* fix(ci): pin deb builds to ubuntu-22.04 and enforce the fleet glibc floor
The v1.60.0 debs failed to install on Raspberry Pi OS bookworm:
socktop : Depends: libc6 (>= 2.39) but 2.36-9+rpt2+deb12u14 is to be installed
Cross-compiled binaries link against the RUNNER's (multiarch) glibc, so
the runner picks the minimum glibc the packages demand. ubuntu-latest
migrated from 22.04 (glibc 2.35) to 24.04 (glibc 2.39) between the
1.50.x releases and now, silently raising the requirement past the
Debian-12 fleet.
Pin the build job to ubuntu-22.04 (2.35 — satisfied by bookworm's 2.36)
and add a post-build gate that reads each .deb's computed libc6
requirement and fails the run if it exceeds the fleet floor, so the next
runner migration turns into a red build instead of a fleet-wide apt
error.

* fix(ci): extract the libc6 version, not the 6 in 'libc6'
The floor gate's second grep matched the trailing digit of the package
name before the version ('libc6 (>= 2.34)' -> '6'), failing every
target. sed capture group instead; verified against realistic Depends
strings.

* chore: bump all crates to 1.60.1
The 1.60.0 debs were built against glibc 2.39 and never installed on the
bookworm fleet; rather than force-moving the tag, the rebuilt release
ships as 1.60.1. Nothing was published to crates.io at 1.60.0.

* fix(agent): drop processes that no longer exist
`refresh_processes_specifics` was called with remove_dead_processes = false
against a long-lived System, so the agent accumulated every process it had
ever seen and went on reporting them. Measured on a Pi 5 after a few hours of
build churn: 21,648 processes reported, 289 actually running, growing a few
every poll.
Three consequences, in ascending order of how confusing they are:
* unbounded memory growth, and every poll iterating ~75x more entries than
it should
* process_count — the client's "Top Processes (N total)" — is meaningless
* a process you kill keeps its row forever, because the agent keeps sending
it. Killing it again reports "no longer exists", since the kernel is
telling the truth and the agent is not.
The third is how this was found: no amount of client-side reconciliation could
fix a list whose producer never forgets anything.
Passing `true` is only correct because these two sites use
ProcessesToUpdate::All. With `Some(pids)` sysinfo treats every process outside
the list as dead and removes it, so the per-PID refresh in
collect_process_metrics must keep `false` — noted in a comment there.
Verified by driving the TUI against a rebuilt agent: reported count 292 vs 290
real, and a killed row is removed once and never reappears.

* feat(socktop): kill a local process from the TUI
btop-style process termination, for local agents only. The signal is sent by
socktop itself through a direct sysinfo call — nothing is transmitted to the
agent, and the agent and connector have no kill capability at all.
Why local-only: the PIDs on screen are reported by the agent, and the signal is
sent with socktop's own OS privileges. A PID is therefore only meaningful, and
only safe to act on, when the agent lives on this machine; acting on a remote
agent's PIDs would signal whatever unrelated local process happened to share
that number. local::agent_is_local treats an address as local when it is
loopback or when an ephemeral bind succeeds (which only works for an address on
one of our own interfaces, so it also covers reaching our own agent by LAN IP),
requires every address a hostname resolves to to be local, and fails closed.
* `t` on the selected process, and `t` inside Process Details. One key for
both: `k` scrolls the thread table in the modal, so it could not be reused
there.
* The confirmation offers Terminate (focused first, so a reflexive Enter is
the safe one), Force kill, and Cancel. Keeping SIGKILL behind a second
button rather than a second keybinding means the destructive option has to
be chosen deliberately.
* The selection hint gained the key, but only for a local agent — advertising
a key that deliberately does nothing is worse than no hint. Same for the
details modal's help line.
The list is reconciled after a signal rather than left to the next poll. A
signalled PID goes on a watch list re-checked each metrics tick, because SIGTERM
is a request: the process is usually still alive at signal time, and its row
should go when it actually exits (or stay, if it ignores the signal). PIDs
confirmed gone are remembered briefly, since the agent serves Processes from a
1500ms cache and would otherwise hand back a pre-kill snapshot. A selection
whose process has left the list is dropped, and the details view closes for a
process that no longer exists — including when it dies on its own, which
previously flipped that modal to "Agent Update Required" because the wire cannot
distinguish "no such PID" from "endpoint unsupported".
Also fixes two pre-existing UI faults found on the way:
* The selection hint was sized from its full label including the process name
and skipped entirely when that exceeded the pane width — so it vanished
exactly when a long-named process was selected. The name is now the elastic
part, and widths are measured in columns rather than bytes.
* Confirmation and Info dialogs laid their content out over the whole modal
rect instead of the block's inner rect, putting the first line of text on
the border row, and fell into the catch-all 70%x50% sizing arm, so a
one-line question got half the screen. They now size to their content and
use the theme's colors like the connection-error modal does.

