* refs: add option core.logAllRefUpdates = alwaysCornelius Weig2017-01-311-1/+6
| | | | | | | | | | | | | | | | | | | | | | | When core.logallrefupdates is true, we only create a new reflog for refs that are under certain well-known hierarchies. The reason is that we know that some hierarchies (like refs/tags) are not meant to change, and that unknown hierarchies might not want reflogs at all (e.g., a hypothetical refs/foo might be meant to change often and drop old history immediately). However, sometimes it is useful to override this decision and simply log for all refs, because the safety and audit trail is more important than the performance implications of keeping the log around. This patch introduces a new "always" mode for the core.logallrefupdates option which will log updates to everything under refs/, regardless where in the hierarchy it is (we still will not log things like ORIG_HEAD and FETCH_HEAD, which are known to be transient).

Unlike zlib_compression_level that controls the loose object compression, however, this variable was static to each of these codepaths. Two of them read the pack.compression configuration variable, using core.compression as the default, and one of them also allowed overriding it from the command line. The other codepath in bulk-checkin did not pay any attention to the configuration. Unify the configuration parsing to git_default_config(), where we implement the parsing of core.loosecompression and core.compression and make the former override the latter, by moving code to parse pack.compression and also allow core.compression to give default to this variable.

But if we don't, we fall back to treating all sha1s the same, even though most projects will tend to refer only to commits by their short sha1s. This patch introduces a configuration option that lets the user pick a different fallback (e.g., only commits). It's possible that we may want to make this the default, but it's a good idea to start as a config option for two reasons: 1. It lets people experiment with this and see if it's a good idea (i.e., the "tend to" above is an assumption; we don't really know if this will break some obscure cases). 2. Even if we do flip the default, it gives people an escape hatch if it causes problems (you can sometimes override it by asking for "1234^{tree}", but not all combinations are possible).

It gets the latter by calling git_pathdup(), which in turn calls get_git_dir(). If we haven't set up the git repository yet, this may simply return ".git", and we will look at ".git/config". This seems like it would be helpful (presumably we haven't set up the repository yet, so it tries to find it), but it turns out to be a bad idea for a few reasons: - it's not sufficient, and therefore hides bugs in a confusing way. Config will be respected if commands are run from the top-level of the working tree, but not from a subdirectory. - it's not always true that we haven't set up the repository _yet_; we may not want to do it at all. For instance, if you run "git init /some/path" from inside another repository, it should not load config from the existing repository. - there might be a path ".git/config", but it is not the actual repository we would find via setup_git_directory(). This may happen, e.g., if you are storing a git repository inside another git repository, but have munged one of the files in such a way that the inner repository is not valid (e.g., by removing HEAD). We have at least two bugs of the second type in git-init, introduced by ae5f677 (lazily load core.sharedrepository, 2016-03-11). It causes init to use git_configset(), which loads all of the config, including values from the current repo (if any). This shows up in two ways: 1. If we happen to be in an existing repository directory, we'll read and respect core.sharedrepository from it, even though it should have no bearing on the new repository. A new test in t1301 covers this. 2. Similarly, if we're in an existing repo that sets core.logallrefupdates, that will cause init to fail to set it in a newly created repository (because it thinks that the user's templates already did so). A new test in t0001 covers this. We also need to adjust an existing test in t1302, which gives another example of why this patch is an improvement. That test creates an embedded repository with a bogus core.repositoryformatversion of "99". It wants to make sure that we actually stop at the bogus repo rather than continuing upward to find the outer repo. So it checks that "git config core.repositoryformatversion" returns 99. But that only works because we blindly read ".git/config", even though we _know_ we're in a repository whose vintage we do not understand. After this patch, we avoid reading config from the unknown vintage repository at all, which is a safer choice. But we need to tweak the test, since core.repositoryformatversion will not return 99; it will claim that it could not find the variable at all.

| * | | pager: stop loading git_default_config()Jeff King2016-09-131-3/+0

But to do so, we use the git_default_config() callback, which loads many other values. Ordinarily it isn't a big deal to load this config an extra time, as it simply overwrites the values from the previous run. But it's a bad idea here, for two reasons: 1. The pager setup may be called very early in the program, before we have found the git repository. As a result, we may fail to read the correct repo-level config file. This is a problem for core.pager, too, but we should at least try to minimize the pollution to other configured values. 2. Because we call setup_pager() from git.c, basically every builtin command _may_ end up reading this config and getting an implicit git_default_config() setup. Which doesn't sound like a terrible thing, except that we don't do it consistently; it triggers only when stdout is a tty. So if a command forgets to load the default config itself (but depends on it anyway), it may appear to work, and then mysteriously fail when the pager is not in use. We can improve this by loading _just_ the core.pager config from git_pager(). Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Moreover, for the second message, a reason for the error is appended to the message, not allowing translators to translate that reason either. Unfold the message into several templates for each known origin_type. That would result in better translation at the expense of code verbosity. Add enum config_oringin_type to ease management of the various configuration origin types (blob, file, etc). Previously origin type was considered from command line if cf->origin_type == NULL, i.e., uninitialized. Now we set origin_type to CONFIG_ORIGIN_CMDLINE in git_config_from_parameters() and configset_add_value(). For error message in git_parse_source(), use xstrfmt() function to prepare the message string, instead of doing something like it's done for die_bad_number(), because intelligibility and code conciseness are improved for that instance.

