Opening and parsing on the browser main thread froze the tab for the
whole load; the file selector path already loads in a worker thread,
so boot now uses the same thread, progress modal, and error dialogs.
The preloaded data package made every ?t= load download embed.tracy
as well. The startup glue now fetches embed.tracy only when no URL is
given, into the same /url.tracy slot, and the boot code has a single
open path.
Version and integrity checks throw from the View constructor, which
was outside the try/catch guarding the file open, so a bad argv trace
terminated the process. Catch and report it there as well.
The compare load thread caught only UnsupportedVersion, so a
corrupted or otherwise unloadable second trace escaped the thread as
std::terminate. Catch the same set as the main trace load and route
it to the existing bad-version dialog.
Exception catching was off by default in the web build, so the
try/catch handlers around trace loading were dead code and any
failure unwound through the page.
glfw 3.5.1 enables OBJC build-wide under CMake 4.x, remapping nfd's
nfd_cocoa.m to a language its scope never loaded; generate then fails on
CMAKE_OBJC_COMPILE_OBJECT. Initialize OBJC at the top level so sibling
scopes get the rules.
The raw sumSq paired with a self/running mean yielded the raw variance
inflated by the squared mean gap. Accumulate the vector's own sum of
squares alongside its sum, like compare and frame statistics do.
Block sizes weren't checked against the file length, so truncated files
made the decompression threads read off the mapping. Validate framing
(u32 size + payload) before the mapping and threads exist; also reject
zero-stream or empty files.
Sections are packed into timeline rows purely by length, so sections
from different categories share rows and the same category can move
between rows along the timeline. When categories mark different kinds of
activity (game levels, loading screens, cutscenes) this makes the row
layout hard to read.
The new "Group by category" option in the section options lays out each
category in its own set of rows, in category identifier order, with the
existing length-first packing applied within a category. Off by default,
so the current layout is unchanged unless the option is enabled. Only
shown when the trace has more than one section category.
The CMake option only controlled whether NFD is built and linked, but
the file selector code is guarded by the TRACY_NO_FILESELECTOR macro,
which the build never defined - configuring with -DNO_FILESELECTOR=ON
failed to compile (nfd.h not found in TracyFileselector.cpp,
BackendWayland.cpp and BackendGlfw.cpp). Define the macro for the
profiler target when the option is set.
When the native dialog failed, the popup said "File selector cannot
be displayed. Check nfd library implementation for details." but never
showed any details: NFD_GetError() was never read, so the actual
failure reason (e.g. the xdg-desktop-portal lacking a FileChooser
implementation on the session) was invisible and the user was stuck
without a way to open or save traces.
Capture NFD_GetError() into a static string when
NFD_OpenDialogU8_With()/NFD_SaveDialogU8_With() return NFD_ERROR and
display it in the popup. The copy is required: the returned pointer
references NFD-internal storage (the D-Bus error message or a static
buffer) that is overwritten by the next NFD call or cleared on
shutdown. In TRACY_NO_FILESELECTOR builds no NFD exists, so the
previous fallback line is kept there.
The error is shown as a single line (TextUnformatted) rather than
wrapped: in an AlwaysAutoResize window the wrap width is derived from
the previous frame's window size, which feeds back into the auto-size
and oscillates, converging to a narrow multi-line column for a ~110
character D-Bus message.
When a child group was expanded, the member rows were not visibly
indented under the group name: each row starts at the tree indent
(column 0 is IndentEnable by default, and TableBeginRow() latches the
open group's TreePush indent), so a single Indent() put the label two
IndentSpacing from the cell origin. The group header, however, leads
with the source location color box plus item spacing before its tree
arrow, so its name starts four IndentSpacing further right than the
member labels - the child list read as a continuation of the header
row instead of a subtree.
Add a second Indent() (and the balancing Unindent()) so the member
labels land clearly to the right of the group name. The full-row
Selectable behavior is unchanged. GPU zones are unaffected: their
rows carry no color box, so the member labels were already one level
right of the group name.
The group name-sort key was always the source location name, but
single-member groups display the zone-level name, which prefers the
runtime ZoneName() string. Such groups sorted by a name the user could
not see. The key now mirrors the display: zone name for single-member
groups, source location name for the rest. GPU zones are unaffected
(their names always resolve from the source location).
The child zone list was always sorted by time. It is now a sortable
table with Zone and Time columns, like the statistics view and the
time distribution table in the same window: Time is the default sort
(descending, as before), Zone sorts by name with time as the
tiebreak, and groups plus their members follow the same selection.
The sort choice persists across zones and the group toggle. Group
and child names are looked up once per draw only when name-sorting.
ImGui's CalcWordWrapPosition() only cuts a word mid-word when it fits on
no line, i.e. when it is wider than the full line width. PrintTextWrapped
passes the leftover width for a glued continuation segment's first line,
so a continuation word wider than the leftover (but fitting on the next
full-width line) was being cut mid-word. Detect that case and move the
whole word to the next line instead.