* fix(kill): close stacked details view, guard PID reuse, scale settle with interval
Review fixes for the process-kill feature:
1. Killing from INSIDE the details view left it open forever, frozen on
the dead process (reproduced live): the 'Signal sent' Info modal sits
on top when the death is confirmed on the next tick, the old top-only
close_process_details missed it, gone-PIDs are processed once, and the
details-poll fallback was gated on the selection the kill had just
cleared. The close now removes the dead PID's view wherever it sits in
the stack — which also retires a dead parent's view from under a child
in a navigation chain, so backing out lands on the process list rather
than a frozen corpse view. Tests updated to the new semantics, plus a
regression test for the Info-stacked case.
2. PID-reuse guard: the PID comes from an agent snapshot and the
confirmation can sit open indefinitely, so by signal time the kernel
may have recycled the number. kill_local_process now takes the name
the user confirmed and refuses to signal a PID whose current owner
does not match ('PID N now belongs to X, not Y').
3. A transient request error no longer closes the details view: with
process_details_answered set, any Err was read as 'process gone',
including socket blips. The view now closes only when the PID is also
absent from the agent's own process list.
4. PROC_CACHE_SETTLE scales with the user's processes interval (floor at
the old 1.6s default-TTL value), and the tombstone lifetime rides on
top of it — users who raise the agent's Processes TTL raise the client
interval to match, so the interval is the best client-side signal for
how stale an agent snapshot can be.

* fix(kill): resume polling for the details view that resurfaces from a chain
Reported: kill still orphaned a window via Enter (child details) -> P
(parent details) -> t (terminate parent). The parent's view closed
correctly, but the child's view underneath resurfaced with no selection
(forget_process_row had cleared it — it pointed at the parent) and wiped
data; the selection-gated details poll never refilled it.
close_details_for_gone_process now retargets the selection to the
uppermost remaining ProcessDetails view (looking through stacked
Info/Confirmation modals) and makes the poll due immediately — the same
retarget SwitchToParentProcess performs on the way down the chain.
Same class of hole in plain navigation, fixed alongside: Esc-ing back
from a parent view left the selection on the PARENT, so the resurfaced
child-titled view refilled with the parent's data. The dismiss arm now
retargets the selection to whatever details view it lands on.
Both verified live: child -> P -> kill parent -> child view resurfaces
populated and updating; child -> P -> Esc -> child view shows the child.

* chore: dead-code sweep
- Delete socktop_connector/src/connector.rs: orphaned since 08f248c removed
'pub mod connector;' during the modularization refactor. Never compiled
(verified under default, wasm, and workspace feature combos) but shipped
in the crates.io tarball and contained an outdated copy of the TLS
verifier — a trap for anyone patching the pinning bug in the dead copy.
- Delete empty socktop/src/ws.rs, tracked editor backup ui/.modal.rs.backup,
and stray test_thiserror.rs at the repo root.
- Delete the two LEGACY #[allow(dead_code)] process input handlers; the
header-click render test now exercises the live _with_selection handler
instead (better coverage of the real path).
- Drop unused sysinfo dependency from the socktop client.
- Replace stale 'temporarily increased for testing' comment on
COMPRESSION_THRESHOLD (it already held the production value).

