our expectations for participants within the **NYTimes/gziphandler** community, as well as steps to reporting unacceptable behavior. We are committed to providing a welcoming and inspiring community for all and expect our code of conduct to be honored. Anyone who violates this code of conduct may be banned from the community. + +Our open source community strives to: + +* **Be friendly and patient.** +* **Be welcoming**: We strive to be a community that welcomes and supports people of all backgrounds and identities. This includes, but is not limited to members of any race, ethnicity, culture, national origin, colour, immigration status, social and economic class, educational level, sex, sexual orientation, gender identity and expression, age, size, family status, political belief, religion, and mental and physical ability. +* **Be considerate**: Your work will be used by other people, and you in turn will depend on the work of others. Any decision you take will affect users and colleagues, and you should take those consequences into account when making decisions. Remember that we're a world-wide community, so you might not be communicating in someone else's primary language. +* **Be respectful**: Not all of us will agree all the time, but disagreement is no excuse for poor behavior and poor manners. We might all experience some frustration now and then, but we cannot allow that frustration to turn into a personal attack. It’s important to remember that a community where people feel uncomfortable or threatened is not a productive one. +* **Be careful in the words that we choose**: we are a community of professionals, and we conduct ourselves professionally. Be kind to others. Do not insult or put down other participants. Harassment and other exclusionary behavior aren't acceptable. +* **Try to understand why we disagree**: Disagreements, both social and technical, happen all the time. It is important that we resolve disagreements and differing views constructively. Remember that we’re different. The strength of our community comes from its diversity, people from a wide range of backgrounds. Different people have different perspectives on issues. Being unable to understand why someone holds a viewpoint doesn’t mean that they’re wrong. Don’t forget that it is human to err and blaming each other doesn’t get us anywhere. Instead, focus on helping to resolve issues and learning from mistakes. + +## Definitions + +Harassment includes, but is not limited to: + +- Offensive comments related to gender, gender identity and expression, sexual orientation, disability, mental illness, neuro(a)typicality, physical appearance, body size, race, age, regional discrimination, political or religious affiliation +- Unwelcome comments regarding a person’s lifestyle choices and practices, including those related to food, health, parenting, drugs, and employment +- Deliberate misgendering. This includes deadnaming or persistently using a pronoun that does not correctly reflect a person's gender identity. You must address people by the name they give you when not addressing them by their username or handle +- Physical contact and simulated physical contact (eg, textual descriptions like “*hug*” or “*backrub*”) without consent or after a request to stop +- Threats of violence, both physical and psychological +- Incitement of violence towards any individual, including encouraging a person to commit suicide or to engage in self-harm +- Deliberate intimidation +- Stalking or following +- Harassing photography or recording, including logging online activity for harassment purposes +- Sustained disruption of discussion +- Unwelcome sexual attention, including gratuitous or off-topic sexual images or behaviour +- Pattern of inappropriate social contact, such as requesting/assuming inappropriate levels of intimacy with others +- Continued one-on-one communication after requests to cease +- Deliberate “outing” of any aspect of a person’s identity without their consent except as necessary to protect others from intentional abuse +- Publication of non-harassing private communication + +Our open source community prioritizes marginalized people’s safety over privileged people’s comfort. We will not act on complaints regarding: + +- ‘Reverse’ -isms, including ‘reverse racism,’ ‘reverse sexism,’ and ‘cisphobia’ +- Reasonable communication of boundaries, such as “leave me alone,” “go away,” or “I’m not discussing this with you” +- Refusal to explain or debate social justice concepts +- Communicating in a ‘tone’ you don’t find congenial +- Criticizing racist, sexist, cissexist, or otherwise oppressive behavior or assumptions + + +### Diversity Statement + +We encourage everyone to participate and are committed to building a community for all. Although we will fail at times, we seek to treat everyone both as fairly and equally as possible. Whenever a participant has made a mistake, we expect them to take responsibility for it. If someone has been harmed or offended, it is our responsibility to listen carefully and respectfully, and do our best to right the wrong. + +Although this list cannot be exhaustive, we explicitly honor diversity in age, gender, gender identity or expression, culture, ethnicity, language, national origin, political beliefs, profession, race, religion, sexual orientation, socioeconomic status, and technical ability. We will not tolerate discrimination based on any of the protected +characteristics above, including participants with disabilities. + +### Reporting Issues + +If you experience or witness unacceptable behavior—or have any other concerns—please report it by contacting us via **code@nytimes.com**. All reports will be handled with discretion. In your report please include: + +- Your contact information. +- Names (real, nicknames, or pseudonyms) of any individuals involved. If there are additional witnesses, please +include them as well. Your account of what occurred, and if you believe the incident is ongoing. If there is a publicly available record (e.g. a mailing list archive or a public IRC logger), please include a link. +- Any additional information that may be helpful. + +After filing a report, a representative will contact you personally, review the incident, follow up with any additional questions, and make a decision as to how to respond. If the person who is harassing you is part of the response team, they will recuse themselves from handling your incident. If the complaint originates from a member of the response team, it will be handled by a different member of the response team. We will respect confidentiality requests for the purpose of protecting victims of abuse. + +### Attribution & Acknowledgements + +We all stand on the shoulders of giants across many open source communities.

Implements Jim Idle's magic Sync mechanism in closures and optional +// subrules. E.g.,

+// +//
+// a : Sync ( stuff Sync )*
+// Sync : {consume to what can follow Sync}
+// 
+// +// At the start of a sub rule upon error, {@link //Sync} performs single +// token deletion, if possible. If it can't do that, it bails on the current +// rule and uses the default error recovery, which consumes until the +// reSynchronization set of the current rule. +// +//

If the sub rule is optional ({@code (...)?}, {@code (...)*}, or block +// with an empty alternative), then the expected set includes what follows +// the subrule.

+// +//

During loop iteration, it consumes until it sees a token that can start a +// sub rule or what follows loop. Yes, that is pretty aggressive. We opt to +// stay in the loop as long as possible.

+// +//

ORIGINS

+// +//

Previous versions of ANTLR did a poor job of their recovery within loops. +// A single mismatch token or missing token would force the parser to bail +// out of the entire rules surrounding the loop. So, for rule

+// +//
+// classfunc : 'class' ID '{' member* '}'
+// 
+// +// input with an extra token between members would force the parser to +// consume until it found the next class definition rather than the next +// member definition of the current class. +// +//

This functionality cost a little bit of effort because the parser has to +// compare token set at the start of the loop and at each iteration. If for +// some reason speed is suffering for you, you can turn off d +// functionality by simply overriding d method as a blank { }.

