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 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.
