Nothing appears to benefit from this being non-static, and it was missing from the public API headers as well. ok stsp@

When users run 'got add *' the shell may pick up already versioned files and trigger errors about paths being in an unexpected status. Expand the check which previously only allowed files in added status to be double-added to cover the following status codes which are all safe to ignore: A M C m This should make bulk additions of files a bit easier in most cases.

Split part of got_worktree_merge_prepare into a new function, got_worktree_merge_write_refs, since that part doesn't make sense in the fast-forward case. ok stsp@

Otherwise, 'got merge -c' can silently revert already committed changes. Also fix GOT_ERR_MERGE_COMMIT_OUT_OF_DATE by giving it a value distinct from GOT_ERR_MERGE_STAGED_PATHS. Patch by James Cook

Make 'got rm' keep empty directories which are not explicitly listed for deletion. Deleting such directories is problematic in several use cases. Avoids deleting the current working directory when the user runs "got rm *" (pointed out by Mikhail), and avoids deletion of an empty directory "foo/" after 'got rm foo/a foo/b' (pointed out by op@). ok jamsek, op

Problem reported by James Cook with reproduction scripts Regression test case by jamsek, as a simplified version of James' scripts fix tested + ok jamsek

Otherwise we leave unversioned files behind in the work tree which may interfere with new attempts to rebase or merge the changes again. Problem found by + ok naddy@

problem found by robert@ ok jamsek, op

The commands 'got rebase -a' and 'got histedit -a' were checking out files from the wrong commit. Make them check files out from the commit we are switching the work tree to, as intended. Avoids spurious merge conflicts when the work tree is later used for another rebase operation. It also makes 'got update' right after 'rebase -a' a no-op, as it should be. Problem found by naddy@ while rebasing jca's llvm15 branch ok op, jamsek earlier version

This avoids having to run 'got update' after operations which run checkout_files() and where a file happens to have the same blob ID but its base commit differs from the commit we are updating to. Found while investigating a bug report by naddy@ ok op, jamsek (earlier version)

Rather than assume all dependencies are required for all programs, split them out. This will make packaging easier, as well as splitting the code to use subprojects. Note that due to the use of config.h semantics, in most cases the got_compat.h header file is now at the top of the .c file it is included in, so that it can handle the system header inclusion properly.

Simply the SHA detection by not predicating on libcrypto, but instead checking individual header files.

Remove sha1.h as this is found portably across systems.

It will soon grow functions to deal with sha256 too. stsp@ agrees.

In preparation for wide sha256 support; stsp@ agrees. Change done mechanically with find . -iname \*.[cy] -exec sam {} + X ,x/<sha1\.h>/i/\n#include <sha2.h>

To skip chunks without newly added lines. ok stsp@

ok jamsek

Rather than skip lines, use the new diff APIs to directly seek to each chunk with newly added lines for more efficient conflict marker detection. ok stsp@

As per stsp's original design for detecting new conflicts, rather than produce a diff formatted for human consumption, parse the raw diff result to scan only newly added lines for conflict markers. While here, fix a couple related bugs in the original implementation: (1) rewind the versioned file blob so we don't end up with an empty "from" (i.e., LHS of the diff) file; and (2) force an ASCII text diff for so we don't miss conflicts in binary files. ok stsp@
