Since #15438, every CLI run that loads a system preset spends about a
second per preset file re-parsing that vendor's entire profile tree. A
slice with a machine, process and filament preset got roughly 2.5 s
slower, and a four-filament slice roughly 4 s slower. This PR loads each
vendor tree once per run instead. Resolved presets and G-code are
unchanged.
The GUI never takes this path, and no release contains #15438, so the
regression only affects CLI runs on current dev and nightly builds. That
includes print farms, slicing services and plugins that call
`orca-slicer --slice`, and CI suites.
## Changes
### Why it was slow
`PresetBundle::resolve_preset_config` resolves a system preset through
its vendor manifest by loading the whole OrcaFilamentLibrary bundle and
the whole vendor tree from JSON, then picking the one preset out. The
CLI did that separately for every `--load-settings` and
`--load-filaments` file, on a fresh `PresetBundle` each time. With BBL
presets, a machine + process + filament run opened `BBL.json` three
times and read BBL's 2,879 profile files and the library's 512 three
times over.
### Load each vendor tree once
- `PresetBundle` keeps every vendor bundle its manifest path loads,
keyed by source root, vendor and substitution rule, and reuses them for
later resolutions on the same bundle.
- OrcaFilamentLibrary is cached the same way, so vendors under one root
share a single library load and the library's own presets resolve from
that same instance. A vendor bundle only reads from its base while
loading, so sharing it is safe.
- A failed or throwing load is not kept, so error reporting is
unchanged.
- The key includes the source root, so presets from two different
profile roots still resolve separately.
- The CLI resolves every system preset through one `PresetBundle` for
the whole run, instead of creating one per file.
The resolved configurations still come from the same canonical vendor
loader, so what a preset resolves to does not change. Only the CLI calls
`resolve_preset_config`, so a long-lived GUI bundle cannot end up
holding profile trees that later change on disk.

CLI slice of a 20 mm cube with X1 Carbon system presets. Both builds get
the same datadir, best of 3, Linux. "Before" is this PR's base from CI.
| System presets loaded | Before | After |
|---|---|---|
| machine | 0.95 s | 0.87 s |
| machine + process | 1.67 s | 0.92 s |
| machine + process + 1 filament | 2.51 s | 0.97 s |
| machine + process + 4 filaments | 5.00 s | 0.99 s |
Files opened during the machine + process + filament run (`strace -e
openat`):
| | Before | After |
|---|---|---|
| `BBL.json` | 3 | 1 |
| `OrcaFilamentLibrary.json` | 3 | 1 |
| `system/BBL/**/*.json` | 8,634 | 2,880 |
| `system/OrcaFilamentLibrary/**/*.json` | 1,536 | 512 |
Peak memory did not rise: max RSS 306 MB → 286 MB for the three-preset
run, and 305 MB → 285 MB for four filaments. The "before" figure is an
AppImage, so part of that gap is probably packaging.
## Tests
<!--
> Please describe the tests that you have conducted to verify the
changes made in this PR.
-->
- New test "Manifest-backed resolution reuses the vendor tree it already
loaded" in `tests/libslic3r/test_preset_bundle_loading.cpp`. It resolves
one preset, changes the parent profile on disk, then resolves a sibling.
The same bundle returns the value it already loaded, and a fresh bundle
picks up the change.
- New test "Manifest-backed resolution shares the library between
vendors under one root". It resolves through one vendor, changes a
library profile on disk, then resolves through a second vendor and a
library preset on the same bundle. Both return the value already loaded,
and a fresh bundle picks up the change.
- All `[Preset][Bundle]` tests pass (87 test cases, 1,069 assertions),
including the existing manifest-backed resolution cases for source-root
scoping, malformed vendor loads, missing parents and type mismatches.
- G-code of the three-preset slice is identical before and after, header
lines excluded.
- The external CLI regression suite passes. Two cases report as
unexpectedly passing because #15639 fixed their bug. They pass the same
way on this PR's base without the change.
- A GUI-vs-CLI parity run over 10 fixtures shows no new differences.
- Builds clean on Linux (Release, with tests).

