Bug ID: 55833
Summary: mod_disk_cache reads from closed files
Product: Apache httpd-2
Version: 2.4.6
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: mod_cache_disk / mod_disk_cache
Assignee: [email protected]
Reporter: [email protected]
mod_disk_cache reads and closes hdrs.fd in recall_headers() but clearly closes
hdrs.fd in open_entity (the immediately preceding callback).
On unix, the read from the closed file seems to be tolerated because they are
open with buffering, but I think this is not intended.
IIUC, hdrs.fd should be left open from branches that return OK, and closed on
the others. Or the relatively short data should be buffered explicitly
somewhere in memory / mod_disk_cache.
