In + addition to the syntax understood by curl, it is possible to specify a + proxy string with a user name but no password, in which case git will + attempt to acquire one in the same way it does for other credentials. See + linkgit:gitcredentials[7] for more information. The syntax thus is + '[protocol://][user[:password]@]proxyhost[:port]'. This can be overridden + on a per-remote basis; see remote..proxy + +http.proxyAuthMethod:: + Set the method with which to authenticate against the HTTP proxy. This + only takes effect if the configured proxy string contains a user name part + (i.e. is of the form 'user@host' or 'user@host:port'). This can be + overridden on a per-remote basis; see `remote..proxyAuthMethod`. + Both can be overridden by the `GIT_HTTP_PROXY_AUTHMETHOD` environment + variable. Possible values are: ++ +-- +* `anyauth` - Automatically pick a suitable authentication method. It is + assumed that the proxy answers an unauthenticated request with a 407 + status code and one or more Proxy-authenticate headers with supported + authentication methods. This is the default. +* `basic` - HTTP Basic authentication +* `digest` - HTTP Digest authentication; this prevents the password from being + transmitted to the proxy in clear text +* `negotiate` - GSS-Negotiate authentication (compare the --negotiate option + of `curl(1)`) +* `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`) +-- + +http.emptyAuth:: + Attempt authentication without seeking a username or password. This + can be used to attempt GSS-Negotiate authentication without specifying + a username in the URL, as libcurl normally requires a username for + authentication. + +http.delegation:: + Control GSSAPI credential delegation. The delegation is disabled + by default in libcurl since version 7.21.7. Set parameter to tell + the server what it is allowed to delegate when it comes to user + credentials. Used with GSS/kerberos. Possible values are: ++ +-- +* `none` - Don't allow any delegation. +* `policy` - Delegates if and only if the OK-AS-DELEGATE flag is set in the + Kerberos service ticket, which is a matter of realm policy. +* `always` - Unconditionally allow the server to delegate. +-- + + +http.extraHeader:: + Pass an additional HTTP header when communicating with a server. If + more than one such entry exists, all of them are added as extra + headers. To allow overriding the settings inherited from the system + config, an empty value will reset the extra headers to the empty list. + +http.cookieFile:: + The pathname of a file containing previously stored cookie lines, + which should be used + in the Git http session, if they match the server. The file format + of the file to read cookies from should be plain HTTP headers or + the Netscape/Mozilla cookie file format (see `curl(1)`). + NOTE that the file specified with http.cookieFile is used only as + input unless http.saveCookies is set. + +http.saveCookies:: + If set, store cookies received during requests to the file specified by + http.cookieFile. Has no effect if http.cookieFile is unset. + +http.version:: + Use the specified HTTP protocol version when communicating with a server. + If you want to force the default. The available and default version depend + on libcurl. Actually the possible values of + this option are: + + - HTTP/2 + - HTTP/1.1 + +http.sslVersion:: + The SSL version to use when negotiating an SSL connection, if you + want to force the default. The available and default version + depend on whether libcurl was built against NSS or OpenSSL and the + particular configuration of the crypto library in use. Internally + this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl + documentation for more details on the format of this option and + for the ssl version supported. Actually the possible values of + this option are: + + - sslv2 + - sslv3 + - tlsv1 + - tlsv1.0 + - tlsv1.1 + - tlsv1.2 + - tlsv1.3 + ++ +Can be overridden by the `GIT_SSL_VERSION` environment variable. +To force git to use libcurl's default ssl version and ignore any +explicit http.sslversion option, set `GIT_SSL_VERSION` to the +empty string. + +http.sslCipherList:: + A list of SSL ciphers to use when negotiating an SSL connection. + The available ciphers depend on whether libcurl was built against + NSS or OpenSSL and the particular configuration of the crypto + library in use. Internally this sets the 'CURLOPT_SSL_CIPHER_LIST' + option; see the libcurl documentation for more details on the format + of this list. ++ +Can be overridden by the `GIT_SSL_CIPHER_LIST` environment variable. +To force git to use libcurl's default cipher list and ignore any +explicit http.sslCipherList option, set `GIT_SSL_CIPHER_LIST` to the +empty string. + +http.sslVerify:: + Whether to verify the SSL certificate when fetching or pushing + over HTTPS. Defaults to true. Can be overridden by the + `GIT_SSL_NO_VERIFY` environment variable. + +http.sslCert:: + File containing the SSL certificate when fetching or pushing + over HTTPS. Can be overridden by the `GIT_SSL_CERT` environment + variable. + +http.sslKey:: + File containing the SSL private key when fetching or pushing + over HTTPS. Can be overridden by the `GIT_SSL_KEY` environment + variable. + +http.sslCertPasswordProtected:: + Enable Git's password prompt for the SSL certificate. Otherwise + OpenSSL will prompt the user, possibly many times, if the + certificate or private key is encrypted. Can be overridden by the + `GIT_SSL_CERT_PASSWORD_PROTECTED` environment variable. + +http.sslCAInfo:: + File containing the certificates to verify the peer with when + fetching or pushing over HTTPS. Can be overridden by the + `GIT_SSL_CAINFO` environment variable. + +http.sslCAPath:: + Path containing files with the CA certificates to verify the peer + with when fetching or pushing over HTTPS. Can be overridden + by the `GIT_SSL_CAPATH` environment variable. + +http.sslBackend:: + Name of the SSL backend to use (e.g. "openssl" or "schannel"). + This option is ignored if cURL lacks support for choosing the SSL + backend at runtime. + +http.schannelCheckRevoke:: + Used to enforce or disable certificate revocation checks in cURL + when http.sslBackend is set to "schannel". Defaults to `true` if + unset. Only