2007-04-18Fix funny types used in attribute value representationJunio C Hamano
It was bothering me a lot that I abused small integer values casted to (void *) to represent non string values in gitattributes. This corrects it by making the type of attribute values (const char *), and using the address of a few statically allocated character buffer to denote true/false. Unset attributes are represented as having NULLs as their values. Added in-header documentation to explain how git_checkattr() routine should be called. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-18Allow low-level driver to specify different behaviour during internal merge.Junio C Hamano
This allows [merge "drivername"] to have a variable "recursive" that names a different low-level merge driver to be used when merging common ancestors to come up with a virtual ancestor. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-18Custom low-level merge driver: change the configuration scheme.Junio C Hamano
This changes the configuration syntax for defining a low-level merge driver to be: [merge "<<drivername>>"] driver = "<<command line>>" name = "<<driver description>>" which is much nicer to read and is extensible. Credit goes to Martin Waitz and Linus. In addition, when we use an external low-level merge driver, it is reported as an extra output from merge-recursive, using the value of merge.<<drivername>.name variable. The demonstration in t6026 has also been updated. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-18Allow the default low-level merge driver to be configured.Junio C Hamano
When no 'merge' attribute is given to a path, merge-recursive uses the built-in xdl-merge as the low-level merge driver. A new configuration item 'merge.default' can name a low-level merge driver of user's choice to be used instead. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-18Custom low-level merge driver support.Junio C Hamano
This allows users to specify custom low-level merge driver per path, using the attributes mechanism. Just like you can specify one of built-in "text", "binary", "union" low-level merge drivers by saying: * merge=text .gitignore merge=union *.jpg merge=binary pick a name of your favorite merge driver, and assign it as the value of the 'merge' attribute. A custom low-level merge driver is defined via the config mechanism. This patch introduces 'merge.driver', a multi-valued configuration. Its value is the name (i.e. the one you use as the value of 'merge' attribute) followed by a command line specification. The command line can contain %O, %A, and %B to be interpolated with the names of temporary files that hold the common ancestor version, the version from your branch, and the version from the other branch, and the resulting command is spawned. The low-level merge driver is expected to update the temporary file for your branch (i.e. %A) with the result and exit with status 0 for a clean merge, and non-zero status for a conflicted merge. A new test in t6026 demonstrates a sample usage. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-17Add a demonstration/test of customized merge.Junio C Hamano
This demonstrates how the new low-level per-path merge backends, union and ours, work, and shows how they are controlled by the gitattribute mechanism. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-17Allow specifying specialized merge-backend per path.Junio C Hamano
This allows 'merge' attribute to control how the file-level three-way merge is done per path. - If you set 'merge' to true, leave it unspecified, or set it to "text", we use the built-in 3-way xdl-merge. - If you set 'merge' to false, or set it to "binary, the "binary" merge is done. The merge result is the blob from 'our' tree, but this still leaves the path conflicted, so that the mess can be sorted out by the user. This is obviously meant to be useful for binary files. - 'merge=union' (this is the first example of a string valued attribute, introduced in the previous one) uses the "union" merge. The "union" merge takes lines in conflicted hunks from both sides, which is useful for line-oriented files such as .gitignore. Instead fo setting merge to 'true' or 'false' by using 'merge' or '-merge', setting it explicitly to "text" or "binary" will become useful once we start allowing custom per-path backends to be added, and allow them to be activated for the default (i.e. 'merge' attribute specified to 'true' or 'false') case, using some other mechanisms. Setting merge attribute to "text" or "binary" will be a way to explicitly request to override such a custom default for selected paths. Currently there is no way to specify random programs but it should be trivial for motivated contributors to add later. There is one caveat, though. ll_merge() is called for both internal ancestor merge and the outer "final" merge. I think an interactive custom per-path merge backend should refrain from going interactive when performing an internal merge (you can tell it by checking call_depth) and instead just call either ll_xdl_merge() if the content is text, or call ll_binary_merge() otherwise.

2007-04-17Allow more than true/false to attributes.Junio C Hamano
This allows you to define three values (and possibly more) to each attribute: true, false, and unset. Typically the handlers that notice and act on attribute values treat "unset" attribute to mean "do your default thing" (e.g. crlf that is unset would trigger "guess from contents"), so being able to override a setting to an unset state is actually useful. - If you want to set the attribute value to true, have an entry in .gitattributes file that mentions the attribute name; e.g. *.o binary - If you want to set the attribute value explicitly to false, use '-'; e.g. *.a -diff - If you want to make the attribute value _unset_, perhaps to override an earlier entry, use '!'; e.g. *.a -diff c.i.a !diff This also allows string values to attributes, with the natural syntax: attrname=attrvalue but you cannot use it, as nobody takes notice and acts on it yet.

