2019-09-28user-manual.txt: render ASCII art correctly under AsciidoctorMartin Ågren
This commit is similar to 379805051d ("Documentation: render revisions correctly under Asciidoctor", 2018-05-06) and is a no-op with AsciiDoc. When creating a literal block from an indented block without any sort of delimiters, Asciidoctor strips off all leading whitespace, resulting in a misrendered ASCII drawing. Use an explicit literal block to indicate to Asciidoctor that we want to keep the leading whitespace. Drop the common indentation for all lines to make this a no-op with AsciiDoc.

2019-09-28asciidoctor-extensions.rb: handle "book" doctype in linkgitMartin Ågren
user-manual.txt is the only file we process using the "book" doctype. When we use AsciiDoc, user-manual.conf ensures that the linkgit macro expands into something like <ulink url="git-foo.html">git-foo(1)</ulink> in user-manual.xml, which we then process into a clickable link, both in user-manual.html and user-manual.pdf. With Asciidoctor, user-manual.conf is ignored (this is expected) and our Asciidoctor-specific implementation of linkgit kicks in: <citerefentry> <refentrytitle>git-foo</refentrytitle><manvolnum>1</manvolnum> </citerefentry> This eventually renders as "git-foo(1)", which is not bad, but it doesn't turn into a link. Teach our Asciidoctor-specific implementation of the linkgit macro that if the doctype is "book", we should emit <ulink .../> just like we do with AsciiDoc. While we're doing this, future-proof by supporting a "prefix". The implementation in user-manual.conf doesn't support this, and we don't need this for now because user-manual.txt is the only file we process this way (and it's immediately in Documentation/).

2019-09-28user-manual.txt: change header notationMartin Ågren
When AsciiDoc processes user-manual.txt, it generates a book containing chapters containing sections. So for example, we have chapter 6, "Advanced branch management", which contains four relatively short sections, 6.1-6.4. Asciidoctor generates a book containing *parts* containing *chapters* instead. So part 6, "Advanced branch management" contains four short chapters, 1-4. This looks a bit odd. To make AsciiDoc (8.6.10) and Asciidoctor (1.5.5) handle these the same, change from indicating chapters like so: [[foobar]] Foobar ====== to doing it like so: [[foobar]] == Foobar Same thing for sections (line of dashes to ===), subsections (line of tildes to ====) and subsubsections (line of carets to =====). Mark the appendices with "[appendix]", which both AsciiDoc and Asciidoctor understand. This means we need to drop the "Appendix X: " from their titles, or those "Appendix X: " would be included literally in the name of the appendix. This commit is a no-op for AsciiDoc: The generated user-manual.xml is identical before and after this patch. Asciidoctor now creates the same chapter-section-subsection structure as AsciiDoc. Changing the book title at the start of the document to similarly use "=" instead of a line of equal signs makes no difference with any of the engines, but let's do that change anyway for consistency.

