2016-12-06docs: warn about possible '=' in clean/smudge filter process valuesLibravatar Lars Schneider2-12/+16
A pathname value in a clean/smudge filter process "key=value" pair can contain the '=' character (introduced in edcc858). Make the user aware of this issue in the docs, add a corresponding test case, and fix the issue in filter process value parser of the example implementation in contrib.

2016-11-11t0021: remove debugging cruftLibravatar Junio C Hamano1-2/+1
The redirection of the standard error stream to a temporary file is a leftover cruft during debugging. Remove it. Besides, it is reported by folks on the Windows that the test is flaky with this redirection; somebody gets confused and this merely-redirected-to file gets marked as delete-pending by git.exe and makes it finish with a non-zero exit status when "git checkout" finishes. Windows folks may want to figure that one out, but for the purpose of this test, it shouldn't become a show-stopper. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-10-17convert: add filter.<driver>.process optionLibravatar Lars Schneider2-3/+633
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.

2016-09-01submodule: avoid auto-discovery in prepare_submodule_repo_env()Libravatar Junio C Hamano1-0/+35
The function is used to set up the environment variable used in a subprocess we spawn in a submodule directory. The callers set up a child_process structure, find the working tree path of one submodule and set .dir field to it, and then use start_command() API to spawn the subprocess like "status", "fetch", etc. When this happens, we expect that the ".git" (either a directory or a gitfile that points at the real location) in the current working directory of the subprocess MUST be the repository for the submodule. If this ".git" thing is a corrupt repository, however, because prepare_submodule_repo_env() unsets GIT_DIR and GIT_WORK_TREE, the subprocess will see ".git", thinks it is not a repository, and attempt to find one by going up, likely to end up in finding the repository of the superproject. In some codepaths, this will cause a command run with the "--recurse-submodules" option to recurse forever. By exporting GIT_DIR=.git, disable the auto-discovery logic in the subprocess, which would instead stop it and report an error. The test illustrates existing problems in a few callsites of this function. Without this fix, "git fetch --recurse-submodules", "git status" and "git diff" keep recursing forever.

2016-08-31allow do_submodule_path to work even if submodule isn't checked outLibravatar Jacob Keller1-0/+127
Currently, do_submodule_path will attempt locating the .git directory by using read_gitfile on <path>/.git. If this fails it just assumes the <path>/.git is actually a git directory. This is good because it allows for handling submodules which were cloned in a regular manner first before being added to the superproject. Unfortunately this fails if the <path> is not actually checked out any longer, such as by removing the directory. Fix this by checking if the directory we found is actually a gitdir. In the case it is not, attempt to lookup the submodule configuration and find the name of where it is stored in the .git/modules/ directory of the superproject. If we can't locate the submodule configuration, this might occur because for example a submodule gitlink was added but the corresponding .gitmodules file was not properly updated. A die() here would not be pleasant to the users of submodule diff formats, so instead, modify do_submodule_path() to return an error code: - git_pathdup_submodule() returns NULL when we fail to find a path. - strbuf_git_path_submodule() propagates the error code to the caller. Modify the callers of these functions to check the error code and fail properly. This ensures we don't attempt to use a bad path that doesn't match the corresponding submodule. Because this change fixes add_submodule_odb() to work even if the submodule is not checked out, update the wording of the submodule log diff format to correctly display that the submodule is "not initialized" instead of "not checked out" Add tests to ensure this change works as expected.

