| * tests: order arguments to git-rev-list properlyMatthew DeVore2018-10-073-29/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is a common mistake to put positional arguments before flags when invoking git-rev-list. Order the positional arguments last. This patch skips git-rev-list invocations which include the --not flag, since the ordering of flags and positional arguments affects the behavior. This patch also skips invocations of git-rev-list that occur in command substitution in which the exit code is discarded, since fixing those properly will require a more involved cleanup.

| * t9109: don't swallow Git errors upstream of pipesMatthew DeVore2018-10-071-13/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | 'git ... | foo' will mask any errors or crashes in git, so split up such pipes in this file. One testcase uses several separate pipe sequences in a row which are awkward to split up. Wrap the split-up pipe in a function so the awkwardness is not repeated. Also change that testcase's surrounding quotes from double to single to avoid premature string interpolation.

| * tests: don't swallow Git errors upstream of pipesMatthew DeVore2018-10-073-132/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | Some pipes in tests lose the exit code of git processes, which can mask unexpected behavior like crashes. Split these pipes up so that git commands are only at the end of pipes rather than the beginning or middle. The violations fixed in this patch were found in the process of fixing pipe placement in a prior patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using a line-continuation and pipe on the second line, take advantage of the shell's implicit line continuation after a pipe character. So for example, instead of some long line \ | next line use some long line | next line And add a blank line before and after the pipe where it aids readability (it usually does). This better matches the coding style documented in Documentation/CodingGuidelines and used in shell scripts elsewhere in the tree.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The list of Don'ts for test writing has grown large such that it is hard to see at a glance which section an item is in. In other words, if I ignore a little bit of surrounding context, the "don'ts" look like "do's." To make the list more readable, prefix "Don't" in front of every first sentence in the items. Also, the "Keep in mind" list is out of place and awkward, because it was a very short "list" beneath two very long ones, and it seemed easy to miss under the list of "don'ts," and it only had one item. So move this item to the list of "do's" and phrase as "Remember..." Signed-off-by: Matthew DeVore <matvore@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

However after e2ef8d6fa ("cookies: support creation-time attribute for cookies", 2018-08-28) in curl.git (released in curl 7.61.1) that order changed. We document the file format as "Netscape/Mozilla cookie file format (see curl(1))", so any format produced by libcurl should be fine here. Sort the files, to be agnostic to the order of the cookies, and make the test pass with both curl versions > 7.61.1 and earlier curl versions.

Rename it to merge_mode_and_contents() to reflect what it does. merge_content() calls merge_mode_and_contents() to do the main part of its work, but most of this function was about higher level stuff, e.g. printing out conflict messages, updating skip_worktree bits, checking for ability to avoid updating the working tree or for D/F conflicts being in the way, etc. Since there are several handle_*() functions for similar levels of checking and handling in merge-recursive.c (e.g. handle_change_delete(), handle_rename_rename_2to1()), let's rename this function to handle_content_merge().

The previous commit showed that merge_file_one() was prone to be called when merge_file_1() should be, and since it is just a thin wrapper around merge_file_1() anyway and only has one caller left, let's just remove merge_file_one() entirely. (It also turns out that the one remaining caller of merge_file_one() has very broken code that needs to be completely rewritten, but that's the subject of a future patch series; for now, we're just translating it into a merge_file_1() call.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | merge_file_one() is a convenience function taking a bunch of oids and modes, combining each pair into a diff_filespec, and then calling merge_file_1(). When we already start with diff_filespec's, we can just call merge_file_1() directly instead of splitting out the oids and modes for the wrapper to recombine into what we already had.

If the names of the files involved match, it simply uses the branch name. If the names of the files do not match, it uses branchname:filename. Unfortunately, merge_content() previously always called it with one.path = a.path = b.path. Granted, it didn't have other path information available to it for years, but that was corrected by passing rename_conflict_info in commit 3c217c077a86 ("merge-recursive: Provide more info in conflict markers with file renames", 2011-08-11). In that commit, instead of just fixing the bug with the pathnames, it created fake branch names incorporating both the branch name and file name. This "fake branch" workaround was extended further when I pulled that logic out into a special function in commit dac4741554e7 ("merge-recursive: Create function for merging with branchname:file markers", 2011-08-11), and a number of other sites outside of merge_content() have been added which call into that. However, this Rube-Goldberg-esque setup is not merely duplicate code and unnecessary work, it also risked having other callsites invoke it in a way that would result in markers of the form branchname:filename:filename (i.e. with the filename repeated). Fix this whole mess by: - setting one.path, a.path, and b.path appropriately - calling merge_file_1() directly - deleting the merge_file_special_markers() workaround wrapper Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Add a Makefile target to automate this process. This implementation relies on the '-include' and '-xc' arguments to the 'gcc' and 'clang' compilers, which allows us to effectively create the required C compilation unit on-the-fly. This limits the portability of this solution to those systems which have such a compiler. The new 'hdr-check' target can be used to check most header files in the project (for various reasons, the 'compat' and 'xdiff' directories are not included). Also, note that individual header files can be checked directly using the '.hco' extension (read: Hdr-Check Object) like so: $ make config.hco HDR config.h $ Signed-off-by: Ramsay Jones <ramsay@ramsayjones.plus.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

When checking if we can reuse an on-disk delta, the first topic allows base_entry to be NULL when we find an object that's not in the packing list. But the latter topic introduces a call to in_same_island(), which needs to look at base_entry->idx.oid. When these two features are used together, we might try to dereference a NULL base_entry. In practice, this doesn't really happen. We'd generally only use delta islands when packing to disk, since the whole point is to optimize the pack for serving fetches later. And the new delta-reuse code relies on having used reachability bitmaps to determine the set of objects, which we would typically only do when serving an actual fetch. However, it is technically possible to combine these features. And even without doing so, building with "SANITIZE=address,undefined" will cause t5310.46 to complain. Even though that test does not have delta islands enabled, we still take the address of the NULL entry to pass to in_same_island(). That function then promptly returns without dereferencing the value when it sees that islands are not enabled, but it's enough to trigger a sanitizer error. The solution is straight-forward: when both features are used together, we should pass the oid of the found base to in_same_island(). This is tricky to do inside a single "if" statement. And after the merge in f3504ea3dd (Merge branch 'cc/delta-islands', 2018-09-17), that "if" condition is already getting pretty unwieldy. So this patch moves the logic into a helper function, where we can easily use multiple return paths. The result is a bit longer, but the logic should be much easier to follow.

For now, check only if nested aliases work and if looping aliases are detected successfully. The looping aliases check for mixed execution is there but disabled, because it is blocking the test suite for a full minute. As soon as there is a solution for loops using external commands, it should be enabled. Signed-off-by: Tim Schumacher <timschumi@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Resolving further (nested) aliases is prevented by breaking the loop after the first alias was processed. Git then fails with a command-not-found error. Allow resolving nested aliases by not breaking the loop in run_argv() after the first alias was processed. Instead, continue the loop until `handle_alias()` fails, which means that there are no further aliases that can be processed. Prevent looping aliases by storing substituted commands in `cmd_list` and checking if a command has been substituted previously. While we're at it, fix a styling issue just below the added code.

This is necessary in code paths that "fake" shallow commits for the sake of fetch. Specifically, test 351 in t5500-fetch-pack.sh runs git fetch --shallow-exclude one origin with a file-based transfer. When the "remote" has a commit-graph, we do not prevent the commit-graph from being loaded, but then the commits are intended to be dynamically transferred into shallow commits during get_shallow_commits_by_rev_list(). By closing the commit-graph before this call, we prevent this interaction. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
