: Addition offutures
andhumantime
dependencies, and a new binarystore-api
.The addition of
futures
andhumantime
dependencies aligns with the need for asynchronous and time-related functionalities in fuzz tests. The declaration ofstore-api
as a workspace member ensures that it is correctly integrated into the project's build process.Ensure that these dependencies are used appropriately in the project to avoid unnecessary bloat.

: Change oftable_name
field type fromString
toIdent
.This change enhances type safety and consistency across the codebase. Using
Ident
instead ofString
for SQL identifiers is a good practice as it can provide additional type checks and potentially reduce errors during compile time.tests-fuzz/src/utils.rs (2)

: Addition of new constants for cluster configurationThe constants
GT_FUZZ_CLUSTER_NAMESPACE
andGT_FUZZ_CLUSTER_NAME
are added to configure cluster settings. This is a good practice as it avoids hardcoding values and makes the configuration more flexible. Ensure these constants are used consistently throughout the codebase.Verification successful
Consistent usage of new constants

: Implementation offlush_memtable
functionThe
flush_memtable
function is crucial for ensuring data consistency during tests by flushing the memtable to an SST file. The implementation uses dynamic SQL construction, which can be prone to errors if not handled correctly. Ensure that thesql
variable is properly sanitized and tested to prevent SQL injection vulnerabilities.tests-fuzz/src/generator/insert_expr.rs (1)
106-106
: Optimization inInsertIntoExpr
generatorThe change from
.to_string()
to.clone()
for thetable_name
assignment is a good optimization. It avoids unnecessary string creation and leverages theClone
trait, which is more efficient forIdent
types that might already be stored in memory.Makefile (1)
173-176
: Addition offuzz-ls
target in MakefileThe new
fuzz-ls
target is a useful addition for listing all available fuzz targets. This enhances the usability of the fuzz testing framework by providing a quick way to view all targets. Ensure that this target is documented in the Makefile to help new developers understand its purpose.tests-fuzz/src/ir.rs (2)

: Add comments toregion_distribution
The function
region_distribution
could benefit from additional comments explaining its role in mapping partitions to datanodes, which would improve code maintainability.+ // Maps each partition to its corresponding datanode and aggregates the regions under each datanode. fn region_distribution(partitions: Vec<Partition>) -> BTreeMap<u64, Vec<RegionId>> {
315-319
: Approve logging inpretty_print_region_distribution
The
pretty_print_region_distribution
function uses structured logging effectively to display the distribution of regions across datanodes. This is a good practice in maintaining clarity in log outputs.
287-301
: Improve error handling incollect_table_partitions
The function
collect_table_partitions
uses.unwrap()
which could potentially lead to panics. Replace with proper error handling to make the function more robust.- let table_partitions = fetch_partitions(&ctx.greptime, table_ctx.name.clone()).await.unwrap(); + let table_partitions = fetch_partitions(&ctx.greptime, table_ctx.name.clone()).await.context(error::FetchPartitionsSnafu { table_name: &table_ctx.name })?;Likely invalid or redundant comment.
103-137
: Review the use of random generators in critical pathThe function
generate_create_exprs
uses random generators for table names and other parameters. While this is typical in fuzz testing, ensure that the randomness does not introduce flakiness in tests where deterministic outcomes are necessary.Verification successful
Verified: Randomness in
generate_create_exprs
is controlledThe function
generate_create_exprs
is used within thetests-fuzz/targets/failover/fuzz_failover_mito_regions.rs
file, which includes RNG seeding. This indicates that the randomness is controlled and should not introduce flakiness in tests.
- The RNG seeding is present in multiple test files, ensuring controlled randomness.
- The specific test file using
generate_create_exprs
also includes RNG seeding.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify that the random generation logic does not introduce flakiness. # Test: Run the generate_create_exprs function multiple times and ensure consistent outcomes where necessary. echo "Manual verification required: Run the generate_create_exprs function multiple times to check for consistency."Length of output: 228

: Efficient and robust database interaction.The function
fetch_nodes
usessqlx
to asynchronously fetch node information from a database. The use of.context

: Review offetch_partitions
: Ensure proper handling of Ident typeThe function
fetch_partitions
correctly uses parameterized queries which is good for security. However, the.bind
method is called withtable_name.value.to_string()
, which might not be the most efficient way ifIdent
can be directly bound as a parameter. IfIdent
implements traits to support direct binding, consider using it directly.Verification successful
Conclusion:
Ident
cannot be directly used with sqlx bindThe
Ident
type intests-fuzz/src/ir.rs
does not implement traits required for direct binding with sqlx (such asEncode
orType
). Therefore, the current use oftable_name.value.to_string()
in the.bind
method is appropriate.

