Try to find in files (*.asp, *.js, *.inc) by next regex.
(\w+?)\s*?=\s*?GetDBConnection(.|\n)*?\1.]\w+?ST3 3047 crashes after a few seconds.
I know that this regex is not the best thing you’ve ever seen (it was written fast and dirty), but, I guess, its usage should not lead to crash.
Hi - It works for me in ST3 3056, on Win7
(if I put this line in one of my .js files…)
a = GetDBConnection. a.b
(Note: there are 4 spaces at the end of the line that don’t show up here or in the results below, or the regex wouldn’t have matched. It requires at least 1.)
Results:
Searching 28 files for “(\w+?)\s*?=\s*?GetDBConnection(.|\n)*?\1.]\w+?” (regex)
C:\NodeJS\Apps\xxxxxxxxxxx\src\Client\js\Role - Copy.js:
51: a = GetDBConnection. a.b
1 match in 1 file
If I then change the regex to “(\w+?)\s*?=\s*?GetDBConnectionXXX***(.|\n)?\1.]\w+?" (something it can’t possibly find)
then I get
Searching 28 files for "(\w+?)\s?=\s?GetDBConnectionXXX(.|\n)*?\1.]\w+?” (regex)
0 matches across 0 files
but no crash.
This is happening in ST3 3059 still. (Mac OS 10.9.3)
It happens on minified javascript when the file is large enough. Have not found the limits yet, but any file which exists on one very long line would likely trigger the crash.
Useful parts of the crash report for the dev:

Though to be fair my regex was also quite terrible.
I wanted to find everywhere “mapp” appeared within quotes.
This crashed the find in files:
("(?:.)mApp(?:.)")
This does not. Negating character class does not cause backtracking so I believe it is the equivalent to what I was trying to do.
("^"]mApp^"]")