+// +func (d *DefaultErrorStrategy) Sync(recognizer Parser) { + // If already recovering, don't try to Sync + if d.InErrorRecoveryMode(recognizer) { + return + } + + s := recognizer.GetInterpreter().atn.states[recognizer.GetState()] + la := recognizer.GetTokenStream().LA(1) + + // try cheaper subset first might get lucky. seems to shave a wee bit off + nextTokens := recognizer.GetATN().NextTokens(s, nil) + if nextTokens.contains(TokenEpsilon) || nextTokens.contains(la) { + return + } + + switch s.GetStateType() { + case ATNStateBlockStart, ATNStateStarBlockStart, ATNStatePlusBlockStart, ATNStateStarLoopEntry: + // Report error and recover if possible + if d.SingleTokenDeletion(recognizer) != nil { + return + } + panic(NewInputMisMatchException(recognizer)) + case ATNStatePlusLoopBack, ATNStateStarLoopBack: + d.ReportUnwantedToken(recognizer) + expecting := NewIntervalSet() + expecting.addSet(recognizer.GetExpectedTokens()) + whatFollowsLoopIterationOrRule := expecting.addSet(d.getErrorRecoverySet(recognizer)) + d.consumeUntil(recognizer, whatFollowsLoopIterationOrRule) + default: + // do nothing if we can't identify the exact kind of ATN state + } +} + +// This is called by {@link //ReportError} when the exception is a +// {@link NoViableAltException}. +// +// @see //ReportError +// +// @param recognizer the parser instance +// @param e the recognition exception +// +func (d *DefaultErrorStrategy) ReportNoViableAlternative(recognizer Parser, e *NoViableAltException) { + tokens := recognizer.GetTokenStream() + var input string + if tokens != nil { + if e.startToken.GetTokenType() == TokenEOF { + input = "" + } else { + input = tokens.GetTextFromTokens(e.startToken, e.offendingToken) + } + } else { + input = "" + } + msg := "no viable alternative at input " + d.escapeWSAndQuote(input) + recognizer.NotifyErrorListeners(msg, e.offendingToken, e) +} + +// +// This is called by {@link //ReportError} when the exception is an +// {@link InputMisMatchException}. +// +// @see //ReportError +// +// @param recognizer the parser instance +// @param e the recognition exception +// +func (this *DefaultErrorStrategy) ReportInputMisMatch(recognizer Parser, e *InputMisMatchException) { + msg := "mismatched input " + this.GetTokenErrorDisplay(e.offendingToken) + + " expecting " + e.getExpectedTokens().StringVerbose(recognizer.GetLiteralNames(), recognizer.GetSymbolicNames(), false) + recognizer.NotifyErrorListeners(msg, e.offendingToken, e) +} + +// +// This is called by {@link //ReportError} when the exception is a +// {@link FailedPredicateException}. +// +// @see //ReportError +// +// @param recognizer the parser instance +// @param e the recognition exception +// +func (d *DefaultErrorStrategy) ReportFailedPredicate(recognizer Parser, e *FailedPredicateException) { + ruleName := recognizer.GetRuleNames()[recognizer.GetParserRuleContext().GetRuleIndex()] + msg := "rule " + ruleName + " " + e.message + recognizer.NotifyErrorListeners(msg, e.offendingToken, e) +} + +// This method is called to Report a syntax error which requires the removal +// of a token from the input stream.

This method is called when {@link //singleTokenInsertion} identifies +// single-token insertion as a viable recovery strategy for a mismatched +// input error.

+// +//

The default implementation simply returns if the handler is already in +// error recovery mode. Otherwise, it calls {@link //beginErrorCondition} to +// enter error recovery mode, followed by calling +// {@link Parser//NotifyErrorListeners}.

The default implementation attempts to recover from the mismatched input +// by using single token insertion and deletion as described below. If the +// recovery attempt fails, d method panics an +// {@link InputMisMatchException}.

+// +//

EXTRA TOKEN (single token deletion)

+// +//

{@code LA(1)} is not what we are looking for. If {@code LA(2)} has the +// right token, however, then assume {@code LA(1)} is some extra spurious +// token and delete it. Then consume and return the next token (which was +// the {@code LA(2)} token) as the successful result of the Match operation.

+// +//

This recovery strategy is implemented by {@link +// //singleTokenDeletion}.

+// +//

MISSING TOKEN (single token insertion)

+// +//

If current token (at {@code LA(1)}) is consistent with what could come +// after the expected {@code LA(1)} token, then assume the token is missing +// and use the parser's {@link TokenFactory} to create it on the fly. The +// "insertion" is performed by returning the created token as the successful +// result of the Match operation.

+// +//

This recovery strategy is implemented by {@link +// //singleTokenInsertion}.

+// +//

EXAMPLE

+// +//

For example, Input {@code i=(3} is clearly missing the {@code ')'}. When +// the parser returns from the nested call to {@code expr}, it will have +// call chain:

+// +//
+// stat &rarr expr &rarr atom
+// 
+// +// and it will be trying to Match the {@code ')'} at d point in the +// derivation: +// +//
+// => ID '=' '(' INT ')' ('+' atom)* ''
+// ^
+// 
+// +// The attempt to Match {@code ')'} will fail when it sees {@code ''} and +// call {@link //recoverInline}. To recover, it sees that {@code LA(1)==''} +// is in the set of tokens that can follow the {@code ')'} token reference +// in rule {@code atom}. It can assume that you forgot the {@code ')'}. +// +func (d *DefaultErrorStrategy) RecoverInline(recognizer Parser) Token { + // SINGLE TOKEN DELETION + MatchedSymbol := d.SingleTokenDeletion(recognizer) + if MatchedSymbol != nil { + // we have deleted the extra token. + // now, move past ttype token as if all were ok + recognizer.Consume() + return MatchedSymbol + } + // SINGLE TOKEN INSERTION + if d.SingleTokenInsertion(recognizer) { + return d.GetMissingSymbol(recognizer) + } + // even that didn't work must panic the exception + panic(NewInputMisMatchException(recognizer)) +} + +// +// This method implements the single-token insertion inline error recovery +// strategy. It is called by {@link //recoverInline} if the single-token +// deletion strategy fails to recover from the mismatched input. If this +// method returns {@code true}, {@code recognizer} will be in error recovery +// mode. +// +//

This method determines whether or not single-token insertion is viable by +// checking if the {@code LA(1)} input symbol could be successfully Matched +// if it were instead the {@code LA(2)} symbol. If d method returns +// {@code true}, the caller is responsible for creating and inserting a +// token with the correct type to produce d behavior.

If the single-token deletion is successful, d method calls +// {@link //ReportUnwantedToken} to Report the error, followed by +// {@link Parser//consume} to actually "delete" the extraneous token. Then, +// before returning {@link //ReportMatch} is called to signal a successful +// Match.

    +//
  • The usual SLL+LL fallback upon SLL conflict
  • +//
  • Pure SLL without LL fallback
  • +//
+// +//

COMBINED SLL+LL PARSING

+// +//

When LL-fallback is enabled upon SLL conflict, correct predictions are +// ensured regardless of how the termination condition is computed by this +// method. Due to the substantially higher cost of LL prediction, the +// prediction should only fall back to LL when the additional lookahead +// cannot lead to a unique SLL prediction.

+// +//

Assuming combined SLL+LL parsing, an SLL configuration set with only +// conflicting subsets should fall back to full LL, even if the +// configuration sets don't resolve to the same alternative (e.g. +// {@code {1,2}} and {@code {3,4}}. If there is at least one non-conflicting +// configuration, SLL could continue with the hopes that more lookahead will +// resolve via one of those non-conflicting configurations.

+// +//

Here's the prediction termination rule them: SLL (for SLL+LL parsing) +// stops when it sees only conflicting configuration subsets. In contrast, +// full LL keeps going when there is uncertainty.

