History pane: Tool runs and Session log views; the log filtered, saved as CSV or JSON Lines, cleared or turned off (#797, part 2) - #1324
Part 2 of #797: the app's own view of the session log that part 1 (#947) keeps (Session::log). As @Mavrick-F proposed on #1216, it goes in the History pane, which gets two views. They are named for what each record is:
Tool runs: the tools run on the project, as History shows them now. They are saved with the project, and each can run again.
Session log: everything done in the session. It shows:
the commands run in the session, newest first: whether each worked, its id, how long it took, when it started (UTC), its error, and its parameters on one line (all of them on hover; a right-click copies the parameters or the command id);
a filter by part of the command's id (layer., export, any case) and Failed only;
how many match: "12 entries", "3 of 12 entries", or "The newest 200 of 840 entries" past the 200 it lists;
Save Log As…: the whole log as CSV or JSON Lines, as the name's extension says (CSV without one), through project.exportLog; in the browser, where project.exportLog can't write a file, it is downloaded as CSV;
Clear Log (project.clearLog) and Log Commands (project.logCommands), with a note while logging is off.
The pane changes the log only through its commands, so Save, Clear and Log Commands are logged and work as a script's would. It reads Session::log directly (as History reads gp_history), the way project.log selects, without going through JSON each frame.
The newest 200 entries listed (sessionlog::SHOWN). The log holds up to 10,000; listing them all each frame would make the pane slow. The count says how many match, and Save Log As… writes them all. The rows listed, with their parameters as text, are kept between frames while the log's length, its newest entry and the filters are as they were (SessionLog::newest), so a repaint doesn't go through the log again.
The filter is a substring of the command's id, in any case, friendlier when typing than project.log's exact id or prefix ending in a dot.
The writer moves to SessionLog::write (from cmd/project.rs, unchanged: the same CSV with formula-safe cells, the same JSON Lines), so the browser download writes the same CSV as project.exportLog. LogEntry::time_utc gives the CSV's first column and the pane's time.
Clear Log asks nothing, as Clear History doesn't; the log says it was cleared (its own entry).
No new ui.* command and no ribbon button: History is opened as before (ui.pane.history).
Limits
Strings aren't translated here (i18n/*.tsv left to the release).
The browser download is CSV only, and isn't itself an entry in the log: project.exportLog can't write a file there, so the pane downloads the CSV it writes. A saved file on the desktop is logged. The user guide says so.
a_long_log_shows_its_newest_entries: past 200, the newest listed and the count said.
the_session_log_is_saved_cleared_and_turned_off: .csv, .jsonl and a name without extension (CSV); each save in the log; Clear Log leaves its own entry; Log Commands off, with its note, and nothing more logged.
Part 1's engine tests pass unchanged with the writer moved (the_session_log_records_each_command_run_in_the_session checks the CSV and JSON Lines exports).
cargo xtask ci on Windows with RUSTGIS_LANGUAGE=en (cargo fmt --all --check, cargo clippy --workspace --all-targets -- -D warnings, cargo test --workspace, layers), on main at 656f6410: passed (3,073 tests, 0 failed; two earlier runs alongside other CIs hit a timing flake in pmtiles_archives_frame_the_map_on_their_bounds, which passes alone and is outside this change).
The History pane gets two views, as Mavrick-F proposed on opengeos#1216: Tool runs
(the tools run on the project, saved with it, each can run again) and
Session log. The log view lists the session's commands newest first (the
newest 200 that match, with the count), each with whether it worked, its
time (UTC), how long it took, its error and its parameters (on hover in
full; right-click copies them), filtered by part of the command's id and to
those that failed. Save Log As... writes it through project.exportLog (CSV
or JSON Lines by the extension, CSV without one), or downloads it as CSV in
the browser; Clear Log and Log Commands run project.clearLog and
project.logCommands.
The CSV/JSON Lines writer moves unchanged to SessionLog::write, with
LogEntry::time_utc, so the download writes what project.exportLog does.

The engine now tracks session-log changes and dropped entries, and provides CSV and JSON Lines export. The History pane adds a filterable Session log view with display, clear, logging, and save controls.
