* vim-patch:9.2.1026: heap-use-after-free via DiffUpdated autocommand (#42238)Jan Edmund Lazo2026-10-05
| | | | | | | | | | | | Problem: A DiffUpdated autococmd wiping the current buffer can cause a use-after-free (Evaopo). Solution: Disallow changing the window layout while DiffUpdated autocommand runs. closes: vim/vim#21177 https://github.com/vim/vim/commit/d81720e01a7ce79afa2c55aff5270d9f394ccbbe Co-authored-by: Christian Brabandt <cb@256bit.org>

* vim-patch:9.1.0107: CI: Fix MacOS-14 testsJan Edmund Lazo2026-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: CI: Fix MacOS-14 tests (after 9.1.0070) Solution: Re-enable sound tests by granting Mic access, disable Test_diff_screen because of buggy MacOS diff (non GNU version), re-enable Test_term_gettitle() (Yee Cheng Chin) macos-14 runner was turned on in vim/vim#13943, but it had to turn off a few tests in order for CI to run. Re-enable them and fix the underlying issues. * `Test_diff_screen`: The test failure is due to a bug in Apple's diff utility. Apple introduced a new diff tool based on FreeBSD in macOS 13 and it has buggy behaviors when using unified diff (`-U0`) and the diff is on the first line of the file. Simply disable this test for now if we detect Apple diff (instead of the old GNU diff). Can re-enable this in the future if Apple fixes the issue. * `Test_play_event` / `Test_play_silent`: GitHub Actions currently has an issue with playing sound in CI in macos-14 runners. It for some reason triggers a microphone permission dialog popup which blocks the CI action (see https://github.com/actions/runner-images/issues/9330). To fix this, add a temporary step in macos-14 to manually allow microphone permissions in the runner. * `Test_term_gettitle`: I could not reproduce the failure, so I just turned it on and it seems to run just fine. Maybe it's a timing issue and whatnot but either way that should be fixed when we can reproduce the issue. closes: vim/vim#14032 https://github.com/vim/vim/commit/49f2ba6d41d3c6142deaa4a50b0b16e03969a904 Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>

* vim-patch:9.2.1151: reading before the linemap array with inline:word diffzeertzjq2026-09-30
| | | | | | | | | | | | | | Problem: diff_refine_inline_word_highlight() checks the index of the line after the block, but uses the index of the last line of the block. A block with zero lines makes the index negative and causes heap-buffer underflow (Yuyao Jiang).

* vim-patch:9.2.1099: diff mode redraws slowly with many changes (#41906)zeertzjq2026-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Redrawing or folding a diff with many changes is slow because for every screen line the list of diff blocks is scanned from the start. Solution: Remember the last examined diff block and resume the scan from there while the line number does not move backwards (Julien Voisin). This change is similar to v9.2.1042 (5feaa6c6c201d4d05b833a7230d07da44bf2504b) and v9.2.1036 (f1b454912996d6417acd0d738de0eb7b60902c56) quadratic behaviour replaced with a linear one by keeping track of previous ordered insertions. diff_check_with_linestatus() and diff_infold() are called for every line during redraw and fold updates, with a line number that usually increases monotonically, yet each restarted its scan at tp_first_diff. A cursor into the block list is now kept and cleared whenever a block is freed, allocated or has its line numbers shifted, so the next call continues where the previous one stopped. Scanning the diff blocks during a scroll of a 20000-line diff drops from 4.12G to 1.27G instructions with ~3300 changes, and scales with the number of changes. Tests were added as the change is non-trivial. closes: vim/vim#21256 https://github.com/vim/vim/commit/2ec2a612c7ac9315a17d70f6a2a5ea89ddaea854 Co-authored-by: Julien Voisin <julien.voisin@dustri.org>

