J.B. Langston <[email protected]> added the comment:
Yes, it is supposed to match everything up to the closing ] in this substring:
[BigTableReader(path='/data/cassandra/data/log/logEntry_202202-e68971800b2711ecaf770d5fa3f5ae87/md-112-big-Data.db')]
Quoting from the re docs:
To match a literal ']' inside a set, precede it with a backslash, or place it
at the beginning of the set. For example, both [()[\]{}] and []()[{}] will both
match a parenthesis.
The docs don't specifically state the case of a negated set using ^, but I have
used this construction many times and never had a problem with it.
Furthermore, it is not what caused the regex to hang. That was caused by
"(?P<biggest_size>[^,]+)," and changing it to "(?P<biggest_size>.+?)," fixed
the problem.