+// +//

HEURISTIC

+// +//

As a heuristic, we stop prediction when we see any conflicting subset +// unless we see a state that only has one alternative associated with it. +// The single-alt-state thing lets prediction continue upon rules like +// (otherwise, it would admit defeat too soon):

+// +//

{@code [12|1|[], 6|2|[], 12|2|[]]. s : (ID | ID ID?) '' }

+// +//

When the ATN simulation reaches the state before {@code ''}, it has a +// DFA state that looks like: {@code [12|1|[], 6|2|[], 12|2|[]]}. Naturally +// {@code 12|1|[]} and {@code 12|2|[]} conflict, but we cannot stop +// processing this node because alternative to has another way to continue, +// via {@code [6|2|[]]}.

+// +//

It also let's us continue for this rule:

+// +//

{@code [1|1|[], 1|2|[], 8|3|[]] a : A | A | A B }

+// +//

After Matching input A, we reach the stop state for rule A, state 1. +// State 8 is the state right before B. Clearly alternatives 1 and 2 +// conflict and no amount of further lookahead will separate the two. +// However, alternative 3 will be able to continue and so we do not stop +// working on this state. In the previous example, we're concerned with +// states associated with the conflicting alternatives. Here alt 3 is not +// associated with the conflicting configs, but since we can continue +// looking for input reasonably, don't declare the state done.

+// +//

PURE SLL PARSING

+// +//

To handle pure SLL parsing, all we have to do is make sure that we +// combine stack contexts for configurations that differ only by semantic +// predicate. From there, we can do the usual SLL termination heuristic.

+// +//

PREDICATES IN SLL+LL PARSING

+// +//

SLL decisions don't evaluate predicates until after they reach DFA stop +// states because they need to create the DFA cache that works in all +// semantic situations. In contrast, full LL evaluates predicates collected +// during start state computation so it can ignore predicates thereafter. +// This means that SLL termination detection can totally ignore semantic +// predicates.

+// +//

Implementation-wise, {@link ATNConfigSet} combines stack contexts but not +// semantic predicate contexts so we might see two configurations like the +// following.

+// +//

{@code (s, 1, x, {}), (s, 1, x', {p})}

+// +//

Before testing these configurations against others, we have to merge +// {@code x} and {@code x'} (without modifying the existing configurations). +// For example, we test {@code (x+x')==x''} when looking for conflicts in +// the following configurations.

+// +//

{@code (s, 1, x, {}), (s, 1, x', {p}), (s, 2, x'', {})}

+// +//

If the configuration set has predicates (as indicated by +// {@link ATNConfigSet//hasSemanticContext}), this algorithm makes a copy of +// the configurations to strip out all of the predicates so that a standard +// {@link ATNConfigSet} will merge everything ignoring predicates.

+// +func PredictionModehasSLLConflictTerminatingPrediction(mode int, configs ATNConfigSet) bool { + // Configs in rule stop states indicate reaching the end of the decision + // rule (local context) or end of start rule (full context). If all + // configs meet this condition, then none of the configurations is able + // to Match additional input so we terminate prediction. + // + if PredictionModeallConfigsInRuleStopStates(configs) { + return true + } + // pure SLL mode parsing + if mode == PredictionModeSLL { + // Don't bother with combining configs from different semantic + // contexts if we can fail over to full LL costs more time + // since we'll often fail over anyway. + if configs.HasSemanticContext() { + // dup configs, tossing out semantic predicates + dup := NewBaseATNConfigSet(false) + for _, c := range configs.GetItems() { + + // NewBaseATNConfig({semanticContext:}, c) + c = NewBaseATNConfig2(c, SemanticContextNone) + dup.Add(c, nil) + } + configs = dup + } + // now we have combined contexts for configs with dissimilar preds + } + // pure SLL or combined SLL+LL mode parsing + altsets := PredictionModegetConflictingAltSubsets(configs) + return PredictionModehasConflictingAltSet(altsets) && !PredictionModehasStateAssociatedWithOneAlt(configs) +} + +// Checks if any configuration in {@code configs} is in a +// {@link RuleStopState}.

Can we stop looking ahead during ATN simulation or is there some +// uncertainty as to which alternative we will ultimately pick, after +// consuming more input? Even if there are partial conflicts, we might know +// that everything is going to resolve to the same minimum alternative. That +// means we can stop since no more lookahead will change that fact. On the +// other hand, there might be multiple conflicts that resolve to different +// minimums. That means we need more look ahead to decide which of those +// alternatives we should predict.

+// +//

The basic idea is to split the set of configurations {@code C}, into +// conflicting subsets {@code (s, _, ctx, _)} and singleton subsets with +// non-conflicting configurations. Two configurations conflict if they have +// identical {@link ATNConfig//state} and {@link ATNConfig//context} values +// but different {@link ATNConfig//alt} value, e.g. {@code (s, i, ctx, _)} +// and {@code (s, j, ctx, _)} for {@code i!=j}.

+// +//

Reduce these configuration subsets to the set of possible alternatives. +// You can compute the alternative subsets in one pass as follows:

+// +//

{@code A_s,ctx = {i | (s, i, ctx, _)}} for each configuration in +// {@code C} holding {@code s} and {@code ctx} fixed.

+// +//

Or in pseudo-code, for each configuration {@code c} in {@code C}:

+// +//
+// map[c] U= c.{@link ATNConfig//alt alt} // map hash/equals uses s and x, not
+// alt and not pred
+// 
+// +//

The values in {@code map} are the set of {@code A_s,ctx} sets.

+// +//

If {@code |A_s,ctx|=1} then there is no conflict associated with +// {@code s} and {@code ctx}.

+// +//

Reduce the subsets to singletons by choosing a minimum of each subset. If +// the union of these alternative subsets is a singleton, then no amount of +// more lookahead will help us. We will always pick that alternative. If, +// however, there is more than one alternative, then we are uncertain which +// alternative to predict and must continue looking for resolution. We may +// or may not discover an ambiguity in the future, even if there are no +// conflicting subsets this round.

+// +//

The biggest sin is to terminate early because it means we've made a +// decision but were uncertain as to the eventual outcome. We haven't used +// enough lookahead. On the other hand, announcing a conflict too late is no +// big deal you will still have the conflict. It's just inefficient. It +// might even look until the end of file.

+// +//

No special consideration for semantic predicates is required because +// predicates are evaluated on-the-fly for full LL prediction, ensuring that +// no configuration contains a semantic context during the termination +// check.

+// +//

CONFLICTING CONFIGS

+// +//

Two configurations {@code (s, i, x)} and {@code (s, j, x')}, conflict +// when {@code i!=j} but {@code x=x'}. Because we merge all +// {@code (s, i, _)} configurations together, that means that there are at +// most {@code n} configurations associated with state {@code s} for +// {@code n} possible alternatives in the decision. The merged stacks +// complicate the comparison of configuration contexts {@code x} and +// {@code x'}. Sam checks to see if one is a subset of the other by calling +// merge and checking to see if the merged result is either {@code x} or +// {@code x'}. If the {@code x} associated with lowest alternative {@code i} +// is the superset, then {@code i} is the only possible prediction since the +// others resolve to {@code min(i)} as well. However, if {@code x} is +// associated with {@code j>i} then at least one stack configuration for +// {@code j} is not in conflict with alternative {@code i}. The algorithm +// should keep going, looking for more lookahead due to the uncertainty.

