New commits: commit b864380d265ac7cc8aec291b0e77f4e61b570c0e Author: Mike Kaganski <[email protected]> AuthorDate: Sun Jan 18 20:41:01 2026 +0500 Commit: Miklos Vajna <[email protected]> CommitDate: Mon Jan 19 09:17:43 2026 +0100 tdf#170381: try to avoid handling of split-but-not-yet-moved floating tables When a floating table is being split, it creates a follow table. Later, still in Split, the follow gets reformatted, creating a follow fly and its anchor (which itself is a follow of a text frame). But at this point, the anchor is still next to its precede, and all of these haven't yet moved to the next page (see SwFrame::GetNextFlyLeaf); the follow fly is still registered in the precede's page. The actual move will happen only when the follow anchor will move to the next page as part of higher-level layout. In this intermediate state, after split but before move, the floating table and its fly should get specal handling. It must not be taken into account when calculating object intersections; it must not try to move forward itself (as part of its own re-layout). On the other hand, it can't be excluded from any handling. It must calculate its size and position (even though its position will eventually be changed) - without that, things fall apart badly. When working on it, it turned out, that SwTextFormatter::FormatLine had a problem when calculating its real height. The old code used to set the height of the last-on-page line to the full available space, plus one; and there was an exception for `HasNonLastSplitFlyDrawObj` case, where "plus one" was not used. But that wasn't enough; in case of a floating table in floating table, using spacing, the calculation created lines that were too high, causing oscillation. I attempted to find a better algorithm to calculate the height, e.g. using Grow with bTxt set to true; but all things I tried failed. Thus I disabled the call to SetRealHeight in case of HasNonLastSplitFlyDrawObj. It feels unsafe, and may require more work, if it turns out problematic. Another problem was found in SwToContentAnchoredObjectPosition::CalcPosition. It has a code that calls SwTabFrame::SetDoesObjsFit( false ), but this may force moving of objects without final size. The condition was improved. In GetFlyAnchorBottom, there is a code that decides if legacy behavior must be used, where the fly can overlap the bottom margin. It checked if anchor is in body. But it didn't consider the case when the anchor itself was in a fly (and in that case, thought that the anchor isn't in body); that made the floating-table-in-floating-table case calculate anchor bottom incorrectly (as in legacy mode), causing move forward and layout loop. Fixed here. One existing test (testSplitFlyInTextSection in sw/qa/core/layout/flycnt.cxx) started to hang with this change. That seems to not be a real regression per se: turns out, that floattable-in-text-section.docx already started to hang in master when opened in GUI; and the change only aligned that between the GUI and the unit test. I couldn't find a fix for that; the test was disabled.
