Carlos Martín Nieto 5367ec4b 2014-02-05T12:02:52 refs: add an unconditional delete Add it under the git_reference_remove() name, letting the user pass the repo and name, analogous to unconditional setting/creation.

Carlos Martín Nieto 0b28217b 2014-01-15T12:51:31 refs: remove the _with_log differentiation Any well-behaved program should write a descriptive message to the reflog whenever it updates a reference. Let's make this more prominent by removing the version without the reflog parameters.

Russell Belfer 26c1cb91 2013-12-09T09:44:03 One more rename/cleanup for callback err functions
Russell Belfer f10d7a36 2013-12-06T15:53:26 Further callback error check style fixes Okay, I've decided I like the readability of this style much better so I used it everywhere.
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.
Russell Belfer dab89f9b 2013-12-04T21:22:57 Further EUSER and error propagation fixes This continues auditing all the places where GIT_EUSER is being returned and making sure to clear any existing error using the new giterr_user_cancel helper. As a result, places that relied on intercepting GIT_EUSER but having the old error preserved also needed to be cleaned up to correctly stash and then retrieve the actual error. Additionally, as I encountered places where error codes were not being propagated correctly, I tried to fix them up. A number of those fixes are included in the this commit as well.
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.
Carlos Martín Nieto f2105129 2013-11-23T14:39:53 refs: expose has_log() on the backend The frontend used to look at the file directly, but that's obviously not the right thing to do. Expose it on the backend and use that function instead.
Carlos Martín Nieto 8d5ec910 2013-11-23T14:13:01 refs: expose a way to ensure a ref has a log Sometimes (e.g. stash) we want to make sure that a log will be written, even if it's not in one of the standard locations. Let's make that easier.
Carlos Martín Nieto a57dd3b7 2013-11-13T18:15:20 reflog: integrate into the ref writing Whenever a reference is created or updated, we need to write to the reflog regardless of whether the user gave us a message, so we shouldn't leave that to the ref frontend, but integrate it into the backend. This also eliminates the race between ref update and writing to the reflog, as we protect the reflog with the ref lock. As an additional benefit, this reflog append on the backend happens by appending to the file instead of parsing and rewriting it.
Carlos Martín Nieto 110df893 2013-11-13T13:36:37 refdb: add a `message` parameter for appending to the log This is as yet unused.

Vicent Marti 0bfa7323 2013-11-01T17:07:44 iconv: Do not fake an API when iconv is not available
Ben Straub 8f4a8b09 2013-10-28T06:20:28 Merge pull request #1802 from libgit2/cmn/reflog-backend Make reflog part of refdb
Russell Belfer 74353137 2013-10-09T11:57:03 After iconv init reset ref normalize error The iconv init was accidentally clearing the default error state during reference normalization. This resets so that normalization errors will be detected correctly.
Russell Belfer 92dac975 2013-10-08T16:35:57 Make reference lookups apply precomposeunicode Before these changes, looking up a reference would return the same precomposed or decomposed form of the reference name that was used to look it up, so on MacOS which ignores the difference between the two, a single reference could be looked up either way and git_reference_name would return the form of the name that was used to look it up! This change makes lookup always return the precomposed name if core.precomposeunicode is set regardless of which version was used to look it up. The reference iterator was already returning the precomposed form from earlier work. This also updates the CMakeLists.txt rules for enabling iconv usage because the clar tests for this code were actually not being activated properly with the old version. Finally, this moves git_repository_reset_filesystem from include/ git2/repository.h to include/git2/sys/repository.h since it is not really a function that normal library users should have to think about very often.
Carlos Martín Nieto b976f3c2 2013-08-19T13:01:49 reflog: move the reflog implementation into refdb_fs References and their logs are logically coupled, let's make it so in the code by moving the fs-based reflog implementation to live next to the fs-based refs one. As part of the change, make the function take names rather than references, as only the names are relevant when looking up and handling reflogs.

Nikolai Vladimirov 504850cd 2013-08-25T15:59:50 refs: add git_reference_is_tag
Russell Belfer 24c71f14 2013-08-21T14:10:27 Add internal ref set_name fn instead of realloc The refdb_fs implementation calls realloc directly on a reference object when it wants to rename it. It is not a public object, so this doesn't mess with the immutability of references, but it does assume certain constraints on the reference representation. This commit wraps that assumption in an isolated API to isolate it.
Russell Belfer 114f5a6c 2013-06-10T10:10:39 Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.

Carlos Martín Nieto 2b562c3a 2013-05-04T16:32:58 refs: remove the OID/SYMBOLIC filtering Nobody should ever be using anything other than ALL at this level, so remove the option altogether. As part of this, git_reference_foreach_glob is now implemented in the frontend using an iterator. Backends will later regain the ability of doing the glob filtering in the backend.