* fix(connector): make certificate pinning real; disable Nagle
Security: with --verify-hostname off (the default), the old NoVerify
verifier accepted ANY server certificate — the CA loaded from --tls-ca
was never consulted, so the documented pinning was a no-op and the
connection was trivially MITM-able. Replace it with PinnedCertVerifier:
the presented end-entity cert must be byte-identical to a cert in the
--tls-ca file (any cert in a multi-cert PEM matches, supporting
rotation). Signature validation now uses the ring provider's full
algorithm set instead of a hardcoded 3-scheme list. Empty PEM files
fail fast instead of failing closed per-handshake.
The --verify-hostname path is unchanged (WebPki root-store validation).
Also: the third argument of connect_async_tls_with_config is
tungstenite's disable_nagle flag, not a verification toggle — we were
passing verify_hostname there, leaving Nagle ON for default users. Pass
true unconditionally, and disable Nagle on the plain ws:// path too;
socktop exchanges small request/response frames where Nagle only adds
latency.
Client now consumes the connector via a dual path+version dep so these
fixes are in local builds and CI before the crates.io publish (cargo
strips the path on publish). Connector version -> 1.51.0.
Verified E2E: agent A's cert connects to agent A; agent B's cert
against agent A fails the handshake (the rpi-worker-1 wrong-PEM
scenario); --verify-hostname against a 127.0.0.1 SAN still connects.

* fix(agent): GPU worker thread, async journalctl, correctness + cache fixes
Lightweight:
- GPU collection moves to a dedicated worker thread that owns the gfxinfo
handle for the process lifetime. gfxinfo's active_gpu() runs a full NVML
init/teardown (~20ms, blocking) and we were paying it on the async
runtime for every collect — measured at ~80% of the agent's entire
active CPU on a GPU machine. The handle holds Rc<Nvml> (not Send), so a
thread + mpsc/oneshot channel pair confines it; a zero-total-VRAM reply
is treated as a dead session (driver reload) and re-probed.
- journalctl now runs via tokio::process instead of blocking one of the
two runtime workers for the duration of the subprocess.
- TtlCell (state.rs) replaces the four hand-rolled static TTL caches; a
cached negative result now counts as fresh, so hosts with no matching
temp sensor or GPU stop rescanning every request. Single lock+clone on
the GPU cache hit path (was two).
Correctness:
- Process/child CPU times are now microseconds as documented; they were
milliseconds, rendering 1000x too small next to (correct) thread times.
- Non-Linux per-process CPU%% clamps AFTER dividing by core count; a
4-cores-busy process on an 8-core box reported 12.5% instead of 50%.
- Journal timestamps are real RFC 3339 UTC plus an additive timestamp_us
field (sorting is now numeric); the old strings were Debug-formatted
SystemTime mangled by string replace.
- Partition detection uses /sys/block on Linux: whole-disk filesystems on
names like nvme0n1 or zram1 are no longer misclassified as partitions.
One shared parent_disk_name() replaces two inline copies.
- New sampled_at_ms on the metrics payload (additive) records when the
snapshot was actually collected, so clients can compute exact rates
across the agent's TTL cache.
Security/robustness:
- key.pem is created 0600 (was umask default 0644, world-readable) and
pre-1.51 keys are tightened on startup.
- Per-PID detail/journal caches now evict (60s max age, 64 entries max);
they previously grew without bound under PID-walking clients.
- The two per-PID ws handlers collapse into one generic helper.
- /proc/<pid>/stat parsing unified in one comm-safe module.

