Making the Informations tab visible for Slave elements is only half the
change: ElementScene::toXml() writes the <elementInformations> block for
Simple, Master, Terminal and Thumbnail, and Slave was not in that list. It
is the only place in the tree that writes that block, so the editor would
have shown an editable tab for a slave, accepted whatever the user typed
into it, and dropped it silently on save.
Visible in the shipped collection, which matches the condition exactly:
0 of 75 slave elements carry an <elementInformations> block, against 41 of
70 terminal elements.
Adding Slave is safe in both directions. ElementData::fromXml() reads
<elementInformations> unconditionally, with no check on the base type, so
existing slave elements are unaffected and newly written ones load back
correctly. It also makes populateTree()'s PLC-slave branch reachable for
the first time -- the five PLC info rows it adds are stored in
m_informations, so until now they could not have been saved either.

exportBomCsv() calls query.value(i).toString(). QSqlQuery::value() returns
a QVariant, but the translation unit only ever sees the forward declaration
that arrives through qobject.h, so the call does not compile:
sources/bomexport.cpp:79:50: error: invalid use of incomplete type
'class QVariant'
79 | values.append(query.value(i).toString());
Reproduced on a clean checkout of master with Qt 5.15.18. Qt6 pulls the
full definition in by another path, so the Windows CI workflow does not
see it.

When a placed nomenclature or summary table cannot display every row its
model holds, checkInsufficientRowsCount() informs the user with a modal
message box. It used QMessageBox directly rather than QET::QetMessageBox,
so it ignored the non-interactive mode that main.cpp sets for the
command-line verbs, and every headless verb (--info, --resave, --export-*)
blocked forever on a dialog nobody could answer.
This is the same defect fixed in e3d11a499 for the other modals reachable
from the command line; this call site was missed.
Found with a gdb backtrace on a hung --info: the process was parked in
QDialog::exec() under this function.

ElementPictureFactory caches the QPicture it builds for an element
definition, keyed by that definition's uuid. Definitions saved before uuids
were written do not have one, and every one of them presented the same null
uuid. getPictures() spotted that and took an uncached path, so the drawing
was rebuilt from the XML for every instance the project placed.
Counted on the shipped examples:
examples/m_000.qet 831 builds for 97 definitions
examples/affuteuse_250h.qet 256 builds for 106 definitions
examples/industrial.qet 65 builds, 553 cache hits (has uuids)
13 of the 23 example projects carry definitions without a uuid, so this is
not a rare shape.
Derive a key from the location when the definition has no uuid of its own.
ElementsLocation::toString() qualifies an embedded path with the id of the
project owning it, and QETApp hands out project ids from an ever-increasing
counter and never reuses them, so the derived key cannot collide with an
element of another project.
Measured with callgrind, which counts instructions and so does not depend
on what else the machine is doing, opening examples/affuteuse_250h.qet:
4,801,381,735 -> 4,285,411,908 instructions (-10.7 %)
ElementPictureFactory::build 995 M -> 478 M
ElementPictureFactory::getPictures 1289 M -> 774 M
The halving of build() matches the counters independently: 106 definitions
against 256 instances is 41 %, and the cost falls to 48 %.
This also retires a latent aliasing bug rather than a measured one:
build() inserted into m_primitives_H under the same null uuid for every
definition lacking one, and getPrimitives() read back through that shared
key. Its only caller is the image export dialog, which the command line
does not reach, so no wrong output could be demonstrated here -- but the
entries could only ever have belonged to whichever element was built last.
--info stays byte identical on all 23 example projects, and the SVG export
of affuteuse_250h.qet -- a project whose definitions all lack uuids -- is
byte identical too.

setPainterStyle() built its QRegularExpression as a local, so the pattern
was compiled from scratch on every call -- and it is called for every
graphics primitive of every element instance a project places. A callgrind
profile of opening examples/affuteuse_250h.qet put 28 % of all instructions
inside libpcre2, and 12 % of the whole run inside this one function.
Making it static const compiles the pattern once for the life of the
process. Nothing else changes: same pattern, same matching, same named
captures.
Measured with callgrind, which counts instructions and so does not depend
on what else the machine is doing, opening examples/affuteuse_250h.qet:
4,801,381,735 -> 4,297,629,948 instructions (-10.5 %)
setPainterStyle 582 M (12.13 %) -> 79 M (1.83 %)
--info stays byte identical on all 23 example projects, and so does every
SVG this produces for industrial.qet -- which is the output that would
change if the styles were parsed any differently.

