From 1f993cacd1ac269ea4e7a77c57edbce732b9e8b5 Mon Sep 17 00:00:00 2001 From: Not Zed Date: Thu, 6 Jun 2002 09:53:36 +0000 Subject: Remove the CONF_DEFAULT_PATH entry, as this is handled by the url config 2002-06-04 Not Zed * providers/local/camel-local-provider.c: Remove the CONF_DEFAULT_PATH entry, as this is handled by the url config stuff. This made it basically impossible to configure any local folder from the gui. * providers/local/camel-local-folder.c (local_refresh_info): Force a refresh. Should work for all local folders to force them to refresh. * providers/local/camel-maildir-folder.c (maildir_refresh_info): Removed, moved into camel-local-folder. * providers/local/camel-mh-summary.c (mh_summary_next_uid_string): Once we assign or get a uid, tell the summary of this, so the next uid we get will be higher than any previously. * camel-object.c (camel_object_ref, camel_object_unref): I got sick of casting, these now take void * like they should, and perform their own run-time type checking. * providers/local/camel-mh-store.c (recursive_scan): Changed to use stat, not lstat (*shrug* maybe someone wants to softlink their maildir tree?). (inode_hash): (inode_equal): (inode_free): Copied from camel-maildir store (should put into camel-local-store or utils?). (recursive_scan): Changed to check for re-visiting inodes. Also, it builds the tree itself, rather than using folder_info_build. (add_folder): Changed to folder_info_new. (recursive_scan): Properly honour the recursive flag. Also, lookup unread count from folder. (folder_info_new): Init unread message count to -1, since we dont know yet. (folder_info_new): Take the name as an argument, and perform the merging here. (folders_update): Util func to add/remove folders from .folders file. I'm assuming its sorted. (get_folder): Add the folder to .folders if we created a new one, and if it exists. (delete_folder): Remove from .folders, etc. (folders_scan): If we have a .folders file, read and use that instead. (recursive_scan): Handle scanning from a particular directory properly. (rename_folder): Implement so we can track any changes to the .folders file if its turned on. ** Applied patch below from Greg Hudson. 2002-05-10 Greg Hudson * camel-mh-store.c (get_inbox, get_folder_info, recursive_scan, add_folder): Implement support for MH stores. * camel-mh-summary.c (mh_summary_check, sort_uid_cmp): Sort MH messages by message number (uid), like we sort maildir messages by date. * camel-local-provider.c (mh_provider): Turn on source and store flags. svn path=/trunk/; revision=17130 --- camel/providers/local/camel-mh-store.c | 401 ++++++++++++++++++++++++++++++++- 1 file changed, 400 insertions(+), 1 deletion(-) (limited to 'camel/providers/local/camel-mh-store.c') diff --git a/camel/providers/local/camel-mh-store.c b/camel/providers/local/camel-mh-store.c index 8b8c2e5f0e..f653fdb408 100644 --- a/camel/providers/local/camel-mh-store.c +++ b/camel/providers/local/camel-mh-store.c @@ -27,32 +27,48 @@ #include #include #include +#include #include "camel-mh-store.h" #include "camel-mh-folder.h" #include "camel-exception.h" #include "camel-url.h" +#include "camel-private.h" + +#include +#include static CamelLocalStoreClass *parent_class = NULL; +#define d(x) + /* Returns the class for a CamelMhStore */ #define CMHS_CLASS(so) CAMEL_MH_STORE_CLASS (CAMEL_OBJECT_GET_CLASS(so)) #define CF_CLASS(so) CAMEL_FOLDER_CLASS (CAMEL_OBJECT_GET_CLASS(so)) #define CMHF_CLASS(so) CAMEL_MH_FOLDER_CLASS (CAMEL_OBJECT_GET_CLASS(so)) +static void construct (CamelService *service, CamelSession *session, CamelProvider *provider, CamelURL *url, CamelException *ex); static CamelFolder *get_folder(CamelStore * store, const char *folder_name, guint32 flags, CamelException * ex); +static CamelFolder *get_inbox (CamelStore *store, CamelException *ex); static void delete_folder(CamelStore * store, const char *folder_name, CamelException * ex); +static void rename_folder(CamelStore *store, const char *old, const char *new, CamelException *ex); +static CamelFolderInfo * get_folder_info (CamelStore *store, const char *top, guint32 flags, CamelException *ex); static void camel_mh_store_class_init(CamelObjectClass * camel_mh_store_class) { CamelStoreClass *camel_store_class = CAMEL_STORE_CLASS(camel_mh_store_class); - /*CamelServiceClass *camel_service_class = CAMEL_SERVICE_CLASS(camel_mh_store_class);*/ + CamelServiceClass *camel_service_class = CAMEL_SERVICE_CLASS(camel_mh_store_class); parent_class = (CamelLocalStoreClass *)camel_type_get_global_classfuncs(camel_local_store_get_type()); /* virtual method overload, use defaults for most */ + camel_service_class->construct = construct; + camel_store_class->get_folder = get_folder; + camel_store_class->get_inbox = get_inbox; camel_store_class->delete_folder = delete_folder; + camel_store_class->rename_folder = rename_folder; + camel_store_class->get_folder_info = get_folder_info; } CamelType camel_mh_store_get_type(void) @@ -72,6 +88,103 @@ CamelType camel_mh_store_get_type(void) return camel_mh_store_type; } +static void +construct (CamelService *service, CamelSession *session, CamelProvider *provider, CamelURL *url, CamelException *ex) +{ + CamelMhStore *mh_store = (CamelMhStore *)service; + + CAMEL_SERVICE_CLASS (parent_class)->construct (service, session, provider, url, ex); + if (camel_exception_is_set (ex)) + return; + + if (camel_url_get_param(url, "dotfolders")) + mh_store->flags |= CAMEL_MH_DOTFOLDERS; +} + +enum { + UPDATE_NONE, + UPDATE_ADD, + UPDATE_REMOVE, +}; + +/* update the .folders file if it exists, or create it if it doesn't */ +static void +folders_update(const char *root, const char *folder, int mode) +{ + char *tmp, *tmpnew, *line = NULL; + CamelStream *stream, *in = NULL, *out = NULL; + + tmpnew = alloca(strlen(root)+16); + sprintf(tmpnew, "%s.folders~", root); + + out = camel_stream_fs_new_with_name(tmpnew, O_WRONLY|O_CREAT|O_TRUNC, 0666); + if (out == NULL) + goto fail; + + tmp = alloca(strlen(root)+16); + sprintf(tmp, "%s.folders", root); + stream = camel_stream_fs_new_with_name(tmp, O_RDONLY, 0); + if (stream) { + in = camel_stream_buffer_new(stream, CAMEL_STREAM_BUFFER_READ); + camel_object_unref(stream); + } + if (in == NULL || stream == NULL) { + if (mode == UPDATE_ADD && camel_stream_printf(out, "%s\n", folder) == -1) + goto fail; + goto done; + } + + while ((line = camel_stream_buffer_read_line((CamelStreamBuffer *)in))) { + int copy = TRUE; + + switch (mode) { + case UPDATE_REMOVE: + if (strcmp(line, folder) == 0) + copy = FALSE; + break; + case UPDATE_ADD: { + int cmp = strcmp(line, folder); + + if (cmp > 0) { + /* found insertion point */ + if (camel_stream_printf(out, "%s\n", folder) == -1) + goto fail; + mode = UPDATE_NONE; + } else if (tmp == 0) { + /* already there */ + mode = UPDATE_NONE; + } + break; } + case UPDATE_NONE: + break; + } + + if (copy && camel_stream_printf(out, "%s\n", line) == -1) + goto fail; + + g_free(line); + line = NULL; + } + + /* add to end?