+// +//

For simplicity, I'm doing a equality check between {@code x} and +// {@code x'} that lets the algorithm continue to consume lookahead longer +// than necessary. The reason I like the equality is of course the +// simplicity but also because that is the test you need to detect the +// alternatives that are actually in conflict.

+// +//

CONTINUE/STOP RULE

+// +//

Continue if union of resolved alternative sets from non-conflicting and +// conflicting alternative subsets has more than one alternative. We are +// uncertain about which alternative to predict.

+// +//

The complete set of alternatives, {@code [i for (_,i,_)]}, tells us which +// alternatives are still in the running for the amount of input we've +// consumed at this point. The conflicting sets let us to strip away +// configurations that won't lead to more states because we resolve +// conflicts to the configuration with a minimum alternate for the +// conflicting set.

+// +//

+// You can insert stuff, replace, and delete chunks. Note that the operations +// are done lazily--only if you convert the buffer to a {@link String} with +// {@link TokenStream#getText()}. This is very efficient because you are not +// moving data around all the time. As the buffer of tokens is converted to +// strings, the {@link #getText()} method(s) scan the input token stream and +// check to see if there is an operation at the current index. If so, the +// operation is done and then normal {@link String} rendering continues on the +// buffer. This is like having multiple Turing machine instruction streams +// (programs) operating on a single input tape. :)

+//

+ +// This rewriter makes no modifications to the token stream. It does not ask the +// stream to fill itself up nor does it advance the input cursor. The token +// stream {@link TokenStream#index()} will return the same value before and +// after any {@link #getText()} call.

+ +//

+// The rewriter only works on tokens that you have in the buffer and ignores the +// current input cursor. If you are buffering tokens on-demand, calling +// {@link #getText()} halfway through the input will only do rewrites for those +// tokens in the first half of the file.

+ +//

+// Since the operations are done lazily at {@link #getText}-time, operations do +// not screw up the token index values. That is, an insert operation at token +// index {@code i} does not change the index values for tokens +// {@code i}+1..n-1.

+ +//

+// Because operations never actually alter the buffer, you may always get the +// original token stream back without undoing anything. Since the instructions +// are queued up, you can easily simulate transactions and roll back any changes +// if there is an error just by removing instructions. For example,

+ +//
+// CharStream input = new ANTLRFileStream("input");
+// TLexer lex = new TLexer(input);
+// CommonTokenStream tokens = new CommonTokenStream(lex);
+// T parser = new T(tokens);
+// TokenStreamRewriter rewriter = new TokenStreamRewriter(tokens);
+// parser.startRule();
+// 
+ +//

+// Then in the rules, you can execute (assuming rewriter is visible):

+ +//
+// Token t,u;
+// ...
+// rewriter.insertAfter(t, "text to put after t");}
+// rewriter.insertAfter(u, "text after u");}
+// System.out.println(rewriter.getText());
+// 
+ +//

+// You can also have multiple "instruction streams" and get multiple rewrites +// from a single pass over the input. Just name the instruction streams and use +// that name again when printing the buffer. This could be useful for generating +// a C file and also its header file--all from the same buffer:

+ +//
+// rewriter.insertAfter("pass1", t, "text to put after t");}
+// rewriter.insertAfter("pass2", u, "text after u");}
+// System.out.println(rewriter.getText("pass1"));
+// System.out.println(rewriter.getText("pass2"));
+// 
+ +//

+// If you don't use named rewrite streams, a "default" stream is used as the +// first example shows.

A good place to activate this is a package init function or the main() function. + +`SetNilPtrAllowedByRequired` causes validation to pass when struct fields marked by `required` are set to nil. This is disabled by default for consistency, but some packages that need to be able to determine between `nil` and `zero value` state can use this. If disabled, both `nil` and `zero` values cause validation errors. + +```go +import "github.com/asaskevich/govalidator" + +func init() { + govalidator.SetFieldsRequiredByDefault(true) +} +``` + +Here's some code to explain it: +```go +// this struct definition will fail govalidator.ValidateStruct() (and the field values do not matter): +type exampleStruct struct { + Name string `` + Email string `valid:"email"` +} + +// this, however, will only fail when Email is empty or an invalid email address: +type exampleStruct2 struct { + Name string `valid:"-"` + Email string `valid:"email"` +} + +// lastly, this will only fail when Email is an invalid email address but not when it's empty: +type exampleStruct2 struct { + Name string `valid:"-"` + Email string `valid:"email,optional"` +} +``` + +#### Recent breaking changes (see [#123](https://github.com/asaskevich/govalidator/pull/123)) +##### Custom validator function signature +A context was added as the second parameter, for structs this is the object being validated – this makes dependent validation possible. +```go +import "github.com/asaskevich/govalidator" + +// old signature +func(i interface{}) bool + +// new

[#2](https://github.com/asaskevich/govalidator/pull/2) +If you want to validate structs, you can use tag `valid` for any field in your structure. All validators used with this field in one tag are separated by comma. If you want to skip validation, place `-` in your tag. If you need a validator that is not on the list below, you can add it like this: +```go +govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool { + return str == "duck" +}) +``` +For completely custom validators (interface-based), see below. + +Here is a list of available validators for struct fields (validator - used function): +```go +"email": IsEmail, +"url": IsURL, +"dialstring": IsDialString, +"requrl": IsRequestURL, +"requri": IsRequestURI, +"alpha": IsAlpha, +"utfletter": IsUTFLetter, +"alphanum": IsAlphanumeric, +"utfletternum": IsUTFLetterNumeric, +"numeric": IsNumeric, +"utfnumeric": IsUTFNumeric, +"utfdigit": IsUTFDigit, +"hexadecimal": IsHexadecimal, +"hexcolor": IsHexcolor, +"rgbcolor": IsRGBcolor, +"lowercase": IsLowerCase, +"uppercase": IsUpperCase, +"int": IsInt, +"float": IsFloat, +"null": IsNull, +"uuid": IsUUID, +"uuidv3": IsUUIDv3, +"uuidv4": IsUUIDv4, +"uuidv5": IsUUIDv5, +"creditcard": IsCreditCard, +"isbn10": IsISBN10, +"isbn13": IsISBN13, +"json": IsJSON, +"multibyte": IsMultibyte, +"ascii": IsASCII, +"printableascii": IsPrintableASCII, +"fullwidth": IsFullWidth, +"halfwidth": IsHalfWidth, +"variablewidth": IsVariableWidth, +"base64": IsBase64, +"datauri": IsDataURI, +"ip": IsIP, +"port": IsPort, +"ipv4": IsIPv4, +"ipv6": IsIPv6, +"dns": IsDNSName, +"host": IsHost, +"mac": IsMAC, +"latitude": IsLatitude, +"longitude": IsLongitude, +"ssn": IsSSN, +"semver": IsSemver, +"rfc3339": IsRFC3339, +"rfc3339WithoutZone": IsRFC3339WithoutZone, +"ISO3166Alpha2": IsISO3166Alpha2, +"ISO3166Alpha3": IsISO3166Alpha3, +``` +Validators with parameters + +```go +"range(min|max)": Range, +"length(min|max)": ByteLength, +"runelength(min|max)": RuneLength, +"stringlength(min|max)": StringLength, +"matches(pattern)": StringMatches, +"in(string1|string2|...|stringN)": IsIn, +"rsapub(keylength)" : IsRsaPub, +``` + +And here is small example of usage: +```go +type Post struct { + Title string `valid:"alphanum,required"` + Message string `valid:"duck,ascii"` + Message2 string `valid:"animal(dog)"` + AuthorIP string `valid:"ipv4"` + Date string `valid:"-"` +} +post := &Post{ + Title: "My Example Post", + Message: "duck", + Message2: "dog", + AuthorIP: "123.234.54.3", +} + +// Add your own struct validation tags +govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool { + return str == "duck" +}) + +// Add your own struct validation tags with parameter +govalidator.ParamTagMap["animal"] = govalidator.ParamValidator(func(str string, params ...string) bool { + species := params[0] + return str == species +}) +govalidator.ParamTagRegexMap["animal"] = regexp.MustCompile("^animal\\((\\w+)\\)$") + +result, err := govalidator.ValidateStruct(post) +if err != nil { + println("error: " + err.Error()) +} +println(result) +``` +###### WhiteList +```go +// Remove all characters from string ignoring characters between "a" and "z" +println(govalidator.WhiteList("a3a43a5a4a3a2a23a4a5a4a3a4", "a-z") == "aaaaaaaaaaaa") +``` + +###### Custom validation functions +Custom validation using your own domain specific validators is also available - here's an example of how to use it: +```go +import "github.com/asaskevich/govalidator" + +type CustomByteArray [6]byte // custom types are supported and can be validated + +type StructWithCustomByteArray struct { + ID CustomByteArray `valid:"customByteArrayValidator,customMinLengthValidator"` // multiple custom validators are possible as well and will be evaluated in sequence + Email string `valid:"email"` + CustomMinLength int `valid:"-"` +} + +govalidator.CustomTypeTagMap.Set("customByteArrayValidator", CustomTypeValidator(func(i interface{}, context interface{}) bool { + switch v := context.(type) { // you can type switch on the context interface being validated + case StructWithCustomByteArray: + // you can check and validate against some other field in the context, + // return early or not validate against the context at all – your choice + case SomeOtherType: + // ... + default: + // expecting some other type?

