2021-01-15config: parse more robust format in GIT_CONFIG_PARAMETERSLibravatar Jeff King2-17/+104
When we stuff config options into GIT_CONFIG_PARAMETERS, we shell-quote each one as a single unit, like: 'section.one=value1' 'section.two=value2' On the reading side, we de-quote to get the individual strings, and then parse them by splitting on the first "=" we find. This format is ambiguous, because an "=" may appear in a subsection. So the config represented in a file by both: [section "subsection=with=equals"] key = value and: [section] subsection = with=equals.key=value ends up in this flattened format like: 'section.subsection=with=equals.key=value' and we can't tell which was desired. We have traditionally resolved this by taking the first "=" we see starting from the left, meaning that we allowed arbitrary content in the value, but not in the subsection. Let's make our environment format a bit more robust by separately quoting the key and value. That turns those examples into: 'section.subsection=with=equals.key'='value' and: 'section.subsection'='with=equals.key=value' respectively, and we can tell the difference between them. We can detect which format is in use for any given element of the list based on the presence of the unquoted "=". That means we can continue to allow the old format to work to support any callers which manually used the old format, and we can even intermingle the two formats. The old format wasn't documented, and nobody was supposed to be using it. But it's likely that such callers exist in the wild, so it's nice if we can avoid breaking them. Likewise, it may be possible to trigger an older version of "git -c" that runs a script that calls into a newer version of "git -c"; that new version would see the intermingled format. This does create one complication, which is that the obvious format in the new scheme for [section] some-bool is: 'section.some-bool' with no equals. We'd mistake that for an old-style variable. And it even has the same meaning in the old style, but: [section "with=equals"] some-bool does not. It would be: 'section.with=equals=some-bool' which we'd take to mean: [section] with = equals=some-bool in the old, ambiguous style. Likewise, we can't use: 'section.some-bool'='' because that's ambiguous with an actual empty string. Instead, we'll again use the shell-quoting to give us a hint, and use: 'section.some-bool'= to show that we have no value. Note that this commit just expands the reading side. We'll start writing the new format via "git -c" in a future patch. In the meantime, the existing "git -c" tests will make sure we didn't break reading the old format. But we'll also add some explicit coverage of the two formats to make sure we continue to handle the old one after we move the writing side over. And one final note: since we're now using the shell-quoting as a semantically meaningful hint, this closes the door to us ever allowing arbitrary shell quoting, like: 'a'shell'would'be'ok'with'this'.key=value But we have never supported that (only what sq_quote() would produce), and we are probably better off keeping things simple, robust, and backwards-compatible, than trying to make it easier for humans. We'll continue not to advertise the format of the variable to users, and instead keep "git -c" as the recommended mechanism for setting config (even if we are trying to be kind not to break users who may be relying on the current undocumented format).

2021-01-12config: extract function to parse config pairsLibravatar Patrick Steinhardt1-7/+17
The function `git_config_parse_parameter` is responsible for parsing a `foo.bar=baz`-formatted configuration key, sanitizing the key and then processing it via the given callback function. Given that we're about to add a second user which is going to process keys which already has keys and values separated, this commit extracts a function `config_parse_pair` which only does the sanitization and processing part as a preparatory step.

2021-01-12quote: make sq_dequote_step() a public functionLibravatar Jeff King2-7/+26
We provide a function for dequoting an entire string, as well as one for handling a space-separated list of quoted strings. But there's no way for a caller to parse a string like 'foo'='bar', even though it is easy to generate one using sq_quote_buf() or similar. Let's make the single-step function available to callers outside of quote.c. Note that we do need to adjust its implementation slightly: it insists on seeing whitespace between items, and we'd like to be more flexible than that. Since it only has a single caller, we can move that check (and slurping up any extra whitespace) into that caller.

2021-01-12config: add new way to pass config via `--config-env`Libravatar Patrick Steinhardt5-2/+100
While it's already possible to pass runtime configuration via `git -c <key>=<value>`, it may be undesirable to use when the value contains sensitive information. E.g. if one wants to set `http.extraHeader` to contain an authentication token, doing so via `-c` would trivially leak those credentials via e.g. ps(1), which typically also shows command arguments. To enable this usecase without leaking credentials, this commit introduces a new switch `--config-env=<key>=<envvar>`. Instead of directly passing a value for the given key, it instead allows the user to specify the name of an environment variable. The value of that variable will then be used as value of the key.

2021-01-06git: add `--super-prefix` to usage stringLibravatar Patrick Steinhardt1-0/+1
When the `--super-prefix` option was implmented in 74866d7579 (git: make super-prefix option, 2016-10-07), its existence was only documented in the manpage but not in the command's own usage string. Given that the commit message didn't mention that this was done intentionally and given that it's documented in the manpage, this seems like an oversight. Add it to the usage string to fix the inconsistency. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-11-11mergetool: avoid letting `list_tool_variants` break user-defined setupsLibravatar Johannes Schindelin1-0/+4
In 83bbf9b92ea8 (mergetool--lib: improve support for vimdiff-style tool variants, 2020-07-29), we introduced a `list_tool_variants` function in the spirit of Postel's Law: be lenient in what you accept as input. In this particular instance, we wanted to allow not only `bc` but also `bc3` as name for the Beyond Compare tool. However, what this patch overlooked is that it is totally allowed for users to override the defaults in `mergetools/`. But now that we strip off trailing digits, the name that the user gave the tool might not actually be in the list produced by `list_tool_variants`. So let's do the same as for the `diff_cmd` and the `merge_cmd`: override it with the trivial version in case a user-defined setup was detected.

2020-11-11mergetools/bc: add `bc4` to the alias list for Beyond CompareLibravatar Johannes Schindelin1-0/+1
As of 83bbf9b92ea8 (mergetool--lib: improve support for vimdiff-style tool variants, 2020-07-29), we already list `bc` and `bc3` as aliases for that mergetool/difftool. However, the current Beyond Compare version is _4_, therefore the `bc4` alias is missing from that list. Most notably, this is the root cause of the breakage reported in https://github.com/git-for-windows/git/issues/2893 where a well-configured `bc4` difftool stopped working as of v2.29.0: `setup_tool` would notice that after stripping off the trailing digit, it finds a match in `mergetools/` (the `bc` file), source it, and then the alias would not match the list offered by the `list_tool_variants` function, and simply exit without doing anything, but pretending success.

By default, we do not use a mempool and strdup_strings is true; in this case, we can avoid both an extra allocation and an extra free by just over-allocating for the strmap_entry leaving enough space at the end to copy the key. FLEXPTR_ALLOC_STR exists for exactly this purpose, so make use of it. Also, adjust the case when we are using a memory pool and strdup_strings is true to just do one allocation from the memory pool instead of two so that the strmap_clear() and strmap_remove() code can just avoid freeing the key in all cases.
