Failed to connect to data.iana.org port 443: Timed out

[jaakkor2]

I am on Windows 10 and Julia v1.4.1.

During updating I saw this (and I think I have seen it before)

  [f269a46b] ↑ TimeZones v1.1.0 ⇒ v1.1.1

Then trying again after awhile

@v1.4) pkg> build TimeZones
   Building TimeZones → `C:\Users\jruohio\.julia\packages\TimeZones\X323b\deps\build.log`

it succeeds.

Maybe the curl timeout could be a bit longer. Some discussion here https://unix.stackexchange.com/questions/94604/does-curl-have-a-timeout/94612. To be checked what is the default timeout now.

[omus]

Thanks for the issue. TimeZones uses Julia's Base.download which uses the default timeout for curl and provides no way of modifying it. How quickly does the download fail for you?

Something interesting I noticed in your output is that you upgraded from TimeZones 1.1.0 to 1.1.1 where no tzdata change took place. Usually when that is the case TimeZones avoids downloading the tzdata archive again.

[jaakkor2]

I tried again with tzdata2019c.tar.gz, first trial failed, five next succeeded.

Timeout in about 20 s. Trying with another dataset looks like this.
Not clear to me is the problem at ISP or at iana.org. Maybe TimeZones.jl could try two or three times before failing?

I can introduce a retry for download failures

[omus]

If you want to try out the retry feature you can do so with:

using Pkg
Pkg.add(PackageSpec(name="TimeZones", rev="cv/download-retry"))

[jaakkor2]

I tried to add the download-retry branch on an empty depot path. It went smooth.

I cleaned everything, and tried again, and this was the result. It timed out three times, and ultimately failed.

[omus]

Very strange. Do you have issues connecting to https://data.iana.org/time-zones/releases/ in a browser? I've found the IANA server to be very reliable.

What IP address do you get for the IANA server?

julia> using Sockets

julia> getaddrinfo("data.iana.org")
ip"72.21.81.189"

[jaakkor2]

The IP address is the same

julia> getaddrinfo("data.iana.org")
ip"72.21.81.189"

I tried to download five different datasets using Firefox, all of them were successful.

Using Julia to download those seem to be more variable, sometimes success, sometimes timeout. This is weird: I had two Julia terminals open

• Terminal A: I could download("https://data.iana.org/time-zones/releases/tzdata2015a.tar.gz"), but download("https://data.iana.org/time-zones/releases/tzdata2014a.tar.gz") timed out.
• Terminal B: I could download("https://data.iana.org/time-zones/releases/tzdata2014a.tar.gz"), but download("https://data.iana.org/time-zones/releases/tzdata2015a.tar.gz") timed out.

[omus]

Maybe the issue is with curl here? You could try using the same command but increase verbosity. From the cmd.exe prompt:

'C:\WINDOWS\System32\curl.exe' curl -s -S -g -L -v -o demo.tar.gz https://data.iana.org/time-zones/releases/tzdata2019c.tar.gz

Or in Julia:

julia> run(`'C:\WINDOWS\System32\curl.exe' curl -s -S -g -L -v -o demo.tar.gz https://data.iana.org/time-zones/releases/tzdata2019c.tar.gz`)

[jaakkor2]

I tried twice, first succeeded, second failed.

At this point I the issue I think the issue may have to do with Base.download. After inspecting the Base.download code there is a Windows only alternative Base.download_powershell which you may want to try out to see if it works any better (e.g. Base.download_powershell("https://data.iana.org/time-zones/releases/tzdata2019c.tar.gz", "demo.tar.gz"))

I would open a issue against Julia itself (https://github.com/JuliaLang/julia/issues) once you confirm that this issue occurs with other URLs. I suspect it will as the IANA server appears to me to be very reliable.

This seems to be very robust in PowerShell

Invoke-WebRequest -Uri https://data.iana.org/time-zones/releases/tzdata2019c.tar.gz -OutFile tzdata2019c.tar.gz

In fact, call to curl is actually a call to Invoke-WebRequest in PowerShell.

In cmd.exe, this sometimes fails, sometimes succeeds

>curl --silent --show-error --globoff --location --fail "https://data.iana.org/time-zones/releases/tzdat
a2019c.tar.gz" --output tzdata2019c.tar.gz

but I did not yet see downloading Julia fail, tried >10 times

>curl --silent --show-error --globoff --location --fail "https://julialang-s3.julialang.org/bin/winnt/x6
4/1.4/julia-1.4.1-win64.exe" --output "julia-1.4.1-win64.exe"

Curl version is

>curl --version
curl 7.55.1 (Windows) libcurl/7.55.1 WinSSL
Release-Date: [unreleased]
Protocols: dict file ftp ftps http https imap imaps pop3 pop3s smtp smtps telnet tftp
Features: AsynchDNS IPv6 Largefile SSPI Kerberos SPNEGO NTLM SSL