[How to Download Pull Requests Artifacts for
Testing](https://www.orcaslicer.com/wiki/how_to_download_pr_artifacts)
The manifest resolver loaded OrcaFilamentLibrary once per vendor it
resolved through, so a run that mixes vendors parsed the library tree
again for each of them. The library is now cached like any other vendor
tree, keyed on its root and substitution rule, and doubles as the base
every vendor under that root loads against. A vendor bundle only reads
from its base while loading, so sharing the instance is safe.
The cache key carries the substitution rule as its enum, and the lookup
lambdas take a const bundle since they only read.
`--export-settings` already writes the merged config as JSON at the
right point in the CLI flow. Passing `-` now writes that same document
to stdout, so scripts can inspect the effective config without a temp
file. This replaces #14605.
- `ConfigBase::save_to_json` gains a stream overload. The file overload
serializes through it before opening the file, so the output format is
unchanged, and a config that cannot be serialized (invalid UTF-8) now
leaves the existing file untouched instead of truncating it.
- On stdout, invalid UTF-8 in string values is written as U+FFFD instead
of ending the process with an uncaught `type_error`. Files keep the
strict behaviour.
- To keep stdout pure JSON, `-` is rejected up front (stderr message,
`CLI_INVALID_PARAMS`, shell status 254) when combined with an action or
transform that can write to stdout or does real work: `--info`,
`--help`, `--orient`, slicing and exporting. Options that do nothing
without a slice (`--uptodate`, `--min-save`, `--pipe`, ...) are still
accepted.
- The one unconditional stdout write on a success path, "skip locked
instance" during arrange, now goes to the log.
- Every other value, including the default `output.json`, behaves as
before.
Tests in `tests/libslic3r/test_config.cpp`: the stream output equals the
file output and keeps the tab-indented format; invalid UTF-8 throws on
the strict path and is replaced when asked; a failed save leaves the
previous file intact.
Opening a model with a relative path, for example `orca-slicer ./some.3mf`,
failed with "Loading of a model file failed." and "The file does not contain
any geometry data.", while the same file opened by an absolute path or by
drag and drop worked.
GUI_App::init_app_config() changes the working directory to <data_dir>/log,
and it runs from the GUI_App constructor because the app config is needed
early for instance checking. The input files are opened much later, in
post_init(), so a path still relative at that point resolved against the log
directory instead of the directory OrcaSlicer was started from, and the 3MF
reader failed to open it.
Resolve the input paths in CLI::setup(), which runs before GUI_App is
constructed and therefore before the working directory moves. Absolute paths
are returned unchanged, so the forms that open today are unaffected, and
custom open protocol URLs are passed through since post_init() hands those to
the downloader rather than the file loader.
The working directory change is left alone. It was added in #3248 so the TUTK
logs land in the data directory instead of the working directory (#3209).
--export-settings already writes the merged config as JSON at the right
point in the CLI flow. Passing - writes the same document to stdout.
- ConfigBase::save_to_json gains a stream overload. The file overload
serializes through it before opening the file, so the format is
unchanged and a config that cannot be serialized leaves an existing
file untouched instead of truncating it.
- On stdout, invalid UTF-8 in string values is written as U+FFFD instead
of ending the process with an uncaught type_error; files keep the
strict behaviour.
- - is rejected up front when combined with an action or transform that
can write to stdout or does real work, so stdout carries only the
JSON.
- The unconditional "skip locked instance" stdout write during arrange
now goes to the log.
- Tests in tests/libslic3r/test_config.cpp.
* Extract Layer::choose_ironing_extruder for unit-testable ironing routing
The ironing extruder selection in make_ironing() was a 5-line nested
conditional inlined at the top of the loop, with no isolated test
coverage. Pull the gating into a static helper so the routing decision
is unit-testable without spinning up the slicing pipeline.
Pure refactor: the helper preserves the original logic bit-for-bit
(NoIroning -> -1; AllSolid always enabled; TopSurfaces and TopmostOnly
require some top shells or, in spiral mode, more than one bottom shell;
TopmostOnly additionally requires being on the topmost layer; enabled
ironing routes to solid_infill_filament).
