Libcurl has a CURLOPT_RESOLVE easy option that allows
the result of hostname resolution in the following
format to be passed:
[+]HOST:PORT:ADDRESS[,ADDRESS]
This way, redirects and everything operating against the
HOST+PORT will use the provided ADDRESS(s).
The following format is also allowed to stop using
hostname resolutions that have already been passed:
-HOST:PORT
See https://curl.se/libcurl/c/CURLOPT_RESOLVE.html for
more details.
Let's add a corresponding "http.curloptResolve" config
option that takes advantage of CURLOPT_RESOLVE.
Each value configured for the "http.curloptResolve" key
is passed "as is" to libcurl through CURLOPT_RESOLVE, so
it should be in one of the above 2 formats. This keeps
the implementation simple and makes us consistent with
libcurl's CURLOPT_RESOLVE, and with curl's corresponding
`--resolve` command line option.
The implementation uses CURLOPT_RESOLVE only in
get_active_slot() which is called by all the HTTP
request sending functions.

bdc77d1d68 (Add a function to determine whether a path is owned by the
current user, 2022-03-02) checks for the effective uid of the running
process using geteuid() but didn't account for cases where that user was
root (because git was invoked through sudo or a compatible tool) and the
original uid that repository trusted for its config was no longer known,
therefore failing the following otherwise safe call:
guy@renard ~/Software/uncrustify $ sudo git describe --always --dirty
[sudo] password for guy:
fatal: unsafe repository ('/home/guy/Software/uncrustify' is owned by someone else)
Attempt to detect those cases by using the environment variables that
those tools create to keep track of the original user id, and do the
ownership check using that instead.
This assumes the environment the user is running on after going
privileged can't be tampered with, and also adds code to restrict that
the new behavior only applies if running as root, therefore keeping the
most common case, which runs unprivileged, from changing, but because of
that, it will miss cases where sudo (or an equivalent) was used to change
to another unprivileged user or where the equivalent tool used to raise
privileges didn't track the original id in a sudo compatible way.
Because of compatibility with sudo, the code assumes that uid_t is an
unsigned integer type (which is not required by the standard) but is used
that way in their codebase to generate SUDO_UID. In systems where uid_t
is signed, sudo might be also patched to NOT be unsigned and that might
be able to trigger an edge case and a bug (as described in the code), but
it is considered unlikely to happen and even if it does, the code would
just mostly fail safely, so there was no attempt either to detect it or
prevent it by the code, which is something that might change in the future,
based on expected user feedback.

Before describing how to send patches to the mailing list either with
GitGitGadget or 'git send-email', the MyFirstContribution tutorial
includes a small "Getting Ready to Share" section where the two
different methods are briefly introduced.
Use this section to also describe what a patch series looks like once
submitted, so that readers get an understanding of the end result before
diving into how to accomplish that end result.
Start by copying the "thread overview" section of a recent contribution
from the public-inbox web UI and explaining how each commit is a
separate mail, and point out the cover letter.
Subsequent commits will move the existing description of the purpose of
the cover letter from the 'git send-email' section to this "anatomy"
section.
Also, change the wording in the introductory paragraph to use
"contributions" instead of "patches", since this makes more sense when
talking about GitHub pull requests.

git-p4 is designed to run correctly under python2.7 and python3, but
its functional behavior wrt importing user-entered text differs across
these environments:
Under python2, git-p4 "naively" writes the Perforce bytestream into git
metadata (and does not set an "encoding" header on the commits); this
means that any non-utf-8 byte sequences end up creating invalidly-encoded
commit metadata in git.
Under python3, git-p4 attempts to decode the Perforce bytestream as utf-8
data, and fails badly (with an unhelpful error) when non-utf-8 data is
encountered.
Perforce clients (especially p4v) encourage user entry of changelist
descriptions (and user full names) in OS-local encoding, and store the
resulting bytestream to the server unmodified - such that different
clients can end up creating mutually-unintelligible messages. The most
common inconsistency, in many Perforce environments, is likely to be utf-8
(typical in linux) vs cp-1252 (typical in windows).
Make the changelist-description- and user-fullname-handling code
python-runtime-agnostic, introducing three "strategies" selectable via
config:
- 'passthrough', behaving as previously under python2,
- 'strict', behaving as previously under python3, and
- 'fallback', favoring utf-8 but supporting a secondary encoding when
utf-8 decoding fails, and finally escaping high-range bytes if the
decoding with the secondary encoding also fails.
Keep the python2 default behavior as-is ('legacy' strategy), but switch
the python3 default strategy to 'fallback' with default fallback encoding
'cp1252'.
Also include tests exercising these encoding strategies, documentation for
the new config, and improve the user-facing error messages when decoding
does fail.