Russell Belfer 4dcd8780 2013-04-19T17:17:44 Move refdb_backend to include/git2/sys This moves most of the refdb stuff over to the include/git2/sys directory, with some minor shifts in function organization. While I was making the necessary updates, I also removed the trailing whitespace in a few files that I modified just because I was there and it was bugging me.

Carlos Martín Nieto bb45c57f 2013-03-07T16:38:44 refs: explicitly catch leading slashes It's somewhat common to try to write "/refs/tags/something". There is no easy way to catch it during the main body of the function, as there is no way to distinguish whether it's a leading slash or a double slash somewhere in the middle. Catch this at the beginning so we don't trigger the assert in is_all_caps_and_underscore().
Russell Belfer 0d1b094b 2013-02-26T13:15:06 Fix portability issues on Windows The new tests were not taking core.filemode into account when testing file modes after repo initialization. Fixed that and some other Windows warnings that have crept in.
nulltoken c1b5e8c4 2013-02-15T11:35:33 branch: Make git_branch_remote_name() cope with orphaned heads
Russell Belfer 56543a60 2013-02-15T16:02:45 Clear up warnings from cppcheck The cppcheck static analyzer generates warnings for a bunch of places in the libgit2 code base. All the ones fixed in this commit are actually false positives, but I've reorganized the code to hopefully make it easier for static analysis tools to correctly understand the structure. I wouldn't do this if I felt like it was making the code harder to read or worse for humans, but in this case, these fixes don't seem too bad and will hopefully make it easier for better analysis tools to get at any real issues.

Carlos Martín Nieto e5ef0f18 2013-01-31T20:23:30 refs: handle ALLOW_ONELEVEL normalization with leading slash A leading slash confuses the name normalization code when the flags include ALLOW_ONELEVEL. Catch this case in particular to avoid triggering an assertion in the uppercase check which expects us not to pass it an empty string. The existing tests don't catch this as they simply use the NORMAL flag. This fixes #1300.

Scott J. Goldman ef82ff30 2013-01-05T00:46:39 Handle packed refs with no trailing newline I saw a repo in the wild today which had a master branch ref which was packed, but had no trailing newline. Git handled it fine, but libgit2 choked on it. Fix seems simple enough. If we don't see a newline, assume the end of the buffer is the end of the ref line.
Russell Belfer 3865f7f6 2012-12-27T23:23:12 Invalid ref name normalization leaked memory When normalizing a reference name, if there is an error because the name is invalid, then the memory allocated for storing the name could be leaked if the caller was not careful and assumed that the error return code meant that no allocation had occurred. This fixes that by explicitly deallocating the reference name buffer if there is an error in normalizing the name.

Russell Belfer 744cc03e 2012-10-30T12:10:36 Add git_config_refresh() API to reload config This adds a new API that allows users to reload the config if the file has changed on disk. A new config callback function to refresh the config was added. The modified time and file size are used to test if the file needs to be reloaded (and are now stored in the disk backend object). In writing tests, just using mtime was a problem / race, so I wanted to check file size as well. To support that, I extended `git_futils_readbuffer_updated` to optionally check file size in addition to mtime, and I added a new function `git_filebuf_stats` to fetch the mtime and size for an open filebuf (so that the config could be easily refreshed after a write). Lastly, I moved some similar file checking code for attributes into filebuf. It is still only being used for attrs, but it seems potentially reusable, so I thought I'd move it over.

Carlos Martín Nieto 47f44b6e 2012-10-15T13:51:25 refs: loosen the OID parsing We used to require loose references to contain only an OID (possibly after trimming the string). This is however not enough for letting us lookup FETCH_HEAD, which can have a lot of content after the initial OID. Change the parsing rules so that a loose refernce must e at least 40 bytes long and the 41st (if it's there) must be accepted by isspace(3). This makes the trim unnecessary, so only do it for symrefs. This fixes #977.
nulltoken 3548fcf5 2012-10-11T14:00:26 refs: propagate EEXISTS upon renaming
Russell Belfer 0d64bef9 2012-10-05T15:56:57 Add complex checkout test and then fix checkout This started as a complex new test for checkout going through the "typechanges" test repository, but that revealed numerous issues with checkout, including: * complete failure with submodules * failure to create blobs with exec bits * problems when replacing a tree with a blob because the tree "example/" sorts after the blob "example" so the delete was being processed after the single file blob was created This fixes most of those problems and includes a number of other minor changes that made it easier to do that, including improving the TYPECHANGE support in diff/status, etc.
