here's the only strace fragment with stat calls (with PerlSendHeaders Off)
read(3, "GET /Dispatch/foo HTTP/1.0\r\nConn"..., 4096) = 854
rt_sigaction(SIGUSR1, {SIG_IGN}, {SIG_IGN}, 8) = 0
time(NULL) = 965653681
gettimeofday({965653681, 395188}, NULL) = 0
rt_sigprocmask(SIG_BLOCK, NULL, [RT_0], 8) = 0
stat("/usr/local/apache/spinnaker/Dispatch/foo", 0xbffff7cc) = -1 ENOENT (No
such file or directory)
stat("/usr/local/apache/spinnaker/Dispatch", 0xbffff7cc) = -1 ENOENT (No
such file or directory)
stat("/usr/local/apache/spinnaker", {st_mode=S_IFDIR|0755, st_size=1024,
...}) = 0
rt_sigprocmask(SIG_BLOCK, NULL, [RT_0], 8) = 0
rt_sigaction(SIGALRM, NULL, {0x40099490, [], SA_INTERRUPT|0x4000000}, 8) = 0
dup2(15, 2) = 2
which I would guess is just apache doing apache translation things, right?
After determining the proper class->method() by parsing the uri and making
some assumptions, Dispatch.pm calls class->can(method), which does magic
things, of which I know little about the inner workings...
I was interested in somehow trying to cache known methods to avoid
successive can() calls, but I wasn't quite sure how to go about that one
yet...
does that help?