* vim-patch:9.1.2085: Use-after-free in winframe_remove()zeertzjq2026-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Use-after-free in winframe_remove() (henices) Solution: Set window_layout_locked() inside winframe_remove() and check that writing diff files is disallowed when the window layout is locked. It can happen with a custom diff expression when removing a window: 1. Buffer was removed, so win_frame_remove() is called to remove the window. 2. win_frame_remove() → frame_new_height() → scroll_to_fraction() → diff_check_fill() (checks for filler lines) 3. diff_check_fill() ends up causing a diff_try_update, and because we are not using internal diff, it has to first write the file to a buffer using buf_write() 4. buf_write() is called for a buffer that is not contained within a window, so it first calls aucmd_prepbuf() to create a new temporary window before writing the buffer and then later calls aucmd_restbuf(), which restores the previous window layout, calling winframe_remove() again, which will free the window/frame structure, eventually freeing stuff that will still be accessed at step 2. closes: vim/vim#19064 https://github.com/vim/vim/commit/ead1dda74a485ef0470e7252d07c1a36b8cde517 Nvim doesn't have this bug as Nvim uses a floating window as autocommand window, and removing it doesn't need winframe_remove().

| | | | | | | | | | | | | | | | | | | | | | | Problem: defaults: 'diffopt' option value can be improved Solution: Update diffopt defaults to include "indent-heuristic" and "inline:char" (Yee Cheng Chin) The default diff options have not been updated much despite new functionality having been added to Vim. - indent-heurstic: This has been enabled by default in Git since 33de716387 in 2017. Given that Vim uses xdiff from Git, it makes sense to track the default configuration from Git. - inline:char: This turns on character-wise inline highlighting which is generally much better than the default inline:simple.

* vim-patch:9.1.1600: using diff anchors with hidden buffers fails silently ↵zeertzjq2025-08-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | (#35218) Problem: diff: using diff anchors with hidden buffers fails silently Solution: Give specific error message for diff anchors when using hidden buffers (Yee Cheng Chin). Diff anchors currently will fail to parse if a buffer used for diff'ing is hidden. Previously it would just fail as the code assumes it would not happen normally, but this is actually possible to do if `closeoff` and `hideoff` are not set in diffopt. Git's default diff tool "vimdiff3" also takes advantage of this. This fix this properly would require the `{address}` parser to be smarter about whether a particular address relies on window position or not (e.g. the `'.` address requires an active window, but `'a` or `1234` do not). Since hidden diff buffers seem relatively niche, just provide a better error message / documentation for now. This could be improved later if there's a demand for it. related: vim/vim#17615 closes: vim/vim#17904 https://github.com/vim/vim/commit/cad3b2421de7b703e0ee619850a8a3bc55454281 Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>
* vim-patch:9.1.1567: crash when using inline diff mode (#35005)zeertzjq2025-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: Crash when using inline diff mode (Ilya Grigoriev) Solution: Set tp_diffbuf to NULL when skipping a diff block (Yee Cheng Chin). Fix an array out of bounds crash when using diffopt+=inline:char when 4 or more buffers are being diff'ed. This happens when one of the blocks is empty. The inline highlight logic skips using that buffer's block, but when another buffer is used later and calls diff_read() to merge the diff blocks together, it could erroneously consider the empty block's diff info which has not been initialized, leaving to diff numbers that are invalid. Later on the diff num is used without bounds checking which leads to the crash. Fix this by making sure to unset tp_diffbuf to NULL when we skip a block, so diff_read() will not consider this buffer to be used within inline diff. Also, add more bounds checking just to be safe. closes: vim/vim#17805 https://github.com/vim/vim/commit/c8b99e2d139cf72c567892e44939f2719f703fa8 Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>
* vim-patch:9.1.1557: not possible to anchor specific lines in diff mode (#34967)zeertzjq2025-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: not possible to anchor specific lines in diff mode Solution: Add support for the anchoring lines in diff mode using the 'diffanchor' option (Yee Cheng Chin). Adds support for anchoring specific lines to each other while viewing a diff. While lines are anchored, they are guaranteed to be aligned to each other in a diff view, allowing the user to control and inform the diff algorithm what the desired alignment is. Internally, this is done by splitting up the buffer at each anchor and run the diff algorithm on each split section separately, and then merge the results back for a logically consistent diff result. To do this, add a new "diffanchors" option that takes a list of `{address}`, and a new "diffopt" option value "anchor". Each address specified will be an anchor, and the user can choose to use any type of address, including marks, line numbers, or pattern search. Anchors are sorted by line number in each file, and it's possible to have multiple anchors on the same line (this is useful when doing multi-buffer diff). Update documentation to provide examples. This is similar to Git diff's `--anchored` flag. Other diff tools like Meld/Araxis Merge also have similar features (called "synchronization points" or "synchronization links"). We are not using Git/Xdiff's `--anchored` implementation here because it has a very limited API (it requires usage of the Patience algorithm, and can only anchor unique lines that are the same across both files). Because the user could anchor anywhere, diff anchors could result in adjacent diff blocks (one block is directly touching another without a gap), if there is a change right above the anchor point. We don't want to merge these diff blocks because we want to line up the change at the anchor. Adjacent diff blocks were first allowed when linematch was added, but the existing code had a lot of branched paths where line-matched diff blocks were handled differently. As a part of this change, refactor them to have a more unified code path that is generalized enough to handle adjacent diff blocks correctly and without needing to carve in exceptions all over the place. closes: vim/vim#17615 https://github.com/vim/vim/commit/0d9160e11ce4b921adff1e5621dd989ce96fb0f3 Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>
* vim-patch:9.1.1473: inconsistent range arg for :diffget/diffput (#34588)zeertzjq2025-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: inconsistent range arg for :diffget/diffput Solution: fix the range specification, place the cursor for :diffput and :diffget consistently on the last line (Yee Cheng Chin) Previously, `:<range>diffget` only allowed using 1 or above in the range value, making it impossible to use the command for a diff block at the beginning of the file. Fix the range specification so the user can now use 0 to specify the space before the first line. This allows `:0,$+1diffget` to work to retrieve all the changes from the other file instead of missing the first diff block. Also do this for `:diffput`. Also, make `:diffput` work more similar to `:diffget`. Make it so that if the cursor is on the last line and a new line is inserted in the other file, doing `:diffput` will select that diff block below the line, just like `:diffget` would. Also clean up the logic a little bit for edge cases and for handling line matched diff blocks better. closes: vim/vim#17579 https://github.com/vim/vim/commit/d75ab0cbf5cfaefab3edb0aa553954de70b236f8 Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>

