"git push --force-with-lease[=<ref>]" can easily be misused to lose
commits unless the user takes good care of their own "git fetch".
A new option "--force-if-includes" attempts to ensure that what is
being force-pushed was created after examining the commit at the
tip of the remote ref that is about to be force-replaced.
* sk/force-if-includes:
t, doc: update tests, reference for "--force-if-includes"
push: parse and set flag for "--force-if-includes"
push: add reflog check for "--force-if-includes"
|
|
The previous commit added the necessary machinery to implement the
"--force-if-includes" protection, when "--force-with-lease" is used
without giving exact object the remote still ought to have. Surface
the feature by adding a command line option and a configuration
variable to enable it.
- Add a flag: "TRANSPORT_PUSH_FORCE_IF_INCLUDES" to indicate that the
new option was passed from the command line of via configuration
settings; update command line and configuration parsers to set the
new flag accordingly.
- Introduce a new configuration option "push.useForceIfIncludes", which
is equivalent to setting "--force-if-includes" in the command line.
- Update "remote-curl" to recognize and pass this option to "send-pack"
when enabled.
- Update "advise" to catch the reject reason "REJECT_REF_NEEDS_UPDATE",
set when the ref status is "REF_STATUS_REJECT_REMOTE_UPDATED" and
(optionally) print a help message when the push fails.
- The new option is a "no-op" in the following scenarios:
* When used without "--force-with-lease".
* When used with "--force-with-lease", and if the expected commit
on the remote side is specified as an argument.

map_refspec() either returns the passed in ref string or a detached
strbuf. This makes it hard for callers to release the possibly
allocated memory, and set_refspecs() consequently leaks it.
Let map_refspec() append any refspecs directly and release its own
strbufs after use. Rename it to refspec_append_mapped() and don't
return anything to reflect its increased responsibility.
set_refspecs() also leaks its strbufs. Do the same here and directly
call refspec_append() in each if branch instead of holding onto a
detached strbuf, then dispose of the allocated memory after use. We
need to add an else branch for the final call because all the other
conditional branches already add their formatted refspec now.
setup_push_upstream() and setup_push_current() forgot to release their
strbufs as well; plug these leaks, too, while at it.
None of these leaks were likely to impact users, because the number
and sizes of refspecs are usually small and the allocations are only
done once per program run. Clean them up nevertheless, as another
step on the long road towards zero memory leaks.

When the usage for `git push` is shown, it includes the following
lines
--recurse-submodules[=(check|on-demand|no)]
control recursive pushing of submodules
which seem to indicate that the argument for --recurse-submodules is
optional. However, we cannot actually run that optiion without an
argument:
$ git push --recurse-submodules
fatal: recurse-submodules missing parameter
Unset PARSE_OPT_OPTARG so that it is clear that this option requires an
argument. Since the parse-options machinery guarantees that an argument
is present now, assume that `arg` is set in the else of
option_parse_recurse_submodules().

In the codebase, there are many options which use OPTION_CALLBACK in a
plain ol' struct definition. However, we have the OPT_CALLBACK and
OPT_CALLBACK_F macros which are meant to abstract these plain struct
definitions away. These macros are useful as they semantically signal to
developers that these are just normal callback option with nothing fancy
happening.
Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or
OPT_CALLBACK_F where applicable. The heavy lifting was done using the
following (disgusting) shell script:
#!/bin/sh
do_replacement () {
tr '\n' '\r' |
sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\s*0,\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK(\1,\2,\3,\4,\5,\6)/g' |
sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK_F(\1,\2,\3,\4,\5,\6,\7)/g' |
tr '\r' '\n'
}
for f in $(git ls-files \*.c)
do
do_replacement <"$f" >"$f.tmp"
mv "$f.tmp" "$f"
done
The result was manually inspected and then reformatted to match the
style of the surrounding code. Finally, using
`git grep OPTION_CALLBACK \*.c`, leftover results which were not handled
by the script were manually transformed.

Fix an earlier regression to "git push --all" which should have
been forbidden when the target remote repository is set to be a
mirror.
* tg/push-all-in-mirror-forbidden:
push: disallow --all and refspecs when remote.<name>.mirror is set
|
|
Pushes with --all, or refspecs are disallowed when --mirror is given
to 'git push', or when 'remote.<name>.mirror' is set in the config of
the repository, because they can have surprising
effects. 800a4ab399 ("push: check for errors earlier", 2018-05-16)
refactored this code to do that check earlier, so we can explicitly
check for the presence of flags, instead of their sideeffects.
However when 'remote.<name>.mirror' is set in the config, the
TRANSPORT_PUSH_MIRROR flag would only be set after we calling
'do_push()', so the checks would miss it entirely.
This leads to surprises for users [*1*].
Fix this by making sure we set the flag (if appropriate) before
checking for compatibility of the various options.

Change an example push added in b55e677522 ("push: introduce new
push.default mode "simple"", 2012-04-24) to always mean the same thing
whether the current setting happens to be "simple" or not.
This error is only emitted under "simple", but message is explaining
to the user that they can get two sorts of different behaviors by
these two invocations.
Let's use "git push <remote> HEAD" which always means push the current
branch name to that remote, instead of "git push <remote>
<current-branch-name>" which will do that under "simple", but is not
guaranteed to do under "upstream".

