| * use strbuf_addstr() for adding constant strings to a strbuf, part 2René Scharfe2016-09-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace uses of strbuf_addf() for adding strings with more lightweight strbuf_addstr() calls. This makes the intent clearer and avoids potential issues with printf format specifiers. 02962d36845b89145cd69f8bc65e015d78ae3434 already converted six cases, this patch covers eleven more. A semantic patch for Coccinelle is included for easier checking for new cases that might be introduced in the future.

|\ | | | | | | | | | | | | | | | | | | | | | | | | When "git merge-recursive" works on history with many criss-cross merges in "verbose" mode, the names the command assigns to the virtual merge bases could have overwritten each other by unintended reuse of the same piece of memory. * rs/pull-signed-tag: commit: use FLEX_ARRAY in struct merge_remote_desc merge-recursive: fix verbose output for multiple base trees commit: factor out set_merge_remote_desc() commit: use xstrdup() in get_merge_parent()
| * merge-recursive: fix verbose output for multiple base treesRené Scharfe2016-08-131-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the indirect callers of make_virtual_commit() passes the result of oid_to_hex() as the name, i.e. a pointer to a static buffer. Since the function uses that string pointer directly in building a struct merge_remote_desc, multiple entries can end up sharing the same name inadvertently. Fix that by calling set_merge_remote_desc(), which creates a copy of the string, instead of building the struct by hand.

* | merge-recursive: flush output buffer even when erroring outjs/am-3-merge-recursive-directJohannes Schindelin2016-08-011-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ever since 66a155b (Enable output buffering in merge-recursive., 2007-01-14), we had a problem: When the merge failed in a fatal way, all regular output was swallowed because we called die() and did not get a chance to drain the output buffers. To fix this, several modifications were necessary: - we needed to stop die()ing, to give callers a chance to do something when an error occurred (in this case, flush the output buffers), - we needed to delay printing the error message so that the caller can print the buffered output before that, and - we needed to make sure that the output buffers are flushed even when the return value indicates an error. The first two changes were introduced through earlier commits in this patch series, and this commit addresses the third one.

* | merge_trees(): ensure that the callers release output bufferJohannes Schindelin2016-08-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recursive merge machinery accumulates its output in an output buffer, to be flushed at the end of merge_recursive(). At this point, we forgot to release the output buffer. When calling merge_trees() (i.e. the non-recursive part of the recursive merge) directly, the output buffer is never flushed because the caller may be merge_recursive() which wants to flush the output itself. For the same reason, merge_trees() cannot release the output buffer: it may still be needed. Forgetting to release the output buffer did not matter much when running git-checkout, or git-merge-recursive, because we exited after the operation anyway. Ever since cherry-pick learned to pick a commit range, however, this memory leak had the potential of becoming a problem.

* | merge-recursive: offer an option to retain the output in 'obuf'Johannes Schindelin2016-08-011-4/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 66a155b (Enable output buffering in merge-recursive., 2007-01-14), we already accumulate the output in a buffer. The idea was to avoid interfering with the progress output that goes to stderr, which is unbuffered, when we write to stdout, which is buffered. We extend that buffering to allow the caller to handle the output (possibly suppressing it). This will help us when extending the sequencer to do rebase -i's brunt work: it does not want the picks to print anything by default but instead determine itself whether to print the output or not. Note that we also redirect the error messages into the output buffer when the caller asked not to flush the output buffer, for two reasons: 1) to retain the correct output order, and 2) to allow the caller to suppress *all* output.

* | merge-recursive: write the commit title in one goJohannes Schindelin2016-08-011-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 66a155b (Enable output buffering in merge-recursive., 2007-01-14), we changed the code such that it prints the output in one go, to avoid interfering with the progress output. Let's make sure that the same holds true when outputting the commit title: previously, we used several printf() statements to stdout and assumed that stdout's buffer is large enough to hold the entire commit title. Apart from making that speculation unnecessary, we change the code to add the message to the output buffer before flushing for another reason: the next commit will introduce a new level of output buffering, where the caller can request the output not to be flushed, but to be retained for further processing. This latter feature will be needed when teaching the sequencer to do rebase -i's brunt work: it wants to control the output of the cherry-picks (i.e. recursive merges).

