Stefan Sperling fe621944 2020-11-10T22:54:37 merge new diff implementation from the git.gameoftrees.org diff.git repository This new diff implementation was started by Neels Hofmeyr during the u2k20 hackathon and now replaces diffreg.c code lifted from the OpenBSD base system. The integration of this code into Got was done by me. Got now uses the patience diff algorithm by default. The diff.git repository will remain the primary repository for the diff code, which already compiles and runs on other operating systems such as Linux. Any fixes and improvements for files inherited from the diff.git repository should be written against that repository and synced to got.git afterwards.
Stefan Sperling f6d8c0ac 2020-11-09T16:04:18 fix replacing symlinks with files And add a test case which verifies that the inverse also works, i.e. a symlink being replaced with a regular file. problem reported and fix tested by jrick
Stefan Sperling 63df146d 2020-11-09T16:03:35 fix missing unlink(tmppath) in error cases of install_blob()

Stefan Sperling 727173c3 2020-11-06T00:20:05 initialize sb.st_mode after stat(2) failure in got_worktree_resolve_path()
Stefan Sperling 01740607 2020-11-04T20:18:53 avoid got_repo_map_path() in 'got blame' 'got blame' does not need access to the work tree. So far the work tree was completely hidden with unveil(). We must now expose the work tree while resolving the path, so unveil() calls are shuffled around slightly. Failing realpath() calls would mess with path resolution otherwise. There's a bug in got_worktree_resolve_path() where it failed to canonicalize a path constructed from a user-specified path that does not exist on disk. Note that this path falls into strncmp() a few lines down. I am fixing this by adding canonicalization. Generally, joining paths with asprintf() and comparing paths with strncmp() is fragile. A more general solution might be needed but I am leaving that for another day. ok naddy

Stefan Sperling 0a22ca1a 2020-09-23T22:31:00 make 'got histedit' collapse folded add+delete operations into a no-op If a merged commit wants to delete a locally added file, and this locally added file matches the content which was deleted in the commit being merged, we can go ahead with the deletion because there is no risk of data loss. fixes the histedit problem reported by jrick on freenode
Stefan Sperling 50b0790e 2020-09-11T17:04:57 add per-worktree got.conf(5) file in the .got directory; ok millert
Christian Weisgerber 0823ffc2 2020-09-10T20:44:40 use modern POSIX timestamp fields in struct stat ok stsp
Stefan Sperling 766841c2 2020-08-13T19:12:57 add -s option to 'got remove' which deletes files in a particular status This makes it easy to deal with files that were deleted from disk by external tooling which modified the work tree. Such files are left in missing (!) status and can now be marked for deletion in bulk via 'got rm -s\! -R .' For consistency, modified (M) files can now be removed with 'got rm -s M' which implies 'got rm -f'. Prompted by feedback from krw@
Stefan Sperling f2b0a8b0 2020-07-31T12:54:34 fix committing file additions from a work tree with a path prefix New files were added under the wrong tree in the repository if the work tree has a path prefix. Fix this problem and catch it in the existing commit_with_path_prefix regression test.
Stefan Sperling 69d57f3d 2020-07-31T11:19:29 fix spurious 'got cherrypick' error with a path prefix and an empty tree If the work tree's path prefix does not exist in the first of the two trees, then 'got cherrypick' failed with "no such entry found in tree". But this is a legitimate situation, as shown in the new test added here. The first tree could be the empty tree, for example, which should result in 'got cherrypick' adding all files from the second tree instead of complaining about a non-existent path-prefix directory in the first tree.
Stefan Sperling b66cd6f3 2020-07-31T10:33:34 display more context info in "no such entry found in tree" error messages
Stefan Sperling b2118c49 2020-07-28T20:17:19 Add a 'got info' command which displays work tree meta-data. Remove the alias 'got in' for 'got init'. The 'in' alias was too close to either 'init' or 'info'. ok tracey, millert
Stefan Sperling 283102fc 2020-07-23T14:22:41 remove the symlink conflict header feature; it causes noise for little benefit

Stefan Sperling b7422a2f 2020-07-23T14:22:38 stop using realpath(3) to resolve a symlink target in install_symlink() We should not resolve a symlink target path recursively when installing a symlink in the work tree. We want to handle this symlink's target, not the end result of following a chain of symlinks in case such links already exist.

Stefan Sperling 65b05cec 2020-07-23T14:22:35 add an output argument to create_fileindex_entry() Avoids a pointless search of the file index in the case the caller needs to use the newly created file entry.

Stefan Sperling 054041d0 2020-06-24T17:15:00 replace the update_blob_fileindex_entry() helper function This makes it easier to tell in which code paths we are expecting to handle a potential 'ie' NULL pointer and avoids a pointless search of the file index.
Stefan Sperling 5a58a424 2020-06-23T16:10:01 plug a memory leak in delete_blob()

Stefan Sperling ba580f68 2020-03-22T15:08:33 prevent 'got commit' from comitting empty sub-directories; found by tracey
Stefan Sperling 3969253a 2020-03-07T19:01:44 remove implicit entry update from got_fileindex_entry_alloc(); just alloc
Tracey Emery 15341bfd 2020-03-05T14:39:37 trim directories in got remove -R This is a racy solution that needs to be properly implemented in the future. ok stsp
Stefan Sperling de05890f 2020-03-05T10:53:53 fix histedit 'rebase commit ID mismatch' error when splitting a commit Commit IDs on histedit's temporary branch can change arbitrarily because the user may create new commits on this branch while editing past commits. So there is no point in trying to verify these IDs like we do during rebase. Add a test case which demonstrates the problem.
Stefan Sperling 63f810e6 2020-02-29T07:54:55 when "bad path" errors occur, always show the path in question

Stefan Sperling 6201aef3 2020-02-02T09:20:56 ignore EROFS during checkout for repositories on read-only filesystems
Stefan Sperling a46b9f33 2020-01-28T12:09:03 fix a bug where 'got revert -R' failed on added subtrees The command could fail with "got: no such entry found in tree". This problem is reproduced by the regression test added in this commit. This happened because file index entries were processed in the wrong order by diff_fileindex_dir(). To fix this, keep removed entries in the RB tree and skip them when the file index is written out, rather than removing entries from the RB tree immediately causing side-effects for RB_NEXT and friends.
Stefan Sperling 867630bb 2020-01-17T11:54:27 Sleep for one nanosecond after syncing the file index to disk Ensures that files modified after got exits have a different timestamp from the one which was recorded in the file index. Previously, 'got status' did not always detect such files as modified. Problem reported by Steven McDonald.
