Bug ID: 28034
Summary: debuginfod server: preserve + etc. elements in
incoming webapi 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: ---
When requesting some source files, some URL-inconvenient chars sometimes pop
up. Example from f33 libstdc++:
/buildid/44d8485cb75512c2ca5c8f70afbd475cae30af4f/source/usr/src/debug/gcc-10.3.1-1.fc33.x86_64/obj-x86_64-redhat-linux/x86_64-redhat-linux/libstdc++-v3/src/c++11/../../../../../libstdc++-v3/src/c++11/condition_variable.cc
As this URL is passed into debuginfod's handler_cb, it appears that the + signs
are helpfully unescaped to spaces by libmicrohttpd, which 'course breaks
everything. We need to suppress this HTTP URL processing step. Also worth
checking that %HEX decoding is also suppressed.
(.... alternately, we could change the client to urlencode such identifiers
.... and change the webapi to spell this out. But I hope that's not
necessary.)