Changes: Project Session Log
Layer / File(s)
Summary
Log tracking and export crates/engine/src/project_log.rs, crates/engine/src/cmd/project.rs, crates/engine/src/tests.rs
SessionLog tracks changes and dropped entries, formats UTC timestamps, and writes CSV or JSON Lines. project.exportLog uses the log writer and reports dropped entries after a successful export.
History pane and log display crates/ui-egui/src/lib.rs, crates/ui-egui/src/panes.rs, crates/ui-egui/src/sessionlog.rs
The History pane adds a Session log view with case-insensitive command filtering, a failed-only filter, and a 200-entry display cap. It shows command details and log counts.
Save controls and documentation crates/ui-egui/src/sessionlog.rs, docs/user-guide/workspace.md
The pane saves logs through browser downloads or a file dialog, and provides controls to clear the log and toggle command logging. The guide describes the views, filters, retention, and export options.

Explanation
The title names the History pane's two new views (Tool runs and Session log) and the log's filtering, CSV/JSON Lines saving, clearing, and turning off. These match the changeset, which adds the Session log view in the History pane (sessionlog.rs, panes.rs), the SessionLog::write export, and the clear and logging toggles. The title is long at 129 characters and includes a PR number reference, so it is wordy, but it still describes the main change accurately.

Full details: Description check
Explanation
The description follows the repository template's main sections: Summary, Testing, and Related issue. It also adds a Choices and Limits section. The Testing section lists the new UI tests, the engine test results, and the CI run. The UI evidence section is missing. The template marks that section as required, and the author did not state whether the change is visible. The change adds a new visible History view, so the UI evidence section should contain screenshots (after-only, since the UI is new), or the 'No visible UI change.' line should be removed. The Related issue section is also not filled in. The description references #797 and #1216 in the body, but it does not use the template's 'Part of #...' format in that section.
Resolution
Replace the 'No visible UI change.' line in the UI evidence section with an after-only screenshot of the new Session log view in the History pane, since the change adds visible UI. Fill in the Related issue section with a reference in the template format, for example 'Part of #797'. The description already mentions #797 in the body, so this change only requires the template entry.

I found no crash, data-loss or correctness bugs in the changed code. The CSV and JSON Lines output is byte-for-byte the same as before the move, the filters and counts check out, and the export errors surface as notices. I checked the log's select and entries, the project.exportLog format rules, the dialog stubs, the web download helper, and the rustfmt width. The prior-review set was empty, so nothing was skipped as already raised.
Bugs
Browser save skips the command, so it is not logged (medium, ~75%). The web branch of save() writes the CSV directly and never runs project.exportLog. The PR says Save is logged as a script's would be, so the two platforms record different things. See inline comment on sessionlog.rs:146.
Security
None found. The export path still goes through the same extension and format checks, and failures are notified.
Performance
Per-frame work scales with the whole log (low-medium, ~40%).select runs every frame: it lowercases up to 10,000 command ids while a filter is set, clones the newest 200 entries with their params, and serializes each visible row's params again. See inline comment on sessionlog.rs:58.
Quality
A test string in in_the_browser_the_session_log_is_downloaded_as_csv contains a raw line break instead of \n. Left for the release quality pass.
Clear Log clears the whole log even when the filter shows a subset, and it asks nothing. This is the stated design, but the button label does not say so.
AGENTS.md
No screenshots in the PR body (high, ~95%). This PR changes a visible pane. AGENTS.md asks for an after screenshot for new UI, and the body has none.
Unit labels built with format! (low, ~30%). The "{} ms" and "{} UTC" labels are not wrapped in tl! or i18n::fmt. See inline comment on sessionlog.rs:116.
…ave noted
- The rows listed, with their parameters as text, are kept in the pane's state
while the log's length, its newest entry (SessionLog::newest) and the filters
are unchanged, so a repaint doesn't go through the log again.
- "{ms} ms" and "{time} UTC" go through i18n::fmt.
