From d3eccbcd8b9bc51b1a940325509b9508c3697391 Mon Sep 17 00:00:00 2001 From: Andrew Productengine Date: Mon, 13 Dec 2010 13:17:48 +0200 Subject: STORM-229 FIXED Fixed long loading times and stalling of Viewer while loading big scripts or pasting a lot of text into script. The bug was fixed by Satomi Ahn. Here is the description of what causes the problem from her comment in ticket: "Disabling the loading of syntax keywords in LLScriptEdCore::postBuild() removes the freeze (and with it: syntax highlighting). So it obviously comes from the parsing of the text. I also noticed something else: by adding a llwarn in LLTextEditor::updateSegments(), I saw that this function was called a lot of times when loading a script, roughly once for each line in the script (naively I would have thought only necessary to update when finished... or to only update the new line). My llwarn was in the "if (mReflowIndex < S32_MAX && mKeywords.isLoaded())", which means that, at each call, the text is actually parsed for all keywords... so the parsing of the script becomes quadratic instead of linear!!!" - To fix this, Satomi added a flag depending on which parsing is disabled when it is not necessary. --- indra/llui/lltexteditor.cpp | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'indra/llui/lltexteditor.cpp') diff --git a/indra/llui/lltexteditor.cpp b/indra/llui/lltexteditor.cpp index 94bf716e7d..5a46c7c98e 100644 --- a/indra/llui/lltexteditor.cpp +++ b/indra/llui/lltexteditor.cpp @@ -277,6 +277,8 @@ LLTextEditor::LLTextEditor(const LLTextEditor::Params& p) : mHPad += UI_TEXTEDITOR_LINE_NUMBER_MARGIN; updateRects(); } + + mParseOnTheFly = TRUE; } void LLTextEditor::initFromParams( const LLTextEditor::Params& p) @@ -324,8 +326,10 @@ void LLTextEditor::setText(const LLStringExplicit &utf8str, const LLStyle::Param blockUndo(); deselect(); - + + mParseOnTheFly = FALSE; LLTextBase::setText(utf8str, input_params); + mParseOnTheFly = TRUE; resetDirty(); } @@ -1367,6 +1371,7 @@ void LLTextEditor::pastePrimary() // paste from primary (itsprimary==true) or clipboard (itsprimary==false) void LLTextEditor::pasteHelper(bool is_primary) { + mParseOnTheFly = FALSE; bool can_paste_it; if (is_primary) { @@ -1450,6 +1455,7 @@ void LLTextEditor::pasteHelper(bool is_primary) deselect(); onKeyStroke(); + mParseOnTheFly = TRUE; } @@ -2385,7 +2391,7 @@ void LLTextEditor::loadKeywords(const std::string& filename, void LLTextEditor::updateSegments() { - if (mReflowIndex < S32_MAX && mKeywords.isLoaded()) + if (mReflowIndex < S32_MAX && mKeywords.isLoaded() && mParseOnTheFly) { LLFastTimer ft(FTM_SYNTAX_HIGHLIGHTING); // HACK: No non-ascii keywords for now -- cgit v1.2.3
