Merge branch 'jk/http-test-cgipassauth-unavailable-in-older-apache'

We started unconditionally testing with CGIPassAuth directive but
it is unavailable in older Apache that ships with CentOS 7 that has
about a year of shelf-life still left.  The test has conditionally
been disabled when running with an ancient Apache.  This was a fix
for a recent regression caught before the release, so no need to
mention it in the release notes.

* jk/http-test-cgipassauth-unavailable-in-older-apache:
  t/lib-httpd: make CGIPassAuth support conditional

+Git v2.30.8 Release Notes
+=========================
+
+This release addresses the security issues CVE-2023-22490 and
+CVE-2023-23946.
+
+
+Fixes since v2.30.7
+-------------------
+
+ * CVE-2023-22490:
+
+   Using a specially-crafted repository, Git can be tricked into using
+   its local clone optimization even when using a non-local transport.
+   Though Git will abort local clones whose source $GIT_DIR/objects
+   directory contains symbolic links (c.f., CVE-2022-39253), the objects
+   directory itself may still be a symbolic link.
+
+   These two may be combined to include arbitrary files based on known
+   paths on the victim's filesystem within the malicious repository's
+   working copy, allowing for data exfiltration in a similar manner as
+   CVE-2022-39253.
+
+ * CVE-2023-23946:
+
+   By feeding a crafted input to "git apply", a path outside the
+   working tree can be overwritten as the user who is running "git
+   apply".
+
+ * A mismatched type in `attr.c::read_attr_from_index()` which could
+   cause Git to errantly reject attributes on Windows and 32-bit Linux
+   has been corrected.
+
+Credit for finding CVE-2023-22490 goes to yvvdwf, and the fix was
+developed by Taylor Blau, with additional help from others on the
+Git security mailing list.
+
+Credit for finding CVE-2023-23946 goes to Joern Schneeweisz, and the
+fix was developed by Patrick Steinhardt.
+
+
+Johannes Schindelin (1):
+      attr: adjust a mismatched data type
+
+Patrick Steinhardt (1):
+      apply: fix writing behind newly created symbolic links
+
+Taylor Blau (3):
+      t5619: demonstrate clone_local() with ambiguous transport
+      clone: delay picking a transport until after get_repo_path()
+      dir-iterator: prevent top-level symlinks without FOLLOW_SYMLINKS

+Git v2.30.9 Release Notes
+=========================
+
+This release addresses the security issues CVE-2023-25652,
+CVE-2023-25815, and CVE-2023-29007.
+
+
+Fixes since v2.30.8
+-------------------
+
+ * CVE-2023-25652:
+
+   By feeding specially crafted input to `git apply --reject`, a
+   path outside the working tree can be overwritten with partially
+   controlled contents (corresponding to the rejected hunk(s) from
+   the given patch).
+
+ * CVE-2023-25815:
+
+   When Git is compiled with runtime prefix support and runs without
+   translated messages, it still used the gettext machinery to
+   display messages, which subsequently potentially looked for
+   translated messages in unexpected places. This allowed for
+   malicious placement of crafted messages.
+
+ * CVE-2023-29007:
+
+   When renaming or deleting a section from a configuration file,
+   certain malicious configuration values may be misinterpreted as
+   the beginning of a new configuration section, leading to arbitrary
+   configuration injection.
+
+Credit for finding CVE-2023-25652 goes to Ry0taK, and the fix was
+developed by Taylor Blau, Junio C Hamano and Johannes Schindelin,
+with the help of Linus Torvalds.
+
+Credit for finding CVE-2023-25815 goes to Maxime Escourbiac and
+Yassine BENGANA of Michelin, and the fix was developed by Johannes
+Schindelin.
+
+Credit for finding CVE-2023-29007 goes to André Baptista and Vítor Pinho
+of Ethiack, and the fix was developed by Taylor Blau, and Johannes
+Schindelin, with help from Jeff King, and Patrick Steinhardt.

