From afa3518839a013173ee90599aab6f6f5ae58f5f7 Mon Sep 17 00:00:00 2001 From: sdong Date: Wed, 3 Jun 2020 15:53:09 -0700 Subject: [PATCH] Revert "Update googletest from 1.8.1 to 1.10.0 (#6808)" (#6923) Summary: This reverts commit 8d87e9cea13b09e12d0d22d4fdebdd5bacbb5c6e. Based on offline discussions, it's too early to upgrade to gtest 1.10, as it prevents some developers from using an older version of gtest to integrate to some other systems. Revert it for now.

For example, we don't support -// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and -// repetition count ("x{5,7}"), among others. -// -// Below is the syntax that we do support. We chose it to be a -// subset of both PCRE and POSIX extended regex, so it's easy to -// learn wherever you come from. In the following: 'A' denotes a -// literal character, period (.), or a single \\ escape sequence; -// 'x' and 'y' denote regular expressions; 'm' and 'n' are for -// natural numbers. -// -// c matches any literal character c -// \\d matches any decimal digit -// \\D matches any character that's not a decimal digit -// \\f matches \f -// \\n matches \n -// \\r matches \r -// \\s matches any ASCII whitespace, including \n -// \\S matches any character that's not a whitespace -// \\t matches \t -// \\v matches \v -// \\w matches any letter, _, or decimal digit -// \\W matches any character that \\w doesn't match -// \\c matches any literal character c, which must be a punctuation -// . matches any single character except \n -// A? matches 0 or 1 occurrences of A -// A* matches 0 or many occurrences of A -// A+ matches 1 or many occurrences of A -// ^ matches the beginning of a string (not that of each line) -// $ matches the end of a string (not that of each line) -// xy matches x followed by y -// -// If you accidentally use PCRE or POSIX extended regex features -// not implemented by us, you will get a run-time failure. In that -// case, please try to rewrite your regular expression within the -// above syntax. -// -// This implementation is *not* meant to be as highly tuned or robust -// as a compiled regex library, but should perform well enough for a -// death test, which already incurs significant overhead by launching -// a child process. -// -// Known caveats: -// -// A "threadsafe" style death test obtains the path to the test -// program from argv[0] and re-executes it in the sub-process. For -// simplicity, the current implementation doesn't search the PATH -// when launching the sub-process.