Unfortunately everything I've seen so far has a high chance of +breaking your application. + +The main problem is that a `http.ResponseWriter` often implements additional +interfaces such as `http.Flusher`, `http.CloseNotifier`, `http.Hijacker`, `http.Pusher`, and +`io.ReaderFrom`. So the naive approach of just wrapping `http.ResponseWriter` +in your own struct that also implements the `http.ResponseWriter` interface +will hide the additional interfaces mentioned above. This has a high change of +introducing subtle bugs into any non-trivial application. + +Another approach I've seen people take is to return a struct that implements +all of the interfaces above. However, that's also problematic, because it's +difficult to fake some of these interfaces behaviors when the underlying +`http.ResponseWriter` doesn't have an implementation. It's also dangerous, +because an application may choose to operate differently, merely because it +detects the presence of these additional interfaces. + +This package solves this problem by checking which additional interfaces a +`http.ResponseWriter` implements, returning a wrapped version implementing the +exact same set of interfaces. + +Additionally this package properly handles edge cases such as `WriteHeader` not +being called, or called more than once, as well as concurrent calls to +`http.ResponseWriter` methods, and even calls happening after the wrapped +`ServeHTTP` has already returned. + +Unfortunately this package is not perfect either. It's possible that it is +still missing some interfaces provided by the go core (let me know if you find +one), and it won't work for applications adding their own interfaces into the +mix. You can however use `httpsnoop.Unwrap(w)` to access the underlying +`http.ResponseWriter` and type-assert the result to its other interfaces. + +However, hopefully the explanation above has sufficiently scared you of rolling +your own solution to this problem. httpsnoop may still break your application, +but at least it tries to avoid it as much as possible. + +Anyway, the real problem here is that smuggling additional interfaces inside +`http.ResponseWriter` is a problematic design choice, but it probably goes as +deep as the Go language specification itself. But that's okay, I still prefer +Go over the alternatives ;). + +## Performance + +``` +BenchmarkBaseline-8 20000 94912 ns/op +BenchmarkCaptureMetrics-8 20000 95461 ns/op +``` + +As you can see, using `CaptureMetrics` on a vanilla http.Handler introduces an +overhead of ~500 ns per http request on my machine.

The following + types of operations are within the domain of template functions: + - Formatting + - Layout + - Simple type conversions + - Utilities that assist in handling common formatting and layout needs (e.g. arithmetic) +- Template functions should not return errors unless there is no way to print + a sensible value. For example, converting a string to an integer should not + produce an error if conversion fails. Instead, it should display a default + value. +- Simple math is necessary for grid layouts, pagers, and so on. Complex math + (anything other than arithmetic) should be done outside of templates. +- Template functions only deal with the data passed into them. They never retrieve + data from a source. +- Finally, do not override core Go template functions. diff --git a/vendor/github.com/go-task/slim-sprig/Taskfile.yml

With gob, you could just send it. With goprotobuf, you need to make a parallel struct. +Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions. + + - nullable, if false, a field is generated without a pointer (see warning below). + - embed, if true, the field is generated as an embedded field. + - customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128 + - customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames. + - casttype (beta), Changes the generated fieldtype. All generated code assumes that this type is castable to the protocol buffer field type. It does not work for structs or enums. + - castkey (beta), Changes the generated fieldtype for a map key. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps. + - castvalue (beta), Changes the generated fieldtype for a map value. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps. + +Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset. + +Let us look at: + + github.com/gogo/protobuf/test/example/example.proto + +for a quicker overview. + +The following message: + + package test; + + import "github.com/gogo/protobuf/gogoproto/gogo.proto"; + + message A { + optional string Description = 1 [(gogoproto.nullable) = false]; + optional int64 Number = 2 [(gogoproto.nullable) = false]; + optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false]; + } + +Will generate a go struct which looks a lot like this: + + type A struct { + Description string + Number int64 + Id github_com_gogo_protobuf_test_custom.Uuid + } + +You will see there are no pointers, since all fields are non-nullable. +You will also see a custom type which marshals to a string. +Be warned it is your responsibility to test your custom types thoroughly. +You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods. + +Next we will embed the message A in message B. + + message B { + optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true]; + repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false]; + } + +See below that A is embedded in B. + + type B struct { + A + G []github_com_gogo_protobuf_test_custom.Uint128 + } + +Also see the repeated custom type. + + type Uint128 [2]uint64 + +Next we will create a custom name for one of our fields. + + message C { + optional int64 size = 1 [(gogoproto.customname) = "MySize"]; + } + +See below that the field's name is MySize and not Size. + + type C struct { + MySize *int64 + } + +The is useful when having a protocol buffer message with a field name which conflicts with a generated method. +As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error. +Using customname you can fix this error without changing the field name. +This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable. + +Gogoprotobuf also has some more subtle changes, these could be changed back: + + - the generated package name for imports do not have the extra /filename.pb, + but are actually the imports specified in the .proto file. + +Gogoprotobuf also has lost some features which should be brought back with time: + + - Marshalling and unmarshalling with reflect and without the unsafe package, + this requires work in pointer_reflect.go + +Why does nullable break protocol buffer specifications: + +The protocol buffer specification states, somewhere, that you should be able to tell whether a +field is set or unset. With the option nullable=false this feature is lost, +since your non-nullable fields will always be set. It can be seen as a layer on top of +protocol buffers, where before and after marshalling all non-nullable fields are set +and they cannot be unset. + +Goprotobuf Compatibility: + +Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers. +Gogoprotobuf generates the same code as goprotobuf if no extensions are used. +The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf: + + - gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto. + - goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix + - goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method. + - goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face + - goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method. + - goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension + - goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields. + - goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf. This is necessary when using third-party packages which read registrations from golang/protobuf (such as the grpc-gateway). + +Less Typing and Peace of Mind is explained in their specific plugin folders godoc: + + - github.com/gogo/protobuf/plugin/ + +If you do not use any of these extension the code that is generated +will be the same as if goprotobuf has generated it. + +The most complete way to see examples is to look at + + github.com/gogo/protobuf/test/thetest.proto + +Gogoprototest is a seperate project, +because we want to keep gogoprotobuf independent of goprotobuf, +but we still want to test it thoroughly. + +*/ +package gogoproto diff --git a/vendor/github.com/gogo/protobuf/gogoproto/gogo.pb.go b/vendor/github.com/gogo/protobuf/gogoproto/gogo.pb.go new file mode 100644 index 0000000000..1e91766aee --- /dev/null +++ b/vendor/github.com/gogo/protobuf/gogoproto/gogo.pb.go @@ -0,0 +1,874 @@ +// Code generated by protoc-gen-gogo.

