agent failed to finish the full-history scan: trufflehog timed out with

Not specified by the original author.

TL;DR

Full history is unbounded work. Bound it with commit ranges, stream findings as they come instead of buffering, and let the agent resume from the last completed commit.

Error

agent failed to finish the full-history scan: trufflehog timed out with error

Steps

1. Split history into commit ranges the agent processes sequentially. Expected: each range fits the budget.
2. Stream JSON findings per commit instead of collecting everything in memory. Expected: constant memory use.
3. Record the last completed commit as a resume cursor. Expected: timeouts resume, not restart.
4. Skip or sample binary-heavy ranges that slow detectors disproportionately. Expected: the long tail shrinks.
5. Reassemble the streamed findings into the final report. Expected: complete history covered.

When to use

• Agent trufflehog scans timing out on long histories.
• Building resumable scan agents.

When not to use

• Authentication failures.
• The scan errors on a specific commit (investigate it).

Tool compatibility

• Trufflehog git scans; JSON streaming; resume cursors.

Variant phrasings

trufflehog full history timeout

Range and resume.

agent scan of git history never finishes

Same bounding.

Why it happens

History length times detector cost exceeds any single run budget; without cursors, each timeout restarts from zero.

Edge cases

• Rewritten history invalidates cursors; detect and restart cleanly.
• Shallow or partial clones change what history exists; document the clone flags.
• Findings order is not stable across runs; dedup by finding id.

Thread query: agent failed to finish the full-history scan: trufflehog timed out with error

TL;DR: Full history is unbounded work. Bound it with commit ranges, stream findings as they come instead of buffering, and let the agent resume from the last completed commit.

Not specified by the original author.

TL;DR

The scan hit its time budget before finishing, which is normal on large histories. Give it more time, narrow the scope to what changed, or split the history into chunks. The timeout is a guardrail, not a bug.

Error

"trufflehog: context deadline exceeded" scanning repo

Steps

1. Estimate the repo size (commits, total objects) to confirm scale is the cause. Expected: a large history, not a hung process.
2. Raise the timeout flag for the run. Expected: the scan gets further or completes.
3. Narrow the scope: scan only recent history or specific branches instead of everything. Expected: the bounded scan completes quickly.
4. For full-history needs, chunk by commit range and run sequentially. Expected: each chunk fits in the budget.
5. Record the working scope and timeout in the scan job so it stays reproducible. Expected: future runs do not regress.

When to use

• Trufflehog times out on big repos.
• You need a full-history scan but cannot finish in one run.

When not to use

• Authentication failures (fix creds, not timeouts).
• The scan hangs on one commit (investigate that commit).

Tool compatibility

• Trufflehog v3; timeout flags on git and filesystem scans.

Variant phrasings

trufflehog timed out scanning

Same handling.

trufflehog scan killed on large repo

Identical; scope or chunk.

Why it happens

Trufflehog walks every commit and runs detectors on each diff. History size multiplies work, and the default deadline assumes a modest repo.

Edge cases

• Shallow clones scan fast but miss history; use them only for pre-merge checks.
• Binary-heavy repos slow detectors; excluding binaries helps a lot.
• CI time limits may kill the job before trufflehog's own timeout; raise both.

Not specified by the original author.

TL;DR

A 4GB monorepo defeats single-pass scans. Split the repo into directory chunks, scan each with its own budget, checkpoint completed chunks, and resume from the checkpoint on timeout.

Error

scanner agent failed with timeout scanning a 4gb monorepo

Steps

1. Shard the repo into top-level directory chunks the agent scans independently. Expected: bounded work per chunk.
2. Give each chunk its own timeout and retry, independent of the others. Expected: one slow chunk does not kill the run.
3. Write a checkpoint file as each chunk completes. Expected: resume skips finished chunks.
4. Exclude generated, vendored, and binary-heavy directories up front. Expected: far less work.
5. Merge chunk reports into one findings file at the end. Expected: complete coverage.

When to use

• Agent scans timing out on very large repos.
• Designing resilient scan orchestration.

When not to use

• Timeouts on small repos (fix the scanner or its config).
• One-off manual scans (just raise the timeout).

Tool compatibility

• Gitleaks, trufflehog; agent orchestration with checkpoints.

Variant phrasings

scan times out on huge repo

Chunk it.

agent scan killed on monorepo

Same sharding fix.

Why it happens

Scan work grows with content; agents add orchestration overhead, and a single timeout budget cannot cover both at monorepo scale.

Edge cases

• Cross-chunk findings (same secret in two dirs) need dedup at merge.
• Checkpoints must be atomic; partial writes corrupt resume.
• Shard boundaries should follow team ownership for triage.
