Native module compilation with io.js 2.x.x #1620
Description
Activity
See also / previously: #456
Don't comment here with packages please. Just link to
https://github.com/iojs/io.js/issues/1620when you create the issue on the package's github tracker. :)@Fishrock123 good idea.
Just removed original comment and added reference from appropriate pull requests/issues I have openened for this.
Here's a somewhat improved search query.
I am not very used to querying CouchDB but this request seems to give all npm modules that have
nanas dependency: https://skimdb.npmjs.com/registry/_design/app/_view/dependentVersions?startkey=[%22nan%22]&endkey=[%22nan!%22]&reduce=falseThis is going to hurt.
We need to find a better way to handle this. As I see it we have two routes:
- Automate the updating of all these modules in npm/github.
- Take
nanin to core.
Cool, that seems right. It would be awesome if someone were to put together a version-bump bot for minor versions of NAN (unless the package depends on ^1.0, 1.x or *, as those already resolve to latest version in the major). Unfortunately io.js 3.0 will require NAN 2.0, which is going to require rather substantial rewriting. The conversion could still be automated or semi-automated.
Take
nanin to core.👍
This would be awesome and bring lot of stability to native bindings.
$ wget -qO- 'https://skimdb.npmjs.com/registry/_design/app/_view/dependentVersions?startkey=%5B"nan"%5D&endkey=%5B"nan!"%5D&reduce=false' | tail -n +2 | head -n -1 | egrep -v '1\.8|\^1|1\.x|\*'

I can think of many reasons why that will end up introducing more breakage down the road than it fixes.
Someone (and I'm not volunteering) should come up with a detailed proposal how to implement that and be prepared for some serious hole shooting.
another option .. which I've resisted and actively recommended against, is getting packages to use
^in their nan dependency definition, those that use this range should work just fine because we're still in1.x. I'm hessitant to do this because of my deep distaste and distrust of such a liberal range but it would deal with this particular problemThe whole point of nan is more liberal support of node/io.js versions, so it makes sense to me that the dependency would have a more liberal range.

Autodetection defaults to 2010, yes. You need to explicitly specify msvs_version=2013 to gyp.

#1620 (comment)I figured it would not create too much problems by releasing a minor.
I would agree with you about that. semver is no panacea, and that might have been a good judgement call.
Except it wasn't, because nan apparently recommends pinning deps to MINORS instead of allowing them to float within a MAJOR, everyone following nan's advice had to update their package.
If you have to update a package, who cares if you update from

Yes, you may be right. The recommendation of pinning to minors originated before the ^-notation had become available, and since then we have gradually adopted a stricter adherence to semver.
We try to keep backwards compatibility across versions, but sometimes mistakes happen. There have been around two or three occasions where in the last year where a new minor of NAN has unintentionally broken some configurations. This typically results in bug reports within an hour of release. It is usually fixed within a day or so, but builds breaking because of this can be very confusing to unexpecting users.
Most packages depend on NAN indirectly through the dependency chain, over 40 % of all the packages in npm, so any bugs affect a lot of packages.
So, while the intention is that users should be able to pin to majors of NAN, there may be temporary issues with large impact across the ecosystem when doing this.
Sometimes we release minors just to add more APIs or rewrite the internals of existing ones to fix bugs or improve performance. These are often not strictly necessary for functionality for every addon. These can be avoided by pinning to minors.

I would agree with you about that. semver is no panacea, and that might
have been a good judgement call.Except it wasn't, because nan apparently recommends pinning deps to
MINORS instead of allowing them to float within a MAJOR, everyone
following nan's advice had to update their package.If you have to update a package, who cares if you update from

