2021-05-05checkout-index: add parallel checkout supportMatheus Tavares
Allow checkout-index to use the parallel checkout framework, honoring the checkout.workers configuration. There are two code paths in checkout-index which call `checkout_entry()`, and thus, can make use of parallel checkout: `checkout_file()`, which is used to write paths explicitly given at the command line; and `checkout_all()`, which is used to write all paths in the index, when the `--all` option is given. In both operation modes, checkout-index doesn't abort immediately on a `checkout_entry()` failure. Instead, it tries to check out all remaining paths before exiting with a non-zero exit code. To keep this behavior when parallel checkout is being used, we must allow `run_parallel_checkout()` to try writing the queued entries before we exit, even if we already got an error code from a previous `checkout_entry()` call. However, `checkout_all()` doesn't return on errors, it calls `exit()` with code 128. We could make it call `run_parallel_checkout()` before exiting, but it makes the code easier to follow if we unify the exit path for both checkout-index modes at `cmd_checkout_index()`, and let this function take care of the interactions with the parallel checkout API. So let's do that. With this change, we also have to consider whether we want to keep using 128 as the error code for `git checkout-index --all`, while we use 1 for `git checkout-index <path>` (even when the actual error is the same). Since there is not much value in having code 128 only for `--all`, and there is no mention about it in the docs (so it's unlikely that changing it will break any existing script), let's make both modes exit with code 1 on `checkout_entry()` errors.

The declarations of entry.c's public functions and structures currently reside in cache.h.

2021-02-16checkout-index: omit entries with no tempname from --temp outputMatheus Tavares
With --temp (or --stage=all, which implies --temp), checkout-index writes a list to stdout associating temporary file names to the entries' names. But if it fails to write an entry, and the failure happens before even assigning a temporary filename to that entry, we get an odd output line. This can be seen when trying to check out a symlink whose blob is missing: $ missing_blob=$(git hash-object --stdin </dev/null) $ git update-index --add --cacheinfo 120000,$missing_blob,foo $ git checkout-index --temp foo error: unable to read sha1 file of foo (e69de29bb2d1d6434b8b29ae775ad8c2e48c5391) foo The 'TAB foo' line is not much useful and it might break scripts that expect the 'tempname TAB foo' output. So let's omit such entries from the stdout list (but leaving the error message on stderr). We could also consider omitting _all_ failed entries from the output list, but that's probably not a good idea as the associated tempfiles may have been created even when checkout failed, so scripts may want to use the output list for cleanup.

2020-10-27checkout-index: propagate errors to exit codeJeff King
If we encounter an error while checking out an explicit path, we print a message to stderr but do not actually exit with a non-zero code. While this is a plumbing command and the behavior goes all the way back to 33db5f4d90 (Add a "checkout-cache" command which does what the name suggests., 2005-04-09), this is almost certainly an oversight: - we _do_ return an exit code from checkout_file(); the caller just never reads it - errors while checking out all paths (with "-a") do result in a non-zero exit code. - it would be quite unusual not to use the exit code for an error, as otherwise the caller has no idea the command failed except by scraping stderr To keep our tests simple and portable, we can use the most obvious error: asking to checkout a path which is not in the index at all.

2020-10-27checkout-index: drop error message from empty --stage=allJeff King
If checkout-index is given --stage=all for a specific path, it will try to write stages 1-3 (if present) for that path to temporary files. However, if the file is present only at stage 0, it writes nothing but gives a confusing message: $ git checkout-index --stage=all -- Makefile git checkout-index: Makefile does not exist at stage 4 This is nonsense. There is no stage 4 (it's just an internal enum value we use for "all"), and the documentation clearly states: Paths which only have a stage 0 entry will always be omitted from the output. Here it's talking about the list of tempfiles written to stdout, but it seems clear that this case was not meant to be an error. We even have a test which covers it, but it only checks that the command reports an exit code of 0, not its stderr. And it reports 0 only because of another bug which fails to propagate errors (which will be fixed in a subsequent patch). So let's make the test more thorough. We'll also cover the case that we found _no_ entry, not even a stage zero, which should still be an error. However, because of the other bug, we'll have to mark this as expecting failure for the moment. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-04-28Use OPT_CALLBACK and OPT_CALLBACK_FDenton Liu
In the codebase, there are many options which use OPTION_CALLBACK in a plain ol' struct definition. However, we have the OPT_CALLBACK and OPT_CALLBACK_F macros which are meant to abstract these plain struct definitions away. These macros are useful as they semantically signal to developers that these are just normal callback option with nothing fancy happening. Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or OPT_CALLBACK_F where applicable. The heavy lifting was done using the following (disgusting) shell script: #!/bin/sh do_replacement () { tr '\n' '\r' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\s*0,\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK(\1,\2,\3,\4,\5,\6)/g' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK_F(\1,\2,\3,\4,\5,\6,\7)/g' | tr '\r' '\n' } for f in $(git ls-files \*.c) do do_replacement <"$f" >"$f.tmp" mv "$f.tmp" "$f" done The result was manually inspected and then reformatted to match the style of the surrounding code. Finally, using `git grep OPTION_CALLBACK \*.c`, leftover results which were not handled by the script were manually transformed.

