The point of disallowing ".git" in the index is that we would never want to accidentally overwrite files in the repository directory. But this means we need to respect the filesystem's idea of when two paths are equal. The prior commit added a helper to make such a comparison for HFS+; let's use it in verify_path. We make this check optional for two reasons: 1. It restricts the set of allowable filenames, which is unnecessary for people who are not on HFS+. In practice this probably doesn't matter, though, as the restricted names are rather obscure and almost certainly would never come up in practice. 2. It has a minor performance penalty for every path we insert into the index. This patch ties the check to the core.protectHFS config option. Though this is expected to be most useful on OS X, we allow it to be set everywhere, as HFS+ may be mounted on other platforms. The variable does default to on for OS X, though.

Commit 7192777d refactors git_parse_ulong, which is public, into a more generic function. But since we kept the git_parse_ulong wrapper, only that part needs to be public; nobody outside the file calls the lower-level git_parse_unsigned. Noticed with sparse.

When you run "git config --int", the maximum size of integer you get depends on how git was compiled, and what it considers to be an "int". This is almost useful, because your scripts calling "git config" will behave similarly to git internally. But relying on this is dubious; you have to actually know how git treats each value internally (e.g., int versus unsigned long), which is not documented and is subject to change. And even if you know it is "unsigned long", we do not have a git-config option to match that behavior. Furthermore, you may simply be asking git to store a value on your behalf (e.g., configuration for a hook). In that case, the relevant range check has nothing at all to do with git, but rather with whatever scripting tools you are using (and git has no way of knowing what the appropriate range is there). Not only is the range check useless, but it is actively harmful, as there is no way at all for scripts to look at config variables with large values. For instance, one cannot reliably get the value of pack.packSizeLimit via git-config. On an LP64 system, git happily uses a 64-bit "unsigned long" internally to represent the value, but the script cannot read any value over 2G. Ideally, the "--int" option would simply represent an arbitrarily large integer. For practical purposes, however, a 64-bit integer is large enough, and is much easier to implement (and if somebody overflows it, we will still notice the problem, and not simply return garbage).

If we try to parse an integer config argument and get a number outside of the representable range, we die with the cryptic message: "bad config value for '%s'". We can improve two things: 1. Show the value that produced the error (e.g., bad config value '3g' for 'foo.bar'). 2. Mention the reason the value was rejected (e.g., "invalid unit" versus "out of range"). A few tests need to be updated with the new output, but that should not be representative of real-world breakage, as scripts should not be depending on the exact text of our stderr output, which is subject to i18n anyway.

When we are parsing an integer or unsigned long, we use the strto*max functions, which properly set errno to ERANGE if we get a large value. However, we also do further range checks after applying our multiplication factor, but do not set ERANGE. This means that a caller cannot tell if an error was caused by ERANGE or if the input was simply not a valid number. This patch teaches git_parse_signed and git_parse_unsigned to set ERANGE for range errors, and EINVAL for other errors, so that the caller can reliably tell these cases apart.

When we look at a config value as an integer using the git_config_int function, we carefully range-check the value we get and complain if it is out of our range. But the range we compare to is that of a "long", which we then cast to an "int" in the function's return value. This means that on systems where "int" and "long" have different sizes (e.g., LP64 systems), we may pass the range check, but then return nonsense by truncating the value as we cast it to an int. We can solve this by converting git_parse_long into git_parse_int, and range-checking the "int" range. Nobody actually cared that we used a "long" internally, since the result was truncated anyway. And the only other caller of git_parse_long is git_config_maybe_bool, which should be fine to just use int (though we will now forbid out-of-range nonsense like setting "merge.ff" to "10g" to mean "true", which is probably a good thing).

When we are parsing integers for config, we use an intmax_t (or uintmax_t) internally, and then check against the size of our result type at the end. We can parameterize the maximum representable value, which will let us re-use the parsing code for a variety of range checks. Unfortunately, we cannot combine the signed and unsigned parsing functions easily, as we have to rely on the signed and unsigned C types internally.