: Refactor error handling inexecute_insert_exprs
The function
execute_insert_exprs

: Review changes toCreateTableExprGenerator
The change from
String
toIdent
for thename
field inCreateTableExprGenerator
is a significant modification. This change aligns with the overall goal of improving type safety and clarity in table name handling. The use of theIdent
type ensures that the table names are handled more consistently and can support more complex naming conventions including those requiring quoting or escaping.Ensure that all usages of this generator have been updated to handle the
Ident
type appropriately. This includes checking that any serialization or deserialization code, logging, or error handling that might rely on the table name being a simple string is updated to handle theIdent
type.Additionally, review related functions and methods to ensure they do not perform unnecessary conversions or checks that might be handled by the
Ident
type itself..github/workflows/develop.yml (1)

: Review of the New Distributed Fuzz Test with Chaos Job
Job Setup and Dependencies:
- The job correctly specifies
runs-on: ubuntu-latest
and depends onbuild-greptime-ci
. This setup ensures that the job runs on a fresh virtual environment and only starts after the necessary build job completes.Strategy Matrix:
- The matrix setup for
target
andmode
is well-defined, focusing on a specific fuzz target and environment setup. This allows for targeted testing under specific conditions, which is excellent for isolating and reproducing issues.Service Setup:
- The steps to set up Kind, Chaos Mesh, Minio, and Kafka are well-organized. However, using
.github/actions/setup-kind
and similar custom actions for setup tasks is crucial to maintain as updates to these actions can directly affect the workflow's reliability and performance.Environment Configuration:
- The use of environment variables like
CUSTOM_LIBFUZZER_PATH
andGT_MYSQL_ADDR
is appropriate. These are essential for configuring the fuzz test environment correctly.Resource Cleanup:
- The steps to delete the cluster and clean up Docker resources are crucial to prevent resource leakage. This is particularly important in CI environments where resources are limited.
Potential Improvements:
- Consider parameterizing the
ubuntu-latest
runner to use a specific version for more consistent results across runs.- The cleanup commands could be placed in a separate job that always runs regardless of success or failure to ensure cleanup happens even if the job is canceled or fails unexpectedly.
Overall, the job setup looks robust with a focus on detailed testing and environment isolation, which is crucial for fuzz testing.

: Refactor error handling inexecute_insert_exprs
The function
execute_insert_exprs
uses.unwrap()
within an async block, which could lead to panics if errors occur. Refactor to use proper error handling and potentially return detailed error information to the caller.- let _permit = semaphore.acquire().await.unwrap(); - let sql = translator.translate(&insert_expr)?; + let _permit = semaphore.acquire().await?; + let sql = translator.translate(&insert_expr).context(error::TranslateQuerySnafu { expr: &insert_expr })?;
358-375
: Ensure robust error handling inwait_condition_fn
The
wait_condition_fn
uses unwrapping in several places, which could lead to panics if unexpected conditions occur. Enhance error handling to make the function more resilient and less prone to crashes.- let partition = count_partitions(&greptime, selected_datanode).await.unwrap(); + let partition = count_partitions(&greptime, selected_datanode).await.context(error::CountPartitionsSnafu { datanode_id: selected_datanode })?;
434-450
: Improve error messages in fuzzing entry pointThe main fuzzing entry point could benefit from more descriptive error messages, especially when initialization fails. This would help in debugging and maintaining the code.
- mysql.expect("mysql connection init must be succeed"), - kube::client::Client::try_default().await.expect("init kube client"), + mysql.context(error::InitDbConnectionSnafu)?, + kube::client::Client::try_default().await.context(error::InitKubeClientSnafu)?,

: Addition of new modules and constantsThe addition of
cluster_info
,config
,crd
,health
,partition
, andwait
modules expands the utility functions available for fuzz testing. Ensure these modules are properly documented and tested, especially since they seem to interact with potentially complex functionalities like cluster management and partition handling.
93-94
: Introduction of new constants for cluster configurationThe introduction of
GT_FUZZ_CLUSTER_NAMESPACE
andGT_FUZZ_CLUSTER_NAME
constants is a positive change as it standardizes the configuration and makes the codebase more maintainable. It's essential to ensure that these constants are used consistently across the codebase.

: Improve Error Handling in Environment Variable LoadingThe use of
expect
inload_unstable_test_env_variables
can lead to panics if the environment variables are not set, which is not ideal for production code. Consider using more graceful error handling to improve the robustness of the code.- let binary_path = env::var(GT_FUZZ_BINARY_PATH).expect("GT_FUZZ_BINARY_PATH not found"); + let binary_path = env::var(GT_FUZZ_BINARY_PATH).unwrap_or_else(|_| "default_binary_path".to_string());

: Secure and Optimize Database Operation FunctionsThe functions
flush_memtable
andcompact_table
use dynamic SQL generation, which can be susceptible to SQL injection if not handled correctly. Ensure that inputs liketable_name
are properly sanitized before use in SQL queries. Additionally, consider using parameterized queries to enhance security and performance.- let sql = format!("SELECT flush_table(\"{}\")", table_name); + let sql = "SELECT flush_table(?)"; - let result = sqlx::query(&sql).execute(e).await.context(error::ExecuteQuerySnafu { sql })?; + let result = sqlx::query(sql).bind(table_name).execute(e).await.context(error::ExecuteQuerySnafu { sql })?;
[!TIP]
Codebase VerificationEnsure Robust Error Handling in Database Connection Setup
The functions
init_greptime_connections_via_env
andinit_greptime_connections
intests-fuzz/src/utils.rs
useunwrap()
for error handling, which can cause the program to panic if an error occurs. This is not recommended for robust error handling, especially in production code.
- Line 63:
let mut opts: MySqlConnectOptions = format!("mysql://{addr}/public").parse().unwrap();
- Line 64:
Some(MySqlPoolOptions::new().connect_with(opts).await.unwrap())
Consider replacing
unwrap()
with proper error handling to ensure the program can handle errors gracefully.Analysis chain
