List of issues#2704 The speed of importing files to SWF via FFDec CLI has become slower

v26.0.0
We have the following repository with a CMake build: https://github.com/doodlum/SkyUI-Community. We
import AS scripts and XML files into SWF. We recently switched to v26.0.0 and the import
speed has become slower. In v25.1.3, the speed was faster. Personally, I use the Ninja
generator for parallel assembly.
Could you provide simple example that I can run on example SWF file
with the exact CLI command so I can reproduce it?
I'll try this now and give you the command. We use CMake, which automatically imports AS
and XML files into SWF files located in data/interface.
The decompilation of AS is definitely slower, I did some changes which lead to more
precise outputs which require two pass decompilation.
So if your programs for example after importing runs the decompilation part, it might be
slower.
Anyway, the code compilation (AS direct editation) and XML import should remain the same.
It seems I can't upload the 8 MB test case.
I used the following PowerShell script:
# A quick script to process all SWFs
$timer = Measure-Command {
$ffdec = "./tools/FFDec/ffdec-cli.exe"
# Creating output and copying files
Remove-Item -Path "./output" -Recurse -Force -ErrorAction SilentlyContinue
Copy-Item -Path "./data/interface" -Destination "./output" -Recurse -Force
# Getting all SWF files
$swfs = Get-ChildItem -Path "./output" -Filter "*.swf" -Recurse
foreach ($swf in $swfs) {
$name = $swf.BaseName
$xml = if (Test-Path "./source/swf/$name.xml") { "./source/swf/$name.xml" }
elseif (Test-Path "./source/swf/skyui/$name.xml") {
"./source/swf/skyui/$name.xml" }
else { $null }
$as = $null
if (Test-Path "./build/debug/_staging/AS_${name}/__Packages") { $as =
"./build/debug/_staging/AS_${name}/__Packages" }
elseif (Test-Path "./build/debug/_staging/AS_skyui_${name}/__Packages") { $as =
"./build/debug/_staging/AS_skyui_${name}/__Packages" }
if ($xml) { & $ffdec -xml2swf $xml $swf.FullName }
if ($as) { & $ffdec -config autoDeobfuscate=false,decompile=false -onerror abort
-importScript $swf.FullName $swf.FullName $as }
Write-Host "Processed: $name" -ForegroundColor Green
}
}
Write-Host "`nLead time: $($timer.TotalSeconds) sec" -ForegroundColor Cyan
What do you mean can't upload? You mean here to the issue tracker? Is there any error
message?
Error 504
Yes, I'm trying to upload a file here, it stops at about 60-70%
No, error 503

Place your version of FFDec in the ffdec/tools folder. Then run it in PowerShell:
.\process-swf.ps1
