reverseproxy: Handle "operation was canceled" errors (#3816)
* fix(caddy): Avoid "operation was canceled" errors

- Also add error handling for StatusGatewayTimeout

* revert(caddy): Revert 504 handling

- This will potentially break load balancing and health checks

* Handle client cancellation as different error

headers: Support default header values in Caddyfile with '?' (#3807)
* implement default values for header directive

closes #3804

* remove `set_default` header op and rely on "require" handler instead

This has the following advantages over the previous attempt:

- It does not introduce a new operation for headers, but rather nicely
  extends over an existing feature in the header handler.
- It removes the need to specify the header as "deferred" because it is
  already implicitely deferred by the use of the require handler. This
  should be less confusing to the user.

* add integration test for header directive in caddyfile

* bubble up errors when parsing caddyfile header directive

* don't export unnecessarily and don't canonicalize headers unnecessarily

* fix response headers not passed in blocks

* caddyfile: fix clash when using default header in block

Each header is now set in a separate handler so that it doesn't clash
with other headers set/added/deleted in the same block.

* caddyhttp: New idle_timeout default of 5m

* reverseproxy: fix random hangs on http/2 requests with server push (#3875)

see https://github.com/golang/go/issues/42534

* Refactor and cleanup with improvements

* More specific link

caddyhttp: Return error if error handling error
Before, if there was an error in the error handler, we would not write a
status code, which resulted in Go writing a 200 for us by default, which
does not make sense when there's an error. Now we write the second
error's status if available, otherwise 500.

caddyauth: Prevent user enumeration by timing
Always follow the code path of hashing and comparing a plaintext
password even if the account is not found by the given username; this

fileserver: Improve file hiding logic for directories and prefixes
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.

caddytls: Add support for ZeroSSL; add Caddyfile support for issuers (#3633)
* 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

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

firstSplit. So a new test function is better for that.

fastcgi: Make sure splitPos handles empty SplitPath correctly (#3491)
In commit f2ce81c, support for multiple path splitters was added. The
type of SplitPath changed from string to []string, and splitPos was
changed to loop through all values in SplitPath.

Before that commit, if SplitPath was empty, strings.Index returned 0 and
PATH_INFO was set correctly in buildEnv.

Currently, however, splitPos returns -1 for empty values of SplitPath,
behaving as if a split position could not be found at all. PATH_INFO is
then never set in buildEnv and remains empty.

Restore the old behaviour by explicitly checking whether SplitPath is
empty and returning 0 in splitPos.

Closes #3490

reverseproxy: Don't overwrite existing X-Forwarded-Proto header
Correct behavior is not well defined because this is a non-standard
header field. This could be a "hop-by-hop" field much like
X-Forwarded-For is, but even our X-Forwarded-For implementation
preserves prior entries. Or, it could be best to preserve the original
value from the first hop, representing the protocol as facing the
client.

Let's try it the other way for a bit and see how it goes.

a507a5bbc7 reverseproxy: Remove circuitbreaker module (see #3331)
Moving to https://github.com/caddyserver/circuitbreaker

Nobody was using it anyway -- it works well, but something got fumbled
in a refactoring *months* ago. Turns out that we forgot the interface
guards AND botched a method name (my bad) - Ok() should have been OK().
So it would always have thrown a runtime panic if it tried to be loaded.
The module itself works well, but obviously nobody used it because
nobody reported the error. Fixing this while we move it to the new repo.

Removing this removes the last Bazaar/Launchpad dependency (I think).

httpcaddyfile: Add nil check to prevent panic, fix validation logic
Panic would happen if an automation policy was specified in a singular
server block that had no hostnames in its address. Definitely an edge
case.

Fixed a bug related to checking for server blocks with a host-less key
that tried to make an automation policy. Previously if you had only two
server blocks like ":443" and another one at ":80", the one at ":443"
could not create a TLS automation policy because it thought it would
interfere with TLS automation for the block at ":80", but obviously that
key doesn't enable TLS because it is on the HTTP port. So now we are a
little smarter and count only non-HTTP-empty-hostname keys.

Also fixed a bug so that a key like "https://:1234" is sure to have TLS

slightly; the previous conditions were too strict, requiring there to be
a TLS conn policy already or a default SNI to be non-empty.)

core: Don't return error on RegisterModule() and RegisterAdapter()
These functions are called at init-time, and their inputs are hard-coded
so there are no environmental or user factors that could make it fail
or succeed; the error return values are often ignored, and when they're
not, they are usually a fatal error anyway. To ensure that a programmer
mistake is not missed, we now panic instead.

httpcaddyfile: Put root directive first, before redir and rewrite
See https://caddy.community/t/v2-match-any-path-but-files/7326/8?u=matt

If rewrites (or redirects, for that matter) match on file existence,
the file matcher would need to know the root of the site.

Making this change implies that root directives that depend on rewritten
URIs will not work as expected. However, I think this is very uncommon,
and am not sure I have ever seen that. Usually, dynamic roots are based
on host, not paths or query strings.

