Second of a series of cleanups to libfetch.
This commit introduces the following features:
a) the fetchStat*() functions, which return meta-information for a
document, such as size, modification time, etc.
b) the use of the com_err(3) facilities to report errors.
It also fixes a bunch of style bugs and a few logic bugs and somewhat
improves the man page.
Changed files, in alphabetical order:
Makefile:
Don't generate macros in {ftp,http}err.c.
Generate category fields for the error message lists.
Compile the error table.
Install fetch_err.h along with fetch.h.
common.c:
Remove the _netdb_errstring() macro, and add FETCH_ERR_NETDB to the
error code in the _netdb_seterr() macro.
Add categories to the _netdb_errlist table.
Report errors through the Common Error library.
common.h:
Add the DEBUG macros.
Add prototype for fetchConnect().
Remove the prototype for _fetch_errstring(), which is local to common.c
Add a categroy field to struct fetcherr, and define constants for
error categories.
Define macros for _{url,netdb,ftp,http}_seterr().
errors.et: (new file)
List error categories.
fetch.3:
Document the fetchStat*() functions.
Move the "unimplemented functionality" comments from NOTES to BUGS.
Document that applications which use libfetch must also use
libcom_err, and list existing error codes.
Undocument fetchLastErr{Code,String}.
Remove the (empty) DIAGNOSTICS section.
Mention Eugene Skepner in the AUTHORS section.
fetch.c:
Move the DEBUG macros to common.c
Add fetchStat() and fetchStatURL().
Generate error messages for URL parser errors, and fix a minor bug
in the parser.
Use 'struct url' instead of 'url_t'.
Remove fetchLastErr{Code,String}.
fetch.h:
Use 'struct url' instead of 'url_t', and remove the typedef.
Define struct url_stat (used by fetchStat()).
Add prototypes for fetchStat*().
Remove the declarations for fetchLastErr{Code,String}.
Include fetch_err.h.
fetch_err.et: (new file)
Error table for libfetch.
file.c:

Second of a series of cleanups to libfetch.
This commit introduces the following features:
a) the fetchStat*() functions, which return meta-information for a
document, such as size, modification time, etc.
b) the use of the com_err(3) facilities to report errors.
It also fixes a bunch of style bugs and a few logic bugs and somewhat
improves the man page.
Changed files, in alphabetical order:
Makefile:
Don't generate macros in {ftp,http}err.c.
Generate category fields for the error message lists.
Compile the error table.
Install fetch_err.h along with fetch.h.
common.c:
Remove the _netdb_errstring() macro, and add FETCH_ERR_NETDB to the
error code in the _netdb_seterr() macro.
Add categories to the _netdb_errlist table.
Report errors through the Common Error library.
common.h:
Add the DEBUG macros.
Add prototype for fetchConnect().

These functions implement a high-level library for retrieving and
|
|
|
|
|
|
uploading files using Uniform Resource Locators (URLs).

.Fn fetchParseURL
|
|
|
|
|
|
takes a URL in the form of a null-terminated string and splits it into
|
|
|
|
|
|
its components function according to the Common Internet Scheme Syntax
|
2000-05-11 15:22:52 +00:00
|
|
|
|
detailed in RFC1738.
|
|
|
|
|
|
A regular expression which produces this syntax is:
|
2000-05-11 13:31:02 +00:00
|
|
|
|
.Bd -literal
|
|
|
|
|
|
<scheme>:(//(<user>(:<pwd>)?@)?<host>(:<port>)?)?/(<document>)?

|
|
.Ed
|
|
|
|
|
|
.Pp
|
2000-10-12 22:11:26 +00:00
|
|
|
|
If the URL does not seem to begin with a scheme name, the following
|
|
|
|
|
|
syntax is assumed:
|
|
|
|
|
|
.Bd -literal
|
|
|
|
|
|
((<user>(:<pwd>)?@)?<host>(:<port>)?)?/(<document>)?

|
|
|
|
|
.Pp
|
2000-05-11 13:31:02 +00:00
|
|
|
|
Note that some components of the URL are not necessarily relevant to
|
|
|
|
|
|
all URL schemes.
|
2000-10-12 22:11:26 +00:00
|
|
|
|
For instance, the file scheme only needs the <scheme> and <document>
|
|
|
|
|
|
components.

Second of a series of cleanups to libfetch.
This commit introduces the following features:
a) the fetchStat*() functions, which return meta-information for a
document, such as size, modification time, etc.
b) the use of the com_err(3) facilities to report errors.
It also fixes a bunch of style bugs and a few logic bugs and somewhat
improves the man page.
Changed files, in alphabetical order:
Makefile:
Don't generate macros in {ftp,http}err.c.
Generate category fields for the error message lists.
Compile the error table.
Install fetch_err.h along with fetch.h.
common.c:
Remove the _netdb_errstring() macro, and add FETCH_ERR_NETDB to the
error code in the _netdb_seterr() macro.
Add categories to the _netdb_errlist table.
Report errors through the Common Error library.
common.h:
Add the DEBUG macros.
Add prototype for fetchConnect().
Remove the prototype for _fetch_errstring(), which is local to common.c
Add a categroy field to struct fetcherr, and define constants for
error categories.
Define macros for _{url,netdb,ftp,http}_seterr().
errors.et: (new file)
List error categories.
fetch.3:
Document the fetchStat*() functions.
Move the "unimplemented functionality" comments from NOTES to BUGS.
Document that applications which use libfetch must also use

Second of a series of cleanups to libfetch.
This commit introduces the following features:
a) the fetchStat*() functions, which return meta-information for a
document, such as size, modification time, etc.
b) the use of the com_err(3) facilities to report errors.
It also fixes a bunch of style bugs and a few logic bugs and somewhat
improves the man page.

Second of a series of cleanups to libfetch.
This commit introduces the following features:
a) the fetchStat*() functions, which return meta-information for a
document, such as size, modification time, etc.
b) the use of the com_err(3) facilities to report errors.
It also fixes a bunch of style bugs and a few logic bugs and somewhat
improves the man page.
Changed files, in alphabetical order:
Makefile:
Don't generate macros in {ftp,http}err.c.
Generate category fields for the error message lists.
Compile the error table.
Install fetch_err.h along with fetch.h.
common.c:
Remove the _netdb_errstring() macro, and add FETCH_ERR_NETDB to the

errors.et: (new file)
List error categories.

Document the fetchStat*() functions.
Move the "unimplemented functionality" comments from NOTES to BUGS.

Undocument fetchLastErr{Code,String}.
Remove the (empty) DIAGNOSTICS section.

Second of a series of cleanups to libfetch.
This commit introduces the following features:
a) the fetchStat*() functions, which return meta-information for a
document, such as size, modification time, etc.
b) the use of the com_err(3) facilities to report errors.
It also fixes a bunch of style bugs and a few logic bugs and somewhat
improves the man page.

Error numbers are unique only within a certain context; the error

codes used for FTP and HTTP overlap, as do those used for resolver and

system errors.
|
|
|

For instance, error code 202 means "Command not

implemented, superfluous at this site" in an FTP context and