+Git v2.39.3 Release Notes
+=========================
+
+This release merges up the fix that appears in v2.30.9, v2.31.8,
+v2.32.7, v2.33.8, v2.34.8, v2.35.8, v2.36.6, v2.37.7 and v2.38.5 to
+address the security issues CVE-2023-25652, CVE-2023-25815, and
+CVE-2023-29007; see the release notes for these versions for
+details.
+
+This release also merges fixes that have accumulated on the 'master'
+front to prepare for the 2.40 release that are still relevant to
+2.39.x maintenance track.
+
+Fixes since v2.39.2
+-------------------
+
+ * Stop running win+VS build by default.
+
+ * CI updates.  We probably want a clean-up to move the long shell
+   script embedded in yaml file into a separate file, but that can
+   come later.
+
+ * Avoid unnecessary builds in CI, with settings configured in
+   ci-config.
+
+ * Redefining system functions for a few functions did not follow our
+   usual "implement git_foo() and #define foo(args) git_foo(args)"
+   pattern, which has broken build for some folks.
+
+ * Deal with a few deprecation warning from cURL library.
+
+ * Newer regex library macOS stopped enabling GNU-like enhanced BRE,
+   where '\(A\|B\)' works as alternation, unless explicitly asked with
+   the REG_ENHANCED flag.  "git grep" now can be compiled to do so, to
+   retain the old behaviour.
+
+ * When given a pattern that matches an empty string at the end of a
+   line, the code to parse the "git diff" line-ranges fell into an
+   infinite loop, which has been corrected.
+
+ * Fix the sequence to fsync $GIT_DIR/packed-refs file that forgot to
+   flush its output to the disk..
+
+ * "git diff --relative" did not mix well with "git diff --ext-diff",
+   which has been corrected.
+
+ * The logic to see if we are using the "cone" mode by checking the
+   sparsity patterns has been tightened to avoid mistaking a pattern
+   that names a single file as specifying a cone.
+
+ * Doc update for environment variables set when hooks are invoked.
+
+ * Document ORIG_HEAD a bit more.
+
+ * "git ls-tree --format='%(path) %(path)' $tree $path" showed the
+   path three times, which has been corrected.
+
+ * Document that "branch -f <branch>" disables only the safety to
+   avoid recreating an existing branch.
+
+ * Clarify how "checkout -b/-B" and "git branch [-f]" are similar but
+   different in the documentation.
+
+Also contains minor documentation updates and code clean-ups.

  * "scalar" warns but continues when its periodic maintenance

+
+ * "git range-diff" learned --abbrev=<num> option.
+
+ * "git archive HEAD^{tree}" records the paths with the current

+   output.  The command learned the --mtime option to specify an
+   arbitrary timestamp (e.g. --mtime="@0 +0000" for the epoch).
+
+ * The credential subsystem learned that a password may have an
+   explicit expiration.
+
+ * The format.attach configuration variable lacked a way to override a
+   value defined in a lower-priority configuration file (e.g. the
+   system one) by redefining it in a higher-priority configuration
+   file.  Now, setting format.attach to an empty string means show the

