"git add --ignore-errors" command fails immediately when lstat returns
an error, despite the ignore errors' flag is enabled.
There could be files that triggers an error on stat(), when other files
proceed correctly.
Issue can be reproduced when running git under Cygwin and some target files
have utf-8 long names (200+ utf chars). Windows can handle them, but all
operations on them failed under Cygwin.
Issue can not be reproduced with usual latin/numeric only names.
For example, create a file with 220 'й' letters by Windows Explorer,
then in Cygwin:
# Here and below "ййй..." means the line of й copied 220 times.
$ echo -n 'ййй...' | wc -c # check the real size
440
$ ls -la
ls: cannot access 'ййй...'$'\320': No such file or directory
-????????? ? ? ? ? ? 'ййй...'$'\320'
$ ls й*
ls: cannot access 'ййй...'$'\320': No such file or directory
$ stat й*
stat: cannot stat 'ййй...'$'\320': No such file or directory
In my perspective, it's okay to skip these problematic files when ignore
error flag is specified, but official Git terminates entire git add command
when such files come up. But with proposed patch it is the desired behavior:
$ git add --ignore-errors .
error: ййй... can only add regular files, symbolic links or git-directories
# All other files have been added correctly.