- The user guide says the browser download isn't itself an entry in the log.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
None found that I'm confident in. I could not compile or run the tests here (no shell), so the compile-level checks are by reading: the select, LogEntry: Clone + PartialEq, pick_save/PICKED, download, i18n::fmt and logCommands signatures all match their call sites.
Security
None new. csv_cell (formula-safe cells) moved unchanged into project_log.rs, and the pane's hover text warns that the log may name files and addresses before it is shared.
Performance
sessionlog.rs:249 (inline comment posted), low, about 90%: this re-raises the earlier per-frame-cost thread on that line. The thread was marked fixed and says a repaint "clones nothing", but the key still clones the newest LogEntry (params up to about 4 KB) and query is lowercased on every frame. Hits should compare by reference.
Quality
sessionlog.rs:261: the closure parameter t shadows the Tokens argument t. It is harmless but easy to misread.
project_log.rsSessionLog::write(w, csv: bool): a boolean flag argument. An enum would read better, though this is a small point.
sessionlog.rs around 508–511: the CSV header assertion is split across a literal newline. A \n escape would read better.
sessionlog.rsClear Log runs with no confirmation and irreversibly drops the whole log. The PR states this as a choice, so it is noted here for the maintainers, not as a defect.
AGENTS.md
High confidence: the PR body has no screenshots, but AGENTS.md requires "after" screenshots for new UI (the History pane's Session log view), with a link to the attachment guidance in docs/contributing.md#documentation.
Quality points above are left for the release quality pass per AGENTS.md; no separate replies are posted for them.
Pre-existing, not in this diff (for context)
project_log.rspush drops the oldest entries past LOG_LIMIT (10,000) and LOG_PLUGIN_LIMIT with no notice. The new pane and its docs say "Save Log As… writes the whole log", and the count reads as complete. This is about 70% likely to conflict with the AGENTS.md "Never silent" rule. It is worth a notice or a note in the pane.
Prior threads
3 earlier threads on this PR were reviewed. 2 are resolved (the browser-save logging gap, which the author documented, and the format! unit labels, which were moved to i18n::fmt) and I left them alone. 1 was re-raised as the inline comment above, because the code changed and the claim in the reply is not accurate.
Change size
Compared with the base branch: the whole PR, merge base 656f641 to head 0c93bb6.
…nothing
The stored key is compared field by field against the log's length, its newest
entry (by reference) and the filters as typed; the query is lowercased and the
key cloned only when the rows are picked again. The closure's `t` no longer
shadows the Tokens.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
I found no bugs or crash paths. The two inline comments below are low-severity. I also flagged one AGENTS.md gap in the PR body.
Bugs
None found. I checked SessionLog::select ordering (oldest-first tail, so .rev() shows newest first), the moved CSV writer (same output as before), the cache-key logic, and the browser download path. Tests only use .unwrap(), which clippy.toml allows.
Security
None found. CSV cells are still formula-escaped after the move, and the save path goes through project.exportLog on desktop.
Performance
Low, about 75%: row() builds new strings for every visible row on every repaint (i18n::fmt ×2, time_utc, the truncated params line). That contradicts the reply's "a repaint allocates nothing" claim. Inline comment posted at sessionlog.rs:146.
Quality
Low, about 20%: the cache key (len, newest, query, failed) can miss a push at the log limit when the new entry equals the old newest. Inline comment posted at sessionlog.rs:69.
Nits, left for the release quality pass: tabs() returns a bool that drives early return, so a name like view_tabs would read better. The cache rebuild inside pane() could be its own function.
AGENTS.md
About 90%: AGENTS.md requires screenshots for any visible change (before and after for changed UI, after for new UI). This PR adds a new History view and rows, and the PR body has no screenshots or image links.
I did not re-raise the four earlier threads on sessionlog.rs. Two were addressed in the code (cache cost, per-frame cost), one was answered with a documented limit (browser save not logged), and one was addressed (i18n of ms/UTC). Concerns left alone: 4.
I could not run cargo fmt, clippy or the tests because this session has no shell. Everything above comes from reading the code.
Change size
Compared with the base branch: the whole PR against main (merge base 656f641 to PR head 1fac74f).
