2024-05-07refs: accept symref values in `ref_transaction_update()`Karthik Nayak
The function `ref_transaction_update()` obtains ref information and flags to create a `ref_update` and add them to the transaction at hand. To extend symref support in transactions, we need to also accept the old and new ref targets and process it. This commit adds the required parameters to the function and modifies all call sites. The two parameters added are `new_target` and `old_target`. The `new_target` is used to denote what the reference should point to when the transaction is applied. Some functions allow this parameter to be NULL, meaning that the reference is not changed. The `old_target` denotes the value the reference must have before the update. Some functions allow this parameter to be NULL, meaning that the old value of the reference is not checked. We also update the internal function `ref_transaction_add_update()` similarly to take the two new parameters.

2024-04-15Merge branch 'ds/fetch-config-parse-microfix'Junio C Hamano
A config parser callback function fell through instead of returning after recognising and processing a variable, wasting cycles, which has been corrected. * ds/fetch-config-parse-microfix: fetch: return when parsing submodule.recurse
2024-04-05fetch: return when parsing submodule.recurseDerrick Stolee
When parsing config keys, the normal pattern is to return 0 after completing the logic for a specific config key, since no other key will match. One instance, for "submodule.recurse", was missing this case in builtin/fetch.c. This is a very minor change, and will have minimal impact to performance. This particular block was edited recently in 56e8bb4fb4 (fetch: use `fetch_config` to store "fetch.recurseSubmodules" value, 2023-05-17), which led to some hesitation that perhaps this omission was on purpose. However, no later cases within git_fetch_config() will match the key if equal to "submodule.recurse" and neither will any key matches within the catch-all git_default_config().

2024-02-28commit-reach(repo_in_merge_bases_many): report missing commitsJohannes Schindelin
Some functions in Git's source code follow the convention that returning a negative value indicates a fatal error, e.g. repository corruption. Let's use this convention in `repo_in_merge_bases()` to report when one of the specified commits is missing (i.e. when `repo_parse_commit()` reports an error). Also adjust the callers of `repo_in_merge_bases()` to handle such negative return values. Note: As of this patch, errors are returned only if any of the specified merge heads is missing. Over the course of the next patches, missing commits will also be reported by the `paint_down_to_common()` function, which is called by `repo_in_merge_bases_many()`, and those errors will be properly propagated back to the caller at that stage.

2023-12-18fetch: no redundant error message for atomic fetchJiang Xin
If an error occurs during an atomic fetch, a redundant error message will appear at the end of do_fetch(). It was introduced in b3a804663c (fetch: make `--atomic` flag cover backfilling of tags, 2022-02-17). Because a failure message is displayed before setting retcode in the function do_fetch(), calling error() on the err message at the end of this function may result in redundant or empty error message to be displayed. We can remove the redundant error() function, because we know that the function ref_transaction_abort() never fails. While we can find a common pattern for calling ref_transaction_abort() by running command "git grep -A1 ref_transaction_abort", e.g.: if (ref_transaction_abort(transaction, &error)) error("abort: %s", error.buf); Following this pattern, we can tolerate the return value of the function ref_transaction_abort() being changed in the future. We also delay the output of the err message to the end of do_fetch() to reduce redundant code. With these changes, the test case "fetch porcelain output (atomic)" in t5574 will also be fixed.

2023-09-05parse-options: prefer opt->value to globals in callbacksJeff King
We have several parse-options callbacks that ignore their "opt" parameters entirely. This is a little unusual, as we'd normally put the result of the parsing into opt->value. In the case of these callbacks, though, they directly manipulate global variables instead (and in most cases the caller sets opt->value to NULL in the OPT_CALLBACK declaration). The immediate symptom we'd like to deal with is that the unused "opt" variables trigger -Wunused-parameter. But how to fix that is debatable. One option is to annotate them with UNUSED. But another is to have the caller pass in the appropriate variable via opt->value, and use it. That has the benefit of making the callbacks reusable (in theory at least), and makes it clear from the OPT_CALLBACK declaration which variables will be affected (doubly so for the cases in builtin/fast-export.c, where we do set opt->value, but it is completely ignored!). The slight downside is that we lose type safety, since they're now passing through void pointers. I went with the "just use them" approach here. The loss of type safety is unfortunate, but that is already an issue with most of the other callbacks. If we want to try to address that, we should do so more consistently (and this patch would prepare these callbacks for whatever we choose to do there). Note that in the cases in builtin/fast-export.c, we are passing anonymous enums. We'll have to give them names so that we can declare the appropriate pointer type within the callbacks.

