promql: Add 'bool' modifier to comparison functions When doing comparison operations on vectors, filtering sometimes gets in the way and you have to go to a fair bit of effort to workaround it in order to always return a result. The 'bool' modifier instead of filtering returns 0/1 depending on the result of the compairson. This is also a prerequisite to removing plain scalar/scalar comparisons, as it maintains the current behaviour under a new syntax.

promql: Remove scalar/scalar comparisons. This change is breaking, use the 'bool' modifier for such comprisons. After this change all comparisons without 'bool' will filter, and all comparisons with 'bool' will return 0/1. This makes the language more consistent and orthogonal, and ultimately easier to learn and use. If we ever figure out sane semantics for filtering scalar/scalar comparisons we can add them in, which will most likely come out of how the new vector() function is used.

promql: Add 'bool' modifier to comparison functions When doing comparison operations on vectors, filtering sometimes gets in the way and you have to go to a fair bit of effort to workaround it in order to always return a result. The 'bool' modifier instead of filtering returns 0/1 depending on the result of the compairson. This is also a prerequisite to removing plain scalar/scalar comparisons, as it maintains the current behaviour under a new syntax.

Add without aggregator modifier. This has the advantage that the user doesn't need to list all labels they want to keep (as with "by") but without having to worry about inconsistent labels as when there's only one time series (as with "keeping_common"). Almost all aggregation should use this rather than the existing two options as it's much less error prone and easier to maintain due to not having to always add in "job" plus whatever other common job-level labels you have like "region".

Fix parsing of label names which are also keywords The current separation between lexer and parser is a bit fuzzy when it comes to operators, aggregators and other keywords. The lexer already tries to determine the type of a token, even though that type might change depending on the context. This led to the problematic behavior that no tokens known to the lexer could be used as label names, including operators (and, by, ...), aggregators (count, quantile, ...) or other keywords (for, offset, ...). This change additionally checks whether an identifier is one of these types. We might want to check whether the specific item identification should be moved from the lexer to the parser.

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.

Almost all aggregation should use this rather than the existing two options as it's much less error prone and easier to maintain due to not having to always add in "job" plus whatever other common job-level labels you have like "region".

PromQL: Fix panic in parser (#6650) Fixes #6649. The crash is fixed here, was caused because some AST sanity checks were performed on the syntax tree while assembling it. In case of previous parsing errors this could lead to undefined behaviour. The fix is to move the checks to the typechecking phase, which runs only when a syntax tree was assembled without there being parsing errors. There are other places, where similiar checks are performed while assembling the syntax tree. It might be a good idea to move those to the typechecking phase, too. Should I do this in the same or a separate PR? Signed-off-by: Tobias Guggenmos <tguggenm@redhat.com>

Support escape sequences in strings and add raw strings. This adapts some functionality from the Go standard library for string literal lexing and unquoting/unescaping. The following string types are now supported: Double- or single-quoted strings: These support all escape sequences that Go supports in double-quoted string literals. The difference is that Prometheus also has single-quoted strings (instead of single-quoted runes in Go). Raw newlines are not allowed. Backtick-quoted raw strings: Strings quoted in backticks are treated as raw strings just like in Go and may contain raw newlines and other special characters directly.
