2021-08-25advice: remove read uses of most global `advice_` variablesLibravatar Ben Boeckel1-6/+6
In c4a09cc9ccb (Merge branch 'hw/advise-ng', 2020-03-25), a new API for accessing advice variables was introduced and deprecated `advice_config` in favor of a new array, `advice_setting`. This patch ports all but two uses which read the status of the global `advice_` variables over to the new `advice_enabled` API. We'll deal with advice_add_embedded_repo and advice_graft_file_deprecated separately.

2021-06-02push: remove redundant checkLibravatar Felipe Contreras1-2/+1
If fetch_remote is NULL (i.e. the branch remote is invalid), then it can't possibly be same as remote, which can't be NULL. The check is redundant, and so is the extra variable. Also, fix the Yoda condition: we want to check if remote is the same as the branch remote, not the other way around.

2021-02-25Merge branch 'jc/push-delete-nothing'Libravatar Junio C Hamano1-1/+1
"git push $there --delete ''" should have been diagnosed as an error, but instead turned into a matching push, which has been corrected. * jc/push-delete-nothing: push: do not turn --delete '' into a matching push
2021-02-23push: do not turn --delete '' into a matching pushLibravatar Junio C Hamano1-1/+1
When we added a syntax sugar "git push remote --delete <ref>" to "git push" as a synonym to the canonical "git push remote :<ref>" syntax at f517f1f2 (builtin-push: add --delete as syntactic sugar for :foo, 2009-12-30), we weren't careful enough to make sure that <ref> is not empty. Blindly rewriting "--delete <ref>" to ":<ref>" means that an empty string <ref> results in refspec ":", which is the syntax to ask for "matching" push that does not delete anything. Worse yet, if there were matching refs that can be fast-forwarded, they would have been published prematurely, even if the user feels that they are not ready yet to be pushed out, which would be a real disaster.

"git push --force-with-lease[=<ref>]" can easily be misused to lose commits unless the user takes good care of their own "git fetch".

2020-10-03push: parse and set flag for "--force-if-includes"Libravatar Srinidhi Kaushik1-0/+27
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.

2020-09-06push: release strbufs used for refspec formattingLibravatar René Scharfe1-12/+22
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. Signed-off-by: René Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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().

2020-04-28Use OPT_CALLBACK and OPT_CALLBACK_FLibravatar Denton Liu1-7/+5
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
2019-09-03push: disallow --all and refspecs when remote.<name>.mirror is setLibravatar Thomas Gummerer1-33/+36
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. *1*: https://twitter.com/FiloSottile/status/1163918701462249472 Reported-by: Filippo Valsorda <filippo@ml.filippo.io> Helped-by: Saleem Rashid Signed-off-by: Thomas Gummerer <t.gummerer@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-08-03push: use PARSE_OPT_LITERAL_ARGHELP instead of unbalanced bracketsLibravatar Ævar Arnfjörð Bjarmason1-2/+2
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.