* fix(tui): responsive input, request timeouts, poisoned-stream reconnect
R1 — input latency: the event loop drained input once per iteration, then
slept the whole metrics interval; keys and wheel events queued for up to
500ms (or the full interval at slower rates) and applied in bursts. The
input block is extracted to drain_input() and the tail sleep replaced by
a deadline wait in <=33ms poll slices that handles and repaints input the
moment it arrives. Verified: help modal opens <150ms into a 2000ms tick.
R2 — freeze-proofing: metrics/processes/disks requests had no timeout; a
half-dead connection left ws.next() pending forever and froze the TUI
with no way to quit (raw mode eats Ctrl+C as an unread key event). All
requests now carry a 5s budget.
C3 — desync: replies are matched to requests by order alone, so a timed-
out request's late reply would shift every subsequent reply off by one.
Any timeout now treats the stream as poisoned and goes through the
reconnect flow — a fresh stream is aligned by construction. The modal
endpoints additionally mark process details unsupported (flag resets on
modal close/selection change) so a detail-less agent doesn't cause a
reconnect loop. While disconnected the fetch path idles: recovery belongs
to the manual/auto retry paths instead of 5s-timeout hammering.
C7 — fit::truncate_middle_cols replaces util::truncate_middle: display-
width aware and char-boundary safe; the byte-slicing version panicked the
draw loop on non-ASCII device names.
Verified live: agent kill -9 mid-session -> error modal in <3s, q exits
while disconnected, r reconnects and resumes.

* chore: version 1.51.0, path-dep the wasm examples, README notes
- socktop, socktop_agent, socktop_connector -> 1.51.0.
- socktop_wasm_test and zellij_socktop_plugin consume the in-repo
connector via path deps so wasm-feature API drift is caught at PR time
instead of after publish. Immediately proved out: the wasm requests
module needed the new sampled_at_ms field, invisible to native builds.
- zellij plugin gains the standalone [workspace] marker (it could not be
cargo-checked in-tree at all before). NOTE: its lib.rs has pre-existing
compile errors unrelated to the connector (static mut STATE conflicts
with register_plugin!, missing BTreeMap import) — needs its own rework,
out of scope here.
- README: sampled_at_ms in the example payload.

* fix(review): restore Agent Update Required flow, command field, axis alignment
Fixes from Jason's hands-on verification of the branch:
1. Old-agent messaging regression (this branch): a detail-request timeout
went through the loud poison/reconnect flow, burying the ProcessDetails
modal's 'Agent Update Required' message under a connection-error modal.
Old agents IGNORE unknown messages (no late reply, no desync), so the
optional per-PID endpoints now use quiet_reconnect(): swap the stream
silently (still safe against merely-slow agents) and let the modal show
its message. Only a failed reconnect surfaces loudly. Verified against
a real v1.40.0 agent: message shows, session stays healthy.
2. Draw starvation (this branch): an agent that never answers get_metrics
put the loop in fetch->timeout->poison->restart cycles that never
reached the draw call — permanently blank TUI. The iteration now paints
before fetching, and a second consecutive metrics timeout trips a
circuit breaker: persistent 'Agent is not responding' error, recovery
left to the manual/30s retry paths. Verified against a 0.9-era agent.
3. Command & Details pane blank (pre-existing on master): the minimal-
refresh optimization dropped cmd/exe/cwd from the detail endpoint's
ProcessRefreshKind, so process.cmd() had nothing to return. Restored
with UpdateKind::OnlyIfNotSet — immutable values, read once per PID.
Regression test added; journal E2E re-verified (100 entries render).
4. Scatter-plot axis misalignment: Y labels used a fixed 4-char field from
the era when CPU times were 1000x too small; honest millisecond values
(e.g. 136114) blew through it. Labels now right-align to the widest
value per frame and X labels/titles share the dynamic padding.

* feat: journal access notice, 1.60.0, install script, changelog, riscv protoc fallback
- Journal pane now distinguishes 'no entries' from 'no journal access':
journalctl exits 0 with empty output when the agent's user simply can't
see the target's entries (demo mode / user-run agents), explaining
itself only on stderr. The agent forwards that hint as an additive
JournalResponse.notice and the client renders it with practical advice.
Verified E2E via a stub journalctl emulating the unprivileged case.
- Version 1.60.0 across all crates (1.51 would read fine, but the repo's
scheme is 1.40/1.50/…, and a literal 1.6.0 would sort BELOW 1.50.0 in
semver). All user-facing version strings already come from
CARGO_PKG_VERSION — a stale binary was the only way to see an old one.
- scripts/install.sh: build-from-source install/upgrade for the test
fleet (Linux + macOS). Detects in-repo checkouts, installs rustup when
missing, replaces a systemd socktop-agent service binary in place and
restarts it, requires system protoc on riscv64.
- build.rs (agent + connector): fall back to $PROTOC / PATH when
protoc-bin-vendored has no binary for the host (riscv64) — native SBC
builds previously panicked in the build script.
- CHANGELOG.md covering v1.50.0 -> 1.60.0.

