--- Comment #2 from timothyjmills <thelmate...@hotmail.com> --- (In reply to Christopher Head from comment #0) > The documentation for RewriteMap prg: here > <https://httpd.apache.org/docs/2.4/rewrite/rewritemap.html#prg> left me with > a number of questions that I could not find the answer to: > * “it expects one argument via STDIN” What exactly does this mean? Each key > fed to stdin is followed by a newline? A space? Something else? There’s an > example, but that’s not very useful for those of us who don’t read Perl. > * “If there is no corresponding lookup value, the map program should return > the four-character string "NULL" to indicate this.” Does this mean there’s > no way for the mapping program to return the actual literal string NULL as > the mapped value, since trying to do so indicates failure to map instead? > * The documentation explains how stdin and stdout are used. What does Apache > do with the mapping program’s stderr? Connect it to /dev/null? Not open it > at all? Something else? > * What happens if the mapping program terminates? The text “Remember that > there is only one copy of the program, started at server startup.” suggests > that it will just stay dead and mappings will fail until Apache is > restarted, but is that actually true? > * What happens when Apache terminates? Does it send a signal to terminate > the mapping program? If so, what signal? Or does it just close stdin and > expect the mapping program to terminate when it sees EOF? Since the mapping > program is a child process of Apache, does Apache wait for it to terminate > before finishing shutdown, or does it orphan it and let PID 1 deal with it? Error reporting addresses some of the prg RewriteMap features that help you better understand the need to more clearly explain how your program handles input and behavior. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: docs-unsubscr...@httpd.apache.org For additional commands, e-mail: docs-h...@httpd.apache.org