It can ask whether the variable comes from a file, and get the file name. But without analyzing the filename (which is hard to do accurately), it cannot tell whether it is in system-level config, user-level config, or repo-specific config. Generally this doesn't matter; the point of not passing this to the callback is that it should treat the config the same no matter where it comes from. But some programs, like upload-pack, are a special case: we should be able to run them in an untrusted repository, which means we cannot use any "dangerous" config from the repository config file (but it is OK to use it from system or user config). This patch teaches the config code to record the "scope" of each variable, and make it available inside config callbacks, similar to how we give access to the filename. The scope is the starting source for a particular parsing operation, and remains the same even if we include other files (so a .git/config which includes another file will remain CONFIG_SCOPE_REPO, as it would be similarly untrusted).

This is sufficient to make it work with git-config, which uses git_config_with_options() under the hood. That function freshly parses the config files and triggers the callback when it parses each key. Most git programs, however, use git_config(). This interface will populate a cache during the actual parse, and then serve values from the cache. Calling current_config_filename() in a callback here will find a NULL cf and produce an error. There are no such callers right now, but let's prepare for adding some by making this work. We already record source information in a struct attached to each value. We just need to make it globally available and then consult it from the accessor functions. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This is used for error messages, as well as for lookup functions like current_config_name(). The "cf" variable is NULL in two cases: 1. When we are parsing command-line config, in which case there is no source file. 2. When we are not parsing any config at all. Callers like current_config_name() must assume we are in case 1 if they see a NULL "cf". However, this means that if they are accidentally used outside of a config parsing callback, they will quietly return a bogus answer. This might seem like an unlikely accident (why would you ask for the current config file if you are not parsing config?), but it's actually an easy mistake to make due to the configset caching. git_config() serves the answers from a configset cache, and any calls to current_config_name() will claim that we are parsing command-line config, no matter what the original source. So let's distinguish these cases by having the command-line config parser set up a config_source with a NULL name (which callers already handle properly). We can use this to catch programming errors in some cases, and to give better messages to the user in others.

Similarly, let's drop the "found anything" return from git_config_from_parameters, which was present only to support this (and similarly has never had other callers care for the past 5+ years).

This convention is used by Git: the .git/ directory should be left alone by regular users, and only accessed through Git itself. On Windows, no such convention exists. Instead, there is an explicit flag to mark files or directories as hidden. In the early days, Git for Windows did not mark the .git/ directory (or for that matter, any file or directory whose name starts with a dot) hidden. This lead to quite a bit of confusion, and even loss of data. Consequently, Git for Windows introduced the core.hideDotFiles setting, with three possible values: true, false, and dotGitOnly, defaulting to marking only the .git/ directory as hidden. The rationale: users do not need to access .git/ directly, and indeed (as was demonstrated) should not really see that directory, either. However, not all dot files should be hidden by default, as e.g. Eclipse does not show them (and the user would therefore be unable to see, say, a .gitattributes file). In over five years since the last attempt to bring this patch into core Git, a slightly buggy version of this patch has served Git for Windows' users well: no single report indicated problems with the hidden .git/ directory, and the stream of problems caused by the previously non-hidden .git/ directory simply stopped. The bugs have been fixed during the process of getting this patch upstream. Note that there is a funny quirk we have to pay attention to when creating hidden files: we use Win32's _wopen() function which transmogrifies its arguments and hands off to Win32's CreateFile() function. That latter function errors out with ERROR_ACCESS_DENIED (the equivalent of EACCES) when the equivalent of the O_CREAT flag was passed and the file attributes (including the hidden flag) do not match an existing file's. And _wopen() accepts no parameter that would be transmogrified into said hidden flag. Therefore, we simply try again without O_CREAT. A slightly different method is required for our fopen()/freopen() function as we cannot even *remove* the implicit O_CREAT flag. Therefore, we briefly mark existing files as unhidden when opening them via fopen()/freopen(). The ERROR_ACCESS_DENIED error can also be triggered by opening a file that is marked as a system file (which is unlikely to be tracked in Git), and by trying to create a file that has *just* been deleted and is awaiting the last open handles to be released (which would be handled better by the "Try again?" logic, a story for a different patch series, though). In both cases, it does not matter much if we try again without the O_CREAT flag, read: it does not hurt, either.

This is essentially a more intrusive version of the git-init ability to specify hooks on init time via init templates. The difference between that facility and this feature is that this can be set up after the fact via e.g. ~/.gitconfig or /etc/gitconfig to apply for all your personal repositories, or all repositories on the system. I plan on using this on a centralized Git server where users can create arbitrary repositories under /gitroot, but I'd like to manage all the hooks that should be run centrally via a unified dispatch mechanism.

When the config is later read via git_config() or similar, we parse it back out of that variable. The parsing end is a little bit picky; it assumes that each entry was generated with sq_quote_buf(), and that there is no extraneous whitespace. On the generating end, we are careful to append to an existing $GIT_CONFIG_PARAMETERS variable if it exists. However, our test for "should we add a space separator" is too liberal: it will add one even if the environment variable exists but is empty. As a result, you might end up with: GIT_CONFIG_PARAMETERS=" 'core.foo=bar'" which the parser will choke on. This was hard to trigger in older versions of git, since we only set the variable when we had something to put into it (though you could certainly trigger it manually). But since 14111fc (git: submodule honor -c credential.* from command line, 2016-02-29), the submodule code will unconditionally put the $GIT_CONFIG_PARAMETERS variable into the environment of any operation in the submodule, whether it is empty or not. So any of those operations which themselves use "git -c" will generate the unparseable value and fail. We can easily fix it by catching this case on the generating side. While we're adding a test, let's also check that multiple layers of "git -c" work, which was previously not tested at all.