2023-06-28config: pass kvi to die_bad_number()Glen Choo
Plumb "struct key_value_info" through all code paths that end in die_bad_number(), which lets us remove the helper functions that read analogous values from "struct config_reader". As a result, nothing reads config_reader.config_kvi any more, so remove that too. In config.c, this requires changing the signature of git_configset_get_value() to 'return' "kvi" in an out parameter so that git_configset_get_<type>() can pass it to git_config_<type>(). Only numeric types will use "kvi", so for non-numeric types (e.g. git_configset_get_string()), pass NULL to indicate that the out parameter isn't needed. Outside of config.c, config callbacks now need to pass "ctx->kvi" to any of the git_config_<type>() functions that parse a config string into a number type. Included is a .cocci patch to make that refactor. The only exceptional case is builtin/config.c, where git_config_<type>() is called outside of a config callback (namely, on user-provided input), so config source information has never been available. In this case, die_bad_number() defaults to a generic, but perfectly descriptive message. Let's provide a safe, non-NULL for "kvi" anyway, but make sure not to change the message.

2023-06-28config: add ctx arg to config_fn_tGlen Choo
Add a new "const struct config_context *ctx" arg to config_fn_t to hold additional information about the config iteration operation. config_context has a "struct key_value_info kvi" member that holds metadata about the config source being read (e.g. what kind of config source it is, the filename, etc). In this series, we're only interested in .kvi, so we could have just used "struct key_value_info" as an arg, but config_context makes it possible to add/adjust members in the future without changing the config_fn_t signature. We could also consider other ways of organizing the args (e.g. moving the config name and value into config_context or key_value_info), but in my experiments, the incremental benefit doesn't justify the added complexity (e.g. a config_fn_t will sometimes invoke another config_fn_t but with a different config value). In subsequent commits, the .kvi member will replace the global "struct config_reader" in config.c, making config iteration a global-free operation. It requires much more work for the machinery to provide meaningful values of .kvi, so for now, merely change the signature and call sites, pass NULL as a placeholder value, and don't rely on the arg in any meaningful way. Most of the changes are performed by contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every config_fn_t: - Modifies the signature to accept "const struct config_context *ctx" - Passes "ctx" to any inner config_fn_t, if needed - Adds UNUSED attributes to "ctx", if needed Most config_fn_t instances are easily identified by seeing if they are called by the various config functions. Most of the remaining ones are manually named in the .cocci patch. Manual cleanups are still needed, but the majority of it is trivial; it's either adjusting config_fn_t that the .cocci patch didn't catch, or adding forward declarations of "struct config_context ctx" to make the signatures make sense. The non-trivial changes are in cases where we are invoking a config_fn_t outside of config machinery, and we now need to decide what value of "ctx" to pass. These cases are: - trace2/tr2_cfg.c:tr2_cfg_set_fl() This is indirectly called by git_config_set() so that the trace2 machinery can notice the new config values and update its settings using the tr2 config parsing function, i.e. tr2_cfg_cb(). - builtin/checkout.c:checkout_main() This calls git_xmerge_config() as a shorthand for parsing a CLI arg. This might be worth refactoring away in the future, since git_xmerge_config() can call git_default_config(), which can do much more than just parsing. Handle them by creating a KVI_INIT macro that initializes "struct key_value_info" to a reasonable default, and use that to construct the "ctx" arg.

2023-05-10fetch: introduce machine-parseable "porcelain" output formatPatrick Steinhardt
The output of git-fetch(1) is obviously designed for consumption by users, only: we neatly columnize data, we abbreviate reference names, we print neat arrows and we don't provide information about actual object IDs that have changed. This makes the output format basically unusable in the context of scripted invocations of git-fetch(1) that want to learn about the exact changes that the command performs. Introduce a new machine-parseable "porcelain" output format that is supposed to fix this shortcoming. This output format is intended to provide information about every reference that is about to be updated, the old object ID that the reference has been pointing to and the new object ID it will be updated to. Furthermore, the output format provides the same flags as the human-readable format to indicate basic conditions for each reference update like whether it was a fast-forward update, a branch deletion, a rejected update or others. The output format is quite simple: ``` <flag> <old-object-id> <new-object-id> <local-reference>\n ``` We assume two conditions which are generally true: - The old and new object IDs have fixed known widths and cannot contain spaces. - References cannot contain newlines. With these assumptions, the output format becomes unambiguously parseable. Furthermore, given that this output is designed to be consumed by scripts, the machine-readable data is printed to stdout instead of stderr like the human-readable output is. This is mostly done so that other data printed to stderr, like error messages or progress meters, don't interfere with the parseable data. A notable ommission here is that the output format does not include the remote from which a reference was fetched, which might be important information especially in the context of multi-remote fetches. But as such a format would require us to print the remote for every single reference update due to parallelizable fetches it feels wasteful for the most likely usecase, which is when fetching from a single remote. In a similar spirit, a second restriction is that this cannot be used with `--recurse-submodules`. This is because any reference updates would be ambiguous without also printing the repository in which the update happens. Considering that both multi-remote and submodule fetches are user-facing features, using them in conjunction with `--porcelain` that is intended for scripting purposes is likely not going to be useful in the majority of cases. With that in mind these restrictions feel acceptable. If usecases for either of these come up in the future though it is easy enough to add a new "porcelain-v2" format that adds this information.