… once
- SessionLog counts its changes (an entry added, a clear): the pane's cache
key is that count and the filters, so an entry equal to the newest one at the
log's limit isn't missed. newest() goes.
- Each listed row keeps its duration, UTC time and one-line parameters, made
when the rows are picked, not on each repaint.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Session log view can show a stale newest row after a merged undo step (Medium-high, about 85%). SessionLog::join_last (crates/engine/src/project_log.rs:411, unchanged in this PR) replaces the last entry in place when a command merges into the previous undo step. That happens on normal command runs, for example repeated arrow-key nudges. It does not bump the new changes counter, so the pane's cache key still matches and the newest row keeps the old millis, params and at. The saved files are correct because export reads the log directly. Fix: add self.changes = self.changes.wrapping_add(1); after *last = e;, plus a regression test. The inline comment is on line 399, the nearest changed line, because GitHub rejects comments on unchanged context lines.
Security
None found. The export path rejects extensions other than .csv/.jsonl, CSV cells are formula-escaped, and the browser download reports its notice.
Performance
None new. I checked the cache key and the per-frame work: a repaint that changes nothing clones and formats nothing, and the cache is reset when changes or the filters change.
Quality
Nit (high confidence): the browser-save test in crates/ui-egui/src/sessionlog.rs (around line 343) has a raw newline inside the string literal instead of \n. It works but reads oddly. Left for the release quality pass.
AGENTS.md
No violations found. There are no unwrap/expect/panic calls in non-test code, UI strings use tl!/i18n::fmt, the docs/user-guide/workspace.md change matches the behaviour, and the wasm path uses download, not the file system.
Not verified: I have no build or test runner here, so I did not compile the change or run cargo xtask ci. Compile-level checks (egui API calls, borrows) are from reading the code only.
Prior threads: 7 threads exist. I left 6 alone because they are answered or resolved and the code they point at has not regressed. The seventh (the cache key missing an entry at the log limit) is fixed for push, but the same miss remains through join_last, so I raised that as a new finding above.
Change size
Compared: the whole PR against main (merge base 656f641 to PR head c87b5cf).
join_last replaces the newest entry in place (a held key's nudges); it now
bumps the change count, so the History pane's Session log picks its rows again
and shows the joined duration and parameters.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
None confirmed. I checked select ordering (oldest-first, so the pane's .rev() gives newest-first), the join_last change counter, every log mutation path (push, join_last, clear), the CSV escaping and the export format logic. They are correct as written.
Security
None found. CSV cells are formula-guarded through csv_cell, and the JSON Lines and CSV writers are unchanged apart from being moved.
Performance
None blocking. The cache key (changes, query, failed) avoids per-frame work, and each row's texts are made once when the rows are picked. A held-key nudge rebuilds the 200 rows each frame. That is acceptable at this size, so I raise nothing.
Quality (nits, grouped; per AGENTS.md these may wait for the release quality pass)
crates/ui-egui/src/sessionlog.rs, the browser test: "time_utc,…,params\n" is written as a literal with a raw newline inside it. It works but reads badly. \n in the literal is clearer. (Low, about 90%.)
The ok/failed marker is a colored dot with no text, so status is conveyed by color alone. Failures do show error text, which helps. (Low, about 50%.)
Row stores the parameters twice (params and the truncated line). This is a small memory cost at 200 rows, so it is harmless. (Low, about 30%.)
AGENTS.md
Screenshots missing (about 85%). This PR changes visible UI (the History pane's new tabs, filter, list and buttons). AGENTS.md asks for screenshots in the PR description (before and after for changed UI, after for new UI). The body has none. The PR should attach them, from ui_shot or a desktop run.
Never silent (about 60%). The oldest entries are dropped past LOG_LIMIT and LOG_PLUGIN_LIMIT with no notice. This predates the PR, but the new pane and Save Log As… describe the held entries as "the whole log". Inline comment posted at crates/engine/src/project_log.rs:401.
Checked and fine: no unwrap, expect or panic in non-test code. User-visible strings use tl! or i18n::fmt. The browser path is wasm-safe, and the export command never opens a dialog.
