4 daysfast-import: add new --date-format=raw-permissive formatElijah Newren
There are multiple repositories in the wild with random, invalid timezones. Most notably is a commit from rails.git with a timezone of "+051800"[1]. A few searches will find other repos with that same invalid timezone as well. Further, Peff reports that GitHub relaxed their fsck checks in August 2011 to accept any timezone value[2], and there have been multiple reports to filter-repo about fast-import crashing while trying to import their existing repositories since they had timezone values such as "-7349423" and "-43455309"[3]. The existing check on timezone values inside fast-import may prove useful for people who are crafting fast-import input by hand or with a new script. For them, the check may help them avoid accidentally recording invalid dates. (Note that this check is rather simplistic and there are still several forms of invalid dates that fast-import does not check for: dates in the future, timezone values with minutes that are not divisible by 15, and timezone values with minutes that are 60 or greater.) While this simple check may have some value for those users, other users or tools will want to import existing repositories as-is. Provide a --date-format=raw-permissive format that will not error out on these otherwise invalid timezones so that such existing repositories can be imported.

Printing a message directly to stdout could affect TAP processing and is not really needed, as there is a standard way to skip all tests that could be used instead, while printing an equivalent message. While at it; update the message to better reflect that since a85efb5985 (t5608-clone-2gb.sh: turn GIT_TEST_CLONE_2GB into a bool, 2019-11-22), the enabling variable should be a recognized boolean (ex: true, false, 1, 0) and get rid of the prerequisite that used to guard all the tests, since "skip_all" is just much faster and idempotent.

11 dayscheckout: improve error messages for -b with extra argumentRené Scharfe
When we try to create a branch "foo" based on "origin/master" and give git commit -b an extra unsupported argument "bar", it confusingly reports: $ git checkout -b foo origin/master bar fatal: 'bar' is not a commit and a branch 'foo' cannot be created from it $ git checkout --track -b foo origin/master bar fatal: 'bar' is not a commit and a branch 'foo' cannot be created from it That's wrong, because it very well understands that "origin/master" is supposed to be the start point for the new branch and not "bar". Check if we got a commit and show more fitting messages in that case instead: $ git checkout -b foo origin/master bar fatal: Cannot update paths and switch to branch 'foo' at the same time. $ git checkout --track -b foo origin/master bar fatal: '--track' cannot be used with updating paths Original-patch-by: Jeff King <peff@peff.net> Signed-off-by: René Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
11 dayscheckout: add tests for -b and --trackRené Scharfe

In both cases it reports: $ git checkout -b foo origin/master bar fatal: 'bar' is not a commit and a branch 'foo' cannot be created from it The problem is that the start point we gave for the new branch is "origin/master" and "bar" is just some extra argument -- it could even be a valid commit, which would make the message even more confusing. We have more fitting error messages in git commit, but get confused; use the text of the rights ones in the tests.

2020-05-19t4067: make rename detection test output raw diffJonathan Tan
95acf11a3d ("diff: restrict when prefetching occurs", 2020-04-07) taught diff to prefetch blobs in a more limited set of situations. These limited situations include when the output format requires blob data, and when inexact rename detection is needed. There is an existing test case that tests inexact rename detection, but it also uses an output format that requires blob data, resulting in the inexact-rename-detection-only code not being tested. Update this test to use the raw output format, which does not require blob data. Thanks to Derrick Stolee for noticing this lapse in code coverage and for doing the preliminary analysis [1].

2020-05-11bloom: use num_changes not nr for limit detectionDerrick Stolee
As diff_tree_oid() computes a diff, it will terminate early if the total number of changed paths is strictly larger than max_changes. This includes the directories that changed, not just the file paths. However, only the file paths are reflected in the resulting diff queue's "nr" value. Use the "num_changes" from diffopt to check if the diff terminated early. This is incredibly important, as it can result in incorrect filters! For example, the first commit in the Linux kernel repo reports only 471 changes, but since these are nested inside several directories they expand to 513 "real" changes, and in fact the total list of changes is not reported. Thus, the computed filter for this commit is incorrect. Demonstrate the subtle difference by using one fewer file change in the 'get bloom filter for commit with 513 changes' test. Before, this edited 513 files inside "bigDir" which hit this inequality. However, dropping the file count by one demonstrates how the previous inequality was incorrect but the new one is correct.