Add tests/fff_print/test_choose_ironing_extruder.cpp covering:
- AllSolid regardless of layer position
- TopSurfaces with top_shell_layers > 0
- TopSurfaces with top_shell_layers=0 + spiral mode + bottom_shell_layers>1
- TopmostOnly + topmost layer
- NoIroning short-circuit
- TopSurfaces with top_shell_layers=0 (and not spiral) -> disabled
- TopSurfaces, spiral, but bottom_shell_layers=1 -> disabled
- TopmostOnly on a non-topmost layer -> disabled
* Move ironing routing test into the Fill subsystem file
Rename the test to tests/libslic3r/test_fill.cpp and tag it [Fill] to
match the subsystem it covers, use flat behavioral test cases with
GENERATE for the parameterized ones, and drop the history narration from
the code comments.
* tests: move ironing routing tests into fff_print/test_fill.cpp
Keeps the Fill tests in one file, alongside the existing ironing
rotation-template test.
Resolving a system preset through its vendor manifest loaded the whole vendor tree and the filament library from JSON, and the CLI did that separately for every --load-settings and --load-filaments file. A run with machine, process and filament presets parsed BBL's 2,879 profile files and the library's 512 three times over, about a second each.
Keep the library and vendor bundles loaded by the manifest path on the PresetBundle that resolved them, keyed by source root, vendor and substitution rule, and have the CLI resolve every system preset through one bundle for the whole run. A failed load is not kept, so errors are reported as before.
On a cube slice with X1C machine, process and PLA presets: 2.42 s -> 0.93 s, BBL.json opened once instead of three times, identical G-code.
A valid mixed filament already slices the same on the CLI as in the GUI;
these are the places where the CLI still skipped a rule the GUI applies.
- Keep the prime tower when a mixed filament is used, even if every
--load-filaments preset is the same. A mixed filament swaps between its
components every layer, so turning the tower off left the swaps with
nothing to purge on.
- Leave a mixed slot's row and column of the flush matrix at zero when
--filament-colour triggers a recompute, as the GUI does; a mixed slot
never reaches a nozzle.
- Refuse a mixed slot that has no filament of its own. Feature filament
ids aimed at it were past the filament count, got reset to filament 1
and the model silently printed in one colour.
- Refuse a plate that uses a mixed filament whose components are
different filament types, the type half of the GUI's
Sidebar::has_broken_mixed_filament. Missing or out-of-range components
are already rejected for the whole project by validate().
get_extruders_under_cli gains an expand_mixed_slots flag so the gate
can see mixed slots rather than their components; existing callers
keep the expanded list.
Both refusals exit with the new CLI_MIXED_FILAMENT_INVALID (-69).
update_values_to_printer_extruders_for_multiple_filaments picks each
filament's value from the flattened (filament x variant) columns of every
per-filament variant option. When a column index fell past the end of the
option's values, it skipped that filament and left the zero the output
vector was created with.
The GUI always hands this function full columns, but the CLI does not:
- a CLI override of a single value, such as --nozzle-temperature=211 on a
four-filament project, came out as 211,0,0,0, so three filaments would
print at 0 C;
- loading fewer filament presets than the project has filaments left the
remaining filaments' columns missing, so filament_cooling_before_tower
came out as 10,10,0,0 and filament_ramming_volumetric_speed as -1,-1,0,0.
An out-of-range column now keeps the option's first value, the fallback
get_at() and the sibling gather step already use. The seven per-type copies
of the loop are replaced by that same gather_option_values helper, moved
above the function; it now takes its caller's name for its log lines. An
empty option, which has no first value, is given one registered default per
filament first; it used to be replaced with zeros.
On a partial load a filament whose preset was not loaded takes the first
filament's value rather than its own preset's, which the CLI does not load;
for the options seen in practice those agree.
* CLI: record command-line overrides in different_settings_to_system
Settings passed on the command line (--sparse-infill-density 25% ...) override
the loaded presets when m_extra_config is applied to m_print_config, but nothing
recorded them in different_settings_to_system. The exported project therefore
carried the new value with no mark that it was modified, and re-opening it in the
GUI reverted it to the system preset's value -- the same failure the preset-leaf
diff fixes for user presets, via a different source of override.
