2020-12-21gc: fix handling of crontab magic markersLibravatar Martin Ågren1-4/+3
On `git maintenance start`, we add a few entries to the user's cron table. We wrap our entries using two magic markers, "# BEGIN GIT MAINTENANCE SCHEDULE" and "# END GIT MAINTENANCE SCHEDULE". At a later `git maintenance stop`, we will go through the table and remove these lines. Or rather, we will remove the "BEGIN" marker, the "END" marker and everything between them. Alas, we have a bug in how we detect the "END" marker: we don't. As we loop through all the lines of the crontab, if we are in the "old region", i.e., the region we're aiming to remove, we make an early `continue` and don't get as far as checking for the "END" marker. Thus, once we've seen our "BEGIN", we remove everything until the end of the file. Rewrite the logic for identifying these markers. There are four cases that are mutually exclusive: The current line starts a region or it ends it, or it's firmly within the region, or it's outside of it (and should be printed).

2020-12-21checkout -p: handle tree arguments correctly againLibravatar Johannes Schindelin1-2/+4
This fixes a segmentation fault. The bug is caused by dereferencing `new_branch_info->commit` when it is `NULL`, which is the case when the tree-ish argument is actually a tree, not a commit-ish. This was introduced in 5602b500c3c (builtin/checkout: fix `git checkout -p HEAD...` bug, 2020-10-07), where we tried to ensure that the special tree-ish `HEAD...` is handled correctly.

2020-12-15style: do not "break" in switch() after "return"Libravatar Ævar Arnfjörð Bjarmason1-1/+0
Remove this unreachable code. It was found by SunCC, it's found by a non-fatal warning emitted by SunCC. It's one of the things it's more vehement about than GCC & Clang. It complains about a lot of other similarly unreachable code, e.g. a BUG(...) without a "return", and a "return 0" after a long if/else, both of whom have "return" statements. Those are also genuine redundancies to a compiler, but arguably make the code a bit easier to read & less fragile to maintain. These return/break cases are just unnecessary however, and as seen here the surrounding code just did a plain "return" without a "break" already.

We are about to introduce a message giving users running `git init` some advice about `init.defaultBranch`. This will necessarily be done in `repo_default_branch_name()`. Not all code paths want to show that advice, though. In particular, the `git clone` codepath _specifically_ asks for `init_db()` to be quiet, via the `INIT_DB_QUIET` flag.

2020-12-03builtin/clone.c: don't ignore transport_fetch_refs() errorsLibravatar Taylor Blau1-4/+11
If 'git clone' couldn't execute 'transport_fetch_refs()' (e.g., because of an error on the remote's side in 'git upload-pack'), then it will silently ignore it. Even though this has been the case at least since clone was ported to C (way back in 8434c2f1af (Build in clone, 2008-04-27)), 'git fetch' doesn't ignore these and reports any failures it sees. That suggests that ignoring the return value in 'git clone' is simply an oversight that should be corrected. That's exactly what this patch does. (Noticing and fixing this is no coincidence, we'll want it in the next patch in order to demonstrate a regression in 'git upload-pack' via a 'git clone'.) There's no additional logging here, but that matches how 'git fetch' handles the same case. An assumption there is that whichever part of transport_fetch_refs() fails will complain loudly, so any additional logging here is redundant.

2020-12-01builtin/bugreport.c: use thread-safe localtime_r()Libravatar Taylor Blau1-1/+2
To generate its filename, the 'git bugreport' builtin asks the system for the current time with 'localtime()'. Since this uses a shared buffer, it is not thread-safe. Even though 'git bugreport' is not multi-threaded, using localtime() can trigger some static analysis tools to complain, and a quick $ git grep -oh 'localtime\(_.\)\?' -- **/*.c | sort | uniq -c shows that the only usage of the thread-unsafe 'localtime' is in a piece of documentation. So, convert this instance to use the thread-safe version for consistency, and to appease some analysis tools.

