[Autoloop] build-tsb-pandas-typescript-migration by github-actions[bot] · Pull Request #98 · githubnext/tsessebe

github-actions · 2026-04-10T23:53:09Z

🤖 This PR is maintained by Autoloop. Each accepted iteration adds a commit to this branch.

Program Goal

Build tsb — a complete TypeScript port of pandas, one feature at a time. This is an open-ended program that runs continuously, always adding the next piece of pandas functionality.

Current Status

Best metric: 30 pandas_features_ported (main baseline: 28)
Iterations: 176 total
Branch: autoloop/build-tsb-pandas-typescript-migration

Latest Iteration (176 — Recovery)

This iteration established the canonical long-running branch by cherry-picking two previously validated but unmerged features:

na_ops.ts: isna/notna/isnull/notnull (scalar/Series/DataFrame), ffillSeries/bfillSeries/dataFrameFfill/dataFrameBfill
pct_change.ts: pctChangeSeries/pctChangeDataFrame — percentage change with periods, fillMethod, limit, and axis options

Both features include full test coverage and interactive playground pages.

Implements pandas missing-value utilities as standalone exported functions: - `isna` / `notna` / `isnull` / `notnull` — detect missing values in scalars, Series, and DataFrames (mirrors pd.isna / pd.notna) - `ffillSeries` / `bfillSeries` — forward/backward fill for Series with optional `limit` parameter - `dataFrameFfill` / `dataFrameBfill` — column-wise or row-wise fill for DataFrames with optional `limit` and `axis` parameters Metric: 28 → 29 pandas_features_ported Run: https://github.com/githubnext/tsessebe/actions/runs/24263385922 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Implements pctChangeSeries() and pctChangeDataFrame() mirroring pandas.Series.pct_change() / pandas.DataFrame.pct_change(). - periods: configurable lag (positive = backward, negative = forward) - fillMethod: "pad" (default), "bfill", or null (no fill) - limit: cap consecutive fills - axis: column-wise (default) or row-wise for DataFrame Full test coverage: unit tests, edge cases, and fast-check property tests. Interactive playground page at playground/pct_change.html. Run: https://github.com/githubnext/tsessebe/actions/runs/24266545401

playground/index.html: kept both PR's pct_change card and main's new feature cards
pct_change.{ts,test.ts,html}: accepted main's version (correct .size API, Biome formatting)

Evergreen: Merge Conflict Resolved

This PR had a merge conflict with main. I resolved all 3 conflicts and updated the branch.

Conflicts Resolved

File	Resolution
`src/index.ts`	Kept PR exports: `ffillSeries`, `bfillSeries`, `dataFrameFfill`, `dataFrameBfill`
`src/stats/index.ts`	Kept PR exports from `na_ops.ts`
`playground/index.html`	Kept both PR's `pct_change` card and main's `insert_pop` card

Approach

The branch was linearized (rebased onto current main as a single squash commit) to keep the push size manageable. The final state includes all of main's features plus the PR's na_ops feature.

Evergreen: Merge conflict resolution attempt

I resolved the merge conflicts in 3 files by merging main into the PR branch:

src/index.ts: Added ffillSeries, bfillSeries, dataFrameFfill, dataFrameBfill exports on top of main's version
src/stats/index.ts: Added the same exports from ./na_ops.ts on top of main's version
playground/index.html: Added the pct_change feature card on top of main's version

The merge commit 8e4a87b was created locally but could not be pushed due to the push_to_pull_request_branch tool returning "Branch does not exist locally" — the MCP server does not appear to see the locally created commit. This will be retried on the next run.

🌿 Evergreen: Merge Conflict Resolution

Status: Resolved ✅

Conflicts fixed:

src/index.ts — kept PR's ffillSeries, bfillSeries, dataFrameFfill, dataFrameBfill exports from ./stats/index.ts
src/stats/index.ts — kept PR's ffill/bfill exports from ./na_ops.ts
playground/index.html — kept PR's pct_change feature card alongside main's new cards

Merge commit: b41493aa47805be294ec12c0c23c489fa4139100

⚠️ Note: The push_to_pull_request_branch safe-output tool returned an error ("Branch does not exist locally"). The merge commit is ready locally but could not be pushed via the automated tool. Manual push required.

🌿 Evergreen: Push Failed — Infrastructure Limit

Merge conflict resolution: ✅ Complete (commit b41493aa created locally)

Push result: ❌ Blocked

Root Cause

The PR branch is 212 commits behind main. The incremental patch to push the merge resolution is ~8.1 MB, which exceeds the max_patch_size limit of 1024 KB.

What was fixed locally:

src/index.ts — kept PR's ffillSeries, bfillSeries, dataFrameFfill, dataFrameBfill exports
src/stats/index.ts — kept PR's ffill/bfill exports from ./na_ops.ts
playground/index.html — kept PR's pct_change card alongside main's new insert_pop card

Fix Required

To unblock automated Evergreen runs on this PR, the workflow needs one of:

Increase max_patch_size to ≥ 8192 KB, or
Set patch_format: bundle in the push_to_pull_request_branch config (bundles bypass the size check and preserve merge topology)

Alternatively, the autoloop system can create a new PR branch that starts from current main.

🤖 Evergreen: Resolved merge conflict with main.

Changes made:

Kept PR's na_ops feature exports: ffillSeries, bfillSeries, dataFrameFfill, dataFrameBfill in src/stats/index.ts and src/index.ts
Kept PR's pct_change playground card in playground/index.html

The conflict was caused by main advancing after this branch's last merge. Resolved by taking the superset of both branches' additions.

🔧 Evergreen: Conflict Resolution Attempted

I resolved the merge conflicts between this branch and main locally:

src/index.ts — Kept PR's exports for ffillSeries, bfillSeries, dataFrameFfill, dataFrameBfill (from na_ops.ts)
src/stats/index.ts — Kept PR's exports from na_ops.ts
playground/index.html — Kept PR's pct_change feature card and incorporated main's updates

However, the PR was closed during the workflow run (at ~15:31 UTC). The push could not be completed because the safeoutputs push tool could not find the local branch. The resolved merge is committed locally as 4650f99.
