Saving replaced the project file with nothing kept of what it was: one
bad save -- a fault in QElectroTech, a full disk, a wrong edit saved by
mistake -- and the last good version was gone. AutoCAD keeps a .bak on
every save, KiCad several backups.
Before a project is saved over, the file as it was is now copied to a
folder beside it, "<name>-backups", named by the time that version was
saved ("industrial 2026-10-16 08-30-12.qetz"); only the newest are kept,
5 by default (Settings > General > Projects, 0 for none). A copy is
never a move, so a save that fails leaves the file in place; a copy that
fails only warns, the save goes on. The same bytes as the newest version
kept are not kept twice.
The prompt on opening ("Create a backup copy?"), which writes one dated
copy beside the project and never removes any, is left as it is.
New tst_previousversions (newest kept, same bytes once, same second,
nothing for a new file or a count of 0, a failed copy said); it fails
with the oldest never removed. Checked with the program: two scripted
saves of a .qetz leave the original and the first save in
industrial-backups, the project holds the second. ctest 107/107.

A .qetz's project.sqlite comes from a file, which may be damaged, made
by another tool, edited by hand (issue #1458) or made to harm. SQLite's
advice for such files (https://www.sqlite.org/security.html) was only
partly followed: trusted_schema was off and every name had to be a plain
table. readAsUntrusted() now also turns on the defensive mode, turns off
triggers and views, checks each cell's size as its page is read, limits
a value to 256 MiB, and runs quick_check before anything is read, for
the database read on opening and for the one a save copies kept folios
from.
A damaged database is now refused as "the project database is damaged",
where it was "cannot be read: database disk image is malformed" or a
missing row. Damage on disk was already caught before SQLite: the zip
checks each entry (one flipped bit in project.sqlite: refused, "unexpected
decompressed size"). quick_check does not see a changed value inside a
row (49 of 400 random small changes read silently, quick_check "ok"):
only the zip's checksum does.
New test damagedDatabaseRefused (a page overwritten at three places):
fails without this change on the message. Opening nuri (136 folios):
3.56-3.66 s with and without. ctest: the 7 container, save and lazy
folio suites pass.

QSaveFile writes a new file, forces it to disk and renames it over the
old one, but does not force the folder to disk. On ext4 or XFS a power
cut soon after a save can then lose the rename: the previous file comes
back, or none. QET::syncFolderOf() now syncs the folder after every
project, symbol and title block save (QET::writeXmlText()) and every
.qetz save (QetZip::write()). Nothing to do on Windows.
--resave and --set-titleblock wrote a .qet straight over the output file
(QFile, truncate, write): a run stopped part-way left half a project.
They now write through QET::writeXmlText() like the GUI's save. On
Windows their .qet now has LF line ends, as the GUI writes.
Checked with strace on --resave: fdatasync of the new file, linkat into
place, fsync of the folder. The .qet written is byte-identical to before.
ctest 106/106.

- Implement ElementTextFormatPattern to capture and reapply dynamic element text formats (font, color, alignment, rotation, frame, positions, groups) across elements.
- When applying a format, missing ElementInfo texts present on the source template are added to the target element with the template's layout and styling, matching other texts in order.
- Register actions under Edit menu, diagram context menu, and ShortcutManager (customizable via Toolbar settings).
- Bind default shortcuts Ctrl+Alt+C (copy text format) and Ctrl+Alt+V (apply text format).
- Provide full undo/redo support via ApplyElementTextFormatCommand.
- Add SVG icons format-copy and format-apply.
- Include English source strings and German/French translations.
The reader of project.sqlite knew two formats at once: every query asked
the database which column names to use (v2() ? "folio_id" : "folio_uuid"
and so on), and each new format would have added another branch to every
query. Asked in discussion #1440.
An older database is now brought up a format at a time when a .qetz opens
(readyToRead()): format 2 to 3 renames its tables' columns, adds the show
columns and puts the symbols' and wires' uuids and the symbols' type back
in the folio files; 3 to 4 has nothing to change for reading. The reader
then knows only the current format. The next format adds one step.
Checked: the format 2 test file (tests/qttest/fixtures/qetz_format2.qetz)
resaved as .qet and as .qetz gives the same files as master. format2Read
now also checks that every symbol and wire gets its uuid and type back:
it failed with the type left out of the step, which the test did not see
before. ctest 106/106.