2020-11-30maintenance: fix SEGFAULT when no repositoryLibravatar Rafael Silva1-7/+0
The "git maintenance run" and "git maintenance start/stop" commands holds a file-based lock at the .git/maintenance.lock and .git/schedule.lock respectively. These locks are used to ensure only one maintenance process is executed at the time as both operations involves writing data into the git repository. The path to the lock file is built using "the_repository->objects->odb->path" that results in SEGFAULT when we have no repository available as "the_repository->objects->odb" is set to NULL. Let's teach maintenance command to use RUN_SETUP option that will provide the validation and fail when running outside of a repository. Hence fixing the SEGFAULT for all three operations and making the behaviour consistent across all subcommands. Setting the RUN_SETUP also provides the same protection for all subcommands given that the "register" and "unregister" also requires to be executed inside a repository. Furthermore let's remove the local validation implemented by the "register" and "unregister" as this will not be required anymore with the new option.

2020-11-25maintenance: use 'git config --fixed-value'Libravatar Derrick Stolee1-2/+3
When a repository's leading directories contain regex metacharacters, the config calls for 'git maintenance register' and 'git maintenance unregister' are not careful enough. Use the new --fixed-value option to direct the config machinery to use exact string matches. This is a more robust option than escaping these arguments in a piecemeal fashion. For the test, require that we are not running on Windows since the '+' and '*' characters are not allowed on that filesystem.

2020-11-25config: plumb --fixed-value into config APILibravatar Derrick Stolee1-5/+11
The git_config_set_multivar_in_file_gently() and related methods now take a 'flags' bitfield, so add a new bit representing the --fixed-value option from 'git config'. This alters the purpose of the value_pattern parameter to be an exact string match. This requires some initialization changes in git_config_set_multivar_in_file_gently() and a new strcmp() call in the matches() method. The new CONFIG_FLAGS_FIXED_VALUE flag is initialized in builtin/config.c based on the --fixed-value option, and that needs to be updated in several callers. This patch only affects some of the modes of 'git config', and the rest will be completed in the next change.

2020-11-25config: add --fixed-value option, un-implementedLibravatar Derrick Stolee1-0/+36
The 'git config' builtin takes a 'value-pattern' parameter for several actions. This can cause confusion when expecting exact value matches instead of regex matches, especially when the input string contains metacharacters. While callers can escape the patterns themselves, it would be more friendly to allow an argument to disable the pattern matching in favor of an exact string match. Add a new '--fixed-value' option that does not currently change the behavior. The implementation will be filled in by later changes for each appropriate action. For now, check and test that --fixed-value will abort the command when included with an incompatible action or without a 'value-pattern' argument. The name '--fixed-value' was chosen over something simpler like '--fixed' because some commands allow regular expressions on the key in addition to the value.

2020-11-25config: replace 'value_regex' with 'value_pattern'Libravatar Derrick Stolee1-6/+6
The 'value_regex' argument in the 'git config' builtin is poorly named, especially related to an upcoming change that allows exact string matches instead of ERE pattern matches. Perform a mostly mechanical change of every instance of 'value_regex' to 'value_pattern' in the codebase. This is only critical for documentation and error messages, but it is best to be consistent inside the codebase, too. For documentation, use 'value-pattern' which is better punctuation. This affects Documentation/git-config.txt and the usage in builtin/config.c, which was already mixed between 'value_regex' and 'value-regex'. I gave some thought to leaving the value_regex variables inside config.c that are regex_t pointers. However, it is probably best to keep the name consistent with the rest of the variables. This does not update the translations inside the po/ directory, as that creates conflicts with ongoing work. The input strings should automatically update through automation, and a few of the output strings currently use "[value_regex]" directly.

To add more clarity, extend the documentation of git_config_set_multivar_in_file() including a clear labeling of its arguments.

`init_grep_defaults()` fills a `static struct grep_opt grep_defaults`. This struct is then used by `grep_init()` as a blueprint for other such structs. Notably, `grep_init()` takes a `struct repo *` and assigns it into the target struct. As a result, it is unnecessary for us to take a `struct repo *` in `init_grep_defaults()` as well. We assign it into the default struct and never look at it again. And in light of how we return early if we have already set up the default struct, it's not just unnecessary, but is also a bit confusing: If we are called twice and with different repos, is it a bug or a feature that we ignore the second repo?
