* git on Mac OS and precomposed unicodeTorsten Bögershausen2012-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* move git_default_* variables to ident.cJeff King2012-05-22
| | | | | | | | | | | | | | There's no reason anybody outside of ident.c should access these directly (they should use the new accessors which make sure the variables are initialized), so we can make them file-scope statics. While we're at it, move user_ident_explicitly_given into ident.c; while still globally visible, it makes more sense to reside with the ident code.

* push: Provide situational hints for non-fast-forward errorsChristopher Tiwald2012-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pushing a non-fast-forward update to a remote repository will result in an error, but the hint text doesn't provide the correct resolution in every case. Give better resolution advice in three push scenarios: 1) If you push your current branch and it triggers a non-fast-forward error, you should merge remote changes with 'git pull' before pushing again. 2) If you push to a shared repository others push to, and your local tracking branches are not kept up to date, the 'matching refs' default will generate non-fast-forward errors on outdated branches. If this is your workflow, the 'matching refs' default is not for you. Consider setting the 'push.default' configuration variable to 'current' or 'upstream' to ensure only your current branch is pushed. 3) If you explicitly specify a ref that is not your current branch or push matching branches with ':', you will generate a non-fast-forward error if any pushed branch tip is out of date. You should checkout the offending branch and merge remote changes before pushing again. Teach transport.c to recognize these scenarios and configure push.c to hint for them. If 'git push's default behavior changes or we discover more scenarios, extension is easy. Standardize on the advice API and add three new advice variables, 'pushNonFFCurrent', 'pushNonFFDefault', and 'pushNonFFMatching'. Setting any of these to 'false' will disable their affiliated advice. Setting 'pushNonFastForward' to false will disable all three, thus preserving the config option for users who already set it, but guaranteeing new users won't disable push advice accidentally.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code calls git_config from a helper function to parse the config entry it is interested in. Calling git_config in this way may cause a problem if the helper function can be called after a previous call to git_config by another function since the second call to git_config may reset some variable to the value in the config file which was previously overridden. The above is not a problem in this case since the function passed to git_config only parses one config entry and the variable it sets is not assigned outside of the parsing function. But a programmer who desires all of the standard config options to be parsed may be tempted to modify git_attr_config() so that it falls back to git_default_config() and then it _would_ be vulnerable to the above described behavior. So, move the call to git_config up into the top-level cmd_* function and move the responsibility for parsing core.attributesfile into the main config file parser. Which is only the logical thing to do ;-) Signed-off-by: Brandon Casey <drafnel@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Git can expose each namespace as an independent repository to pull from and push to, while sharing the object store, and exposing all the refs to operations such as git-gc. Storing multiple repositories as namespaces of a single repository avoids storing duplicate copies of the same objects, such as when storing multiple branches of the same source. The alternates mechanism provides similar support for avoiding duplicates, but alternates do not prevent duplication between new objects added to the repositories without ongoing maintenance, while namespaces do. To specify a namespace, set the GIT_NAMESPACE environment variable to the namespace. For each ref namespace, git stores the corresponding refs in a directory under refs/namespaces/. For example, GIT_NAMESPACE=foo will store refs under refs/namespaces/foo/. You can also specify namespaces via the --namespace option to git. Note that namespaces which include a / will expand to a hierarchy of namespaces; for example, GIT_NAMESPACE=foo/bar will store refs under refs/namespaces/foo/refs/namespaces/bar/. This makes paths in GIT_NAMESPACE behave hierarchically, so that cloning with GIT_NAMESPACE=foo/bar produces the same result as cloning with GIT_NAMESPACE=foo and cloning from that repo with GIT_NAMESPACE=bar. It also avoids ambiguity with strange namespace paths such as foo/refs/heads/, which could otherwise generate directory/file conflicts within the refs directory. Add the infrastructure for ref namespaces: handle the GIT_NAMESPACE environment variable and --namespace option, and support iterating over refs in a namespace.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a repository without object replacement, lookup_replace_object() should be a no-op. Check the flag "read_replace_refs" on the side of the caller, and bypess a function call when we know we are not dealing with replacement. Also, even when we are set up to replace objects, if we do not find any replacement defined, flip that flag off to avoid function call overhead for all the later object accesses. As this change the semantics of the flag from "do we need read the replacement definition?" to "do we need to check with the lookup table?" the flag needs to be renamed later to something saner, e.g. "use_replace", when the codebase is calmer, but not now.

