>From reading the debian bug report, it seems like there is considerable discussion that still needs to happen separate from debian or ubuntu packaging. Additionally, this seems to not be an issue in debian, once they update nodejs in the debian repository to the latest version.
So, I'll ignore upstream and debian discussion and changes, since that seems to be ongoing, and IIUC won't impact whatever change we make to nodejs in ubuntu (for current releases). Also, I'll mark this bug as affecting only bionic (and possibly cosmic, since debian hasn't yet updated nodejs to 0.10). For trusty and xenial, again IIUC, nodejs is built with the correct openssl so this ABI mismatch problem doesn't exist there. > NodeJS 8.10.0 officially comes with OpenSSL 1.0.2n I think this is an important piece of info here, and I wasn't able to find any "official" documentation that clearly states this - can you provide a link to any docs for this? I'm not disputing it, but if we're going to rebuild nodejs with a different openssl version it would be good to be able to point to upstream docs to justify it. > if you want to reproduce it, you simply need to npm install grpc on Ubuntu > using > Ubuntu's nodejs. Loading and using gRPC (I can build a quick nodejs demo > project if you want) yes, please - I'm not familiar with nodejs or npm, so while I can do 'sudo apt install nodejs ; sudo npm install grpc ; git clone https://github.com/nicolasnoble/openssl-nodejs-ubuntu-demo', I'm not entirely sure what exactly to do after that to reproduce this. It's important (or at least, very helpful) to have specific clear steps to reproduce and verify the bug, and verify the fixed package (even to those not familiar with nodejs/npm). Also, I've built nodejs for bionic in this ppa, altering the build and runtime deps to use bionic's openssl1.0 and libssl1.0-dev; can you test with this build and see if it fixes the problem? https://launchpad.net/~ddstreet/+archive/ubuntu/lp1779863 ** Also affects: nodejs (Ubuntu Cosmic) Importance: Undecided Status: New ** Also affects: nodejs (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: nodejs (Ubuntu Trusty) Importance: Undecided Status: New ** Also affects: nodejs (Ubuntu Xenial) Importance: Undecided Status: New ** Changed in: nodejs (Ubuntu Trusty) Status: New => Invalid ** Changed in: nodejs (Ubuntu Xenial) Status: New => Invalid ** Changed in: nodejs (Ubuntu Bionic) Status: New => In Progress ** Changed in: nodejs (Ubuntu Cosmic) Status: New => In Progress ** Changed in: nodejs (Ubuntu Bionic) Importance: Undecided => Medium ** Changed in: nodejs (Ubuntu Cosmic) Importance: Undecided => Medium ** Changed in: nodejs (Ubuntu Bionic) Assignee: (unassigned) => Dan Streetman (ddstreet) ** Changed in: nodejs (Ubuntu Cosmic) Assignee: (unassigned) => Dan Streetman (ddstreet) -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial. Matching subscriptions: Ubuntu 16.04 Bugs https://bugs.launchpad.net/bugs/1779863 Title: Ubuntu nodejs package isn't ABI compatible with mainline nodejs. Status in nodejs package in Ubuntu: In Progress Status in nodejs source package in Trusty: Invalid Status in nodejs source package in Xenial: Invalid Status in nodejs source package in Bionic: In Progress Status in nodejs source package in Cosmic: In Progress Status in nodejs package in Debian: New Bug description: Background: NodeJS has a native extension API: https://nodejs.org/api/addons.html It's fairly understood by developers that NodeJS's ABI is stable, and that one module built using a version of nodejs should work on another semantically version compatible of nodejs. NodeJS exposes various third party libraries to the native module developers. Quote from the addons developers page: "Node.js includes a number of other statically linked libraries including OpenSSL. These other libraries are located in the deps/ directory in the Node.js source tree. Only the libuv,i OpenSSL, V8 and zlib symbols are purposefully re-exported by Node.js and may be used to various extents by Addons." It's fairly understood by developers that native modules have the same ABI guarantee than the rest of the node API. The NodeJS ecosystem uses native modules extensively, and it's fairly common for developers to publish precompiled versions of their extensions so that the typical end-user can simply npm install their dependencies without worrying about having a compiler installed. Some packages will do their own thing (see for instance https://www.npmjs.com/package/uws), while others will rely on third party extensions to facilitate their work. See for instance prebuild (https://www.npmjs.com/package/prebuild) that has a handful of dependents, or node-pre-gyp (https://www.npmjs.com/package/node-pre- gyp) that has north of 350 dependents. So the nodejs ecosystem has roughly 400 native packages that are publishing prebuilt versions of their extensions. Problem with the Ubuntu nodejs package: Put simply, it breaks prebuilt packages that depend on OpenSSL. NodeJS 8.10.0 officially comes with OpenSSL 1.0.2n, while the NodeJS 8.10.0 that comes with the Ubuntu package exposes OpenSSL 1.1.0g. Since there are ABI breakages between OpenSSL 1.0.2 and 1.1.0, these ABI breakages are bubbling up to any prebuilt native addon. Here is an example: https://github.com/nicolasnoble/openssl-nodejs-ubuntu-demo If you build this package under the mainline nodejs, it will try to import the following symbols from OpenSSL 1.0.2: . SSL_library_init . SSLeay_version Whereas if you build it under Ubuntu's nodejs, it will try to import the following symbols instead from OpenSSL 1.1.0: . OPENSSL_init_ssl . OpenSSL_version Therefore, trying to load one prebuilt module from one version of the runtime to another will result in a symbol loading error: node: symbol lookup error: /home/pixel/node-openssl-addon- example/build/Release/openssl_example.node: undefined symbol: SSL_library_init Incidentally, nodejs 10.5.0 uses OpenSSL 1.1.0h, and compiling the same demo module with this version of node will try to import the proper symbols. Obviously, since the module will be built for the wrong version of the nodejs runtime, it won't load, but the SSL symbols are now proper. This creates weird bug reports for nodejs extension developers, such as https://github.com/grpc/grpc-node/issues/341 Another example is uws. Trying to use uws in ubuntu's nodejs will result in the same sort of failures. Which means there are at least two packages available out there that are affected by this issue. I don't think this is easily solvable, and all of my suggestions for fixing it have severe cons. Ubuntu won't want to downgrade their system's OpenSSL for this. Maybe there's a way to get another openssl package for 1.0.2, and have the nodejs runtime for Ubuntu depend on it. Another possible solution would be to radically upgrade nodejs to 10, so that the ABI of OpenSSL will then match properly. But this may be viewed as a too radical upgrade. One sort of mitigation option would be to get node-pre-gyp and prebuild to recognize that it's running with this version of the nodejs runtime, so that it can recognize and take actions, such as downloading an ubuntu-specific version of the prebuilt extension, or recompiling from sources. This obviously would help mitigating the issue for a good portion of existing packages that are using node-pre- gyp and prebuild, but for packages that are doing their own thing such as uws, this solution wouldn't work properly.
