While it still fails the build-relink2 test and the quote test (long standing issues), it now fails the dry-run test. However, I can't figure out why. Basically, dry-run creates a build directory tree, and takes an 'ls -lR' snapshot of it which is stored in a file (somewhere outside the tree in question). Then, it runs a "dryrun" compile command (which should do nothing) and takes another snapshot -- the two snaps should match. (Then, it compiles "for real", takes a new 'before' snapshot, runs a dryrun link command, etc etc. But that's not important.) Here's the failure: -----------BEFORE 'SNAPSHOT'------------ .: total 163 -rw-rw-r-- 1 cwilson None 20124 Apr 9 01:58 Makefile -rw-rw-r-- 1 cwilson None 31500 Apr 9 01:58 config.log -rwxrwxr-x 1 cwilson None 28943 Apr 9 01:58 config.status -rwxrwxr-x 1 cwilson None 210074 Apr 9 03:05 libtool -rw-rw-r-- 2 cwilson None 18715 Apr 9 03:05 main.o .libs: total 206 -rwxrwxr-x 1 cwilson None 210074 Apr 9 03:03 libtool drwxrwxr-x+ 3 cwilson None 0 Apr 9 03:05 temp -----------BEFORE 'SNAPSHOT'------------ ------------AFTER 'SNAPSHOT'------------ .: total 305 -rw-rw-r-- 1 cwilson None 20124 Apr 9 01:58 Makefile -rw-rw-r-- 1 cwilson None 31500 Apr 9 01:58 config.log -rwxrwxr-x 1 cwilson None 28943 Apr 9 01:58 config.status -rwxrwxr-x 1 cwilson None 210074 Apr 9 03:05 libtool -rw-rw-r-- 2 cwilson None 18715 Apr 9 03:05 main.o .libs: total 206 -rwxrwxr-x 1 cwilson None 210074 Apr 9 03:03 libtool drwxrwxr-x+ 3 cwilson None 0 Apr 9 03:05 temp ------------AFTER 'SNAPSHOT'------------ The only difference is the "total usage" line that 'ls' prints. In the before snapshot, it says "total 163" (kB). Adding the individual file sizes, that is clearly wrong. The after snapshot gets it right: "total 305" (kB) is the sum of the individual file sizes (which are the same as in the before snapshot). This looks like a race condition or something in cygwin or fileutils(ls.exe). Has anybody seen anything like this, or is there a known file-system-related race in cygwin 1.3.22?