According to C99, section 7.1.4: Any function declared in a header may be additionally implemented as a function-like macro defined in the header. Therefore calling our struct member function pointer "fgetc" may run afoul of unwanted macro expansion when we call: char c = cf->fgetc(cf); This turned out to be a problem on uclibc, which defines fgetc as a macro and causes compilation failure. The standard suggests fixing this in a few ways: 1. Using extra parentheses to inhibit the function-like macro expansion. E.g., "(cf->fgetc)(cf)". This is undesirable as it's ugly, and each call site needs to remember to use it (and on systems without the macro, forgetting will compile just fine). 2. Using #undef (because a conforming implementation must also be providing fgetc as a function). This is undesirable because presumably the implementation was using the macro for a performance benefit, and we are dropping that optimization. Instead, we can simply use non-colliding names.

The changes v1.7.12.1~2^2~4 (config: warn on inaccessible files, 2012-08-21) and v1.8.1.1~22^2~2 (config: treat user and xdg config permission problems as errors, 2012-10-13) were intended to prevent important configuration (think "[transfer] fsckobjects") from being ignored when the configuration is unintentionally unreadable (for example with EIO on a flaky filesystem, or with ENOMEM due to a DoS attack). Usually ~/.gitconfig and ~/.config/git are readable by the current user, and if they aren't then it would be easy to fix those permissions, so the damage from adding this check should have been minimal. Unfortunately the access() check often trips when git is being run as a server. A daemon (such as inetd or git-daemon) starts as "root", creates a listening socket, and then drops privileges, meaning that when git commands are invoked they cannot access $HOME and die with fatal: unable to access '/root/.config/git/config': Permission denied Any patch to fix this would have one of three problems: 1. We annoy sysadmins who need to take an extra step to handle HOME when dropping privileges (the current behavior, or any other proposal that they have to opt into). 2. We annoy sysadmins who want to set HOME when dropping privileges, either by making what they want to do impossible, or making them set an extra variable or option to accomplish what used to work (e.g., a patch to git-daemon to set HOME when --user is passed). 3. We loosen the check, so some cases which might be noteworthy are not caught. This patch is of type (3). Treat user and xdg configuration that are inaccessible due to permissions (EACCES) as though no user configuration was provided at all. An alternative method would be to check if $HOME is readable, but that would not help in cases where the user who dropped privileges had a globally readable HOME with only .config or .gitconfig being private. This does not change the behavior when /etc/gitconfig or .git/config is unreadable (since those are more serious configuration errors), nor when ~/.gitconfig or ~/.config/git is unreadable due to problems other than permissions.

For matching keys without subsections, it is simple enough to call "strcmp".

Specifically the fields uid, gid, ctime, ino and dev are set to zero by JGit. Other implementations, eg. Git in cygwin are allegedly also somewhat incompatible with Git For Windows and on *nix platforms the resolution of the timestamps may differ. Any stat checking by git will then need to check content, which may be very slow, particularly on Windows. Since mtime and size is typically enough we should allow the user to tell git to avoid checking these fields if they are set to zero in the index. This change introduces a core.checkstat config option where the the user can select to check all fields (default), or just size and the whole second part of mtime (minimal).

There are a few error functions that simply wrap error() and provide a standardized message text. Like error(), they always return -1; knowing that can help the compiler silence some false positive -Wuninitialized warnings. One strategy would be to just declare these as inline in the header file so that the compiler can see that they always return -1. However, gcc does not always inline them (e.g., it will not inline opterror, even with -O3), which renders our change pointless. Instead, let's follow the same route we did with error() in the last patch, and define a macro that makes the constant return value obvious to the compiler.

There is convenience in warning and moving on when somebody has a bogus permissions on /etc/gitconfig and cannot do anything about it. But the cost in predictability and security is too high --- when unreadable config files are skipped, it means an I/O error or permissions problem causes important configuration to be bypassed. For example, servers may depend on /etc/gitconfig to enforce security policy (setting transfer.fsckObjects or receive.deny*). Best to always error out when encountering trouble accessing a config file. This may add inconvenience in some cases: 1. You are inspecting somebody else's repo, and you do not have access to their .git/config file. Git typically dies in this case already since we cannot read core.repositoryFormatVersion, so the change should not be too noticeable. 2. You have used "sudo -u" or a similar tool to switch uid, and your environment still points Git at your original user's global config, which is not readable. In this case people really would be inconvenienced (they would rather see the harmless warning and continue the operation) but they can work around it by setting HOME appropriately after switching uids. 3. You do not have access to /etc/gitconfig due to a broken setup. In this case, erroring out is a good way to put pressure on the sysadmin to fix the setup. While they wait for a reply, users can set GIT_CONFIG_NOSYSTEM to true to keep Git working without complaint. After this patch, errors accessing the repository-local and systemwide config files and files requested in include directives cause Git to exit, just like errors accessing ~/.gitconfig.

