Anoop Saldanha 988c92f71c http user agent keyword + mpm + inspection + fast pattern support added 13 years ago
Victor Julien af4e480163 Fix __WORDSIZE redeclaration warning on Windows builds. 14 years ago
Victor Julien d908e707d7 profiling: add per lock location profiling 
Add profiling per lock location in the code. Accounts how often a
lock is requested, how often it was contended, the max number of
ticks spent waiting for it, avg number of ticks waiting for it and
the total ticks for that location.

Added a new configure flag --enable-profiling-locks to enable this
feature.

Anoop Saldanha 09313cf9bd Support http stat code detection engine, fast pattern(mpm engine included). Fix http stat code setup function. Fix pcre option for stat msg keyword. With this the pcre options for server_body is Q, for stat_msg is Y and for stat_code is S 14 years ago
Victor Julien 4cbaeb408c Add functions to determine whether a path is absolute or relative. 14 years ago
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.

Victor Julien 3693a7a9ee Profiling: add accounting for several detection phases. 14 years ago
Victor Julien 820b0ded82 Add per packet profiling. 
Per packet profiling uses tick based accounting. It has 2 outputs, a summary
and a csv file that contains per packet stats.

Stats per packet include:
 1) total ticks spent
 2) ticks spent per individual thread module
 3) "threading overhead" which is simply calculated by subtracting (2) of (1).

A number of changes were made to integrate the new code in a clean way:
a number of generic enums are now placed in tm-threads-common.h so we can
include them from any part of the engine.

Code depends on --enable-profiling just like the rule profiling code.

New yaml parameters:

profiling:
  # packet profiling
  packets:

    # Profiling can be disabled here, but it will still have a
    # performance impact if compiled in.
    enabled: yes
    filename: packet_stats.log
    append: yes

    # per packet csv output
    csv:

      # Output can be disabled here, but it will still have a
      # performance impact if compiled in.
      enabled: no
      filename: packet_stats.csv

Example output of summary stats:

IP ver   Proto   cnt        min      max          avg

Per Thread module stats:

Thread Module              IP ver   Proto   cnt        min      max          avg
