Hello all, long time git user, I encountered an issue when using a git dependency in python poetry, and I got down all the way to the way the git client & github.com are communicating, which is interesting and I'm wondering if this is normal behavior, it definitely looks unintuitive to me.
Basically github.com, when specifying an inexistent repo (e.g., due to a typo in the project name) serves a HTTP 401 to the git client, while it serves a HTTP 404 to normal clients. To replicate, try `git clone https://github.com/rienafairefr/flask_pika` The repo doesn't exist (it should be flask-pika with a dash not an underscore...), and yet the git client (with v2.25.1 at least) wants our username for github.com with GIT_CURL_VERBOSE: ``` Cloning into 'flask_pika'... * Couldn't find host github.com in the .netrc file; using defaults * Trying 140.82.121.3:443... * TCP_NODELAY set * Connected to github.com (140.82.121.3) port 443 (#0) * found 391 certificates in /etc/ssl/certs * ALPN, offering h2 * ALPN, offering http/1.1 * SSL connection using TLS1.3 / ECDHE_RSA_AES_128_GCM_SHA256 * server certificate verification OK * server certificate status verification SKIPPED * common name: github.com (matched) * server certificate expiration date OK * server certificate activation date OK * certificate public key: RSA * certificate version: #3 * subject: C=US,ST=California,L=San Francisco,O=GitHub\, Inc.,CN=github.com * start date: Tue, 05 May 2020 00:00:00 GMT * expire date: Tue, 10 May 2022 12:00:00 GMT * issuer: C=US,O=DigiCert Inc,OU=www.digicert.com,CN=DigiCert SHA2 High Assurance Server CA * ALPN, server accepted to use http/1.1 > GET /rienafairefr/flask_pika/info/refs?service=git-upload-pack HTTP/1.1 Host: github.com User-Agent: git/2.25.1 Accept: */* Accept-Encoding: deflate, gzip, br Accept-Language: en-US, *;q=0.9 Pragma: no-cache * Mark bundle as not supporting multiuse < HTTP/1.1 401 Authorization Required < Server: GitHub Babel 2.0 < Content-Type: text/plain < Content-Length: 21 < WWW-Authenticate: Basic realm="GitHub" < X-Frame-Options: DENY < X-GitHub-Request-Id: C970:DCEC:6424D55:90F0755:5F895E20 < * Connection #0 to host github.com left intact Username for 'https://github.com': ``` We got a http 401, whereas a regular client (here, httpie) on the exact same URL gets a 404: ``` GET /rienafairefr/flask_pika/info/refs?service=git-upload-pack HTTP/1.1 User-Agent: HTTPie/1.0.3 Accept-Encoding: gzip, deflate Accept: */* Connection: keep-alive Host: github.com HTTP/1.1 404 Not Found date: Fri, 16 Oct 2020 08:48:11 GMT content-type: text/plain; charset=utf-8 server: GitHub.com ``` The fix is easy (fix the typo !), but there is something very unintuitive about a 401 returned on an inexistent resource, and I don't know where the error is (in the git protocol, or the server behind github.com git service, "babel 2.0"), and I'd love to get the perspective of git experts.