2018-11-14checkout: print something when checking out pathsNguyễn Thái Ngọc Duy
One of the problems with "git checkout" is that it does so many different things and could confuse people specially when we fail to handle ambiguation correctly. One way to help with that is tell the user what sort of operation is actually carried out. When switching branches, we always print something unless --quiet, either - "HEAD is now at ..." - "Reset branch ..." - "Already on ..." - "Switched to and reset ..." - "Switched to a new branch ..." - "Switched to branch ..." Checking out paths however is silent. Print something so that if we got the user intention wrong, they won't waste too much time to find that out. For the remaining cases of checkout we now print either - "Checked out ... paths out of the index" - "Checked out ... paths out of <abbrev hash>" Since the purpose of printing this is to help disambiguate. Only do it when "--" is missing. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-11-06assert NOARG/NONEG behavior of parse-options callbacksJeff King
When we define a parse-options callback, the flags we put in the option struct must match what the callback expects. For example, a callback which does not handle the "unset" parameter should only be used with PARSE_OPT_NONEG. But since the callback and the option struct are not defined next to each other, it's easy to get this wrong (as earlier patches in this series show). Fortunately, the compiler can help us here: compiling with -Wunused-parameters can show us which callbacks ignore their "unset" parameters (and likewise, ones that ignore "arg" expect to be triggered with PARSE_OPT_NOARG). But after we've inspected a callback and determined that all of its callers use the right flags, what do we do next? We'd like to silence the compiler warning, but do so in a way that will catch any wrong calls in the future. We can do that by actually checking those variables and asserting that they match our expectations. Because this is such a common pattern, we'll introduce some helper macros. The resulting messages aren't as descriptive as we could make them, but the file/line information from BUG() is enough to identify the problem (and anyway, the point is that these should never be seen). Each of the annotated callbacks in this patch triggers -Wunused-parameters, and was manually inspected to make sure all callers use the correct options (so none of these BUGs should be triggerable).

2017-10-06checkout-index: simplify locking logicMartin Ågren
`newfd` starts out negative. If we then take the lock, `newfd` will become non-negative. We later check for exactly that property before calling `write_locked_index()`. That is, we are simply using `newfd` as a boolean to keep track of whether we took the lock or not. (We always use `newfd` and `lock_file` together, so they really are mirroring each other.) Drop `newfd` and check with `is_lock_file_locked()` instead. While at it, move the `static struct lock_file` into `cmd_checkout_index()` and make it non-static. It is only used in this function, and after 076aa2cbd (tempfile: auto-allocate tempfiles on heap, 2017-09-05), we can have lockfiles on the stack.

2016-12-07hold_locked_index(): align error handling with hold_lockfile_for_update()Junio C Hamano
Callers of the hold_locked_index() function pass 0 when they want to prepare to write a new version of the index file without wishing to die or emit an error message when the request fails (e.g. somebody else already held the lock), and pass 1 when they want the call to die upon failure. This option is called LOCK_DIE_ON_ERROR by the underlying lockfile API, and the hold_locked_index() function translates the paramter to LOCK_DIE_ON_ERROR when calling the hold_lock_file_for_update(). Replace these hardcoded '1' with LOCK_DIE_ON_ERROR and stop translating. Callers other than the ones that are replaced with this change pass '0' to the function; no behaviour change is intended with this patch. Signed-off-by: Junio C Hamano <gitster@pobox.com> --- Among the callers of hold_locked_index() that passes 0: - diff.c::refresh_index_quietly() at the end of "git diff" is an opportunistic update; it leaks the lockfile structure but it is just before the program exits and nobody should care. - builtin/describe.c::cmd_describe(), builtin/commit.c::cmd_status(), sequencer.c::read_and_refresh_cache() are all opportunistic updates and they are OK. - builtin/update-index.c::cmd_update_index() takes a lock upfront but we may end up not needing to update the index (i.e. the entries may be fully up-to-date), in which case we do not need to issue an error upon failure to acquire the lock. We do diagnose and die if we indeed need to update, so it is OK. - wt-status.c::require_clean_work_tree() IS BUGGY. It asks silence, does not check the returned value. Compare with callsites like cmd_describe() and cmd_status() to notice that it is wrong to call update_index_if_able() unconditionally.

2016-02-01checkout-index: disallow "--no-stage" optionJeff King
We do not really expect people to use "--no-stage", but if they do, git currently segfaults. We could instead have it undo the effects of a previous "--stage", but this gets tricky around the "to_tempfile" flag. We cannot simply reset it to 0, because we don't know if it was set by a previous "--stage=all" or an explicit "--temp" option. We could solve this by setting a flag and resolving to_tempfile later, but it's not worth the effort. Nobody actually wants to use "--no-stage"; we are just trying to fix a potential segfault here. While we're in the area, let's improve the user-facing messages for this option.

