Merge branch 'jc/object-names-are-not-sha-1'

2020-08-19T23:14:52Z

A few end-user facing messages have been updated to be hash-algorithm agnostic. * jc/object-names-are-not-sha-1: messages: avoid SHA-1 in end-user facing messages

messages: avoid SHA-1 in end-user facing messages

2020-08-14T16:33:37Z

There are still a handful mentions of SHA-1 when we meant the (hexadecimal) object names in end-user facing messages. Rewrite them. I was hoping that this can mostly be s/SHA-1/object name/, but a few messages needed rephrasing to keep the result readable. Signed-off-by: Junio C Hamano

Merge branch 'jt/has_object'

2020-08-13T21:13:39Z

A new helper function has_object() has been introduced to make it easier to mark object existence checks that do and don't want to trigger lazy fetches, and a few such checks are converted using it. * jt/has_object: fsck: do not lazy fetch known non-promisor object pack-objects: no fetch when allow-{any,promisor} apply: do not lazy fetch when applying binary sha1-file: introduce no-lazy-fetch has_object()

Merge branch 'jk/strvec'

2020-08-10T17:23:57Z

The argv_array API is useful for not just managing argv but any "vector" (NULL-terminated array) of strings, and has seen adoption to a certain degree. It has been renamed to "strvec" to reduce the barrier to adoption. * jk/strvec: strvec: rename struct fields strvec: drop argv_array compatibility layer strvec: update documention to avoid argv_array strvec: fix indentation in renamed calls strvec: convert remaining callers away from argv_array name strvec: convert more callers away from argv_array name strvec: convert builtin/ callers away from argv_array name quote: rename sq_dequote_to_argv_array to mention strvec strvec: rename files from argv-array to strvec argv-array: rename to strvec argv-array: use size_t for count and alloc

pack-objects: no fetch when allow-{any,promisor}

2020-08-06T20:01:03Z

The options --missing=allow-{any,promisor} were introduced in caf3827e2f ("rev-list: add list-objects filtering support", 2017-11-22) with the following note in the commit message: This patch introduces handling of missing objects to help debugging and development of the "partial clone" mechanism, and once the mechanism is implemented, for a power user to perform operations that are missing-object aware without incurring the cost of checking if a missing link is expected. The idea that these options are missing-object aware (and thus do not need to lazily fetch objects, unlike unaware commands that assume that all objects are present) are assumed in later commits such as 07ef3c6604 ("fetch test: use more robust test for filtered objects", 2020-01-15). However, the current implementations of these options use has_object_file(), which indeed lazily fetches missing objects. Teach these implementations not to do so. Also, update the documentation of these options to be clearer. Signed-off-by: Jonathan Tan Signed-off-by: Junio C Hamano

strvec: rename struct fields

2020-07-31T02:18:06Z

The "argc" and "argv" names made sense when the struct was argv_array, but now they're just confusing. Let's rename them to "nr" (which we use for counts elsewhere) and "v" (which is rather terse, but reads well when combined with typical variable names like "args.v"). Note that we have to update all of the callers immediately. Playing tricks with the preprocessor is hard here, because we wouldn't want to rewrite unrelated tokens.

strvec: convert builtin/ callers away from argv_array name

2020-07-28T22:02:18Z

We eventually want to drop the argv_array name and just use strvec consistently. There's no particular reason we have to do it all at once, or care about interactions between converted and unconverted bits. Because of our preprocessor compat layer, the names are interchangeable to the compiler (so even a definition and declaration using different names is OK). This patch converts all of the files in builtin/ to keep the diff to a manageable size. The conversion was done purely mechanically with: git ls-files '*.c' '*.h' | xargs perl -i -pe ' s/ARGV_ARRAY/STRVEC/g; s/argv_array/strvec/g; ' and then selectively staging files with "git add builtin/". We'll deal with any indentation/style fallouts separately. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

strvec: rename files from argv-array to strvec

2020-07-28T22:02:17Z

This requires updating #include lines across the code-base, but that's all fairly mechanical, and was done with: git ls-files '*.c' '*.h' | xargs perl -i -pe 's/argv-array.h/strvec.h/' Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

pack-objects: prefetch objects to be packed

2020-07-21T21:29:42Z

When an object to be packed is noticed to be missing, prefetch all to-be-packed objects in one batch. Signed-off-by: Jonathan Tan Signed-off-by: Junio C Hamano

pack-objects: refactor to oid_object_info_extended

2020-07-21T21:29:42Z

Use oid_object_info_extended() instead of oid_object_info() because a subsequent commit needs to specify an additional flag here. Signed-off-by: Jonathan Tan Signed-off-by: Junio C Hamano
