Format 3 folio files lose what building a folio computes (QetContainer::dropComputed()): a wire's description of its ends (element1_label, element1_name, element1_linked, terminalname1 and the same for end 2), the content of a symbol text showing the symbol's information or a composition of it, and -- when the project database's index is written, every symbol with a uuid of its own -- a symbol's list of its terminals. What may go was found by test, not by reading: on 342 projects saved by this version, each kind taken out of the file, the project opened and saved: the wire ends came back in all 244 that had them, the symbol texts in all 201, the terminal lists in 305 of 306 -- not in the file whose symbols share a uuid (#1408), where wires find their ends by them; such a project gets no index, so it keeps them. Stays, for now: labels made from a formula and wire numbers made from one, in the database (opening from the index and numbering read them), and a table's size (the user's as much as computed). tst_qetcontainer compares a joined document with the original less what is computed, and computedNotKept checks a file holding both kinds (one filled in by the test) loses them -- it fails when nothing is dropped. Through QElectroTech, 342 projects: a .qetz opened from its index and saved as .qet = eager = master; every folio of industrial and f2099 drawn and linked as eager (f2099 but its 3 render-noise folios). ctest 96/96 with and without QET_LAZY_FOLIOS=1.

@brief The QetContainer namespace
|
|
Splits a project document into the parts of a .qetz file and joins
|
|
them back:
|
|
|
|
mimetype first, stored
|
|
manifest.xml format and oldest format allowed to read it
|
|
project.xml the project, each part replaced by
|
|
<qetz-part file="..."/>
|
|
project.sqlite the engineering data (format 2,
|
|
QetContainerDb): title-block fields, symbol
|
|
information, links, wires
|
|
folios/<uuid>.xml one per folio
|
|
elements/.../<name> the project's symbol definitions
|
|
titleblocks/<name>.titleblock
|
|
images/<sha256>.png folio pictures, once each, not base64
|
|
|
|
join(split(d)) is d. Nothing here knows what the parts mean: the
|
|
project is read and written by the same code as a .qet file.