* | convert: rename the "eol" global variable to "core_eol"Junio C Hamano2011-05-09
|/ | | | | | | | | | | | | Yes, it is clear that "eol" wants to mean some sort of end-of-line thing, but as the name of a global variable, it is way too short to describe what kind of end-of-line thing it wants to represent. Besides, there are many codepaths that want to use their own local "char *eol" variable to point at the end of the current line they are processing.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default of 7 comes from fairly early in git development, when seven hex digits was a lot (it covers about 250+ million hash values). Back then I thought that 65k revisions was a lot (it was what we were about to hit in BK), and each revision tends to be about 5-10 new objects or so, so a million objects was a big number. These days, the kernel isn't even the largest git project, and even the kernel has about 220k revisions (_much_ bigger than the BK tree ever was) and we are approaching two million objects. At that point, seven hex digits is still unique for a lot of them, but when we're talking about just two orders of magnitude difference between number of objects and the hash size, there _will_ be collisions in truncated hash values. It's no longer even close to unrealistic - it happens all the time. We should both increase the default abbrev that was unrealistically small, _and_ add a way for people to set their own default per-project in the git config file. This is the first step to first make it configurable; the default of 7 is not raised yet. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | If setup_git_env() is run before the usual repository discovery sequence and .git is a file with the text gitdir: <path> (with <path> any string) then the in-core git_dir variable is set to the result of converting <path> to an absolute path using make_absolute_path(). Unfortunately make_absolute_path() returns its result in a static buffer that is overwritten by later calls. Such a call could cause later accesses to git_dir (from git_pathdup(), for example) to read the wrong path, leaving git very confused. It is not obvious whether any existing code in git will trigger the problem, but in any case, it is worth a few dozen bytes to copy the return value from make_absolute_path() for some added peace of mind.

* | git wrapper: introduce startup_info structNguyễn Thái Ngọc Duy2010-08-11
|/ | | | | | | | | | | | | | | | | | | | The startup_info struct will collect information managed by the git setup code, such as the prefix for relative paths passed on the command line (i.e., path to the starting cwd from the toplevel of the work tree) and whether a git repository has been found. In other words, startup_info is intended to be a collection of global variables with results that were previously returned from setup functions. This state is global anyway (since the cwd is), even if it is not currently tracked that way. Letting these values persist means there is more flexibility in deciding when to run setup. For now, the struct is empty.

| * Add "core.eol" config variableEyvind Bernhardsen2010-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new configuration variable, "core.eol", that allows the user to set which line endings to use for end-of-line-normalized files in the working directory. It defaults to "native", which means CRLF on Windows and LF everywhere else. Note that "core.autocrlf" overrides core.eol. This means that [core] autocrlf = true puts CRLFs in the working directory even if core.eol is set to "lf".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the semantics of the "crlf" attribute so that it enables end-of-line normalization when it is set, regardless of "core.autocrlf". Add a new setting for "crlf": "auto", which enables end-of-line conversion but does not override the automatic text file detection. Add a new attribute "eol" with possible values "crlf" and "lf". When set, this attribute enables normalization and forces git to use CRLF or LF line endings in the working directory, respectively. The line ending style to be used for normalized text files in the working directory is set using "core.autocrlf". When it is set to "true", CRLFs are used in the working directory; when set to "input" or "false", LFs are used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This has the same effect as --no-replace-objects option; git ignores the replace refs. When --no-replace-objects option is passed to git, this environment variable is set to "1" and exported to subprocesses in order to propagate the same setting. It is useful for example for scripts, as the git commands used in them can now be aware that they must not read replace refs.