Destroying a project cost more than loading it: on a 1000 folio project
--info reported its work done in 160 s but the process ran for 657 s, and
the difference was ~QETProject().
Timing each destructor puts 94 % of that teardown in
~QetGraphicsTableItem(), with the cost per table doubling as the project
grows (48 ms at 100 folios, 122 ms at 250). The database's own per-element
deletes are 1 % of it and linear; element and conductor teardown is linear.
A table destructor repairs the chain it belonged to, which relinks the
neighbouring tables, which assigns a model -- and one branch of
setPreviousTable() builds a fresh ProjectDBModel, whose copy constructor
calls setQuery(), which rebuilds the whole database. Destroying a 250 folio
project did that 12 times, for a project that is being thrown away.
So block the rebuild for the lifetime of the destructor, next to the
blockSignals(true) already there for the same reason. Nothing can observe
the result: the database is destroyed moments later as a member of the
project. Teardown drops about fivefold at every size measured -- 1.30 s to
0.26 s at 100 folios, 7.75 s to 1.73 s at 250, 19.92 s to 4.02 s at 400 --
and the number of full rebuilds in a run stops growing with project size.
Teardown is still superlinear, now dominated by
QetGraphicsTableItem::setUpColumnAndRowMinimumSize() measuring every cell of
the nomenclature each time a chain is relinked. That is left alone here.
--info stays byte identical on all 23 example projects, as do --export-bom,
--export-wires, --export-cables, --export-nets and --export-wiring.

ProjectDBModel::setQuery() calls projectDataBase::updateDB(), which drops
and repopulates every table in the database. The rebuild does not depend on
the query, so each table model that queries the database while a project is
being read triggers another complete repopulate of the same content.
Opening a 100 folio project ran updateDB() 26 times, 9.9 s of a 15.7 s load.
Two changes, because the first alone is not enough:
setUpdateBlocked() lets a bulk operation suppress the rebuild and do it
once when it is done. readProjectXml() already wrapped the load in
blockSignals(true) "to avoid hundreds of unnecessary emitted signal", but
that suppresses only the signal, not the work it announces; this extends
the same intent to the work. Both early returns in readProjectXml() sit
before the block, so no path leaves the database permanently blocked.
Further rebuilds are triggered after readProjectXml() returns, where the
load phase timers cannot see them -- with only the block in place
updateDB() still ran 5 times on examples/industrial.qet. So the database
now also tracks whether anything has changed since the last rebuild, and
skips repopulating when nothing has. dataBaseUpdated() is still emitted in
that case: callers and models rely on it to refresh, and what they read
back is the same either way. Every method of the class that writes rows
marks the flag; from outside, the database is reachable only through
newQuery(), and all five call sites read.
Repeating the rebuild was wasteful rather than wrong -- each
populate*Table() begins with a DELETE -- so this changes no output.
Verified byte identical --info on all 23 example projects, and identical
--export-bom, --export-wires, --export-cables, --export-nets and
--export-wiring on industrial.qet. Its load drops from 5.51 s to 5.31 s
(median of 6).

