Stream asset downloads to avoid OutOfMemoryException on large files (#1540 )

* Stream asset downloads to avoid OutOfMemoryException on large files ExportAssetDownloader used HttpClient.GetAsync(url, ct), which defaults to HttpCompletionOption.ResponseContentRead and buffers the entire response body into memory before returning. Downloading a large attachment therefore tried to grow a single in-memory buffer to the full file size and threw OutOfMemoryException (HttpContent.LoadIntoBufferAsync -> GrowAndWrite). Pass HttpCompletionOption.ResponseHeadersRead so the body is streamed straight to disk via CopyToAsync in bounded chunks, matching how DiscordClient already issues its requests. * Update ExportAssetDownloader.cs --------- Co-authored-by: Oleksii Holub <1935960+Tyrrrz@users.noreply.github.com>
Bump the actions group with 4 updates (#1541 )

Author	SHA1	Message	Date
Colton	799dd1ad81	Stream asset downloads to avoid OutOfMemoryException on large files (#1540 ) * Stream asset downloads to avoid OutOfMemoryException on large files ExportAssetDownloader used HttpClient.GetAsync(url, ct), which defaults to HttpCompletionOption.ResponseContentRead and buffers the entire response body into memory before returning. Downloading a large attachment therefore tried to grow a single in-memory buffer to the full file size and threw OutOfMemoryException (HttpContent.LoadIntoBufferAsync -> GrowAndWrite). Pass HttpCompletionOption.ResponseHeadersRead so the body is streamed straight to disk via CopyToAsync in bounded chunks, matching how DiscordClient already issues its requests. * Update ExportAssetDownloader.cs --------- Co-authored-by: Oleksii Holub <1935960+Tyrrrz@users.noreply.github.com>	2026-06-03 15:47:43 +03:00
