X-Git-Tag: v1.5.3.7~3
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=67d232426b8858b31e54a9b6a5a90916690d1153;p=git.git

cvsimport: fix usage of cvsimport.module

There were two problems:

  1. We only look at the config variable if there is no module
     given on the command line. We checked this by comparing
     @ARGV == 0. However, at the time of the comparison, we
     have not yet parsed the dashed options, meaning that
     "git cvsimport" would read the variable but "git
     cvsimport -a" would not. This is fixed by simply moving
     the check after the call to getopt.

  2. If the config variable did not exist, we were adding an
     empty string to @ARGV. The rest of the script, rather
     than barfing for insufficient input, would then try to
     import the module '', leading to rather confusing error
     messages. Based on patch from Emanuele Giaquinta.
