Bug ID: 395434
Summary: valgrind XML output should setlinebuf() to facilitate
online use
Product: valgrind
Version: 3.14 SVN
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: jrei...@bitwagon.com
Target Milestone: ---
The XML output from valgrind tools should be written to a stdio FILE that has
setlinebuf() so that the output for each error appears immediately, yet with
reasonable buffering efficiency. Currently the output is buffered to the
default block size (4KB or 8KB), so recent errors often are delayed as viewed
by another process which is watching the XML output. This inhibits "online"
use, which can be handy for debugging. (Motivated by a recent request in
[valgrind-developers] mailing list.)
