Cleanups/renaming of EXTERNAL_TO_C_STRING and friends -------------------- ChangeLog entries follow: -------------------- modules/ChangeLog addition: 2010-02-05 Ben Wing <ben@xemacs.org> * postgresql/postgresql.c: * postgresql/postgresql.c (CHECK_LIVE_CONNECTION): * postgresql/postgresql.c (Fpq_connectdb): * postgresql/postgresql.c (Fpq_connect_start): * postgresql/postgresql.c (Fpq_lo_import): * postgresql/postgresql.c (Fpq_lo_export): * ldap/eldap.c (Fldap_open): * ldap/eldap.c (Fldap_search_basic): * ldap/eldap.c (Fldap_add): * ldap/eldap.c (Fldap_modify): * ldap/eldap.c (Fldap_delete): * canna/canna_api.c (Fcanna_initialize): * canna/canna_api.c (Fcanna_store_yomi): * canna/canna_api.c (Fcanna_parse): * canna/canna_api.c (Fcanna_henkan_begin): EXTERNAL_TO_C_STRING returns its argument instead of storing it in a parameter, and is renamed to EXTERNAL_TO_ITEXT. Similar things happen to related macros. See entry in src/ChangeLog. More Mule-izing of postgresql.c. Extract out common code between `pq-connectdb' and `pq-connect-start'. Fix places that signal an error string using a formatted string to instead follow the standard and have a fixed reason followed by the particular error message stored as one of the frobs.

win32.c (mswindows_read_link_1): Changes involving external/internal format conversion, mostly code cleanup and renaming. 1. Eliminate the previous macros like LISP_STRING_TO_EXTERNAL that stored its result in a parameter. The new version of LISP_STRING_TO_EXTERNAL returns its result through the return value, same as the previous NEW_LISP_STRING_TO_EXTERNAL. Use the new-style macros throughout the code. 2. Rename C_STRING_TO_EXTERNAL and friends to ITEXT_TO_EXTERNAL, in keeping with overall naming rationalization involving Itext and related types. Macros involved in previous two: EXTERNAL_TO_C_STRING -> EXTERNAL_TO_ITEXT EXTERNAL_TO_C_STRING_MALLOC -> EXTERNAL_TO_ITEXT_MALLOC SIZED_EXTERNAL_TO_C_STRING -> SIZED_EXTERNAL_TO_ITEXT SIZED_EXTERNAL_TO_C_STRING_MALLOC -> SIZED_EXTERNAL_TO_ITEXT_MALLOC C_STRING_TO_EXTERNAL -> ITEXT_TO_EXTERNAL C_STRING_TO_EXTERNAL_MALLOC -> ITEXT_TO_EXTERNAL_MALLOC LISP_STRING_TO_EXTERNAL LISP_STRING_TO_EXTERNAL_MALLOC LISP_STRING_TO_TSTR C_STRING_TO_TSTR -> ITEXT_TO_TSTR TSTR_TO_C_STRING -> TSTR_TO_ITEXT The following four still return their values through parameters, since they have more than one value to return: C_STRING_TO_SIZED_EXTERNAL -> ITEXT_TO_SIZED_EXTERNAL LISP_STRING_TO_SIZED_EXTERNAL C_STRING_TO_SIZED_EXTERNAL_MALLOC -> ITEXT_TO_SIZED_EXTERNAL_MALLOC LISP_STRING_TO_SIZED_EXTERNAL_MALLOC Sometimes additional casts had to be inserted, since the old macros played strange games and completely defeated the type system of the store params. 3. Rewrite many places where direct calls to TO_EXTERNAL_FORMAT occurred with calls to one of the convenience macros listed above, or to make_extstring(). 4. Eliminate SIZED_C_STRING macros (they were hardly used, anyway) and use a direct call to TO_EXTERNAL_FORMAT or TO_INTERNAL_FORMAT. 4. Use LISP_PATHNAME_CONVERT_OUT in many places instead of something like LISP_STRING_TO_EXTERNAL(..., Qfile_name). 5. Eliminate some temporary variables that are no longer necessary now that we return a value rather than storing it into a variable. 6. Some Mule-izing in database.c. 7. Error functions: -- A bit of code cleanup in maybe_signal_error_1. -- Eliminate report_file_type_error; it's just an alias for signal_error_2 with params in a different order. -- Fix some places in the hostname-handling code that directly inserted externally-retrieved error strings into the supposed ASCII "reason" param instead of doing the right thing and sticking text descriptive of what was going on in "reason" and putting the external message in a frob. 8. Use Ascbyte instead of CIbyte in process-unix.c and maybe one or two other places. 9. Some code cleanup in copy_in_passwd() in sysdep.c. 10. Fix a real bug due to accidental variable shadowing in tstr_to_local_file_format() in win32.c.