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>

2016-08-30test-lib: drop PID from test-results/*.countLibravatar Jeff King1-2/+2
Each test run generates a "count" file in t/test-results that stores the number of successful, failed, etc tests. If you run "t1234-foo.sh", that file is named as "t/test-results/t1234-foo-$$.count" The addition of the PID there is serving no purpose, and makes analysis of the count files harder. The presence of the PID dates back to 2d84e9f (Modify test-lib.sh to output stats to t/test-results/*, 2008-06-08), but no reasoning is given there. Looking at the current code, we can see that other files we write to test-results (like *.exit and *.out) do _not_ have the PID included. So the presence of the PID does not meaningfully allow one to store the results from multiple runs anyway. Moreover, anybody wishing to read the *.count files to aggregate results has to deal with the presence of multiple files for a given test (and figure out which one is the most recent based on their timestamps!). The only consumer of these files is the aggregate.sh script, which arguably gets this wrong. If a test is run multiple times, its counts will appear multiple times in the total (I say arguably only because the desired semantics aren't documented anywhere, but I have trouble seeing how this behavior could be useful). So let's just drop the PID, which fixes aggregate.sh, and will make new features based around the count files easier to write. Note that since the count-file may already exist (when re-running a test), we also switch the "cat" from appending to truncating. The use of append here was pointless in the first place, as we expected to always write to a unique file. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Since 3b75ee9 ("blame: allow to blame paths freshly added to the index", 2016-07-16) git blame also looks at the index to determine if there is a file that was freshly added to the index. cache_name_pos returns -pos - 1 in case there is no match is found, or if the name matches, but the entry has a stage other than 0. As git blame should work for unmerged files, it uses strcmp to determine whether the name of the returned position matches, in which case the file exists, but is merely unmerged, or if the file actually doesn't exist in the index. If the repository is empty, or if the file would lexicographically be sorted as the last file in the repository, -cache_name_pos - 1 is outside of the length of the active_cache array, causing git blame to segfault. Guard against that, and die() normally to restore the old behaviour.

2016-08-23mingw: ensure temporary file handles are not inherited by child processesLibravatar Ben Wijen1-1/+1
When the index is locked and child processes inherit the handle to said lock and the parent process wants to remove the lock before the child process exits, on Windows there is a problem: it won't work because files cannot be deleted if a process holds a handle on them. The symptom: Rename from 'xxx/.git/index.lock' to 'xxx/.git/index' failed. Should I try again? (y/n) Spawning child processes with bInheritHandles==FALSE would not work because no file handles would be inherited, not even the hStdXxx handles in STARTUPINFO (stdin/stdout/stderr). Opening every file with O_NOINHERIT does not work, either, as e.g. git-upload-pack expects inherited file handles. This leaves us with the only way out: creating temp files with the O_NOINHERIT flag. This flag is Windows-specific, however. For our purposes, it is equivalent to O_CLOEXEC (which does not exist on Windows), so let's just open temporary files with the O_CLOEXEC flag and map that flag to O_NOINHERIT on Windows. As Eric Wong pointed out, we need to be careful to handle the case where the Linux headers used to compile Git support O_CLOEXEC but the Linux kernel used to run Git does not: it returns an EINVAL. This fixes the test that we just introduced to demonstrate the problem.

When "git merge-recursive" works on history with many criss-cross merges in "verbose" mode, the names the command assigns to the virtual merge bases could have overwritten each other by unintended reuse of the same piece of memory. * rs/pull-signed-tag: commit: use FLEX_ARRAY in struct merge_remote_desc merge-recursive: fix verbose output for multiple base trees commit: factor out set_merge_remote_desc() commit: use xstrdup() in get_merge_parent()
2016-08-18t6026-merge-attr: child processes must not inherit index.lock handlesLibravatar Ben Wijen1-0/+13
On Windows, a file cannot be removed unless all file handles to it have been released. Hence it is particularly important to close handles when spawning children (which would probably not even know that they hold on to those handles). The example chosen for this test is a custom merge driver that indeed has no idea that it blocks the deletion of index.lock. The full use case is a daemon that lives on after the merge, with subsequent invocations handing off to the daemon, thereby avoiding hefty start-up costs. We simulate this behavior by simply sleeping one second. Note that the test only fails on Windows, due to the file locking issue. Since we have no way to say "expect failure with MINGW, success otherwise", we simply skip this test on Windows for now.

2016-08-17clone: recursive and reference option triggers submodule alternatesLibravatar Stefan Beller1-0/+43
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.

2016-08-17Merge branch 'js/test-lint-pathname'Libravatar Junio C Hamano1-1/+10
The "t/" hierarchy is prone to get an unusual pathname; "make test" has been taught to make sure they do not contain paths that cannot be checked out on Windows (and the mechanism can be reusable to catch pathnames that are not portable to other platforms as need arises). * js/test-lint-pathname: t/Makefile: ensure that paths are valid on platforms we care
