2021-01-11templates: Add fileExists and httpError template actionsMatthew Holt
The httpError function isn't particularly useful until https://github.com/golang/go/issues/34201 is fixed in the Go standard lib.
2021-01-11requestbody: Allow overwriting remote addressMatthew Holt
An experimental feature, let's see if it's useful.
2021-01-11rewrite: Use RawPath instead of Path (fix #3596) (#3918)go-d
Prevent information loss, i.e. the encoded form that was sent by the client, when using URL strip/replace.
2021-01-05caddyfile: Refactor unmarshaling of module tokensMatthew Holt
Eliminates a fair amount of repeated code
2021-01-04reverseproxy: Caddyfile health check headers, host header support (#3948)yaxin
* reverse_proxy: 1.health check headers can be set through Caddyfile using health_headers directive; 2.health check header host can be set properly * reverse_proxy: replace example with syntax definition inline health_headers directive parse function * bugfix: change caddyfile_adapt testcase file from space to tab * reverseproxy: modify health_header value document as optional and add more test cases
2021-01-04caddyfile: Introduce basic linting and fmt check (#3923)Matt Holt
* caddyfile: Introduce basic linting and fmt check This will help encourage people to keep their Caddyfiles tidy. * Remove unrelated tests I am not sure that testing the output of warnings here is quite the right idea; these tests are just for syntax and parsing success.
2020-12-30fileserver: Fix "go up" links in browse listings (closes #3942)Matthew Holt
At some point we changed how paths are represented down the function calls of browse listings and forgot to update the canGoUp logic. I think this is right? It's simpler now.
2020-12-14reverseproxy: Minor lint fixesMatthew Holt
2020-12-10caddyhttp: Optionally use forwarded IP for remote_ip matcherMatthew Holt
The remote_ip matcher was reading the X-Forwarded-For header by default, but this behavior was not documented in anything that was released. This is also a less secure default, as it is trivially easy to spoof request headers. Reading IPs from that header should be optional, and it should not be the default. This is technically a breaking change, but anyone relying on the undocumented behavior was just doing so by coincidence/luck up to this point since it was never in any released documentation. We'll still add a mention in the release notes about this.
2020-12-10caddyhttp: Clean up internal auto-HTTPS redirect codeMatthew Holt
Refactor redirect route creation into own function. Improve condition for appending port. Fixes a bug manifested through new test case: TestAutoHTTPRedirectsWithHTTPListenerFirstInAddresses

2020-12-02caddyhttp: Optimize large host matchersMatthew Holt
2020-12-01caddyauth: Use buffered channel passed to signal.Notify (#3895)Cuong Manh Le
The docs at os/signal.Notify warn about this signal delivery loss bug at https://golang.org/pkg/os/signal/#Notify, which says: Package signal will not block sending to c: the caller must ensure that c has sufficient buffer space to keep up with the expected signal rate. For a channel used for notification of just one signal value, a buffer of size 1 is sufficient. Caught by a static analysis tool from Orijtech, Inc. called "sigchanyzer"

2020-11-20headers: Support default header values in Caddyfile with '?' (#3807)Gilbert Gilb's
* 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 Co-authored-by: Matthew Holt <mholt@users.noreply.github.com> Co-authored-by: Денис Телюх <telyukh.denis@gmail.com>
2020-11-18caddyhttp: Return error if error handling errorMatthew Holt
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.

2020-11-13basicauth: Minor internal improvements (#3861)Aurelia
* nitpicks and small improvements in basicauth module 1: roll two if statements into one, since err will be nil in the second case anyhow 2: unlock cache mutex after reading the key, as this happens by-value and reduces code complexity 3: switch cache sync.Mutex to sync.RWMutex for better concurrency on cache fast track * allocate the right kind of mutex

2020-10-31caddyauth: Prevent user enumeration by timingMatthew Holt
Always follow the code path of hashing and comparing a plaintext password even if the account is not found by the given username; this ensures that similar CPU cycles are spent for both valid and invalid usernames. Thanks to @tylerlm for helping and looking into this!
