Victor Julien fe48920514 Remove per sgh mpm_streamcontent_maxlen variable. It was checked but never set. 14 years ago
Victor Julien 291ddd95f2 Detection engine -- mpm 
Each signature is in one mpm ctx at max, but there were 3 separate
id's in use: packet, stream, http. Merged them all into one.

Could shrink the SignatureHeader structure with 8 bytes because of this,
should lead to better caching performance.

Victor Julien 89f83e714c Introduce http_server_body keyword. 
The http_server_body content modifier modifies the previous content to inspect
the normalized (dechunked, unzipped) http_server_body. The workings are similar
to http_client_body. Additionally, a new pcre flag was introduced "/S".

To facilitate this change the signature flags field was changed to be 64 bit.

Eric Leblond 0c34a1c5e7 rewrite constants and add flag for replace

The numeric value of the flag is now used by the flag needed for replace
code.

Eric Leblond 49adc264bc Don't print message after SCMalloc failure.

message after a SCMalloc failure. They were useless as SCMalloc
already displays a message.
