[PATCH v6 03/10] git_connect: remove artificial limit of a remote command

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since day one, function git_connect() had a limit on the command line of
the command that is invoked to make a connection. 7a33bcbe converted the
code that constructs the command to strbuf. This would have been the
right time to remove the limit, but it did not happen. Remove it now.

git_connect() uses start_command() to invoke the command; consequently,
the limits of the system still apply, but are diagnosed only at execve()
time. But these limits are more lenient than the 1K that git_connect()
imposed.
