Problem with curl.exe (Windows) and package installation

oheil · October 9, 2019, 3:36pm

On Windows Base.download() behaves like:

Julia 1.1:
powershell
can be altered by overwriting Base.download()
Julia 1.2:
Windows 10: C:\Windows\system32\curl.exe
Windows <10: powershell
can be altered by overwriting Base.download() or Base.find_curl()
Julia 1.3:
Windows 10: C:\Windows\system32\curl.exe
Windows <10: powershell
can be altered by overwriting Base.download() or Base.find_curl()

Windows<10 depends on the point from when curl.exe exists in C:\Windows\system32. This is not the case for Windows 7 (can’t check for Windows 8, but doesn’t matter so much).

The switch to curl.exe maybe motivated by the following comment in the code:
# PowerShell v3 or later is required for Tls12

libcurl is not part of plain Julia on Windows.

Is it part of Julia on other platforms? All I could find is that it was proposed in

Future of Base.download

I/O

We currently export a `download` function from Base for downloading files. It ha…s some issues: - it shells out to an external program, currently `wget`, `curl` or `fetch` on unix, or a PowerShell command on Windows. Since these utilities are not bundled with Julia, they can cause problems if they don't exist on the system or are otherwise misconfigured (#26459, #22783, #17889) - it is fairly basic feature wise: e.g. it doesn't support: * "silent" mode for hiding output (#15930) * capturing of stdout/stderr * consistent progress bar * logging * useful error codes/messages * restarting terminated downloads - the whole GitHub TLS mess As a result, several packages implement their own functionality, notably BinDeps.jl, BinaryProvider.jl, and Pkg3.jl (pending https://github.com/JuliaLang/Pkg3.jl/pull/280). In fact, it doesn't appear to be currently used anywhere in Base or stdlib (it is mentioned in a couple of comments in the REPL code). Some options: - Move it to a stdlib package to make it easier to update, add features etc (at least it will once we have versioned stdlib packages). - Add the functionality to HTTP.jl, and move that to stdlib. This would have the advantage of getting rid of the mish-mash of shell code we currently use (suggested in https://github.com/JuliaLang/julia/pull/26559#issuecomment-378412637) - Get rid of it altogether. cc: @staticfloat @tkelman @samoconnor

It looks like HTTP.download is the future. Doesn’t look like libcurl or curl is bundled on any other OS.
Anyways, the basic issue seems to be on the monitor and more or less solved in future julia releases.

Iagoba_Apellaniz · December 16, 2019, 9:06am

I’m not able to solve this.

I downloaded a new version for cURL (but I cannot even change the name of system32/curl.exe, since the computer is administrated by the university and I have not the necessary priviledges)
I upgraded Julia to 1.3.0
I changed the find_curl() to nothing
etc.

I write because I’m running out of ideas.

oheil · December 16, 2019, 9:18am

Change find_curl() to return the path to your new downloaded curl binary, e.g.:

julia> Base.find_curl() = "C:\\path\\to\\downloaded\\curl.exe"

Iagoba_Apellaniz · December 16, 2019, 9:30am

Thanks, but it doesn’t work. I also changed the PATH variable so now is pointing to the newest curl.exe.

oheil · December 16, 2019, 9:36am

Do you have some errors to show?

The PATH variable is not working in this case because:

function find_curl()
    if Sys.isapple() && Sys.isexecutable("/usr/bin/curl")
        "/usr/bin/curl"
    elseif Sys.iswindows() && Sys.isexecutable(joinpath(get(ENV, "SYSTEMROOT", "C:\\Windows"), "System32\\curl.exe"))
        joinpath(get(ENV, "SYSTEMROOT", "C:\\Windows"), "System32\\curl.exe")
    elseif !Sys.iswindows() && Sys.which("curl") !== nothing
        "curl"
    else
        nothing
    end
end

It returns

joinpath(get(ENV, "SYSTEMROOT", "C:\\Windows"), "System32\\curl.exe")

The errors are related with cURL

The only idea I didn’t try is to change find_curl() in the source code and compile Julia. But I want to find an easier (even if it is temporary) solution.

Thank you. If some more details are needed I’ll try to collect them. I really appreciate your help.

oheil · December 16, 2019, 10:02am

I think its best for now to edit the source.
It is in
c:\Users\YOUR_NAME\AppData\Local\Julia-1.3.0\share\julia\base\download.jl

I don’t know why redefining Base.find_curl() is ignored and don’t have the time now to find out.

Iagoba_Apellaniz · December 16, 2019, 10:31am

Thanks!! I edited the code. How should I rebuild Base now? Anyone has any idea?

I downloaded the julia v1.3 binary and not the whole source code.

Sijun · December 16, 2019, 10:33am

create a file called “_curlrc” that contains “insecure” (wihout quote) and place it in your %APPDATA% (echo %APPDATA%). For windows, curlrc file should begin with underscore.

https://curl.haxx.se/docs/manual.html

Iagoba_Apellaniz · December 16, 2019, 10:38am

Thank you very much! It did work! … trying to solve this for ages

Sijun · December 16, 2019, 10:40am

glad to be of help

giordano · December 16, 2019, 11:58am

Can you please summarise the steps you take to make download work?

Iagoba_Apellaniz · December 16, 2019, 12:25pm

In Wondows 10 (I don’t know for other Windows versions).

Open a command prompt, and type echo %APPDATA% to get the personal app data folder.
Create an empty file called _curlrc in the app data folder.
Write insecure on that file and save.
Relaunch julia and build all affected packages with ] up or similar.

Hope this is detailed enough.

oheil · December 16, 2019, 12:46pm

Great to have a work around finally! But be aware that this setting should not stay permanently.

kkmann · January 13, 2020, 11:45am

@Iagoba_Apellaniz just made me aware of this thread - I might have similar issues on a mac, cf. Curl certificate issue with Pkg3 on Mac.

bwang12 · January 20, 2020, 2:19am

Thanks for the share but unfortunately it did not work for me.
I deleted all compiled cache from .julia/Compiled and rebuilt everything.
The error remain the same:
