168-170: Consider adding a debug log for skipped input.For debugging purposes, it might be helpful to log when input is skipped due to the terminal not being loaded yet.
if (!this.loaded) { + dlog("skipping terminal input, not loaded yet"); return; }

168-170: LGTM! The early return fixes the escape sequence printing bug.
The change correctly prevents processing terminal input data before the terminal is fully initialized. This aligns with the existing pattern in handleNewFileSubjectData which buffers data when not loaded.
Let's verify there are no other methods that need similar protection:
✅ Verification successful
The early return in handleTermData is correctly placed and other handlers are properly protected
The verification shows three handler methods in TermWrap:
handleTermData: Now has the early return when not loadedhandleNewFileSubjectData: Already has protection for unloaded state as mentioned in the reviewhandleResize: Handles window resizing which is independent of the loaded state
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Search for other terminal data handling methods that might need the loaded check
ast-grep --pattern 'class TermWrap {
$$$
handle$_($$$) {
$$$
}
$$$
}'
Length of output: 83
Script:
#!/bin/bash
# Let's try a different approach to find handler methods in TermWrap

168-170: Verify race condition handling around the loaded flag.
The loaded flag is set after loadInitialTerminalData() completes. Please ensure that any buffered input in heldData is properly processed after the terminal is loaded.
Let's check the initialization flow:
✅ Verification successful
Race condition handling for loaded flag is properly implemented
The code correctly handles buffered input through the heldData array. Here's how the race condition is prevented:
heldDatais initialized as an empty array in the constructor- In
handleNewFileSubjectData, incoming data is buffered inheldDatawhenloadedis false - The
loadedflag is set to true only afterloadInitialTerminalData()completes ininitTerminal() - Input data in
handleTermDatais properly guarded with theloadedcheck
The implementation ensures no data is lost during initialization and the terminal state remains consistent.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Search for places where heldData is processed after loading
ast-grep --pattern 'class TermWrap {
$$$
initTerminal() {
$$$
this.loaded = true;
$$$
}
$$$
}'
Length of output: 116
Script:
#!/bin/bash
# Let's first find the file content to understand the initialization flow
cat frontend/app/view/term/termwrap.ts
# Also search for any references to heldData