The first pass refused a pair whenever a saved terminal had two live
candidates in reach. That happens when a whole drawing moves by half the
spacing of its terminals (pins 10 apart moved 5), and when two terminals
share a place. When one offset fits every unmatched terminal, as when a
whole drawing moved, that offset now settles all pairs; terminals sharing
a place pair in order.

A project saves, for every placed symbol, where each terminal docked, its
orientation and its number. When the symbol's definition is replaced by one
whose terminal sits a few units elsewhere, wires were matched by exact
position and so were dropped on the next open: legacy wires by Terminal::
fromXml(), uuid wires by the uuid derived from the terminal's new place.
Element::fromXml() now pairs each saved terminal that nothing matched
exactly with the live terminal of the same orientation whose docking point
is within 5 units in x and y, only when each is the other's only candidate.
A pair registers the saved number, and the uuid derived from the old place,
which Diagram::findTerminals() checks after the derived uuid of the current
place. Wire ends reattached this way are counted and logged once per folio.
tst_movedterminals covers a move of 3 and 5 units (number and derived
uuid), 6 units, two candidates, and an unmoved terminal.

#1346 rebuilt the Edit menu from a list of named actions, written before
#1354 added Horizontal mirror and Vertical mirror. The two actions ended up
in no menu and on no toolbar, so their shortcuts (M, F) never fired; only
the right-click menu reached them. Add both to the Edit menu after
"Choose texts orientation".
Also correct two labels left behind by later changes:
- Settings > General: the fine-movement step is now used with Ctrl, not
Alt (#1395).
- Terminal editor tooltip: the checkbox is now called "Function
separation" (#1456).

f06fd1130 turned them off because tst_qetcontainer failed there (#1482);
the previous commit fixes that test.

specMatchesSchema() finds the schema in QETZ-FORMAT.md by looking for
"```sql\n". A Windows checkout gives the file CRLF line endings, so the
marker is never found and the test fails with "no schema in
QETZ-FORMAT.md". Drop the carriage returns after reading the file.
Checked by converting QETZ-FORMAT.md to CRLF: the test failed with the
CI message before this change and passes after it; with LF it passes
both ways. All 51 cases of tst_qetcontainer pass.

- register_filetypes.bat (portable Windows build, two copies): .qetz
opens with QElectroTech like .qet.
- AppStream metadata: lists the four file types QElectroTech opens.
- macOS Info.plist: declares the .qet and .qetz types (UTIs), which
recent macOS needs to associate an extension with the application.

Every other QElectroTech file type is application/x-qet-*; the zipped
project was application/x-qelectrotech-project+zip. No release has
shipped it yet, so it is renamed now.
Files written with the old name still open: the reader accepts both, and
the shared-mime-info file keeps the old name as an alias and matches
either on content.

A terminal strip saved with a terminal whose symbol is gone left that
terminal out without a word. It still does, and says so in the log.
The same happens with every folio built: the database is filled from
the document, so a symbol in the file is never missing from it.

Saving a project opened from a .qet writes a .qetz beside it. In a
read-only folder that write fails, but the project had already been
switched to the .qetz path: the window then named a file that does not
exist, and the error said only "Permission denied".
The project now stays the .qet it was when the write fails, and the error
names the file: "Cannot save /path/name.qetz: Permission denied". Save as
still saves it elsewhere.
Found answering the review of #1472 (scorpio810, point 12).

Review of #1472 (scorpio810, points 4-7):
- The .qet made from each .qetz lived in its own temporary folder that was
never removed. Only the newest 8 are kept now, an older version of the
same file is dropped when a newer one is read, and all of them are
removed when the server exits.
- A --resave that failed or timed out could leave a partial .qet behind,
which was kept and read. Only a run that succeeded is used now.
- qet_scan read every .qetz in the folder, each through QElectroTech with
up to 900 s. It reads the first max_qetz (default 20) and lists the rest
as skipped.
- test_edit_writes_a_qetz checks the rotated symbol is the one reported.

