib*.a` file is.
+However, C-Lightning does not actually use autotools (its build system pred=
+ated my participation, I offered to port to autotools but this was declined=
+), so I somehow need to emulate what autotools does in `--use-system-librar=
+ies` mode.
+
+I probably have to go hack some autotools package that trivially depends on=
+ `libwally-core` and see what the exact shell script is generated.
+
+> Also if we want to provide the Python bindings (?) to c-lightning we
+> also have the option of creating a separate package based on the same
+> sources but with different build-system (like python-build-system), and
+> also it can have c-lightning as an input.
+
+Note that AFAIK the Python bindings do not actually invoke any of the C-Lig=
+htning binaries, they just open the UNIX socket to the c-lightning daemon, =
+so I think there is no need for `c-lightning` itself as an input.

+Hello!
+
+> Okay.
+>=20
+> It is somewhat unclear to me however how to discover where the
+> library is located.
+> As far as I understand how autotools does it, it looks at some
+> standard locations on `/`, but I am uncertain if that is how it
+> actually works.
+>=20
+> For example if `libwally-core` is separately packaged, obviously it
+> would install into a `/gnu/store/*` via a `--prefix` override.
+> And if the dependent package were using autotools, it is somehow able
+> to magically find where the `lib*.a` file is.
+> However, C-Lightning does not actually use autotools (its build
+> system predated my participation, I offered to port to autotools but
+> this was declined), so I somehow need to emulate what autotools does
+> in `--use-system-libraries` mode.
+>=20
+> I probably have to go hack some autotools package that trivially
+> depends on `libwally-core` and see what the exact shell script is
+> generated.
+
+pkg-config if your deps provide .pc files! Otherwise I am actually not
+sure of the lookup strategies.
+
+> Note that AFAIK the Python bindings do not actually invoke any of the
+> C-Lightning binaries, they just open the UNIX socket to the c-
+> lightning daemon, so I think there is no need for `c-lightning`
+> itself as an input.
+
+Alright!
+

+Just for your information, I am quite busy on a GNOME upgrade now, we
+have the 1.2.1 release soon also, some security issues to solve, I told
+you earlier I would help but at the end I think it may come a bit later
+rather than sooner. Hang out on the IRC channel #guix on Freenode for
+more real-time collaboration if that's of interest to you!

+Just for your information, I am quite busy on a GNOME upgrade now, we
+have the 1.2.1 release soon also, some security issues to solve, I told
+you earlier I would help but at the end I think it may come a bit later
+rather than sooner. Hang out on the IRC channel #guix on Freenode for
+more real-time collaboration if that's of interest to you!

+
+Good morning Guix developers,
+
+C-Lightning is one of the earliest living implementations of the Lightning
+Network protocol.
+I am one of the developers of this implementation.
+
+I tested this as follows:
+
+* Extracted the package `c-lightning` into a `c-lightning.scm` file.
+* Ran `guix build --rounds=3D4 -f c-lightning.scm` on an X86-64 server to
+  check for reproducability issues.
+* Ran the compiled `lightningd` with `lightningd --version`,
+  `lightningd --help`, and the developer-secret undocumented
+  `lightningd --test-daemons-only` and checked they work correctly.
+* Ran the compiled `lightningd` with `lightningd --proxy=3D127.0.0.1:9050
+  --bind-addr=3D127.0.0.1:9735 --addr=3Dstatictor:127.0.0.1:9051
+  --always-use-proxy=3Dtrue` on a server with Bitcoin and Tor installed,
+  and checked that it indeed created an LN wallet and started operating
+  the node.
+  * This also tests the SQLITE database backend and that the sub-daemons
+    are accessible and runnable.
+* From an existing Lightning Network node, did a `lightning-cli connect`
+  to the new node running on the above command, and confirmed that the
+  above new node was connected to, and that it started downloading the
+  gossip map (the first thing every new node does when it initially gets
+  connected to the network).
+* On a separate X86-64 machine with the same Guix commit version, copied
+  the `c-lightning.scm` file and reran `guix build --rounds=3D4 -f
+  c-lightning.scm` as well.
+* Checked that the same `/gnu/store` path was produced on the separate
+  machine as on the first test server.
+* Checked that this command produced the exact same text on both computers:
+  `find ${GNU_STORE_PATH} -type f | sort | xargs -n1 sha256sum`.
+* Extracted the package `c-lightning-postgresql` into a
+  `c-lightning-postgresql.scm` file.
+* Ran `guix build --rounds=3D4 -f c-lightning-postgresql.scm` on a X86-64
+  server to check for reproducibility issues.
+* Chekced that `strings ${GNU_STORE_PATH}/bin/lightningd` for the
+  `c-lightning-postgresql` had references to `PQ*` functions, and that
+  the `c-lightning` version had none, meaning that `c-lightning-postgresql`
+  indeed included PostgreSQL support.
+
+Thus, PostgreSQL support is not fully tested yet, but I believe the
+produced binaries will work correctly as a C-Lightning instance.
+Therefore I would like to submit this patch for inclusion into Guix.
+
+Some notes:
+
+* C-Lightning includes an extensive suite of tests, but these require
+  several additional python packages, some of which (e.g.
+  `python-bitcoinlib`) are not yet in Guix.
+  The tests are extensive and *very long*, running the entire test
+  suite can take an hour or more depending on exact settings.
+* I took advantage of the functional nature of Guix and disabled the
+  relative-path `BINTOPKGLIBEXECDIR`, making it an absolute path, as
+  it also incidentally solves the issue of "upgrading C-lightning may
+  cause strange problems in a running instance".
+  See patch for more details.
+* Our `configure` and `Makefile` are weird and I should probably go
+  fix those upstream.
+
+Regards,
+ZmnSCPxj