* fix: untrack zellij plugin build dir; installer updates all PATH copies
- Remove zellij_socktop_plugin/target from git (3,577 files committed by
accident in bf6ac87): the root .gitignore anchors /target to the repo
root, so the standalone plugin's own build dir wasn't covered. Ignore
target/ at any depth (also fixes the pre-existing
'/socktop-wasm-test/target' entry, which pointed at a hyphenated path
that doesn't exist).
- install.sh now updates EVERY copy of socktop/socktop_agent on PATH,
not just $PREFIX: a stale 'cargo install' in ~/.cargo/bin shadows
/usr/local/bin on most PATHs, so an install could 'succeed' while
'socktop --version' kept reporting the old release. Extra copies that
can't be written are warned about, not fatal, and the script now
prints which binary is actually active on PATH at the end.

* feat(installer): manage the socktop-agent systemd service
Upgrade path (unit already present): NEVER touch the unit file — it is
the operator's config (SSL, tokens, ports live there as Environment=
lines). Only the binary at the unit's own ExecStart path is replaced,
then the service restarts. Flags/args preserved by construction.
Fresh path (no unit): full first-time setup mirroring the deb postinst
and the agent-service docs — create the socktop system user/group and
/var/lib/socktop, install docs/socktop-agent.service (ExecStart rewritten
to wherever this run installed the agent; embedded fallback for old
refs), daemon-reload, enable --now, and print how to turn on TLS/token.
Also: system-level operations get their own sudo decision (SYS_SUDO) —
previously they inherited the PREFIX sudo flag, so a writable --prefix
made the service section run groupadd/systemctl unprivileged and die.
No sudo at all now skips service management with a warning instead of
failing the install.
Both branches dry-run verified with stubbed systemctl/sudo.

* fix(installer): don't bind fresh agent services onto occupied ports
The Orange Pi install put the new service straight into a crash-restart
loop: the unit's default --port 3000 collided with a Docker service
already publishing 3000 (Umami; Gitea and friends default there too).
Fresh installs now scan 3000/3001/3010/3231/3232 via ss and configure
the unit on the first free port, warning loudly when 3000 was taken and
printing the resulting ws:// URL. Upgrades still never touch the unit.

* fix(agent): detect NVIDIA GPUs on distros without the unversioned NVML soname
On Debian and derivatives the NVIDIA driver ships only libnvidia-ml.so.1
(the unversioned symlink belongs to the dev package), and nvml-wrapper's
default init dlopens the unversioned name — so gfxinfo reported 'No GPU
found' on a fully functional RTX A2000 host while nvidia-smi worked
fine. Arch-family distros ship the symlink, which is why the desktop
never showed this.
The GPU worker now falls back to initializing NVML directly with the
versioned soname when gfxinfo's probe fails, collecting name/util/vram
through the same handle-caching path. nvml-wrapper was already in the
tree via gfxinfo — same version, no new build cost.

* fix(agent): box the NVML handle variant (clippy large_enum_variant)
CI clippy runs with -D warnings; Nvml is a large struct next to the
16-byte Box<dyn Gpu> variant.

