Russell Belfer 373cf6a9 2013-12-09T10:17:47 Update docs for new callback return value behavior
Russell Belfer 96869a4e 2013-12-03T16:45:39 Improve GIT_EUSER handling This adds giterr_user_cancel to return GIT_EUSER and clear any error message that is sitting around. As a result of using that in places, we need to be more thorough with capturing errors that happen inside a callback when used internally. To help with that, this also adds giterr_capture and giterr_restore so that when we internally use a foreach-type function that clears errors and converts them to GIT_EUSER, it is easier to restore not just the return value, but the actual error message text.
Russell Belfer 25e0b157 2013-12-06T15:07:57 Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.

Vicent Marti 1eab9f0e 2013-11-05T14:56:10 error: Simplify giterr_detach
Russell Belfer d6c60169 2013-11-04T15:45:31 Add giterr_detach API to get and clear error There are a number of cases where it is convenient to be able to fetch and "claim" the current error string, clearing the error. This is helpful when you need to call some code that may alter the error and you want to restore it later on and/or report it via some other mechanism.
Russell Belfer 974774c7 2013-09-09T16:57:34 Add attributes to filters and fix registry The filter registry as implemented was too primitive to actually work once multiple filters were coming into play. This expands the implementation of the registry to handle multiple prioritized filters correctly. Additionally, this adds an "attributes" field to a filter that makes it really really easy to implement filters that are based on one or more attribute values. The lookup and even simple value checking can all happen automatically without custom filter code. Lastly, with the registry improvements, this fills out the filter lifecycle callbacks, with initialize and shutdown callbacks that will be called before the filter is first used and after it is last invoked. This allows for system-wide initialization and cleanup by the filter.
Vicent Martí efc9e670 2013-09-17T03:45:35 Merge pull request #1856 from libgit2/cmn/no-orphans No such thing as an orphan branch
Carlos Martín Nieto 605da51a 2013-09-17T09:50:30 No such thing as an orphan branch Unfortunately git-core uses the term "unborn branch" and "orphan branch" interchangeably. However, "orphan" is only really there for the checkout command, which has the `--orphan` option so it doesn't actually create the branch. Branches never have parents, so the distinction of a branch with no parents is odd to begin with. Crucially, the error messages deal with unborn branches, so let's use that.

Carlos Martín Nieto 3d276874 2013-08-19T10:30:44 index: report when it's locked Report the index being locked with its own error code in order to be able to differentiate, as a locked index is typically the result of a crashed process or concurrent access, both of which often require user intervention to fix.

Russell Belfer ad9a921b 2012-11-08T17:05:07 Rework checkout with new strategy options This is a major reworking of checkout strategy options. The checkout code is now sensitive to the contents of the HEAD tree and the new options allow you to update the working tree so that it will match the index content only when it previously matched the contents of the HEAD. This allows you to, for example, to distinguish between removing files that are in the HEAD but not in the index, vs just removing all untracked files. Because of various corner cases that arise, etc., this required some additional capabilities in rmdir and other utility functions. This includes the beginnings of an implementation of code to read a partial tree into the index based on a pathspec, but that is not enabled because of the possibility of creating conflicting index entries.

This makes the `giterr_set_str()` and `giterr_set_oom()` functions public.

Russell Belfer f335ecd6 2012-08-30T14:24:16 Diff iterators This refactors the diff output code so that an iterator object can be used to traverse and generate the diffs, instead of just the `foreach()` style with callbacks. The code has been rearranged so that the two styles can still share most functions. This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses that as a common error code for marking the end of iteration when using a iterator style of object.
Russell Belfer aa13bf05 2012-08-02T13:00:58 Major submodule rewrite This replaces the old submodule API with a new extended API that supports most of the things that can be done with `git submodule`.
Russell Belfer 5dca2010 2012-08-03T17:08:01 Update iterators for consistency across library This updates all the `foreach()` type functions across the library that take callbacks from the user to have a consistent behavior. The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.

Russell Belfer 7c7ff7d1 2012-03-19T16:10:11 Migrate index, oid, and utils to new errors This includes a few cleanups that came up while converting these files. This commit introduces a could new git error classes, including the catchall class: GITERR_INVALID which I'm using as the class for invalid and out of range values which are detected at too low a level of library to use a higher level classification. For example, an overflow error in parsing an integer or a bad letter in parsing an OID string would generate an error in this class.
Russell Belfer e3c47510 2012-03-13T14:23:24 Resolve comments from pull request This converts the map validation function into a macro, tweaks the GITERR_OS system error automatic appending, and adds a tentative new error access API and some quick unit tests for both the old and new error APIs.
Russell Belfer e1de726c 2012-03-12T22:55:40 Migrate ODB files to new error handling This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to the new style of error handling. Also got the unix and win32 versions of map.c. There are some minor changes to other files but no others were completely converted. This also contains an update to filebuf so that a zeroed out filebuf will not think that the fd (== 0) is actually open (and inadvertently call close() on fd 0 if cleaned up). Lastly, this was built and tested on win32 and contains a bunch of fixes for the win32 build which was pretty broken.
Vicent Martí dda708e7 2012-03-09T19:55:50 error-handling: On-disk config file backend Includes: - Proper error reporting when encountering syntax errors in a config file (file, line number, column). - Rewritten `config_write`, now with 99% less goto-spaghetti - Error state in `git_filebuf`: filebuf write functions no longer need to be checked for error returns. If any of the writes performed on a buffer fail, the last call to `git_filebuf_commit` or `git_filebuf_hash` will fail accordingly and set the appropiate error message. Baller!

Vicent Martí cb8a7961 2012-03-07T00:02:55 error-handling: Repository This also includes droping `git_buf_lasterror` because it makes no sense in the new system. Note that in most of the places were it has been dropped, the code needs cleanup. I.e. GIT_ENOMEM is going away, so instead it should return a generic `-1` and obviously not throw anything.
Vicent Martí 1a481123 2012-02-17T00:13:34 error-handling: References Yes, this is error handling solely for `refs.c`, but some of the abstractions leak all ofer the code base.

If the buffer is too short, it returns an error saying so. Adapt the git transport to use this and fix the offset calculation. Add the GIT_ESHORTBUFFER error code.
Carlos Martín Nieto 63f91e1c 2011-06-22T16:52:30 Add git.git's fnmatch, which is really GNU's and the git__fnmatch wrapper If the strings match, git__fnmatch returns GIT_SUCCESS and GIT_ENOMATCH on failure to match. MSVC fixes: Added a test for _MSC_VER and (in that case) defined HAVE_STRING_H to 1 so it doesn't try to include <strings.h> which doesn't exist in the MSVC world. Moved the function declarations to use the modern inline ones so MSVC doesn't have a fit. Added casts everywhere so MSVC doesn't crap its pants. Signed-off-by: Carlos Martín Nieto <carlos@cmartin.tk>
