2016-10-17contrib/long-running-filter: add long running filter exampleLibravatar Lars Schneider1-1/+3
Add a simple pass-thru filter as example implementation for the Git filter protocol version 2. See Documentation/gitattributes.txt, section "Filter Protocol" for more info. Signed-off-by: Lars Schneider <larsxschneider@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-10-17convert: add filter.<driver>.process optionLibravatar Lars Schneider1-1/+154
Git's clean/smudge mechanism invokes an external filter process for every single blob that is affected by a filter. If Git filters a lot of blobs then the startup time of the external filter processes can become a significant part of the overall Git execution time. In a preliminary performance test this developer used a clean/smudge filter written in golang to filter 12,000 files. This process took 364s with the existing filter mechanism and 5s with the new mechanism. See details here: https://github.com/github/git-lfs/pull/1382 This patch adds the `filter.<driver>.process` string option which, if used, keeps the external filter process running and processes all blobs with the packet format (pkt-line) based protocol over standard input and standard output. The full protocol is explained in detail in `Documentation/gitattributes.txt`. A few key decisions: * The long running filter process is referred to as filter protocol version 2 because the existing single shot filter invocation is considered version 1. * Git sends a welcome message and expects a response right after the external filter process has started. This ensures that Git will not hang if a version 1 filter is incorrectly used with the filter.<driver>.process option for version 2 filters. In addition, Git can detect this kind of error and warn the user. * The status of a filter operation (e.g. "success" or "error) is set before the actual response and (if necessary!) re-set after the response. The advantage of this two step status response is that if the filter detects an error early, then the filter can communicate this and Git does not even need to create structures to read the response. * All status responses are pkt-line lists terminated with a flush packet. This allows us to send other status fields with the same protocol in the future.

2016-08-31graph: add support for --line-prefix on all graph-aware outputLibravatar Jacob Keller1-0/+3
Add an extension to git-diff and git-log (and any other graph-aware displayable output) such that "--line-prefix=<string>" will print the additional line-prefix on every line of output. To make this work, we have to fix a few bugs in the graph API that force graph_show_commit_msg to be used only when you have a valid graph. Additionally, we extend the default_diff_output_prefix handler to work even when no graph is enabled. This is somewhat of a hack on top of the graph API, but I think it should be acceptable here. This will be used by a future extension of submodule display which displays the submodule diff as the actual diff between the pre and post commit in the submodule project. Add some tests for both git-log and git-diff to ensure that the prefix is honored correctly. Signed-off-by: Jacob Keller <jacob.keller@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-08-17clone: recursive and reference option triggers submodule alternatesLibravatar Stefan Beller1-0/+12
When `--recursive` and `--reference` is given, it is reasonable to expect that the submodules are created with references to the submodules of the given alternate for the superproject. An initial attempt to do this was presented to the mailing list, which used flags that are passed around ("--super-reference") that instructed the submodule clone to look for a reference in the submodules of the referenced superproject. This is not well thought out, as any further `submodule update` should also respect the initial setup. When a new submodule is added to the superproject and the alternate of the superproject does not know about that submodule yet, we rather error out informing the user instead of being unclear if we did or did not use a submodules alternate. To solve this problem introduce new options that store the configuration for what the user wanted originally.