* fix(installer): survive self-modification mid-run; sturdier unit detection
Root cause of the mixed-up second install on the A2000 host: when run
from the clone it manages, the script's own git checkout/merge REPLACES
scripts/install.sh while bash is still executing it. Bash reads scripts
lazily by byte offset, so it resumed parsing the NEW file at the OLD
offset and executed an arbitrary tail of it — observed as the fresh-
service path running on a host whose unit already existed: the port scan
saw the still-running old service on 3000 and silently wrote a new unit
on 3001, while enable --now on the already-active service changed
nothing until a manual daemon-reload.
Fix: the whole script now runs inside main(), invoked as
'main "$@"; exit $?' so bash parses everything up front and never
reads the file again after main returns (the exit lives in the same
parse unit — demonstrated necessary: with a bare 'main "$@"' ending,
bash still executed the swapped file's trailing content after main
returned).
Also: unit existence is now checked with 'systemctl cat' instead of
grepping the full list-unit-files output.

Three panes painted two independent pieces of text onto one row with nothing
reserving space between them, so below roughly 105 columns the right-hand piece
was simply drawn over the tail of the left one:
socktop — host: cachyos-gaming | 🔒✗ TLS | (a: about⏱ 500ms metrics | 2000ms
The width arithmetic used str::len(), a byte count, so the emoji in these strings
overstated their width and left orphaned glyphs at the right edge as well. The
process table had the same problem in a different form: it handed the layout
solver a fixed, over-constrained column set, so a narrow pane crushed the
percentage-sized Name column to nothing while fixed-width PID and Mem % kept
their full width — losing the one field that identifies a process.
Add ui::fit (measure in terminal columns, truncate on character boundaries, pick
the richest wording that fits) and give each pane a priority ladder:
- Header: drop the key hints, then the TLS/token badges, then the
"socktop — host:" prefix, then the metrics/procs words, and only then shorten
the hostname. Hostname and intervals are what survive longest.
- CPU pane: drop the "CPU Temp:" label, then the now:/avg: labels, then the
average, then the temperature's decimal, and the temperature itself last — a
thermal warning outranks a second decimal place.
- Process table: Name is unconditional; CPU %, then Mem, then PID, then Mem %
are added as the pane widens, so Mem % is the first to go and Name the last.
Also fixes sort-header clicks, which resolved against a Layout that omitted the
column spacing the Table renders with, so a click landed off by up to four
columns. Covered by a test that clicks each label where it is actually drawn.

In a short window the fixed root layout runs out of rows and the CPU graph and
per-core bars are what collapse first: the header, gauges and process table hold
fixed heights, so at ~18 rows the top row is left with no drawable interior and
both panes disappear entirely.
Add a second layout, entered automatically once the Disks pane can no longer show
even one complete disk card:
- Disks is dropped — it is the pane that degrades worst when partly drawn.
- Memory and Swap move side by side into the row Disks vacated.
- GPU collapses to a single full-width line (utilisation and VRAM, no device
name), and is omitted entirely on a host that reports no GPU.
- The reclaimed rows go to the CPU panes, with the surplus above their floor
shared with the bottom half so the process table still grows with the window.
`--compact` pins the layout at any size.
The root layout was duplicated in three places (the draw path and both input
hit-testing paths), which would have drifted the moment a second layout existed.
Move it into ui::layout as the single source of truth and have all three callers
go through it.

Demo mode spawns a socktop_agent child process, but the agent is a separate
crate that `cargo install socktop` does not pull in. When it was missing, the
raw spawn error propagated to main and printed as
`Error: Os { code: 2, kind: NotFound, message: "No such file or directory" }`,
which gives the user nothing to act on.
Introduce DemoAgentError so a NotFound spawn failure is distinguishable from
other io errors, and print the path we looked for plus the `cargo install
socktop_agent` fix. Other spawn errors still propagate as before.

The Windows CI matrix surfaced an `unused_variables` warning at
metrics.rs:846 — `let now = std::time::Instant::now();` was bound
unconditionally but only consumed inside a `#[cfg(feature = "logging")]`
tracing::debug! call.
This block lives in the non-Linux `collect_processes_all`, so the Linux
CI never compiles it and never sees the warning. Same shape as the
`processes_ttl_ms` Windows fix from earlier: a binding whose only
consumer is cfg-gated needs to be cfg-gated too.