The key set comes from m_config, not m_extra_config. read_cli() puts only what the
user typed into m_config and setup() adds nothing but CLI-own defaults (none of
the keys run() materialises there is a preset option), whereas the CLI writes its
own values into m_extra_config (has_filament_switcher, filament_colour,
filament_map ...), which must not be reported as user overrides.
Values are snapshotted just before the apply and only keys the override actually
changed are recorded: a typed value equal to the loaded one modifies nothing, and
listing it would read as a spurious difference against what the GUI writes. Each
key lands in the column(s) whose preset type owns it -- process, every filament,
printer -- and a key already present is not duplicated. Keys no preset owns
(curr_bed_type, a project setting) land nowhere, as in the GUI.
Follow-up to #15595, split out at review.
* CLI: judge command-line overrides the way the value is read
Review follow-ups on the override recording:
- Lists were compared as whole serialized strings. read_cli() builds a fresh
one-entry list, so --nozzle-temperature 245 against 245,245,245 on a
three-filament project was recorded in every filament column although nothing
changed. Lists are now compared entry by entry with a missing entry read as the
first, as get_at() reads it (and as resize() pads).
- The log line fired for every changed key, including ones no preset owns
(curr_bed_type) and which therefore land in no column. It now fires only when a
column took the key.
- m_print_config.has(key) straight after apply(m_extra_config, true) was always
true, both configs sharing print_config_def; removed. columns.size() >= 2 also
always holds after the resize to filament_count + 2 -- different_settings_to_system
is not a CLI option, so nothing in between can shrink it -- but that rests on code
far away, so it stays a plain check rather than an assert: release builds compile
asserts out, and a _GLIBCXX_ASSERTIONS build would abort on columns[0].
Deliberately NOT done: comparing a key the loaded config lacks against its
built-in default. On reopen the GUI restores an unlisted key from the SYSTEM
preset, not the default. A 3MF written before an option existed leaves it absent
here, so --sparse-infill-density 20% (the default) against a Prusa system 15% would
go unrecorded and be reverted to 15%. Absent keys stay always-recorded:
over-recording is cosmetic, under-recording loses the value. Verified that such a
key really is absent at this point, rather than filled from the system preset.
Reported by HanifKoh and raistlin7447 in review of #15642.
* CLI: evaluate compatible_printers_condition in the compat checks
Slicing from the CLI with --load-settings exits with
CLI_PROCESS_NOT_COMPATIBLE (-17), "The selected printer is not compatible
with the process preset in the 3mf.", for process/printer pairs the GUI
accepts. Reproducible with stock, unmodified Prusa system profiles:
orca-slicer --datadir <datadir> \
--load-settings "<datadir>/system/Prusa/process/0.20mm SPEED @CORE One HF 0.4.json;<datadir>/system/Prusa/machine/Prusa CORE One HF 0.4 nozzle.json" \
--load-filaments "<datadir>/system/Prusa/filament/Prusament PETG @CORE One HF 0.4.json" \
--slice 0 --outputdir /tmp/out model.stl
The four compat checks in CLI::run did a literal name match against the
`compatible_printers` list only:
for (index ...) if (new_print_compatible_printers[index] == new_printer_system_name)
process_compatible = true;
Process profiles that declare compatibility through
`compatible_printers_condition` and leave `compatible_printers` empty are
therefore always reported incompatible -- the condition is never consulted.
For 0.20mm SPEED @CORE One HF 0.4 that condition is:
printer_notes=~/.*PRINTER_MODEL_COREONE[^_a-zA-Z0-9].*/ and
nozzle_diameter[0]==0.4 and printer_notes=~/.*HF_NOZZLE.*/
The GUI does not have this bug: is_compatible_with_printer() in Preset.cpp
treats an empty list as "no explicit constraint" and evaluates the
condition in that case.