The print window exported every page in one orientation, landscape
unless changed, so a portrait folio was shrunk onto a landscape page.
With "Fit in page" on, a PDF export now turns each page to portrait or
landscape as its folio is drawn. The preview keeps one orientation
(QPrintPreviewWidget lays out every page at one paper size), and a
printer keeps it too (only Qt's PDF engine accepts a new page layout
once printing has started). The orientation chosen in the window is
put back afterwards, so it is still the one saved.
The cross-reference links took their target from painter->viewport(),
which QPainter sets once when it opens, so on a turned page they missed
their text. They now use the device's size, as render() does.
tst_printpdforientation exports through the window: an A3 landscape and
an A3 portrait folio get one page each way; tiled pages keep the chosen
orientation; and the links on examples/industrial.qet's turned pages
land where they do when the export starts portrait.

The .qetz files take this branch's side: it already holds #1473, and
adds the folio parts to join().
qetscriptapi.cpp: #1456 gave setConductorProperty() the voltage that
crosses a function separated terminal element; here that function hands
its work to applyConductorProperties(), so the change goes there, with
the properties captured before the pushes. The database path for folios
not built already gives up at such a terminal, so it builds the folio and
takes the same route.

An SVG keeps every picture at full resolution, whatever size it is
drawn at: a folio with 22 phone photos shown at a tenth of their size
gave a 270 MB SVG and took 65 s to write, most of it compressing the
photos again.
The export dialog gets "SVG: smaller pictures" (off by default, kept
with the other export settings), and --export-svg gets
--svg-small-pictures. With it, a picture is stored at four times the
size it is drawn at when that is smaller than the picture; smaller
pictures stay whole. Four times is about 375 dpi on a printed folio.
The exporter sets Diagram::smallPictures() for its own drawing only,
so screen, print, PDF and PNG are unchanged. It is not part of
applyProperties(), which every format uses.
On that project: --export-svg 84.9 s -> 34.5 s (opening is 20 s of
both), 270 MB -> 57 MB, peak memory 2.45 -> 1.86 GB. Rendered at twice
the folio size, the two SVGs differ by more than 32/255 on 0.23 % of
pixels, along photo detail.
tst_svgsmallpictures: an 800x600 picture drawn at 0.1 is stored at
320x240 with the option, through --export-svg and through the
dialog's QPicture route, and at 800x600 without it; a 40x30 picture
stays whole. It fails when the factor is changed.

Each picture of a folio was decoded in turn while its item was built,
a quarter of a second for a 12 megapixel photo. Diagram::fromXml() now
reads every picture of the folio first, decodes them all at once on a
pool of its own (one thread per core, at most one per picture), then
builds the items in file order in the GUI thread as before.
The decoding (base64 text, then the picture file) moves out of
DiagramImageItem::fromXml() into decodePicture(), which touches only
its argument. QImage::fromData() then QPixmap::fromImage() is what
QPixmap::loadFromData() does, so the pixels are the same.
On a 263 MB project with 22 photos on one folio: --info 21.3 s ->
12.5 s, the folio's content 10.6 s -> 3.2 s, opening its .qetz 15.6 s
-> 9.3 s. Peak memory +220 MB (1.81 -> 2.03 GB), the pictures' text
being converted by several threads at once. A resave is byte-identical
to master's, and so is a PNG export.
tst_folioimageload: six pictures come back with their own pixels and
positions, and an <image> without a picture does not stop the others.
It fails when the decoded pictures are handed to the wrong items.

QETZ-FORMAT.md now describes format 4: the computed text left out of the
folio files, QElectroTech's own database built on opening rather than
stored, the tables written without keys, and format 3 among those read.
Tables written without keys keep their declared column types (INTEGER
was written as INT); tst_qetcontainer checks the columns and types
against the document, and that the file has no keys.

QETProject::derivedUuid() copied the whole file content to drop '\r',
then copied it again to prepend the name prefix, before hashing.
On a 263 MB project with embedded photos that took 2 s of a 21 s open.
Hash the content in place, skipping '\r', and set the version 5 bits
as QUuid::createUuidV5() does.
The uuid is unchanged: same result as before on the 23 example
projects, their CRLF copies, edge cases (empty, only '\r') and the
263 MB project, and a resave of that project is byte-identical.
QETZ-FORMAT.md describes format 3: the archive and its files, the
manifest and the version rules, every table and column of project.sqlite
and what it comes from, how rows are keyed, the markers a moved block
leaves, and what reading checks. Asked for in #1440: the format had no
written specification.
tst_qetcontainer checks that the schema the document gives is the one
written: the same tables and columns, in the same order, with the same
types and keys.