All client-side metrics start with `grpc_client`. Both of them have mirror-concepts. Similarly all methods +contain the same rich labels: + + * `grpc_service` - the [gRPC service](http://www.grpc.io/docs/#defining-a-service) name, which is the combination of protobuf `package` and + the `grpc_service` section name. E.g. for `package = mwitkow.testproto` and + `service TestService` the label will be `grpc_service="mwitkow.testproto.TestService"` + * `grpc_method` - the name of the method called on the gRPC service. E.g. + `grpc_method="Ping"` + * `grpc_type` - the gRPC [type of request](http://www.grpc.io/docs/guides/concepts.html#rpc-life-cycle). + Differentiating between the two is important especially for latency measurements. + + - `unary` is single request, single response RPC + - `client_stream` is a multi-request, single response RPC + - `server_stream` is a single request, multi-response RPC + - `bidi_stream` is a multi-request, multi-response RPC + + +Additionally for completed RPCs, the following labels are used: + + * `grpc_code` - the human-readable [gRPC status code](https://github.com/grpc/grpc-go/blob/master/codes/codes.go). + The list of all statuses is to long, but here are some common ones: + + - `OK` - means the RPC was successful + - `IllegalArgument` - RPC contained bad values + - `Internal` - server-side error not disclosed to the clients + +## Counters + +The counters and their up to date documentation is in [server_reporter.go](server_reporter.go) and [client_reporter.go](client_reporter.go) +the respective Prometheus handler (usually `/metrics`). + +For the purpose of this documentation we will only discuss `grpc_server` metrics. The `grpc_client` ones contain mirror concepts. + +For simplicity, let's assume we're tracking a single server-side RPC call of [`mwitkow.testproto.TestService`](examples/testproto/test.proto), +calling the method `PingList`. The call succeeds and returns 20 messages in the stream. + +First, immediately after the server receives the call it will increment the +`grpc_server_started_total` and start the handling time clock (if histograms are enabled). + +```jsoniq +grpc_server_started_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1 +``` + +Then the user logic gets invoked. It receives one message from the client containing the request +(it's a `server_stream`): + +```jsoniq +grpc_server_msg_received_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1 +``` + +The user logic may return an error, or send multiple messages back to the client. In this case, on +each of the 20 messages sent back, a counter will be incremented: + +```jsoniq +grpc_server_msg_sent_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 20 +``` + +After the call completes, its status (`OK` or other [gRPC status code](https://github.com/grpc/grpc-go/blob/master/codes/codes.go)) +and the relevant call labels increment the `grpc_server_handled_total` counter. + +```jsoniq +grpc_server_handled_total{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1 +``` + +## Histograms + +[Prometheus histograms](https://prometheus.io/docs/concepts/metric_types/#histogram) are a great way +to measure latency distributions of your RPCs. However, since it is bad practice to have metrics +of [high cardinality](https://prometheus.io/docs/practices/instrumentation/#do-not-overuse-labels) +the latency monitoring metrics are disabled by default. To enable them please call the following +in your server initialization code: + +```jsoniq +grpc_prometheus.EnableHandlingTimeHistogram() +``` + +After the call completes, its handling time will be recorded in a [Prometheus histogram](https://prometheus.io/docs/concepts/metric_types/#histogram) +variable `grpc_server_handling_seconds`. The histogram variable contains three sub-metrics: + + * `grpc_server_handling_seconds_count` - the count of all completed RPCs by status and method + * `grpc_server_handling_seconds_sum` - cumulative time of RPCs by status and method, useful for + calculating average handling times + * `grpc_server_handling_seconds_bucket` - contains the counts of RPCs by status and method in respective + handling-time buckets. These buckets can be used by Prometheus to estimate SLAs (see [here](https://prometheus.io/docs/practices/histograms/)) + +The counter values will look as follows: + +```jsoniq +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.005"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.01"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.025"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.05"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.1"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.25"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.5"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="1"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="2.5"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="5"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="10"} 1 +grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="+Inf"} 1 +grpc_server_handling_seconds_sum{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 0.0003866430000000001 +grpc_server_handling_seconds_count{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1 +``` + + +## Useful query examples + +Prometheus philosophy is to provide raw metrics to the monitoring system, and +let the aggregations be handled there. The verbosity of above metrics make it possible to have that +flexibility. Here's a couple of useful monitoring queries: + + +### request inbound rate +```jsoniq +sum(rate(grpc_server_started_total{job="foo"}[1m])) by (grpc_service) +``` +For `job="foo"` (common label to differentiate between Prometheus monitoring targets), calculate the +rate of requests per second (1 minute window) for each gRPC `grpc_service` that the job has. Please note +how the `grpc_method` is being omitted here: all methods of a given gRPC service will be summed together. + +### unary request error rate +```jsoniq +sum(rate(grpc_server_handled_total{job="foo",grpc_type="unary",grpc_code!="OK"}[1m])) by (grpc_service) +``` +For `job="foo"`, calculate the per-`grpc_service` rate of `unary` (1:1) RPCs that failed, i.e. the +ones that didn't finish with `OK` code. + +### unary request error percentage +```jsoniq +sum(rate(grpc_server_handled_total{job="foo",grpc_type="unary",grpc_code!="OK"}[1m])) by (grpc_service) + / +sum(rate(grpc_server_started_total{job="foo",grpc_type="unary"}[1m])) by (grpc_service) + * 100.0 +``` +For `job="foo"`, calculate the percentage of failed requests by service. It's easy to notice that +this is a combination of the two above examples. This is an example of a query you would like to +[alert on](https://prometheus.io/docs/alerting/rules/) in your system for SLA violations, e.g. +"no more than 1% requests should fail". + +### average response stream size +```jsoniq +sum(rate(grpc_server_msg_sent_total{job="foo",grpc_type="server_stream"}[10m])) by (grpc_service) + / +sum(rate(grpc_server_started_total{job="foo",grpc_type="server_stream"}[10m])) by (grpc_service) +``` +For `job="foo"` what is the `grpc_service`-wide `10m` average of messages returned for all ` +server_stream` RPCs. This allows you to track the stream sizes returned by your system, e.g. allows +you to track when clients started to send "wide" queries that ret +Note the divisor is the number of started RPCs, in order to account for in-flight requests. + +### 99%-tile latency of unary requests +```jsoniq +histogram_quantile(0.99, + sum(rate(grpc_server_handling_seconds_bucket{job="foo",grpc_type="unary"}[5m])) by (grpc_service,le) +) +``` +For `job="foo"`, returns an 99%-tile [quantile estimation](https://prometheus.io/docs/practices/histograms/#quantiles) +of the handling time of RPCs per service. Please note the `5m` rate, this means that the quantile +estimation will take samples in a rolling `5m` window. When combined with other quantiles +(e.g. 50%, 90%), this query gives you tremendous insight into the responsiveness of your system +(e.g. impact of caching). + +### percentage of slow unary queries (>250ms) +```jsoniq +100.0 - ( +sum(rate(grpc_server_handling_seconds_bucket{job="foo",grpc_type="unary",le="0.25"}[5m])) by (grpc_service) + / +sum(rate(grpc_server_handling_seconds_count{job="foo",grpc_type="unary"}[5m])) by (grpc_service) +) * 100.0 +``` +For `job="foo"` calculate the by-`grpc_service` fraction of slow requests that took longer than `0.25` +seconds. This query is relatively complex, since the Prometheus aggregations use `le` (less or equal) +buckets, meaning that counting "fast" requests fractions is easier. However, simple maths helps. +This is an example of a query you would like to alert on in your system for SLA violations, +e.g. "less than 1% of requests are slower than 250ms". + + +## Status + +This code has been used since August 2015 as the basis for monitoring of *production* gRPC micro services at [Improbable](https://improbable.io). + +## License + +`go-grpc-prometheus` is released under the Apache 2.0 license.

