This fixes a bug that occurs when you combine partial clone and uploadpack.packobjectshook. You can reproduce it as follows: git clone -u 'git -c uploadpack.allowfilter '\ '-c uploadpack.packobjectshook=" exec" '\ 'upload-pack' --filter=blob:none --no-local \ src.git dst.git Be careful with the line endings because this has a long quoted string as the -u argument. Note that there is an intentional space before 'exec'. Without that space, run-command.c tries to be smart and the command fails for the wrong reason. The error I get when I run this is: Cloning into '/tmp/broken'... remote: fatal: invalid filter-spec ''blob:none'' error: git upload-pack: git-pack-objects died with error. fatal: git upload-pack: aborting due to possible repository corruption on the remote side. remote: aborting due to possible repository corruption on the remote side. fatal: early EOF fatal: index-pack failed The problem is an unnecessary and harmful layer of quoting. I tried digging through the history of this function and I think this quoting was there from the start. My best guess is that it stems from a misunderstanding of what use_shell=1 means. The code seems to assume it means "arguments get joined into one big string, then fed to /bin/sh". But that is not what it means: use_shell=1 means that the first argument in the arguments array may be a shell script and if so should be passed to /bin/sh. All other arguments are passed as normal arguments. The solution is simple: never quote the filter spec. --- upload-pack.c | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) diff --git a/upload-pack.c b/upload-pack.c index 3b66bf92ba..eae1fdbc55 100644 --- a/upload-pack.c +++ b/upload-pack.c @@ -305,14 +305,7 @@ static void create_pack_file(struct upload_pack_data *pack_data, if (pack_data->filter_options.choice) { const char *spec = expand_list_objects_filter_spec(&pack_data->filter_options); - if (pack_objects.use_shell) { - struct strbuf buf = STRBUF_INIT; - sq_quote_buf(&buf, spec); - strvec_pushf(&pack_objects.args, "--filter=%s", buf.buf); - strbuf_release(&buf); - } else { - strvec_pushf(&pack_objects.args, "--filter=%s", spec); - } + strvec_pushf(&pack_objects.args, "--filter=%s", spec); } if (uri_protocols) { for (i = 0; i < uri_protocols->nr; i++) -- 2.30.0