2019-09-17clean: avoid removing untracked files in a nested git repositoryElijah Newren
Users expect files in a nested git repository to be left alone unless sufficiently forced (with two -f's). Unfortunately, in certain circumstances, git would delete both tracked (and possibly dirty) files and untracked files within a nested repository. To explain how this happens, let's contrast a couple cases. First, take the following example setup (which assumes we are already within a git repo): git init nested cd nested >tracked git add tracked git commit -m init >untracked cd .. In this setup, everything works as expected; running 'git clean -fd' will result in fill_directory() returning the following paths: nested/ nested/tracked nested/untracked and then correct_untracked_entries() would notice this can be compressed to nested/ and then since "nested/" is a directory, we would call remove_dirs("nested/", ...), which would check is_nonbare_repository_dir() and then decide to skip it. However, if someone also creates an ignored file: >nested/ignored then running 'git clean -fd' would result in fill_directory() returning the same paths: nested/ nested/tracked nested/untracked but correct_untracked_entries() will notice that we had ignored entries under nested/ and thus simplify this list to nested/tracked nested/untracked Since these are not directories, we do not call remove_dirs() which was the only place that had the is_nonbare_repository_dir() safety check -- resulting in us deleting both the untracked file and the tracked (and possibly dirty) file. One possible fix for this issue would be walking the parent directories of each path and checking if they represent nonbare repositories, but that would be wasteful. Even if we added caching of some sort, it's still a waste because we should have been able to check that "nested/" represented a nonbare repository before even descending into it in the first place. Add a DIR_SKIP_NESTED_GIT flag to dir_struct.flags and use it to prevent fill_directory() and friends from descending into nested git repos. With this change, we also modify two regression tests added in commit 91479b9c72f1 ("t7300: add tests to document behavior of clean and nested git", 2015-06-15). That commit, nor its series, nor the six previous iterations of that series on the mailing list discussed why those tests coded the expectation they did. In fact, it appears their purpose was simply to test _existing_ behavior to make sure that the performance changes didn't change the behavior. However, these two tests directly contradicted the manpage's claims that two -f's were required to delete files/directories under a nested git repository. While one could argue that the user gave an explicit path which matched files/directories that were within a nested repository, there's a slippery slope that becomes very difficult for users to understand once you go down that route (e.g. what if they specified "git clean -f -d '*.c'"?) It would also be hard to explain what the exact behavior was; avoid such problems by making it really simple. Also, clean up some grammar errors describing this functionality in the git-clean manpage. Finally, there are still a couple bugs with -ffd not cleaning out enough (e.g. missing the nested .git) and with -ffdX possibly cleaning out the wrong files (paying attention to outer .gitignore instead of inner). This patch does not address these cases at all (and does not change the behavior relative to those flags), it only fixes the handling when given a single -f. See https://public-inbox.org/git/20190905212043.GC32087@szeder.dev/ for more discussion of the -ffd[X?] bugs.

2019-09-17clean: disambiguate the definition of -dElijah Newren
The -d flag pre-dated git-clean's ability to have paths specified. As such, the default for git-clean was to only remove untracked files in the current directory, and -d existed to allow it to recurse into subdirectories. The interaction of paths and the -d option appears to not have been carefully considered, as evidenced by numerous bugs and a dearth of tests covering such pairings in the testsuite. The definition turns out to be important, so let's look at some of the various ways one could interpret the -d option: A) Without -d, only look in subdirectories which contain tracked files under them; with -d, also look in subdirectories which are untracked for files to clean. B) Without specified paths from the user for us to delete, we need to have some kind of default, so...without -d, only look in subdirectories which contain tracked files under them; with -d, also look in subdirectories which are untracked for files to clean. The important distinction here is that choice B says that the presence or absence of '-d' is irrelevant if paths are specified. The logic behind option B is that if a user explicitly asked us to clean a specified pathspec, then we should clean anything that matches that pathspec. Some examples may clarify. Should git clean -f untracked_dir/file remove untracked_dir/file or not? It seems crazy not to, but a strict reading of option A says it shouldn't be removed. How about git clean -f untracked_dir/file1 tracked_dir/file2 or git clean -f untracked_dir_1/file1 untracked_dir_2/file2 ? Should it remove either or both of these files? Should it require multiple runs to remove both the files listed? (If this sounds like a crazy question to even ask, see the commit message of "t7300: Add some testcases showing failure to clean specified pathspecs" added earlier in this patch series.) What if -ffd were used instead of -f -- should that allow these to be removed? Should it take multiple invocations with -ffd? What if a glob (such as '*tracked*') were used instead of spelling out the directory names? What if the filenames involved globs, such as git clean -f '*.o' or git clean -f '*/*.o' ? The current documentation actually suggests a definition that is slightly different than choice A, and the implementation prior to this series provided something radically different than either choices A or B. (The implementation, though, was clearly just buggy). There may be other choices as well. However, for almost any given choice of definition for -d that I can think of, some of the examples above will appear buggy to the user. The only case that doesn't have negative surprises is choice B: treat a user-specified path as a request to clean all untracked files which match that path specification, including recursing into any untracked directories. Change the documentation and basic implementation to use this definition. There were two regression tests that indirectly depended on the current implementation, but neither was about subdirectory handling. These two tests were introduced in commit 5b7570cfb41c ("git-clean: add tests for relative path", 2008-03-07) which was solely created to add coverage for the changes in commit fb328947c8e ("git-clean: correct printing relative path", 2008-03-07). Both tests specified a directory that happened to have an untracked subdirectory, but both were only checking that the resulting printout of a file that was removed was shown with a relative path. Update these tests appropriately. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-09-16doc-diff: replace --cut-header-footer with --cut-footerMartin Ågren
After the previous commit, AsciiDoc and Asciidoctor render the manpage headers identically, so we no longer need the "cut the header" part of our `--cut-header-footer` option. We do still need the "cut the footer" part, though. The previous commits improved the rendering of the footer in Asciidoctor by quite a bit, but the two programs still disagree on how to format the date in the footer: 01/01/1970 vs 1970-01-01. We could keep using `--cut-header-footer`, but it would be nice if we had a slightly smaller hammer `--cut-footer` that would be less likely to hide regressions. Rather than simply adding such an option, let's also drop `--cut-header-footer`, i.e., rework it to lose the "header" part of its name and functionality. `--cut-header-footer` is just a developer tool and it probably has no more than a handful of users, so we can afford to be aggressive.