Check out the [documentation for all the details](https://onsi.github.io/ginkgo/#spec-timeouts-and-interruptible-nodes) but the gist is you can now write specs like this: + +```go +It("is interruptible", func(ctx SpecContext) { // or context.Context instead of SpecContext, both are valid. + // do things until `ctx.Done()` is closed, for example: + req, err := http.NewRequestWithContext(ctx, "POST", "/build-widgets", nil) + Expect(err).NotTo(HaveOccured()) + _, err := http.DefaultClient.Do(req) + Expect(err).NotTo(HaveOccured()) + + Eventually(client.WidgetCount).WithContext(ctx).Should(Equal(17)) +}, NodeTimeout(time.Second*20), GracePeriod(5*time.Second)) +``` + +and have Ginkgo ensure that the node completes before the timeout elapses. If it does elapse, or if an external interrupt is received (e.g. `^C`) then Ginkgo will cancel the context and wait for the Grace Period for the node to exit before proceeding with any cleanup nodes associated with the spec. The `ctx` provided by Ginkgo can also be passed down to Gomega's `Eventually` to have all assertions within the node governed by a single deadline. + +### Features + +- Ginkgo now records any additional failures that occur during the cleanup of a failed spec. In prior versions this information was quietly discarded, but the introduction of a more rigorous approach to timeouts and interruptions allows Ginkgo to better track subsequent failures. +- `SpecContext` also provides a mechanism for third-party libraries to provide additional information when a Progress Report is generated. Gomega uses this to provide the current state of an `Eventually().WithContext()` assertion when a Progress Report is requested. +- DescribeTable now exits with an error if it is not passed any Entries [a4c9865] + +## Fixes +- fixes crashes on newer Ruby 3 installations by upgrading github-pages gem dependency [92c88d5] +- Make the outline command able to use the DSL import [1be2427] + +## Maintenance +- chore(docs): delete no meaning d [57c373c] +- chore(docs): Fix hyperlinks [30526d5] +- chore(docs): fix code blocks without language settings [cf611c4] +- fix intra-doc link [b541bcb] + +## 2.2.0 + +### Generate real-time Progress Reports [f91377c] + +Ginkgo can now generate Progress Reports to point users at the current running line of code (including a preview of the actual source code) and a best guess at the most relevant subroutines. + +These Progress Reports allow users to debug stuck or slow tests without exiting the Ginkgo process. A Progress Report can be generated at any time by sending Ginkgo a `SIGINFO` (`^T` on MacOS/BSD) or `SIGUSR1`. + +In addition, the user can specify `--poll-progress-after` and `--poll-progress-interval` to have Ginkgo start periodically emitting progress reports if a given node takes too long. These can be overriden/set on a per-node basis with the `PollProgressAfter` and `PollProgressInterval` decorators. + +Progress Reports are emitted to stdout, and also stored in the machine-redable report formats that Ginkgo supports. + +Ginkgo also uses this progress reporting infrastructure under the hood when handling timeouts and interrupts. This yields much more focused, useful, and informative stack traces than previously. + +### Features +- `BeforeSuite`, `AfterSuite`, `SynchronizedBeforeSuite`, `SynchronizedAfterSuite`, and `ReportAfterSuite` now support (the relevant subset of) decorators. These can be passed in _after_ the callback functions that are usually passed into these nodes. + + As a result the **signature of these methods has changed** and now includes a trailing `args ...interface{}`. For most users simply using the DSL, this change is transparent. However if you were assigning one of these functions to a custom variable (or passing it around) then your code may need to change to reflect the new signature. + +### Maintenance +- Modernize the invocation of Ginkgo in github actions [0ffde58] +- Update reocmmended CI settings in docs [896bbb9] +- Speed up unnecessarily slow integration test [6d3a90e] + +## 2.1.6 + +### Fixes +- Add `SuppressProgressReporting` decorator to turn off --progress announcements for a given node [dfef62a] +- chore: remove duplicate word in comments [7373214] + +## 2.1.5 + +### Fixes +- drop -mod=mod instructions; fixes #1026 [6ad7138] +- Ensure `CurrentSpecReport` and `AddReportEntry` are thread-safe [817c09b] +- remove stale importmap gcflags flag test [3cd8b93] +- Always emit spec summary [5cf23e2] - even when only one spec has failed +- Fix ReportAfterSuite usage in docs [b1864ad] +- fixed typo (#997) [219cc00] +- TrimRight is not designed to trim Suffix [71ebb74] +- refactor: replace strings.Replace with strings.ReplaceAll (#978) [143d208] +- fix syntax in examples (#975) [b69554f] + +### Maintenance +- Bump github.com/onsi/gomega from 1.20.0 to 1.20.1 (#1027) [e5dfce4] +- Bump tzinfo from 1.2.9 to 1.2.10 in /docs (#1006) [7ae91c4] +- Bump github.com/onsi/gomega from 1.19.0 to 1.20.0 (#1005) [e87a85a] +- test: add new Go 1.19 to test matrix (#1014) [bbefe12] +- Bump golang.org/x/tools from 0.1.11 to 0.1.12 (#1012) [9327906] +- Bump golang.org/x/tools from 0.1.10 to 0.1.11 (#993) [f44af96] +- Bump nokogiri from 1.13.3 to 1.13.6 in /docs (#981) [ef336aa] + +## 2.1.4 + +### Fixes +- Numerous documentation typos +- Prepend `when` when using `When` (this behavior was in 1.x but unintentionally lost during the 2.0 rewrite) [efce903] +- improve error message when a parallel process fails to report back [a7bd1fe] +- guard against concurrent map writes in DeprecationTracker [0976569] +- Invoke reporting nodes during dry-run (fixes #956 and #935) [aae4480] +- Fix ginkgo import circle [f779385] + +## 2.1.3 + +See [https://onsi.github.io/ginkgo/MIGRATING_TO_V2](https://onsi.github.io/ginkgo/MIGRATING_TO_V2) for details on V2. + +### Fixes +- Calling By in a container node now emits a useful error.

