Baixar wtop 1.3.0 per a Windows

Four new sensors, web search on the selected process, and a substantial rewrite of the collection
path onto native NT and Win32 calls. Two new keys: i and ?.
Disk, battery, uptime and effective CPU clock
A Disk panel shows per-physical-disk read/write throughput and a busy percentage, taken from PDH
rather than gopsutil — disk.IOCounters reports cumulative counters keyed by volume, so two
volumes on one spindle double-count, and it has no equivalent of % Idle Time. Capacity bars are
drawn for each fixed volume.
Volumes are reconciled against the real physical disks before being shown. DRIVE_FIXED is not
proof a volume exists: Google Drive's mount reports fixed, reports NTFS, and mirrors the system
drive's exact byte size. Only volumes that some \PhysicalDisk instance claims survive, so no
phantom copy of C: appears.
Per-process disk I/O arrives as DISK R and DISK W columns, sortable like any other. These
cost no additional syscalls — ReadTransferCount and WriteTransferCount were already sitting
unused in the SYSTEM_PROCESS_INFORMATION buffer the process collector parses. Validated by writing
64 MiB and confirming ~58 MiB attributed within the sampling window.
The status bar gains battery and power state (AC/battery, charge, time remaining, battery-saver),
system uptime, and the effective CPU clock including turbo, read from
% Processor Performance against the nominal base clock. A boosting CPU reads above 100% of base, so
the figure is deliberately not clamped. On a desktop with no battery the power field is omitted
rather than left blank.
Web search on the selected process
? looks the selected process up in your default browser, on whatever search engine that browser is
actually set to — read out of the browser's own profile, so a Chrome or Edge switched to DuckDuckGo
searches DuckDuckGo rather than Google or Bing.
A child process is searched together with its nearest differently-named ancestor, so a bare
msedgewebview2.exe becomes GoogleDriveFS.exe msedgewebview2.exe and you find out which
application is actually hosting it.
Two things this required, for anyone reading the code: a Chromium browser cannot be told to run a
search from the command line — everything after -- goes through Chromium's URL fixup, so
msedge.exe -- "a.exe b.exe" silently navigates to http://a.exe%20b.exe/. There is no flag for it.
Gecko browsers do have one (--search), which is why the two families are driven differently. The
Chromium engine is therefore read from Preferences → default_search_provider_data; Edge leaves
that key null and keeps a readable copy in mirrored_template_url_data, so both are tried.
wtop itself opens no connection. The request is made by your browser, at your keypress, and is
subject to that search engine's privacy policy. PRIVACY.md
now says so explicitly.
Collection path rewritten onto native calls
Process collection is now a single NtQuerySystemInformation(SystemProcessInformation) call,
replacing 1,500+ Win32 syscalls and 16 worker goroutines per tick. Network collection goes directly
to GetIfTable2. NVIDIA GPUs are read in-process through nvml.dll, falling back to DXGI, PDH and
nvidia-smi — no subprocess on the common path.

The first frame is populated immediately; the "Initialising…" screen is gone.
Fixes
- IDXGIAdapter1::GetDesc1 was calling the wrong vtable slot (11 instead of 10), which invoked
GetDesc2 and overwrote 8 bytes of stack with a struct larger than the caller expected. This
affected non-NVIDIA GPUs specifically, where DXGI is the path taken. If you run AMD or Intel
graphics, this is the reason to take this release.
- Disk busy % no longer reports a false 100% when an idle counter is missing or failed; the map
is checked before the rate is derived.
- A recycled PID no longer reports a garbage CPU spike on its first tick. Both the CPU and I/O
deltas are now gated on CreateTime matching, so a new process cannot inherit a dead one's
counters.
- Narrow terminals no longer panic in the GPU panel. gpuNameLine measures with
ansi.StringWidth and truncates on rune boundaries, fixing a negative slice bound below three
columns of name width and mid-rune splits on multi-byte names.
- Panels can no longer overflow their reserved height. lipgloss Width() word-wraps and
Height() is only a minimum, so a single over-long line rendered a panel taller than the caller
reserved — measured through the real View(), a 50×40 terminal rendered 44 rows and pushed the
status bar off-screen. Clipping now happens inside RenderPanel.
- Two process rows come back. computeTableHeight was reserving a header row that
bubbles/table.SetHeight already accounts for.
Layout
The panel row is Memory plus as many rotating panels as the terminal can hold. GPU, Network and Disk
share those slots and page through them with i.
──────────────┬───────────────────────────────
Terminal width│Panel row
──────────────┼───────────────────────────────
below 110 │Memory + one rotating panel
──────────────┼───────────────────────────────
110 – 159 │Memory + two rotating panels
──────────────┼───────────────────────────────
160 and wider │Memory + all three; i is a
│no-op
──────────────┴───────────────────────────────
DISK R and DISK W appear at 120 columns and disappear together below it. Sorting by a hidden
column still works — the status bar is the authoritative sort indicator. At the default rotation
offset the rendering is identical to v1.2.1 at every width.
Deliberately not included
Drive and CPU temperatures. IOCTL_STORAGE_QUERY_PROPERTY with
StorageDeviceTemperatureProperty returns ERROR_INVALID_FUNCTION on a current Samsung NVMe, even
though the handle opens unelevated and StorageDeviceProperty on that same handle returns real data
— the driver simply doesn't implement it. MSAcpi_ThermalZoneTemperature returns "not supported",
and SMART via WMI returns Access Denied without elevation. Real core temperatures need MSR access
through a signed kernel driver, which is incompatible with a single unprivileged binary.
Also
Snyk dependency and code scanning on every push and PR; required checks now always report rather
than going missing on a filtered path; the Go toolchain and golangci-lint pins are mirrored so the
linter cannot silently fail open against a newer stdlib.
