#include <unistd.h>

First of a series of cleanups to libfetch. Changed files, in alphabetical order: Makefile: Add common.c to SRCS. Make debugging easier by making 'CFLAGS += -DNDEBUG' conditional on DEBUG Don't declare struct {ftp,http}err in {ftp,http}err.c; use struct fetcherr instead. README: Remove the todo list, which is out of date anyway. common.c: (new file) Gather utility functions in this file. Merge the error reporting functions intp _fetch_errstring(), _fetch_seterr() and _fetch_syserr(). Set fetchLastErrCode and fetchLastErrText appropriately when fetchConnect fails. common.h: (new file) Gather internal prototypes and structures in this files. fetch.3: Undocument fetchFreeURL(). Document a few more known bugs. Document fetchLastErrCode and fetchLastErrText. fetch.c: Add descriptive comments to all functions that lacked them. Move fetchConnect() to common.c. Obviate the need for fetchFreeURL(), and remove it. fetch.h: Modify struct url_t so the document part is at the end. ftp.c: Remove code that is duplicated elsewhere. http.c: Remove code that is duplicated elsewhere. Prompted by: jkh
1998-11-05 19:48:17 +00:00
#include "common.h"
Add verbose flag, and support functions. Brucify the Makefile. Differentiate atime and mtime in fetch*Stat(). Fix a few pointer bugs. Tweak some error messages. Don't #include sys/param.h and stdio.h in fetch.h. Document that sys/param.h and stdio.h must be #included before fetch.h.

First step towards SSL support: wrap connections in a 'struct connection' which contains the socket descriptor, the input buffer and (yet unused) SSL state variables. This has the neat side effect of greatly improving reentrance (though we're not *quite* there yet) and opening the door to HTTP connection caching.

First step towards SSL support: wrap connections in a 'struct connection' which contains the socket descriptor, the input buffer and (yet unused) SSL state variables. This has the neat side effect of greatly improving reentrance (though we're not *quite* there yet) and opening the door to HTTP connection caching. This commit is inspired by email conversations with and patches from Henry Whincup <henry@techiebod.com> last fall.

Reindent, and add parentheses to return statements. Some functions in ftp.c and http.c now have exceedingly long lines due to deep nesting; this will be corrected by reorganizing the code in a later revision.

Extensive rewrite of the HTTP code. The new code is significantly cleaner and more robust, and somewhat more efficient. It also handles authorization and redirects properly, and supports timeouts like the FTP code. Many thanks to Umemoto-san for his assistance with IPv6 support, both here and in other parts of libfetch.

Introduce fetchXGet*(), which combine the functionalities of fetchGet*() and fetchStat*(). In most cases, either fetchGet*() or fetchXGet*() is a wrapper around the other; in all cases, calling fetchGet*() is identical to calling fetchXGet*() with the second argument set to NULL.

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*().
