project.sqlite now holds both what QElectroTech keeps in its project database (the index D2 wrote as index.sqlite) and the document's engineering data, the latter's tables named doc_<name> beside the former's -- element, element_info, link and conductor exist in both (QetContainerDb's SQL names them as before; Database::sql() puts the prefix on). The manifest says format 3, min-reader 3: a format 2 reader would find no tables of its names. Format 2 files, with or without an index.sqlite entry, are read as before: the prefix is found from the file (doc_meta). A .qetz with an index opens from project.sqlite. Measured: the 136-folio f2099 1.8 s, 5.2 MB (the two table sets still overlap: D3b). Checked: tst_qetcontainer with the format 3 names, 34/34; a format 2 file of the last commit opens from its index.sqlite and saves the same; corpus 342: 340 .qetz carry the index in project.sqlite and open from it, saved back = eager = master on all 342. ctest 96/96 with and without QET_LAZY_FOLIOS=1.

/**
|
|
@brief The QetContainerDb namespace
|
|
The engineering data of a project, moved between its document and the
|
|
project.sqlite of a .qetz: what a folio's title block says, a symbol's
|
|
information, a coil's contacts, a wire's ends and number. In a .qetz
|
|
these live only in the database; the folio files keep where things are
|
|
drawn. extract() takes them out of the document into a database,
|
|
restore() puts them back, so that restore(extract(d)) is d.
|
|
|
|
Each moved item leaves its key in the document (qetz-key, qetz-folio):
|
|
its uuid where that is unique, else a made-up one. A block of a shape
|
|
this does not model -- a value holding elements, say -- stays in the
|
|
document, so nothing can be lost by moving.