I suspect that rewrites based on file existence will be more common than
roots based on rewritten URIs, so I am moving root to be the first in
the list.

Users can always override this ordering with the 'order' global option.

tls/http: Fix auto-HTTPS logic w/rt default issuers (fixes #3164)
The comments in the code should explain the new logic thoroughly.
The basic problem for the issue was that we were overriding a catch-all
automation policy's explicitly-configured issuer with our own, for names
that we thought looked like public names. In other words, one could
configure an internal issuer for all names, but then our auto HTTPS
would create a new policy for public-looking names that uses the
default ACME issuer, because we assume public<==>ACME and
nonpublic<==>Internal, but that is not always the case. The new logic
still assumes nonpublic<==>Internal (on catch-all policies only), but
no longer assumes that public-looking names always use an ACME issuer.

Also fix a bug where HTTPPort and HTTPSPort from the HTTP app weren't
being carried through to ACME issuers properly. It required a bit of
refactoring.

260982b2df reverse_proxy: Allow use of URL to specify scheme
This makes it more convenient to configure quick proxies that use HTTPS
but also introduces a lot of logical complexity. We have to do a lot of
verification for consistency and errors.

Path and query string is not supported (i.e. no rewriting).

Scheme and port can be inferred from each other if HTTP(S)/80/443.
If omitted, defaults to HTTP.

Any explicit transport config must be consistent with the upstream
schemes, and the upstream schemes must all match too.

But, this change allows a config that used to require this:

    reverse_proxy example.com:443 {
        transport http {
            tls
        }
    }

to be reduced to this:

    reverse_proxy https://example.com

which is really nice syntactic sugar (and is reminiscent of Caddy 1).

caddyhttp: Add handler for unhandled errors in errorChain (#3063)
* Add handler for unhandled errors in errorChain

Currently, when an error chain is defined, the default error handler is
bypassed entirely - even if the error chain doesn't handle every error.
This results in pages returning a blank 200 OK page.

For instance, it's possible for an error chain to match on the error
status code and only handle a certain subtype of errors (like 403s). In
this case, we'd want any other errors to still go through the default
handler and return an empty page with the status code.

This PR changes the "suffix handler" passed to errorChain.Compile to
set the status code of the response to the error status code.

Fixes #3053

* Move the errorHandlerChain middleware to variable

15bf9c196c caddyfile: Refactor; NewFromNextSegment(); fix repeated matchers
Now multiple instances of the same matcher can be used within a named
matcher without overwriting previous ones.

Remove Starlark, for now
This is temporary as we prepare for a stable v2 release. We don't want
to make promises we don't know we can keep, and the Starlark integration
deserves much more focused attention which resources and funding do not
currently permit. When the project is financially stable, I will be able
to revisit this properly and add flexible, robust Starlark scripting
support to Caddy 2.

http: Split 2-phase auto-HTTPS into 3 phases
This is necessary to avoid a race for sockets. Both the HTTP servers and
CertMagic solvers will try to bind the HTTP/HTTPS ports, but we need to
make sure that our HTTP servers bind first. This is kind of a new thing
now that management is async in Caddy 2.

Also update to CertMagic 0.9.2, which fixes some async use cases at
scale.

header: caddyfile: Defer header operations for deletions or manually
See https://caddy.community/t/caddy-server-that-returns-only-ip-address-as-text/6928/6?u=matt

In most cases, we will want to apply header operations immediately,
rather than waiting until the response is written. The exceptions are
generally going to be if we are deleting a header field or if a field is
to be overwritten. We now automatically defer header ops if deleting a
header field, and allow the user to manually enable deferred mode with
the defer subdirective.

rewrite: Prepend "/" if missing from strip path prefix
Paths always begin with a slash, and omitting the leading slash could be
convenient to avoid confusion with a path matcher in the Caddyfile. I do
not think there would be any harm to implicitly add the leading slash.

* v2: add documentation for circuit breaker config and "random selection" load balancing policy

* v2: rename circuit breaker config inline key from `type` to `breaker` to avoid json key clash between the `circuit_breaker` type and the `type` field of the generic circuit breaker Config struct used by circuit breaking implementations

* v2: restore the circuit breaker inline key to `type` and rename the name circuit breaker config field from `Type` to `Factor`

httpcaddyfile: Fix nested blocks; add handle directive; refactor
The fix that was initially put forth in #2971 was good, but only for
up to one layer of nesting. The real problem was that we forgot to
increment nesting when already inside a block if we saw another open
curly brace that opens another block (dispenser.go L157-158).

The new 'handle' directive allows HTTP Caddyfiles to be designed more
like nginx location blocks if the user prefers. Inside a handle block,
directives are still ordered just like they are outside of them, but
handler blocks at a given level of nesting are mutually exclusive.

This work benefitted from some refactoring and cleanup.

rewrite: Make URI modifications more transactional (#2891)
Before, modifying the path might have affected how a new query string
was built if the query string relied on the path. Now, we build each
component in isolation and only change the URI on the request later.

Also, prevent trailing & in query string.