* Make GPU support optional to enable RISC-V builds without libdrm
- Add 'gpu' feature flag (enabled by default)
- Make gfxinfo dependency optional
- Provide no-op GPU metrics when gpu feature disabled
- Disable GPU support for RISC-V builds in CI (libdrm unavailable)
- All other architectures (amd64, arm64, armhf) still get GPU support
* feature gate GPU stats for arm v7
* specify correct package names.
* install aarch64-linux-gnu-gcc build dep
* specify correct package name
* add RISC-V GCC compiler
* add .cargo to gitignore to elimicate issue with riscv64-linux-gnu-gcc linker in config.toml
* add gcc-arm-linux-gnueabihf linker fore armv7
* set correct x-compile lib gcc-aarch64-linux-gnu for arm64 builds.
* add ports.ubuntu.com to sources
* Add ARM64 as a foreign architecture
* fixe for ARM64 build.
* security.ubuntu.com` aNNOYING
* apt repo github page
* copy output to apt repo
* fix secrets path
* fix secrets path
* change build dep
* Fix postinst message box alignment
* ci(deb): restrict APT publish to v* release tags
Previously the workflow built and published on every push to master
and feature/debian-packaging in addition to v* tags. That meant the
gh-pages APT repo got overwritten on every commit with same-version
.debs, causing apt clients to see a phantom "update available" each
time and burning ~5-10 min of cross-compile CI per merge.
After this change:
- PRs into master still cross-build .debs as a sanity check.
- v* tags build, publish to gh-pages, and create a GitHub release.
- workflow_dispatch remains as the manual escape hatch.
- master pushes no longer trigger this workflow (ci.yml still runs).

- Add Up/Down arrow key handling in help modal
- Display scrollbar when content exceeds viewport
- Update title to indicate scrollability
- Fixes content cutoff on small terminal windows
This commit implements several major improvements to the TUI experience:
1. CPU Average Display in Main Window
- Show average CPU usage over monitoring period alongside current value
- Format: "CPU avg (now: 45.2% | avg: 52.3%)"
- Helps identify sustained vs momentary CPU spikes
2. Max Memory Tracking in Process Details Modal
- Track and display peak memory usage since monitoring started
- Shown as "Max Memory: 67.8 MB" in yellow for emphasis
- Helps identify memory leaks and usage patterns
- Resets when switching to different process
3. Fuzzy Process Search
- Press / to activate search mode with bordered search box
- Type to fuzzy-match process names (case-insensitive)
- Press Enter to auto-select first result
- Navigate results with arrow keys while typing
- Press c to clear filter
- Press / again to edit existing search
Search box features:
- Yellow bordered box for high visibility
- Active mode: "Search: query_"
- Filter mode: "Filter: query (press / to edit, c to clear)"
Technical implementation:
- Centralized filtering with get_filtered_sorted_indices()
- Consistent filtering across display, navigation, mouse, and auto-scroll
- Proper content area offset calculation for search box
- Real-time filtering as user types
4. Code Quality Improvements
- Created ProcessDisplayParams and ProcessKeyParams structs
- Created MemoryIoParams struct for process modal rendering
- Reduced function arguments to stay under clippy limits
- Exported get_filtered_sorted_indices for reuse
Files Modified:
- socktop/src/app.rs: Search state, auto-scroll with filtering, max memory tracking
- socktop/src/ui/cpu.rs: CPU average calculation and display
- socktop/src/ui/processes.rs: Fuzzy search, filtering, parameter structs
- socktop/src/ui/modal.rs: Updated help modal with new shortcuts
- socktop/src/ui/modal_process.rs: Max memory display, MemoryIoParams struct
- socktop/src/ui/modal_types.rs: Added max_mem_bytes field
Testing:
- All tests pass
- No clippy warnings
- Cargo fmt applied
- Tested search, navigation, mouse clicks, and auto-scroll
- Verified on both filtered and unfiltered process lists
Breaking Changes:
- None (all changes are additive features)
Closes: (performance monitoring improvements)
This check in offers alpha support for per process metrics, you can view threads, process CPU usage over time, IO, memory, CPU time, parent process, command, uptime and journal entries. This is unfinished but all major functionality is available and I wanted to make it available to feedback and testing.
