Overall, wildcards create ambiguity that +requires us to consider different query interpretations. + +There are four query interpretations for the example (`*task* took 0.3*`): + +1. Interpretation 1: + * Dictionary variable queries: `["*task*"]` + * Encoded variable queries: `["0.3*"]` + * Logtype query: `** took *` +2. Interpretation 2: + * Dictionary variables queries: `["*task*", "0.3*"]` + * Encoded variable queries: `[]` + * Logtype query: `** took *` +3. Interpretation 3: + * Dictionary variable queries: `[]` + * Encoded variable queries: `["0.3*"]` + * Logtype query: `*task* took *` +4. Interpretation 4: + * Dictionary variable queries: `["0.3*"]` + * Encoded variable queries: `[]` + * Logtype query: `*task* took *` + +We call each of these interpretations a subquery. A message which matches any +subquery matches the original wildcard query (with one exception mentioned +later). In other words, the subqueries form a logical disjunction (i.e., the +subqueries are OR-ed together to comprise the original query). The rest of this +doc explains how we generate these subqueries. For more background on logtypes, +variables, etc., see the +[CLP paper](https://www.usenix.org/system/files/osdi21-rodrigues.pdf). + +## Handling ambiguity + +To parse a query, we need to consider two sources of ambiguity: + +* How each interpretation of a wildcard changes the tokenization. +* What variable patterns match a wildcard-containing token, and the variable + placeholders each matching pattern uses. + +We consider each source of ambiguity below. + +### Tokenization with wildcards + +Consider `*task?123*` and assume we use the default variable patterns. + +* If the `?` matches a non-delimiter, this query could match a single dictionary + variable, e.g., `task_123`. +* If the `?` matches a delimiter (e.g., `:`), this query could match a message + with some static text `task:` and an encoded variable `123`. + +Thus, for every wildcard we need to consider each possibility +(delimiter/non-delimiter). For `?`, this is simple as shown in the example. +However, `*` is more involved since it can match zero or more characters---in +other words, a single `*` could match both delimiters and non-delimiters. + +#### Handling `*` + +Consider how we might tokenize `*to*container* 0.335 *`. `*to*container*` +could be one or more tokens depending on how we interpret each `*`. `0.335` is +a token that can be encoded as a float variable. The lone `*` can match any +number of tokens. + +For `*to*container*`, Table 1 below lists the *spans* we can generate based on +how we interpret each `*`. We use the term *span* to refer to either a +contiguous set of non-delimiters (i.e., tokens) or a contiguous set of +delimiters. + +| \# | `*` interpretation | Spans | +|-----|---------------------|--------------------------------------| +| 1 | Delimiters only | `*`, `to`, `*`, `container`, `*` | +| 2 | Non-delimiters only | `*to*container*` | +| 3 | Both | `*`, `*to*`, `*`, `*container*`, `*` | + +*Table 1: The spans generated by tokenizing `*to*container*` depending on the +interpretation of `*`s.* + +To understand the spans generated by the third interpretation, consider the +central `*` and surrounding non-wildcards in the original query. Since the `*` +is interpreted as containing both non-delimiters and delimiters, then there must +be at least one delimiter between `to` and `container`. Table 2 below lists a +set of substrings that could match `to*container`. + +| Substring | Parts matched by the `*` | +|------------------------|--------------------------------------------------------------------------------| +| `to:::container` | Delimiters (`:::`) | +| `tools:container` | Non-delimiters (`ols`) followed by a delimiter (`:`) | +| `tools:new:mcontainer` | Non-delimiters, a delimiter, non-delimiters, a delimiter, and a non-delimiter. | + +*Table 2: Some substrings that can be matched by `container*to` where the +central `*` is interpreted as matching a combination of non-delimiters and +delimiters.* + +From the table, we can see that the central `*` could match the following in +sequence: + +* zero or more non-delimiters attached to `to`, followed by +* at least one delimiter or a combination of non-delimiters and delimiters, and + finally +* zero or more non-delimiters before `container`. + +Thus, we can break the central `*` into three `*` corresponding to each case of +the sequence: one as a suffix of `to`, a lone `*`, and one as a prefix of +`container`. + +Comparing the first and third interpretation in Table 1, we can see that the +third is a more general version of the first. As a result, we don't need to +consider the first interpretation. We can generalize this as follows: + +> If a `*` is interpreted to have a different type than either of the +> characters surrounding it, the tokenization should split the string at the +> `*` while leaving a `*` attached to the surrounding characters. + +So the wildcard-containing token, `*container*to*`, can be tokenized either as: + +1. `*container*` and `*to*`, or +2. `*container*to*` + +Note that we don't need to consider the lone `*` as a potential variable since +it matches *all* variable patterns; similarly, we don't need to consider what +variable placeholders it needs in the logtype since it matches *all* variable +placeholders. A consequence of this is that the interpretation of a +wildcard-containing token's boundary `*` wildcards (wildcards at the beginning +or end of a token) does not affect how we tokenize a wildcard-containing token. +In other words, we don't need to consider the non-delimiters-only case for `*` +boundary wildcards. + +## Matching variable patterns to wildcard-containing tokens + +The precise mechanism for matching a variable pattern against a +wildcard-containing token is an implementation detail, but it is worth +considering the difference between matching a token in a log message versus +matching a wildcard-containing token in a wildcard query. + +In a log message, if two or more patterns match a token, we apply the pattern +that appears first in the schema file. However, when two or more patterns match +a wildcard-containing token, we can't choose the first pattern unless it is a +superset of the other patterns; this really means the other patterns would never +apply since any token matching the first pattern would match the other patterns +as well, so the other patterns would never be applied. (In the future, we will +likely warn users when their patterns have this property.) So if two or more +non-nested (i.e., one is not a superset of the other) patterns match, we can't +choose the first pattern since that would ignore cases where only the second +pattern's variables match the query. For instance, consider these non-nested +patterns: + +``` +ip_addr: \d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3} +float: \d+\.\d+ +``` + +If we encounter a wildcard-containing token like `*1.2*`, we have to search for +variables matching either `ip_addr` or `float`. For instance, encoded messages +might contain a message with the `float`, `1.23` and/or they might contain a +message with the `ip_addr`, `1.2.3.4`. Since the two variables use different +placeholders in the logtype, we need to generate a separate subquery for each. + +## Generating Subqueries + +Based on the analysis above, we can develop an algorithm to generate all +possible subqueries. One approach is to iterate through each possible +interpretation of every wildcard. For a given interpretation, we would tokenize +the query, and for each wildcard-containing token, we would iterate through its +matching variable patterns. The approach we take is a slight variation of this. + +At a high-level, the algorithm is as follows: + +First, we tokenize the query, treating every (unescaped) wildcard as a +non-delimiter. At this point, if we were to remove all wildcard-containing +tokens, then we would have no wildcards remaining in the query. This is helpful +because it allows us to leave the part of the query *without* wildcards intact +while we iterate on every interpretation of the wildcard-containing tokens. + +When constructing a wildcard-containing token, we find each wildcard and +determine whether they could be interpreted as matching only non-delimiters or +only delimiters, or both. + +When constructing a wildcard-containing token, we also tokenize it based on the +current interpretation of wildcards. This may lead to creating a token that's +static text, a token that's a variable, and/or a smaller +wildcard-containing token. For example, if we were to tokenize the +wildcard-containing token `?abc?123?`, interpreting every `?` as matching a +delimiter, then we would end up with two tokens, `abc` and `123`. `abc` is +static text while `123` is an integer variable. Now if the central `?` was +interpreted as matching a non-delimiter, then the only token generated would be +`abc?123` which can only match a dictionary variable. + +As a result, we call the original wildcard-containing token a +`CompositeWildcardToken`, since it can generate multiple smaller tokens based on +the interpretation of its wildcards. We call each smaller wildcard-containing +token a `WildcardToken` since it is not further divisible. Finally, we call +each token that doesn't contain a wildcard and which matches a variable pattern, +an `ExactVariableToken`, in contrast with a `WildcardToken`. + +When constructing a `WildcardToken`, we find all the variable patterns that it +can match as well as if it can match static text. Each case is an interpretation +we must consider when generating subqueries. + +Once tokenization is complete, we will already have an interpretation of +wildcards and `WildcardToken`s from which we can generate a subquery. So the +next step is to generate a subquery and then begin iterating. + +The first layer of iteration is the interpretation of each `WildcardToken`s. +Essentially, we change the interpretation of a single `WildcardToken` and then +generate another subquery. We repeat this process until the chosen +`WildcardToken` has no new interpretations at which point we reset its +interpretation and advance the interpretation of the next `WildcardToken`. +This process continues much like a counter (e.g., 00, 01, 10, 11) where when a +bit overflows, we increment the next highest bit and then continue counting +from the bit place. + +When we've exhausted all `WildcardToken`s, the second layer of iteration is the +interpretation of each wildcard. + +When every iteration is complete, we will have a complete list of subqueries. +However, some subqueries may be duplicates of each other. For instance, consider +`*abc*def?