It's easy to [bootstrap](https://onsi.github.io/ginkgo/#bootstrapping-a-suite) and start writing your [first specs](https://onsi.github.io/ginkgo/#adding-specs-to-a-suite). + +If you have a question, comment, bug report, feature request, etc. please open a [GitHub issue](https://github.com/onsi/ginkgo/issues/new), or visit the [Ginkgo Slack channel](https://app.slack.com/client/T029RQSE6/CQQ50BBNW). + +## Capabilities + +Whether writing basic unit specs, complex integration specs, or even performance specs - Ginkgo gives you an expressive Domain-Specific Language (DSL) that will be familiar to users coming from frameworks such as [Quick](https://github.com/Quick/Quick), [RSpec](https://rspec.info), [Jasmine](https://jasmine.github.io), and [Busted](https://lunarmodules.github.io/busted/). This style of testing is sometimes referred to as "Behavior-Driven Development" (BDD) though Ginkgo's utility extends beyond acceptance-level testing. + +With Ginkgo's DSL you can use nestable [`Describe`, `Context` and `When` container nodes](https://onsi.github.io/ginkgo/#organizing-specs-with-container-nodes) to help you organize your specs. [`BeforeEach` and `AfterEach` setup nodes](https://onsi.github.io/ginkgo/#extracting-common-setup-beforeeach) for setup and cleanup. [`It` and `Specify` subject nodes](https://onsi.github.io/ginkgo/#spec-subjects-it) that hold your assertions. [`BeforeSuite` and `AfterSuite` nodes](https://onsi.github.io/ginkgo/#suite-setup-and-cleanup-beforesuite-and-aftersuite) to prep for and cleanup after a suite... and [much more!](https://onsi.github.io/ginkgo/#writing-specs). + +At runtime, Ginkgo can run your specs in reproducibly [random order](https://onsi.github.io/ginkgo/#spec-randomization) and has sophisticated support for [spec parallelization](https://onsi.github.io/ginkgo/#spec-parallelization). In fact, running specs in parallel is as easy as + +```bash +ginkgo -p +``` + +By following [established patterns for writing parallel specs](https://onsi.github.io/ginkgo/#patterns-for-parallel-integration-specs) you can build even large, complex integration suites that parallelize cleanly and run performantly. And you don't have to worry about your spec suite hanging or leaving a mess behind - Ginkgo provides a per-node `context.Context` and the capability to interrupt the spec after a set period of time - and then clean up. + +As your suites grow Ginkgo helps you keep your specs organized with [labels](https://onsi.github.io/ginkgo/#spec-labels) and lets you easily run [subsets of specs](https://onsi.github.io/ginkgo/#filtering-specs), either [programmatically](https://onsi.github.io/ginkgo/#focused-specs) or on the [command line](https://onsi.github.io/ginkgo/#combining-filters). And Ginkgo's reporting infrastructure generates machine-readable output in a [variety of formats](https://onsi.github.io/ginkgo/#generating-machine-readable-reports) _and_ allows you to build your own [custom reporting infrastructure](https://onsi.github.io/ginkgo/#generating-reports-programmatically). + +Ginkgo ships with `ginkgo`, a [command line tool](https://onsi.github.io/ginkgo/#ginkgo-cli-overview) with support for generating, running, filtering, and profiling Ginkgo suites. You can even have Ginkgo automatically run your specs when it detects a change with `ginkgo watch`, enabling rapid feedback loops during test-driven development. + +And that's just Ginkgo! [Gomega](https://onsi.github.io/gomega/) brings a rich, mature, family of [assertions and matchers](https://onsi.github.io/gomega/#provided-matchers) to your suites. With Gomega you can easily mix [synchronous and asynchronous assertions](https://onsi.github.io/ginkgo/#patterns-for-asynchronous-testing) in your specs. You can even build your own set of expressive domain-specific matchers quickly and easily by composing Gomega's [existing building blocks](https://onsi.github.io/ginkgo/#building-custom-matchers). + +Happy Testing! + +## License + +Ginkgo is MIT-Licensed + +## Contributing + +See [CONTRIBUTING.md](CONTRIBUTING.md) diff --git a/vendor/github.com/onsi/ginkgo/v2/RELEASING.md b/vendor/github.com/onsi/ginkgo/v2/RELEASING.md new file mode 100644 index 0000000000..363815d7c7 --- /dev/null +++ b/vendor/github.com/onsi/ginkgo/v2/RELEASING.md @@ -0,0 +1,23 @@ +A Ginkgo release is a tagged git sha and a GitHub release.

This was accomplished by overriding the global fail handler when running the callbacks passed to `Eventually/Consistently` in order to capture any resulting errors. Issue #457 uncovered a flaw with this approach: when multiple `Eventually`s are running concurrently they race when overriding the singleton global fail handler. + +1.15.0 resolves this by requiring users who want to make assertions in `Eventually/Consistently` call backs to explicitly pass in a function that takes a `Gomega` as an argument. The passed-in `Gomega` instance can be used to make assertions. Any failures will cause `Eventually` to retry the callback. This cleaner interface avoids the issue of swapping out globals but comes at the cost of changing the contract introduced in v1.14.0. As such 1.15.0 introduces a breaking change with respect to 1.14.0 - however we expect that adoption of this feature in 1.14.0 remains limited. + +In addition, 1.15.0 cleans up some of Gomega's internals.

This allows + these functions to be used with the Succeed() matcher. + - Introduce InterceptGomegaFailure - an analogue to InterceptGomegaFailures - that captures the first assertion failure + and halts execution in its passed-in callback. + +### Fixes +- Call Verify GHTTPWithGomega receiver funcs (#454) [496e6fd] +- Build a binary with an expected name (#446) [7356360] + +## 1.13.0 + +### Features +- gmeasure provides BETA support for benchmarking (#447) [8f2dfbf] +- Set consistently and eventually defaults on init (#443) [12eb778] + +## 1.12.0 + +### Features +- Add Satisfy() matcher (#437) [c548f31] +- tweak truncation message [3360b8c] +- Add format.GomegaStringer (#427) [cc80b6f] +- Add Clear() method to gbytes.Buffer [c3c0920] + +### Fixes +- Fix error message in BeNumericallyMatcher (#432) [09c074a] +- Bump github.com/onsi/ginkgo from 1.12.1 to 1.16.2 (#442) [e5f6ea0] +- Bump github.com/golang/protobuf from 1.4.3 to 1.5.2 (#431) [adae3bf] +- Bump golang.org/x/net (#441) [3275b35] + +## 1.11.0 + +### Features +- feature: add index to gstruct element func (#419) [334e00d] +- feat(gexec) Add CompileTest functions.
