Made the damn thing build. And it even works from a little (rpm -qa at
least :). The main problem currently is that any time it tries to run some
external program and read it's results through a pipe - it hangs. For
example:
[mmazur@lucky 1:21 /home/mmazur]$ head -1 .rpmmacros
%_topdir %(cd ..;pwd)
[mmazur@lucky 1:17 /home/mmazur]$ strace -o LOG -f rpm --eval '%_topdir'
^C
[mmazur@lucky 1:17 /home/mmazur]$ strace -o LOG -f rpm --eval '%_topdir'
error: Macro %__spec_install_post_strip has unterminated body
error: Macro %__spec_install_post_chrpath has unterminated body
[mmazur@lucky 1:21 /home/mmazur]$
Now strace tells us something like this:
14275 __getcwd("", 1024) = 0
14275 stat("..", {st_mode=0, st_size=0, ...}) = 0
14275 chdir("/home") = 0
14275 write(1, "/home\n", 6) = 6
14274 <... poll resumed> [{fd=3, events=POLLRDNORM}, {fd=5, events=POLLRDNORM,
revents=POLLRDNORM}], 2, INFTIM) = 1
14275 exit(0) = ?
14274 gettimeofday({1088637453, 323941}, NULL) = 0
14274 --- SIGCHLD (Child exited) ---
14274 --- SIGCHLD (Child exited) ---
14274 syscall_417(0x806aca0) = 0
14274 read(3, 0x806af20, 128) = -1 EAGAIN (Resource temporarily
unavailable)
14274 fcntl(0, F_SETFL, O_RDWR|O_NONBLOCK) = 0
14274 fcntl(1, F_SETFL, O_RDWR|O_NONBLOCK) = 0
14274 fcntl(2, F_SETFL, O_RDWR|O_NONBLOCK) = 0
14274 fcntl(5, F_SETFL, O_RDWR|O_NONBLOCK) = 0
14274 read(5, "/home\n", 16384) = 6
14274 read(5, 0x8093000, 16384) = -1 EAGAIN (Resource temporarily
unavailable)
14274 poll([{fd=5, events=POLLRDNORM}], 1, 0) = 0
14274 poll(
And here's rpm from freebsd's ports:
14935 __getcwd("", 1024) = 0
14935 stat("..", {st_mode=0, st_size=0, ...}) = 0
14935 chdir("/home") = 0
14935 write(1, "/home\n", 6) = 6
14934 <... read resumed> "/home\n", 16384) = 6
14935 exit(0) = ?
14934 read(3, "", 16384) = 0
14934 --- SIGCHLD (Child exited) ---
14934 close(3)
Any hints why did the second read start returning EAGAIN instead of plain
NULL? (or at least hints where is this code)

In the year eighty five ten
God is gonna shake his mighty head
He'll either say,
"I'm pleased where man has been"
Or tear it down, and start again
