From 53eff9792f1ae5ece49dfe79b40d1d73ae530688 Mon Sep 17 00:00:00 2001 From: Vincent Petry Date: Mon, 11 Jan 2016 12:38:13 +0100 Subject: [PATCH] Check the quota on the actual file's storage in dav quota plugin Fix quota plugin to use the correct file name when chunking When chunking, the file name is the compound name, so need to convert it to the correct final file name before doing the free space check. This ensures that in the case of shared files, the correct storage is used for the quota check. --- apps/dav/lib/connector/sabre/quotaplugin.php | 17 ++- .../unit/connector/sabre/quotaplugin.php | 109 +++++++++++++++++- 2 files changed, 116 insertions(+), 10 deletions(-) diff --git a/apps/dav/lib/connector/sabre/quotaplugin.php b/apps/dav/lib/connector/sabre/quotaplugin.php index a02827da49..b1c3bbfbbb 100644 --- a/apps/dav/lib/connector/sabre/quotaplugin.php +++ b/apps/dav/lib/connector/sabre/quotaplugin.php @@ -95,12 +95,14 @@ class QuotaPlugin extends \Sabre\DAV\ServerPlugin { $req = $this->server->httpRequest; if ($req->getHeader('OC-Chunked')) { $info = \OC_FileChunking::decodeName($newName); - $chunkHandler = new \OC_FileChunking($info); + $chunkHandler = $this->getFileChunking($info); // subtract the already uploaded size to see whether // there is still enough space for the remaining chunks $length -= $chunkHandler->getCurrentSize(); + // use target file name for free space check in case of shared files + $uri = rtrim($parentUri, '/') .