* vim-patch:9.1.1439: Last diff folds not merged (#34380)zeertzjq2025-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Last diff folds not merged (after v8.1.1922) Solution: loop over all windows in the current tabpage and update all folds (Gary Johnson) This commit fixes a bug where the last two folds of a diff are not merged when the last difference between the two diff'd buffers is resolved. Normally, when two buffers are diff'd, folding is used to show only the text that differs and to hide the text that is the same between the two buffers. When a difference is resolved by making a block of text the same in both buffers, the folds are updated to merge that block with the folds above and below it into one closed fold. That updating of the folds did not occur when the block of text was the last diff block in the buffers. The bug was introduced by this patch on August 24, 2019: patch 8.1.1922: in diff mode global operations can be very slow Problem: In diff mode global operations can be very slow. Solution: Do not call diff_redraw() many times, call it once when redrawing. And also don't update folds multiple times. Unfortunately, folds were then not updated often enough. The problem was fixed by adding a short loop to the ex_diffgetput() function in diff.c to update all the folds in the current tab when the last difference is removed. A test for this was added to test_diffmode.vim. Two of the reference screen dumps for another test in that file, Test_diffget_diffput_linematch(), had to be changed to have all the folds closed rather than to have the last diff block remain open. closes: vim/vim#17457 https://github.com/vim/vim/commit/3fa0d3514b928e0b21ef24594785f9104a3ffafd Co-authored-by: Gary Johnson <garyjohn@spocom.com>
* vim-patch:9.1.1276: inline word diff treats multibyte chars as word char ↵zeertzjq2025-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#33323) Problem: inline word diff treats multibyte chars as word char (after 9.1.1243) Solution: treat all non-alphanumeric characters as non-word characters (Yee Cheng Chin) Previously inline word diff simply used Vim's definition of keyword to determine what is a word, which leads to multi-byte character classes such as emojis and CJK (Chinese/Japanese/Korean) characters all classifying as word characters, leading to entire sentences being grouped as a single word which does not provide meaningful information in a diff highlight. Fix this by treating all non-alphanumeric characters (with class number above 2) as non-word characters, as there is usually no benefit in using word diff on them. These include CJK characters, emojis, and also subscript/superscript numbers. Meanwhile, multi-byte characters like Cyrillic and Greek letters will still continue to considered as words. Note that this is slightly inconsistent with how words are defined elsewhere, as Vim usually considers any character with class >=2 to be a "word". related: vim/vim#16881 (diff inline highlight) closes: vim/vim#17050 https://github.com/vim/vim/commit/9aa120f7ada592ed03b37f4de8ee413c5385f123 Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>