Fix: replace the four loops with a check_compat lambda that calls
is_compatible_with_printer() -- the same helper the GUI uses -- wrapping
the already-loaded DynamicPrintConfigs in lightweight Preset /
PresetWithVendorProfile shells. The 3MF-embedded process/printer full
configs are kept in current_process_full_config /
current_printer_full_config so the condition can be evaluated for the
reprocess paths too; those fall back to the previous literal match when
the full config was not preserved.
Behaviour is unchanged where an explicit compatible_printers list exists:
is_compatible_with_printer() performs the same name match, and returns
true when both list and condition are empty, matching the existing
"old 3mf, no compatible printers, set to compatible" path.
Split out of #13731 (section 1) as a standalone, single-purpose change.
Orthogonal to the inherits-chain resolution work in #14718 / #15302 /
#15438; those decide which values a preset resolves to, this decides
whether the resulting pair is considered compatible.
* CLI: translate the 3MF's renamed compatibility keys before the compat check
The 3MF fallback fed the project config to is_compatible_with_printer() as-is,
but a project config does not carry compatible_printers or
compatible_printers_condition. PresetBundle::construct_full_config() erases both
and re-emits them as print_compatible_printers and
compatible_machine_expression_group; they are renamed back only on the
PresetBundle load path, which the CLI does not take. The check therefore saw no
list and no condition, read that as 'no constraint' and accepted every printer.
That is not just a wrong accept. An early true skips the !process_compatible
block that sets machine_switch, so the new printer is never appended to
print_compatible_printers and the exported 3MF stays marked compatible only with
the printer it came from -- which is exactly what that block exists to prevent.
Translate the two keys back before the check. Index 0 of the expression group is
the print preset; the group is filled print, filaments, printer.
Also note in the comment that profiles/BBL/{process,machine}_full/ are gitignored
and generated by nothing in-tree, so current_*_full_config is always empty and
this fallback is the only live path -- not the rare non-BBL case the original
comment implied.
Reported with measurements by HanifKoh in review of #15449.
Preset: add a config-level is_compatible_with_printer() overload
The CLI holds resolved DynamicPrintConfigs, not Presets, so it wrapped them in
throwaway Preset shells at the call site. Moving that into Preset.cpp puts the
compatibility policy -- including the documented fail-open on a malformed
compatible_printers_condition -- in one place for the GUI and the CLI, rather
than leaving a second copy of the plumbing in OrcaSlicer.cpp to drift.
Purely additive: neither existing overload changes, so no GUI behaviour moves.
Requested by HanifKoh in review of #15449.
(cherry picked from commit 14ca1972ef4d3c7d90935d159423013a40a6bd70)
* CLI: never overwrite a real compat key with an empty renamed one
7e7f0e3 translated compatible_machine_expression_group[0] into
compatible_printers_condition whenever the group vector was non-empty. A project
the CLI exported itself carries the real compatible_printers_condition AND an
all-empty group, ["", "", ""], so the valid condition was overwritten with
"", the check saw no constraint, and every printer was accepted.
That fixed GUI-shaped projects and broke CLI-shaped ones. Bisected across six
builds re-slicing one CLI-exported CORE One project with an MK4S: every build
before 7e7f0e3 gives 'compatible 0' and takes the machine-switch path; with it,
'compatible 1' and no switch.
The raw keys now win whenever they carry something; the renamed ones are only a
fallback, and an empty value is never written over a real one. Same for the list:
print_compatible_printers is used only when compatible_printers is absent or
empty and it itself is not.
Found by a peer session re-testing the installed build.
* CLI: record user overrides in different_settings_to_system for 3MF export
Three sites in CLI::run wrote an empty `different_settings_to_system` column
and left a //todo:
//todo: support user machine preset's different settings
different_settings[filament_count+1] = "";
//todo: support system process preset
different_settings[0] = "";
//todo: update different settings of filaments
different_settings[filament_index] = "";
So a 3MF exported by the CLI does not record which keys the user actually
overrode relative to the system parent. Re-opening such a project in the GUI
then shows spurious "unsaved changes", and accepting that dialog can revert
inherited process/filament/machine values to system defaults.