2019-09-16asciidoctor-extensions: provide `<refmiscinfo/>`Martin Ågren
As can be seen from the previous commit, there are three attributes that we provide to AsciiDoc through asciidoc.conf. Asciidoctor ignores that file. After that patch, newer versions of Asciidoctor pick up the `manmanual` and `mansource` attributes as we invoke `asciidoctor`, but they don't pick up `manversion`. ([1] says: "Not used by Asciidoctor.") Older versions (<1.5.7) don't handle these attributes at all. As a result, we are missing one or three `<refmiscinfo/>` tags in each xml-file produced when we build with Asciidoctor. Because of this, xmlto doesn't include the Git version number in the rendered manpages. And in particular, with versions <1.5.7, the manpage footers instead contain the fairly ugly "[FIXME: source]". That Asciidoctor ignores asciidoc.conf is nothing new. This is why we implement the `linkgit:` macro in asciidoc.conf *and* in asciidoctor-extensions.rb. Follow suit and provide these tags in asciidoctor-extensions.rb, using a "postprocessor" extension where we just search and replace in the XML, treated as text. We may consider a few alternatives: * Inject these lines into the xml-files from the *Makefile*, e.g., using `sed`. That would reduce repetition, but it feels wrong to impose another step and another risk on the AsciiDoc-processing only to benefit the Asciidoctor-one. * I tried providing a "docinfo processor" to inject these tags, but could not figure out how to "merge" the two <refmeta/> sections that resulted. To avoid xmlto barfing on the result, I needed to use `xmlto --skip-validation ...`, which seems unfortunate. Let's instead inject the missing tags using a postprocessor. We'll make it fairly obvious that we aim to inject the exact same three lines of `<refmiscinfo/>` that asciidoc.conf provides. We inject them in *post*-processing so we need to do the variable expansion ourselves. We do introduce the bug that asciidoc.conf already has in that we won't do any escaping, e.g., of funky versions like "some v <2.25, >2.20". The postprocessor we add here works on the XML as raw text and doesn't really use the full potential of XML to do a more structured injection. This is actually precisely what the Asciidoctor User Manual does in its postprocessor example [2]. I looked into two other approaches: 1. The nokogiri library is apparently the "modern" way of doing XML in ruby. I got it working fairly easily: require 'nokogiri' doc = Nokogiri::XML(output) doc.search("refmeta").each { |n| n.add_child(new_tags) } output = doc.to_xml However, this adds another dependency (e.g., the "ruby-nokogiri" package on Ubuntu). Using Asciidoctor is not our default, but it will probably need to become so soon. Let's avoid adding a dependency just so that we can say "search...add_child" rather than "sub(regex...)". 2. The older REXML is apparently always(?) bundled with ruby, but I couldn't even parse the original document: require 'rexml/document' doc = REXML::Document.new(output) ... The error was "no implicit conversion of nil into String" and I stopped there. I don't think it's unlikely that doing a plain old search-and-replace will work just as fine or better compared to parsing XML and worrying about libraries and library versions.

