2020-09-11httpcaddyfile: Properly record whether we added catch-all conn policyMatthew Holt
We recently introduced `if !cp.SettingsEmpty()` which conditionally adds the connection policy to the list. If the condition evaluates to false, the policy wouldn't actually be added, even if hasCatchAllTLSConnPolicy was set to true on the previous line. Now we set that variable in accordance with whether we actually add the policy. While debugging this I noticed that catch-all policies added early in that loop (i.e. not at the end if we later determine we need one) are not always at the end of the list. They should be, though, since they are selected by which one matches first, and having a catch-all first would nullify any more specific ones later in the list. So I added a sort in consolidateConnPolicies to take care of that. Should fix #3670 and https://caddy.community/t/combining-on-demand-tls-with-custom-ssl-certs-doesnt-seem-to-work-in-2-1-1/9719 but I won't know for sure until somebody verifies it, since at least in the GitHub issue there is not yet enough information (the configs are redacted).
2020-09-11fileserver: Fix new file hide tests on Windows (#3719)Matt Holt
2020-09-11fileserver: Improve file hiding logic for directories and prefixesMatthew Holt
Now, a filename to hide that is specified without a path separator will count as hidden if it appears in any component of the file path (not only the last component); semantically, this means hiding a file by only its name (without any part of a path) will hide both files and folders, e.g. hiding ".git" will hide "/.git" and also "/.git/foo". We also do prefix matching so that hiding "/.git" will hide "/.git" and "/.git/foo" but not "/.gitignore". The remaining logic is a globular match like before.

2020-08-11caddytls: Add support for ZeroSSL; add Caddyfile support for issuers (#3633)Matt Holt
* caddytls: Add support for ZeroSSL; add Caddyfile support for issuers Configuring issuers explicitly in a Caddyfile is not easily compatible with existing ACME-specific parameters such as email or acme_ca which infer the kind of issuer it creates (this is complicated now because the ZeroSSL issuer wraps the ACME issuer)... oh well, we can revisit that later if we need to. New Caddyfile global option: { cert_issuer <name> ... } Or, alternatively, as a tls subdirective: tls { issuer <name> ... } For example, to use ZeroSSL with an API key: { cert_issuser zerossl API_KEY } For now, that still uses ZeroSSL's ACME endpoint; it fetches EAB credentials for you. You can also provide the EAB credentials directly just like any other ACME endpoint: { cert_issuer acme { eab KEY_ID MAC_KEY } } All these examples use the new global option (or tls subdirective). You can still use traditional/existing options with ZeroSSL, since it's just another ACME endpoint: { acme_ca https://acme.zerossl.com/v2/DV90 acme_eab KEY_ID MAC_KEY } That's all there is to it. You just can't mix-and-match acme_* options with cert_issuer, because it becomes confusing/ambiguous/complicated to merge the settings. * Fix broken test This test was asserting buggy behavior, oops - glad this branch both discovers and fixes the bug at the same time! * Fix broken test (post-merge) * Update modules/caddytls/acmeissuer.go Fix godoc comment Co-authored-by: Francis Lavoie <lavofr@gmail.com> * Add support for ZeroSSL's EAB-by-email endpoint Also transform the ACMEIssuer into ZeroSSLIssuer implicitly if set to the ZeroSSL endpoint without EAB (the ZeroSSLIssuer is needed to generate EAB if not already provided); this is now possible with either an API key or an email address. * go.mod: Use latest certmagic, acmez, and x/net * Wrap underlying logic rather than repeating it Oops, duh * Form-encode email info into request body for EAB endpoint Co-authored-by: Francis Lavoie <lavofr@gmail.com>