The column could not be filled before because the CLI had no resolved view of
the parent preset. It does now: #15438 builds a PresetBundle for inherits
resolution, so the parent can be looked up by name and diffed against the
resolved leaf. This adds no extra loading -- the bundle is the one already
built, and the helper returns "" whenever it is unavailable or the parent
cannot be found, which is the previous behaviour.
Preset metadata is filtered out of the diff: `inherits`, the three
`*_settings_id` keys, and `compatible_printers` / `compatible_prints` and
their `_condition` variants, which have their own tracking columns
(`inherits_group`, per-slot lists) and would otherwise double-count.
A value already carried by the loaded JSON still wins for the process slot, so
presets saved with a `different_settings_to_system` field behave as before;
the computed value only fills the gap where that field is absent, which is the
case for every user preset in my datadir (0 of 47 carry it).
System presets keep an empty column: there are no user overrides to record.
* CLI: diff the filament slot before load_default_gcodes_to_config
The process and machine slots compute their different_settings_to_system column
before load_default_gcodes_to_config(); the filament slot did it after. That
call materialises absent gcode keys via option(..., true), and
DynamicConfig::diff only compares keys present in both configs -- so a gcode key
the resolved leaf did not carry would go from 'not compared' to 'compared as
empty against the parent' and land in the column as an override the user never
made.
Hoisted into a local above the call, guarded by load_filament_count > 0 so the
work is skipped exactly where it was before, and assigned at the original site.
The diff now also runs before config.erase("filament_settings_id"), which is
immaterial: cli_different_settings already filters filament_settings_id along
with the other *_settings_id keys.
This is a consistency fix rather than a demonstrated defect -- resolve_preset
merges the parent config, so in practice the gcode keys are already present on
both sides and the diff is unaffected. It removes the dependence on that
invariant, which the other two slots never had.
Reported by HanifKoh in review of #15595.
A build without SLIC3R_PCH had never been tried on macOS. Three files
used what pchheader.hpp happened to include: LocalesUtils.cpp needs
<sstream> and <iomanip>, and the two dialogs need <wx/tooltip.h>. The
GTK port's headers and libstdc++ pull these in transitively, the Cocoa
port's headers and libc++ do not.
# Description
Each plate keeps a registry of the instances it holds
(`PartPlate::obj_to_instance_set`). The plate's filament list
(`get_extruders`), its wipe tower preview and position clamp, the object
list grouping and the saved project's per-plate instance list all read
it. Two paths left it stale:
* `Plater::increase_instances` (the `+` key / toolbar) adds the copy to
the model but never registers it with any plate.
* `GLCanvas3D::do_move` (drag release and arrow keys) ended with
`notify_instance_update(-1, 0)`, so only instance 0 of each selected
object was re-registered. Rotate, scale and mirror already notify every
instance.
So a copy created with `+` and dragged onto another plate stayed unknown
to that plate: the project saved afterwards listed it on no plate, and a
multi-filament copy moved onto a single-filament plate drew no wipe
tower there and never got its tower position clamped. The Print side
selects instances by geometry, so the plate still sliced, which is why
this went unnoticed.
This PR
* registers new copies with their plate at creation;
* has `do_move` notify exactly the instances it moved (every instance of
the object when a part was moved in Volume mode), rather than instance 0
or all instances - notifying an instance that stayed put invalidates its
plate's slice result, so `(-1, -1)` as used by rotate would have
un-sliced every plate holding a sibling copy;
* drops the registry entry again when `decrease_instances` removes a
copy.
A second commit finishes the switch #15532 started with
`contain_any_instance_totally()`: `get_extruders_without_support()`,
`check_single_extruder_mixed_filament_risk()` and
`check_compatible_of_nozzle_and_filament()` still tested instance 0
only, so an object whose copy - not its original - sits on the plate was
skipped by all three.
No new options, no format change. The `is_new` flag is deliberately not
passed for the copies: a copy landing on a spiral-vase plate gets the
same "apply spiral mode settings?" prompt a dragged instance gets,
instead of a silent rewrite of the object's settings.

