ci: increase Windows dev drive size from 12GB to 20GB by Copilot · Pull Request #8779 · rolldown/rolldown

Copilot · 2026-03-19T02:56:42Z

see https://github.com/rolldown/rolldown/actions/runs/23277544016/job/67683621586

The Windows cargo-test CI job is failing with linker errors (LNK1318, LNK1180) because the 12 GB dev drive fills up during the Rust debug build (test binaries, PDB files, .rlibs, Cargo registry cache).

Change

Bump drive-size from 12GB → 20GB in .github/workflows/reusable-cargo-test.yml

- uses: samypr100/setup-dev-drive@30f0f98ae5636b2b6501e181dfb3631b9974818d # v4.0.0
  if: runner.os == 'Windows'
  with:
    drive-size: 20GB  # was 12GB

Original prompt

Problem

The Windows cargo-test CI job is failing with linker errors caused by running out of disk space on the dev drive.

Failing job: https://github.com/rolldown/rolldown/actions/runs/23277056014/job/67682204464

Errors from the log:

error: linking with `link.exe` failed: exit code: 1140
  = note: LINK : fatal error LNK1318: Unexpected PDB error; LIMIT (12) 'E:\target\debug\deps\integration-ca7a8f5a011d2f91.pdb'

error: could not compile `rolldown` (test "integration") due to 1 previous error

error: linking with `link.exe` failed: exit code: 1180
  = note: E:\target\debug\examples\watch.exe : fatal error LNK1180: insufficient disk space to complete link

error: linking with `link.exe` failed: exit code: 1180
  = note: E:\target\debug\deps\rolldown-e3e41cd18eeec507.exe : fatal error LNK1180: insufficient disk space to complete link

error: Recipe `test-rust` failed on line 63 with exit code 1

Root Cause

The setup-dev-drive step in .github/workflows/reusable-cargo-test.yml is configured with drive-size: 12GB. The Rust build output — including debug artifacts, PDB files, test binaries, and the Cargo registry/cache — is filling up the 12 GB dev drive, causing:

LNK1318 (PDB error / LIMIT 12): the drive is at or near capacity when PDB files are being written
LNK1180: the drive has completely run out of space during linking

Fix

Increase the dev drive size in .github/workflows/reusable-cargo-test.yml from 12GB to a larger value (e.g. 16GB or 20GB) to give the Windows build enough room to compile and link the full Rust test suite.

File to change: .github/workflows/reusable-cargo-test.yml

Change:

      - uses: samypr100/setup-dev-drive@30f0f98ae5636b2b6501e181dfb3631b9974818d # v4.0.0
        if: runner.os == 'Windows'
        with:
          drive-size: 12GB

        if: runner.os == 'Windows'
        with:
          drive-size: 20GB

Please increase the drive-size from 12GB to 20GB (or whatever size is appropriate to give comfortable headroom above current usage).

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: Fix cargo test windows CI https://github.com/rolldown/rolldown/actions/runs/23277056014/job/67682204464

Assistant: Now I have a clear picture of the failure. Let me analyze the errors:

Root Cause: Insufficient disk space on the Windows runner's Dev Drive

The CI log shows two distinct linker errors on Windows:

LNK1318: Unexpected PDB error; LIMIT (12) — the PDB file hit the 12-file limit (related to the Dev Drive being 12GB and running out)
LNK1180: insufficient disk space to complete link — explicit disk exhaustion

The setup-dev-drive action currently allocates only 12GB for the drive. Given the size of the rolldown project (many crates being compiled in parallel to the target dir on that same Dev Drive), it's running out of space. The fix is to increase the dev drive size.

Let me also check if there are any other recent issues or PRs related to this:

Assistant: Now I have a clear picture of the issue. Let me create the PR to fix it.

Root Cause Analysis:

The Windows CI job is failing with two related linker errors:

LNK1318: Unexpected PDB error; LIMIT (12) — the PDB file limit on the 12 GB dev drive was hit
LNK1180: insufficient disk space to complete link — the dev drive ran out of disk space

The current configuration uses samypr100/setup-dev-drive with drive-size: 12GB. The build is running out of space (or hitting the PDB limit caused by the drive being too full) when trying to compile and link the full Rust test suite on Windows. The fix is to increase the dev drive size.

Assistant: We're waiting for your response to the tool call dialog to continue with creating the pull request.

In the meantime, here's a summary of the root cause and fix:

Root Cause: Windows Dev Drive Out of Disk Space

The CI job failed with two linker errors during the cargo test step:

LNK1318 (PDB LIMIT 12): The PDB file writer hit the 12 GB cap, indicating the dev drive was at capacity.
LNK1180 (insufficient disk space): The drive was completely full when linking the .exe binaries.

The build target directory (E:\target) lives on a virtual dev drive set up by samypr100/setup-dev-drive. The drive is currently configured to 12 GB in .github/workflows/reusable-cargo-test.yml:

      - uses: samypr100/setup-dev-drive@30f0f98ae5636b2b6501e181dfb3631b9974818d # v4.0.0
        if: runner.os == 'Windows'
        with:
          drive-size: 12GB
          drive-format: ReFS
          env-mapping: |