2019-09-16Doc/Makefile: give mansource/-version/-manual attributesMartin Ågren
Rather than hardcoding "Git Manual" and "Git" as the manual and source in asciidoc.conf, provide them as attributes `manmanual` and `mansource`. Rename the `git_version` attribute to `manversion`. These new attribute names are not arbitrary, see, e.g., [1]. For AsciiDoc (8.6.10) and Asciidoctor <1.5.7, this is a no-op. Starting with Asciidoctor 1.5.7, `manmanual` and `mansource` actually end up in the xml-files and eventually in the rendered manpages. In particular, the manpage headers now render just as with AsciiDoc. No versions of Asciidoctor pick up the `manversion` [2], and older versions don't pick up any of these attributes. -- We'll fix that with a bit of a hack in the next commit.

2019-09-16git-submodule.txt: fix AsciiDoc formatting errorDenton Liu
In b57e8119e6 (submodule: teach set-branch subcommand, 2019-02-08), the `set-branch` subcommand was added for submodules. When the documentation was written, the syntax for a "index term" in AsciiDoc was accidentally used. This caused the documentation to be rendered as set-branch -d|--default)|(-b|--branch <branch> [--] <path> instead of set-branch ((-d|--default)|(-b|--branch <branch>)) [--] <path> In addition to this, the original documentation was possibly confusing as it made it seem as if the `-b` option didn't accept a `<branch>` argument. Break `--default` and `--branch` into their own separate invocations to make it obvious that these options are mutually exclusive. Also, this removes the surrounding parentheses so that the "index term" syntax is not triggered. Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-09-16Documentation: fix build with Asciidoctor 2brian m. carlson
Our documentation toolchain has traditionally been built around DocBook 4.5. This version of DocBook is the last DTD-based version of DocBook. In 2009, DocBook 5 was introduced using namespaces and its syntax is expressed in RELAX NG, which is more expressive and allows a wider variety of syntax forms. Asciidoctor, one of the alternatives for building our documentation, moved support for DocBook 4.5 out of core in its recent 2.0 release and now only supports DocBook 5 in the main release. The DocBoook 4.5 converter is still available as a separate component, but this is not available in most distro packages. This would not be a problem but for the fact that we use xmlto, which is still stuck in the DocBook 4.5 era. xmlto performs DTD validation as part of the build process. This is not problematic for DocBook 4.5, which has a valid DTD, but it clearly cannot work for DocBook 5, since no DTD can adequately express its full syntax. In addition, even if xmlto did support RELAX NG validation, that wouldn't be sufficient because it uses the libxml2-based xmllint to do so, which has known problems with validating interleaves in RELAX NG. Fortunately, there's an easy way forward: ask Asciidoctor to use its DocBook 5 backend and tell xmlto to skip validation. Asciidoctor has supported DocBook 5 since v0.1.4 in 2013 and xmlto has supported skipping validation for probably longer than that. We also need to teach xmlto how to use the namespaced DocBook XSLT stylesheets instead of the non-namespaced ones it usually uses. Normally these stylesheets are interchangeable, but the non-namespaced ones have a bug that causes them not to strip whitespace automatically from certain elements when namespaces are in use. This results in additional whitespace at the beginning of list elements, which is jarring and unsightly. We can do this by passing a custom stylesheet with the -x option that simply imports the namespaced stylesheets via a URL. Any system with support for XML catalogs will automatically look this URL up and reference a local copy instead without us having to know where this local copy is located. We know that anyone using xmlto will already have catalogs set up properly since the DocBook 4.5 DTD used during validation is also looked up via catalogs. All major Linux distributions distribute the necessary stylesheets and have built-in catalog support, and Homebrew does as well, albeit with a requirement to set an environment variable to enable catalog support. On the off chance that someone lacks support for catalogs, it is possible for xmlto (via xmllint) to download the stylesheets from the URLs in question, although this will likely perform poorly enough to attract attention. People still have the option of using the prebuilt documentation that we ship, so happily this should not be an impediment. Finally, we need to filter out some messages from other stylesheets that occur when invoking dblatex in the CI job. This tool strips namespaces much like the unnamespaced DocBook stylesheets and prints similar messages. If we permit these messages to be printed to standard error, our documentation CI job will fail because we check standard error for unexpected output. Due to dblatex's reliance on Python 2, we may need to revisit its use in the future, in which case this problem may go away, but this can be delayed until a future patch. The final message we filter is due to libxslt on modern Debian and Ubuntu. The patch which they use to implement reproducible ID generation also prints messages about the ID generation. While this doesn't affect our current CI images since they use Ubuntu 16.04 which lacks this patch, if we upgrade to Ubuntu 18.04 or a modern Debian, these messages will appear and, like the above messages, cause a CI failure.

