- 1st pass at documentation with the README. - Attempt to detect trivial redirect loops. - Loosen the request parser enough to just accept URLs, so you can easily test rewrite behavior by just running volta and pasting URLs. - Alter the whitelist "negative" rule syntax to more closely match normal rules. Rename references to negative rules from "whitelist" rules, to avoid confusion.

Retain the CDB struct between lookups, only freeing when reopening the db. Big, big speed boost.

Ensure that all output is flushed immediately. Fix free() bug for non-matching rules. When creating the rules cdb, make the tmpfile in the cwd instead of /tmp. Make regular expression matches case insensitive.

Add whitelisting rules, to negate other matches if they come first in the ruleset. Remove the results set array completely, it's faster and requires less memory to do the comparisons inline.

There isn't a fast way to look up ( value exists or null ) for every piece of data that we're handed from squid -- a full table scan must be performed for each request, regardless of any indexing in place. With a decent number of rules, it's much, much slower than I anticipated, making it fairly pointless to even do parsing in ragel for speed. Trading some matching features (IPs, for now) for speed, and aiming at just doing good host/path matching at the moment, using CDB for fast host keying. Ripped out all the SQLite work, replacing it with a first round of CDB lookups. Added a ascii rulefile to cdb converter flag. Churning through the requests again! Also, fixed an off-by-one error with line extending.

1st iteration of volta actually doing something. Process the request, find the best matching rule, and rewrite the request. Without the DB queries, volta was parsing over 750k requests a second. Currently, it's down to 129.5 with 1161 rules in place. Yikes. I may need to re-evaluate some design choices here.

Clean up redundant parser actions via preprocessor macros, add a hostname->tld extractor for doing tld "wildcard" queries. Stop tracking 'parser.c' completely.

Carry the amalgamated sqlite3 around with volta, rather than requiring it to be installed on the system -- making volta a zero dependency compile. Add some more Makefile hacks to get things consistently building across OSX, FreeBSD, and Ubuntu. (There may be more later, but I'll deal with those then.)

Get the ragel line parser properly tokenizing the input lines. Add a "lines per second" timer. General cleanup and memory management.

Ansi-fy getopt function and variable declarations.

Add common archive files (LICENCE, README, etc) and a 'release' Makefile target.

Fine tuning for database initialization/upgrades.

Use pkg-config to find dependency locations, add gdb debug flags.

Check the return value of fread() when loading SQL migration files.

Groundwork for automatic database initialization and schema upgrades.

Whoops, lets not commit .o files. Fix .hgignore.

Ensure that parsing can't be subverted by requests larger than the default line buffer maximum size. If a line fits in the stack, great. If not, allocate additional memory for it instead of truncating. Add google-proftools to debug builds. Don't clean parser.c by default, so distributions don't require ragel to build. Add BSD licensing. Move helper functions out to util.c. Rename files to match function names. Start playing with sqlite API.

Dial in the Makefile and command line option parsing. Better debug output.

Initial commit of an experimental little Squid redirector.
