Lock Config and Preset Files Across Instances and Write Them Atomically
Every running instance shares one OrcaSlicer.conf and one user preset tree, and nothing kept their writers apart. Two instances saving at the same moment, or the cloud preset sync thread writing while the GUI thread saved, could interleave, and a reader in another instance could open a preset JSON or .info file between truncate and close and get a partial file, dropping that preset for the session with a parse error. Add InstanceLock, a scoped guard that serialises the threads of one process through a recursive mutex and other processes through an advisory OS file lock: flock on POSIX, held on the guard's own descriptor so no other close in the process can drop it, and LockFileEx on Windows. The outermost guard opens the lock file and closes it on release, so nothing stays open between saves and a data dir can be removed once nothing is saving into it; the file itself is kept, since deleting it would let a third instance lock a fresh file while the second still holds the old one. It is best effort: when the lock file cannot be opened or locked, or another instance still holds it after a second, the guard logs once and lets the write proceed, then leaves the file alone for ten seconds, so a hung instance never blocks every other one and a holder stuck in a debugger does not cost a stall per save. The guard sits at the leaf readers and writers: set_sync_info_and_save() calls save_info() under the preset collection mutex, so a batch lock around save_user_presets() would invert the order against the sync thread. The preset scan re-takes the guard every 32 files rather than holding it across the scan, and a bundle or user folder is renamed into cache/ under the lock and removed outside it, so a save never waits for a whole tree. Read-only scans, which is what the CLI does, take no lock and create no lock file. AppConfig holds OrcaSlicer.conf.lock in load() and save(); load is included because the Windows path restores from the .bak copy. Every user preset writer and reader holds user.lock: Preset::save(), which writes no .info when the preset itself could not be written, since an .info without its preset reads as a cloud deletion request, save_info(), reload() and remove_files(), each file read by the preset scan, the bundle metadata reads and write, the .info removal after a cloud-confirmed delete, the orphaned-.info scan on the sync thread, the bundle folder removal on unsubscribe and the physical printer writers and delete paths. A bundle import extracts under cache/ into a folder per process and per import, where no scan reads. Preset JSON, .info, bundle metadata, physical printer and config files, and the caches and state files that already used a temporary by hand, now go through write_file_atomically(), which writes <file>.<pid>.<n>.tmp beside the target and renames it over, so a reader that never waits sees a complete old or new file. A target this process may not write is refused before anything is written, unless the caller says the file was always replaced, as the config was; a symlink is followed; a target that is not a regular file is written in place; and when the rename itself is refused, by a Windows reader holding the file open or a mount that cannot replace in one step, the helper writes in place as before, since losing the save is worse than a torn read. On POSIX the rename replaces the target atomically where the old code removed it first and left a window with no file at all; only a mount that refuses a one-step replace gets the old remove-then-rename. A crash between temporary and rename leaves the temporary, which the scans of the directories the application owns remove once it is an hour old; only the exact shapes this code writes qualify, so a user's numbered backup or an export folder is never touched. A failed config write keeps the config dirty, and the idle handler waits ten seconds before retrying while an explicit save always tries. |

Cache system presets to eliminate startup and wizard load times (#14217)
* Add caching system for presets * Removing user\bundle serialization and keeping it only for system presets * Integrate caching into WebGuideDialog which speeds up time of SetupWizzard and PrinterSelection dialog * Add CI\CD step to prepare cache file in ahead of time so user does not need to wait * Add partial cache generation when only one of the vendros is changed to speed up recalculation time * Handle corrupted files * Add cache to GuideDialog as previos version didn't work as expected * Add inspecting tool and fix CI cache generation * Generate cache per vendor * Simplify code by mergin it in PresetBundle * Simplify code a bit more * Add cereal serialize() to VendorProfile, PrinterModel, Preset, and Semver * Remove CachedPrinterModel/VendorProfile/Preset mirror structs from VendorCache * Fix use-after-free in CallAfter lambda; replace raw thread pointer with unique_ptr * Use get_vendor_cache_key() to match cache keys written by the app * Remove BOM added by VSC * Skip invalid vendors * Remove leftover cache file * Fix build for windows arm64 * Revert json cache back * Update check for stale cache * Serealize all value fields for Preset class to minimize regression later * Minimize field duplication by moving Cache thing into PresetBundle * Add tests for Cache system * Add a bit more tests * Merge branch 'main' into feature/cache_profiles_and_optimize_loading_speed * Rvert from per-verndor to single cache file Replace N per-vendor .cache files with a single system_presets.cache that holds all vendors and presets in one serialized blob. Cache load is now all-or-nothing: on hit all vendors are applied from the bundle (sub-second); on miss all vendors are parsed from JSON and a fresh bundle is written to the user cache dir. Invalidation is driven by bundle_key - a sorted concatenation of all vendor JSON version strings. Any vendor update invalidates the whole cache and triggers re-parse on next launch. Guide wizard (WebGuideDialog) loads the bundled cache into a plain PresetBundle instead of a separate VendorGuideData struct, removing the duplicate data model. generate_system_cache simplified from a per-vendor loop to a single save_system_presets_cache() call producing one output file. * Transfer all Preset fields from cache via move assignmet apply_vendor_preset_group was copying fields manually and missed bundle_id, user_id, base_id, sync_info, updated_time, key_values, ini_str. Replace field-by-field copy with move assignment of the fully-deserialized Preset, then restore the vendor pointer which is excluded from serialization. * Ignore cache for future * Remove not used files * Ship one preset cache per vendor in place of the profile JSONs Each vendor's system presets serialize into a single <vendor>.opc built at package time, and a shipped build carries that file alone — the profile JSON and its sub-file tree are pruned. The vendor loader, the setup wizard's profile list and the resource installer all read a vendor through its cache, falling back to parsing whenever one is absent, stale or unreadable, so the cache stays an optimization and never a source of truth. Caches hold presets in source form and resolve inheritance at load, through the same code the JSON path uses. * Make the preset cache self-describing and load each vendor from the system folder alone The cached DynamicPrintConfig is keyed by name, through a per-file dictionary of the distinct opt_keys, the type each was written as, and the distinct enum value names, instead of by serialization_key_ordinal — a position assigned by declaration order at static init, where inserting one option shifts every later ordinal and the lookup then succeeds on the wrong option. Because a name-keyed payload drops the options this build cannot place rather than being rejected wholesale, the schema fingerprint goes, and with it the two fallbacks that existed only because an installed cache died on every app upgrade: the second lookup tier into resources/profiles and the parse fallback to the same place. A vendor is loaded from <data_dir>/system/ and nowhere else, as on main — which is what makes the app write its .opc files there again. * Simplify the preset cache internals after review * Use the shared temp-dir helper in the preset bundle loading test * Bound stamp string reads in the preset cache * Speed up the setup wizard with a profile-data cache The wizard's per-vendor fast path threw on vendors present only in resources, falling back to a ~29 s raw JSON scan on every open. Each vendor now loads from the directory it was found in, and the derived model/machine/filament/process catalog is cached whole in <data_dir>/cache/wizard_profile_data.json, stamped by each vendor's name and version - a fresh cache makes an open one file read, with no bundle built and no presets installed (~0.2 s vs ~2 s). * Remove debug SVG dump from a geometry test * Move the per-vendor cache file format into PresetCacheFormat * Move the vendor install helpers from PresetBundle into Utils * rename * fix flatpak * change cache version to 1 --------- Co-authored-by: SoftFever <softfeverever@gmail.com> |
