update to julia-0.7/1.0

[alyst]

This PR requires JuliaData/RData.jl#44 to be merged and minimal RData version to be bumped.

[andreasnoack]

@alyst Could you please push a version with an updated RData requirement?

[alyst]

@andreasnoack Currently testing it locally, then will update the changes. BTW, do you know the fate of johnmileswhite/MNIST.jl? It wasn't touched for years, PRs ignored. It doesn't have much functionality, but it contains a medium-sized MNIST dataset that is used for testing/benchmarking TSne.jl. Copying these data to TSne.jl would make it too heavy. Maybe there's another Julia datasets package that already contains it? Or, if somebody can merge the PR, I can update MNIST.jl to 0.7/1.0. Or, the data could be moved to RDatasets (but we might not want to feed it into a mammoth).

[andreasnoack]

MNIST is in https://github.com/JuliaML/MLDatasets.jl which is actively maintained so I'd recommend using that version

[alyst]

Ah, good to now. Will switch to it. Maybe somebody could update MNIST.jl/README.md to redirect people to MLDatasets.jl? So far it's in the registry, so people will keep discovering it.

[alyst]

It seems there's a considerable CSV-related memory leak. When testing locally, my 24Gb RAM is not enough. When I skip CSV datasets, everything is much faster and memory usage is normal.

[alyst]

@andreasnoack FYI johnmyleswhite/MNIST.jl#30

[andreasnoack]

It seems there's a considerable CSV-related memory leak

Could you elaborate?

[alyst]

Could you elaborate?

While previously (v0.6) RDatasets tests were also running pretty slow, I don't recall I had memory issues.
With this version, when testing locally, dataset.jl test script didn't finish and the memory usage was above 24GB (I suspect julia test process was killed, although there was no crash report).
I don't think the RDatasets.jl is responsible for the leak. When I skip .csv datasets (i.e. testing .rda data only), everything is running fast.
I don't know what is the cause. There's JuliaData/CSV.jl#236, which is worth investigating anyway, because allocation and CPU overhead for 2-row file is suspiciously high. However, I've tried reading that file 10000 times and I didn't observe increased memory usage. It might be something WeakRefStrings/InternedStrings related: unique strings from all datasets are cached (esp. during column type autodetection), but never freed.

I suspect Julia 1.0 Travis build failed because of the same issue (the other builds suffered from network problems). The stacktrace is strange:

I reported about the CSV issue with a 2-row file, and I just updated about it there.

Talking about csv memory leak, I have been battling for quite some time to find out the issue. Recently I inquired at the forum here. I can't pinpoint about the leak, but it seems very possibly related to csv related utilities.

[alyst]

This is how running ]test RDatasets looks like on my laptop until I kill it.

[andreasnoack]

@quinnj Do you have any idea what is happening here?

...

and I get something similar when taking a sample during execution. It seems to be consistently happening in the mexico dataset from the Zelig group but it doesn't happen if I load the datasets one-by-one outside of a loop. However, it seems to be sufficient to just run this loop https://github.com/johnmyleswhite/RDatasets.jl/blob/482317f99aa76b4cbc1f2df4ee0068d25c032ae1/test/dataset.jl#L8-L20

[JeffBezanson]

T = Tuple{NTuple{33,Union{Missing, Int64}}}

T <: Tuple{T} where T<:(Tuple{Vararg{E, N} where N} where E)
# fine

T <: (Tuple{T} where T<:Tuple{Vararg{E, N} where N}) where E
# takes "a while" :)

I'll work on it. I think the problem is that we have to wait until we leave the UnionAll for E to see that its constraints can't be met, when we could potentially see that earlier.

[andreasnoack]

I suspect that this might be the same as reported in JuliaData/CSV.jl#236

[randyzwitch]

This memory leak aside, is there any reason else not to merge this PR? It doesn't appear the memory leak is related to the PR itself, and the memory leak can be explored elsewhere.

[alyst]

@randyzwitch Thanks for the reminder! Now it passes on Julia nightly, so I think it's safe to merge (cc @andreasnoack)

[randyzwitch]

@alyst I'm not sure passing only on nightly is a reasonable jump for this package, since 0.7 and 1.0 is the original goal

[alyst]

@randyzwitch CI doesn't pass on 0.7 and 1.0 because of (at least) JuliaLang/julia#28677, RDatasets (and CSV) itself is fine.
I think it's fine to release it, because IRL you would not try to load all CSV datasets at once, loading individual datasets should be ok.
Also, I would have postpone it, had there been already a version of RDatasets that doesn't trigger Julia bug, but ATM there are no stable versions that run on v0.7/v1.0.
Alternatively, we can wait until 1.0.1.

[randyzwitch]

Thanks for the explanation @alyst. Can you add this note to the README, so that users coming in can understand that the package is expected to be working, just that it depends on a fix in master? Then I'll merge it in.

[alyst]

@randyzwitch Good idea, I've added a note to README.

[randyzwitch]

Merged

[alyst]

@randyzwitch Could you please also tag a new minor release?

[andreasnoack]

It looks like Attobot isn't enabled so I've opened JuliaLang/METADATA.jl#17366
