From: markus schnalke Date: Thu, 12 Apr 2012 21:05:47 +0000 (+0200) Subject: mhshow/mhstore: Removed support for retrieving message/external-body parts. X-Git-Tag: mmh-thesis-end~91 X-Git-Url: http://git.marmaro.de/?a=commitdiff_plain;h=55e1d8c654ee0f7c45b9361ce34617983b454c32;p=mmh mhshow/mhstore: Removed support for retrieving message/external-body parts. These tools won't download the contents automatically anymore. Instead, they print the information needed to get the contents. If someone should really receive one of those rare message/external-body messages, he can do the job manually. We save nearly a thousand lines of code. That's worth it! (The profile entry `nmh-access-ftp' and sbr/ruserpass.c for reading ~/.netrc are gone now.) --- diff --git a/config/config.c b/config/config.c index 70a9a40..1caea47 100644 --- a/config/config.c +++ b/config/config.c @@ -94,9 +94,6 @@ char *nsequence = "Sequence-Negation"; /* profile entries for storage locations */ char *nmhstorage = "nmh-storage"; -/* profile entry for external ftp access command */ -char *nmhaccessftp = "nmh-access-ftp"; - /* Default attachment header field name */ char *attach_hdr = "Attach"; diff --git a/h/mh.h b/h/mh.h index 14f42f4..9eed2d0 100644 --- a/h/mh.h +++ b/h/mh.h @@ -296,7 +296,6 @@ extern char *mhlreply; extern char *mimetypequery; extern char *mimetypequeryproc; extern char *msgprot; -extern char *nmhaccessftp; extern char *nmhstorage; extern char *nsequence; extern char *profile; diff --git a/h/mhparse.h b/h/mhparse.h index af9b8ca..2d88127 100644 --- a/h/mhparse.h +++ b/h/mhparse.h @@ -101,7 +101,6 @@ struct Content { /* pointers to content-specific structures */ void *c_ctparams; /* content type specific data */ - struct exbody *c_ctexbody; /* data for type message/external */ /* function pointers */ InitFunc c_ctinitfnx; /* parse content body */ @@ -210,24 +209,6 @@ struct partial { int pm_stored; }; -/* Structure for message/external */ -struct exbody { - CT eb_parent; /* pointer to controlling content structure */ - CT eb_content; /* pointer to internal content structure */ - char *eb_partno; - char *eb_access; - int eb_flags; - char *eb_name; - char *eb_permission; - char *eb_site; - char *eb_dir; - char *eb_mode; - unsigned long eb_size; - char *eb_server; - char *eb_subject; - char *eb_body; -}; - /* ** APPLICATION content */ @@ -262,7 +243,6 @@ struct str2init { }; extern struct str2init str2cts[]; extern struct str2init str2ces[]; -extern struct str2init str2methods[]; /* ** prototypes @@ -271,6 +251,5 @@ int pidcheck(int); CT parse_mime(char *); int add_header(CT, char *, char *); int get_ctinfo(unsigned char *, CT, int); -int params_external(CT, int); int open7Bit(CT, char **); void close_encoding(CT); diff --git a/h/prototypes.h b/h/prototypes.h index ba33a03..f2c4652 100644 --- a/h/prototypes.h +++ b/h/prototypes.h @@ -85,7 +85,6 @@ void push(void); char *pwd(void); char *mhbasename(char *); void readconfig(struct node **, FILE *, char *, int); -void ruserpass(char *, char **, char **); int seq_addmsg(struct msgs *, char *, int, int, int); int seq_addsel(struct msgs *, char *, int, int); char *seq_bits(struct msgs *); diff --git a/man/mhlist.man1 b/man/mhlist.man1 index b9b098c..f42498b 100644 --- a/man/mhlist.man1 +++ b/man/mhlist.man1 @@ -129,14 +129,6 @@ Note that regardless of the values given to the .B \-type switch, a multipart content (of any subtype listed above) is always acted upon. -Further note that if the -.B \-type -switch is used, and it is desirable to -act on a message/external-body content, then the -.B \-type -switch must -be used twice: once for message/external-body and once for the content -externally referenced. .SH FILES .fc ^ ~ diff --git a/man/mhshow.man1 b/man/mhshow.man1 index 8ebc7ba..9b6465d 100644 --- a/man/mhshow.man1 +++ b/man/mhshow.man1 @@ -111,10 +111,6 @@ name of the content, e.g., \*(lqaudio\*(rq.