2023-05-10fetch: lift up parsing of "fetch.output" config variablePatrick Steinhardt
Parsing the display format happens inside of `display_state_init()`. As we only need to check for a simple config entry, this is a natural location to put this code as it means that display-state logic is neatly contained in a single location. We're about to introduce a new "porcelain" output format though that is intended to be parseable by machines, for example inside of a script. This format can be enabled by passing the `--porcelain` switch to git-fetch(1). As a consequence, we'll have to add a second callsite that influences the output format, which will become awkward to handle. Refactor the code such that callers are expected to pass the display format that is to be used into `display_state_init()`. This allows us to lift up the code into the main function, where we can then hook it into command line options parser in a follow-up commit.

2023-05-10fetch: refactor calculation of the display table widthPatrick Steinhardt
When displaying reference updates, we try to print the references in a neat table. As the table's width is determined its contents we thus need to precalculate the overall width before we can start printing updated references. The calculation is driven by `display_state_init()`, which invokes `refcol_width()` for every reference that is to be printed. This split is somewhat confusing. For one, we filter references that shall be attributed to the overall width in both places. And second, we needlessly recalculate the maximum line length based on the terminal columns and display format for every reference. Refactor the code so that the complete width calculations are neatly contained in `refcol_width()`. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2023-05-10fetch: print left-hand side when fetching HEAD:fooPatrick Steinhardt
`store_updated_refs()` parses the remote reference for two purposes: - It gets used as a note when writing FETCH_HEAD. - It is passed through to `display_ref_update()` to display updated references in the following format: ``` * branch master -> master ``` In most cases, the parsed remote reference is the prettified reference name and can thus be used for both cases. But if the remote reference is HEAD, the parsed remote reference becomes empty. This is intended when we write the FETCH_HEAD, where we skip writing the note in that case. But when displaying the updated references this leads to inconsistent output where the left-hand side of reference updates is missing in some cases: ``` $ git fetch origin HEAD HEAD:explicit-head :implicit-head main From https://github.com/git/git * branch HEAD -> FETCH_HEAD * [new ref] -> explicit-head * [new ref] -> implicit-head * branch main -> FETCH_HEAD ``` This behaviour has existed ever since the table-based output has been introduced for git-fetch(1) via 165f390250 (git-fetch: more terse fetch output, 2007-11-03) and was never explicitly documented either in the commit message or in any of our tests. So while it may not be a bug per se, it feels like a weird inconsistency and not like it was a concious design decision. The logic of how we compute the remote reference name that we ultimately pass to `display_ref_update()` is not easy to follow. There are three different cases here: - When the remote reference name is "HEAD" we set the remote reference name to the empty string. This is the case that causes the left-hand side to go missing, where we would indeed want to print "HEAD" instead of the empty string. This is what `prettify_refname()` would return. - When the remote reference name has a well-known prefix then we strip this prefix. This matches what `prettify_refname()` does. - Otherwise, we keep the fully qualified reference name. This also matches what `prettify_refname()` does. As the return value of `prettify_refname()` would do the correct thing for us in all three cases, we can thus fix the inconsistency by passing through the full remote reference name to `display_ref_update()`, which learns to call `prettify_refname()`. At the same time, this also simplifies the code a bit. Note that this patch also changes formatting of the block that computes the "kind" (which is the category like "branch" or "tag") and "what" (which is the prettified reference name like "master" or "v1.0") variables. This is done on purpose so that it is part of the diff, hopefully making the change easier to comprehend.

2023-05-10fetch: fix `--no-recurse-submodules` with multi-remote fetchesPatrick Steinhardt
When running `git fetch --no-recurse-submodules`, the exectation is that we don't fetch any submodules. And while this works for fetches of a single remote, it doesn't when fetching multiple remotes at once. The result is that we do recurse into submodules even though the user has explicitly asked us not to. This is because while we pass on `--recurse-submodules={yes,on-demand}` if specified by the user, we don't pass on `--no-recurse-submodules` to the subprocess spawned to perform the submodule fetch. Fix this by also forwarding this flag as expected. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
