th dashes are
legal.
* Took away the prepend of /tmp to the preserve filename. Now the
user can specify whatever local path they want. I figure that
filesystem permissions will prevent people from doing anything
really dumb, and people have requested this change.
* Better checking in the extract_cookie routine. Before, it could
segfault if a person specified "c" but didn't define MySQLWhichCookie.
* Some code reorg/renaming for clarity and to support the new direction
of database inspecificity. More to come.
* Simplified error messages.
* Table creation now uses safe_mysql_query and checks the result.
* Config directives used to begin with MySQL, now begin with LogSQL.
This is for database inspecificity. In your httpd.conf just do
a search-and-replace.
* More robust table-creation code with error checking. [The race condition
that several users have reported may still exist, but this will go a long
way toward debugging the condition.]
* Fixed bug whereby a MySQL connection was abandoned on reopen; the old
connection is now properly closed first.
* Minor: remind user not to set createtables when massvirtual is on.
* If Apache started but MySQL was unavailable, the module would do
everything it was supposed to (preserve entries, etc.) but not notify
the sysadmin. Added a log message to alert sysadmin if MySQL is
unreachable at startup.
* New config key 'I' to extract & log unique_id, provided by mod_unique_id.
unique_id is the key that links separate tables (access, notes, etc.)
* Migrated to the Artistic License (as used by Perl).
* Moved table creation into its own callable function
* Robustifying table creation
* In make_combined_log.pl, backtick-quoted the table name and added an
order-by clause within the select statement.
* TCP port number for db connection is now configurable using LogSqlTCPPort
* New directive LogSQLForcePreserve sends all log entries directly to the
preserve file and *entirely bypasses* the db. Useful for debugging, but
can be dangerous if you forget it's set!
* Table names are now quoted in all cases with backticks in order to permit
names containing dashes (since many hostnames contain dashes).
* The request_method field is now created as a varchar(10) instead of (6),
after it was pointed out to me that some methods can be longer than 6.
* New directive LogSQLMachineID sets a string identifier for the webserver
machine. This is useful if you have a cluster of many webservers and you
want to differentiate between them in the logs: you can tell which log
entries came from each machine and thereby analyze your loadbalacing
performance. Activate with the TransferLogFormat character 'M'. Much
faster than doing some sort of wacky IP addr lookup via local_addr().
* Added an alternative way of logging cookies. If you need to associate
multiple cookies with each request, the new way involves using
LogSQLWhichCookies (note the plural) and LogSQLCookieLogTable.
* Removed LogSQLRefererIgnore references, since it was never actually
activated anyway and the idea probably was of minimal value.
1.16:
* Moved all the user DEFINEs inside the .c file -- splitting them
between the C and the Makefile was getting just too cumbersome.
* A new MySQLPreserveFile runtime config directive. In the last
version the name of the preserve-file was hardcoded and therefore
global across all Apache virtual servers. Now the user can configure
this on a per-virthost basis. It defaults to a hardcoded value
if the user does not define it. The module *always* prepends /tmp/
to the user-supplied value for security reasons.
* A new MySQLSocketFile runtime config directive. In the last
version the name of the MySQL socket was hardcoded. Now the user
can configure this at Apache runtime. However, it is a global
setting (set once) just like the rest of the actual database info is.
It defaults to a hardcoded value if the user does not define it.
* A new MySQLCreateTables runtime config directive. Module can now
create the access table on-the-fly. Table creation takes place
during the virtual server's first request and is flagged after that to
avoid repetition.
* A new MySQLMassVirtualHosting runtime config directive. This flag
currently only activates a single feature: each virtual server gets
its very own dynamically-determined table prefixed 'access_' with the
server's name following. It also implies MySQLCreateTables On, and
obviates the need for MySQLTransferLogTable.
* escape_query (was mysql_escape_log) is now called on every item
rather than first checking to see if it needs to be called, which
was probably a big waste of time. Furthermore the routine now
uses a native MySQL API call to do the escaping instead of doing
this 'manually.' It attempts to use the charset-respectful MySQL
call first, but falls back on a more generic call if the MySQL
server is unavailable (e.g. if it goes offline).
* Open preserve file with pfopen instead of regular fopen to
take advantage of pool structure.
* As forewarned, I finally got rid of the code to support separate
Referer and Agent logs.
* Finally brought the make process up-to-date with the way Apache
likes modules to be done.
* MySQLWhichCookie is now configurable on a per-virtualserver basis.
Before it was single-shot global only.
* Reduced sleep time on a retry to 1/4 second from 1/2 second.
* Confirmed that this module will compile with -pedantic ... but not
with -ansi. :-)
1.15:
* Vastly improved error reporting is a lot clearer about lost db
connections, etc. Some unreachable code has been corrected.
* The way that query-retries and openlink-retries are handled has
been tweaked and improved.
* Missed database entries are now preserved for later inclusion. This
file is not held open but is closed after each use, so it's safe
to delete while Apache is running.
* Now each child instantiates its MySQL link upon birth rather than
waiting for its first request.
1.14:
* Improved the apxs instructions based on user feedback, including the
mysql.sock define issue.
* Corrected the INSTALL example directives to the new format.
* Some improvements to 'make distro'
1.13:
* Now use ap_get_server_name() in extract_virtual_host() to fix the
instances where mass-virtual-hosting sites were getting the wrong
server-name written to the log.
* Now use mysql_real_connect() instead of mysql_connect(). The
latter's use was deprecated and did not work in MySQL 4.
* There is now a DEFINE for the socket name. This is used by the
mysql_real_connect() function and is relevant only if the db resides
on localhost. It is irrelevant if the db resides on a networked
machine and is ignored in that case (although it still must be defined
for the connect to work).