The parse-options machinery learned to refrain from enclosing
placeholder string inside a "<bra" and "ket>" pair automatically
without PARSE_OPT_LITERAL_ARGHELP. Existing help text for option
arguments that are not formatted correctly have been identified and
fixed.
* rs/parse-opt-lithelp:
parse-options: automatically infer PARSE_OPT_LITERAL_ARGHELP
shortlog: correct option help for -w
send-pack: specify --force-with-lease argument help explicitly
pack-objects: specify --index-version argument help explicitly
difftool: remove angular brackets from argument help
add, update-index: fix --chmod argument help
push: use PARSE_OPT_LITERAL_ARGHELP instead of unbalanced brackets
|
|
The option help text for the force-with-lease option to "git push"
reads like this:
$ git push -h 2>&1 | grep -e force-with-lease
--force-with-lease[=<refname>:<expect>]
which comes from having N_("refname>:<expect") as the argument help
text in the source code, with an aparent lack of "<" and ">" at both
ends.
It turns out that parse-options machinery takes the whole string and
encloses it inside a pair of "<>", to make it easier for majority
cases that uses a single token placeholder.
The help string was written in a funnily unbalanced way knowing that
the end result would balance out, by somebody who forgot the
presence of PARSE_OPT_LITERAL_ARGHELP, which is the escape hatch
mechanism designed to help such a case. We just should use the
official escape hatch instead.
Because ":<expect>" part can be omitted to ask Git to guess, it may
be more correct to spell it as "<refname>[:<expect>]", but that is
not the focus of this topic.

This is an attempt to resolve an issue I experience with people that are
new to Git -- especially colleagues in a team setting -- where they miss
that their push to a remote location failed because the failure and
success both return a block of white text.
An example is if I push something to a remote repository and then a
colleague attempts to push to the same remote repository and the push
fails because it requires them to pull first, but they don't notice
because a success and failure both return a block of white text. They
then continue about their business, thinking it has been successfully
pushed.
This patch colorizes the errors and hints (in red and yellow,
respectively) so whenever there is a failure when pushing to a remote
repository that fails, it is more noticeable.
[jes: fixed a couple bugs, added the color.{advice,push,transport}
settings, refactored to use want_color_stderr().]

Push options need to be given explicitly, via the command line as "git

which is a multi-valued option, containing push options that are sent

When push options are set in the lower-priority configulation file
(e.g. /etc/gitconfig, or $HOME/.gitconfig), they can be unset later in
the more specific repository config by the empty string.

Teach push the --recurse-submodules=only option. This enables push
to recursively push all unpushed submodules while leaving the
superproject unpushed.
This is a desirable feature in a scenario where updates to the
superproject are handled automatically by some other means, perhaps
a tool like Gerrit code review. In this scenario, a developer could
make a change which spans multiple submodules and then push their
commits for code review. Upon completion of the code review, their
commits can be accepted and applied to their respective submodules
while the code review tool can then automatically update the
superproject to the most recent SHA1 of each submodule. This would
reduce the merge conflicts in the superproject that could occur if
multiple people are contributing to the same submodule.

When the user does the lazy "git push" with no parameters with
push.default set to either "upstream", "simple" or "current",
we internally generated a refspec that has the current branch name
on the source side and used it to push.
However, the branch name (say "test") may be an ambiguous refname in
the context of the source repository---there may be a tag with the
same name, for example. This would trigger an unnecessary error
without any fault on the end-user's side.
Be explicit and give a full refname as the source side to avoid the
ambiguity. The destination side when pushing with the "current"
sent only the name of the branch and forcing the receiving end to
guess, which is the same issue. Be explicit there as well.

Across the transition at around Git version 2.0, the user used to
get a pretty loud warning when running "git push" without setting
push.default configuration variable. We no longer warn, given that
the transition is over long time ago.
* mm/push-default-warning:
push: remove "push.default is unset" warning message
|
|
The warning was important before the 2.0 transition, and remained
important for a while after, so that new users get push.default
explicitly in their configuration and do not experience inconsistent
behavior if they ever used an older version of Git.
The warning has been there since version 1.8.0 (Oct 2012), hence we can
expect the vast majority of current Git users to have been exposed to
it, and most of them have already set push.default explicitly. The
switch from 'matching' to 'simple' was planned for 2.0 (May 2014), but
actually happened only for 2.3 (Feb 2015).
Today, the warning is mostly seen by beginners, who have not set their
push.default configuration (yet). For many of them, the warning is
confusing because it talks about concepts that they have not learned and
asks them a choice that they are not able to make yet. See for example
http://stackoverflow.com/questions/13148066/warning-push-default-is-unset-its-implicit-value-is-changing-in-git-2-0
(1260 votes for the question, 1824 for the answer as of writing)
Remove the warning completely to avoid disturbing beginners. People who
still occasionally use an older version of Git will be exposed to the
warning through this old version.
Eventually, versions of Git without the warning will be deployed enough
and tutorials will not need to advise setting push.default anymore.
