| * buffer.c: evaporate overlays in all indirect buffersStefan Monnier2022-11-051-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes bug#58928. The patch works by moving the `evaporate_overlays` check closer to `itree_delete_gap`. * src/buffer.c (adjust_overlays_for_delete_in_buffer): New function, integrating the functionality of `evaporate_overlays`. (adjust_overlays_for_delete): Use it. (evaporate_overlays): Delete function. * src/buffer.h (evaporate_overlays): Delete declaration. * src/insdel.c (adjust_markers_for_replace): Minor optimization. (adjust_after_replace, replace_range, replace_range_2, del_range_2): Don't call `evaporate_overlays`. * test/src/buffer-tests.el (buffer-tests--overlays-indirect-evaporate): Remove the `:expected-result :failed` attribute.
| * Fix a narrow-to-region vs. overlays-at bugMatt Armstrong2022-10-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | See bug#58703. * src/buffer.c (overlays_in): Add a new TRAILING arg expressing the behavior wanted by `overlays-at', namely to include all overlays beginning at the POS passed to `overlays-at', even if POS is the end of the narrowed region. Pass true and the search range is extended to ZV+1 if END is greater than ZV, just as is done for EMPTY. (overlays_at): Pass 'true' for the new trailing arg. At present this is the only caller passing 'true'. (mouse_face_overlay_overlaps): Pass 'false' for the new trailing arg. (disable_line_numbers_overlay_at_eob): ditto. (Foverlays_in): ditto. * src/editfns.c (overlays_around): ditto. * test/src/buffer-tests.el (sorted-overlays): Add a spot test for this.
| * Rename all exported itree.h functions with the itree_ prefixMatt Armstrong2022-10-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | For the most part, I replaced the interval_tree_ prefix with itree_, interval_node_ with itree_node_, etc. * src/alloc.c: Rename everywhere as appropriate. * src/alloc.c: ditto. * src/buffer.c: ditto. * src/buffer.h: ditto. * src/itree.c: ditto. * src/itree.h: ditto.
| * Prefix all itree.h type names with itree_Matt Armstrong2022-10-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename interval_node -> itree_node, interval_tree -> itree_tree, interval_tree_order -> itree_order. * src/alloc.c: Renames. * src/buffer.c: ditto. * src/itree.c: ditto. * src/itree.h: ditto. * src/lisp.h: ditto. * src/pdumper.h: ditto. * src/textprop.h: ditto. * src/xdisp.h: ditto.
| * Remove the ITREE_NULL macro and use NULL everywhere.Matt Armstrong2022-10-191-1/+1
| | | | | | | | | | | | * src/itree.h: Delete the ITREE_NULL macro. * src/itree.c (check_subtree): Use NULL everywhere. * src/pdumper.c (dump_buffer): ditto.
| * src/textprop.c (get_char_property_and_overlay): Fix bug#58479Stefan Monnier2022-10-141-1/+1
| | | | | | | | | | | | | | | | | | Correct `get-char-property` which failed to ignore empty overlays. * src/textprop.c (get_char_property_and_overlay): Make sure the overlay covers the character. * test/src/buffer-tests.el (buffer-tests--overlay-bug58479): New test. * src/buffer.h (buffer_has_overlays): Avoid `interval_tree_size`.
| * Tighten up handling of `otick`Stefan Monnier2022-10-091-34/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move args between `build_overlay` and `add_buffer_overlay`, to try and keep buffer positions together with their buffer. Be more strict in the `otick` values passed to `interval_tree_insert`. Move a few things around to try and reduce dependencies through `.h` files. Fix a thinko bug in `check_tree`. * src/alloc.c (build_overlay): Remove `begin` and `end` args. * src/buffer.c (add_buffer_overlay): Move from `buffer.h`. Add `begin` and `end` args. (copy_overlays): Adjust accordingly. (Fmake_overlay): Use BUF_BEG and BUF_Z; adjust call to `build_overlay` and `add_buffer_overlay`. (Fmove_overlay): Use BUF_BEG and BUF_Z; Use the new `begin` and `end` args of `add_buffer_overlay` so we don't need to use `interval_node_set_region` when moving to a new buffer. (remove_buffer_overlay, set_overlay_region): Move from `buffer.h`. * src/buffer.h (set_overlay_region, add_buffer_overlay) (remove_buffer_overlay): Move to `buffer.c`. (build_overlay): Move from `lisp.h`. (maybe_alloc_buffer_overlays): Delete function (inline into its only caller). * src/itree.c (interval_tree_insert): Move declaration `from buffer.h`. (check_tree): Fix initial offset in call to `recurse_check_tree`. Remove redundant check of the `limit` value. (interval_node_init): Remove `begin` and `end` args. (interval_tree_insert): Mark it as static. Assert that the new node's `otick` should already be uptodate and its new parent as well. (itree_insert_node): New function. (interval_tree_insert_gap): Assert the otick of the removed+added nodes were uptodate and mark them as uptodate again after adjusting their positions. (interval_tree_inherit_offset): Check that the parent is at least as uptodate as the child. * src/lisp.h (build_overlay): Move to `buffer.h`. * src/itree.h (interval_node_init): Adjust accordingly. (interval_tree_insert): Remove declaration. (itree_insert_node): New declaration.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/buffer.c (delete_all_overlays): Add comment. * src/itree.c (struct interval_generator): New fields `running`, `file`, and `line` moved from `interval_tree`. (interval_stack_push_flagged): Adjust comment to resolve a FIXME. (interval_tree_clear): Replace assignment with an a (interval_tree_iter_next): Delete function. (interval_tree_clear): Don't set `iter_running` here any more. (interval_generator_create): Set it here instead. (interval_tree_iter_start): Fetch `iter` once and for all.

| | | | | | | | | | | | | | | | | | | | | | | | | | When starting an iteration, store __FILE__ and __LINE__ where this happens in the interval_tree structure. * src/buffer.h (buffer_overlay_iter_start): New macro adding __FILE and __LINE__.
