## Test reading a valid z/OS archive.
# RUN: %python %p/Inputs/generate_zos_archive.py --output %t.valid.a \
# RUN:   --symtab "foo.txt:0" --symtab "bar:0" --member foo.txt:abcd
# RUN: llvm-ar t %t.valid.a | FileCheck %s --check-prefix=LIST
# RUN: llvm-nm --print-armap %t.valid.a | FileCheck %s --check-prefix=SYMS
# RUN: llvm-ar p %t.valid.a foo.txt | FileCheck %s --check-prefix=CONTENT

# LIST: foo.txt
# SYMS: Archive map
# SYMS-NEXT: foo.txt in foo.txt
# SYMS-NEXT: bar in foo.txt
# CONTENT: abcd

## Test malformed terminator on member header.
# RUN: %python %p/Inputs/generate_zos_archive.py --output %t.bad_term.a \
# RUN:   --member foo.txt --bad-terminator
# RUN: not llvm-ar t %t.bad_term.a 2>&1 | FileCheck %s --check-prefix=ERR-TERM
# ERR-TERM: terminator characters in archive member

## Test empty UID field on member header.
## We know that the member header starts at offset 8 because no 
## symbol table name is generated.
# RUN: %python %p/Inputs/generate_zos_archive.py --output %t.empty_uid.a \
# RUN:   --member foo.txt --empty-uid
# RUN: not llvm-ar t %t.empty_uid.a 2>&1 | FileCheck %s --check-prefix=ERR-UID
# ERR-UID: UID field is empty or contains only spaces in archive member header at offset 8

## Test leading space in member name.
# RUN: %python %p/Inputs/generate_zos_archive.py --output %t.empty_name.a \
# RUN:   --member foo.txt --empty-name
# RUN: not llvm-ar t %t.empty_name.a 2>&1 | FileCheck %s --check-prefix=ERR-NAME
# ERR-NAME: name contains a leading space for archive member header

## Test truncated z/OS symbol table.
# RUN: %python %p/Inputs/generate_zos_archive.py --output %t.trunc_sym.a \
# RUN:   --symtab-truncated
# RUN: not llvm-ar t %t.trunc_sym.a 2>&1 | FileCheck %s --check-prefix=ERR-TRUNC
# ERR-TRUNC: z/OS archive symbol table is too small to read the symbol count, symbol table size is 2
## Test z/OS symbol table where count exceeds buffer.
# RUN: %python %p/Inputs/generate_zos_archive.py --output %t.bad_count.a \
# RUN:   --symtab-bad-count
# RUN: not llvm-ar t %t.bad_count.a 2>&1 | FileCheck %s --check-prefix=ERR-COUNT
# ERR-COUNT: z/OS archive symbol table names offset {{[0-9]+}} exceeds symbol table size 4

## Test malformed __.SYMDEF header.
# RUN: %python %p/Inputs/generate_zos_archive.py --output %t.bad_sym_hdr.a \
# RUN:   --member foo.txt --symtab foo.txt:0 --malform-symtab-hdr empty-mode
# RUN: not llvm-ar t %t.bad_sym_hdr.a 2>&1 | FileCheck %s --check-prefix=ERR-SYM-HDR
# ERR-SYM-HDR: AccessMode field is empty or contains only spaces

## Test empty LastModified field.
# RUN: %python %p/Inputs/generate_zos_archive.py --output %t.empty_modtime.a \
# RUN:   --member foo.txt --empty-modtime
# RUN: not llvm-ar t %t.empty_modtime.a 2>&1 | FileCheck %s --check-prefix=ERR-MODTIME
# ERR-MODTIME: LastModified field is empty or contains only spaces in archive member header at offset 8

## Test empty GID field.
# RUN: %python %p/Inputs/generate_zos_archive.py --output %t.empty_gid.a \
# RUN:   --member foo.txt --empty-gid
# RUN: not llvm-ar t %t.empty_gid.a 2>&1 | FileCheck %s --check-prefix=ERR-GID
# ERR-GID: GID field is empty or contains only spaces in archive member header at offset 8

## Test that a truncated archive with incomplete member header is rejected.
## The z/OS magic is 8 bytes and a member header requires 60 bytes.
## Writing only 3 bytes after the magic is not enough for a valid header.
## Test that a truncated archive with incomplete member header is rejected.
# RUN: %python %p/Inputs/generate_zos_archive.py --output %t.full.a \
# RUN:   --member foo.txt
# RUN: head -c 28 %t.full.a > %t.badhdr.a
# RUN: not llvm-ar t %t.badhdr.a 2>&1 | FileCheck %s --check-prefix=ERR-CHILD
# ERR-CHILD: truncated or malformed archive