2019-09-09gitweb.conf.txt: switch pluses to backticks to help AsciidoctorMartin Ågren
This paragraph uses a lot of +pluses+ to render text as monospace. That works fine with AsciiDoc (8.6.10), and almost fine with Asciidoctor (1.5.5), which renders the third of these literally ("+$projname+"). The reason seems to be that Asciidoctor trips on the lone plus a bit earlier, even though it is escaped. Switch +$projname+ to `$projname`, and change the next, similar instance too (+$projname/+), because otherwise, we'd trip on /that one/ instead. If we would stop there, we would now start falling over on the escaped plus ('\+') mentioned earlier, rendering /it/ literally. So change that too... In other words, unescape the lone '+' and change all the pluses that follow it to backticks. AsciiDoc renders this paragraph identically before and after this commit, and Asciidoctor now renders this the same as AsciiDoc. I did try to switch the whole paragraph to using backticks rather than pluses. That worked great with Asciidoctor, but confused AsciiDoc... Let's go with this rather surgical change instead.

2019-09-09git-merge-index.txt: wrap shell listing in "----"Martin Ågren
The example output of `git merge-index` has been enriched by a second "column" of helpful comments. When Asciidoctor renders this, the cells in that second column aren't aligned. Fix this by marking the example shell session as a code listing by wrapping it in "----". Also drop some of the horizontal space between the two columns so that we fit into 80 columns. This changes the rendering with both AsciiDoc and Asciidoctor. They now render this identically, nicely aligned, and within 80 columns.

2019-09-09git-receive-pack.txt: wrap shell [script] listing in "----"Martin Ågren
The indented lines in the example shell script listing are indented differently by AsciiDoc and Asciidoctor. Fix this by marking the example shell script as a code listing by wrapping it in "----". Because this gives us some extra indentation, we can remove the one that we have been carrying explicitly. That is, drop the first tab of indentation on each line. For consistency, make the same change to the short example shell session further down. With AsciiDoc, this results in identical rendering before and after this commit. Asciidoctor now renders this the same as AsciiDoc does. Signed-off-by: Martin Ågren <martin.agren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The second "column" in the output of `git ls-remote` is typeset differently by AsciiDoc and Asciidoctor, similar to various examples touched by the last few commits.

