feat: choose what an extraction does with a name already taken - #355

"Extract archive", Finder's three extract actions and Quick Look's extract button handed the destination itself to the engine. A run that was cancelled, or met a damaged entry, left what it had written by then in the destination, together with the container folder smart extraction had made for it. The engine now writes into a work folder inside the destination, which is moved into place once the extraction has succeeded and removed otherwise. It is on the destination's own volume, so putting the result in place is a rename, and the access the app already holds covers it. The work folder is a placeholder Finder can show: `<archive>.macpack`, declared as a package type so it appears as one item, dimmed the way Finder dims what it is still copying, with the extraction's progress published on it. A finished extraction ends up where it did before: same layout, same container naming, same overwriting of what is already there. What could not be put in place (a file where a folder goes, an item that cannot be written) now fails before anything has moved. "Extract selected" already went through a temp folder; it no longer leaves the empty container folder behind when it does not finish.
… is whole Two points from the review of this pull request. A cancel that arrived as the engine finished was ignored: the engine had nothing left to stop and returned normally, so the result was put in place and the run reported as done. The run is now checked for cancellation before anything of it is committed. Where an extracted file replaces one that sits behind a link on another volume, the old file was removed before the new one had been copied across, so a copy that failed left neither. The new file is now copied beside the old one and takes its place in a single rename.
…lled "Extract to" Two more points from the review of this pull request. Extracting over items that are already there puts the result in place step by step. A step that failed after earlier ones had succeeded left the destination partly updated, and a file already replaced did not come back. Every step can now be taken back, and is when a later one fails: a replaced file changes places with its replacement (or is kept beside itself where the volume cannot do that), and an item that was moved in goes back. Finder's Extract to "name" created its folder before extracting, so a cancelled run left it behind, empty. The extraction now makes that folder itself, and takes it back with a run that does not finish.

Before: when an extracted item had the same name as something already in the destination, Extract archive overwrote it without asking: a file there was deleted for good, and a folder there was extracted into, mixing old and new files (sarensw#140). Extract selected failed halfway: the item could not be moved into place, and whatever had been moved before it stayed. Now: a new setting, Settings ▸ General ▸ "If an item already exists", decides for both: - Keep both (the default): the new item gets a free name next to the old one, which is left untouched: "photo (2).jpg", "photos (2)", the way smart extraction already names its folder. - Replace: what Extract archive did until now. Files are replaced, folders are extracted into, and what is replaced is deleted. - Replace, old one to Trash: the same, but every replaced file goes to the Trash under its own name. Where there is no Trash (a network volume, for instance), it stays next to its replacement under a free name, so nothing is ever lost. Extract selected now places all its items or, if something goes wrong, none of them. With Keep both, Finder's Extract to "name" also gets a free folder name, which fixes the empty result in sarensw#317. Quick Look's own extractions follow the setting too. For review: one routine now places the result for both extractions, ExtractionStaging.place (the commit of sarensw#339, with the choice added). The setting is kept in the app group, like smartExtraction, for the preview to read. Without the setting handed in, Core keeps replacing and ArchiveExtractor keeps both, so nothing loses anything it didn't lose before. Builds on sarensw#339 (ExtractionStaging).

Included review availability: This review used your included allowance. Your plan provides up to 4 included reviews per hour; 1 remain after this review.
Before: this pull request added its changelog items to the 1.1.0 block of Config/products/macpacker.json. 1.1.0 was released on 19 October, so that block takes no new items. Now: macpacker.json is as on main. The full items are in the pull request description, for a new version block, as AGENTS.md asks. The items of sarensw#339, which this builds on, come out too, as they do in sarensw#339.
What & why
Before: when an extracted item had the same name as something already in the destination:
Now: a new setting, Settings ▸ General ▸ "If an item already exists", decides for both:
photo (2).jpg,photos (2), the way smart extraction already names its folder.Extract selected now places all its items or, if something goes wrong, none of them. With Keep both, Finder's Extract to "name" also gets a free folder name, which fixes the empty result in #317. Quick Look's own extractions follow the setting too.
#140 asks for a question per file, as in Total Commander. This is a setting instead, which also suits Finder's actions, where nobody is there to answer; a question could be added later.
Builds on #339 (
ExtractionStaging); until that one is merged, its commits show here too — only the last commit is this one.For review: one routine now places the result for both extractions,
ExtractionStaging.place(the commit of #339, with the choice added). The setting is kept in the app group, likesmartExtraction, so the preview can read it. Without the setting handed in, Core keeps replacing andArchiveExtractorkeeps both, so nothing loses anything it didn't lose before. New strings (settingsNameClash, its three choices and its hint) use the catalog's symbol keys, as since #270.Part of #350.
How it was verified
NameClashTests): free names are numbered before a file's extension and don't collide with each other; a broken link counts as taken; unset means Keep both; Keep both leaves what is there alone; Replace deletes what it replaces; Replace, old one to Trash sends replaced files there under their own names and keeps them when there is no Trash; Extract archive keeps both; Extract selected onto a taken name, which failed before, now does what the setting says (Keep both and Replace).swift test --package-path Modulespasses, all 691 tests; unsigned Release (MacPacker) and Release Store (MacPacker Store) builds, both universal, passscripts/check-architectures.sh.name (2); Replace and Replace, old one to Trash do what they say; Extract selected onto a taken name works.Screenshots — Settings ▸ General before / after ("If an item already exists").
The settings screenshots come from a build with all of these pull requests; this one adds only “If an item already exists”.