* | merge-recursive: flush output buffer before printing error messagesJohannes Schindelin2016-08-011-48/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The data structure passed to the recursive merge machinery has a feature where the caller can ask for the output to be buffered into a strbuf, by setting the field 'buffer_output'. Previously, we died without flushing, losing accumulated output. With this patch, we show the output first, and only then print the error message. Currently, the only user of that buffering is merge_recursive() itself, to avoid the progress output to interfere. In the next patches, we will introduce a new buffer_output mode that forces merge_recursive() to retain the output buffer for further processing by the caller. If the caller asked for that, we will then also write the error messages into the output buffer. This is necessary to give the caller more control not only how to react in case of errors but also control how/if to display the error messages.

* | merge-recursive: switch to returning errors instead of dyingJohannes Schindelin2016-07-261-27/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The recursive merge machinery is supposed to be a library function, i.e. it should return an error when it fails. Originally the functions were part of the builtin "merge-recursive", though, where it was simpler to call die() and be done with error handling. The existing callers were already prepared to detect negative return values to indicate errors and to behave as previously: exit with code 128 (which is the same thing that die() does, after printing the message).

* | merge-recursive: handle return values indicating errorsJohannes Schindelin2016-07-261-102/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are about to libify the recursive merge machinery, where we only die() in case of a bug or memory contention. To that end, we must heed negative return values as indicating errors. This requires our functions to be careful to pass through error conditions in call chains, and for quite a few functions this means that they have to return values to begin with. The next step will be to convert the places where we currently die() to return negative values (read: -1) instead. Note that we ignore errors reported by make_room_for_path(), consistent with the previous behavior (update_file_flags() used the return value of make_room_for_path() only to indicate an early return, but not a fatal error): if the error is really a fatal error, we will notice later; If not, it was not that serious a problem to begin with. (Witnesses in favor of this reasoning are t4151-am-abort and t7610-mergetool, which would start failing if we stopped on errors reported by make_room_for_path()). Also note: while this patch makes the code slightly less readable in update_file_flags() (we introduce a new "goto free_buf;" instead of an explicit "free(buf); return;"), it is a preparatory change for the next patch where we will convert all of the die() calls in the same function to go through the free_buf return path instead.

* | merge-recursive: avoid returning a wholesale structJohannes Schindelin2016-07-261-50/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is technically allowed, as per C89, for functions' return type to be complete structs (i.e. *not* just pointers to structs). However, it was just an oversight of this developer when converting Python code to C code in 6d297f8 (Status update on merge-recursive in C, 2006-07-08) which introduced such a return type. Besides, by converting this construct to pass in the struct, we can now start returning a value that can indicate errors in future patches. This will help the current effort to libify merge-recursive.c. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | merge_recursive: abort properly upon errorsJohannes Schindelin2016-07-261-5/+12
| | | | | | | | | | | | | | | | | | | | | | There are a couple of places where return values never indicated errors before, as we simply died instead of returning.

* | merge-recursive: clarify code in was_tracked()Johannes Schindelin2016-07-261-16/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It can be puzzling to see that was_tracked() asks to get an index entry by name, but does not take a negative return value for an answer. The reason we have to do this is that cache_name_pos() only looks for entries in stage 0, even if nobody asked for any stage in particular. Let's rewrite the logic a little bit, to handle the easy case early: if cache_name_pos() returned a non-negative position, we know it is a match, and we do not even have to compare the name again (cache_name_pos() did that for us already). We can say right away: yes, this file was tracked. Only if there was no exact match do we need to look harder for any matching entry in stage 2.

* | die(_("BUG")): avoid translating bug messagesJohannes Schindelin2016-07-261-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While working on the patch series that avoids die()ing in recursive merges, the issue came up that bug reports (i.e. die("BUG: ...") constructs) should never be translated, as the target audience is the Git developer community, not necessarily the current user, and hence a translated message would make it *harder* to address the problem. So let's stop translating the obvious ones. As it is really, really outside the purview of this patch series to see whether there are more die() statements that report bugs and are currently translated, that task is left for another day and patch.