2020-05-11bloom: de-duplicate directory entriesDerrick Stolee
When computing a changed-path Bloom filter, we need to take the files that changed from the diff computation and extract the parent directories. That way, a directory pathspec such as "Documentation" could match commits that change "Documentation/git.txt". However, the current code does a poor job of this process. The paths are added to a hashmap, but we do not check if an entry already exists with that path. This can create many duplicate entries and cause the filter to have a much larger length than it should. This means that the filter is more sparse than intended, which helps the false positive rate, but wastes a lot of space. Properly use hashmap_get() before hashmap_add(). Also be sure to include a comparison function so these can be matched correctly. This has an effect on a test in t0095-bloom.sh. This makes sense, there are ten changes inside "smallDir" so the total number of paths in the filter should be 11. This would result in 11 * 10 bits required, and with 8 bits per byte, this results in 14 bytes. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-05-11fsck: report non-consecutive duplicate names in treesRené Scharfe
Tree entries are sorted in path order, meaning that directory names get a slash ('/') appended implicitly. Git fsck checks if trees contains consecutive duplicates, but due to that ordering there can be non-consecutive duplicates as well if one of them is a directory and the other one isn't. Such a tree cannot be fully checked out. Find these duplicates by recording candidate file names on a stack and check candidate directory names against that stack to find matches.

When selecting a batch of pack-files to repack in the "git multi-pack-index repack" command, Git should respect the repack.packKeptObjects config option. When false, this option says that the pack-files with an associated ".keep" file should not be repacked. This config value is "false" by default. There are two cases for selecting a batch of objects. The first is the case where the input batch-size is zero, which specifies "repack everything". The second is with a non-zero batch size, which selects pack-files using a greedy selection criteria.

2020-05-09rebase --autosquash: fix a potential segfaultJohannes Schindelin
When rearranging the todo list so that the fixups/squashes are reordered just after the commits they intend to fix up, we use two arrays to maintain that list: `next` and `tail`. The idea is that `next[i]`, if set to a non-negative value, contains the index of the item that should be rearranged just after the `i`th item. To avoid having to walk the entire `next` chain when appending another fixup/squash, we also store the end of the `next` chain in `tail[i]`. The logic we currently use to update these array items is based on the assumption that given a fixup/squash item at index `i`, we just found the index `i2` indicating the first item in that fixup chain. However, as reported by Paul Ganssle, that need not be true: the special form `fixup! <commit-hash>` is allowed to point to _another_ fixup commit in the middle of the fixup chain. Example: * 0192a To fixup * 02f12 fixup! To fixup * 03763 fixup! To fixup * 04ecb fixup! 02f12 Note how the fourth commit targets the second commit, which is already a fixup that targets the first commit. Previously, we would update `next` and `tail` under our assumption that every `fixup!` commit would find the start of the `fixup!`/`squash!` chain. This would lead to a segmentation fault because we would actually end up with a `next[i]` pointing to a `fixup!` but the corresponding `tail[i]` pointing nowhere, which would the lead to a segmentation fault. Let's fix this by _inserting_, rather than _appending_, the item. In other words, if we make a given line successor of another line, we do not simply forget any previously set successor of the latter, but make it a successor of the former. In the above example, at the point when we insert 04ecb just after 02f12, 03763 would already be recorded as a successor of 04ecb, and we now "squeeze in" 04ecb. To complete the idea, we now no longer assume that `next[i]` pointing to a line means that `last[i]` points to a line, too. Instead, we extend the concept of `last` to cover also partial `fixup!`/`squash!` chains, i.e. chains starting in the middle of a larger such chain. In the above example, after processing all lines, `last[0]` (corresponding to 0192a) would point to 03763, which indeed is the end of the overall `fixup!` chain, and `last[1]` (corresponding to 02f12) would point to 04ecb (which is the last `fixup!` targeting 02f12, but it has 03763 as successor, i.e. it is not the end of overall `fixup!` chain).
