Surprised and disappointed that neither the POSIX nor PCRE2 APIs have an out-of-the-box way to work on a FILE *.

I get that they would have to do their own potentially up-to-the-size-of-the-file memory allocation for matching in the worst case, and it's easier to just make the caller deal with that problem than to come up with a good API for dealing with all those problems...

..but clearly in many cases a string matching library is in a privileged position to

know how much to stream a file incrementally and how much still needs to be held in memory while checking for matches in the entire thing, and

heuristically know when it would be better to map the file into memory instead of streaming it.

Even if it weren't for the potential performance benefits, it's clearly a common use-case and makes a whole lot of sense as a developer convenience when so many things are files, and that's before we start to consider things like fmemopen, funopen/fopencookie, and fopen_memstream.

Answer: What are PCRE limits? #fix #answer #development

What are PCRE limits?

In ModSecurity there are PCRE limits exceeded errors.

I know I can fix this by setting rules such as:

SecPcreMatchLimit 150000 SecPcreMatchLimitRecursion 150000

But, what are these rules actually doing? What does the PCRE limit recursion set to 150,000 mean? What security holes am I allowing through by setting these so high? What does the recursion and limit mean?

I know…

How-to: mod_security – PCRE limits exceeded #it #solution #answer

mod_security – PCRE limits exceeded

Just about on every request I am getting the following error:

Rule execution error - PCRE limits exceeded (-8): (null).

After a bunch of googling the only solutions seem to be

a) Add the following in your httpd.conf

SecPcreMatchLimit 150000 SecPcreMatchLimitRecursion 150000

b) Add the following to your php.ini

pcre.backtrack_limit = 10000000…

Non greedy regex matching in sed?

I’m trying to use sed to clean up lines of URLs to extract just the domain..

So from:

http://www.suepearson.co.uk/product/174/71/3816/

I want:

http://www.suepearson.co.uk/

(either with or without the trainling slash, it doesn’t matter)

I have tried:

sed 's|\(http:\/\/.*?\/\).*|\1|'

and (escaping the non greedy quantifier)

sed 's|\(http:\/\/.*\?\/\).*|\1|'