## Tests
Re-run after the rebase, both binaries driven through the same headless
harness (Xvfb 1920x1080, llvmpipe) on the same fixture: `cubeA`
(filament 1) alone on plate 1, `cubeB` (a two-part object, filaments 2
and 1) alone on plate 2, so plate 1 shows no wipe tower at load. Select
the plate-2 object, press `+`, walk the copy onto plate 1 with 36 x Left
(10 mm per press, one `do_move` each), save, slice plate 1.
Before is main `8af92214d0` - i.e. with #15532's
`contain_any_instance_totally()` already in place, so the only
difference is this PR.
* **Before:** the saved `model_settings.config` lists plate 1 with
`cubeA` only and plate 2 with `cubeB` instance 0. The copy (instance 1)
is listed **on no plate at all**, and plate 1 draws no wipe tower even
though a two-filament object is sitting on it.
* **After:** plate 1 lists `cubeA` **and** `cubeB` instance 1; plate 2
still lists instance 0. The plate-1 tower preview appears, and slicing
plate 1 succeeds with the tower actually generated - the filament panel
reports 1.10 m / 0.48 m in its Tower column over 51 filament changes,
and the G-code carries `EXCLUDE_OBJECT_END NAME=cubeB.stl_id_1_copy_0`.
Same camera and fixture on both runs, so the screenshots above are
directly comparable.
* Fix internal bridges over Hilbert Curve/Octagram Spiral sparse infill

produced noise across all turning directions (0/90/180/270°)
instead of a single dominant one, yielding unstable bridge angles
with 180° spread. Fix: use the configured infill_direction + 90°
directly, bypassing the noisy sampling. The old blind +0.25*PI
(Hilbert) and +1/16*PI (Octagram) offsets are removed.
2. construct_anchored_polygon: curved Hilbert/Octagram anchors
intersected each vertical scan line many times at wildly different
Y positions, producing chaotic polygon sections — holes in random
places, bridges over air, rotated bridges. Fix: replace the curved
infill polylines with synthetic straight lines parallel to
infill_direction, spaced at the real infill line spacing
(flow_spacing / density). Lines are centered on the limiting_area
bbox center so that after rotation they span the full bridged_area.
Anchors are left at full bbox length (not clipped) to guarantee
every scan line finds an anchor.
Rectilinear and other straight-line patterns are unaffected.
Known limitation: some bridge edges may still terminate over air in
edge cases where the nearest synthetic anchor line is more than one
infill spacing away from the bridge boundary. This will be addressed
in a follow-up.
* fix: anchor internal bridges to actual sparse infill
Preserve real anchors across regions and align plane-path anchor origins with printed infill. Respect lower-layer rotation templates and model alignment, and sample curved bridge boundaries more finely.
Add regression coverage for anchor alignment, bridge angles and region isolation, with Orca comments explaining the geometry constraints. Verified 175 FFF tests before the comment-only follow-up; preserve CRLF in modified files.
* Fix internal bridge support contacts and separated infill origins
Restore anchor contact after bridge smoothing and share per-body pattern origins between anchors and printed infill. Recompute origins when preparation settings change.
Cover multiline counts 1, 2 and 3 and add regressions for printed bridge support, separated infill alignment and reslicing.
* Add explicit standard headers to PrintObject tests
* test: cover surface centering when infill settings change
Verify top and bottom Archimedean Chords and Octagram Spiral paths after switching centering modes or toggling separated infills. Compare reslicing against fresh slicing and document dependent infill invalidation.
* test: preserve directional surface infill when settings change
* perf: index layer islands for connected-body detection
* test: use public print pipeline for body centering checks
* build: clear 2 warnings - cast the NSTextField the class check already proved
mainframe_text_field is NSTextField* and was assigned a bare NSView*, which
Clang reports as -Wincompatible-pointer-types. Both assignments sit inside
if ([viewObject class] == [NSTextField self]), so the runtime type is already
guaranteed, and the line above the second one casts the same variable the same
way to call setTextColor. macOS only, since nothing else compiles this file.
* build: clear 6 warning categories from the clang-cl inventory
-Wmissing-braces (9). Aggregates whose first member is itself an aggregate.