The remaining two defects from bugtracker #671's original analysis,
which #686 knowingly didn't cover (see that PR's review thread and the
comment on the now-closed #672).
## #671 item 5: the XML matching ignored nesting
prefixFromLabelFile() was a flat token scan: it matched any <category
name="..."> whose name equalled the next path segment, with no check
that the match was actually a *child* of the previous match. It gave
correct results on the shipped 10_electric/qet_labels.xml only because
that file's document order happens to line up with its hierarchy --
any file with a same-named category at the wrong nesting depth would
silently return the wrong prefix.
Reproduced with a synthetic file where a top-level sibling category
happens to share a name with what should be an unmatched grandchild:
the old (already re-verified-fixed-for-whitespace) lookup returns a
prefix from a completely unrelated branch of the document; this
rewrite correctly reports "not found".
Fixed by replacing the QXmlStreamReader token walk with a QDomDocument
walk that only ever considers a matched node's direct <category>
children (firstChildElement()/nextSiblingElement(), scoped to that
node), which cannot cross into a same-named sibling subtree. This also
makes the whitespace-dependence fixed in #686 moot for the same
reason: DOM parsing doesn't distinguish pretty-printed from minified
input to begin with.
The inheritance rule ("if a directory has no prefix, use its parent's,
and so on") and the empty-<prefix/>-overrides-inheritance behaviour
#686 added both carry over unchanged: a category's own <prefix> child,
even an empty one, always overrides whatever a shallower ancestor
already provided; a category with no <prefix> child at all leaves the
inherited value untouched.
## #671 item 2: common-collection trees other than 10_electric
The lookup only ever consulted commonElementsDir()/10_electric --
literally: `if (current_location.fileName() == "10_electric")`. The
common collection ships four other top-level trees (20_logic,
30_hydraulic, 50_pneumatic, 60_energy); none of them could carry a
qet_labels.xml at all, because nothing ever looked for one.
Generalised to commonElementsDir()/<tree>/qet_labels.xml for whichever
top-level tree the element's path actually walks up to, tried first,
then custom, then company -- each of the latter two tried against both
a from-root layout (matching a custom/company file organised as a
mirror of the common collection, tree name included) and a
tree-relative one (matching a file scoped to just one tree), so
existing custom files keep working either way. This is the same
multi-candidate structure #686 already established for custom-then-
company; it now also covers which common-collection tree to check.
## Testing
Same constraint as #686: no working full build in this sandbox
(missing generated headers/deps), so the exact functions as committed
were extracted into a standalone Qt6 harness and run against the real
shipped 10_electric/qet_labels.xml (pretty-printed and minified),
a synthetic empty-prefix-override file, and the nesting-trap file
above -- 9/9, including the three cases #686 already fixed (direct
prefix, inherited prefix, not-found) staying correct, confirming this
rewrite doesn't regress that work.
Not exercised here (needs a real running QETApp / ElementsLocation,
which the standalone harness can't stand up): the elementPrefixForLocation()
candidate-list wiring itself -- collection_root computation, the
from-root/tree-relative dual lookup, and the common-then-custom-then-
company ordering. That code is mechanical and was reviewed carefully
by hand, but it has not been run.
Requested by @scorpio810 in review: an empty <prefix/> in the custom
collection should cancel a company-collection prefix, not fall through
to it. QXmlStreamReader::readElementText() returns a null QString for an
empty element, and the caller's isNull() check treats that the same as
"not found" -- distinguish the two so an explicit override actually
overrides. Verified in a standalone harness against a synthetic
override file, pretty-printed and minified.
Two more while in the same function, both from the original bugtracker
#671 analysis that this PR only partially addressed:
- QString path[10] with an unbounded index becomes a QStringList. The
deepest category in the shipped collection already needs 9 of the 10
slots; a custom collection can nest deeper, and overflow was writing
QString objects past the end of a stack array (#671 item 3).
- The common-collection lookup still concatenated
commonElementsDir() + "10_electric/qet_labels.xml" directly.
commonElementsDir() returns the configured path verbatim with no
guaranteed trailing separator, so relocating the collection to a path
without one silently mangles this into one word and the file is never
found -- the single most-reported cause of "prefixes don't work"
(#671 item 1, forum #2178/#2651). QDir::filePath() joins correctly
either way; applied to all three lookups (common, custom, company).
Also fixes a defect not in that original analysis: the token-matching
loop in prefixFromLabelFile() advanced twice per matched element --
once explicitly after a match, once more unconditionally at the bottom
of the loop -- which only produced the right result because a
pretty-printed file inserts a whitespace Characters token between