Prior reviews
7 threads already exist on this PR, and I left all of them alone. Each is resolved or outdated and answered in the head code (for example, join_last now bumps changes at line 417, and the cache is compared in place). I raised nothing again.
Change size
Compared with main (merge base 656f641 to PR head e261c99).
SessionLog counts the entries dropped past LOG_LIMIT and LOG_PLUGIN_LIMIT
(`dropped`, reset by a clear). The History pane's Session log says "The N
oldest entries were dropped past the log's limits", project.exportLog's notice
says the saved file lacks them, and the user guide says both give the count.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
None confirmed. The earlier threads on this PR (join_last, the drop count, cache keys, the ms/UTC literals, the per-frame allocations) are fixed in the code I read. The browser-save-not-logged point is answered in the docs. I checked the cache key against session replacement: the app never replaces app.session, so the changes counter can't go stale that way.
Security
None found.
Performance
Nothing new worth raising. With a filter set, kept lowercases each entry whenever the log changes and the pane is open. That is O(10k) per change, and the earlier threads already covered the per-frame cost.
Quality
None raised beyond the findings below.
AGENTS.md
Never silent, browser path (inline, sessionlog.rs:200): about 55% confidence. The browser CSV download doesn't carry the dropped-entries count that the desktop export's notice gives. This is new; the earlier thread covered only the desktop export and the pane.
Test both ways (inline, tests.rs:21819): about 80% confidence. The dropped-entries notice is tested only in the lossy case. Nothing checks that a clean export gives no notice.
Screenshots (PR-level, about 70% confidence): the PR adds a visible new pane, and AGENTS.md asks for an "after" screenshot in the PR for new UI. The PR body has none, so it should add one, linked by URL from opengeos/rustgis-assets.
Prior threads: 8 earlier concerns were already raised. I left all 8 alone: 1 answered and 7 fixed or outdated. I re-raised none. The browser-download point above is new, not a repeat.
Change size
Compared with the base branch: the whole PR against main (merge base 656f641 to PR head edbe855).
The browser's Save Log As… download says how many of the oldest entries the
log dropped past its limits, as the desktop export's notice does. The tests
check both ways: nothing said when nothing was dropped.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Bugs: None found. I checked the engine changes (SessionLog::write, dropped/changes counters, join_last, the export notice), the pane's row cache and filters, and the browser download path. Nothing crashes, drops data silently, or miscounts. Confidence in that: about 80%. I could not compile or run the tests here.
Security: None found. The CSV formula guard and the log's secret handling are unchanged.
Performance: None significant. The row cache is keyed on changes() and the filters. The pane is inside the right-pane ScrollArea, so 200 rows are scrollable. The browser download buffers the whole CSV in memory, up to tens of MB at the 10,000-entry limit. That is inherent to download_bytes and I'd leave it.
Quality:
Split string literal in the browser-download test (sessionlog.rs:361). It contains a real newline instead of \n. High confidence. Left for the release quality pass.
Success or failure is shown only by a green or red dot, with no text (sessionlog.rs:167). About 60% confidence. Left for the release quality pass.
AGENTS.md:
"Test both ways" is not met for the pane's dropped-entries line (sessionlog.rs:113). No test fills the log past LOG_LIMIT and checks that the note appears, or checks that a clean log has none. About 85% confidence. This is a rule violation, so it should be fixed in this PR.
The PR body has no screenshots of the new History views. AGENTS.md asks for an "after" screenshot for new UI. High confidence.
Earlier concerns left alone: 10 review threads already exist. All are answered or fixed, and none needed re-raising. The one I left alone is the browser download not being logged, since the author answered it and the user guide states the difference.
Change size
Compared with main (merge base 656f641 to PR head 2a7d615).
…ped note
- The status dot says "Worked" or "Failed" on hover and to a screen reader.
- a_log_past_its_limit_says_what_it_dropped checks the pane's note past the
limit; a clean log shows none.
- The browser test's header literal is one line.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Bugs: None found. I checked the new SessionLog counters (changes, dropped, join_last), the CSV writer moved to SessionLog::write (same output as before), the pane's row cache key, the export format and extension rules, and the browser download path. Nothing I could confirm from the code produces wrong output or a crash.
