Native Windows curl doesn't create paths with forward slashes #1007

On a similar note, it appears that the MSYS2 version of |

So this: https://github.com/curl/curl/blob/master/lib/curl_setup.h#L448 should have some #ifdef logic to detect mingw and then use a forward slash? |

Ideally the code should recognise both |

I don't think that'd be the fix I want, since if you require paths to be separated by forward slashes with MinGW-w64, then paths like I'd want at least the MinGW-w64 version of FWIW, this command: seems to work if the |
|
The current command line tool logic for this uses only one slash: https://github.com/curl/curl/blob/master/src/tool_dirhie.c#L117 I suppose that function should be fixed to work with backslashes and forward slashes (on windows)? Or do we have this problem elsewhere as well? |
That sounds good to me! |
|
Similar issue may be present on MS-DOS and OS/2. Though I don't have information on how expected it is from tools to transparently accept forward slashes on these systems — probably not very. |
|
@vszakats I don't remember DOS and OS/2 using the forward slash very much for that, but the code should probably be written with a nice #ifdef in there somehow anyway and then the DOS and OS/2 aware people can later switch on that logic if deemed applicable. I don't think we have a very large user base on those operating systems (but yes it exists). @RyanGlScott you feel like taking a stab at writing an improved version of that function? |

@bagder Agreed! |

Thanks, @badger! When I get a chance I'll try this patch out and see if it fixes the issues I've been having. |
|
(and just for the record, I'm @bagder, which the g and d switched!) |
|
That patch works beautifully! |

thanks! |

I did this
I used the native Windows version of
curl(in MSYS2 terms, this ismingw-w64-x86_64-curl) to download a file to a path containing forward slashes, but it failed unexpectedly:I expected the following
I expected it to behave like
curldoes on Linux, or how the MSYS2-built version ofcurlbehaves (i.e., howcurlbehaves in a POSIX emulation layer):A workaround is to convert all the forward slashes (
/) in that path to backslashes (\\):curl/libcurl version
I reproduced this with versions 7.50.1 and 7.50.2.
operating system
Windows 10 (64-bit)
I installed the native Windows version and the MSYS2 version of
curlusingpacman -S mingw-w64-x86_64-curlandpacman -S curl, respectively, but @vszakats reports experiencing the same issue using the Windows version ofcurl-7.50.2available for download from thecurlwebsite.The text was updated successfully, but these errors were encountered:
