I have an issue with git where it hangs for 10 to 20 seconds on several
commands, including "git status". For me this is reproducible on a fresh
install of Cygwin x64 in Windows 7.
I get the feeling I am doing something wrong on my end as "git status"
is a very commonly used command, yet I see no mentions of this on the
Cygwin mailing list.
Using gdb I can see git hang in the function validate_headref on an
lstat call. validate_headref pretty much does what it says and validates
the HEAD reference file. validate_headref is called multiple times for
different candidate paths for the HEAD reference file, e.g. ".git/HEAD"
etc. For some reason the path "//HEAD" is checked and this is causing a
delay. Paths starting with "//" are treated in Cygwin as CIFS paths and
the delay comes from the timeout when Windows tries to resolve the
hostname "HEAD" to a server.
Subsequent executions of "git status" return immediately as I guess the
resolution of "HEAD" as a hostname is cached.
I don't recall having this problem previously.
Does anyone else experience this issue?
Richard