Git reads multiple configuration files: settings come first from the system config file (typically /etc/gitconfig), then the xdg config file (typically ~/.config/git/config), then the user's dotfile (~/.gitconfig), then the repository configuration (.git/config). Git has always used access(2) to decide whether to use each file; as an unfortunate side effect, that means that if one of these files is unreadable (e.g., EPERM or EIO), git skips it. So if I use ~/.gitconfig to override some settings but make a mistake and give it the wrong permissions then I am subject to the settings the sysadmin chose for /etc/gitconfig. Better to error out and ask the user to correct the problem. This only affects the user and xdg config files, since the user presumably has enough access to fix their permissions. If the system config file is unreadable, the best we can do is to warn about it so the user knows to notify someone and get on with work in the meantime.

Previously while reading the variable names in config files, there was a 256 character limit with at most 128 of those characters being used by the section header portion of the variable name. This limitation was only enforced while reading the config files. It was possible to write a config file that was not subsequently readable. Instead of enforcing this limitation for both reading and writing, remove it entirely by changing the var member of the config_file struct to a strbuf instead of a fixed length buffer. Update all of the parsing functions in config.c to use the strbuf instead of the static buffer. The parsing functions that returned the base length of the variable name now return simply 0 for success and -1 for failure. The base length information is obtained through the strbuf's len member. We now send the buf member of the strbuf to external callback functions to preserve the external api. None of the external callers rely on the old size limitation for sizing their own buffers so removing the limit should have no externally visible effect.

Mac OS X mangles file names containing unicode on file systems HFS+, VFAT or SAMBA. When a file using unicode code points outside ASCII is created on a HFS+ drive, the file name is converted into decomposed unicode and written to disk. No conversion is done if the file name is already decomposed unicode. Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same result as open("\x41\xcc\x88",...) with a decomposed "Ä". As a consequence, readdir() returns the file names in decomposed unicode, even if the user expects precomposed unicode. Unlike on HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in precomposed unicode, but readdir() still returns file names in decomposed unicode. When a git repository is stored on a network share using SAMBA, file names are send over the wire and written to disk on the remote system in precomposed unicode, but Mac OS X readdir() returns decomposed unicode to be compatible with its behaviour on HFS+ and VFAT. The unicode decomposition causes many problems: - The names "git add" and other commands get from the end user may often be precomposed form (the decomposed form is not easily input from the keyboard), but when the commands read from the filesystem to see what it is going to update the index with already is on the filesystem, readdir() will give decomposed form, which is different. - Similarly "git log", "git mv" and all other commands that need to compare pathnames found on the command line (often but not always precomposed form; a command line input resulting from globbing may be in decomposed) with pathnames found in the tree objects (should be precomposed form to be compatible with other systems and for consistency in general). - The same for names stored in the index, which should be precomposed, that may need to be compared with the names read from readdir(). NFS mounted from Linux is fully transparent and does not suffer from the above. As Mac OS X treats precomposed and decomposed file names as equal, we can - wrap readdir() on Mac OS X to return the precomposed form, and - normalize decomposed form given from the command line also to the precomposed form, to ensure that all pathnames used in Git are always in the precomposed form. This behaviour can be requested by setting "core.precomposedunicode" configuration variable to true. The code in compat/precomposed_utf8.c implements basically 4 new functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(), precomposed_utf8_closedir() and precompose_argv(). The first three are to wrap opendir(3), readdir(3), and closedir(3) functions. The argv[] conversion allows to use the TAB filename completion done by the shell on command line. It tolerates other tools which use readdir() to feed decomposed file names into git. When creating a new git repository with "git init" or "git clone", "core.precomposedunicode" will be set "false". The user needs to activate this feature manually. She typically sets core.precomposedunicode to "true" on HFS and VFAT, or file systems mounted via SAMBA.

When calling "git push" without argument, we want to allow Git to do something simple to explain and safe. push.default=matching is unsafe when used to push to shared repositories, and hard to explain to beginners in some contexts. It is debatable whether 'upstream' or 'current' is the safest or the easiest to explain, so introduce a new mode called 'simple' that is the intersection of them: push to the upstream branch, but only if it has the same name remotely. If not, give an error that suggests the right command to push explicitely to 'upstream' or 'current'. A question is whether to allow pushing when no upstream is configured. An argument in favor of allowing the push is that it makes the new mode work in more cases. On the other hand, refusing to push when no upstream is configured encourages the user to set the upstream, which will be beneficial on the next pull. Lacking better argument, we chose to deny the push, because it will be easier to change in the future if someone shows us wrong.