The indented lines in these example config-file listings are indented differently by AsciiDoc and Asciidoctor. Fix this by marking the example config-files as code listings by wrapping them in "----". Because this gives us some extra indentation, we can remove the one that we have been carrying explicitly. That is, drop the first tab of indentation on each line. With AsciiDoc, this results in identical rendering before and after this commit. Asciidoctor now renders this the same as AsciiDoc does. git-config.txt pretty consistently uses twelve dashes rather than the minimum four to spell "----".

2019-09-09git-merge-base.txt: render indentations correctly under AsciidoctorMartin Ågren
There are several graphs in this document. For most of them, we use a single leading tab to indent the whole graph, and then we use spaces (possibly eight or more) to align things within the graph. In the larger graph, we use a different strategy: We use 1-N tabs and just a small number of spaces (<8). This is how we usually prefer to do our indenting, but Asciidoctor ends up rendering this differently from AsciiDoc. Same thing for the if-then-fi examples where the conditional code is indented by two tabs, which renders differently under AsciiDoc and Asciidoctor. Similar to 379805051d ("Documentation: render revisions correctly under Asciidoctor", 2018-05-06), use an explicit literal block to indicate that we want to keep the leading whitespace in the tables. Change not just the ones that render differently, but all of them for consistency. Because this gives us some extra indentation, we can remove the one that we have been carrying explicitly. That is, drop the first tab of indentation on each line. With AsciiDoc, this results in identical rendering before and after this commit, both for git-merge-base.1 and git-merge-base.html. A less intrusive change would be to replace tabs 2-N on each line with eight spaces. But let's follow the example set by 379805051d, so that we can use our preferred way of indenting.

2019-09-09Documentation: wrap blocks with "--"Martin Ågren
The documentation for each of these options contains a list. After the list, AsciiDoc interprets the continuation as a continuation of the *list*, not as a continution of the larger block. As a result, we get too much indentation. Wrap the entire blocks in "--" to fix this. With Asciidoctor, this commit is a no-op, and the two programs now render these identically. These two files share the same problem and indeed, they both document `--untracked-files` in quite similar ways. I haven't checked to what extent that is intentional or warranted, and to what extent they have simply drifted apart. I consider such an investigation and possible cleanup as out of scope for this commit and this patch series.

2019-09-05treewide: rename 'exclude' methods to 'pattern'Derrick Stolee
The first consumer of pattern-matching filenames was the .gitignore feature. In that context, storing a list of patterns as a 'struct exclude_list' makes sense. However, the sparse-checkout feature then adopted these structures and methods, but with the opposite meaning: these patterns match the files that should be included! It would be clearer to rename this entire library as a "pattern matching" library, and the callers apply exclusion/inclusion logic accordingly based on their needs. This commit renames several methods defined in dir.h to make more sense with the renamed 'struct exclude_list' to 'struct pattern_list' and 'struct exclude' to 'struct path_pattern': * last_exclude_matching() -> last_matching_pattern() * parse_exclude() -> parse_path_pattern() In addition, the word 'exclude' was replaced with 'pattern' in the methods below: * add_exclude_list() * add_excludes_from_file_to_list() * add_excludes_from_file() * add_excludes_from_blob_to_list() * add_exclude() * clear_exclude_list() A few methods with the word "exclude" remain. These will be handled seperately. In particular, the method "is_excluded()" is concretely about the .gitignore file relative to a specific directory. This is the important boundary between library and consumer: is_excluded() cares about .gitignore, but is_excluded() calls last_matching_pattern() to make that decision.

