2020-07-30t6301: make hash size independentLibravatar brian m. carlson1-1/+1
Instead of hard-coding a fixed length example object ID in the test, compute one using the translation tables. Move a variable into the setup block so that we can ensure the exit status of test_oid is checked.

2018-05-14t: switch $_z40 to $ZERO_OIDLibravatar brian m. carlson1-1/+1
Switch all uses of $_z40 to $ZERO_OID so that they work correctly with larger hashes. This commit was created by using the following sed command to modify all files in the t directory except t/test-lib.sh: sed -i 's/\$_z40/$ZERO_OID/g' Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-06-17tests: use test_i18n* functions to suppress false positivesLibravatar Vasco Almeida1-5/+5
The test functions test_i18ncmp and test_i18ngrep pretend success if run under GETTEXT_POISON. By using those functions to test output which is correctly marked as translatable, enables one to detect if the strings newly marked for translation are from plumbing output. If they are indeed from plumbing, the test would fail, and the string should be unmarked, since it is not seen by users. Thus, it is productive to not have false positives when running the test under GETTEXT_POISON. This commit replaces normal test functions by their i18n aware variants in use-cases know to be correctly marked for translation, suppressing false positives.

2015-06-08read_loose_refs(): treat NULL_SHA1 loose references as brokenLibravatar Michael Haggerty1-1/+1
NULL_SHA1 is used to indicate an "invalid object name" throughout our code (and the code of other git implementations), so it is vastly more likely that an on-disk reference was set to this value due to a software bug than that NULL_SHA1 is the legitimate SHA-1 of an actual object. Therefore, if a loose reference has the value NULL_SHA1, consider it to be broken. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-06-02for-each-ref: report broken references correctlyLibravatar Michael Haggerty1-1/+1
If there is a loose reference file with invalid contents, "git for-each-ref" incorrectly reports the problem as being a missing object with name NULL_SHA1: $ echo '12345678' >.git/refs/heads/nonsense $ git for-each-ref fatal: missing object 0000000000000000000000000000000000000000 for refs/heads/nonsense With an explicit "--format" string, it can even report that the reference validly points at NULL_SHA1: $ git for-each-ref --format='%(objectname) %(refname)' 0000000000000000000000000000000000000000 refs/heads/nonsense $ echo $? 0 This has been broken since b7dd2d2 for-each-ref: Do not lookup objects when they will not be used (2009-05-27) , which changed for-each-ref from using for_each_ref() to using git_for_each_rawref() in order to avoid looking up the referred-to objects unnecessarily. (When "git for-each-ref" is given a "--format" string that doesn't include information about the pointed-to object, it does not look up the object at all, which makes it considerably faster. Iterating with DO_FOR_EACH_INCLUDE_BROKEN is essential to this optimization because otherwise for_each_ref() would itself need to check whether the object exists as part of its brokenness test.) But for_each_rawref() includes broken references in the iteration, and "git for-each-ref" doesn't itself reject references with REF_ISBROKEN. The result is that broken references are processed *as if* they had the value NULL_SHA1, which is the value stored in entries for broken references. Change "git for-each-ref" to emit warnings for references that are REF_ISBROKEN but to otherwise skip them.

2015-06-02t6301: new tests of for-each-ref error handlingLibravatar Michael Haggerty1-0/+56
Add tests that for-each-ref correctly reports broken loose reference files and references that point at missing objects. In fact, two of these tests fail, because (1) NULL_SHA1 is not recognized as an invalid reference value, and (2) for-each-ref doesn't respect REF_ISBROKEN. Fixes to come. Note that when for-each-ref is run with a --format option that doesn't require the object to be looked up, then we should still notice if a loose reference file is corrupt or contains NULL_SHA1, but we don't notice if it points at a missing object because we don't do an object lookup. This is OK. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
