+
+;; Backport upstream patch from Aaron Merey which suppresses debuginfod
+;; progress messages when size is zero.  (RH BZ 2068280).
+
+Remove download size from debuginfod progress messages if unavailable
+
+Currently debuginfod progress update messages include the size of
+each download:
+
+  Downloading 7.5 MB separate debug info for /lib/libxyz.so.0
+
+This value originates from the Content-Length HTTP header of the
+transfer.  However this header is not guaranteed to be present for
+each download.  This can happen when debuginfod servers compress files
+on-the-fly at the time of transfer.  In this case gdb wrongly prints
+"-0.00 MB" as the size.
+
+This patch removes download sizes from progress messages when they are
+not available.  It also removes usage of the progress bar until
+a more thorough reworking of progress updating is implemented. [1]
