11 years agoremote-curl: show server content on http errors
Jeff King [Fri, 5 Apr 2013 22:17:23 +0000 (18:17 -0400)]
remote-curl: show server content on http errors

If an http request to a remote git server fails, we show
only the http response code, or sometimes a custom message
for particular codes. This gives the server no opportunity
to offer a more detailed explanation of the reason for the
failure, or to give extra advice.

This patch teaches remote-curl to record and display the
body content of a failed http response. We only display such
responses when the content-type is advertised as text/plain,
as it is the most likely to look presentable on the user's
terminal (and it is hoped to be a good indication that the
message is intended for git clients, and not for a web
browser).

Each line of the new output is prepended with "remote:".
Example output may look like this (assuming the server is
configured to display such a helpful message):

  $ GIT_SMART_HTTP=0 git clone https://example.com/some/repo.git
  Cloning into 'repo'...
  remote: Sorry, fetching via dumb http is forbidden.
  remote: Please upgrade your git client to v1.6.6 or greater
  remote: and make sure that smart-http is enabled.
  error: The requested URL returned error: 403 while accessing http://localhost:5001/some/repo.git/info/refs
  fatal: HTTP request failed

For the sake of simplicity, we only record and display these
errors during the initial fetch of the ref list, as that is
the initial contact with the server and where the most
common, interesting errors happen (and there is already
precedent, as that is the only place we currently massage
http error codes into more helpful messages).

t3600: document failure of rm across symbolic links

If we have a symlink "d" that points to a directory, we
should not be able to remove "d/f". In the normal case,
where "d/f" does not exist in the index, we already disallow
this, as we only remove things that git knows about in the
index. So for something like:

  ln -s /outside/repo foo
  git add foo
  git rm foo/bar

we will properly produce an error (as there is no index
entry for foo/bar). However, if there is an index entry for
the path (e.g., because the movement is due to working tree
changes that have not yet been reflected in the index), we
will happily delete it, even though the path we delete from the
filesystem is not the same as the path in the index.

This patch documents that failure with a test.

While this is a bug, it should not be possible to cause
serious data loss with it. For any path that does not have
an index entry, we will complain and bail. For a path which
does have an index entry, we will do the usual up-to-date
content check. So even if the deleted path in the filesystem
is not the same as the one we are removing from the index,
we do know that they at least have the same content, and
that the content is included in HEAD.

That means the worst case is not the accidental loss of
content, but rather confusion by the user when a copy of a
file another part of the tree is removed. Which makes this
bug a minor and hard-to-trigger annoyance rather than a
data-loss bug (and hence the fix can be saved for a rainy
day when somebody feels like working on it).

The has_changes() function that implements "git log -S<block>" calls

around to avoid this wastage.

sides, fill_one() is called to use them.

By adding get_textconv() to diff_grep() and relieving fill_one() of
responsibility to find the textconv filter, we can avoid calling
get_textconv() twice in has_changes().

we print fatal error messages to some other file that just happens to
be opened on the now-free FD 2.  So let's not do that.

As pointed out by Eric Wong (thanks), the initial close needs to go:
