+Subject: [PATCH v2] gitk: Add support of SHA256 repo
+Date: Tue, 17 Jun 2025 07:59:54 +0200
+Message-ID: <20250617055957.9794-1-tiwai@suse.de>
+
+This patch adds a basic support of SHA256 Git repository to Gitk, so
+that Gitk can show and operate on both SHA1 and SHA256 repos
+gracefully.  Since SHA256 has a longer ID length (64 char) than SHA1
+(40 char), many field widths are adjusted to fit with it.
+
+A caveat is that the configuration of auto selection length is shared
+between SHA1 and SHA256 repos.  That is, once when this value is saved
+and read, it's applied to both repo types, which may result in shorter
+selection than the full SHA256 ID.  We may introduce another
+individual config for sha256 (actually I did write in the first
+version), but for simplicity, the common config is used as of writing
+this.
+
+Many lines still refer "sha1" although they may point to both SHA1 and
+SHA256.  They are left untouched for making the changes simpler.
+
+This patch is based on the early work by Rostislav Krasny:
+  https://patchwork.kernel.org/project/git/patch/pull.979.git.1623687519832.gitgitgadget@gmail.com
+I refreshed, revised and extended to the latest state.

+Subject: [PATCH] git-gui: Add support of SHA256 repo
+
+This patch adds the basic support of SHA256 Git repositories.
+The needed changes were mostly about adjusting the fixed ID length of
+SHA1 (40) to be variable depending on the repo type.

+  0001-gitk-Add-support-of-SHA256-repo.patch
+  0002-git-gui-Add-support-of-SHA256-repo.patch
+
+-------------------------------------------------------------------
+Wed Jul  9 10:48:56 UTC 2025 - Marcus Rueckert <mrueckert@suse.de>
+
+- update to 2.50.1 (boo#1245938 boo#1245939 boo#1245942 boo#1245943 
+  boo#1245946 boo#1245947)
+  Security fixes for CVE-2025-27613, CVE-2025-27614,
+  CVE-2025-46334, CVE-2025-46835, CVE-2025-48384, CVE-2025-48385,
+  and CVE-2025-48386
+
+  CVE-2025-27613, Gitk:
+
+  When a user clones an untrusted repository and runs Gitk without
+  additional command arguments, any writable file can be created and
+  truncated. The option "Support per-file encoding" must have been
+  enabled. The operation "Show origin of this line" is affected as
+  well, regardless of the option being enabled or not.
+
+  CVE-2025-27614, Gitk:
+
+  A Git repository can be crafted in such a way that a user who has
+  cloned the repository can be tricked into running any script
+  supplied by the attacker by invoking `gitk filename`, where
+  `filename` has a particular structure.
+
+  CVE-2025-46334, Git GUI (Windows only):
+
+  A malicious repository can ship versions of sh.exe or typical
+  textconv filter programs such as astextplain. On Windows, path
+  lookup can find such executables in the worktree. These programs
+  are invoked when the user selects "Git Bash" or "Browse Files" from
+  the menu.
+
+  CVE-2025-46835, Git GUI:
+
+  When a user clones an untrusted repository and is tricked into
+  editing a file located in a maliciously named directory in the
+  repository, then Git GUI can create and overwrite any writable
+  file.
+
+  CVE-2025-48384, Git:
+
+  When reading a config value, Git strips any trailing carriage
+  return and line feed (CRLF). When writing a config entry, values
+  with a trailing CR are not quoted, causing the CR to be lost when
+  the config is later read.  When initializing a submodule, if the
+  submodule path contains a trailing CR, the altered path is read
+  resulting in the submodule being checked out to an incorrect
+  location. If a symlink exists that points the altered path to the
+  submodule hooks directory, and the submodule contains an executable
+  post-checkout hook, the script may be unintentionally executed
+  after checkout.
+
+  CVE-2025-48385, Git:
+
+  When cloning a repository Git knows to optionally fetch a bundle
+  advertised by the remote server, which allows the server-side to
+  offload parts of the clone to a CDN. The Git client does not
+  perform sufficient validation of the advertised bundles, which
+  allows the remote side to perform protocol injection.
+  This protocol injection can cause the client to write the fetched
+  bundle to a location controlled by the adversary. The fetched
+  content is fully controlled by the server, which can in the worst
+  case lead to arbitrary code execution.
+  CVE-2025-48386, Git:
+
+  The wincred credential helper uses a static buffer (`target`) as a
+  unique key for storing and comparing against internal storage. This
+  credential helper does not properly bounds check the available
+  space remaining in the buffer before appending to it with
+  `wcsncat()`, leading to potential buffer overflows.

+  * Performance improvements
+  * Other improvements, UI changes, options extensions and largely

