The Inspect find algorithm has always been challenging given the possibility that 'rows' might contain binary data. Be that as it may, two small changes have proven to dramatically improve the performance of such scans. The first involves the case wherein if no match on the 'substring' portion of a row was found, then a pointer representing the substring was increased by the length of the search string, not the better/longer substring. Thus, portions of the substring were always rescanned! The second performance boost was achieved in this way: pre-scanning each raw row for just the first character in the search string now determines if a full match is even possible. Therefore, repeated unproductive strstr calls on individual substrings within that row will be avoided. In a nutshell, 1 'if' with '}' did the trick! (now that we know a '.' + 2 spaces is squeezed to one) (everything's perfectly justified, but it's just luck) Signed-off-by: Jim Warner <james.warner@comcast.net>
COMPATIBILITY
This code is intended for use with Linux 2.6.xx, 3.x and
hopefully all future kernels.
INSTALLATION
If you are using git version of the project you need extra step.
./autogen.sh
After that, and everyone using .tar.xz version of procps-ng, can
do normal build. Read './configure --help' to select options for
your needs.
./configure
make
make install
If you have DejaGNU installed you can run optional test suite.
make check
HOW TO CONTRIBUTE
See Documentation/BUGS file.
PACKAGING
If you are a downstream maintainer (packager) for a Linux
distribution, please avoid causing troubles. This section
applies to you.
Avoid maintaining distribution specific patches. Send your
patches to upstream, where they are at least reviewed, if not
included.
Please forward bug reports. If your bug database is public and
busy enough to bother with, please make this known. Follow
Debian's lead in making the bug database easy to comment on via
email without need for an account.
For normal packages, ensure that you do not add debugging flags
to the CFLAGS variable.