1.12:
* Added a mysql_close() call to get rid of those annoying MySQL
complaints every time an httpd child process terminates. (Apache
1.3 or later.)
* Considerable code reorganization and cleanup.
1.11:
* Completely re-worked the cookie code. Now the user can instruct
mod_log_mysql which cookie (out of many available) to log. (See
the online directives documentation and FAQ.)
* New config capability: 'H' to log the request protocol
(e.g. HTTP/1.1)
* New config capability: 'm' to log the request method
(e.g. GET, PUT, etc.)
* New config capabilities: 'z' 'q' & 'Q' to log SSL_CIPHER,
SSL_CIPHER_USEKEYSIZE and SSL_CIPHER_ALGKEYSIZE. These require
openssl and glibc-devel to be installed. (See the online
directives documentation and FAQ.)
* Fixed a bug in make_combined_log.pl that caused it to generate
incorrect output on single-digit days.
* Fixed make_combined_log.pl to use the data logged by 'H' and 'm'.
* Migrated all log_error calls to the newer ap_log_error call.
* Added a DEBUG define to activate certain debugging/informational
error-log messages (for devel purposes).
* I apologize for the inconvenience this may cause: I decided to
rename the runtime configuration directives so that they would
make more sense and group together with a "MySQL" prefix. They
are now:
MySQLRefererLogTable
The MySQL table that holds the referer log
MySQLAgentLogTable
The MySQL table that holds the agent log
MySQLTransferLogTable
The MySQL table that holds the transfer log
MySQLTransferLogFormat
Instruct the module what information to log to the MySQL transfer log
MySQLRefererIgnore
List of referers to ignore, accesses that match will not be logged to
MySQL
MySQLRequestIgnore
List of URIs to ignore, accesses that match will not be logged to MySQL
MySQLRemhostIgnore
List of remote hosts to ignore, accesses that match will not be logged
to MySQL
MySQLDatabase
The name of the MySQL database for logging
MySQLWhichCookie
The CookieName that you want logged when using the 'c' config directive
MySQLLoginInfo
The MySQL host, user-id and password for logging
You'll need to just do a search-and-replace in your httpd.conf...
Again, I'm sorry, but it really is better this way.
* Cleaned up the summaries that get output on "httpd -L"
* Expanded the enclosed access_log.sql file to support every column type
that mod_log_mysql provides -- delete the ones that you don't need.
* Some cleanup of the Makefile - pay attention to the settings
* Made the MySQLTransferLogFormat default "AbHhmRSsTUuv" to incorporate the
new column types and sort the characters alphabetically for reading ease.
1.10:
* New config directive/capability: 'c' to log mod_usertrack cookies.
* Some code cleanup and commenting.
* Referer and User-Agent now set to want_orig=1 ( a very minor detail )
* Corrected mysql_escape_log to properly check for and escape strings
with `dangerous' characters. It appears that it was doing this
incorrectly before.
* Deleted log_mysql_child(), a function that was never called.
1.09:
* If the MySQL INSERT causes an error, we re-try that INSERT after
a short 1/2-second sleep just to make sure it wasn't due to a
network glitch or other gremlin.
* Made the default log format: huSUsbTvRA. This provides everything
required to reproduce Combined Log Format data.
1.08:
* Now log a single '-' (instead of a zero-length string) when
User-Agent is blank. This is similar to what Apache does in its own
logs. (Should have caught this when I did the same thing for
Referer.)
* Separated documentation into README, INSTALL, CHANGELOG, etc. as
appropriate.
1.07:
* Renamed TransferIgnore directive to RequestIgnore, since that's
really a more specific and accurate description of what that
directive means.
* Now log a single '-' (instead of a zero-length string) when Referer
is blank. This is similar to what Apache does in its own logs.
1.06:
* Added 'R' and 'A' options to TransferLogMySQLFormat so that we now
can log Referer and Agent respectively.
* Code cleanup: all compilation warnings are now gone, even with -Wall.
(They were mainly "const" issues that needed straightening up.)
* Added RemhostIgnore configuration directive to permit non-logging of
any request coming from a specific host, e.g. a local network
machine, etc.
* Now use the non-obsolete ap_compat.h headerfile instead of
compat.h. This simply gets rid of a compilation warning, nothing
more.
* Now include a headerfile (http_log.h) that was missing. Its
absence was giving us this warning message: "implicit declaration of
function `ap_log_error_old'."
* For numerics that Apache customarily logs as a "-" we now log a zero
instead of a -1. This seems to be more intuitive, e.g. in the
"bytes_sent" column.
* We now have a Makefile and a full "make" process that does all
the real work.
* New maintainer.
1.05:
* Removed some redundant code, after being noted by Vivek Khera that
this code doesn't even get called with the current apache code. It
can be done in apache 1.3, but it works ok without it anyway.
* Added the necessary include file to make the module compile under
Apache 1.3b6. I haven't actually tested that it works, though.
indent'd the code.
1.04:
* Rearranged some code to allow for a successful apache 1.3beta
compilation. Please note that this is *untested*, I only got it to
compile, I haven't actually tried to run apache 1.3.
1.03:
* Changed the check for 'mysql server has gone away' to be case
insensitive, so that it works with MySQL 3.21
* Changed the behavior so that a link isn't established until it's
necessary (e.g., if SQL logging is used for one virtual IP, a link
won't be opened until there's an access to that IP).
1.02:
* Managed to track down that segmentation fault that occured once, and
fixed it. No known bugs now exist.
1.01:
* Segmentation fault in case of certain parameters lacking fixed.
* Worked around the SIGPIPE signal that's sent in certain events from
* mysql_query(). Minor modifications