`. When all wildcards are interpreted to match delimiters, one +subquery we would generate is: + +* Dictionary variable queries: `[]` +* Encoded variable queries: `[]` +* Logtype query: `*abc*def?` + +where both `*abc*` and `*def?` are interpreted as static text. Similarly, when +the `?` is interpreted to match non-delimiters, we could again generate the same +subquery. Therefore, we deduplicate the subqueries during generation. + +One final nuance of using the subqueries as described is that if a message +matches a subquery, it does not guarantee that the message matches the original +wildcard query. Consider Interpretation 1 from the motivating example: + +1. Interpretation 1: + * Dictionary variable queries: `["*task*"]` + * Encoded variable queries: `["0.3*"]` + * Logtype query: `* took *` + +And consider this encoded message: + +* Dictionary variables: `["task_12"]` +* Encoded variables: `[0.4, 0.3]` +* Logtype: ` took above ` + +We can see that this encoded message matches the subquery, but when decoded, +it is `"task_12 took 0.4 above 0.3"` which does not match the original wildcard +query `*task* took 0.3*`. This is because the subqueries as described don't +consider the position of query variables in relation to the logtype query. +A bruteforce solution is simply to decode messages which match the subqueries +and then perform a wildcard match with the original query. However, more +efficient approaches do exist and can be implemented when necessary. diff --git a/components/core/src/glt/ffi/search/Subquery.cpp b/components/core/src/glt/ffi/search/Subquery.cpp new file mode 100644 index 000000000..37e0c0ac2 --- /dev/null +++ b/components/core/src/glt/ffi/search/Subquery.cpp @@ -0,0 +1,62 @@ +#include "Subquery.hpp" + +#include "../../ir/parsing.hpp" +#include "../../ir/types.hpp" +#include "QueryWildcard.hpp" + +using std::string; +using std::variant; +using std::vector; + +namespace clp::ffi::search { +template +Subquery::Subquery(string logtype_query, Subquery::QueryVariables variables) + : m_logtype_query{std::move(logtype_query)}, + m_logtype_query_contains_wildcards{false}, + m_query_vars{std::move(variables)} { + // Determine if the query contains wildcards and record the positions of the variable + // placeholders. + bool is_escaped{false}; + auto const logtype_query_length{m_logtype_query.size()}; + std::vector escaped_placeholder_positions; + escaped_placeholder_positions.reserve(logtype_query_length / 2); + auto const escape_char{enum_to_underlying_type(ir::VariablePlaceholder::Escape)}; + for (size_t idx = 0; idx < logtype_query_length; ++idx) { + char const c{m_logtype_query[idx]}; + if (is_escaped) { + is_escaped = false; + if (ir::is_variable_placeholder(c)) { + escaped_placeholder_positions.push_back(idx); + } + } else if (escape_char == c) { + is_escaped = true; + } else if ((enum_to_underlying_type(WildcardType::ZeroOrMoreChars) == c + || enum_to_underlying_type(WildcardType::AnyChar) == c)) + { + m_logtype_query_contains_wildcards = true; + } + } + if (false == m_logtype_query_contains_wildcards || escaped_placeholder_positions.empty()) { + return; + } + + // Query contains wildcards and variable placeholders, so we need to add an additional escape + // for each variable placeholder. + std::string double_escaped_logtype_query; + size_t pos{0}; + for (auto const placeholder_pos : escaped_placeholder_positions) { + double_escaped_logtype_query.append(m_logtype_query, pos, placeholder_pos - pos); + double_escaped_logtype_query += escape_char; + pos = placeholder_pos; + } + if (logtype_query_length != pos) { + double_escaped_logtype_query.append(m_logtype_query, pos); + } + m_logtype_query = std::move(double_escaped_logtype_query); +} + +// Explicitly declare specializations to avoid having to validate that the template parameters are +// supported +template class Subquery; +template class Subquery; +} // namespace clp::ffi::search diff --git a/components/core/src/glt/ffi/search/Subquery.hpp b/components/core/src/glt/ffi/search/Subquery.hpp new file mode 100644 index 000000000..33863d459 --- /dev/null +++ b/components/core/src/glt/ffi/search/Subquery.hpp @@ -0,0 +1,53 @@ +#ifndef CLP_FFI_SEARCH_SUBQUERY_HPP +#define CLP_FFI_SEARCH_SUBQUERY_HPP + +#include +#include +#include + +#include "ExactVariableToken.hpp" +#include "WildcardToken.hpp" + +namespace clp::ffi::search { +/** + * A class representing a subquery.
