Change code that printed its own "fatal: " message and exited with a
status code of 128 to use the die_message() function added in a
preceding commit.
This change also demonstrates why the return value of
die_message_routine() needed to be that of "report_fn". We have
callers such as the run-command.c::child_err_spew() which would like
to replace its error routine with the return value of
"get_die_message_routine()".

When we're hashing a value which is going to be an object ID, we want to
zero-pad that value if necessary. To do so, use the final_oid_fn
instead of the final_fn anytime we're going to create an object ID to
ensure we perform this operation.

In the future, we'll want oidread to automatically set the hash
algorithm member for an object ID we read into it, so ensure we use
oidread instead of hashcpy everywhere we're copying a hash value into a
struct object_id.

Add and apply a semantic patch for converting code that open-codes
CALLOC_ARRAY to use it instead. It shortens the code and infers the
element size automatically.

Code clean-up.
* jk/fast-import-marks-cleanup:
fast-import: remove duplicated option-parsing line
|
|
Commit 1bdca81641 (fast-import: add options for rewriting submodules,
2020-02-22) accidentally added two lines parsing the option
"rewrite-submodules-from". This didn't do anything in practice, because
they're in an if/else chain and so the second one can never trigger.

Fast-import stores its marks in a trie-like structure made of mark_set
structs. Each struct has a fixed size (1024). If our id number is too
large to fit in the struct, then we allocate a new struct which shifts
the id number by 10 bits. Our original struct becomes a child node
of this new layer, and the new struct becomes the top level of the trie.
This scheme was broken by ddddf8d7e2 (fast-import: permit reading
multiple marks files, 2020-02-22). Before then, we had a top-level
"marks" pointer, and the push-down worked by assigning the new top-level
struct to "marks". But after that commit, insert_mark() takes a pointer
to the mark_set, rather than using the global "marks". It continued to
assign to the global "marks" variable during the push down, which was
wrong for two reasons:
- we added a call in option_rewrite_submodules() which uses a separate
mark set; pushing down on "marks" is outright wrong here. We'd
corrupt the "marks" set, and we'd fail to correctly store any
submodule mappings with an id over 1024.
- the other callers passed "marks", but the push-down was still wrong.
In read_mark_file(), we take the pointer to the mark_set as a
parameter. So even though insert_mark() was updating the global
"marks", the local pointer we had in read_mark_file() was not
updated. As a result, we'd add a new level when needed, but then the
next call to insert_mark() wouldn't see it! It would then allocate a
new layer, which would also not be seen, and so on. Lookups for the
lost layers obviously wouldn't work, but before we even hit any
lookup stage, we'd generally run out of memory and die.
Our tests didn't notice either of these cases because they didn't have
enough marks to trigger the push-down behavior. The new tests in t9304
cover both cases (and fail without this patch).
We can solve the problem by having insert_mark() take a pointer-to-pointer
of the top-level of the set. Then our push down can assign to it in a
way that the caller actually sees. Note the subtle reordering in
option_rewrite_submodules(). Our call to read_mark_file() may modify our
top-level set pointer, so we have to wait until after it returns to
assign its value into the string_list.

Call write_pack_header() to hash and write a pack header instead of
open-coding this function. This gets rid of duplicate code and of the
magic version number 2 -- which has been used here since c90be46abd
(Changed fast-import's pack header creation to use pack.h, 2006-08-16)
and in pack.h (again) since 29f049a0c2 (Revert "move pack creation to
version 3", 2006-10-14).

Trim an unused binary and turn a bunch of commands into built-in.
* jk/slimmed-down:
drop vcs-svn experiment
make git-fast-import a builtin
make git-bugreport a builtin
make credential helpers builtins
Makefile: drop builtins from MSVC pdb list

There's no reason that git-fast-import benefits from being a separate
binary. And as it links against libgit.a, it has a non-trivial disk
footprint. Let's make it a builtin, which reduces the size of a stripped
installation from 22MB to 21MB.
