Recompiling and uninstalling existing applications

Hi everyone,

I'm new-ish to Unix outside of being a basic user in the past. So some background on my experience level when asking this question.

My current laptop, running OS X 10.5, had Apache and PHP installed when I bought it. However I need to recompile these now to add features which weren't included 'out of the box'.

Questions:
- Do I need to do anything to 'uninstall' these existing versions of the software before the recompile?
- Do I need to delete the binaries/libraries/other directories/etc of a program I am going to be recompiling (if this isn't answered by the above question) or will this automatically be taken care of?
- How can I make sure I don't leave anything 'hanging around' when I do uninstall a program? Or recompile?
- What resources can I read to learn more about all of this and related?

Thanks!
Charles

NAME
Apache::Log -- Perl API for Apache Logging Methods Synopsis #in startup.pl #------------- use Apache::Log; my $s = Apache->server; $s->log_error("server: log_error"); $s->log_serror(Apache::LOG_MARK, Apache::LOG_ERR, 0, "log_serror logging at err level"); $s->log_serror(Apache::LOG_MARK, Apache::LOG_DEBUG, APR::ENOTIME, "debug print"); Apache::Server->log_error("routine warning"); Apache->warn("routine warning"); Apache::warn("routine warning"); Apache::Server->warn("routine warning"); #in a handler #------------ use Apache::Log; sub handler{ my $r = shift; $r->log_error("request: log_error"); $r->warn("whoah!"); my $rlog = $r->log; for my $level qw(emerg alert crit error warn notice info debug) { no strict 'refs'; $rlog->$level($package, "request: $level log level"); } # can use server methods as well my $s = $r->server; $s->log_error("server: log_error"); $r->log_rerror(Apache::LOG_MARK, Apache::LOG_DEBUG, APR::ENOTIME, "in debug"); $s->log_serror(Apache::LOG_MARK, Apache::LOG_INFO, 0, "server info"); $s->log_serror(Apache::LOG_MARK, Apache::LOG_ERR, APR::ENOTIME, "fatal error"); $s->warn('routine server warning'); } Description "Apache::Log" provides the Perl API for Apache logging methods. Constants The following constants (sorted from the most severe level to the least severe) are used in logging methods to specify the log level at which the message should be logged: o "Apache::LOG_EMERG" o "Apache::LOG_ALERT" o "Apache::LOG_CRIT" o "Apache::LOG_ERR" o "Apache::LOG_WARNING" o "Apache::LOG_NOTICE" o "Apache::LOG_INFO" o "Apache::LOG_DEBUG" For example if the current "LogLevel" is set to warning, only messages with log level of the level warning or higher (err, crit, elert and emerg) will be logged. Therefore this: $r->log_rerror(Apache::LOG_MARK, Apache::LOG_WARNING, APR::ENOTIME, "warning!"); will log the message, but this one won't: $r->log_rerror(Apache::LOG_MARK, Apache::LOG_INFO, APR::ENOTIME, "just an info"); It will be logged only if the server log level is set to info or debug. (either in the configuration file or using the "$s->loglevel()" method.) Other constants: o "Apache::LOG_LEVELMASK" used to mask off the level value, to make sure that the log level's value is within the proper bits range. e.g.: $loglevel &= LOG_LEVELMASK; o "Apache::LOG_TOCLIENT" used to give content handlers the option of including the error text in the "ErrorDocument" sent back to the client. When "Apache::LOG_TOCLIENT" is passed to "log_rerror()" the error message will be saved in the $r's notes table, keyed to the string "error-notes", if and only if the severity level of the message is "Apache::LOG_WARNING" or greater and there are no other "error-notes" entry already set in the request record's notes table. Once the "error-notes" entry is set, it is up to the error handler to determine whether this text should be sent back to the client. For example: $r->log_rerror(Apache::LOG_MARK, Apache::LOG_ERR|Apache::LOG_TOCLIENT, APR::ENOTIME, "request log_rerror"); now the log message can be retrieved via: $r->notes->get("error-notes"); Remember that client generated text streams sent back to the client MUST be escaped to prevent CSS attacks. o "Apache::LOG_STARTUP" is set only during the startup. Server Logging Methods "$s->log_error()" $s->log_error(@message); just logs the supplied message. For example: $s->log_error("running low on memory"); "$s->log_serror()" log_serror($file, $line, $level, $status, @message); where: * $file The file in which this function is called * $line The line number on which this function is called * $level The level of this error message * $status The status code from the previous command * @message The log message This function provides a fine control of when the message is logged, gives an access to built-in status codes. For example: $s->log_serror(Apache::LOG_MARK, Apache::LOG_ERR, 0, "log_serror logging at err level"); $s->log_serror(Apache::LOG_MARK, Apache::LOG_DEBUG, APR::ENOTIME, "debug print"); "$s->log()" my $slog = $s->log; returns a handle which can be used to log messages of different level. See the next entry. emerg(), alert(), crit(), error(), warn(), notice(), info(), debug() $s->log->emerg(@message); after getting the log handle with "$s->log", use these methods to control when messages should be logged. For example: my $slog = $s->log; $slog->debug("just ", "some debug info"); $slog->warn(@warnings); $slog->crit("dying"); Request Logging Methods "$r->log_error()" $r->log_error(@message); logs the supplied message (similar to "$s->log_error"). For example: $r->log_error("the request is about to end"); the same as "$s->log_error". "$r->log_rerror()" log_rerror($file, $line, $level, $status, @message); same as "$s->log_rerror". For example: $s->log_rerror(Apache::LOG_MARK, Apache::LOG_ERR, 0, "log_rerror logging at err level"); $s->log_rerror(Apache::LOG_MARK, Apache::LOG_DEBUG, APR::ENOTIME, "debug print"); "$r->log()" my $rlog = $r->log; Similar to "$s->log()" the emerg(), alert(), crit(), error(), warn(), notice(), info(), debug() methods Similar to the server's log functions with the same names. For example: $rlog->debug("just ", "some debug info"); $rlog->warn(@req_warnings); $rlog->crit("dying"); General Functions "Apache::LOG_MARK()" my($file, $line) = Apache::LOG_MARK(); Though looking like a constant, this is a function, which returns a list of two items: "(__FILE__, __LINE__)", i.e. the file and the line where the function was called from. Aliases "$s->warn()" $s->warn(@warnings); is the same as: $s->log_error(Apache::LOG_MARK, Apache::LOG_WARNING, 0, @warnings) For example: $s->warn('routine server warning'); "Apache->warn()" "Apache::warn()" Apache->warn(@warnings); perl v5.8.0 2002-08-14 LOG(1)