2019-09-05Recommend git-filter-repo instead of git-filter-branchElijah Newren
filter-branch suffers from a deluge of disguised dangers that disfigure history rewrites (i.e. deviate from the deliberate changes). Many of these problems are unobtrusive and can easily go undiscovered until the new repository is in use. This can result in problems ranging from an even messier history than what led folks to filter-branch in the first place, to data loss or corruption. These issues cannot be backward compatibly fixed, so add a warning to both filter-branch and its manpage recommending that another tool (such as filter-repo) be used instead. Also, update other manpages that referenced filter-branch. Several of these needed updates even if we could continue recommending filter-branch, either due to implying that something was unique to filter-branch when it applied more generally to all history rewriting tools (e.g. BFG, reposurgeon, fast-import, filter-repo), or because something about filter-branch was used as an example despite other more commonly known examples now existing. Reword these sections to fix these issues and to avoid recommending filter-branch. Finally, remove the section explaining BFG Repo Cleaner as an alternative to filter-branch. I feel somewhat bad about this, especially since I feel like I learned so much from BFG that I put to good use in filter-repo (which is much more than I can say for filter-branch), but keeping that section presented a few problems: * In order to recommend that people quit using filter-branch, we need to provide them a recomendation for something else to use that can handle all the same types of rewrites. To my knowledge, filter-repo is the only such tool. So it needs to be mentioned. * I don't want to give conflicting recommendations to users * If we recommend two tools, we shouldn't expect users to learn both and pick which one to use; we should explain which problems one can solve that the other can't or when one is much faster than the other. * BFG and filter-repo have similar performance * All filtering types that BFG can do, filter-repo can also do. In fact, filter-repo comes with a reimplementation of BFG named bfg-ish which provides the same user-interface as BFG but with several bugfixes and new features that are hard to implement in BFG due to its technical underpinnings. While I could still mention both tools, it seems like I would need to provide some kind of comparison and I would ultimately just say that filter-repo can do everything BFG can, so ultimately it seems that it is just better to remove that section altogether.

2019-09-03fetch: add fetch.writeCommitGraph config settingDerrick Stolee
The commit-graph feature is now on by default, and is being written during 'git gc' by default. Typically, Git only writes a commit-graph when a 'git gc --auto' command passes the gc.auto setting to actualy do work. This means that a commit-graph will typically fall behind the commits that are being used every day. To stay updated with the latest commits, add a step to 'git fetch' to write a commit-graph after fetching new objects. The fetch.writeCommitGraph config setting enables writing a split commit-graph, so on average the cost of writing this file is very small. Occasionally, the commit-graph chain will collapse to a single level, and this could be slow for very large repos. For additional use, adjust the default to be true when feature.experimental is enabled. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-08-27rebase: teach rebase --keep-baseDenton Liu
A common scenario is if a user is working on a topic branch and they wish to make some changes to intermediate commits or autosquash, they would run something such as git rebase -i --onto master... master in order to preserve the merge base. This is useful when contributing a patch series to the Git mailing list, one often starts on top of the current 'master'. While developing the patches, 'master' is also developed further and it is sometimes not the best idea to keep rebasing on top of 'master', but to keep the base commit as-is. In addition to this, a user wishing to test individual commits in a topic branch without changing anything may run git rebase -x ./test.sh master... master Since rebasing onto the merge base of the branch and the upstream is such a common case, introduce the --keep-base option as a shortcut. This allows us to rewrite the above as git rebase -i --keep-base master and git rebase -x ./test.sh --keep-base master respectively. Add tests to ensure --keep-base works correctly in the normal case and fails when there are multiple merge bases, both in regular and interactive mode. Also, test to make sure conflicting options cause rebase to fail. While we're adding test cases, add a missing set_fake_editor call to 'rebase -i --onto master...side'. While we're documenting the --keep-base option, change an instance of "merge-base" to "merge base", which is the consistent spelling.

2019-08-21userdiff: add a builtin pattern for dts filesStephen Boyd
The Linux kernel receives many patches to the devicetree files each release. The hunk header for those patches typically show nothing, making it difficult to figure out what node is being modified without applying the patch or opening the file and seeking to the context. Let's add a builtin 'dts' pattern to git so that users can get better diff output on dts files when they use the diff=dts driver. The regex has been constructed based on the spec at devicetree.org[1] and with some help from Johannes Sixt.