Mistakes happen, but if nan releases a breaking change in a minor by accident, as you say, there will be bug reports pretty quickly, and nan can make things right with a single publish, and everything will work again. No big deal, nan is pretty diligent, as you say, they/you fix these things quite quickly.
When an update to io.js requires a minor update to nan, there are more than temporary issues, as volunteers need to work through the entire set of minor-pinned packages. As you say, binary addons tend to be buried deep, so its even hard for people to fix themselves without forking all the intermediary deps. Its a bit frustrating that the issues can't be solved quickly by nan, we have to wait for the ecosystem to catch up.
Anyhow, its a bit late. My random sampling of the merges that mention this PR found that they are all minor pinned.
But the next time nan bumps a minor to get io.js compatibility again, as is sure to happen, please consider asking people up to use the
^, so nan itself can fix the addon ecosystem in the future without this kind of churn. At least until V8 changes something so important that nan can't paper over it with its current macros, and nan users really will have to rewrite some of their bindings. That's out of all of our control, though.- I will continue to recommend ~ over ^ in pretty much all cases. Minor bumps of any library tend to have more impact on the internals in ways that can expose breakage of edge cases--or even common cases that aren't being properly accounted for in tests. It should be the library author's responsibility to keep a close eye on shifting dependency versions and testing if stuff still works. If that means accepting a lot of pull requests then so be it. One example of this kind of breakage with NAN was the rewrite of NanNew which replaced most of the internals but kept a consistent API, or so we thought, until we got a slew of bug reports from people who's deploys were suddenly broken because of transitive dependency drift where NAN was automatically upgraded. This is only one case but it's a typical story in rapidly developing projects, it happens over and over. As a library author I take responsibility for the current state of my code and how it's supposed to work and under what conditions. ^ assumes that authors of my dependencies have complete knowledge of how their API is being used and a complete test suite that covers all of my exact uses. This is garbage of course and I opt to limit my risk. ~ is my chosen level of risk, I know some who opt for exact versions for similar reasons and I understand this position. Semver cannot account for human imperfections and we shouldn't pretend it's an accurate representation of what happens in the software development process. So, I will continue to maintain that ^ represents a very high level of risk for software stability and will continue to advocate against its use.
👍 @rvagg
I will admit that I've taken to bumping major versions not just when making a "breaking change", but also when I feel that something that has changed under the hood and represents enough risk that it needs to be an intentional change by a package consumer.
It does feel a bit strange, but with the
--savesyntax using the^specifier by default I don't think I have much other choice. I think while the original intent of moving to the hat syntax for--saveoperations was to highlight the importance of using the major version component of our packages, it has had a side effect that does need to be addressed.That will likely not happen. io.js 3.0 will probably be released within a week or two. NAN 2.0 will be released soon after that. There is, however, a 'next' branch available that builds with io.js next. It will become 2.0, but is not finalized or frozen yet. It aims at working with V8 4.5, which is the current development branch, so that there won't be unnecesary, avoidable, breakage.
All 500+ packages will need rewriting and updating. This will not happen overnight. I'm considering writing a simple migration script, like 2to3.py, which should take care of some changes automatically. But, it will take some time to write and will not cover everything. If someone were to put this together, I'd gladly accept a PR.

However, I still strongly suggest that package authors should be given
opportunity to migrate to newer NAN well before ABI breaking core
changes are publicly released.In this case I hope to see NAN
2.x.xwell before core hits3.x.x.

#1620 (comment)If npm packages were integrated with Travis CI or something similar, we'd have more accurate information about the build status of packages, which might be useful in general, especially for in this situation.
@RnbWd Excellent idea.
Many packages are already individually testing with Travis CI pulling from GitHub, but more general automated testing done straight from npm repository against available Node/io.js versions would be an awesome service. It could easily show compatibility statistics against any core version. I think running simple npm install (and npm test only if enabled by package author) would be enough.
I think someone is already working on this ;) If not, then someone should.
Add this to your
.npmrcsave-exact=trueNow every
--savewill use exact versions. I think there is an equivalent for~but I don't remember it.@defunctzombie definitely agree! I use that setting as well. You can use
npm config ls -lto show all defaults, so changing to~would be changingsave-prefix = "~", althoughsave-exactprobably overridessave-prefix. cmdline:npm set save-prefix '~' or npm set save-exact trueedit: is there any benefit using
save-prefix="~"?@defunctzombie @RnbWd thanks - sounds like a plan :)
3.0.0 has been released, so I'll close this one for now. :)
I'm opening this issue to track modules needing updates to
nandependency (or something else) for io.js2.0.0compatibility.
