Using too much memory after disabling/enabling packages at start up on Linux #2775

Closed evandrocoan closed 5 years ago

Description

https://github.com/SublimeTextIssues/Core/issues/2724#issuecomment-479156507 Well, you've just reenabled 150ish(?)

Windows do not leak anything, while Linux does a lot.

Steps to reproduce

You can make Sublime Text bleed memory (Linux Only) at start up by:

  1. Dowload the binary file: sublime-text-3.zip (60MB)
  2. Install the packages on the file sublime-text-3.zip (60MB)
  3. Open Sublime Text and wait it load all packages
  4. Close Sublime Text
  5. Using another text editor, open the file User/Preferences.sublime-settings and add all installed third part packages to the ignored_packages setting. For your convenience, here bellow, there is a list with every single one of them:
    { "ignored_packages": [ "A File Icon", "AceJump", "ActiveViewJumpBack", "AddFolderToProject", "AdvancedCSV", "Alignment", "AlignTab", "AllAutocomplete", "AltUp", "AmxxEditor", "AmxxPawn", "ANSIescape", "AutoHotkey", "AutomaticPackageReloader", "AutoRefresh", "AutoWrap", "BBCode", "BeautifyJavaScript", "Better OCaml", "BetterCoffeeScript", "BetterFindBuffer", "BracketHighlighter", "BufferScroll", "BuildView", "CaseConversion", "ChainOfCommand", "ChangeQuotes", "ChannelRepositoryTools", "ClearCursorsCarets", "ClickableURLs", "ClipboardScopeCopy", "Color Highlighter", "ColorSchemeEditor", "ColorSchemeUnit", "ColumnSelect", "ConvertToUTF8", "CopyWithLineNumbersReloaded", "DefaultSyntax", "DeleteCurrentFile", "DistractionFreeWindow", "DocBlockr", "Dotfiles", "DuplicateSelections", "EditPreferences", "Emmet", "EvaluateInlinePython", "EvaluatePrinter", "EvaluateShell", "ExpandRegion", "ExportHtml", "ExtendedTabSwitcher", "ExtractText", "File Rename", "FileDiffs", "FileHistory", "FileRename", "FindKeyConflicts", "FixProjectSwitchRestartBug", "FixSelectionAfterIndent", "ForceRewriteSublimeSettings", "FuzzyFileNav", "GenericConfig", "GitHubMarkdownSnippets", "Glue", "GoogleSpellCheck", "HexViewer", "HighlightBuildErrors", "HighlightWords", "HighlightWordsOnSelection", "HorizontalScroll", "HungryBackspace", "Incrementor", "IncrementSelection", "IndentAndBraces", "IndentSize", "Insert Nums", "InsertNums", "InvertSelection", "JSCustom", "JumpAlongIndent", "KeepPastedTextSelected", "Language - English and Portuguese", "LanguageTool", "LaTeXSmartQuotes", "LaTeXTools", "LaTeXWordCount", "LESS", "LineEndingsUnify", "LinesMultisets", "LocalHistory", "LSP", "MarkdownPreview", "MarkdownToBBCode", "Maven", "MaxPane", "MoveText", "MultiEditUtils", "Notepad++ Color Scheme", "NumberKing", "Octave", "OpenAutoCompletion", "Origami", "OverrideAudit", "OverrideCommitCompletion", "OverrideUnpackedPackages", "PackageDev", "PackageResourceViewer", "PackagesManager", "PanelManager", "PathTranslator", "PlantUmlDiagrams", "PostScript", "PowerCursors", "PowerShell", "PrettyJSON", "PushdownParserSyntax", "PyV8", "QuickSettings", "RandomEverything", "REG", "ReIndent", "RememberCommandPaletteInput", "RemoveNonAsciiChars", "RichPlainText", "Rust Enhanced", "SassSyntax", "ScopeHunter", "SelectAll", "SelectAllSpellingErrors", "SelectUntil", "SemanticLineWrap", "SideBarEnhancements", "SideBySideCompare", "SideBySideSettings", "SQLExec", "SQLKeywordUppercase", "SQLTools", "StickySearch", "StudioChannel", "SublimeLinter", "SublimeTutorial", "Swift", "SyncViewScroll", "SyntaxManager", "TabsExtra", "TerminalShortcuts", "Terminus", "TestPlier", "TextPastry", "ToggleWords", "TOML", "Trimmer", "TypeScript", "UnitTesting", "VBScript", "ViewSettingsFreely", "Whitespace", "WordCount", "WrapPlus", "X86Assembly", "zzz A File Icon zzz", "ZzzReloadDefaultPackage", "Vintage", ] }
  6. Now open Sublime Text, and right from the beginning, it will be using 500MB of RAM memory on build 3176 and 238MB on build 3200.
  7. But, the reverse is worse. If now, you close Sublime Text and set back { "ignored_packages": [ "Vintage" ] }
  8. The next time you open Sublime Text, it will be using 860MB of RAM memory right from the start on build 3176 and 1.1GB on build 3200.
  9. And finally, if you just restart Sublime Text more one time, without touching User/Preferences.sublime-settings, it will be using only 40MB of RAM memory right from the start on build 3176 and 80MB on build 3200.
  10. All of this is only reproducible on Linux. Doing these steps on Windows, shows no problems with memory usage at all, other than just few loose mega bytes in the end of the process.

Expected behavior

No memory heavy leak when using Sublime Text on Linux.

Actual behavior

Memory heavy leak when using Sublime Text on Linux.

Keep your testing to a single OS. Trying to compare across OSes is unlikely to be helpful. There are so many different things.