2007-04-15Define a built-in attribute macro "binary".Junio C Hamano
For binary files we would want to disable textual diff generation and automatic crlf conversion. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-15attribute macro supportJunio C Hamano
This adds "attribute macros" (for lack of better name). So far, we have low-level attributes such as crlf and diff, which are defined in operational terms --- setting or unsetting them on a particular path directly affects what is done to the path. For example, in order to decline diffs or crlf conversions on a binary blob, no diffs on PostScript files, and treat all other files normally, you would have something like these: * diff crlf *.ps !diff proprietary.o !diff !crlf That is fine as the operation goes, but gets unwieldy rather rapidly, when we start adding more low-level attributes that are defined in operational terms. A near-term example of such an attribute would be 'merge-3way' which would control if git should attempt the usual 3-way file-level merge internally, or leave merging to a specialized external program of user's choice. When it is added, we do _not_ want to force the users to update the above to: * diff crlf merge-3way *.ps !diff proprietary.o !diff !crlf !merge-3way The way this patch solves this issue is to realize that the attributes the user is assigning to paths are not defined in terms of operations but in terms of what they are. All of the three low-level attributes usually make sense for most of the files that sane SCM users have git operate on (these files are typically called "text'). Only a few cases, such as binary blob, need exception to decline the "usual treatment given to text files" -- and people mark them as "binary". So this allows the $GIT_DIR/info/alternates and .gitattributes at the toplevel of the project to also specify attributes that assigns other attributes. The syntax is '[attr]' followed by an attribute name followed by a list of attribute names: [attr] binary !diff !crlf !merge-3way When "binary" attribute is set to a path, if the path has not got diff/crlf/merge-3way attribute set or unset by other rules, this rule unsets the three low-level attributes. It is expected that the user level .gitattributes will be expressed mostly in terms of attributes based on what the files are, and the above sample would become like this: (built-in attribute configuration) [attr] binary !diff !crlf !merge-3way * diff crlf merge-3way (project specific .gitattributes) proprietary.o binary (user preference $GIT_DIR/info/attributes) *.ps !diff There are a few caveats. * As described above, you can define these macros only in $GIT_DIR/info/attributes and toplevel .gitattributes. * There is no attempt to detect circular definition of macro attributes, and definitions are evaluated from bottom to top as usual to fill in other attributes that have not yet got values. The following would work as expected: [attr] text diff crlf [attr] ps text !diff *.ps ps while this would most likely not (I haven't tried): [attr] ps text !diff [attr] text diff crlf *.ps ps * When a macro says "[attr] A B !C", saying that a path does not have attribute A does not let you tell anything about attributes B or C. That is, given this: [attr] text diff crlf [attr] ps text !diff *.txt !ps path hello.txt, which would match "*.txt" pattern, would have "ps" attribute set to zero, but that does not make text attribute of hello.txt set to false (nor diff attribute set to true).

2007-04-15Fix 'diff' attribute semantics.Junio C Hamano
This is in the same spirit as the previous one. Earlier 'diff' meant 'do the built-in binary heuristics and disable patch text generation based on it' while '!diff' meant 'do not guess, do not generate patch text'. There was no way to say 'do generate patch text even when the heuristics says it has NUL in it'. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-15Fix 'crlf' attribute semantics.Junio C Hamano
Earlier we said 'crlf lets the path go through core.autocrlf process while !crlf disables it altogether'. This fixes the semantics to: - Lack of 'crlf' attribute makes core.autocrlf to apply (i.e. we guess based on the contents and if platform expresses its desire to have CRLF line endings via core.autocrlf, we do so). - Setting 'crlf' attribute to true forces CRLF line endings in working tree files, even if blob does not look like text (e.g. contains NUL or other bytes we consider binary). - Setting 'crlf' attribute to false disables conversion.

2007-04-14Define 'crlf' attribute.Junio C Hamano
This defines the semantics of 'crlf' attribute as an example. When a path has this attribute unset (i.e. '!crlf'), autocrlf line-end conversion is not applied. Eventually we would want to let users to build a pipeline of processing to munge blob data to filesystem format (and in the other direction) based on combination of attributes, and at that point the mechanism in convert_to_{git,working_tree}() that looks at 'crlf' attribute needs to be enhanced. Perhaps the existing 'crlf' would become the first step in the input chain, and the last step in the output chain. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-14Add basic infrastructure to assign attributes to pathsJunio C Hamano
This adds the basic infrastructure to assign attributes to paths, in a way similar to what the exclusion mechanism does based on $GIT_DIR/info/exclude and .gitignore files. An attribute is just a simple string that does not contain any whitespace. They can be specified in $GIT_DIR/info/attributes file, and .gitattributes file in each directory. Each line in these files defines a pattern matching rule. Similar to the exclusion mechanism, a later match overrides an earlier match in the same file, and entries from .gitattributes file in the same directory takes precedence over the ones from parent directories. Lines in $GIT_DIR/info/attributes file are used as the lowest precedence default rules. A line is either a comment (an empty line, or a line that begins with a '#'), or a rule, which is a whitespace separated list of tokens. The first token on the line is a shell glob pattern. The rest are names of attributes, each of which can optionally be prefixed with '!'. Such a line means "if a path matches this glob, this attribute is set (or unset -- if the attribute name is prefixed with '!'). For glob matching, the same "if the pattern does not have a slash in it, the basename of the path is matched with fnmatch(3) against the pattern, otherwise, the path is matched with the pattern with FNM_PATHNAME" rule as the exclusion mechanism is used. This does not define what an attribute means. Tying an attribute to various effects it has on git operation for paths that have it will be specified separately.
