Subject: Remove ap_chdir_file.  This function is not thread-safe, and nobody
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=db9deecf9440c7c800210ead3e67614abc992ab4;p=apache

Remove ap_chdir_file.  This function is not thread-safe, and nobody
is currently using it.  The proper way to do this, is to use the
apr_create_process API.

 Changes with Apache 2.0b1
 
+  *) Remove ap_chdir_file().  This function is not thread-safe,
+     and nobody is currently using it.  [Ryan Bloom]
+
   *) Do not try to run make depend if there are no .c files in the
      current directory, doing so makes `make depend` fail.