+Git v2.41 Release Notes
+=======================
+
+UI, Workflows & Features
+
+ * Allow information carried on the WWW-Authenticate header to be
+   passed to the credential helpers.
+
+ * A new "fetch.hideRefs" option can be used to exclude specified refs
+   from "rev-list --objects --stdin --not --all" traversal for
+   checking object connectivity, most useful when there are many
+   unrelated histories in a single repository.
+
+ * "git push" has been taught to allow deletion of refs with one-level
+   names to help repairing a repository who acquired such a ref by
+   mistake.  In general, we don't encourage use of such a ref, and
+   creation or update to such a ref is rejected as before.
+
+ * Allow "git bisect reset" to check out the original branch when the
+   branch is already checked out in a different worktree linked to the
+   same repository.
+
+ * A few subcommands have been taught to stop users from working on a
+   branch that is being used in another worktree linked to the same
+   repository.
+
+ * "git format-patch" learned to write a log-message only output file
+   for empty commits.
+
+ * "git format-patch" honors the src/dst prefixes set to nonstandard
+   values with configuration variables like "diff.noprefix", causing
+   receiving end of the patch that expects the standard -p1 format to
+   break.  "format-patch" has been taught to ignore end-user configuration
+   and always use the standard prefixes.
+
+   This is a backward compatibility breaking change.
+
+ * Lift the limitation that colored prompts can only be used with
+   PROMPT_COMMAND mode.
+
+ * "git blame --contents=<file> <rev> -- <path>" used to be forbidden,
+   but now it finds the origins of lines starting at <file> contents
+   through the history that leads to <rev>.
+
+ * "git pack-redundant" gave a warning when run, as the command has
+   outlived its usefulness long ago and is nominated for future
+   removal.  Now we escalate to give an error.
+
+ * "git clone" from an empty repository learned to propagate the
+   choice of the hash algorithm from the source repository to the
+   newly created repository.
+
+ * "git mergetool" and "git difftool" learns a new configuration
+   guiDefault to optionally favor configured guitool over non-gui-tool
+   automatically when $DISPLAY is set.
+
+ * "git branch -d origin/master" would say "no such branch", but it is
+   likely a missed "-r" if refs/remotes/origin/master exists.  The
+   command has been taught to give such a hint in its error message.
+
+ * Clean-up of the code path that deals with merge strategy option
+   handling in "git rebase".
+
+ * "git clone --local" stops copying from an original repository that
+   has symbolic links inside its $GIT_DIR; an error message when that
+   happens has been updated.
+
+ * "git branch --format=..." and "git format-patch --format=..."
+   learns "--omit-empty" to hide refs that whose formatting result
+   becomes an empty string from the output.
+
+ * The sendemail-validate validate hook learned to pass the total
+   number of input files and where in the sequence each invocation is
+   via environment variables.
+
+ * When "gc" needs to retain unreachable objects, packing them into
+   cruft packs (instead of exploding them into loose object files) has
+   been offered as a more efficient option for some time.  Now the use
+   of cruft packs has been made the default and no longer considered
+   an experimental feature.
+
+ * The output given by "git blame" that attributes a line to contents
+   taken from the file specified by the "--contents" option shows it
+   differently from a line attributed to the working tree file.
+
+ * "git send-email" learned to give the e-mail headers to the validate
+   hook by passing an extra argument from the command line.
+
+ * The credential subsystem learns to help OAuth framework.
+
+ * The titles of manual pages used to be chomped at an unreasonably
+   short limit, which has been removed.
+
+ * Error messages given when working on an unborn branch that is
+   checked out in another worktree have been improved.
+
+ * The documentation was misleading about the interaction between
+   GIT_DEFAULT_HASH and "git clone", which has been clarified to
+   stress that the variable is to be ignored by the command.
+
+ * "git send-email" learned "--header-cmd=<cmd>" that can inject
+   arbitrary e-mail header lines to the outgoing messages.
+
+ * "git fsck" learned to detect bit-flip breakages in the reachability
+   bitmap files.
+
+ * The "--stdin" option of "git name-rev" has been replaced with
+   the "--annotate-stdin" option more than a year ago.  We stop
+   advertising it in the "git name-rev -h" output.
+
+ * "git push --all" gained an alias "git push --branches".
+
+ * "git fetch" learned the "--porcelain" option that emits what it did
+   in a machine-parseable format.
+
+ * "git --attr-source=<tree> cmd $args" is a new way to have any
+   command to read attributes not from the working tree but from the
+   given tree object.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Code clean-up to clarify directory traversal API.
+
+ * Code clean-up to clarify the rule that "git-compat-util.h" must be
+   the first to be included.
+
+ * More work towards -Wunused.
+
+ * Instead of forcing each command to choose to honor GPG related
+   configuration variables, make the subsystem lazily initialize
+   itself.
+
+ * Remove workaround for ancient versions of DocBook to make it work
+   correctly with groff, which has not been necessary since docbook
+   1.76 from 2010.
+
+ * Code clean-up to include and/or uninclude parse-options.h file as
+   needed.
+
+ * The code path that reports what "git fetch" did to each ref has
+   been cleaned up.
+
+ * Assorted config API updates.
+
+ * A few configuration variables to tell the cURL library that
+   different types of ssl-cert and ssl-key are in use have been added.
+
+ * Split key function and data structure definitions out of cache.h to
+   new header files and adjust the users.
+
+ * "git fetch --all" does not have to download and handle the same
+   bundleURI over and over, which has been corrected.
+
+ * "git sparse-checkout" command learns a debugging aid for the sparse
+   rule definitions.
+
+ * "git write-tree" learns to work better with sparse-index.
+
+ * The on-disk reverse index that allows mapping from the pack offset
+   to the object name for the object stored at the offset has been
+   enabled by default.
+
+ * "git fsck" learned to validate the on-disk pack reverse index files.
+
+ * strtok() and strtok_r() are banned in this codebase.
+
+ * The detect-compilers script to help auto-tweaking the build system
+   had trouble working with compilers whose version number has extra
+   suffixes.  The script has been taught that certain suffixes (like
+   "-win32" in "gcc 10-win32") can be safely stripped as they share
+   the same features and bugs with the version without the suffix.
+
+ * ctype tests have been taught to test EOF, too.
+
+ * The implementation of credential helpers used fgets() over fixed
+   size buffers to read protocol messages, causing the remainder of
+   the folded long line to trigger unexpected behaviour, which has
+   been corrected.
+
+ * The implementation of the default "negotiator", used to find common
+   ancestor over the network for object tranfer, used to be recursive;
+   it was updated to be iterative to conserve stackspace usage.
+
+ * Our custom callout formatter is no longer used in the documentation
+   formatting toolchain, as the upstream default ones give better
+   output these days.
+
+ * The tracing mechanism learned to notice and report when
+   auto-discovered bare repositories are being used, as allowing so
+   without explicitly stating the user intends to do so (with setting
+   GIT_DIR for example) can be used with social engineering as an
+   attack vector.
+
+ * "git diff-files" learned not to expand sparse-index unless needed.
+
+
+Fixes since v2.40
+-----------------
+
+ * "git fsck" learned to check the index files in other worktrees,
+   just like "git gc" honors them as anchoring points.
+   (merge 8d3e7eac52 jk/fsck-indices-in-worktrees later to maint).
+
+ * Fix a segfaulting loop.  The function and its caller may need
+   further clean-up.
+   (merge c5773dc078 ew/commit-reach-clean-up-flags-fix later to maint).
+
+ * "git restore" supports options like "--ours" that are only
+   meaningful during a conflicted merge, but these options are only
+   meaningful when updating the working tree files.  These options are
+   marked to be incompatible when both "--staged" and "--worktree" are
+   in effect.

