patch 9.0.2168: Moving tabpages on :drop may cause an endless loop
Problem: Moving tabpages on :drop may cause an endless loop
Solution: Disallow moving tabpages on :drop when cleaning up the arglist
first
Moving tabpages during drop command may cause an endless loop
When executing a :tab drop command, Vim will close all windows not in
the argument list. This triggers various autocommands. If a user has
created an 'au Tabenter * :tabmove -' autocommand, this can cause Vim to
end up in an endless loop, when trying to iterate over all tabs (which
would trigger the tabmove autocommand, which will change the tpnext
pointer, etc).
So instead of blocking all autocommands before we actually try to edit
the given file, lets simply disallow to move tabpages around. Otherwise,
we may change the expected number of events triggered during a :drop
command, which users may rely on (there is actually a test, that expects
various TabLeave/TabEnter autocommands) and would therefore be a
backwards incompatible change.
Don't make this an error, as this could trigger several times during the
drop command, but silently ignore the :tabmove command in this case (and
it should in fact finally trigger successfully when loading the given
file in a new tab). So let's just be quiet here instead.

closes: #13686

# Contributing to Vim Patches are welcome in whatever form. Discussions about patches happen on the [vim-dev][0] mailing list. If you create a pull request on GitHub it will be forwarded to the vim-dev mailing list. You can also send your patch there directly (but please note, the initial posting is subject to moderation). In that case an attachment with a unified diff format is preferred. Information about the mailing list can be found [on the Vim website][0] A pull request has the advantage that it will trigger the Continuous Integration tests, you will be warned of problems (you can ignore the coverage warning, it's noisy). Please consider adding a test. All new functionality should be tested and bug fixes should be tested for regressions: the test should fail before the fix and pass after the fix. Look through recent patches for examples and find help with ":help testing". The tests are located under "src/testdir". Contributions will be distributed with Vim under the Vim license. Providing a change to be included implies that you agree with this and your contribution does not cause us trouble with trademarks or patents. There is no CLA to sign. # Reporting issues We use GitHub issues, but that is not a requirement. Writing to the Vim mailing list is also fine. Please use the GitHub issues only for actual issues. If you are not 100% sure that your problem is a Vim issue, please first discuss this on the Vim user mailing list. Try reproducing the problem without any of your plugins or settings: vim --clean If you report an issue, please describe exactly how to reproduce it. For example, don't say "insert some text" but say what you did exactly: `ahere is some text<Esc>`. Ideally, the steps you list can be used to write a test to verify the problem is fixed. Feel free to report even the smallest problem, also typos in the documentation. You can find known issues in the todo file: `:help todo`. Or open [the todo file][todo list] on GitHub to see the latest version. # Syntax, indent and other runtime files The latest version of these files can be obtained from the repository. They are usually not updated with numbered patches. If you find a problem with one of these files or have a suggestion for improvement, please first try to contact the maintainer directly. Look in the header of the file for the name and email address. The maintainer will take care of issues and send updates to the Vim project for distribution with Vim. If the maintainer does not respond, contact the [vim-dev][0] mailing list. # Translations Translating messages and runtime files is very much appreciated! These things can be translated: * Messages in Vim, see [src/po/README.txt][1] Also used for the desktop icons. * Menus, see [runtime/lang/README.txt][2] * Vim tutor, see [runtime/tutor/README.txt][3] * Manual pages, see [runtime/doc/\*.1][4] for examples * Installer, see [nsis/lang/\*.nsi][5] for examples The help files can be translated and made available separately. See https://www.vim.org/translations.php for examples. # How do I contribute to the project? Please have a look at the following [discussion][6], which should give you some ideas. Please also check the [develop.txt][7] helpfile for the recommended style. Often it's also beneficial to check the surrounding code for the style being used. # I have a question If you have some question on the style guide, please contact the [vim-dev][0] mailing list. For other questions please use the [Vi Stack Exchange][8] website, the [vim-use][9] mailing list or make use of the [discussion][10] feature here at github.