In some "simple" centralized workflows, users expect remote tracking
branch names to match local branch names. "git push" pushes to the
remote version/instance of the branch, and "git pull" pulls any changes
to the remote branch (changes made by the same user in another place, or
by other users).
This expectation is supported by the push.default default option "simple"
which refuses a default push for a mismatching tracking branch name, and
by the new branch.autosetupmerge option, "simple", which only sets up
remote tracking for same-name remote branches.
When a new branch has been created by the user and has not yet been
pushed (and push.default is not set to "current"), the user is prompted
with a "The current branch %s has no upstream branch" error, and
instructions on how to push and add tracking.
This error is helpful in that following the advice once per branch
"resolves" the issue for that branch forever, but inconvenient in that
for the "simple" centralized workflow, this is always the right thing to
do, so it would be better to just do it.
Support this workflow with a new config setting, push.autoSetupRemote,
which will cause a default push, when there is no remote tracking branch
configured, to push to the same-name on the remote and --set-upstream.
Also add a hint offering this new option when the "The current branch %s
has no upstream branch" error is encountered, and add corresponding tests.

With "push.default=current" configured, a simple "git push" will push to
the same-name branch on the current branch's branch.<name>.pushRemote, or
remote.pushDefault, or origin. If none of these are defined, the push will
fail with error "fatal: No configured push destination".
The same "default to origin if no config" behavior applies with
"push.default=matching".
Other commands use "origin" as a default when there are multiple options,
but default to the single remote when there is only one - for example,
"git checkout <something>". This "assume the single remote if there is
only one" behavior is more friendly/useful than a defaulting behavior
that only uses the name "origin" no matter what.
Update "git push" to also default to the single remote (and finally fall
back to "origin" as default if there are several), for
"push.default=current" and for other current and future remote-defaulting
push behaviors.
This change also modifies the behavior of ls-remote in a consistent way,
so defaulting not only supplies 'origin', but any single configured remote
also.
Document the change in behavior, correct incorrect assumptions in related
tests, and add test cases reflecting this new single-remote-defaulting
behavior.