+WARNING
+-------
+`git pack-redundant` has been deprecated and is scheduled for removal in
+a future version of Git. Because it can only remove entire duplicate
+packs and not individual duplicate objects, it is generally not a useful
+tool for reducing repository size. You are better off using `git gc` to
+do so, which will put objects into a new pack, removing duplicates.
+
+Running `pack-redundant` without the `--i-still-use-this` flag will fail
+in this release. If you believe you have a use case for which
+`pack-redundant` is better suited and oppose this removal, please
+contact the Git mailing list at git@vger.kernel.org. More information

+`histogram` for .c files, and so on without having to pass in the algorithm
+through the command line each time.
+
+First, in `.gitattributes`, assign the `diff` attribute for paths.
+

+------------------------
+
+Then, define a "diff.<name>.algorithm" configuration to specify the diff
+algorithm, choosing from `myers`, `patience`, `minimal`, or `histogram`.
+

+[diff "<name>"]
+  algorithm = histogram

+
+This diff algorithm applies to user facing diff output like git-diff(1),
+git-show(1) and is used for the `--stat` output as well. The merge machinery
+will not use the diff algorithm set through this method.
+
+NOTE: If `diff.<name>.command` is defined for path with the

+It takes these command line arguments. They are,
+1. the name of the file which holds the contents of the email to be sent.
+2. The name of the file which holds the SMTP headers of the email.
+
+The SMTP headers are passed in the exact same way as they are passed to the

+MTA, is the contents of $2 followed by the contents of $1.
+
+An example of a few common headers is shown below. Take notice of the

+
+These variables may for instance be used to validate patch series.
+
+The sample `sendemail-validate` hook that comes with Git checks that all sent

+repository default branch without conflicts. Some placeholders are left for
+additional validation steps to be performed after all patches of a given series