adjacent elements for the second advance to land on. A minified
qet_labels.xml has no such token, so the second advance skips clean
over the very element being searched for and the lookup silently finds
nothing -- reproduced against the real shipped 10_electric/qet_labels.xml
(returns "" instead of "K" for a plain coil, on every case tested, not
just the inheritance one). A single `continue` after a handled match
removes the double advance.
Testing: extracted the exact functions as committed into a standalone
Qt6 harness (outside the full QET build, which needs a dependency
fetch this sandbox doesn't have) and ran them against the real shipped
qet_labels.xml, pretty-printed and minified, covering a direct prefix,
inherited-from-ancestor prefix, not-found, and the explicit-empty-
override case -- 8/8, matching between formats, no regressions in the
pretty-printed results. The QDir::filePath() fix was verified
separately against both a trailing-slash and no-trailing-slash base
path. Not yet built inside the actual application (pugixml and other
generated headers aren't available standalone); the algorithm itself,
which is where all four defects lived, is what was under test.
A .qm compiled from a 0%-translated .ts (fi, no, rs, sk, sl, sr) loads
successfully but contains no messages, so setLanguage() treated the
language as loaded and never fell back to qet_en: users got the French
source strings instead of English. Treat an empty translator as not
loaded.
Also log the QET and Qt .qm files actually loaded in the startup
diagnostics (MachineInfo), to make translation reports easier to triage.
windeployqt runs with --no-translations, so standard buttons (OK/Cancel)
and dialogs stayed in English. Copy each qtbase_XX.qm from the MSYS2 Qt
translations into files/lang/qt_XX.qm, where QETApp::setLanguage() looks,
with aliases for QET languages Qt only ships with a region (pt, zh).
Standard buttons (OK/Cancel) and dialogs are translated by qtbase_XX.qm,
which macdeployqt does not deploy. QETApp::setLanguage() falls back to
lang/qt_XX.qm, so copy each qtbase_XX.qm there, with aliases for QET
languages Qt only ships with a region (pt -> pt_PT, zh -> zh_CN).
macdeployqt kept /opt/homebrew paths (e.g. libbrotlicommon's install id).
Rewrite them to @rpath/libX.dylib, copying the library into Frameworks
if needed, over 3 passes to handle chained dependencies.
Recent Homebrew bottles (brotli, webp, sharpyuv) reference their deps as
@rpath/libX.dylib, which macdeployqt skips. Copy them from /opt/homebrew/lib
into Contents/Frameworks after macdeployqt, and abort if any @rpath or
/opt/homebrew reference remains unresolved. Drop the ineffective -libpath.
polluting the source directory during out-of-source builds and it is standard that these files should be located inside the build directory during the build step.
Second of @scorpio810's review notes on #630:
exportWiring() follows the existing CLI exporters (QTextStream, plain
QFile). On Qt6 the output is UTF-8, so encoding is fine. Once #830 is
in, it could optionally reuse BomExport::writeCsv() to get a BOM,
which Excel needs to detect UTF-8 when opening the file directly, and
an atomic write.
Done directly rather than waiting on #830, since neither half depends on
it and both are small.
The bytes were already UTF-8; what was missing is the mark that tells
Excel so. Opening a .csv without one, Excel falls back to the local
8-bit codepage and mangles any accented element label -- the common case
for this project's users.
QSaveFile replaces QFile so a failure part-way through leaves the
previous file intact instead of a truncated one. QSaveFile is already the
codebase's pattern for this (QET::writeToFile, qet.cpp:664).
Verified on perceuse.qet: output now starts ef bb bf, the header follows
intact, all 156 rows are preserved, and the file parses as utf-8-sig.
Pointing the exporter at a missing project leaves an existing target file
untouched, where before it would have been truncated.
Left the other CLI exporters alone. They share the same pattern, but
changing exportBom() would add a BOM to output that existing scripts
already consume, which is a behaviour change outside the scope of this
review note.

Follows @scorpio810's review note on merging #630:
ORDER BY diagram_position, wire_number sorts wire numbers as text,
so "10" comes before "9".
Confirmed against the corpus: perceuse.qet put 111 before 12, and
affuteuse_250h.qet put 45 before 5. industrial.qet happened to look
correct only because its wire numbers are all the same width.
Wire numbers are free text and are not always numeric -- perceuse.qet
also carries an unresolved "%sequ_1" -- so the ordering has to cope with
both. Numeric values come first, ordered by value; anything else follows,
ordered as text. The trailing wire_number keeps ties stable.
Fixed in both places the query appears: the CLI exporter and the wiring
list dialog. They had the same ORDER BY, so fixing only one would have
made the dialog and --export-wiring disagree about the order of the same
data.
Verified on perceuse, affuteuse_250h, industrial and tremie_vibrante:
zero out-of-order numeric pairs afterwards, row counts unchanged, and
"%sequ_1" now sorts after the numbers rather than among them. Folio 3 of
perceuse.qet reads 0 1 2 3 4 4 5 5 6 6 7 7 12 12 where it previously
interleaved 111 before 12.
