Solution: Add tests. (Yegappan Lakshmanan, closes vim/vim#5892) https://github.com/vim/vim/commit/ee4e0c1e9a81cb5d96e0060203a9033c2f28588e Omit Test_range() change: reverted in patch 8.2.0615. Cherry-pick Test_z_no_space_before_xxx() from patch 8.2.0195. Cherry-pick Test_reverse_sort_uniq() change from patch 8.2.0183. Make uniq() error behavior consistent with sort(). Cherry-pick Test_set_ttytype() change from patch 8.1.1826. Cherry-pick quickfix checks from patch 8.1.2373 to test_preview.vim. Test_viminfo_error() is applicable. Cherry-pick E1058 from patch 8.2.0149 and port Test_deep_nest() to Lua. --- test/functional/vimscript/eval_spec.lua | 75 +++++++++++++++++++++++++++++++++ 1 file changed, 75 insertions(+) (limited to 'test/functional/vimscript/eval_spec.lua') diff --git a/test/functional/vimscript/eval_spec.lua b/test/functional/vimscript/eval_spec.lua index 0c2ca8de78..65ac5b8c80 100644 --- a/test/functional/vimscript/eval_spec.lua +++ b/test/functional/vimscript/eval_spec.lua @@ -10,11 +10,13 @@ -- test/functional/vimscript/functions_spec.lua local helpers = require('test.functional.helpers')(after_each) +local Screen = require('test.functional.ui.screen') local lfs = require('lfs') local clear = helpers.clear local eq = helpers.eq local exc_exec = helpers.exc_exec +local exec = helpers.exec local eval = helpers.eval local command = helpers.command local write_file = helpers.write_file @@ -144,3 +146,76 @@ describe('List support code', function() end end) end) + +-- oldtest: Test_deep_nest() +it('Error when if/for/while/try/function is nested too deep',function() + clear() + local screen = Screen.new(80, 24) + screen:attach() + meths.set_option('laststatus', 2) + exec([[ + " Deep nesting of if ... endif + func Test1() + let @a = join(repeat(['if v:true'], 51), "\n") + let @a ..= "\n" + let @a ..= join(repeat(['endif'], 51), "\n") + @a + let @a = '' + endfunc + + " Deep nesting of for ... endfor + func Test2() + let @a = join(repeat(['for i in [1]'], 51), "\n") + let @a ..= "\n" + let @a ..= join(repeat(['endfor'], 51), "\n") + @a + let @a = '' + endfunc + + " Deep nesting of while ... endwhile + func Test3() + let @a = join(repeat(['while v:true'], 51), "\n") + let @a ..= "\n" + let @a ..= join(repeat(['endwhile'], 51), "\n") + @a + let @a = '' + endfunc + + " Deep nesting of try ... endtry + func Test4() + let @a = join(repeat(['try'], 51), "\n") + let @a ..= "\necho v:true\n" + let @a ..= join(repeat(['endtry'], 51), "\n") + @a + let @a = '' + endfunc + + " Deep nesting of function ... endfunction + func Test5() + let @a = join(repeat(['function X()'], 51), "\n") + let @a ..= "\necho v:true\n" + let @a ..= join(repeat(['endfunction'], 51), "\n") + @a + let @a = '' + endfunc + ]]) + screen:expect({any = '%[No Name%]'}) + feed(':call Test1()') + screen:expect({any = 'E579: '}) + feed('') + screen:expect({any = '%[No Name%]'}) + feed(':call Test2()') + screen:expect({any = 'E585: '}) + feed('') + screen:expect({any = '%[No Name%]'}) + feed(':call Test3()') + screen:expect({any = 'E585: '}) + feed('') + screen:expect({any = '%[No Name%]'}) + feed(':call Test4()') + screen:expect({any = 'E601: '}) + feed('') + screen:expect({any = '%[No Name%]'}) + feed(':call Test5()') + screen:expect({any = 'E1058: '}) +end) -- cgit From 813476bf7291dfaf9fc0ef77c9f53a07258a3801 Mon Sep 17 00:00:00 2001 From: Sean Dewar Date: Tue, 30 Aug 2022 23:13:52 +0100 Subject: fix(exceptions): restore `did_throw` (#20000) `!did_throw` doesn't exactly imply `!current_exception`, as `did_throw = false` is sometimes used to defer exception handling for later (without forgetting the exception). E.g: uncaught exception handling in `do_cmdline()` may be deferred to a different call (e.g: when `try_level > 0`). In #7881, `current_exception = NULL` in `do_cmdline()` is used as an analogue of `did_throw = false`, but also causes the pending exception to be lost, which also leaks as `discard_exception()` wasn't used. It may be possible to fix this by saving/restoring `current_exception`, but handling all of `did_throw`'s edge cases seems messier. Maybe not worth diverging over. This fix also uncovers a `man_spec.lua` bug on Windows: exceptions are thrown due to Windows missing `man`, but they're lost; skip these tests if `man` isn't executable. --- test/functional/vimscript/eval_spec.lua | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) (limited to 'test/functional/vimscript/eval_spec.lua') diff --git a/test/functional/vimscript/eval_spec.lua b/test/functional/vimscript/eval_spec.lua index 65ac5b8c80..d4fa7afe89 100644 --- a/test/functional/vimscript/eval_spec.lua +++ b/test/functional/vimscript/eval_spec.lua @@ -219,3 +219,31 @@ it('Error when if/for/while/try/function is nested too deep',function() feed(':call Test5()') screen:expect({any = 'E1058: '}) end) + +describe("uncaught exception", function() + before_each(clear) + after_each(function() + os.remove('throw1.vim') + os.remove('throw2.vim') + os.remove('throw3.vim') + end) + + it('is not forgotten #13490', function() + command('autocmd BufWinEnter * throw "i am error"') + eq('i am error', exc_exec('try | new | endtry')) + + -- Like Vim, throwing here aborts the processing of the script, but does not stop :runtime! + -- from processing the others. + -- Only the first thrown exception should be rethrown from the :try below, though. + for i = 1, 3 do + write_file('throw' .. i ..
