QETProject::writeBackup() was Qt5-only: the Qt6 branch of the guard was
an empty placeholder, so on Qt6 no backup was ever written - a silent
data-loss risk (a crash loses everything since the last manual save),
found by ispyisail in qelectrotech#553.
The Qt5-style QtConcurrent::run(function, reference-args) call did not
survive the Qt6 API change; a lambda capturing the (implicitly shared)
document copy behaves identically on both, so the version guard goes
away entirely.
Verified at runtime on the Qt6/Windows build: opening a project creates
the autosave triple (.qetautosave + .lock + .path) with valid XML
content, and a clean exit removes it again. The CLI keeps backups
disabled via setBackupEnabled(false), unchanged.
(cherry picked from commit 0f65ae8c4b2782fbfe97111bc8b369cc105ec592)
Requested in #553 to compare Qt5 and Qt6 builds. QET already reports how
long the elements collection takes to load (ElementsCollectionWidget::
reload); this adds the equivalent for opening a project.
The phases are reported separately rather than as a single total. Reading
the XML and building the objects is mostly independent of the Qt version,
whereas refreshing the diagrams is graphics-scene work -- a single number
would mix the two and could suggest a Qt version makes no difference when
the part that changed is simply not where the time goes. Measured on the
example projects, XML parsing is 3-7% of the total and diagram
construction 77-83%, so the distinction matters in practice.
QETProject::openFile() reports the total with the parse/build split, and
readProjectXml() reports the build phases:
Project content built in 1.391 seconds (elements collection 0.009,
diagrams 1.153, terminal strips 0, refresh 0.196, database 0.033)
Project "example.qet" (3399 KiB) opened in 1.505 seconds
(xml parsing 0.11, content 1.395)
Logged with qInfo(), matching the existing collection timer, so it lands
in the normal log without a debug build.

qAsConst was deprecated in Qt 6.6; std::as_const (C++17, already the
project standard) is the drop-in replacement. Clears 46 -Wdeprecated-
declarations warnings across 18 files. No behavioural change.
Provide a small KAutoSaveFile-compatible implementation for the no-KF5 build path and use it to keep the existing crash-recovery code active when BUILD_WITH_KF5=OFF.
The normal KF5 build still uses the KDE KAutoSaveFile implementation.

writeBackup() fires QtConcurrent::run(QET::writeToFile, ..., &m_backup_file)
fire-and-forget: the QFuture was discarded and nothing kept m_backup_file
alive until the worker finished. If the QETProject was destroyed first, the
worker wrote through the freed member -> use-after-free crash in
QET::writeToFile (intermittent; ~1/6 on short-lived CLI runs).
Store the QFuture and waitForFinished() in ~QETProject (and before
setFilePath() re-points the managed backup file). Also skip launching a new
backup while one is still running, so two threads never write m_backup_file
at once.
The Qt6 path is still a TODO stub and the QtConcurrent block is KF5-only, so
this affects only the Qt5/KF5 build that actually has the backup code.
Saving a read-only project to a writable location (e.g. Save As to /tmp)
left it marked read-only, so it stayed uneditable until closed and
reopened. Two issues in QETProject::write():
- The guard refused to write whenever QFileInfo(path).isWritable() was
false. For a Save As to a *new* file that test is always false (the file
doesn't exist yet), so it could wrongly block saving a read-only project
elsewhere. Now it checks the directory's writability for a new file.
- After a successful write the read-only flag was never cleared. Since the
file was just written, it is writable, so clear it (setReadOnly(false)
emits readOnlyChanged, re-enabling editing live).
Fixes#217.
QETProject schedules an asynchronous crash-recovery backup on construction
(writeBackup() -> QtConcurrent::run(QET::writeToFile, ..., &m_backup_file)).
In one-shot CLI mode the QETProject is destroyed as soon as the command
returns, while that background write still references its m_backup_file
member — an intermittent use-after-free segfault during teardown (~1 in 6
runs; observed on --resave and --set-titleblock).
A crash-recovery backup is meaningless for a short-lived headless command,
so add QETProject::setBackupEnabled(false), called from the CLI entry in
main(). writeBackup() then early-returns, so no background write is ever
launched. Fixes the crash for all CLI commands. See #492.
Modification of the int BACKUP_INTERVAL from 2 min to 20 min used by
KautoSaveFile.
On a large project with a 256 MB folio printed in A0 format, the
graphical interface freezes for 30 seconds when KautoSaveFile writes
this large amount of data to the disk every two minutes.
Even if the programme crashes, you only lose 20 minutes of your work,
which is not a big deal.
Thanks to Enzo for reporting it and finding the problem.
All export files that are derived from the project (BOM,
nomenclature, etc.) are saved in the same directory by default.
In this context, the standard directories have been grouped
together in qetapp.cpp / qetapp.h so that only one place needs
to be searched for in case of any adjustments.
TerminalStripLayoutPattern class is now a shared pointer between all
terminal strip item.
QETProject have now a new class : ProjectPropertiesHandler
the goal of this class is to manage every kind of properties used in the
project, this class will be strongly used in future.
* terminal_strip:
Terminal strip item can saved / loaded to .qet file