2016-02-01checkout-index: handle "--no-index" optionJeff King
The parsing of "--index" is done in a callback, but it does not handle an "unset" option. We don't necessarily expect anyone to use this, but the current behavior is to treat it exactly like "--index", which would probably be surprising. Instead, let's just turn it into an OPT_BOOL, and handle it after we're done parsing. This makes "--no-index" just work (it cancels a previous "--index"). As a bonus, this makes the logic easier to follow. The old code opened the index during the option parsing, leaving the reader to wonder if there was some timing issue (there isn't; none of the other options care that we've opened it). And then if we found that "--prefix" had been given, we had to rollback the index. Now we can simply avoid opening it in the first place. Note that it might make more sense for checkout-index to complain when "--index --prefix=foo" is given (rather than silently ignoring "--index"), but since it has been that way since 415e96c ([PATCH] Implement git-checkout-cache -u to update stat information in the cache., 2005-05-15), it's safer to leave it as-is.

2014-12-29checkout-index: fix --temp relative path manglingEric Sunshine
checkout-index --temp only properly prints relative paths which are descendants of the current directory. Paths in ancestor or sibling directories (or their children) are often printed in mangled form. For example: mkdir a bbb && >file && >bbb/file && git update-index --add file bbb/file && cd a && git checkout-index --temp ../file ../bbb/file prints: .merge_file_ooblek le .merge_file_igloo0 b/file rather than the correct: .merge_file_ooblek ../file .merge_file_igloo0 ../bbb/file Internally, given the above example, checkout-index prefixes each input argument with the name of the current directory ("a/", in this case), and then assumes that it can simply skip forward by strlen("a/") bytes to recover the original name. This works for files in the current directory or its descendants, but fails for files in ancestors or siblings (or their children) due to path normalization. For instance, given "../file", "a/" is prepended, giving "a/../file". Path normalization folds out "a/../", resulting in "file". Attempting to recover the original name by skipping strlen("a/") bytes gives the incorrect "le" rather than the desired "../file". Fix this by taking advantage of write_name_quoted_relative() to recover the original name properly, rather than assuming that it can be recovered by skipping strlen(prefix) bytes. As a bonus, this also fixes a bug in which checkout-index --temp accessed and printed memory beyond the end-of-string. For instance, within a subdirectory named "subdirectory", and given argument "../file", prefixing would give "subdirectory/../file", which would become "file" after normalization. checkout-index would then attempt to recover the original name by skipping strlen("subdirectory/") bytes of "file", which placed it well beyond end-of-string. Despite this error, it often appeared to give the correct result, but only due to an accident of implementation which left an apparently correct copy of the path in memory following the normalized value. In particular, handed "subdirectory/../file", in-place processing by normalize_path_copy_len() resulted in "file\0rectory/../file". When checkout-index skipped strlen("subdirectory/") bytes, it ended up back at "../file" and thus appeared to give the correct answer, despite being past end-of-string.

The said function has this signature: extern int checkout_entry(struct cache_entry *ce, const struct checkout *state, char *topath); At first glance, it might appear that the caller of checkout_entry() can specify to which path the contents are written out by the last parameter, and it is tempting to add "const" in front of its type. In reality, however, topath[] is to point at a buffer to store the temporary path generated by the callchain originating from this function, and the temporary path is always short, much shorter than the buffer prepared by its only caller in builtin/checkout-index.c.

Since b04ba2bb (parse-options: deprecate OPT_BOOLEAN, 2011-09-27) the OPT_BOOLEAN is deprecated and is only a define: /* Deprecated synonym */ #define OPTION_BOOLEAN OPTION_COUNTUP However the variable not_new, which can be counted up by giving --no-create multiple times, is used to set a bit in the struct checkout bitfield (defined in cache.h:969, declared at builtin/checkout-index.c:19): state.not_new = not_new; When assigning a value other than 0 or 1 to a bit, all leading digits but the last are ignored and only the last bit is used for setting the bit variable. Hence the following: # in git.git: $ git status # working directory clean rm COPYING $ git status # deleted: COPYING $ git checkout-index -a -n $ git status # deleted: COPYING # which is expected as we're telling git to not restore or create # files, however: $ git checkout-index -a -n -n $ git status # working directory clean, COPYING is restored again! # That's the bug, we're fixing here. By restraining the variable not_new to a value being definitely 0 or 1 by the macro OPT_BOOL the bug is fixed.

2013-08-05Replace deprecated OPT_BOOLEAN by OPT_BOOLStefan Beller
This task emerged from b04ba2bb (parse-options: deprecate OPT_BOOLEAN, 2011-09-27). All occurrences of the respective variables have been reviewed and none of them relied on the counting up mechanism, but all of them were using the variable as a true boolean. This patch does not change semantics of any command intentionally. Signed-off-by: Stefan Beller <stefanbeller@googlemail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-10-22checkout-index -h: show usage even in an invalid repositoryNguyễn Thái Ngọc Duy
checkout-index loads the index before parsing options. Erroring out is counterproductive at that point if the operator is hunting for a command to recover useful data from the broken repository.

2010-02-22Move 'builtin-*' into a 'builtin/' subdirectoryLinus Torvalds
This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities? (y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