GUID's fourth member is BYTE[8], so the trailing eight bytes take their own
braces. The others were reaching for zero-initialization with {0} and say {}
now. bbs_3mf's backup Task ends in an anonymous union, which needs braces of
its own; those braces initialize the union's first member rather than the one
named at the call site, so the RemoveBackup site says so in a comment.
-Wmacro-redefined (11). SendMultiMachinePage.hpp defines five names that
Preferences.hpp, PresetBundleDialog.hpp, ExportPresetBundleDialog.hpp and
TroubleshootDialog.hpp also define with different values, so the value in
force depended on include order. All nine of this file's DESIGN_ macros take
the SEND_ prefix it already uses for its own macros, values unchanged, so a
DESIGN_ name added elsewhere later cannot collide with it again. They read as
one page-local palette, a 900 to 400 gray ramp plus sizes, so the four with
no current readers stay: dropping them would leave gaps in a named scale. test_marchingsquares.cpp defines NOMINMAX,
which libslic3r already passes as a PUBLIC compile definition, so it takes
the #ifndef guard the other suites use.
-Wbraced-scalar-init (3). Two PushStyleVar calls resolve to the float
overload, so the braces were initializing a scalar. ConfigOptionFloatsNullable
already takes an initializer_list, so the inner braces did the same thing.
-Wmicrosoft-goto (2). Both gotos in copy_file_gui jump forward over the
initialization of size, dwRead and dwWrite, which only MSVC accepts. Those
declarations move up to join the others at the top of the function.
-Wunused-private-field (3). Every use of ColourPicker's m_clrData and
m_picker_widget is behind !defined(__linux__), so on Linux they are written
and never read; the members now carry the same guard. ParamsPanel's
m_size_move is read nowhere. Tab has its own, which is the one Tab.cpp uses.
-Wnonportable-include-path (2). BaseException.h asked for "stackwalker.h"
and the file on disk is StackWalker.h.
get_extruders() and estimate_wipe_tower_size() already ask whether any
instance of an object sits on the plate; the support-less extruder scan, the
mixed-filament risk check and the nozzle/filament compatibility check still
tested instance 0 only, so an object whose copy - not its original - was
placed on the plate was skipped by all three.
An instance added with "+" was never registered with the plate it landed on,
and moving an instance only re-registered instance 0 of its object, so a copy
dragged onto another plate stayed unknown to that plate's registry. The
plate's filament list, its wipe tower preview and the position clamp all read
that registry, so a multi-filament copy moved onto a single-filament plate
drew no tower there and its tower position was never clamped.
Register new copies at creation, notify exactly the instances a move changed
(every instance of the object when one of its parts moved), and drop the
registry entry when a copy is removed again.
build: clear eleven single-site clang-cl warning categories
Each of these is the last site left in its category, and every one is the
compiler saying it cannot tell what the code meant. Nothing here changes
defined behavior.
- OrcaSlicer_app_msvc.cpp printed a DWORD with %d
- StackWalker.cpp ran delete[] through an LPVOID
- ToolOrdering.cpp used a bare ; as a deliberate skip loop's body
- WipeTower.cpp had finish_block_tcr = finish_block_tcr, so the branch that
reached it did nothing. Folding the condition into the enclosing if leaves
the other branch untouched
- GCodeProcessor.cpp had an else binding to the inner if while the outer if
carried no braces
- AmsMappingPopupUpdate.cpp wrote >= 1 || <= 3 where its own comment says &&
- CalibrationWizardPresetPage.cpp left max_decimal_length unset through a
pair of conditions that cover every value but not visibly so
- DevManager.cpp bound map elements to pair<K, V> rather than
pair<const K, V>, copying every one
- SyncAmsInfoDialog.cpp had extraneous parentheses around a comparison
- Http.cpp had if (speed > 0.01) speed = speed;. speed now starts at 0 as
well, because curl_easy_getinfo leaves the target untouched when it fails
and the value reaches Progress either way
- SnapmakerPrinterAgent.cpp truncated npos into an unsigned int, so the
!= npos guard was always true. A colour with no # still yields 0, because
the wrap produced 0 as well
Nine categories go to zero. -Wtautological-overlap-compare and
-Wsometimes-uninitialized reach zero when #15583 merges their second site.