The add_cacheinfo() function in turn calls make_cache_entry() to create a new cache entry to replace the higher-stage entries for the path that represents the conflict. The make_cache_entry() function calls refresh_cache_entry() to fill in the cached stat information. To mark a cache entry as up-to-date, the data is re-read from the file in the working tree, and goes through convert_to_git() conversion to be compared with the blob object name the new cache entry records. It is important to note that this happens while the higher-stage entries, which are going to be replaced with the new entry, are still in the index. Unfortunately, the convert_to_git() conversion has a misguided "safer crlf" mechanism baked in, and looks at the existing cache entry for the path to decide how to convert the contents in the working tree file. If our side (i.e. stage#2) records a text blob with CRLF in it, even when the system is configured to record LF in blobs and convert them to CRLF upon checkout (and back to LF upon checkin), the "safer crlf" mechanism stops us doing so. This especially poses a problem during a renormalizing merge, where the merge result for the path is computed by first "normalizing" the blobs involved in the merge by using convert_to_working_tree() followed by convert_to_git() with "safer crlf" disabled. The merge result that is computed correctly and fed to add_cacheinfo() via update_file_flags() does _not_ match what refresh_cache_entry() sees by converting the working tree file via convert_to_git(). We can work this around by not refreshing the new cache entry in make_cache_entry() called by add_cacheinfo(). After add_cacheinfo() adds the new entry, we can call refresh_cache_entry() on that, knowing that addition of this new cache entry would have removed the stale cache entries that had CRLF in stage #2 that were carried over before the renormalizing merge started and will not interfere with the correct recording of the result. The test update was taken from a series by Torsten Bögershausen that attempted to fix this with a different approach.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were a few cases in merge-recursive that could result in a check for the presence of files in the working copy while trying to create a virtual merge base. These were rare and innocuous, but somewhat illogical. The two cases were: * When there was naming conflicts (e.g. a D/F conflict) and we had to pick a new unique name for a file. Since the new name is somewhat arbitrary, it didn't matter that we consulted the working copy to avoid picking a filename it has, but since the virtual merge base is never checked out, it's a waste of time and slightly odd to do so. * When two different files get renamed to the same name (on opposite sides of the merge), we needed to delete the original filenames from the cache and possibly also the working directory. The caller's check for determining whether to delete from the working directory was a call to would_lose_untracked(). It turns out this didn't matter because remove_file() had logic to avoid modifying the working directory when creating a virtual merge base, but there is no reason for the caller to check the working directory in such circumstances. It's a waste of time, if not also a bit weird. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | Convert most instances where the sha1 member of struct object is dereferenced to use get_object_hash. Most instances that are passed to functions that have versions taking struct object_id, such as get_sha1_hex/get_oid_hex, or instances that can be trivially converted to use struct object_id instead, are not converted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If one side deletes a file and the other changes its content, we notice and report a conflict. However, if instead of changing the content, we change only the mode, the merge does not notice (and the mode change is silently dropped). The trivial index merge notices the problem and correctly leaves the conflict in the index, but both merge-recursive and merge-one-file will silently resolve this in favor of the deletion. In many cases that is a sane resolution, but we should be punting to the user whenever there is any question. So let's detect and treat this as a conflict (in both strategies).

* | merge-recursive: convert malloc / strcpy to strbufJeff King2015-10-051-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This would be a fairly routine use of xstrfmt, except that we need to remember the length of the result to pass to cache_name_pos. So just use a strbuf, which makes this simple. As a bonus, this gets rid of confusing references to "pathlen+1". The "1" is for the trailing slash we added, but that is automatically accounted for in the strbuf's len parameter.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The callers of get_merge_bases() can choose to leave object flags used during the merge-base traversal by passing cleanup=0 as a parameter, but in practice a very few callers can afford to do so (namely, "git merge-base"), as they need to compute merge base in preparation for other processing of their own and they need to see the object without contaminate flags. Change the function signature of get_merge_bases_many() and get_merge_bases() to drop the cleanup parameter, so that the majority of the callers do not have to say ", 1" at the end. Give a new get_merge_bases_many_dirty() API to support only a few callers that know they do not need to spend cycles cleaning up the object flags. Signed-off-by: Junio C Hamano <gitster@pobox.com>