Security: None found. CSV cells still go through csv_cell, so formula-leading cells stay neutralised after the move. Parameters are clipped at push time as the user guide says, and the guide warns users to check an export before sharing it.
Performance:
Low, about 40% confidence: in the browser, save() builds the whole CSV in a Vec<u8> before downloading. At the 10,000-entry limit with about 4 KB of parameters per entry, that is up to roughly 40 MB in memory. SessionLog::write's doc comment says a long log "isn't held as text first", which does not hold for this caller.
Quality:
Low, about 90% confidence: the wrapped header literal in in_the_browser_the_session_log_is_downloaded_as_csv is still split across two lines. The earlier reply said this was fixed in 75947d4, but the head still has it. Inline comment posted with a suggestion block.
Medium-high confidence, test coverage: the PR says the newest-first test checks that "Tool runs shows the tools again", but the harness never draws history(), so that view is not tested. Inline comment posted.
AGENTS.md: No violations found. Interface text uses tl! or i18n::fmt, the browser and desktop save paths both report what was dropped, and the never-silent tests cover both the lossy and clean cases.
Prior reviews: 13 earlier threads, all resolved and not outdated. I re-raised one (the wrapped literal) because its reply does not match the code. I left the other 12 alone, including the browser-save-not-logged concern, which the PR now documents as a known difference.
Change size
Compared: the whole PR against main (merge base 656f641 to PR head 75947d4).
Dropped-entry notice is inaccurate for plugin-limit drops (about 55% confidence). Past LOG_PLUGIN_LIMIT, the log removes the oldest plugin entry, not the oldest entry overall. The pane, the export and the browser download all say "the N oldest entries were dropped", which contradicts the user guide. Posted inline at crates/ui-egui/src/sessionlog.rs:115.
I checked the other paths and found no defect. join_last is only reached when logging is on (lib.rs:1022 gates it), so the counter bump there is safe. select returns oldest-first, so the .rev() in the pane gives newest-first. Export format handling rejects a mismatched or unknown extension with an error. The browser download reports its own failure.
Security
None found. CSV cells keep the formula-safe quoting, and the save path goes through the user's own file pick.
Performance
None found. Rows are rebuilt only when the change counter or the filters change, and select runs only on that rebuild.
Quality (left for the release quality pass)
The dropped-entry notice has three different wordings (export, pane, browser download).
The "Save Log As…", "Clear Log" and "Log Commands" row sits below up to 200 rows, so it is far from the filter at the top.
In docs/user-guide/workspace.md, the new History paragraph sits between the section's intro and its "What goes in" bullets. The phrase "as a saved file is" reads awkwardly.
Row::of compares a char-truncated string's byte length to decide on the ellipsis. It is correct, but it reads oddly.
AGENTS.md
Missing screenshots (about 85% confidence). AGENTS.md requires an "after" screenshot for new UI. The PR body has none.
The rest of the AGENTS.md rules look followed: no unwrap or indexing in non-test code, notices go through Session::notify with counts, interface strings use tl! and i18n::fmt, pick_save and download have wasm stubs, and the dev-dependencies are declared.
Earlier concerns
I left 15 earlier review threads alone. All of them are resolved or answered, and the browser-save-not-logged thread is answered by the author in the user guide and PR limits.
Change size
Compared with main (merge base 656f641 to PR head 030ec00).
Browser "Save Log As…" reports dropped entries even when the download fails. download_bytes discards the bool that download returns, so the "oldest entries were dropped" notice can describe a file that was never delivered. Inline comment posted. Confidence: about 50%.
Security
No findings.
Performance
No findings. The cache key (changes, query, failed) avoids per-frame work, and the earlier per-frame clone and lowercase concerns are fixed.
Quality
The frame-level interact(Sense::click()) may shadow the hover tooltips inside each row (the Worked/Failed dot and the full-parameters line). Inline comment posted. Confidence: about 40%. The tests don't check hover, so this needs an app check or a hover test.
