Mike Kaganski 8a017d25a6 Avoid COW overhead using css::uno::Sequence 
The scenarios are:

1. Calling sequence's begin() and end() in pairs to pass to algorithms
   (both calls use getArray(), which does the COW checks)
2. In addition to #1, calling end() again when checking result of find
   algorithms, and/or begin() to calculate result's distance
3. Using non-const sequences in range-based for loops, which internally
   do #1
4. Assigning sequence to another sequence variable, and then modifying
   one of them

In many cases, the sequences could be made const, or treated as const
for the purposes of the algorithms (using std::as_const, std::cbegin,
and std::cend). Where algorithm modifies the sequence, it was changed
to only call getArray() once. For that, css::uno::toNonConstRange was
introduced, which returns a struct (sublclass of std::pair) with two
iterators [begin, end], that are calculated using one call to begin()
and one call to getLength().

To handle #4, css::uno::Sequence::swap was introduced, that swaps the
internal pointer to uno_Sequence. So when a local Sequence variable
should be assigned to another variable, and the latter will be modified
further, it's now possible to use swap instead, so the two sequences
are kept independent.

The modified places were found by temporarily removing non-const end().

Spreadsheet Application Code

You can dump some information in a dbgutil build:

Shortcuts

CTRL+SHIFT+F12

Dumps the column width of the first 20 columns.

CTRL+SHIFT+F11

Dumps the graphic objects and their position and size in pixel.

CTRL+SHIFT+F6

Dumps the SfxItemSet representing the cell properties' of the current selection as a xml file. The file will be named dump.xml

The Cache Format

ScDocument::StoreTabToCache allows storing the content (not the formatting) of a table to a binary cache format.

The format is column orientated which allows quick serialization of the table.

  • Header:

    • Number of Columns: 64 bit unsigned integer

  • Column:

    • Column Index: 64 bit unsigned integer
    • Column Size: 64 bit unsigned integer
    • For each cell type block a new ColumnBlock

  • ColumnBlock:

    • Start Row: 64 bit unsigned integer
    • Block Size: 64 bit unsigned integer
    • Type: 8 bit unsigned integer
      • 0 : empty
      • 1 : numeric
        • for each cell: 64 bit IEEE 754 double precision value
      • 2 : string
        • for each cell: 32 bit signed string length followed by string length bytes of the string (UTF-8)
      • 3 : formula
        • for each cell: 32 bit signed string length followed by the formula in R1C1 notation as a string

Functions Supporting Wildcards or Regular Expressions

As this comes up every now and then, and rather should be documented in an extra list of the Help system, functions that support Wildcards or Regular Expressions and depend on the setting under Tools -> Options -> Calc -> Calculate are those that in ODF OpenFormula (ODFF) are defined to depend on the HOST-USE-REGULAR-EXPRESSIONS or HOST-USE-WILDCARDS properties, see https://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part2.html
