record: allow splitting of hunks by manually editing patches It is possible that unrelated changes in a file are on sequential lines. The current record extension does not allow these to be committed independently. An example use case for this is in software development for deeply embedded real-time systems. In these environments, it is not always possible to use a debugger (due to time-constraints) and hence inline UART-based printing is often used. When fixing a bug in a module, it is often convenient to add a large number of 'printf's (linked to the UART via a custom fputc) to the module in order to work out what is going wrong. printf is a very slow function (and also variadic so somewhat frowned upon by the MISRA standard) and hence it is highly undesirable to commit these lines to the repository. If only a partial fix is implemented, however, it is desirable to commit the fix without deleting all of the printf lines. This is also simplifies removal of the printf lines as once the final fix is committed, 'hg revert' does the rest. It is likely that the printf lines will be very near the actual fix, so being able to split the hunk is very useful in this case. There were two alternatives I considered for the user interface. One was to manually edit the patch, the other to allow a hunk to be split into individual lines for consideration. The latter option would require a significant refactor of the record module and is less flexible. While the former is potentially more complicated to use, this is a feature that is likely to only be used in certain exceptional cases (such as the use case proposed above) and hence I felt that the complexity would not be a considerable issue. I've also written a follow-up patch that refactors the 'prompt' code to base everything on the choices variable. This tidies up and clarifies the code a bit (removes constructs like 'if ret == 7' and removes the 'e' option from the file scope options as it's not relevant there. It's not really a necessity, so I've excluded it from this submission for now, but I can send it separately if there's a desire and it's on bitbucket (see below) in the meantime. Possible future improvements include: * Tidying up the 'prompt' code to base everything on the choices variable. This would allow entries to be removed from the prompt as currently 'e' is offered even for entire file patches, which is currently unsupported. * Allowing the entire file (or even multi-file) patch to be edited manually: this would require quite a large refactor without much benefit, so I decided to exclude it from the initial submission. * Allow the option to retry if a patch fails to apply (this is what Git does). This would require quite a bit of refactoring given the current 'hg record' implementation, so it's debatable whether it's worth it. Output is similar to existing record user interface except that an additional option ('e') exists to allow manual editing of the patch. This opens the user's configured editor with the patch. A comment is added to the bottom of the patch explaining what to do (based on Git's one). A large proportion of the changeset is test-case changes to update the options reported by record (Ynesfdaq? instead of Ynsfdaq?). Functional changes are in record.py and there are some new test cases in test-record.t. [ original upstream message ]

mq: restore _branchtags() fast path (issue3223) Since a5917346c72e, mq saves the nodeid of the first applied patch to cache/branchheads, which breaks the optimized cache handling introduced in fbf8320f25c8. The problem is the revision being committed is appended to mqrepo.applied after the commit succeeds, which means mqrepo._branchtags() performs a regular update and write the first applied patch to the branch cache. One solution is to set a context variable _committingpatch on the mqrepo while it is committing a patch and to take it in account when deciding to fast-path mqrepo._branchtags(). Not really elegant but it works. The changes to test-mq-caches.t reverse changes introduced by a5917346c72e. The cache should not have been updated with mq records. The changes to test-keyword.t are indirectly caused by a5917346c72e. Reported and analyzed by Yuya Nishihara <yuya@tcha.org> Notes: - qpush still makes a slow path _branchtags() call when checking heads. Maybe this can be optimized. - be careful when merging this patch in default as secretcommit() was renamed newcommit() right after the end of the code freeze. [ original upstream message ]

tests: tighten checks for octal escapes in shell printf. printf on AIX default shell ksh (89) says \1 is an invalid escape. It insists on at least 2 digits.

run-tests: replace inline python handling with more native scheme Normally changes in tests are reported like this in diffs: $ cat foo - a + b Using -i mode lets us update tests when the new results are correct and/or populate tests with their output.

rollback: avoid unsafe rollback when not at tip (issue2998) You can get into trouble if you commit, update back to an older changeset, and then rollback. The update removes your valuable changes from the working dir, then rollback removes them history. Oops: you've just irretrievably lost data running nothing but core Mercurial commands. (More subtly: rollback from a shared clone that was already at an older changeset -- no update required, just rollback from the wrong directory.) The fix assumes that only "commit" transactions have irreplaceable data, and allows rolling back non-commit transactions as always. But when rolling back a commit, check that the working dir is checked out to tip, i.e. the changeset we're about to destroy. If not, abort. You can get back the old (dangerous) behaviour with --force. [ original upstream message ]

run-tests: end doctest block when seeing a non-command [ original upstream message ]