With the default push.default option, "simple", beginners are
protected from accidentally pushing to the "wrong" branch in
centralized workflows: if the remote tracking branch they would push
to does not have the same name as the local branch, and they try to do
a "default push", they get an error and explanation with options.
There is a particular centralized workflow where this often happens:
a user branches to a new local topic branch from an existing
remote branch, eg with "checkout -b feature1 origin/master". With
the default branch.autosetupmerge configuration (value "true"), git
will automatically add origin/master as the upstream tracking branch.
When the user pushes with a default "git push", with the intention of
pushing their (new) topic branch to the remote, they get an error, and
(amongst other things) a suggestion to run "git push origin HEAD".
If they follow this suggestion the push succeeds, but on subsequent
default pushes they continue to get an error - so eventually they
figure out to add "-u" to change the tracking branch, or they spelunk
the push.default config doc as proposed and set it to "current", or
some GUI tooling does one or the other of these things for them.
When one of their coworkers later works on the same topic branch,
they don't get any of that "weirdness". They just "git checkout
feature1" and everything works exactly as they expect, with the shared
remote branch set up as remote tracking branch, and push and pull
working out of the box.
The "stable state" for this way of working is that local branches have
the same-name remote tracking branch (origin/feature1 in this
example), and multiple people can work on that remote feature branch
at the same time, trusting "git pull" to merge or rebase as required
for them to be able to push their interim changes to that same feature
branch on that same remote.
(merging from the upstream "master" branch, and merging back to it,
are separate more involved processes in this flow).
There is a problem in this flow/way of working, however, which is that
the first user, when they first branched from origin/master, ended up
with the "wrong" remote tracking branch (different from the stable
state). For a while, before they pushed (and maybe longer, if they
don't use -u/--set-upstream), their "git pull" wasn't getting other
users' changes to the feature branch - it was getting any changes from
the remote "master" branch instead (a completely different class of
changes!)
An experienced git user might say "well yeah, that's what it means to
have the remote tracking branch set to origin/master!" - but the
original user above didn't *ask* to have the remote master branch
added as remote tracking branch - that just happened automatically
when they branched their feature branch. They didn't necessarily even
notice or understand the meaning of the "set up to track 'origin/master'"
message when they created the branch - especially if they are using a
GUI.
Looking at how to fix this, you might think "OK, so disable auto setup
of remote tracking - set branch.autosetupmerge to false" - but that
will inconvenience the *second* user in this story - the one who just
wanted to start working on the topic branch. The first and second
users swap roles at different points in time of course - they should
both have a sane configuration that does the right thing in both
situations.
Make this "branches have the same name locally as on the remote"
workflow less painful / more obvious by introducing a new
branch.autosetupmerge option called "simple", to match the same-name
"push.default" option that makes similar assumptions.
This new option automatically sets up tracking in a *subset* of the
current default situations: when the original ref is a remote tracking
branch *and* has the same branch name on the remote (as the new local
branch name).
Update the error displayed when the 'push.default=simple' configuration
rejects a mismatching-upstream-name default push, to offer this new
branch.autosetupmerge option that will prevent this class of error.
With this new configuration, in the example situation above, the first
user does *not* get origin/master set up as the tracking branch for
the new local branch. If they "git pull" in their new local-only
branch, they get an error explaining there is no upstream branch -
which makes sense and is helpful. If they "git push", they get an
error explaining how to push *and* suggesting they specify
--set-upstream - which is exactly the right thing to do for them.
This new option is likely not appropriate for users intentionally
implementing a "triangular workflow" with a shared upstream tracking
branch, that they "git pull" in and a "private" feature branch that
they push/force-push to just for remote safe-keeping until they are
ready to push up to the shared branch explicitly/separately. Such
users are likely to prefer keeping the current default
merge.autosetupmerge=true behavior, and change their push.default to
"current".
Also extend the existing branch tests with three new cases testing
this option - the obvious matching-name and non-matching-name cases,
and also a non-matching-ref-type case. The matching-name case needs to
temporarily create an independent repo to fetch from, as the general
strategy of using the local repo as the remote in these tests
precludes locally branching with the same name as in the "remote".

The "--since=<time>" option of "git log" limits the commits displayed by
the command by stopping the traversal once it sees a commit whose
timestamp is older than the given time and not digging further into its
parents.
This is OK in a history where a commit always has a newer timestamp than
any of its parents'. Once you see a commit older than the given <time>,
all ancestor commits of it are even older than the time anyway. It
poses, however, a problem when there is a commit with a wrong timestamp
that makes it appear older than its parents. Stopping traversal at the
"incorrectly old" commit will hide its ancestors that are newer than
that wrong commit and are newer than the cut-off time given with the
--since option. --max-age and --after being the synonyms to --since,
they share the same issue.
Add a new "--since-as-filter" option that is a variant of
"--since=<time>". Instead of stopping the traversal to hide an old
enough commit and its all ancestors, exclude commits with an old
timestamp from the output but still keep digging the history.
Without other traversal stopping options, this will force the command in
"git log" family to dig down the history to the root. It may be an
acceptable cost for a small project with short history and many commits
with screwy timestamps.
It is quite unlikely for us to add traversal stopper other than since,
so have this as a --since-as-filter option, rather than a separate
--as-filter, that would be probably more confusing.