+
+- update to 2.47.1:
+  * Use after free and double freeing at the end in
+    "git log -L... -p" had been identified and fixed.
+  * "git maintenance start" crashed due to an uninitialized
+    variable reference, which has been corrected.
+  * Fail gracefully instead of crashing when attempting to write
+    the contents of a corrupt in-core index as a tree object.
+  * A "git fetch" from the superproject going down to a submodule
+    used a wrong remote when the default remote names are set
+    differently between them.
+  * The "gitk" project tree has been synchronized again
+
+-------------------------------------------------------------------
+Wed Oct  9 10:34:12 UTC 2024 - Dirk Müller <dmueller@suse.com>
+
+- update to 2.47.0:
+  * https://raw.githubusercontent.com/git/git/master/Documentation/RelNotes/2.47.0.txt
+  * Many Porcelain commands that internally use the merge machinery
+    were taught to consistently honor the diff.algorithm
+    configuration.
+ * A few descriptions in "git show-ref -h" have been clarified.
+ * A 'P' command to "git add -p" that passes the patch hunk to the
+   pager has been added.
+ * "git grep -W" omits blank lines that follow the found function at
+   the end of the file, just like it omits blank lines before the next
+   function.
+ * The value of http.proxy can have "path" at the end for a socks
+   proxy that listens to a unix-domain socket, but we started to
+   discard it when we taught proxy auth code path to use the
+   credential helpers, which has been corrected.
+ * The code paths to compact multiple reftable files have been updated
+   to correctly deal with multiple compaction triggering at the same
+   time.
+ * Support to specify ref backend for submodules has been enhanced.
+ * "git svn" has been taught about svn:global-ignores property
+   recent versions of Subversion has.
+ * The default object hash and ref backend format used to be settable
+   only with explicit command line option to "git init" and
+   environment variables, but now they can be configured in the user's
+   global and system wide configuration.
+ * "git send-email" learned "--translate-aliases" option that reads
+   addresses from the standard input and emits the result of applying
+   aliases on them to the standard output.
+ * 'git for-each-ref' learned a new "--format" atom to find the branch
+   that the history leading to a given commit "%(is-base:<commit>)" is
+   likely based on.
+ * The command line prompt support used to be littered with bash-isms,
+   which has been corrected to work with more shells.
+ * Support for the RUNTIME_PREFIX feature has been added to z/OS port.
+ * "git send-email" learned "--mailmap" option to allow rewriting the
+   recipient addresses.
+ * "git mergetool" learned to use VSCode as a merge backend.
+ * "git pack-redundant" has been marked for removal in Git 3.0.
+ * One-line messages to "die" and other helper functions will get LF
+   added by these helper functions, but many existing messages had an
+   unnecessary LF at the end, which have been corrected.
+ * The "scalar clone" command learned the "--no-tags" option.
+ * The environment GIT_ADVICE has been intentionally kept undocumented
+   to discourage its use by interactive users.  Add documentation to
+   help tool writers.
+ * "git apply --3way" learned to take "--ours" and other options.
+

+Mon Oct  7 12:01:19 UTC 2024 - Antonio Teixeira <antonio.teixeira@suse.com>
+
+- Update to version 2.46.2:
+  * Revert the "git patch-id" change that went into 2.46.1,
+    as it seems to have got a regression reported (I haven't verified,
+    but it is better to keep a known breakage than adding an unintended
+    regression).
+  * In a few corner cases "git diff --exit-code" failed to report
+    "changes" (e.g., renamed without any content change), which has
+    been corrected.
+  * The interpret-trailers command failed to recognise the end of the
+    message when the commit log ends in an incomplete line.
+
+-------------------------------------------------------------------
+Fri Sep 20 08:18:30 UTC 2024 - Dominique Leuenberger <dimstar@opensuse.org>
+
+- Update to version 2.46.1;
+  * "git checkout --ours" (no other arguments) complained that the
+    option is incompatible with branch switching, which is technically
+    correct, but found confusing by some users.  It now says that the
+    user needs to give pathspec to specify what paths to checkout.
+  * It has been documented that we avoid "VAR=VAL shell_func" and why.
+  * "git add -p" by users with diff.suppressBlankEmpty set to true
+    failed to parse the patch that represents an unmodified empty line
+    with an empty line (not a line with a single space on it), which
+    has been corrected.
+  * "git rebase --help" referred to "offset" (the difference between
+    the location a change was taken from and the change gets replaced)
+    incorrectly and called it "fuzz", which has been corrected.
+  * "git notes add -m '' --allow-empty" and friends that take prepared
+    data to create notes should not invoke an editor, but it started
+    doing so since Git 2.42, which has been corrected.
+  * An expensive operation to prepare tracing was done in re-encoding
+    code path even when the tracing was not requested, which has been
+    corrected.
+  * Perforce tests have been updated.
+  * The credential helper to talk to OSX keychain sometimes sent
+    garbage bytes after the username, which has been corrected.
+  * A recent update broke "git ls-remote" used outside a repository,
+    which has been corrected.
+  * "git config --value=foo --fixed-value section.key newvalue" barfed
+    when the existing value in the configuration file used the
+    valueless true syntax, which has been corrected.
+  * "git reflog expire" failed to honor annotated tags when computing
+   reachable commits.
+  * A flakey test and incorrect calls to strtoX() functions have been
+    fixed.
+  * Follow-up on 2.45.1 regression fix.
+  * "git rev-list ... | git diff-tree -p --remerge-diff --stdin" should
+    behave more or less like "git log -p --remerge-diff" but instead it
+    crashed, forgetting to prepare a temporary object store needed.
+  * The patch parser in "git patch-id" has been tightened to avoid
+    getting confused by lines that look like a patch header in the log
+    message.
+  * "git bundle unbundle" outside a repository triggered a BUG()
+    unnecessarily, which has been corrected.
+  * The code forgot to discard unnecessary in-core commit buffer data
+    for commits that "git log --skip=<number>" traversed but omitted
+    from the output, which has been corrected.
+  * "git verify-pack" and "git index-pack" started dying outside a
+    repository, which has been corrected.
+  * A corner case bug in "git stash" was fixed.