Two wordings for the same drop notice, in the pane and in the export and browser paths. A shared helper would keep them in step.
Row::of compares byte lengths (line.len() < params.len()) to decide on the ellipsis. It works, but chars().count() > 120 would read more clearly.
AGENTS.md
The PR body has no screenshots. AGENTS.md requires them for any visible change (before and after for changed UI, after only for new UI), and this PR adds visible History views. Confidence: high.
The join_last change-counter fix, the dropped counter, and the tl!/i18n::fmt use all look right against the rules. Test coverage for the lossy and clean cases is present.
Already raised (left alone)
16 review threads already exist on this PR. 15 are resolved and were answered by the author, so I did not post them again. The one still open is the plugin-limit wording ("the N oldest entries were dropped"): the code still says this, so the concern stands and I did not repeat it.
Change size
Compared with the base branch: the whole PR against main (merge base 656f641 to PR head 030ec00).
Add a populated history case to the Tool runs check.
The Tool runs check at sessionlog.rs:290-294 runs only with an empty gp_history. An implementation that always shows "Tools you run appear here." would still pass. Run a tool before switching to Tool runs, then assert that a record's tool name is rendered.

Extend the Tool runs check around `query_by_label` to cover populated

The test checks only that a notice contains dropped past the log's limits. A notice with any count passes, including an incorrect one. The test clears the log directly, which records no entry. The map.new run then adds one entry. Pushing LOG_LIMIT + 3 more entries drops four, so the notice should state 4.

Review comment at @crates/ui-egui/src/sessionlog.rs at line 393:
Update the browser download test’s dropped-notice assertion to verify the notice
reports exactly four dropped entries, rather than only checking for the generic
dropped-limit phrase; preserve the existing test setup and failure context.
The engine assertion at crates/engine/src/tests.rs:21705-21707 checks that changes() increases and that the joined entry's millis is 5. It does not render the History pane.
The Session log cache at crates/ui-egui/src/sessionlog.rs:92-97 rebuilds rows only when changes() changes. No test in the Session log test module joins an entry and then renders again at the same log length. If the cache key were changed to log.len(), a joined entry would keep its old row, and the current tests would still pass.
Add a test that renders the pane, joins the newest entry with join_last, renders again, and checks that the view shows the joined duration.

Add a test in the Session log test module that renders the History pane, calls

the displayed duration is 5. Reuse the existing rendering and assertion helpers,
and ensure the test covers the unchanged log length with updated `changes()`.

- The log counts drops past LOG_LIMIT and past the plugins' limit apart,
and one wording (SessionLog::dropped_said) serves the pane, the export
and the browser download.
- The browser save says what the file lacks only when the download was
delivered (download_bytes returns whether it was).
- A row's right-click is sensed behind its contents, so the Worked dot's
and the parameters' hover texts show; the row's labels aren't
selectable, so a right-click on them still opens the menu.
- One entry reads "1 entry". Tests for a populated Tool runs view, a
joined entry in the view, the exact drop count and hover/right-click.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Tool runs, populated:the_session_log_lists_the_commands_run_newest_first now adds a run to gp_history after the empty case, and checks that its tool name and message show and the placeholder is gone.
Exact drop count: the browser download test asserts "not in it: 4 oldest entries were dropped past…" (one map.new plus LOG_LIMIT + 3 pushed).
Joined entry in the view: the new test a_joined_entry_is_shown_as_it_is_now renders the pane, calls join_last on the newest entry and renders again. It checks "5 ms" replaces "2 ms" at the same length, so a cache keyed on len() would fail it.
While there, a single entry now reads "1 entry", not "1 entries".
Bugs: None found. I checked the paths the earlier threads don't cover:
select returns the newest matching entries in order, and the pane lists them newest first.
The pane's changes cache key is safe: Session is only constructed in one place (lib.rs:796), and no code replaces app.session or s.log.
join_last, push, clear and the drop counters all bump or count correctly.
download_bytes now returns a bool that matches download's own success or failure. Its existing callers ignore the bool as a statement, so they still compile.
The export path's format/extension logic and write_atomic_with are consistent.
