+From c7e8b03324883760a2d6fab86ae034beb82af651 Mon Sep 17 00:00:00 2001
+From: John Drouhard <john@drouhard.dev>
+Date: Thu, 9 Jan 2025 20:34:42 -0600
+Subject: [PATCH] ctest: Allow arbitrary characters in test names of
+ CTestCostData.txt
+
+This changes the way lines in CTestCostData.txt are parsed to allow for
+spaces in the test name.
+
+It does so by looking for space characters from the end; and once two
+have been found, assumes everything from the beginning up to that
+second-to-last-space is the test name.
+
+Additionally, parsing the file should be much more efficient since there
+is no string or vector heap allocation per line. The std::string used by
+the parse function to convert the int and float should be within most
+standard libraries' small string optimization.
+
+Fixes: #26594
+
+Upstream-Status: Backport [4.0.0, 040da7d83216ace59710407e8ce35d5fd38e1340]