tests: add support for inline doctests in test files This adds doctest like syntax to .t files, that can be interleaved with regular shell code: $ echo -n a > file >>> print open('file').read() a >>> open('file', 'a').write('b') $ cat file ab The syntax is exactly the same as regular doctests, so multiline statements look like this: >>> for i in range(3): ... print i 0 1 2 Each block has its own context, i.e.: >>> x = 0 >>> print x 0 $ echo 'foo' foo >>> print x will result in a NameError. Errors are displayed in standard doctest format: >>> print 'foo' bar --- /home/idan/dev/hg/default/tests/test-test.t +++ /home/idan/dev/hg/default/tests/test-test.t.err @@ -2,3 +2,16 @@ > >>> print 'foo' > bar > EOF + ********************************************************************** + File "/tmp/tmps8X_0ohg-tst", line 1, in tmps8X_0ohg-tst + Failed example: + print 'foo' + Expected: + bar + Got: + foo + ********************************************************************** + 1 items had failures: + 1 of 1 in tmps8X_0ohg-tst + ***Test Failed*** 1 failures. + [1] As for the implementation, it's quite simple: when the test runner sees a line starting with '>>>' it converts it, and all subsequent lines until the next line that begins with '$' to a 'python -m heredoctest <<EOF' call with the proper heredoc to follow. So if we have this test file: >>> for c in 'abcd': ... print c a b c d $ echo foo foo It gets converted to: $ python -m heredoctest <<EOF > >>> for c in 'abcd': > ... print c > a > b > c > d > EOF $ echo foo foo And then processed like every other test file by converting it to a sh script.

import: wrap a transaction around the whole command Now 'rollback' after 'import' is less surprising: it rolls back all of the imported changesets, not just the last one. As an extra added benefit, you don't need 'rollback -f' after 'import --bypass', which was an undesired side effect of fixing issue2998 (59e8bc22506e).. Note that this is a different take on issue963, which complained that rollback after importing multiple patches returned the working dir parent to the starting point, not to the second-last patch applied. Since we now rollback the entire import, returning the working dir to the starting point is entirely logical. So this change also undoes a732eebf1958, the fix to issue963, and updates its tests accordingly. Bottom line: rollback after import was weird before issue963, understandable since the fix for issue963, and even better now. [ original upstream message ]

patch: generalize the use of patchmeta in applydiff() - Add patchmeta.copy() and emit copies from iterhunks. Modifying patchmeta instances in applydiff() makes things simpler. - Rename selectfile() into makepatchmeta(). It is responsible for creating patchmeta for regular patches. - Pass patchmeta objects to patchfile() directly patchmeta instances were associated with git patches, for regular patches we had to pass additional variables to tell the patch intent to patchfile(). Instead, we generate patchmeta for regular patches and pass them. This will also help with patch filtering by matcher objects. [ original upstream message ]

run-tests: allow whitelisting tests that should always run It's desirable to run some tests all the time, for example test-check-pyflakes.t and test-check-code-hg.py. This allows passing --whitelist as a path to a file (flag can be specified more than once) which contains a list of files to whitelist. Whitelisted tests are run even if they're blacklisted or wouldn't match a --keyword test run. For example, to do a quick test of usehttp2, one can now do $ cat > test-whitelist <<EOF > test-check-pyflakes.t > test-check-code-hg.py > EOF $ (cd tests && ./run-tests.py --extra-config-opt 'ui.usehttp2=true' > -k http -j 8 --whitelist test-whitelist) and have all http-specific tests run as well as the two code linters.

patch: use temporary files to handle intermediate copies git patches may require copies to be handled out-of-order. For instance, take the following sequence: * modify a * copy a into b Here, we have to generate b from a before its modification. To do so, applydiff() was scanning for copy metadata and performing the copies before processing the other changes in-order. While smart and efficient, this approach complicates things by handling file copies and file creations at different places and times. While a new file must not exist before being patched a copied file already exists before applying the first hunk. Instead of copying the files at their final destination before patching, we store them in a temporary file location and retrieve them when patching. The filestore always stores file content in real files but nothing prevents adding a cache layer. The filestore class was kept separate from fsbackend for at least two reasons: - This class is likely to be reused as a temporary result store for a future repository patching call (entries just have to be extended to contain copy sources). - Delegating this role to backends might be more efficient in a repository backend case: the source files are already available in the repository itself and do not need to be copied again. It also means that third-parties backend would have to implement two other methods. If we ever decide to merge the filestore feature into backend, a minimalistic approach would be to compose with filestore directly. Keep in mind this copy overhead only applies for copy/rename sources, and may even be reduced to copy sources which have to handled ahead of time. [ original upstream message ]

patch: refactor file creation/removal detection The patcher has to know if a file is being created or removed to check if the target already exists, or to actually unlink the file when a hunk emptying it is applied. This was done by embedding the creation/removal information in the first (and only) hunk attached to the file. There are two problems with this approach: - creation/removal is really a property of the file being patched and not its hunk. - for regular patches, file creation cannot be deduced at parsing time: there are case where the *stripped* file paths must be compared. Modifying hunks after their creation is clumsy and prevent further refactorings related to copies handling. Instead, we delegate this job to selectfile() which has all the relevant information, and remove the hunk createfile() and rmfile() methods. [ original upstream message ]

patch: extract fs access from patchfile into fsbackend Most filesystem calls are already isolated in patchfile but this is not enough: renames are performed before patchfile is available and some chmod calls are even done outside of the applydiff call.