Security: None found. CSV cells keep the formula guard, the export path is checked against its extension, and the browser download uses a fixed file name.
Performance: None new. The pane caches its rows, and the cache-hit path allocates nothing. Each filter keystroke still lowercases every command id (up to 10,000) once, which is acceptable at these sizes. Not worth raising.
Quality:
SessionLog::dropped() (project_log.rs) is public but only the engine tests call it. The pane and the exports use dropped_said(). Low priority, left for the release quality pass.
The cache tuple in sessionlog::State could be a small struct. Left for the release quality pass.
workspace.md has one over-long wrapped line (around line 818). Left for the release quality pass.
AGENTS.md:
Inline comment posted on crates/ui-egui/src/sessionlog.rs:222: the browser notice session-log.csv: not in it: … uses format!, where AGENTS.md asks for i18n::fmt (about 70% confidence). The suggestion uses i18n::fmt.
Already raised, left alone: I left 18 earlier threads alone. Each is either resolved, or answered by a change that the code now shows. The two answered ones are the browser save not being logged (answered and documented) and the browser download being CSV-only (documented in the user guide). Nothing in those threads needed re-raising.
Change size
Compared with the base branch (merge base 656f641 to PR head a8080db), the whole PR.
The changed assertion checks the ; not in it: prefix and the drop wording, but not the number. A notice that reports 1 oldest entries were dropped still passes. A regression in the export count would not fail this test.
The expected count is seven. The export notice is built in export_log before Session::run records the export entry. Two entries remain from the clear and logging commands, and the overflow loop pushes LOG_LIMIT + 5 more. Seven entries are evicted.
Suggested fix
.iter()
- .any(|n| n.text.contains("; not in it: ") && n.text.contains("oldest entries were dropped past the log's limit of 10000")),+ .any(|n| n.text.contains("; not in it: 7 oldest entries were dropped past the log's limit of 10000")),

Assert the clipboard text for both context menu actions.
The right-click test checks only that Copy Command is visible. A handler that copies the wrong text, or no text, still passes. Extend this test, or add one beside it, to click each action and assert the CopyText output. Use the row for map.new. Its nonempty name parameter enables Copy Parameters.

Included review availability: This review used your included allowance. Your plan provides up to 8 included reviews per hour; 7 remain after this review.
@coderabbitai Both follow-ups are test additions with no bug behind them: the exact drop count in the engine's export-notice test, and the clipboard text for Copy Parameters and Copy Command. I've left them for the release quality pass rather than starting another review round.
For best results, initiate chat on the files or code changes.
@elpidioassinaturas Understood. Leaving the exact export-notice drop-count assertion and the Copy Parameters / Copy Command clipboard assertions for the release quality pass is reasonable.
This follows the repository guidance to treat minor review suggestions as advisory. I won’t insist on these additions in this PR.
Would you like a follow-up issue to track both test additions?

Summary
Part 2 of #797: the app's own view of the session log that part 1 (#947) keeps (
Session::log). As @Mavrick-F proposed on #1216, it goes in the History pane, which gets two views. They are named for what each record is:layer.,export, any case) and Failed only;project.exportLog; in the browser, whereproject.exportLogcan't write a file, it is downloaded as CSV;project.clearLog) and Log Commands (project.logCommands), with a note while logging is off.Choices in this PR
Session::logdirectly (as History readsgp_history), the wayproject.logselects, without going through JSON each frame.sessionlog::SHOWN). The log holds up to 10,000; listing them all each frame would make the pane slow. The count says how many match, and Save Log As… writes them all. The rows listed, with their parameters as text, are kept between frames while the log's length, its newest entry and the filters are as they were (SessionLog::newest), so a repaint doesn't go through the log again.project.log's exact id or prefix ending in a dot.SessionLog::write(fromcmd/project.rs, unchanged: the same CSV with formula-safe cells, the same JSON Lines), so the browser download writes the same CSV asproject.exportLog.LogEntry::time_utcgives the CSV's first column and the pane's time.ui.*command and no ribbon button: History is opened as before (ui.pane.history).Limits
