it fails to download some of the requirements:

cabal: Failed to download
http://hackage.haskell.org/packages/archive/00-index.tar.gz : ErrorMisc "Error
HTTP code: 400"

Downloading the file manually works ok.

Sorry if this is not correct place to report the issue, if thats the case, please can you let me know where should I report it instead?

Thanks!

Most likely some configuration problem on your end or a bug in the HTTP library.

Try compiling and running this test program. If it fails, then this is not a Cabal issue.

Related: #2035.

[svalaskevicius]

yes, it does fail too:

Test2035: Error HTTP code: 400

could you maybe help in redirecting the report to the interested parties? (should I raise an issue in https://github.com/haskell/HTTP ? )

Thanks,

the system call trace:

also, the same in nc works ok:

printf "GET /packages/archive/00-index.tar.gz HTTP/1.1\r\nHost: hackage.haskell.org\r\nUser-Agent: cabal-install/1.18.0.5\r\n\r\n" | nc hackage.haskell.org 80
HTTP/1.1 301 Moved Permanently
...

could it be because of the different syscalls to send the request (in several parts)?

@svalaskevicius

(should I raise an issue in https://github.com/haskell/HTTP ? )

Yes, please do. Closing, since this is not a Cabal bug.

[svalaskevicius]

interestingly enough, it started working a few minutes/hours ago.. maybe there was something wrong with the hackage server?

thanks for your help!

[ravshanof]

any updates on that?