* vim-patch:9.1.1243: diff mode is lacking for changes within lineszeertzjq2025-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Diff mode's inline highlighting is lackluster. It only performs a line-by-line comparison, and calculates a single shortest range within a line that could encompass all the changes. In lines with multiple changes, or those that span multiple lines, this approach tends to end up highlighting much more than necessary. Solution: Implement new inline highlighting modes by doing per-character or per-word diff within the diff block, and highlight only the relevant parts, add "inline:simple" to the defaults (which is the old behaviour) This change introduces a new diffopt option "inline:<type>". Setting to "none" will disable all inline highlighting, "simple" (the default) will use the old behavior, "char" / "word" will perform a character/word-wise diff of the texts within each diff block and only highlight the differences. The new char/word inline diff only use the internal xdiff, and will respect diff options such as algorithm choice, icase, and misc iwhite options. indent-heuristics is always on to perform better sliding. For character highlight, a post-process of the diff results is first applied before we show the highlight. This is because a naive diff will create a result with a lot of small diff chunks and gaps, due to the repetitive nature of individual characters. The post-process is a heuristic-based refinement that attempts to merge adjacent diff blocks if they are separated by a short gap (1-3 characters), and can be further tuned in the future for better results. This process results in more characters than necessary being highlighted but overall less visual noise. For word highlight, always use first buffer's iskeyword definition. Otherwise if each buffer has different iskeyword settings we would not be able to group words properly. The char/word diffing is always per-diff block, not per line, meaning that changes that span multiple lines will show up correctly. Added/removed newlines are not shown by default, but if the user has 'list' set (with "eol" listchar defined), the eol character will be be highlighted correctly for the specific newline characters. Also, add a new "DiffTextAdd" highlight group linked to "DiffText" by default. It allows color schemes to use different colors for texts that have been added within a line versus modified. This doesn't interact with linematch perfectly currently. The linematch feature splits up diff blocks into multiple smaller blocks for better visual matching, which makes inline highlight less useful especially for multi-line change (e.g. a line is broken into two lines). This could be addressed in the future. As a side change, this also removes the bounds checking introduced to diff_read() as they were added to mask existing logic bugs that were properly fixed in vim/vim#16768. closes: vim/vim#16881 https://github.com/vim/vim/commit/9943d4790e42721a6777da9e12637aa595ba4965 Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>
* vim-patch:9.1.1165: diff: regression with multi-file diff blocks (#32702)zeertzjq2025-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Vim's diff block merging algorithm when doing a multi-file diff is buggy when two different diff hunks overlap a single existing diff block (after v9.1.0743) Solution: fix a couple bugs in this logic: 1. Fix regression from v9.1.0743 where it's not correctly expanding the 2nd overlap correctly, where it always expands without taking into account that this was always taken care of when the first overlap happened. Instead, we should only grow the 2nd overlap if it overhangs outside the existing diff block, and if we encounter a new overlapping diff block (due to overlap chaining). 2. When we expand a diff block to match the hunk size on the orig side (when handling the first overlap), we expand the same amount of lines in the new side. This is not sound if there exists a second overlap hunk that we haven't processed yet, and that hunk has different number of lines in orig/new. Fix this by doing the corresponding counter adjustment when handling 2nd/3rd/etc overlap by calculating the difference in lines between orig and new side.
