Regression test for a previous bug in Rust/C FFI for the `Revlog_CAPI` capsule:
|
|
|
in places where `mercurial/cext/revlog.c` function signatures use `Py_ssize_t`
|
|
|
(64 bits on Linux x86_64), corresponding declarations in `rust/hg-cpython/src/cindex.rs`
|
|
|
incorrectly used `libc::c_int` (32 bits).
|
|
|
As a result, -1 passed from Rust for the null revision became 4294967295 in C.

changelog altered
|
|
|
-----------------
|
|
|
|
|
|
If the nodemap is not gated behind a requirements, an unaware client can alter
|
|
|
the repository so the revlog used to generate the nodemap is not longer
|
|
|
compatible with the persistent nodemap. We need to detect that.
|
|
|
|
|
|
$ hg up "$NODE~5"
|
|
|
0 files updated, 0 files merged, 4 files removed, 0 files unresolved
|
|
|

|
|
|

|
|
|
|
|
|
$ hg --config extensions.strip= strip --rev "$NODE~1" --no-backup
|
|
|
|
|
|
the nodemap should detect the changelog have been tampered with and recover.

Check race condition when multiple process write new data to the repository
|
|
|
---------------------------------------------------------------------------
|
|
|
|
|
|
In this test, we check that two writers touching the repositories will not
|
|
|
overwrite each other data. This test is prompted by the existent of issue6554.
|
|
|
Where a writer ended up using and outdated docket to update the repository. See
|
|
|
the dedicated extension for details on the race windows and read/write schedule
|
|
|
necessary to end up in this situation: testlib/persistent-nodemap-race-ext.py
|
|
|
|
|
|
The issue was initially observed on a server with a high push trafic, but it
|
|
|
can be reproduced using a share and two commiting process which seems simpler.
|
|
|
|
|
|
The test is Rust only as the other implementation does not use the same
|
|
|
read/write patterns.

We get a usable nodemap, so no rewrite would be needed and the metadata should be identical
|
|
|
(ie: the following diff should be empty)
|
|
|
|
|
|
This isn't the case for the `no-rust` `no-pure` implementation as it use a very minimal nodemap implementation that unconditionnaly rewrite the nodemap "all the time".

A full nodemap is generated
|

(ideally this test would append enough data to make sure the nodemap data file
|

get changed, however to make thing simpler we will force the regeneration for

|
|
this test.
