Ensure return value from xread() is always stored into an ssize_t

2007-05-16T04:16:03Z

This patch fixes all calls to xread() where the return value is not stored into an ssize_t. The patch should not have any effect whatsoever, other than putting better/more appropriate type names on variables. Signed-off-by: Johan Herland Signed-off-by: Junio C Hamano

diff.c: do not use a separate "size cache".

2007-05-07T22:54:32Z

diff_filespec has a slot to record the size of the data already, so make use of it instead of a separate size cache. Signed-off-by: Junio C Hamano

diff: release blobs after generating textual diff.

2007-05-07T22:54:32Z

This reduces the memory pressure when dealing with many paths. An unscientific test of running "diff-tree --stat --summary -M" between v2.6.19 and v2.6.20-rc1 in the linux kernel repository indicates that the number of minor faults are reduced by 2/3. Signed-off-by: Junio C Hamano

diff.c: fix "size cache" handling.

We broke the size-cache handling when we changed the function signature of sha1_object_info() in 21666f1a. We obviously wanted to cache the size we obtained when sha1_object_info() succeeded, not when it failed. Signed-off-by: Junio C Hamano

Support 'diff=pgm' attribute

2007-04-23T05:16:14Z

This enhances the attributes mechanism so that external programs meant for existing GIT_EXTERNAL_DIFF interface can be specifed per path. To configure such a custom diff driver, first define a custom diff driver in the configuration: [diff "my-c-diff"] command = <> Then mark the paths that you want to use this custom driver using the attribute mechanism. *.c diff=my-c-diff The intent of this separation is that the attribute mechanism is used for specifying the type of the contents, while the configuration mechanism is used to define what needs to be done to that type of the contents, which would be specific to both platform and personal taste.

Fix funny types used in attribute value representation

2007-04-18T23:17:13Z

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

Allow more than true/false to attributes.

2007-04-17T08:04:59Z

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.
