Subject: [PATCH] Merge r1878280 from trunk:
|
|
|
|
mod_proxy_http: don't strip EOS when spooling request body to file.
|
|
|
|
To prevent stream_reqbody() from sending the FILE and FLUSH bucket in separate
|
|
brigades, and thus apr_file_setaside() to trigger if network congestion occurs
|
|
with the backend, restore the EOS in spool_reqbody_cl() which was stripped
|
|
when spooling the request body to a file.
|
|
|
|
Until APR r1878279 is released (and installed by users), apr_file_setaside()
|
|
on a temporary file (mktemp) will simply drop the file cleanup, leaking the
|
|
fd and inode..
|
|
|
|
This fixes BZ 64452.