A section in a config file with a missing "]" reports the next line as bad, same goes to a value with a missing end quote. This happens because the error is not detected until the end of the line, when line number is already increased. Fix this by decreasing line number by one for these cases.

It can be useful to split your ~/.gitconfig across multiple files. For example, you might have a "main" file which is used on many machines, but a small set of per-machine tweaks. Or you may want to make some of your config public (e.g., clever aliases) while keeping other data back (e.g., your name or other identifying information). Or you may want to include a number of config options in some subset of your repos without copying and pasting (e.g., you want to reference them from the .git/config of participating repos). This patch introduces an include directive for config files. It looks like: [include] path = /path/to/file This is syntactically backwards-compatible with existing git config parsers (i.e., they will see it as another config entry and ignore it unless you are looking up include.path). The implementation provides a "git_config_include" callback which wraps regular config callbacks. Callers can pass it to git_config_from_file, and it will transparently follow any include directives, passing all of the discovered options to the real callback. Include directives are turned on automatically for "regular" git config parsing. This includes calls to git_config, as well as calls to the "git config" program that do not specify a single file (e.g., using "-f", "--global", etc). They are not turned on in other cases, including: 1. Parsing of other config-like files, like .gitmodules. There isn't a real need, and I'd rather be conservative and avoid unnecessary incompatibility or confusion. 2. Reading single files via "git config". This is for two reasons: a. backwards compatibility with scripts looking at config-like files. b. inspection of a specific file probably means you care about just what's in that file, not a general lookup for "do we have this value anywhere at all". If that is not the case, the caller can always specify "--includes". 3. Writing files via "git config"; we want to treat include.* variables as literal items to be copied (or modified), and not expand them. So "git config --unset-all foo.bar" would operate _only_ on .git/config, not any of its included files (just as it also does not operate on ~/.gitconfig).

This is a magic global variable that was intended as an override to the usual git-config lookup process. Once upon a time, you could specify GIT_CONFIG to any git program, and it would look only at that file. This turned out to be confusing and cause a lot of bugs for little gain. As a result, dc871831 (Only use GIT_CONFIG in "git config", not other programs, 2008-06-30) took this away for all callers except git-config. Since git-config no longer uses it either, the variable can just go away. As the diff shows, nobody was setting to anything except NULL, so we can just replace any sites where it was read with NULL.

Callers may want to provide a specific version of a file in which to look for config. Right now this can be done by setting the magic global config_exclusive_filename variable. By providing a version of git_config that takes a filename, we can take a step towards making this magic global go away. Furthermore, by providing a more "advanced" interface, we now have a a natural place to add new options for callers like git-config, which care about tweaking the specifics of config lookup, without disturbing the large number of "simple" users (i.e., every other part of git). The astute reader of this patch may notice that the logic for handling config_exclusive_filename was taken out of git_config_early, but added into git_config. This means that git_config_early will no longer respect config_exclusive_filename. That's OK, because the only other caller of git_config_early is check_repository_format_gently, but the only function which sets config_exclusive_filename is cmd_config, which does not call check_repository_format_gently (and if it did, it would have been a bug, anyway, as we would be checking the repository format in the wrong file).

The other config-writing functions (git_config_set and git_config_set_multivar) each have an -"in_file" version to write a specific file. Let's add one for rename_section, with the eventual goal of moving away from the magic config_exclusive_filename global.

The git_config_set_multivar_in_file function takes a filename argument to specify the file into which the values should be written. Currently, this value must be non-NULL. Callers which want to write to the default location must use the regular, non-"in_file" version, which will either write to config_exclusive_filename, or to the repo config if the exclusive filename is NULL. Let's migrate the "default to using repo config" logic into the "in_file" form. That will let callers get the same default-if-NULL behavior as one gets with config_exclusive_filename, but without having to use the global variable.

This extends the earlier approach to stream a large file directly from the filesystem to its own packfile, and allows "git add" to send large files directly into a single pack. Older code used to spawn fast-import, but the new bulk-checkin API replaces it. Signed-off-by: NJunio C Hamano <gitster@pobox.com>