necessary to disable this if Git consistently errors + and the message is about checking the revocation status of a + certificate. This option is ignored if cURL lacks support for + setting the relevant SSL option at runtime. + +http.schannelUseSSLCAInfo:: + As of cURL v7.60.0, the Secure Channel backend can use the + certificate bundle provided via `http.sslCAInfo`, but that would + override the Windows Certificate Store. Since this is not desirable + by default, Git will tell cURL not to use that bundle by default + when the `schannel` backend was configured via `http.sslBackend`, + unless `http.schannelUseSSLCAInfo` overrides this behavior. + +http.pinnedpubkey:: + Public key of the https service. It may either be the filename of + a PEM or DER encoded public key file or a string starting with + 'sha256//' followed by the base64 encoded sha256 hash of the + public key. See also libcurl 'CURLOPT_PINNEDPUBLICKEY'. git will + exit with an error if this option is set but not supported by + cURL. + +http.sslTry:: + Attempt to use AUTH SSL/TLS and encrypted data transfers + when connecting via regular FTP protocol. This might be needed + if the FTP server requires it for security reasons or you wish + to connect securely whenever remote FTP server supports it. + Default is false since it might trigger certificate verification + errors on misconfigured servers. + +http.maxRequests:: + How many HTTP requests to launch in parallel. Can be overridden + by the `GIT_HTTP_MAX_REQUESTS` environment variable. Default is 5. + +http.minSessions:: + The number of curl sessions (counted across slots) to be kept across + requests. They will not be ended with curl_easy_cleanup() until + http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this + value will be capped at 1. Defaults to 1. + +http.postBuffer:: + Maximum size in bytes of the buffer used by smart HTTP + transports when POSTing data to the remote system. + For requests larger than this buffer size, HTTP/1.1 and + Transfer-Encoding: chunked is used to avoid creating a + massive pack file locally. Default is 1 MiB, which is + sufficient for most requests. + +http.lowSpeedLimit, http.lowSpeedTime:: + If the HTTP transfer speed is less than 'http.lowSpeedLimit' + for longer than 'http.lowSpeedTime' seconds, the transfer is aborted. + Can be overridden by the `GIT_HTTP_LOW_SPEED_LIMIT` and + `GIT_HTTP_LOW_SPEED_TIME` environment variables. + +http.noEPSV:: + A boolean which disables using of EPSV ftp command by curl. + This can helpful with some "poor" ftp servers which don't + support EPSV mode. Can be overridden by the `GIT_CURL_FTP_NO_EPSV` + environment variable. Default is false (curl will use EPSV). + +http.userAgent:: + The HTTP USER_AGENT string presented to an HTTP server. The default + value represents the version of the client Git such as git/1.7.1. + This option allows you to override this value to a more common value + such as Mozilla/4.0. This may be necessary, for instance, if + connecting through a firewall that restricts HTTP connections to a set + of common USER_AGENT strings (but not including those like git/1.7.1). + Can be overridden by the `GIT_HTTP_USER_AGENT` environment variable. + +http.followRedirects:: + Whether git should follow HTTP redirects. If set to `true`, git + will transparently follow any redirect issued by a server it + encounters. If set to `false`, git will treat all redirects as + errors. If set to `initial`, git will follow redirects only for + the initial request to a remote, but not for subsequent + follow-up HTTP requests. Since git uses the redirected URL as + the base for the follow-up requests, this is generally + sufficient. The default is `initial`. + +http..*:: + Any of the http.* options above can be applied selectively to some URLs. + For a config key to match a URL, each element of the config key is + compared to that of the URL, in the following order: ++ +-- +. Scheme (e.g., `https` in `https://example.com/`). This field + must match exactly between the config key and the URL. + +. Host/domain name (e.g., `example.com` in `https://example.com/`). + This field must match between the config key and the URL. It is + possible to specify a `*` as part of the host name to match all subdomains + at this level. `https://*.example.com/` for example would match + `https://foo.example.com/`, but not `https://foo.bar.example.com/`. + +. Port number (e.g., `8080` in `http://example.com:8080/`). + This field must match exactly between the config key and the URL. + Omitted port numbers are automatically converted to the correct + default for the scheme before matching. + +. Path (e.g., `repo.git` in `https://example.com/repo.git`). The + path field of the config key must match the path field of the URL + either exactly or as a prefix of slash-delimited path elements. This means + a config key with path `foo/` matches URL path `foo/bar`. A prefix can only + match on a slash (`/`) boundary. Longer matches take precedence (so a config + key with path `foo/bar` is a better match to URL path `foo/bar` than a config + key with just path `foo/`). + +. User name (e.g., `user` in `https://user@example.com/repo.git`). If + the config key has a user name it must match the user name in the + URL exactly. If the config key does not have a user name, that + config key will match a URL with any user name (including none), + but at a lower precedence than a config key with a user name. +-- ++ +The list above is ordered by decreasing precedence; a URL that matches +a config key's path is preferred to one that matches its user name. For example, +if the URL is `https://user@example.com/foo/bar` a config key match of +`https://example.com/foo` will be preferred over a config key match of +`https://user@example.com`. ++ +All URLs are normalized before attempting any matching (the password part, +if embedded in the URL, is always ignored for matching purposes) so that +equivalent URLs that are simply spelled differently will match properly. +Environment variable settings always override any matches. The URLs that are +matched against are those given directly to Git commands. This means any URLs +visited as a result of a redirection do not participate in matching. -- cgit 1.4.1
