Tobias Guggenmos	408574a6e1	promql: Allow injecting fake tokens into the generated parser (#6381 ) * promql: Allow injecting fake tokens into the generated parser Yacc grammars do not support having multiple start symbols. To work around that restriction, it is possible to inject fake tokens into the lexer stream, as described here https://www.gnu.org/software/bison/manual/html_node/Multiple-start_002dsymbols.html . This is part of the parser rewrite effort described in #6256. Signed-off-by: Tobias Guggenmos <tguggenm@redhat.com>	5 years ago
Tobias Guggenmos	bbd92b85da	promql: Use capitalized names for item types (#6371 ) For yacc generated parsers there is the convention to capitalize the names of item types provided by the lexer, which makes it easy to distinct lexer tokens (capitalized) from nonterminal symbols (not capitalized) in language grammars. This convention is also followed by the (non generated) go compiler (see https://golang.org/pkg/go/token/#Token). Part of the parser rewrite described in #6256.

Tobias Guggenmos	c229ed17e2	promql: Implement yyLexer interface (#6370 ) This is the first step towards a generated lexer as described in #6256. It adds methods to the parser struct, that make it implement the yyLexer interface required by a yacc generated parser, as described here: https://godoc.org/golang.org/x/tools/cmd/goyacc . The yyLexer interface is implemented by the parser struct instead of the lexer struct for the following reasons: * Both parsers have a lookahead that the lexer does not know about. This solution makes it possible to synchronize these lookaheads when switching parsers. * The routines to handle parser errors are not accessible to the lexer.

Tobias Guggenmos	c63259b83c	promql: Clean up parser struct (#6360 ) * promql: Clean up parser struct The parser struct used two have two somewhat misused fields: peekCount int token [3]item By reading the code carefully one notices, that peekCount always has the value 0 or 1 and that only the first element of token is ever accessed. To make this clearer, this commit replaces the token array with a single variable and the peekCount int with a boolean. Signed-off-by: Tobias Guggenmos <tguggenm@redhat.com>	5 years ago

Tobias Guggenmos	ac3932ea35	Improve PromQL parser performance by making it non-concurrent (#6356 ) Before this commit, the PromQL parser ran in two goroutines: * The lexer goroutine that splits the input into tokens and sent them over a channel to * the parser goroutine which produces the abstract syntax tree The Problem with this approach is that the parser spends more time on goroutine creation and syncronisation than on actual parsing. This commit removes that concurrency and replaces the channel by a slice based buffer. Benchmarks show that this makes the up to 7 times faster than before.

Advait Bhatwadekar	5d401f1e1b	Added query logging for prometheus. Issue #1315 (#5794 ) * Added query logging for prometheus. Options added: 1) active.queries.filepath: Filename where queries will be recorded 2) active.queries.filesize: Size of the file where queries will be recorded. Functionality added: All active queries are now logged in a file. If prometheus crashes unexpectedly, these queries are also printed out on stdout in the rerun. Queries are written concurrently to an mmaped file, and removed once they are done. Their positions in the file are reused. They are written in json format. However, due to dynamic nature of application, the json has an extra comma after the last query, and is missing an ending ']'. There may also null bytes in the tail of file.

Julius Volz	8155cc4992	Expose lexer item types (#5358 ) * Expose lexer item types We have generally agreed to expose AST types / values that are necessary to make sense of the AST outside of the promql package. Currently the `UnaryExpr`, `BinaryExpr`, and `AggregateExpr` AST nodes store the lexer item type to indicate the operator type, but since the individual item types aren't exposed, an external user of the package cannot determine the operator type. So this PR exposes them. Although not all item types are required to make sense of the AST (some are really only used in the lexer), I decided to expose them all here to be somewhat more consistent. Another option would be to not use lexer item types at all in AST nodes. The concrete motivation is my work on the PromQL->Flux transpiler, but this ought to be useful for other cases as well.
