Bug ID: 28249
Summary: httpd-buildid-after-you gadget locks on wrong url
Product: elfutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: debuginfod
Assignee: unassigned at sourceware dot org
Reporter: fche at redhat dot com
CC: elfutils-devel at sourceware dot org
Target Milestone: ---
bug #27673 added a "after-you" waiting system into debuginfod, which is
intended to prevent the server from trying to service multiple concurrent
requests for the exact same debuginfo artifact. This saves wear & tear & time,
as the non-first queries can use the fdcache to fish out the result, rather
than decompressing etc. again.
Unfortunately, the code has a one-liner bug. It uses the string "/buildid" as
the unique key, not the whole URL, so it in effect limits debuginfod to
servicing exactly one buildid request at a time, which was not intentional.
02144 unique_set_reserver<string> after_you(busy_urls, url1);
url1 is the wrong key. :-(
